Repair

IN Lately more and more more owners apartments in multi-storey buildings decide to expand their area by adding a balcony. This is an excellent option if you figure out how to properly insulate it from the inside and equip it.

If the balcony is not glazed, windows must be installed before insulation. It is better to choose high-quality double-glazed windows without saving, because the amount of heat in the apartment depends on them. Elements of window structures should fit together as closely as possible to prevent drafts from entering the house.

The balcony is the part of the building that needs insulation more than others, because not all residents use it only as a warehouse. Increasingly, people are starting to equip their balconies as additional space, for example, a personal office. For these and not only reasons, it is necessary to properly insulate the structure from the inside.

Stages of insulating a balcony

In modern technologies for insulating open suspended structures (balconies), four types of materials are used as internal insulation: polystyrene foam, penoplex, penofol and mineral wool. Let's consider the technological features of installation and types of cotton insulation used for thermal insulation of balconies.

playlist

1. First, existing cracks are sealed. You need to carefully examine the balcony and determine their location. You can fix the problem with the help of polyurethane foam, even if the cracks are quite wide, you just need to choose a high-quality one, for example, “Macroflex”, “Soudal”, “Moment Montazh”. After the foam has dried, the excess is trimmed with a utility knife.

2. Waterproofing the balcony from the inside. For these purposes, you can use penetrating waterproofing "Aquatron", "Penetron" and the like. They are applied using a brush, roller or spray method. The advantage of penetrating waterproofing is that it penetrates into the walls, making them more resistant to low temperatures and more durable. In addition, waterproofing eliminates all microcracks that are not visible to the naked eye.

3. Laying thermal insulation material. For this purpose, you can use polystyrene foam, polyurethane foam, penoplex, mineral boards, etc.

Laying vapor barrier. You can use polymer “breathable” membranes, vapor barrier films “Izospan”, “Rockwool” and the like, or, as a last resort, penofol, which is laid with the foil side facing the apartment. So the heat leaving the room will return back.

4. Exterior decoration ceiling and walls on the balcony.

Insulation option in which there is no additional insulation

This technique can be used provided that materials with low vapor permeability are available ( we're talking about about materials such as polystyrene foam, penoplex, or extruded polystyrene foam).

No. 1. Insulating a balcony with polystyrene foam: sequence of work

If you chose polystyrene foam as insulation, then the sequence of work is as follows:

After all the cracks have been sealed and waterproofing has been completed, the surface is treated with a deep penetration primer, for example Ceresite. This can be done with a brush or spray. The primer is poured into a bucket or other container that you don’t mind, then applied to the surface. Carefully work on the walls, ceiling and floor to achieve maximum adhesion of the insulation boards to them.

After applying the primer, you must wait at least six hours, then continue work. If the wall is made of slag concrete, then the primer is carried out twice.

We rested - let's continue. Unpack the polystyrene foam boards. They are attached with glue and fasteners. The glue must be prepared according to the instructions and mixed thoroughly. Then apply it to the first sheet, which is glued to the surface (do not forget to retreat three centimeters from the edges, and leave small gaps between the sheets). Install polystyrene foam sheets in a checkerboard pattern.

Whether to install a vapor barrier or not is up to you. In this case, it is not necessary to do it.

Installation of reinforcing mesh. When all the slabs are securely fixed to the walls or ceiling, the reinforcing mesh should be installed. To do this, the surface of the slabs is treated with glue, and perforated corners are fixed at their corners. The reinforcing mesh is rolled onto the glued surface with a roller, then another layer of glue is applied. When the wall is dry, it is primed and plastered.

No. 2. Balcony insulation with penoplex

Penoplex is actively used for insulating rooms. You can attach it to the surface using bitumen mastics, polyurethane foam or mushroom dowels. Consider the option of mounting on polyurethane foam.

So. Waterproofing is done. Polyurethane foam is applied around the perimeter of the insulation board. It's enough. After application, wait a couple of seconds and fix the slab on the insulated surface. The next slab is laid end to end with the first one. After two days, you can additionally secure the slabs with dowels. Then the whole process is repeated in a similar order as described above. Finish at your own discretion. You can sew up the insulation boards with plastic panels; they look very original.

Advice. If the balcony is intended only for storing essential items, then it is enough to insulate the walls in one layer. If you need to insulate more thoroughly, it is better to lay the insulation in two layers.

No. 3. Balcony insulation with mineral wool: technology features

Insulation of balconies with mineral wool is carried out under the constructed sheathing. A lining is attached on top of the frame - wooden or plastic panels with special grooves.

A well-known fact is the construction recommendation to carry out insulation from the outside of the building. However, when insulating balconies and loggias, it is often not possible to place the insulation material outside. The internal placement of the insulation layer requires certain calculations, adherence to technology and the correct selection of materials, so that in the future the work performed does not lead to wetness of the walls, corners and ceilings inside the external structure.

Kinds mineral wool

Depending on the raw materials used in production, there are three main types of mineral wool: glass, stone and slag. All three materials are suitable for insulation work.

Mineral wool is a soft material that does not have rigid dimensions. It is supplied in the form of rolls (they are unwound into a track before laying) or soft mats. Sometimes one side of the insulation is covered with aluminum foil to enhance the thermal insulation properties.

Important! When installing, the foil should be located on the side of the room. Internal heat the room will be reflected from the foil surface back into the living space.

The thickness of the mineral wool layer determines the quality of insulation and varies in size from 20 to 200 mm.

Mineral wool installation technology

Any type of mineral wool is mounted under the frame, located between outer wall(ceiling, roof) and frame supports. Wooden sticks or metal profiles can be used as supports, depending on what kind of cladding will be used in the future.

When using lining for finishing wall cladding, the lathing frame is constructed of wood. Wooden sticks with a cross section of 150 - 250 cm 2 are installed, and you can save a little inner space balcony, installing sticks of rectangular rather than square cross-section (30 × 50 cm 2, 30 × 70 cm 2).

All racks and horizontal lathing strips are installed below the level. Fastening vertical racks to the concrete surface of the ceiling and floor is carried out with anchor bolts. Horizontal ones are attached to the vertical supports. If the future cladding is made of plastic lining, the horizontal strips are attached at three levels: knee, hip, shoulder.

For internal insulation with mineral wool, it is mandatory to install a vapor barrier. The cotton material itself is breathable; it easily allows gaseous substances (air, steam) to pass through.

Considering that with internal insulation, the point of condensation formation moves into the insulation, it is necessary to limit the penetration of steam or air from living quarters into the construction wool. For these purposes, a vapor barrier film is laid between the mineral wool and the finishing.

Interior decoration

Purpose of interior decoration:

Close the heat insulation material from the living space.
Create an aesthetically pleasing interior covering for the walls of a room or insulated loggia.

There are various materials for interior decoration of balconies (plasterboard, wood, plastic, plaster). With a previously constructed lattice frame, finishing is done by hanging various types panels: plywood, MDF, wood or plastic lining.

The final finishing with clapboard is carried out by covering the walls with wooden (or plastic) clapboard panels, which have special grooves around the perimeter for ease of installation and tightness of fastening. At the same time, plastic lining is often a cheaper simulator wooden covering, laid according to internal walls balcony (or loggia). It is characterized by less strength and rigidity.

Wooden carriage panels are reliable, environmentally friendly, and have sufficient flooring rigidity. The ceiling of the loggia can be covered with plastic clapboard; the floor is covered with wood; as for the walls, both types of wagon covering (plastic and wood) can be used here.

It is recommended to start clapboard cladding from the corner. Each panel is checked for verticality with a level and fixed to the sheathing with a special fastener (clamp). You can fix the carriage panel with small nails.

After finishing, the inner surface is treated with a compound that protects the wood from moisture and destruction.

Problems encountered when insulating a balcony internally

1. When covering walls, ceilings and floors with insulating material, the area of the room inevitably decreases. And this drawback is not the only one.

2. In many structures, condensation often occurs, which is difficult to get rid of when everything construction works have already been produced. Why does excess moisture appear?

The insulating structure installed on the balcony includes the following elements:

external fencing located on the street; insulation material; warm room.

Air masses tend to get out, and their moisture, passing through the insulation, settles on the outer fence in the form of condensation. The insulation gets wet and completely loses its performance characteristics.

Warm vapors, when faced with a cold fence, also turn into liquid state. Excess moisture in the room causes many problems: for example, mold or rot. wooden elements designs. That is why you need to know how to properly insulate your balcony.

This can be done from the inside in two ways.

Hydrobarrier

A hydrobarrier is a special design that prevents moisture condensation on the outer fence. Its installation technology includes certain stages:

installation of vapor barrier;
finishing with facing materials.

The hydrobarrier makes it possible to use even materials that do not tolerate moisture when insulating from the inside. Polyethylene or foil serves as insulation.

Important! All seams must be sealed with construction tape.in order to best insulate the balcony.

The disadvantage of this insulation method is that the walls cannot breathe.

Insulation without additional insulation

It is possible to insulate a balcony from the inside in this way only if there are materials with low vapor permeability: polystyrene foam, penoplex or extruded polystyrene foam. The design includes:

fiberglass mesh, also mounted with glue; finishing.

Advice! For better fastening For insulation, you can use plastic dowels.

No adhesive is required for thermal insulation with polystyrene foam. This material is applied to the insulated surface using a sprayer, foams and dries.

Innovative insulation from TechnoNIKOL LOGICPIR Balcony is suitable for walls, ceilings, floors. saves space - plate thickness from 20 mm.

retains heat thanks to its unique thermal conductivity of 0.022 W/m°K (compare with glass wool 0.032-0.041 W/m°K);
protected from moisture, rot, mold and fire (flammability group G1 according to GOST 30244-94);
will last long years(the insulation retains its properties for 50 years).

Advice! When insulating a balcony from the inside with polystyrene foam, it is better to make a layer of material about 80 mm thick. The vapor permeability of extruded polystyrene foam is lower than that of simple polystyrene, so its layer can be even smaller.

Floor insulation

After insulating the balcony walls, the floor should be insulated. If you correctly calculate the amount of insulation and the thickness of its layer, you can make the floor on the balcony at the same level as in the other rooms.

At the first stage of work, the slab is cleaned of dirt, debris and fallen plaster. Then the floor is covered with foil and penofol. The second stage is attaching the sheathing, previously cut with a jigsaw. Insulation boards (preferably polystyrene foam) are laid between its beams, and the gaps between them are filled with foam. The final stage is the installation of flooring, linoleum or parquet and baseboards.

This design can raise the floor on the balcony by about 150 mm.

Electrically heated floor

It is possible to insulate the floor using modern technologies. Then the balcony will be practically no different from other rooms. Installing electric heat tracing is a relatively simple process, but the energy costs add up significantly.

To heat the balcony floor from the inside, a special electric cable is installed.

Important! The cable must not be exposed to moisture under any circumstances.

Components of the insulating structure:

Ceiling insulation

Advice! If the neighbors living on the floor above have already insulated their balcony, there is no need to insulate the ceiling.

The most optimal material for ceiling insulation is polystyrene foam. It weighs very little, which is very important in this case. Its main layer is complemented by foil, which acts as a vapor barrier and heat reflector. The foiled polystyrene foam is fixed with polyurethane foam glue and disc-shaped dowels. All seams are sealed with special metal tape.

The foam is attached to aluminum hangers using the same combined method.

Important! The insulation sheets should fit together as closely as possible.

All cracks are filled with polyurethane foam with special care, so every, even the smallest, hole can make all work absolutely useless.

You can insulate a balcony from the inside either on your own or by using the services of professionals. However, these construction works can be simple if you use tips and carefully understand the technology.

Mistakes when insulating a balcony

Until recently, the balconies of city apartments served as a kind of storage room - people stored preserved food and various things there. Why, they took everyone out onto the balconies unnecessary trash, which it was a shame to throw away. However, today these premises are increasingly used as additional living space. And to implement such an idea, you need to take care of insulating the balcony.

If you insulate your balcony, you will be able to not only expand the living space of your apartment relatively cheaply, but also significantly reduce heat loss from your home. The fact is that it is through the balconies that most of the heat escapes. But in order for everything to be done efficiently, you need to know where to start. With a well-designed scheme, turn cold balcony albeit in a small, but almost complete room, it will be much easier.

So, first sketch out a rough work plan - it will include:

Important information! The balcony can be insulated both from the inside and outside. But since you will be doing the work on your own, that is, without the help of specialists, it is better to resort to internal insulation.

Stage No. 1. Choosing insulation

There are a lot of thermal insulation materials on the modern construction market, but for balconies the following are more suitable:

As for foam plastic and EPS, the laying of these materials is carried out using almost the same technology (the only exception is the form of adhesion - with EPS it is better due to the use of grooves).

It is better not to use mineral wool for a balcony - the installation procedure will be more labor-intensive, and the condensation that inevitably forms on the balcony is undesirable for this material. Expanded clay, for obvious reasons, can only be used for floor insulation (the insulation technology will be described in detail below).

And if we add to all of the above the fact that the balcony should in no case be overloaded, then it becomes obvious: the most suitable option- this is foam plastic 4-5 cm thick, which costs less than polystyrene foam or mineral wool.

Stage No. 2. We carry out glazing

If your balcony is already glazed, you can skip this step. The glazing procedure itself largely depends on the parapet installed on the balcony. If we are talking about iron sheathing, then you must build it up using foam blocks or ceramic bricks. It is important that the resulting wall thickness exceeds 10 cm. And if you have a reinforced concrete parapet, you can immediately begin installing windows.

Today, many (especially fans of environmentally friendly building materials) prefer double-glazed windows with wooden frames. It is worth remembering that such structures need to be treated with an antiseptic and painted regularly. You can learn about installing double-glazed windows with wooden frames from the video below.

Video - How to install a wooden window with double glazing

However, the majority of consumers still buy PVC windows. When purchasing, choose a special plastic profile that is characterized by increased rigidity and strength characteristics. In addition, the profile must have good thermal insulation properties.

Plastic windows should also have:

5-chamber profile;
2-chamber (if you live in middle lane) or 3-chamber (if in a more severe climate) double-glazed window;
reinforced reinforcement.

After installing the PVC structure ordered according to the dimensions of the balcony (the work should be carried out by specialists), you can proceed directly to insulation.

Stage No. 3. We insulate the floor

Let's look at how to insulate a balcony from the inside with your own hands using polystyrene foam (although the technology described below is also suitable for polystyrene foam).

Table. Insulating the floor on the balcony

Steps, no.	Short description	Illustration
Step #1	First, prepare the working surfaces - seal with foam all the cracks found in the concrete, as well as at the joints between the slabs and the wall.
Step #2	Mark the floor for the subsequent construction of the sheathing. In this case, it is important that the pitch of the sheathing exceeds the width of the insulation sheets by approximately 10 mm.
Step #3	Lay the slats according to the previously made markings (the approximate size of the bars is 4x4 cm, but their width must correspond to the thickness of the insulating material). The first and last slats should be 50-100 mm away from the walls. Connect the slats using self-tapping screws.
Step #4	Place sheets of foam plastic between the lathing slats, gluing them to the floor liquid nails or special glue. Blow out any resulting voids with foam.
Step #5	Lay a vapor barrier layer on top of the insulation. Lay a vapor barrier layer on top of the insulation (necessary to increase thermal insulation and prevent the formation of condensation). If you use regular PET film, then under no circumstances place it on the “cold” side of the insulator. If you are laying foil insulation, then do it with foil to the foam.
Step #6	Fix sheets of plywood or chipboard on top, and the thickness of the floor covering should be at least 20 mm. Attach the sheets to the slats using self-tapping screws.
Step #7	All that remains is to lay the finishing coating, which can be carpet or linoleum.

Important information! There is another way to insulate the floor on a balcony with polystyrene foam: sheets of foam plastic are attached to a leveled and cleaned surface, and a thin screed from a previously prepared dry mixture solution is poured on top. Ceramic tiles can be used as a finishing coating here.

Alternative option. We use expanded clay

As noted earlier, the floor on the balcony can also be insulated using expanded clay. This material is also inexpensive, and its installation is not difficult. Let's get acquainted with the algorithm of actions.

Step #1. First, lay a waterproofing film on the floor with an extension of 10 cm to the walls.

Step #2. Place the beacons around the perimeter in increments of approximately 25 cm, being careful not to lean them too far against the walls.

Step #3. Fill the floor with a 15 cm thick layer of expanded clay and distribute the material evenly over the surface.

Step #4. Moisten the expanded clay with cement laitance (this is an aqueous solution of cement).

Step #5. Fill the expanded clay with a layer of concrete or self-leveling mixture. This must be done carefully so as not to damage the structure of the insulator.

Step #6. Wait for the screed to dry completely. After this, you can begin laying the topcoat.

Stage No. 4. We insulate the walls

The technology here is almost the same as for floor insulation. Follow these steps:

Step #1. Mark the future location of the slats on the walls (as well as for the floor).

Step #2. Attach the slats in accordance with these markings.

Step #3. Apply polyurethane foam to the surface using wave-like movements. At the same stage, you should drill holes for the dowels.

Step #4. Attach the foam sheets using plastic mushroom dowels.

Step #5. Blow out all the resulting cracks with foam, then seal with mounting tape.

Step #6. Lay a waterproofing layer on top - for example, penofol, which will also serve as thermal insulation.

Step #7. Seal the seams at the joints with foil tape.

Step #8. Mount the counter-lattice on top of the foam foam and install the finishing material.

Stage No. 5. We insulate the ceiling

This procedure is also performed using a similar technology, but some differences still occur.

First, make a marking along which the hangers for attaching the guides will be installed.
Install the hangers themselves necessary to fix the guides (for the latter, use a galvanized profile or timber).
In appropriate places, cut small holes in the insulator (foam or EPS) for hangers.
Next, secure the insulation boards using the same mounting foam.

If the insulation weighs too much, you can use dowels for fastening. Blow out the cracks with foam. Otherwise there are no significant differences.

Finishing features

In most cases, balconies are lined from the inside with clapboard or profile, but plasterboard is also used, followed by wallpapering. PVC panels are also used for cladding. Concerning exterior finishing, then it is better to entrust it to professionals, especially if your apartment is located higher than on the ground floor.

Important information! It is forbidden to take there central heating, so if additional heating is required, you can lay a film “warm floor” under the linoleum.

You can also install an outlet on the balcony to which an electric heater will be connected. The described room is small, so heating will take a minimum of time. We also note that the double-glazed window weighs quite a lot, so the remaining materials (including the insulator itself) must be of minimal weight. By the way, this is another reason why it is better to give preference to EPS or foam boards.

Video - Instructions for insulating a balcony

Now you know about the strong and weaknesses materials suitable for insulating a balcony, as well as technologies for laying polystyrene foam and expanded clay. Therefore, it's time to get to work! Moreover, there is nothing complicated here if you are armed with step-by-step instructions and all the necessary materials. If you do everything correctly, you will turn the balcony into a full-fledged living room with all the ensuing advantages.

The value of additional square meters in a city apartment is difficult to overestimate. A loggia can be a cold island for storing things or a warm room for living. But, in order for it to be fully used, care must be taken to ensure an acceptable temperature in this room.

It has become the main task for those who want to expand the usable area of the apartment.

The degree of insulation depends on the purpose of the room, as a living room or storage space.

And if the question of whether it is necessary to insulate the loggia has long been resolved, then there is still no consensus on the place of insulation.

Three directions for insulating a loggia

insulation of the loggia from the outside– the preferred option. In this case, the freezing point shifts to the outside, i.e. towards the insulation installed outside the loggia. This will not only insulate the surface of the wall, but also preserve the load-bearing properties of the material from which it is built. In addition, the internal space of the loggia is saved.
The only drawback of insulation from the street is the cost of high-altitude work (industrial mountaineering). For external insulation, rigid thermal insulation material (expanded polystyrene, polystyrene foam) is used, which is covered with a polymer mesh and protected with strong cement mortar and/or decorative plaster;

Note. In some cases, the decision on whether it is possible to insulate a loggia from the outside is determined by the City Council. For example, if a house is of architectural value, it is prohibited to carry out external work that changes the appearance of the building.

double-sided insulation and finishing of the loggia. Involves installation of thermal insulation material outside and inside the loggia. Such a solution is inappropriate in principle, because From the point of view of thermal efficiency, it does not matter which side the work is carried out on.

insulation of the loggia from the inside. Internal insulation is the most popular option, because... There is an opportunity to do the work yourself. However, in this case, the usable space of the loggia is reduced. Nevertheless, we will dwell on this option in more detail.

Do-it-yourself insulation of loggias - step-by-step instructions with photos

Simple technology for beginners without construction experience.

Step 1 – Determining the need for insulation

Depending on the future purpose of the room, a decision is made on whether it is necessary to insulate the loggia from the inside or outside, what type of insulation and what thickness will be used.

By definition, a loggia is a room in a building with one open side. This specificity allows owners to carry out insulation with lower financial costs compared to insulating a balcony.

The fact is that only one side will need to be insulated - the parapet of the loggia. As for the other sides, if they border the heated rooms of the apartment, there is no need to perform insulation.

Step 2 – Degree of insulation of the loggia

It is a mistake to think that glazing a loggia with double-glazed windows is sufficient. reliable way save heat in the room. In order to ensure the desired temperature in the room with minimal costs, you need to take care of the thermal insulation of all surfaces: walls, floors, ceilings. It is better to do the work simultaneously, but you can also do it in parts, the main thing is to follow the order.

Step 3 – Selecting insulation for the loggia

At first glance, the selection is not difficult. However, the variety of thermal insulation materials makes you wonder what is the best way to insulate a loggia from the inside.

penofol(40-50 rub./sq.m.). Belongs to the group of semi-rigid insulation materials. It is distinguished by the presence of two layers: foamed polyethylene and foil, which will serve as a reflector (reflects up to 97% of thermal energy). Insulating a loggia with penofol is more justified than insulating a balcony with it, but despite this, the use of penofol alone is quite rare;

Styrofoam(2560-3200 rub./cub.). Optimal price/quality ratio. It has excellent thermal insulation properties, is non-hygroscopic, does not require the use of films, and is easy to install. The market offers foam with different densities (15, 25, 35 kg/m3) and different sheet thicknesses - 20-100 mm, which makes it possible to vary the thickness;

expanded polystyrene(extruded foam plastic or penoplex) (3500-5000 rub./cube). Newer generation of foam plastics. While maintaining the advantages of polystyrene foam, it is distinguished by its high density (40, 100, 150 kg/m3) and a tongue-and-groove fastening system, which makes it possible to avoid cold bridges. Insulating a loggia with penoplex is one of the most effective methods of thermal insulation, but widespread use limits its cost;
Note. Insulating a loggia with polystyrene foam is advisable if you need to minimize space loss during the thermal insulation process.

cotton wool. Representative of soft insulation materials. Mineral (400-500 RUR/pack = 5.76 m2) or basalt wool (650-720 RUR/pack = 5.76 m2) are good because they make it possible to insulate a surface with uneven surfaces or cracks. The line of insulation of this type includes materials with different densities and prices. However, the general disadvantage of mineral wool is its susceptibility to moisture. This requires the use of waterproofing films;

polyurethane foam. Thermal insulating material that is sprayed onto the surface under pressure, allowing you to fill the smallest cracks. Work on insulating a loggia is carried out quickly, but is expensive;

expanded clay. Bulk insulation. It has significant weight and can only be used for floor insulation;

aerated concrete. Allows you to level the walls and insulate them, but the usable area is reduced.

With the exception of expanded clay and aerated concrete, each of the insulation materials can be used to insulate a loggia.

Factors influencing the choice of insulation:

technical condition of surfaces to be insulated: their configurations, the height of the floor/ceiling, the condition of the ceiling;

number of surfaces to be insulated. Often the wall adjacent to the room is not insulated;

climate. In regions with high humidity, it is undesirable to use soft insulation;

environmental friendliness. Polystyrene foam is considered the least environmentally friendly material, basalt wool - the most;

ease of installation. Rigid insulation is easier to install. When using them, you can do without forming a lath for laying soft wool. There is also no need to use films. In terms of installation, polystyrene foam has the best qualities, thanks to the tongue-and-groove system;

type of finishing coating;

cost of the project: insulation of the loggia on a turnkey basis or with your own hands.

Step 4 – Preparing materials and tools

For the work you need to prepare: thermal insulation material, polyurethane foam, primer, wooden beams (50x50, for the floor) and slats (50x30, for installing lathing under soft insulation), vapor and waterproofing film (for soft insulation), hardware, metallized tape, Decoration Materials.

Tools: hammer drill, drill, level, hammer, tape measure, foam gun, vacuum cleaner, stapler, pliers, pencil.

Note. Wooden beam can be replaced with a profile for plasterboard. The dimensions of the timber are determined by the thickness of the insulation.

Step 5 – Glazing the loggia

Glazing and insulation of loggias are two interdependent actions. When installing plastic windows, you need to give preference to a 4-chamber profile and a 2-chamber double-glazed window. During installation, you need to ensure the tight fit of all structures. It is obligatory to install a low tide outside to prevent water from flowing in. A window sill is installed inside, taking into account the thickness of the insulation.

Installing PVC windows makes it possible to increase the temperature on the loggia by 2-3 degrees compared to the temperature outside the window.

If it is not possible to replace old windows, they can be sealed. It is better to insulate loggia windows using Swedish technology. It makes it possible to increase the thermal insulation properties of windows without changing their functional characteristics.

Step 6 – Surface Preparation

Whatever type of insulation is carried out on the loggia, due to its small area, it must be freed from everything extraneous. It is for this reason that it is advisable to insulate the entire loggia at the same time.

Then the actions necessary for further work are performed:

removing protruding parts that can be dismantled;

punching and drilling walls. If necessary, electrify the loggia;

processing of elements that cannot be dismantled. The metal is cleaned and coated with a primer;

primer treatment of all surfaces of the loggia. This will prevent the development of fungus;

cleaning.

Step 7 – Insulating the floor on the loggia

It is advisable to start insulation work from the floor.

Regardless of the material, it is carried out using logs. An exception is when laying insulation followed by screeding under tiles or when installing a heated floor system. The work is carried out in several stages:

installation of penofol. This is not necessary, but experts advise laying penofol with the reflective side up. Due to the reflective ability of penofol, almost all the heat that comes from the wall adjacent to the room or from a heating source remains in the room;

installation of logs. Before installation, the timber must be cut to size and treated with a primer. The longitudinal beam is laid at a distance of 50-70 mm from the walls, and the transverse beam with a pitch equal to the width of the insulation (for foam plastic 500 mm, for wool and expanded clay - 600 mm). The beams are attached to the floor with dowels. When installing the joists, make sure they are fastened correctly; in the future, they will serve as a guide for arranging the floor and installing the finished floor covering.
Note. Installing joists close to the wall increases the risk of wood deformation if it gets wet.

installation of insulation. Rigid insulation is placed between the joists. When insulating a loggia with foam plastic or polystyrene, it is not recommended to use thick material. Craftsmen advise purchasing thinner sheets and laying them offset. This minimizes the surface of cold bridges. Cotton wool is also placed between the joists so that the material is laid freely, without knocking down. A vapor barrier film is placed on top of the wool to prevent it from getting wet.

seam sealing. If rigid insulation is laid with gaps, they need to be blown in with polyurethane foam, which is a good insulator.

arrangement of the subfloor. It is not recommended to lay laminate or linoleum until the work is completed. If the floor is finished with tiles, it is installed immediately and protected (covered) with cardboard.

Note. Using a heated floor system will ensure heating of the loggia, because it is prohibited to remove central heating radiators, and the use of a heater does not provide a long-term effect.

Step 8 – Insulating the ceiling on the loggia

This stage can be eliminated if the floor of the neighbors above is insulated. If not, then the simplest solution would be to insulate the loggia with polyurethane foam. It adheres well to any surface, and the work can be completed in a day.

Often, the insulation of the ceiling on a loggia is done with rigid insulation, or less often with cotton wool. The order of work may vary.

Option 1 - frame method of thermal insulation of the ceiling on the loggia

installation of penofol. From physics course we know that warm air rises. And in order not to heat the floor of the neighbors above, it is advisable to install penofol on the ceiling;

arrangement of the frame. For work, wooden slats are used, with a thickness equal to the thickness of the insulation;

the insulation is placed in the cells of the frame. If cotton wool is used, a vapor barrier film is additionally installed;

performed finishing ceiling.

Option 2 - “wet” method of insulating the ceiling on the loggia

If the base of the ceiling is flat, you can glue rigid insulation to it. Additional fixation will be provided by the use of dowels with a large head. The junctions of the insulation sheets are foamed with foam. For additional effect, penofol is installed.

Option 3 – insulation of a suspended ceiling on a loggia

Place insulation (usually cotton wool) on the finishing material of the ceiling. Suitable for suspended ceiling or finishing the ceiling with laminate or plastic panels.

Step 9 – Insulating the wall on the loggia

Insulating the walls of the loggia is the easiest step. However, it has an important feature, namely: the walls of the loggia are insulated in different ways.

the wall adjacent to the room is insulated in one layer;

the outer wall is insulated in two layers or a thicker thermal insulation material is used. Moreover, it is laid in pieces, and always with an offset.

Similar to work on the ceiling, there are two methods of insulation: “wet” and frame:

"wet"– suitable for rigid insulation and the only one possible for aerated concrete. Often this method is used to insulate the loggia with penoplex.

frame– required for soft materials. Without a frame, it is impossible to insulate a loggia with cotton wool. The frame can be made of wood or metal profile. The technology for laying wool on a wall is no different from installing it on a ceiling or floor. The protection of the cotton wool is ensured by the installation of the film.

Many residents apartment buildings are faced with the problem of a shortage of square meters. Great solution This issue can be solved by insulating the loggia yourself. This is a painstaking task that requires the performer to have certain construction skills and time. However, the finished result is worth it. A warm balcony expands the possibilities of using space, “ennobles” the living space and can become a source of pride for a home craftsman.

The need to insulate the loggia

Each apartment owner decides for himself how to use additional square meters loggias. Some set up a storage room or workshop on the balcony, others use the premises more rationally - create “ winter Garden" or separate room. An insulated loggia can be converted into a cozy place for relaxation, work, a compact gym or an area for children's creativity.

In addition, an insulated balcony solves a number of problems:

heat loss from the premises and heating costs for the apartment are reduced;
reduces the risk of mold on the walls of the balcony.

You can perform external or internal insulation. Obvious advantages of the external method:

the usable area is not “eaten up”;
simplification of interior wall decoration.

A significant advantage of internal insulation is the ability to do the work yourself without hiring workers.

Selection of thermal insulation material

Various thermal insulation materials are used as insulation, ranging from traditional, inexpensive ones to modern high-tech ones. To insulate the loggia from the inside, it is better to use thin, lightweight materials. Thanks to their small width, you can save useful space.

Let's consider the characteristics of the main thermal insulation materials for insulating a loggia/balcony.

Foil polyethylene foam - a layer of foil is applied to one side of the polyethylene, which reflects IR radiation and “rejects” heat flows back. Insulation characteristics:

roll width - 1 m, thickness - 2-5 cm;
ease of installation - polyethylene foam can be easily cut with a knife;
laying method - butt or overlap;
thermal insulation efficiency almost doubles;
the material is used to insulate ceilings and walls.

Insulation of the loggia: step-by-step instruction. Use of penofol

Mineral wool has good thermal insulation qualities and an affordable price. However, experts do not recommend using this material to insulate a loggia for a number of reasons:

poor moisture resistance - mineral wool absorbs liquid, so you will have to further strengthen the waterproofing;
when using mineral wool, natural ventilation is required - a gap must be left above the insulation, which slightly “conceals” the area of the balcony;
To cover the loggia, you will need to reinforce the wall and carry out additional measures.

Foam plastic is foamed plastic of varying densities. The bulk of the material is gas. Polystyrene foam has the following characteristics:

slab size - 1*1 m;
insulation thickness 2-10 cm;
foam density - 15 or 25 kg/sq.cm;
durability.

Extruded polystyrene foam (penoplex) is a modern heat insulator that resembles polystyrene foam, but has a more durable structure and functionality. Properties of expanded polystyrene:

rectangular slabs 1200*600 mm;
thickness - 2-10 cm;
penoplex density - 35-45 kg/sq.cm;
vapor tightness;
frost resistance;
the slabs are chamfered for tighter installation;
light weight and ease of installation;
flammability class - G-1;
the material is not used in open areas where UV rays penetrate.

Methods for attaching insulation

The choice of insulation method primarily depends on the heat-insulating material used and further finishing of the walls.

Insulation under putty and plaster is suitable when using penoplex or polystyrene foam. Thermal insulation panels are glued to the base with tile adhesive. The slabs are additionally fixed with dowel mushrooms. You can start plastering/puttying walls or ceilings the day after installing the insulation.

Laying of foil polyethylene foam occurs under the base of the frame. It does not matter how the profiles are attached - to the wall or using U-shaped fasteners. Penofol sheets are applied to the ceiling/wall of the loggia and fixed with slats. In this case, an overlap connection is permissible, and the joining strip can be glued with tape.

Insulation under the base of the frame is only possible when using thin insulation up to 20 mm thick. Pressing thicker thermal insulation will affect the rigidity of the slats and fastenings

If you plan to cover the balcony with plasterboard or PVC or MDF panels, then it is advisable to lay the heat-insulating material in the cells of the frame. 15-density foam or mineral wool is used as insulation. The disadvantage of this technology is the increase in the thickness of the thermal insulation “pie”.

Options for arranging a “warm” floor

The technology for insulating the floor on a loggia is somewhat different from the thermal insulation of the canopy and ceiling. Excessive demands are placed on this element of the balcony.

There are several main options for arranging a “warm floor”:

Preparatory work

First of all, you need to install energy-saving plastic windows on the loggia. There is no point in saving on glazing - it is better to choose double-glazed windows and fittings from companies that have proven themselves in the window market.

If high-quality windows have already been installed on the balcony, then you can proceed to insulating the balcony.

Preparatory activities:

Ceiling insulation

Installation of heat insulator on walls and parapet

Let's consider the stages of creating a “warm floor” using penoplex and cement-sand screed:

If installation is required load-bearing frame It is better to use galvanized metal profiles. Unlike wood, it does not rot and is not heavy.
Thermal insulation work should be carried out in dry weather. Many adhesive mixtures and primers have specific features for use in conditions of high humidity.
The cracks in the loggia are treated with foam that is resistant to low temperatures.
The wood used must be dried and then treated with anti-fire and rotting agents.

The first association that arises when we hear the word balcony is cold small space outside the window, where we take out everything that seems to be unnecessary, but it’s a shame to throw it away. This is not surprising. More recently, the balcony was invented as an additional room to the apartment for drying clothes and storing vegetables. But in last years the situation has changed dramatically, and now the balcony is becoming part of the interior of the entire apartment, and can perform several useful functions both in summer and winter. "But how is this possible?" - you say. Very simple. Nowadays, balconies are insulated, sheathed, energy-saving windows are installed, and even heated.

Let's consider the best way to insulate the balcony of an ordinary apartment

There are two options for insulating balconies: outside and inside. Both of these methods are radically different from each other. If in the first case the balcony is insulated without affecting the internal space of the already small balcony, then in the second, its usable area is reduced by at least 30-40 cm. For large balconies this is hardly noticeable, but for loggias with small dimensions this insulation technique is not entirely suitable. "So what's the deal! – you say, “let’s insulate all the balconies from the outside.” The idea, of course, is good, but there is one “but” in it.

What is the best way to insulate a balcony? What methods and types of materials for insulating balconies exist in general, and how to properly carry out insulation. Our experts will try to answer these questions.

You can only insulate a balcony from the outside with your own hands if it is located no further than the second floor. To work at higher altitudes, you need to resort to the help of professionals, which will cost a pretty penny. Therefore, it is cheaper, after all, to insulate the balcony from the inside. Moreover, many special materials are sold for this.

Materials that are suitable for insulating balconies inside:

Styrofoam;
Penoplex;
Penofol;
Mineral wool;
Expanded clay;
Izolon;
Polyurethane foam.

Each of the materials has its pros and cons, but they are all excellent for insulating balconies and loggias from the inside.

You can learn about the characteristics of other materials, as well as the stages of insulating a balcony, from our article: https://homeli.ru/komnaty/balkon/uteplenie-balkona.

The best way to insulate a balcony inside: finishing methods

There are many ways to insulate a balcony. When choosing your option, be guided by your personal plans. Based on what functions you want to provide your additional living space in the future. Modern technologies Nowadays, it is possible to install energy-intensive windows, insulate facades and walls with such materials that the cold will not penetrate into the room at all, and heat will not be able to escape outside.

The better to insulate the balcony inside, if you do major renovation? Based on your financial capabilities. From budget materials The most popular material for insulating a balcony is polystyrene foam. It is lightweight, fully meets the requirements for insulation and does not deteriorate for a long time.

The quality of insulation, for the most part, is influenced not by the material with which you plan to insulate the balcony structure, but by the method of insulating it. The more part of the structure you insulate, the better the thermal insulation will be, and the warmer the balcony space will be in winter. If it is additionally equipped with heating, then such a balcony can be used all year round without feeling the cold outside the door.

What methods can you use to insulate a balcony from the inside:

Insulate the walls;
Cover the floor with insulation;
Lay insulation on the ceiling as well;
Line the entire perimeter of the balcony with insulation;
Add floor heating to a fully insulated balcony.

In addition, while performing work, you can add additional methods of insulation such as a gasket made of foil sheets, or a wind barrier made of polyethylene film.

Let's find out how to install insulation for a balcony indoors

After we have decided on the material for insulating the walls and the method of performing the work, we need to draw up a plan for subsequent actions. It should consist of construction stages and task completion periods. Once again, evaluate the capabilities of your balcony. If you are not yet equipped with energy-saving windows, now is the time to install them. You are doing a major overhaul of the sheathing, and later it will be difficult to return to it, and installing plastic windows will require strengthening the positions that support them.

Insulation for the balcony inside the space must be prepared in advance. Try to calculate the quantity correctly consumables. This is not difficult to do; you just need to carefully calculate the area of the insulated planes.

Next, step by step, according to your own plan and studying reviews from experts, move forward. Immediately think about how you will decorate the walls of your balcony. The method of laying insulating material during further cladding of the balcony with clapboard or plastic differs from insulating a balcony without further cladding.

Step-by-step instructions for insulating a balcony:

If you already have windows installed, then we start by sealing cracks, cracks and damage. Wood paneling check for rotten boards and fungi. If they exist, then take measures to eliminate them. If there are no plastic windows, then you need to install them.
If you will later cover the balcony with clapboard (which is done very often), then you need to start arranging the sheathing.
Think about electrical wiring. Do the wiring in advance so you don’t have to mess up the repair later.
We begin the insulation process. Place insulation in the space between the sheathing beams, attaching it in accordance with the type of material.
Seal the gaps between the insulation if it is solid.
Seal the joints with mounting tape.
For greater thermal insulation, place a layer of foam foam on top.
Level the surfaces.
Cover the walls with finishing material.

When carrying out work on the balcony, one rule should be taken into account - to repair the balcony, choose the lightest finishing materials. The balcony is a special design and should not be overloaded.

Practice shows that it is best to insulate balconies from the inside with penoplex and penofol. It is better not to use mineral wool for this. Although it is soft and comfortable, it does not like dampness. And temperature changes on the balcony are inevitable, therefore condensation is also inevitable.

What is the best way to insulate a balcony from the inside if you don’t have a lot of money? Use foam. It is not expensive, but quite practical material. A balcony properly insulated with it will serve you for a long time and reliably.

Foam plastic, 4-5 cm thick, will be quite enough to insulate the walls of the balcony. Use liquid nails or special glue as an adhesive material. Do not use heavy mixtures for gluing. To ensure that the repair progresses in stages and the finishing materials do not interfere with each other, perform the work in a certain sequence.

Stages of work on insulating a balcony:

Install plastic windows;
It is best to start insulating a balcony from the ceiling;
Having finished it, go to the floor.
Lastly, the walls are insulated.

If you do everything correctly, then in the end your renovation will come together into one harmonious idea.

When renovation work on the balcony are completed, you can start arranging it. If this part is on the sunny side, it is necessary to hang curtains. You will find options and solutions in our next material: https://homeli.ru/dekor/shtory/shtory-na-balkon-idei-i-foto.

What your balcony will look like after insulation depends only on you. Apply maximum skill, patience and time, and you will equip yourself a wonderful room where it will not be hot in summer and cold in winter.

We choose modern materials that are suitable for insulating the loggia from the inside

To create a comfortable functional room in the loggia, it is necessary to carry out work on its high-quality insulation. On the market today there are the most different materials, therefore, it is possible to insulate the loggia with mineral wool, expanded polystyrene, polystyrene foam and other types of insulation. The choice of insulation depends on many factors. It is very good if you have the opportunity to consult with specialists on this matter.

Mineral wool

Insulation with mineral wool is the traditional and most common option.

This material can provide a fairly high level of thermal insulation and sound insulation.

At the same time, it is recommended to use mineral wool for insulation only if there is no load on the insulation. Besides, insulation material It is necessary to protect it as best as possible from exposure to moisture and the formation of condensation on it.

Mineral wool insulation work is carried out in the following sequence:

First, all surfaces insulated from the inside are waterproofed. This stage is preliminary. To create a high-quality waterproofing layer before insulating the inside with mineral wool, it is best to use special insulating impregnations. They can be bitumen and polyurethane mastic, special paints and varnishes. In addition, rolled polyethylene materials (sold at any hardware store) are often used as an insulator. What kind of insulator will be used is not particularly important.
Then you need to install the sheathing. The installation step of the wooden blocks should be approximately 1 cm less than the width of the mineral wool sheets. In addition, you need to select the bars so that their thickness is slightly greater than the thickness of the slab of heat-insulating material. The sheathing elements can be fastened to rough surfaces using dowels and self-tapping screws.
To install mineral wool slabs, you need to select and dilute a suitable adhesive composition (which one is not important). It is applied to the surface of the slab from the inside, after which it is placed in the cell formed by the sheathing. The slabs need to be adjusted so that they are slightly larger in size than the dimensions of the cell. This will avoid unnecessary voids.
As soon as the adhesive composition has dried, it is recommended to additionally secure the heat-insulating material with your own hands using mushroom dowels.
Surface finishing can be done using any suitable materials. Any type of finishing that will not create a large load is suitable for this - plastic panels, plywood sheets, lining...
Finally, surface finishing and decorative work are carried out. In this case, the work can be done with any finish.

ISOVER material gives good results and reviews.

Expanded polystyrene

Insulating your loggia inside with polystyrene foam gives fairly good results. This material is produced by mixing polystyrene and special foaming components. The mixture is heated, subjected to high pressure, then foamed and carbon dioxide added.

To insulate a loggia with polystyrene foam, slabs 45-50 mm thick are perfect.

They are fastened using dowels, double-sided tape and glue (which type of fastening to choose depends on the material of the walls). When insulating a loggia from the inside with polystyrene foam, it is best to place the material slabs in a checkerboard pattern so that they do not move under their own weight during operation.
To prevent the occurrence of cold bridges, seams, gaps and joining areas must be filled with your own hands. construction foam(when insulating with expanded polystyrene and polystyrene foam, the problem of cold bridges is especially relevant).
As soon as the polyurethane foam has dried, you need to cut off the excess with your own hands.
To provide additional insulation, which is required when insulating with expanded polystyrene and polystyrene foam, it is imperative to lay a layer of special foamed polyethylene 5-8 mm thick. In this case, the layer with foil should be located inside the loggia. This approach will allow you to create a high-quality vapor barrier layer with your own hands and ensure heat reflection. The seams must be taped with construction tape yourself.
You can attach a wooden sheathing to the heat-insulating layer (for this it is better to use small-sized bars that have been pre-treated with antiseptic compounds). In addition, instead of lathing from the inside, the loggia is often finished with plasterboard sheets.
Any finishing materials can be applied to wooden lathing or plasterboard sheets with your own hands.

You can do without sheathing and use mesh for reinforcement, under finishing.

Penoplex and penofol

Very often, penoplex and penofol for insulation are used in one insulation system.

One of the best materials.

These are high-quality insulating materials that have a lot of positive performance and technical characteristics. Many experts recommend using them specifically for insulating loggias from the inside. Using such insulation for a loggia will create a comfortable environment inside the room and maintain an optimal microclimate on the coldest days.

Penofol for loggia.

Insulation work using these materials is carried out in the following sequence:

First, you prepare all insulated surfaces with your own hands: floor, ceiling, walls, parapet. The old finishing material is completely removed, all traces and debris are removed. After this, you need to carefully check the integrity of the structures from the inside to ensure that there are no cracks, holes or other defects through which cold air can penetrate into the room. It is important that the loggia is completely sealed on all sides.
Then, vertical logs are installed. The material must be fastened in a certain increment, the size of which will depend on the thickness of the insulation used.
Next, penofol is attached directly to the joists. For this you can use any suitable adhesive compositions, which are suitable for indoor use. During the installation of the initial layer of penofol, it is necessary to direct the foil outward.
After this, penoplex is installed (the best option for a loggia is material with a thickness of 20 - 25 mm). Laying slabs from the inside of the loggia can be done independently - there is nothing complicated in this process.
Finally, you need to glue another layer of penofol. In this case, the material must be positioned so that the foil layer is directed inward. As a result, we will get a kind of pie in which the main thermal insulation material (penoplex) will be protected by penofol on both sides.
All joints that arose during the installation work from inside the loggia must be glued with construction adhesive tape.

What thermal insulation material should I choose to insulate my loggia?

You need to understand that work on insulating a loggia with your own hands can be done from the inside and outside. Of course, it is much easier to do insulation inside the loggia. For this purpose, a variety of different thermal insulation materials. Their choice will depend on the design features, operating conditions, and the nuances of installation work, so in each case, special attention must be paid to the choice of insulation.

It will not always be justified to purchase the most expensive insulation on the market.

For example, if the loggia has high-quality glazing, high-quality construction, and no defects are observed, then you can use the most simple materials. In addition, the choice of insulation for the loggia will depend on whether heating is planned.

The best way to insulate a balcony inside: what materials to choose

If your apartment or house has a balcony, then you should definitely use it, since it is an additional, and sometimes simply necessary, area. If you approach the issue with imagination and think through all the nuances, you may end up with a small, but very cozy room. In order for a balcony to serve as a room, it must be insulated. How to insulate the balcony inside is decided by each owner independently, taking into account his financial capabilities and pressing needs. But a few words should be said about the nuances of the process and the materials used to insulate the balcony. You need to choose these materials very carefully and pay attention to all the characteristics.

Where to begin

You need to start mastering any balcony with an objective assessment of its condition. If the apartment is located in a new building that has recently been handed over to residents, then you need to pay attention to the material from which the balcony structure is made. Also, in new houses, you need to pay attention to what the neighbors’ balconies are decorated with. Often in such houses neighbors try to adhere to the same style.

We make masonry from foam blocks

But if the balcony is in a far from new apartment and has always been used as an open space, then work will have to start with strengthening the balcony. Strengthening includes both the reconstruction of the concrete balcony platform and the strengthening of the metal handrail. Also, this process may include such an event as strengthening the lower part of the upper balcony; this must also be taken into account. After solving all these issues and choosing the material for the outer cladding of the loggia (balcony), you can move on to interior decoration. To simplify this stage, you can lay a wall of bricks or foam blocks up to half of the balcony, directly to the double-glazed windows. This will save on insulation.

Advice: If all stages of insulation are carried out at the same time, then it is better to immediately install them in the windows double glazing, since one glass gives 70% more heat loss in cold weather.

Preparing for insulation

To begin insulating the inside of the balcony with any materials, you need to make preparations. Having chosen the material for insulation, you need to create a special wooden sheathing under it, on which it will then be attached. The exception is rolled materials that can be mounted under the sheathing. This frame is made of beams with a cross-section of about 4-5 cm. Transverse and perpendicular beams must be fastened so that squares of 50 by 50 cm are obtained. The sheathing can also be made of a metal profile, but this material is somewhat more expensive than wooden beams. The main advantages of a metal frame are lightness of construction and ease of use.

Note: When calculating the required insulation for a balcony inside, you need to take into account not only the dimensions of the walls, but the floor and ceiling, since these two positions also need insulation.

Material selection

Insulation is placed in the sheathing on the inside of the balcony, which can be:

Foam insulation is one of the most common methods of thermal insulation of balconies and loggias

Styrofoam. The cheapest of these materials is simple white foam, 5 cm thick. If you are insulating a room in cold latitudes, you can take thicker polystyrene foam; it can reach a thickness of up to 10 cm. It can be easily cut into required amount parts, and you can not additionally strengthen them with anything, but immediately lay them in the cells of the sheathing under the finishing materials. The material is absolutely safe both when working with it and during subsequent use. The insulation is completely odorless and does not emit toxic substances, and styrene vapors in small quantities do not affect human health. Installation of the material occurs without the formation of dust.

Insulation with mineral wool

Mineral wool. Mineral wool is a little more expensive, but its sound insulation properties are much higher, so if you need to get rid of extraneous sounds, it is better to use it. This material is completely natural and completely fireproof. The combustion temperature of mineral wool starts from a thousand degrees. The inconvenience of laying mineral wool briquettes lies in the mandatory compliance with safety precautions. The material contains small glass particles that cause itching of the skin. Installation must be carried out in protected special clothing, safety glasses and a respirator.

Expanded clay. The material is an environmentally friendly insulation material. The word “expanded clay” is translated from Greek as “burnt clay”. The material is often used for insulation of floors and ceilings. It is not entirely profitable for them to insulate the walls, since they additionally need to prepare a metal mesh as a support.

After insulation, you will need to move on to the interior decoration of the balcony. Plastic panels are well suited for these purposes. Read more about them and their differences in this article.

Installation of high-quality double-glazed windows plays a big role in insulating a balcony or loggia. Which window profile choose? - you will find the answer here.

Penofol. This material is one of the thermal insulation products that has a reflective effect. It is a layer of foamed self-extinguishing polyethylene with closed air pores. Coated with high quality aluminum, 14 microns thick and 99.4% pure on one or both sides. Penofol is a universal material with steam, hydro, wind and sound insulation properties. The material has the appearance of a thin, flexible, light and environmentally friendly structure. Foiled penofol can be used as an additional vapor barrier; it is very convenient to work with, since it is sold in rolls and is easy to cut even with ordinary scissors. This material protects the room from external moisture and eliminates condensation from the room.

Penoplex. It is a new material specially designed for room insulation. The material is very convenient to install due to its light weight, so its use on the balcony is now relevant. It is produced in the form of rectangular slabs of different thicknesses, which are easily cut with a stationery knife. It is also possible to produce “sandwich panels” using the casting method. Insulation with a rough surface allows them to be easily attached and glued to other materials.

Izolon

Izolon. It is also a universal material in terms of use. Confirmed safety for use as insulation and vapor barrier element. Excellent soundproofing characteristics.

The degree of thermal conductivity compares:

with 15 cm brickwork
with 4.5 cm wood
with 4.5 cm mineral wool
with 1.2 cm polystyrene foam

Reduces noise by at least 18 dB.

These are the main materials for creating an insulating layer, which are now easy to find in any hardware store. We hope you now have more information about How can you insulate a balcony from the inside?, and then we’ll look at how to do this.

How to insulate

One of optimal methods laying of insulation is layer-by-layer laying:

First, the surface is waterproofed
The next layer is the selected insulating material, which is also secured with appropriate fasteners. These can be nails, screws, plastic fasteners with wide heads.
Then a vapor barrier is laid, which is secured with a construction stapler.
At the final stage, finishing material is attached to the sheathing using special fastening materials.

Sheets of foam plastic are installed in the sheathing, and the joints are covered with polyurethane foam

The result should be a layer approximately 60 - 70 mm thick, this is the distance from the outer layer to the finishing layer. Depending on climatic conditions, this size may vary. You must understand that any layer of insulation requires financial costs and labor, so it is better to immediately build a balcony conscientiously and not try to save on trifles.

In a situation with insulating the floor on the balcony the sequence is also the same. If it is decided to fill the floor with concrete, then expanded clay is laid first and the solution is distributed on top of it. The concrete solution must be carefully distributed using a special rule and try to make the surface as smooth as possible. Then ceramic tiles or other finishing materials can be laid on such a surface. Under the final finishing, you can lay rolled heated floors, and this will give additional insulation premises.

Find out more about how to raise the floor on a balcony with your own hands and what materials you can use to do this.

Read about how to choose an electric heated floor. Features of different models.

If you choose the option of a wooden floor, then guide logs are first laid, between which the insulation is laid. Then a finishing board or chipboard is laid on the logs. Laying chipboard is necessary if laminate or linoleum will be installed further. It is also worth noting that under the laminate it is necessary to lay special substrate which will provide additional thermal insulation. When the finishing of the walls and floors is completed, skirting boards are installed to hide the joints of the finishing.

In the complex of works on insulating a balcony, it is necessary to pay attention to the ceiling. The insulation process is carried out according to the same scheme as walls and floors. The task will be complicated when the balcony or loggia is on the top floor and there is no ceiling. In this case, you need to take into account the additional costs of installing the ceiling and roof.

When working on insulating a balcony, you should not fuss and rush, this can lead to unreasonably high consumption of material. If you approach the matter carefully and carry out constant calculations, you can acquire a full-fledged additional room for little money.

How to insulate a balcony from the inside video

We invite you to watch a video on the topic of our article “Insulation for a balcony inside - choosing materials,” which shows in detail the entire process of insulating a balcony using penoplex and penofol.

How to insulate a balcony with your own hands: from a refrigerator to a warm island

To begin with, it’s worth saying that there are two ways to insulate a balcony – from the inside and the outside. External insulation, of course, is more convenient - precious centimeters of space are not “eaten up”, and the cladding of the balcony facade becomes more pleasant. But this is a labor-intensive process that requires the involvement of a construction team and industrial climbers. Therefore, in this article we will focus on how to properly insulate a balcony in an apartment from the inside - you can do this yourself.

To insulate the inside of the balcony, you first need to carry out preparatory work. They include several important steps:

Where to start insulating a loggia or balcony? Free up space from everything unnecessary. It’s best if the balcony is completely empty: it’s much easier to work this way. Also, get rid of old trim in advance.
Seal all the cracks - a lot of heat escapes through them. For small gaps, a weather-resistant sealant is suitable; fill larger ones with polyurethane foam - it will not only fill the voids, but will also serve as an additional heat insulator.
To make it easier for you to carry out insulation work, it is important to smooth out cracks and irregularities in the walls and ceiling using cement mortar.
If you plan to place light bulbs or lighting, it is worth taking care of the wiring in advance. To hide unsightly cables, place them in plastic boxes.
Before starting work, cover the opening between the balcony and the adjacent room with film to prevent construction dust and other pollutants from entering the apartment.

Is it possible to insulate a balcony in winter? Yes, you can. Only when carrying out work in winter is it necessary to choose frost-resistant materials, in particular polyurethane foam.

How to insulate a balcony: what materials are best to choose

To understand how to insulate a loggia or balcony, let’s first figure out what properties the materials should have:

high strength;
fire safety;
water resistance;
environmental friendliness;
relatively low cost;
ease of installation (if we want to do all the work ourselves).

Most often, mineral wool, polystyrene foam, polystyrene foam, etc. are used for insulation. Sometimes several of these materials are combined. We have reflected the pros and cons of each heat insulator in the table:

Which insulation for a balcony is better? The answer to this question depends on your preferences and financial capabilities. You can read more about the characteristics of insulation materials, as well as about insulating an apartment in general, in our blog.
