Tips for installing plastic windows in a wooden house. Correct installation of windows in a house made of timber Pitfalls that manufacturers of plastic windows do not talk about

A wooden house means comfort, warmth and a special aroma. Today, when the frantic rhythm of a big city is boring, as is the abundance of reinforced concrete, wooden buildings regaining their former popularity. In exchange for numerous advantages and logs, you have to put up with their features. For example, choosing the first plastic windows you come across and installing them using standard technology will not work - a special approach is needed, otherwise there is a risk of replacing the windows in a couple of years, no matter how high quality they are. We'll figure out which windows to choose for a wooden house and how to install them so that they last the period stated by the manufacturer.

No. 1. What kind of windows are installed in wooden houses?

Previously, in wooden houses, as, indeed, in all others, only wooden windows– there were no other options, but their quality was very different. If in the house good condition If the old wooden windows have been preserved and it would be a pity to dismantle them, then it makes sense to restore them. However, in most cases, the most logical thing to do would be to replace the old windows with new double-glazed windows, and here great difficulties await us. Question for wooden house It is also acute for those who are engaged. You will also have to pay a lot of attention to the correct installation of the window.

The following windows are suitable for a wooden house:

• ordinary wooden;
• wooden euro windows;
• plastic windows.

No. 6. Features of installing windows in a wooden house

When we're talking about About a wooden house, installation of windows is somewhat more complicated compared to concrete and other houses. The reason is strong tree shrinkage, especially in the first years after the construction of the building. Shrinkage occurs due to the wood losing stored moisture, and the worse the wood has been dried, the more volume it will lose. Over a year, shrinkage can be up to 1.5 cm per meter of height; this process is most active in the first 5 years, then the tree can also change volume, absorbing and releasing moisture. If you install a window using traditional technology, then in the first year you may not notice any problems, because the layer will compress under the weight of the wood, but then the structure itself will begin to deform, and eventually the glass will crack.

Whatever design is chosen, you will need casing, or pigtail. This required element modern wooden house, which allows you to make the window structure independent of the movement of the walls. The socket does not allow the logs to move in a vertical plane in the area where the window opening is located, but at the same time does not interfere with the shrinkage and normal breathing of the tree. In addition, the pigtail allows you to further strengthen the wall.

If installed window in wooden frame , then installation can be carried out using simplified technology. It is enough to make a vertical groove in the ends of the logs measuring 5 * 5 cm, insert the corresponding sizes into this groove wooden beam, this will be the casing.

Second option somewhat more complicated, can be used for any type of window. It consists of cutting out a ridge in a log, on which a vertical beam with a groove, called a carriage, is installed. You can make a groove in the log, and a ridge on the carriage. The tongue-and-groove design will allow the log to slide freely without moving vertically. Installation in this case is performed in the following sequence:

Installing a window in a prepared frame comes down to the following steps:

• preparing small (5-10 mm) grooves for attaching the window sill;
• installing the window sill using a level and fastening it with self-tapping screws. Plastic window sill requires the use of a rubber washer. Holes are made in those places that will eventually be covered by the window;
• leveling the window frame and fixing it with anchors, followed by foaming;
• checking the frame for verticality and horizontality, installing double-glazed windows;
• installation of glazing beads, foaming of cracks.

Of course, it is best to entrust the installation of a window in a wooden house to a professional - here you will need knowledge of the intricacies and details on which the durability of the installed structure will depend.

You can install windows in a house made of timber on your own, without calling in specialists. It is important to follow the instructions carefully. Even minor errors can lead to serious consequences and the need for re-installation. Before starting work, you should clearly determine which windows will be installed and where.

Peculiarities

The main nuance regarding the installation of windows in a house made of timber is the gradual deformation of the walls. Over time, the material changes its geometry and dimensions - a phenomenon called shrinkage. For this reason, some owners prefer to produce final installation windows and doors 12–24 months after the construction of the house. This is how many years it takes for shrinkage to occur.

There is no need to wait that long. Firstly, the phenomenon may be relevant even 5 years after construction. Secondly, windows in houses are placed in a special box, which protects them from possible deformation. To reduce the effect of shrinkage on the structure, it is worth leaving a small gap between it and the opening, the width of which does not exceed 5–7 cm. After installation, it will need to be filled by special means.

When installing PVC windows, you will need to use reflective foil tape. It will maintain quality polyurethane foam, which could be negatively affected by wood fumes. An important nuance the selection of the window sill is considered. It must be selected taking into account possible installation heating radiators. If the window sill completely covers it, the heating of the room will worsen, and the material itself will suffer significantly. The window should be several centimeters smaller than the opening prepared for it.

Important! Particular attention should be paid to the surface of the window opening. If there is mold or moisture remains, then it is strictly not recommended to install the box with a window until the wood is completely cleaned and dried.

Types of windows

For the purpose of installation in a timber building, wooden windows are most often used, although if desired, you can choose plastic ones. Both designs will last long years, and the installation is almost the same. However, they have their differences.

Wooden windows are different high level environmental friendliness They blend beautifully with the overall appearance of the house and fit into any interior. They are quite attractive in price. The disadvantages include the need for regular additional treatment with special means after 5 years of operation. This will prevent deterioration appearance material and its decay. For the manufacture of frames, pine, oak or larch (in the form of laminated veneer lumber) are usually used.

Plastic windows let in less cold winter time years, have good thermal insulation and tightness. They are presented in many models on the market, which makes it difficult to choose perfect option it will be quite simple. Plastic is easy to maintain, resistant to impacts and does not lose its properties when used in unfavorable conditions. climatic conditions. The main disadvantage is considered to be low compatibility with the appearance of a house made of timber. And a low-quality design can retain heat poorly, significantly transmit sound from the street and have a short service life.

Windows also differ in their design. The installation process for them is identical, but operation can differ radically. The issue of choice should be approached as seriously as possible.

Single leaf

The smallest of classic windows are considered single-leaf. They are ideal for a hallway or kitchen, but for other rooms the amount of light transmitted will be insufficient. Therefore, they should be inserted only in small areas.

Bivalve

Standard windows that are used in most apartments and private houses. They have two doors, one of which opens in both planes. They are distinguished by practicality and the highest levels of convenience.

Tricuspid

Ideal for large rooms. Fits best in the living room and bedroom. Windows let in a lot of light and make the interior more beautiful. Two of the three doors can be opened completely or at a certain angle.

Deaf

Fixed windows have the simplest design and are very small in size. They are designed for installation in basements or attics. The design does not imply opening, and its shape can be triangular, rectangular or round.

Required Tools

Before installing windows yourself, you should think in advance about having all the necessary tools.

You need to prepare:

• perforator;
• drill-driver;
• hammer;
• mallet;
• chisel;
• anchor plates;
• pliers;
• hexagon;
• level;
• polyurethane foam;
• spray bottle with water.

When replacing a tool with its analogue, special care should be taken, since the process of performing the same action in this case may vary significantly. You need to try not to make mistakes.

Installation steps

Installation of plastic windows in timber house It is carried out only in calm and dry weather. It should be at least -10 °C outside. Materials must be kept dry and undamaged. The same applies to wooden structures. The whole procedure takes place in several stages.

Preparing the opening

At the very beginning you need to prepare the window opening. The main task will be to maintain the evenness of the surface along all edges, which will need to be verified using a level. If the house is old, the existing windows should be removed.

Before proceeding to active actions, calculations should be made. Bottom part the window should be at a level of 80–90 cm from the floor. The dimensions of the opening must be calculated taking into account the dimensions of the window structure. They should be increased by 220 mm in width and 245 mm in height. This is necessary for installing the casing, the thickness of which on each side will be about 100 mm, gaps for insulation and gradual shrinkage.

To prepare the opening, you need to outline it with a pencil and then cut it out chain saw. After making sure that the surface is even, you need to apply a protective impregnation that will prevent the wood from deteriorating from moisture.

Casing

You can make the casing yourself. It is needed even in cases where the house is old and the likelihood of shrinkage is minimal. Its main purpose is to fix the opening and the entire structure. The casing is created from embedded or monolithic timber and installed using the tongue-and-groove system. When installing it, you need to take into account the gap at the top, the size of which should be about 15 mm for each meter of wall height.

Step by step steps:

1. Apply markings to the walls and prepared opening.
2. Make grooves 50 mm wide and deep in the side edges of the opening.
3. Place a special tourniquet inside the grooves.
4. Lay the bottom board, placing insulation underneath it.
5. Insert a 50 mm thick tenon into the groove.
6. Screw the board to the tenon with self-tapping screws (thickness 50 mm, width equal to that of the wall beam).
7. Install the top board into the grooves, placing it on the vertical elements.
8. Fill the upper gap with insulation and cover it with a special film.
9. Secure the entire box with self-tapping screws and fill the remaining cracks with sealant.

If you follow the instructions, the casing structure will be reliable. It is important that the boards used in it are dry at the time of installation.

Reference! It is possible to install plastic windows “in the deck” using carriages with grooves. However, the tongue-and-groove method is more universal and reliable.

Installation

The last step is installing the windows. It is important to make sure that the casing is level before starting work. To carry out the installation, it is best to invite an assistant, since it will be difficult for one person to cope.

Installation procedure:

1. Install the frame inside the window opening, securing it with special wedges.
2. Level the frame using a level and secure with self-tapping screws.
3. Fill all remaining gaps with foam.
4. Install ebb and flow with slopes.
5. Cash out by attaching the platbands to the boards of the frame.
6. Insert the double-glazed windows into the frame and align them with glazing beads.
7. Hang the doors on their hinges and make sure they are working properly.

The window can be used. If the curvature of the structure is later discovered, it can only be eliminated by complete reinstallation. It is recommended to ensure evenness during the installation process.

To get the maximum beautiful window and simplification of work should be taken advantage of simple tips and recommendations:

• It is not recommended to install windows immediately after building a house; even the casing does not guarantee one hundred percent protection against shrinkage;
• connections for the window structure must be sliding, which will prevent the window from deforming in the future;
• finishing should be done only after the window has been completely installed and its position has been checked for evenness;
• Before starting work, it is recommended to calculate everything down to the smallest detail and prepare the corresponding drawing.

If you have any doubts about whether it will be possible to install a window, it is better to seek the help of a specialist. If there is a lack of experience, there is a high risk of injury or structural damage, which will lead to large financial costs. To install a window in a log house, you need to perform all steps carefully and follow the instructions.

The simple installation of windows in a house made of timber allows the owners to carry out all the work without inviting a specialist. It is enough to correctly make all the measurements necessary for construction, select tools, purchase materials and windows. The nuances that exist in each such procedure are comprehended in the process of work. You need to be patient and get to work.

To install windows in a house made of timber, you will need to take measurements, prepare tools and buy the necessary materials.

Specifics of installing windows in a timber building

Any type of building is built taking into account the openings that are left for installing windows and installing doors. But if all known building materials allow a similar procedure to be carried out almost immediately after construction, then installation in wooden houses can begin 1-2 years after their construction. The condition is dictated by the fact that natural material may exhibit shrinkage. Although buildings made from laminated veneer lumber prove to be very durable, it is better to wait the required period and avoid future reconstructions.

The window is never mounted directly into the base of the wall, but only in a box, which should protect the structure as much as possible from possible deformation. Before starting work, the wood in the opening is always checked for the possible appearance of rot, defects, and accidental damage during this time. If they are noticed, it is necessary to immediately eliminate them and additionally treat them with antiseptic substances.

Since the structure can still shrink at least slightly over time, a small (up to 7 cm) gap is left between the frame and the sides of the opening. Once the process is complete, it is filled with appropriate materials and sealed to prevent drafts and to ensure the integrity of the building. For some reason, the installation of plastic windows is considered inappropriate for timber structures. The opinion is wrong, since their installation is the simplest. If white PVC windows look unsightly, you can purchase structures in wood-like colors or paint them white additional elements building.

To ensure that the quality of the polyurethane foam does not deteriorate due to wood fumes, builders use polyethylene foam foil tape, which provides the necessary shielding. After taking measurements, windows with smaller sizes of about 3-3.5 cm are selected, the width of the window sill is selected taking into account the possible placement of a radiator inside the room. The window sill cannot completely cover heating device: harm is caused to oneself PVC window, and heat transfer is also significantly reduced. If plastic side plugs are sold with the product, you must purchase them and use them during installation.

Preparing the window opening before installation

Use during installation construction foam Necessarily. It guarantees the required rigidity of the structure, its durability, and the necessary insulation.

To ensure that the foam itself does not suffer from climatic conditions, it is also additionally insulated building materials. The foam sample is selected depending on the time of year when the installation will be carried out. Since the material has the ability to expand, builders advise blowing in small sections so that voids do not form in the final version. Window installation work, unlike building construction, is carried out even in winter.

A prerequisite before starting installation in wooden houses is the absence of dust, debris, and remnants of building materials at the base of the opening. If the installation is carried out as part of reconstruction, having removed the previous structure, you need to carefully remove the upper fragile layer. Thus, the foam is guaranteed to adhere firmly and will not peel off in the future, forcing you to start the installation all over again. If in the end it turns out that the gap between the window and the frame is slightly larger, it is filled with available building materials:

• remnants of timber;
• foam;
• drywall;
• bricks.

Install small window quite simple: no need to remove double-glazed windows and sashes, installation is carried out directly. It is advisable to install large structures in the same way, without violating the integrity provided at the factory.

It is strictly forbidden to place the window flat before starting work or allow it to become distorted.

The window itself may be damaged, and pebbles and remnants of construction material will damage or even break the glass.

The protective film found on all such structures is removed immediately, since after installation, after some time it will not be easy to get rid of it: you will have to steam it with a hairdryer, which will worsen the appearance of the window and can damage the PVC surface.

The standard dimensions of indentations from the impost and corners are at least 15 cm. Moreover, if you use special ones for DIY installation mounting plates, fastening is carried out in advance using self-tapping screws, for which they are made on the frame with outside holes. Contrary to recommendations, it is better to install the PSUL protective tape at the end of the work, and not at the very beginning.

DIY frame installation

Before installing a window, it is worth considering that the technology of the work being carried out depends solely on the strength of the houses and the size of the structure. Fixation is carried out mainly by two methods:

• dowels or anchors (implemented into the walls through pre-drilled holes);
• serrated plates (attached with screws without damaging the wall).

The choice depends solely on the desire of the person carrying out the installation with his own hands, but the first method is recognized as more durable and effective. His quality characteristics guarantee that the window will not be damaged for a very long time as a result of intensive use.

The step-by-step installation of the product is as follows: wooden blocks or plastic corners, the frame is inserted so that all gap sizes are the same. When using self-tapping screws, do not screw them in too tightly until they stop. After additional checking of the correct location of the window with a plumb line and level, final fixation is carried out, for which you need to insert the window.

Having started work, leave the structure in an unfinished position for long time you can’t: it will begin to bend and become deformed, which will lead to the need to buy a new product. Screwing ends as soon as the surface of the head is level with the frame or protrudes 1-2 mm above it. Next, all existing gaps are additionally filled with foam, all foamed seams, after drying and leveling, if necessary, are covered with protective tapes, which are slightly recessed on the outside.

The gap located under the place where the water drains is filled with foam, and after its complete polymerization, the window sill that comes with the product is installed. It is inserted to a depth of 2 cm and fixed. The window sill cannot be located perfectly level (only at a slight slope), which will ensure moisture drainage. To do this, it is foamed from below in the space remaining between the house and the window sill.

The window opening must be completely ready no later than 3 days from the start of work. Thus, it will be possible to avoid possible deformation of the material and the structure itself. But you cannot use the product right away. The window should not be touched for about a day to avoid possible damage to the installation. Own house- This is a great responsibility. If the owner is not going to conduct self-installation windows, you can hire a team of installers.

The performance qualities of plastic window structures allow them to be used in the construction or repair of any buildings and structures. When working, it is worth taking into account the differences and features of the installation process.

Let's study in more detail the intricacies of installing windows in a wooden house.

Peculiarities

The peculiarities of installing plastic windows in a wooden house require a number of additional manipulations. This is due to the fact that the structure settles over time. Moreover, such work has differences in an old wooden house and in a new, newly built dwelling.

Before moving on to studying it, it’s worth clarifying what you need to know about shrinkage. This is a natural process of changing the parameters of the walls due to the drying of the wood base.

Shrinkage wooden structure depends on a number of factors:

• type of material (timber, laminated veneer lumber, log);
• time of material procurement (summer, winter);
• time of day of collection (evening, morning, afternoon);
• area of ​​forest growth (field, swamps);

• density and resinity of the material;
• dimensions;
• humidity indicators;
• dimensions of the entire structure.

The greatest shrinkage will occur in a log frame. The shrinkage parameter of a rounded log has a lower value. The shrinkage rate of new laminated veneer lumber is even slightly lower. There will be practically no shrinkage observed in an old timber or log house.

Almost any wooden house is a constantly moving structure. This phenomenon is practically not observed in stone or concrete structures. Due to instability wooden structure The installation of PVC windows should not be carried out in a previously made opening, but in a pre-prepared box. It will represent a connecting link between the wall and the window structure.

The box is called differently: casing, pigtail, linden, etc. Without this element, a wooden house will “walk” and begin to put pressure on window structures.

In the shrinkage gap between the top in the casing and the wall of the house It is not recommended to use polyurethane foam. The hardened mass is rigid, so it will transfer the pressure of the upper elements of the wall to the window, negating the functions of the casing. The upper casing gap is insulated with other materials, which you will learn about later.

Another pitfall when installing windows can be incorrect calculation of window sizes. Without taking into account the installation gap, the window opening will have to be expanded in any case.

Negative on performance qualities the design will be affected by too large a window opening. Simply foaming it cannot be reduced, and without proper insulation, the slopes will always be cold. When installing windows, it is important to immediately protect the installation gap. The cracks on the outside are closed with special tapes.

Another one important feature installation of plastic windows - exact compliance with the level. Inaccuracies at this point will lead to rapid failure of the fittings.

It is also important to take into account the correct placement of the window in the wall. For example, if it is located in a cold zone, this will cause it to freeze. Condensation will certainly accumulate on the inside.

Knowing the features of installing plastic windows, you can decide to install them yourself. After all, many companies providing such services do not guarantee their work, citing the unpredictability of wood behavior. Therefore, it is worth exploring casing options in more detail.

In addition to plastic windows, in a wooden house you can install metal-plastic structures, wooden, aluminum, combined. Wooden windows have a lot of advantages, but among others they are the most expensive. Plastic structures more affordable, low maintenance. Modern manufacturers offer designs in a wide range of colors.

When choosing any design, it is important to understand the installation process of a window structure. This is needed not only for self-installation. Knowledge is also important for monitoring the process of work that employees will perform.

Casing options

Casing is definitely needed for windows that will be installed in a new wooden house made of timber or logs. The structure will also be needed for unstable soils. It will be additional protection for the window, which in this case may become warped.

There is no need to do casing for windows frame house. Here the frame itself will provide the necessary rigidity of the structure. Considering the simplicity of the casing construction process, it is still better to do it for this type of building.

The correct casing installation technology involves the use of three types of structures:

• spike-monolith;
• embedded block;
• into the deck.

The most labor-intensive part is the tenon-monolith casing., but she is the most reliable. For this design, a groove is cut out in the box, the dimensions of which fit the pre-prepared tenon on the sides of the box. If you do not have carpentry skills, it is best to install the casing in the embedded block.

Casing “in the deck” is the most expensive both in terms of labor costs and materials costs. The guide for the box here is a spike, which is installed in the end parts of the opening. Grooves are cut on the sides of the tenon. The top is attached to the side decks with self-tapping screws, and the window sill is installed on wooden dowels.

Installation of any window frame begins with the window sill. After this, work moves on to the apex, under which side stands are needed.

It must be taken into account that the maximum shrinkage of the house is about 35 cm depending on the strength of the base. Can give greater shrinkage ordinary timber- up to 40 cm, and less - laminated veneer lumber. The consequences of incorrect calculations may manifest themselves later in operation, resulting in the need to replace the entire structure.

Material for casing can serve as glued or monolithic timber. The use of laminated veneer lumber is not recommended in bathhouses, but this material is suitable for home use. Temperature and humidity changes are observed in the baths, causing the laminated veneer lumber to collapse.

If monolithic timber is used, it is important that it is dry. Material with moisture content greater than 12% will behave or crack.

Monolithic timber must be specially chamber-drying; if this is not available, the material will have to be dried in the shade for about 4-6 months.

There are also such types of casing as:

• Draft. The cheapest materials are suitable for it. Casing is used for planned internal and external finishing works. In contrast, finishing casing does not require finishing. It already has a slope; the window can be installed immediately after attaching the frame.
• Arched. This decorative variety prized for its originality. This design can use several glued parts or a single curved block.

• Power. This option is used for large-scale panoramic windows, gates, balconies, as well as doorways. Thick wood is used for manufacturing.
• Eurosurface. This option is similar to finishing, as it does not require additional finishing. A special feature of this type is the use of solid lamellas with a special adhesive composition.
• Combined. This option is made from solid wood, and has an outer layer of a type-setting adhesive decorative base. This type combines the beauty of appearance and low price.

The casing for plastic windows of a wooden house can also be plastic. The installation features of this type require a wider opening in the log house (at least 10 cm) from the width of the glass unit. The manufacturing scheme involves installing a carriage with grooves, the dimensions of which should allow the frame to slide easily along the guides.

Preparatory work

General rules preparatory work will be as follows:

• A compensation gap is required between the top of the casing and the horizontal part of the window opening. It accounts for the maximum shrinkage of the house, which is possible at the time of installation of the frame.
• Wooden casing elements (tenon, groove, ends, top) must be treated with an antiseptic.
• The insulation is placed between the casing and the end of the wall. Suitable materials include flax wool and jute. The materials are secured using a stapler. The upper gap is insulated inside and outside. The insulation is secured with steam and waterproofing tape. If the tape is not sticky, it can be fixed with a stapler.
• The lower part of the frame is insulated with two-layer flax or jute. A windproof film is needed between the frame and the window sill.

• The frame is attached to the frame from the outside long screw, which should press the structure along the entire plane of the box.
• If there are gaps on the outside, they are carefully insulated.
• At this stage, it is undesirable to use polyurethane foam. It will prevent shrinkage. Foam should only be used as a last resort together with a vapor barrier.
• The best protection option would be to carefully caulk the gaps and then seal them with waterproofing tape. The main goal There must be no way for moisture to get on the insulation.
• Lastly, the trims are attached and the ebbs are installed.

To determine the size of the gap, you need to take into account the thickness of the box material, taking into account the seams and the shrinkage coefficient of the structure.

Important preparatory stage– marking the opening for the window. Before you start cutting out the opening, you need to accurately mark it, and for this you need a level. The window opening must correspond to the levels on all planes. The pigtail must be cut as accurately as possible relative to the given level.

If the house is not made of timber, but wooden, lower crown The opening for the window must be cut out in such a way that a horizontal surface is obtained. The size of the opening is determined by the parameters of the window design, taking into account the size of the gaps.

Preparatory work involves the installation of a pigtail, which can be:

• T-shape. For it, a hole for a groove is created inside the end of the log slope. In the future, you need to place the profile in this groove.
• U-shaped. To do this, you need to cut a spike at the end of the log wall. In this case, a groove is created in the side casing post.

Installation

You can insert the pigtail correctly with your own hands from the windowsill. Step-by-step instructions further implies the installation of slopes, and on them - an apex. Insulate wooden parts casing is better after external platbands without window glass are installed.

Put window frame You can initially use self-tapping screws to connect the pigtail. Fasteners must completely penetrate the body of the structure, but must not penetrate the wall. It is unacceptable for self-tapping screws to be screwed into the log. Therefore, the length of the fastening elements should not be greater than the width of the frame. Special wooden brackets can be inserted as fastening elements.

Okosyachka

As a result of correctly carried out preparatory work, the frame along the frame should stand perfectly straight. The leading edge is placed strictly parallel to the casing plane. There should not be any significant distortions.

Decide what kind of waterproofing you will use when processing the gaps between the window frame and the glass unit. If the gaps are filled with foam, then it is worth considering that it is afraid of light and moisture. The seam is covered with platbands. The waterproofing used should not let water in, and moisture vapor should not escape outside. Proper waterproofing should not be susceptible to weathering.

If the frame is installed clean, this allows you to save on lining the window sill and slopes. For a more attractive final result, you need to know how to properly process wood. Accurate sizing calculations are also important, especially if done independently. Despite some difficulties, the solution with a finishing socket is the more correct choice.

Double-glazed window

Place the glass unit in the opening and carefully monitor the installation accuracy relative to the front edge of the frame. In wooden houses, it is not necessary to install a double-glazed window inside a third of the wall thickness. This is required by panel or brick buildings, as well as frames. The thermal conductivity of wood is lower compared to these structures.

If in a wooden house a double-glazed window is placed deep into the opening, the result will be a reduction in the already narrow window sill. In this case, the ledge from the outside must be additionally closed and subjected to hermetically sealed treatment. When installing plastic profile It is worth considering that the main conductor of cold inside is the profile itself.

A waterproofing tape with a vapor-permeable effect is suitable as a profile processing material. In combination with the tape, you can use Stiz-A sealant. It is acrylic, one-component, white, and adheres well to basic building materials, including wood.

The procedure for filling the gaps between the casing and the window structure is as follows:

• foaming;
• waiting for the foam to dry;
• cutting off excess foam with a spatula;
• sealing seams with tape.

You can buy self-adhesive tape in stores, which includes a membrane and a sealant applied on one or both sides. Rolls on sale come in various widths. For plastic windows, a narrow tape is sufficient. It looks like foam rubber. The foam on the inside of the window should also be closed. Special tapes are also selected for vapor barrier.

• Do not use metal fasteners when connecting casing parts.
• Observe optimal distance standards. For example, there should be at least 90 cm from the window sill to the floor.
• Install windows in a wooden house closer to the outside of the wall.
• Choose hard wood as a window sill. Usually, best qualities will have a window sill made of solid wood.
• Align the corners of the window opening with a level, setting it to 90 degrees. Diagonals may differ by 10 mm.
• Correctly calculate the window seating depth. The dew point contour should run along the inside of the opening. This way you can achieve the absence of condensation on inside designs.

When processing casing both inside and outside, you can use various options color and texture design of surfaces. Once the window installation is complete, everything wooden surfaces You can simply sand and varnish. Use a stain that matches the color. This way you will achieve a more harmonious appearance of the window sill and other parts of the casing against the background of the walls or window.

Usage natural wood during construction is gaining momentum due to safety in relation to the environment and human health.

The appearance of a house made of timber differs from banal brick “boxes”. To make it aesthetically pleasing, it is important to select and install windows correctly.

Features of installing plastic windows in a timber house

Having completed the main construction, the owner of a wooden house asks himself: to install plastic windows himself, while saving money, or to entrust the installation to professionals. The answer is clear: it is better to order the installation from specialists, since it requires a certain technology. Companies specializing in such services know how to insert a double-glazed window into a timber structure to avoid negative consequences in case of errors in installation, and the work will take a minimum period of time.
A plastic window cannot simply be inserted into the opening; it is first created special design. It is several centimeters larger than the glass unit itself in case the wood dries out and will not allow it to be squeezed out or compressed. The casing, or frame, strengthens the wall and takes the load upon itself. Using this technology, there is no need to wait for the shrinkage process, but you can install double-glazed windows immediately after the completion of the construction of a wooden house.
Stages of casing manufacturing:

• Sawed into window opening special combs.
• A window carriage with a groove is put on.
