How to insulate walls brick bath from the inside? The inner surface of the walls It is most effective to insulate a brick bathhouse using natural heat-insulating materials that retain heat excellently, but do not emit heat at all. high temperature any harmful substances. In particular, mineral wool-based canvases, produced in the form of rolls or individual mats, are perfect for these purposes.

The only one disadvantage of such insulation– the ability to absorb moisture, which by definition is always abundant in any bathhouse. Therefore, the heat-protective layer will require additional waterproofing to protect the mineral wool from steam and water.

Installation procedure for insulation on interior walls will be as follows:

a load-bearing frame is erected on a brick wall from wooden slats;
The resulting cells are filled with thermal insulation material. In addition to mineral wool, more can be used here with great success. modern materials. For example, foil penotherm is not only absolutely insensitive to moisture and temperatures of several hundred degrees, but due to the shiny surface of the foil it is able to reflect heat back into the bathhouse;
the entire structure is covered with a layer of waterproofing (polyethylene, foil, etc. To ensure complete moisture resistance, waterproofing material should be laid with an overlap of 10-20 cm. To give the joints additional strength, all joints should be secured with thin and flat wooden slats.

To improve aesthetics, the insulation is usually covered rather than left open. wooden clapboard.

In addition to the walls, the internal thermal insulation of a brick bath should include measures to reduce heat loss through floors. The sequence of actions here will be as follows:

a layer of vapor barrier is laid on the subfloor, cleaned of dust and dirt;
heat-insulating mats are lined and fixed in one way or another;
a layer of waterproofing is laid;
a finished floor is installed from the maximum wide boards thickness of at least 40 mm.

It is very important to consider the material from which the subfloor is made. If it is formed by boards, then they will be required in advance treat with a wood rotting agent.

The concrete subfloor itself can play the role of thermal insulation. Therefore, even at the stage of its arrangement, care should be taken to impart heat-saving properties. This is achieved as follows flooring technology:

a layer of sand about 5-10 cm thick is poured into the pit and compacted;
a solid heat insulator (foam plastic) is laid;
a mixture of cement, sand and crushed foam is poured in;
roofing felt sheets are laid overlapping;
lined reinforcement mesh;
a concrete solution is poured with the addition of fine crushed stone;
at a height of 10-20 cm a finished plank floor is created.

The resulting design is advantageous in that it is ventilated. And this means a significant increase in the service life of both the finished floor and the heat-insulating concrete base under him.

Thermal insulation of walls from the outside

External work on thermal insulation of a brick bath are carried out using the same mineral wool insulation, which retains heat well, is non-flammable and can act as a sound insulator. If roll insulation is used, the easiest way to fix it on the external walls is with wooden planks or slats.

When application of thermal insulation in the form of mats based on mineral wool, the technology for performing the work will be slightly different:

a sheathing is constructed from a metal profile and corners, attached with dowels to the outer surface of the wall;
the cells of the sheathing are filled end-to-end with heat-insulating mats;
the joints between the mats are glued with construction tape for strengthening;
a layer of waterproofing is applied.

The final stage will be wall cladding decorative materials (siding, lining, etc.)

Meanwhile, it is quite possible to use foam sheets to insulate brick baths. Procedure for insulating a bathhouse with foam heat-insulating material will be like this:

the surface of the brickwork is freed from all types of contamination;
possible flaws in the form of chipped bricks or deep seams are carefully plastered;
sheets of foam plastic are glued to the wall using glue;
After the glue has dried, the foam plastic is additionally secured with special dowels with wide heads. The dowels should be screwed in at five points on each foam sheet: a few centimeters from the corners and in the middle;
the joints between the sheets of heat insulation are coated with glue;
reinforcement mesh is applied and fixed;
the resulting surface is plastered.

To give the wall extra strength plastering is best done in two layers.

Ceiling insulation

If the insulation is of poor quality, up to a quarter of all heat can escape through the ceiling produced by the furnace. Therefore, to reduce losses, no less attention should be paid to ceiling insulation than in the case of walls. The most suitable insulating material for these purposes is lightweight and non-flammable fiberglass.

Ceiling insulation work in a bathhouse are produced as follows:

fiberglass sheets or mats are laid out on the ceiling boards;
a mixture consisting of equal parts of sawdust, sand and clay is poured on top. Optimal thickness this layer – 20-25 cm;
after the previous layer has dried, sheets of foam plastic are laid out on it;
the entire surface is filled with a small layer of cement screed.

In addition, ordinary expanded clay. With a backfill thickness of about 30-40 cm, it will be able to reliably retain precious heat.

How to insulate a steam room

Insulating a steam room in a brick bathhouse generally differs little from creating thermal insulation in the remaining rooms of the bathhouse. The only differences are the need for additional thermal insulation of the ceiling inside the steam room, as well as the use of metal foil both on the ceiling and on the walls.

Procedure for insulating the ceiling in a steam room will be next.

The entire surface of the ceiling is covered with rolled paper. At the joints you need to create overlaps of 10-20 cm.
Nailed to the ceiling wooden blocks with a cross section of 5x5 cm. These bars will have a dual purpose: they will fasten the paper and become the basis for fastening the outer covering.
The entire ceiling is sealed with metal foil. To attach it, it is best to use a special duct tape, on one of the surfaces of which a layer of aluminum is applied. There should be no gaps between the sheets or strips of foil, since penetrating hot steam will cause the ceiling to become wet. This is fraught with deterioration in thermal insulation qualities and can lead to the development of putrefactive processes.
Stuffed on top of the bars wooden slats, to which, in turn, the main ceiling covering from wooden lining.

The foil is attached to the wall surfaces in the steam room in a similar way.

It is best to use it as a covering material in a steam room. pine clapboard. Pine perfectly withstands both high temperatures and the effects of hot steam from the heater. In addition, due to the presence of a certain amount of resins, distillation from pine will give the atmosphere of the steam room a special aroma.

In general, the process of insulating a brick bath does not cause any particular difficulties even for craftsmen without extensive experience in such work.

The most important- choose suitable insulation resistant to high temperatures and high humidity. In the case of using thermal insulation that is afraid of moisture, it should be carefully isolated from the bath atmosphere or from precipitation in the case of external work.

Insulating a brick bathhouse from the inside will not solve all the issues regarding heat preservation. This complex work, which involves insulating all planes.

After all, heat leaves the room in large volumes through the ceiling, and cold is also perfectly drawn through the floor. Therefore, today we will consider the question of how to insulate brick bathhouse most optimally and efficiently.

Also in the video in this article you can watch the entire process of doing the work and understand what and how to do.

We carry out insulation

Let’s now look at how to insulate a brick bath in more detail. Everything in this matter can be done with your own hands and without outside help.

Then the price of the work will be significantly lower, and you won’t have to worry about the quality. Below are instructions on the rules for performing this work.

Key Stages

The insulation of a brick bathhouse from the inside and outside is done according to a certain scheme and has already been worked out and time-tested. First of all, you should minimize heat losses bathhouse premises.

So:

Particular attention should be paid to insulating the steam room, the air temperature in which depends only on your personal preferences. The average temperature in this room varies from 60 to 130 degrees. As for the Russian bath, in which heat is “caught up” with hot steam at high level humidity in the bathhouse, then here you can limit the temperature to 60-90 degrees.
The temperature in the bathhouse should be maintained as high as possible for as long as possible. Maintenance desired temperature in conditions of large heat losses, it will require a huge amount of fuel and effort from you, which can ruin your vacation.
Moreover, due to heat losses, the service life of the bath itself is significantly reduced. Excessively prolonged exposure to high humidity conditions can cause premature rotting. wooden elements. This also leads to a decrease service life heaters, and certain models of stoves are not able to fully function in such baths.
Reduced service life also applies to brick kilns. This is due to the imbalance resulting from big difference between heat transfer and heat losses in the bathhouse. If the amount of heat that leaves the bathhouse is significantly greater than the heat output of the stove, then the stove will not cope with heating such a room. The result of this will be the absence comfortable conditions for a healing holiday.
Brick belongs to the category of good thermal insulation materials. But the builder and owner of the bathhouse is faced with a completely different task, which is to ensure extremely effective and rapid heating of the bathhouse, as well as to achieve the longest heat retention in the bathhouse, allowing the most comfortable and economical use of this room.

How and with what to make thermal insulation

Insulation of the walls of a brick bathhouse from the inside is done first. This should be done immediately after finishing the construction of walls and installing doors and windows.

Every qualified builder should know how to properly insulate a brick bathhouse, because the temperature in the premises depends on the quality of this work.

Attention: To ensure better heat retention, multi-layer thermal insulation is used. As a rule, they are used as the first layer slab materials, on which rolled thermal insulation material with a foil coating is laid.

The insulation technology itself does not present any difficulties. Main difficulty is to choose quality material. To make your search easier, you need to know what basic requirements a good insulation product must meet.

This:

Resistant to sudden temperature changes.
Environmental friendliness. To insulate inner part For brick baths, you should use only those insulating materials that will not emit substances that have a bad effect on health.

All these requirements are met by such material as mineral basalt wool, with which you can efficiently insulate wooden, brick and frame buildings.

Attention: The only significant drawback of cotton wool is its increased ability to absorb moisture. To insulate the floor and ceiling, you can use expanded clay or wood shavings.

External thermal insulation can be done using polystyrene foam, which has many undeniable advantages, including:

Simplicity and ease of use.
High thermal insulation properties.
Excellent slab geometry.
Excellent sound insulation ability.

Attention: However, it should be borne in mind that polystyrene foam can only be used for external insulation of brick buildings. For interior works It is recommended to choose mineral wool slabs.

Insulation of walls from the inside

The insulation of a brick bath is carried out during the installation process. Brick walls absorb moisture well, so they should not come into contact with the ground. To do this, the base is treated with a special mastic or roofing felt.

The process of thermal insulation of bathhouse walls is practically no different from the insulation of other rooms. But there are still certain features.

So:

Before you begin thermal insulation of walls, you need to insulate plastic windows. Using polyurethane foam, you need to eliminate all the gaps formed between the window and the wall.
Suspensions and metal profiles have good heat-conducting properties, so they cannot be used for insulation.
Fastening the insulation to the brickwork is carried out using two methods: using special glue or dowel umbrellas.
Also, if the wall is uneven, then you will have to do lathing. To check this, simply take the fishing line and stretch it along the diagonals of the plane. If the difference is large, then you need to install a sheathing.
The transverse lathing is made according to the width of the insulation, but the distance should not exceed one meter.
A vapor barrier material, which can be used as foil paper, is laid on the main layer of insulation.

How to perform high-quality floor insulation

The initial stage of thermal insulation of a bathhouse should be insulation of the floor. It should be understood that the floor in the bathhouse can be either solid or with well-designed ventilation.

The process of insulating a solid floor in a brick bathhouse consists of several important stages.

First of all, it is necessary to treat the base with antiseptic agents.
After this, a layer of insulation is laid on the treated surface.
Waterproofing material is laid on top of the insulation.
Finally, the floor is laid out using 40 mm tongue and groove boards.

If a brick building has a ventilated base, then the stages undergo slight changes.

First, the base is covered with a layer of sand.
Foam slabs are laid on top of the sand layer.
Then a mixture consisting of cement, sand and foam chips is laid.
The next layer will be a mixture of vermiculite, cement and sand.
Rolled roofing felt is laid on top of these layers.
At the next stage, the reinforcement mesh is laid.
All this is filled with a solution of crushed stone and concrete.
Finally, a ventilated plank floor is installed.

How to make proper ceiling insulation

Warm air rushes upward, so you need to pay attention to insulating the ceiling increased attention. For high-quality and dense insulation, it is necessary to choose reliable insulation.

For greater reliability, it is advisable to put vapor barrier foil on the side of the steam room. To eliminate the smallest holes, it is advisable to carefully glue it with aluminum tape. Foam boards are laid on top of the foil, the joints between which are treated with polyurethane foam.

There should be no baths indoors big windows and high doors.
In order for the boiler installed in the bathhouse to maintain the desired water temperature longer, it must be insulated with foil plates.
To ensure high-quality thermal insulation of a brick sauna steam room, you should choose only natural materials.
The gaps formed between the plates are sealed with polyurethane foam.
It is advisable to carry out thermal insulation of a brick bath during the construction of the building.

How to carry out external thermal insulation of walls

Now we need to insulate the brick bathhouse from the outside. For external thermal insulation work, the same non-flammable mineral wool insulation is used, which retains heat well and has good soundproofing properties.

Using roll insulation, it needs to be firmly fixed on external walls building. This can be done using wooden planks or slats.

Attention: When installing external insulation, special attention must be paid to the jointing of the insulation. After all, when deformed, it loses its properties and special attention must be paid to this.

If as thermal insulation material If mats based on mineral wool are used, you need to follow a slightly different sequence of work:

First, a sheathing made of corners and a metal profile is fixed on the outer surface of the walls;
Each cell of the sheathing is filled with heat-insulating material;
The joints formed between the mats are glued using construction tape;
The entire structure is covered with a layer of waterproofing.

At the final stage, the walls are sheathed with any finishing material.

To insulate a brick bath, you can use foam sheets. In this case, before starting work brickwork cleansed of all contaminants.

All flaws present there, such as deep seams and brick chips, are removed from the surface of the wall.
Sheets of foam plastic are glued to the plastered wall using special glue.
After the glue has completely dried, the sheets are secured with dowels. Special dowels with wide heads are screwed into five points on each sheet of foam plastic.
The joints formed between sheets of heat-insulating material must be carefully coated with glue.
Reinforcing mesh is laid and secured on top of the foam. The resulting surface is treated twice with plaster.

Now you know how to insulate a brick bathhouse. Give preference when purchasing materials to trusted brands. You should not buy cheap Chinese products. It often emits a harmful odor when heated.

It’s too early to rest and dream of a steam room with a broom, because it is necessary to insulate the structure. Brick walls have high thermal conductivity - this means that it will take a long time to heat the stove, and the temperature will drop quickly. To retain heat as much as possible, you need to figure out how to insulate a brick bathhouse from the inside.

Why is internal insulation necessary?

A bathhouse is a room that is not used daily, so during the cold season its brick walls freeze, and a lot of heat is spent on warming them up. Exterior decoration will not be able to significantly influence this situation, and placing insulation inside will make it possible to accumulate the temperature in the room and not waste additional resources.

Choice of insulation

For effective insulation from the inside, it is necessary to lay a layer of material at least 10 cm thick. The temperature in the bathhouse rises to high levels, therefore, for thermal insulation, materials are selected that do not contain toxic components that actively evaporate into the air when heated. The insulation should not support combustion, so as not to cause a fire. Another important requirement is resistance to moisture, because the bathhouse is always damp. Taking into account all the listed factors, the following are recommended as insulation for brick walls and bathhouse ceilings:

basalt wool;
Styrofoam;
expanded clay for floors and ceilings;
foil foam.

Floor insulation

The base of the bathhouse is a concrete foundation, through which the cold easily penetrates. strip foundation from the inside will significantly reduce heat loss. The best way combating freezing - thermal insulation with penoplex, produced in the form of slabs. It is not afraid of moisture and freezing temperatures, so it will last for decades. Installing the material is quite simple. The insulation is tightly glued to the concrete surface using mastic or an adhesive mixture, the joints of the panels are glued with a sealant, and the corners are blown in with foam. This layer will prevent the cold from penetrating inside the concrete foundation.

Note! Expanded clay will be an inexpensive and reliable material for insulation and waterproofing. The space under the floor is filled with a layer of granules that is 1.5–2 times the thickness of the walls. Sand is poured under the expanded clay in a layer of up to 20 cm.

Insulation of a concrete floor begins with waterproofing. Most often it is coated with liquid rubber mastic or covered with roofing felt. The top is thermally insulated with foam plastic, which allows steam to pass through and is resistant to temperature changes. The next step: securing the reinforcing mesh and pouring the monolithic screed. After it dries, the floor covering is laid.

Expanded clay – suitable option for insulating wooden floors. Beams and joists treated with antiseptic are placed on it. A vapor barrier film is laid on top, and subfloors are laid. On edged board The foam is laid tightly and covered with a waterproofing sheet. The final stage is the finishing floor.

Methods of thermal insulation of bath walls

You can preserve heat inside the bathhouse by making an additional wall from timber or laying a thick layer of insulation. For construction wooden partition You will need timber treated with a special compound that protects against moisture. Process technology:

The sheathing is fixed to the brick wall.
Using a stapler, the waterproofing film is fixed.
A wall is mounted from 10x10 cm timber, the lumber is fastened with self-tapping screws.
The second tier of the sheathing is being filled.
The roll of fiberglass is secured to the racks with brackets. The material does not stretch and is fixed with sagging.
Insulation is placed between the guides under the fiberglass. As insulation it can be mineral wool or penoplex. The last option is suitable for all rooms except the steam room.
Foil is attached to serve as a reflector of heat and moist steam.
The final cladding of the walls with clapboard is being carried out.

The second option involves replacing an additional wooden wall with a layer of insulation. The sequence of work will be as follows:

A waterproofing film is fixed to the brick wall.
A wooden beam 5x5 cm, treated with an antiseptic, is stuffed vertically. The distance between the posts is chosen to be 1 cm less than the width of the insulation, which will allow the material to be laid tightly and not create cold bridges.
Insulation with a thickness of at least 10 cm is laid.
A waterproofing sheet is attached over the material.
The second layer of sheathing is made of timber, similar to what was used previously.
Fiberglass fabric is loosely attached to the posts.
Insulation boards are tightly inserted into the gaps between the sheathing beams and covered with fiberglass.
Next, a layer of material that reflects thermal radiation is secured with a stapler. For a steam room, only basalt wool is suitable as insulation; the insulating layer is made of aluminum foil, which does not emit when heated. harmful components. In other rooms, penofol can be used for insulation and waterproofing, which reflects up to 90% of radiation and is designed for temperatures up to 100ºC. The foil material is glued at the joints with aluminum tape.
Performed . The boards are attached at a distance of 1–1.5 cm from the aluminum layer. This air gap necessary for ventilation and separation of wood and aluminum foil that heat up to high temperatures.

Internal wall cladding is made from lining of various types of wood. For steam rooms with high temperature and humidity, linden, cedar, and larch are used. They have low thermal conductivity and high resistance to moisture. The rest room is lined with pine boards, the wood has nice view, and when heated, it distributes healing substances.

Note! High humidity conditions affect metal fasteners, causing rapid corrosion. To ensure that the screws last a long time, galvanized fasteners are chosen.

The total layer of the insulating structure should be about 22 cm, then it will serve as effective thermal insulation. You can use several types of insulation in the pie; closer to the brick walls, where moisture can penetrate, it is more correct to lay polystyrene foam boards.

Ceiling insulation technology

Hot air rises to the ceiling, so it’s worth figuring out how to properly insulate it. Popular material for do-it-yourself thermal insulation work, basalt wool is resistant to high temperatures and environmental safety. Polystyrene foam is also suitable for this purpose; it is easy to cut and has low thermal conductivity. To reflect infrared heat rays, you will need foil or material with a reflective layer. In some cases, improvised means are used for insulation - clay and straw or sawdust. They are mixed in a ratio of 2 to 3, moistened and laid on the lathing in increments of 30 cm or on fiberglass. After drying, thermal insulation with a layer of foil is laid on the clay base, and sheets of plywood are stuffed on top.

Note! When working with mineral wool, it is important to perform high-quality waterproofing. The first layer will be foil, spread with an overlap of 3–4 cm and taped at the joints with metallized tape. Then the insulation is tightly laid and covered with a vapor barrier film on top.

You can replace the cotton wool with polystyrene foam, but only lay it over the steam room. mineral material. You can cover the insulating cake with boards or plywood. Interior decoration The ceiling is made of the same material as the walls.

Properly executed bath insulation with brick walls will save fuel and enjoy hot steam.

To emerge exhausted from the steam room in your own bathhouse and... freeze... It’s unlikely that anyone would be tempted by such a gloomy prospect. To prevent this nightmare from becoming a reality, you need to take care of high-quality insulation of the bathhouse. Let's talk about how to insulate a brick bathhouse.

Of course, the brick itself is quite warm material, however, the task of the bathhouse owner is to achieve quick heating of the room and a long time of heat retention, because all these are factors for the economical and comfortable operation of the bathhouse. Simply put, high-quality insulation brick sauna will make your vacation more enjoyable and cheaper.

Requirements for thermal insulation of a brick bath

The building itself has a different purpose than a residential building, and therefore the requirements for its thermal insulation are noticeably different. It is necessary to achieve not only heat, but also hydro- and vapor barrier. To do this, insulation begins from the foundation. It is laid with mineral mats.

Before the construction of the floor begins, the soil underneath is also carefully insulated: expanded clay or slag is poured. The thickness of the layer of material should be one and a half to two times greater than the thickness of the walls of the bathhouse. The floor can only be laid on dry beams and joists.

Wall insulation work

The inside of the bathhouse is finished and at the same time insulated using wood paneling. However, even before the start finishing works vapor barrier is done. As vapor barrier material Foil and kraft paper have proven themselves well.

The walls in the steam room and washing room require special care– it’s better to use foil, but for the rest room you can get by with kraft paper. The material is laid between outer wall and internal wood paneling. It is important to insulate the ceiling as well, otherwise efforts aimed at insulating the walls will give a very mediocre result.

Ceiling in special attention area

A layer of fiberglass is placed on top of the ceiling. The next layer is poured on top of the laying material. It consists of a clay-sand mortar with sawdust or chopped straw (chaff). The composition is mixed in a 1:1 ratio. The optimal thickness of the mortar layer on fiberglass is 20-30 cm. The next layer is clay-sand mortar with vermiculite (1:3, respectively). Its thickness should be about 50 mm.

In order for the insulation to be of high quality, you need to let the solution dry thoroughly. This usually takes from a couple of weeks to two months. This difference in timing is due to weather conditions. After the solution has dried, foam plastic 100-150 mm thick is placed on top, after which the entire structure is poured cement mortar with foam chips (1:3 respectively). If in the project attic room above the bathhouse, then all layers of thermal insulation are covered with roofing felt or roofing felt, on top of which a wooden floor is laid.

The ceiling will be insulated from the inside as follows: under the rough board, sheathing slats are attached with a pitch of 500 mm, between which a layer of fiberglass is fixed, after which thermal insulation (about 50 mm) is fixed. Basalt or kaolin wool is usually used as insulation. The next layer is foil fabric or foil. When all layers of insulation are installed, you can finally sheathe the ceiling with eurolining. The surface is reliably insulated.

What can you save on?

No matter how you insulate the room, if the windows are not airtight, the effect will be zero, since most of the heat escapes through window profile. It also helps to quickly cool the room large field window glazing.

Loosely inserted glass is a factor in the appearance of cracks that allow cold air to pass through, and even provoke the appearance of drafts. In general, high-quality insulation of a brick bath is possible only with a competent approach to the choice of windows, their correct installation and sealing.

All holes and cracks must be carefully caulked, and the frames must be fitted as tightly as possible to the bindings. By the way, this measure will perfectly prevent possible window fogging in the future. Glass must be carefully selected in size. They need to be well secured. Windows with single glazing are unacceptable for a bathhouse. You need at least double, or better yet triple. Perfect option– double-glazed windows.

Insulation of a brick bath is impossible without sealing the windows. They are sealed and sealed using putty. The nails that secure the glass are also covered with putty. Glass blocks can be installed. Windows serve not only to illuminate the room, but also for ventilation, so don’t forget about the window. Read more about windows for baths.

Some nuances

You can reduce heat loss by placing the windows as low as possible, installing low doors to the steam room and raising the threshold in it.
If there is no running water in the bathhouse hot water, and the water is heated in a container installed directly in the bathhouse, then it is also advisable to insulate the tank: so hot water Retains temperature longer.
It is best to fill the heater with granite and basalt. Volcanic rocks are preferable for sauna stoves.
The boiler is insulated with foil plates. This provides good thermal insulation And high degree fire safety.

When we're talking about there are no details about preserving heat in the bathhouse. By following our recommendations, you will ensure yourself easy steam and excellent relaxation. Good luck!

External or internal insulation of the bathhouse is mandatory. This reduces fuel consumption and slows down the cooling process of indoor air. If the structure is not insulated, then it will take several times longer to heat the steam room to the desired temperature.

We insulate the bathhouse with our own hands

Before constructing a building, it is necessary to calculate the means and forces for thermal insulation. It is best if the insulation process begins during construction, more precisely, from laying the foundation.

Basic requirements for materials for bath insulation

Cheap solutions (impregnations, septic tanks) will not fulfill the role of good thermal insulation. Of course, protection from moisture is necessary in any case, but this is a separate task. It is necessary to insulate the bathhouse premises separately, using materials specially created for this purpose. Most attention is usually paid to the inside of the washroom and steam room. The selection of insulation and thermal insulation is done taking into account the rough construction material.

One of the most important requirements for insulation materials - non-toxic. Because in a bathhouse under the influence of temperatures, toxic materials can easily cause poisoning. Non-hygroscopicity is also important; insulation should under no circumstances absorb moisture.

http://kakpravilnosdelat.ru/kak-uteplit-banyu/

When choosing a specific material, you need to rely on the following characteristics:

resistance to steam and high temperatures;
good fire-fighting properties;
environmental friendliness;
low hygroscopicity;
ability to maintain shape for a long period.

Types of insulation for baths

All insulation materials presented on the construction markets are divided into three conditional groups:

Of course, 50–60 years ago they used only natural materials that were brought from nearby forests. This is foam, tow or moss. Today these are already partly elite types of insulation; they cost serious money due to the need for them manual collection. Many fans natural materials They insulate their buildings with rolled jute felt or tow. This material can be purchased at construction stores. When it comes to moss, there are conflicting opinions regarding its use. They say that moss is not an ideal material for insulation because it encourages the growth of mold or fungi. However, the moss itself does not have such properties; most likely, the fungus is formed due to improper cutting wooden structure or poor ventilation.

How to work with different types of buildings

The installation procedure and the required amount of work depend on the material from which the bathhouse is built.

Insulation of log houses

When working with timber or logs, you need to take into account the drying time, which can be 10 cm or more. Plus, cracks form between the crowns of such buildings, and cold air blows into them. It is best to insulate a log house made of round timber or an assembly of timber with jute fiber.

This material does not rot and has excellent thermal conductivity. Jute itself is a very fragile material, so manufacturers try to add flax fibers to it. But if you already have crumbly material, you can perform classic caulking. This way there will be less work, and the building will probably retain more heat.

If you decide to create a bathhouse from wood, then the insulation is laid during construction. It is better to isolate all problematic parts of the log house in the process.

The work is performed in the following sequence:

Insulation of buildings made of brick or foam blocks

If log houses are insulated using a primitive method, then you will have to work hard with the masonry. Yes and financial investments more specifically for working with insulation. Additional thermal insulation is necessary, otherwise a well-heated room will cool down within hours. It’s better to work and invest in materials than to stock up on fuel the rest of the time.

A common and proven method is a suspended ventilated façade. The work process does not take place from the inside, but from the outside of the bathhouse. It is necessary to attach layers of insulation to the walls, and cover the top with siding or clapboard. In the gap between the layers, a space is formed filled with air, thanks to which condensation will not form on the walls and rotting and dampness will not follow.

The width of the frame for the ventilated facade is made larger than the thickness of the insulation, so an air gap is formed inside, preventing the formation of condensation

For a brick building, the following trick is often practiced: a steam room is made of wood inside the room. Brick absorbs heat for a very long time, so small room It’s easier to warm a steam room naturally if you use a small frame.

A 10x10 beam and sheathing are enough. The process of insulating such an improvised steam room inside a large bathhouse is simple:

You can make it even simpler: do not use timber, but instead immediately attach the insulation to the frame. In this case, an additional layer of waterproofing will be required.

Calculation and selection of materials and tools

We insulate all surfaces of the steam room, wash room and dressing room. And for this you will need:

Roll paper (for ceiling and walls).
Beam-rail (5x5, for installing insulation on the ceiling and walls).
Foil.
Insulating tape.
Self-tapping screws.
Aluminum adhesive tape.
Insulation calculated based on the area of walls, ceilings and floors.

Tools you will need:

screwdriver;
level and plumb.

Do-it-yourself insulation of a bathhouse

Any stages of insulation are always carried out according to the golden rule - start from the ceiling and end with the floors.

Ceiling insulation

Before you start working with the ceiling, you need to understand that in the steam room you need 2 times more material. After all, we are not working on a sauna, but on a Russian bathhouse, where the steam should linger as long as possible.

The technology is like this:

We cover the entire surface of the ceiling with overlapping roll paper.
We fix the bars on top of the paper, the insulation will already lie between them.
Cover it all with foil. It will become a normal, safe insulator. But it is necessary to install foil without saving. It is important that all connections are closed.
The foil layer reflects heat, so the use of such material for a bath is necessary
We seal all joints on the foil with aluminum tape. Typically, foil for insulation is included with the material.
We secure the edges and joints with several layers of adhesive tape. We check our work for leaks. If there is not enough money for such insulation, then the foil is sometimes replaced with cardboard or thick paper without paint.
