Every reader of the site knows that no matter what material the windows are made of, they help keep the house warm and emphasize the individuality of any home. Therefore, the installation process should be treated with special attention. After all, even the most expensive and energy-efficient window design loses all its advantages if it is installed incorrectly. In this article, our experts tell you how to properly install windows in wooden house, frame and stone.

Wooden, stone and frame houses And country houses have a number design features. Since they affect window installation technology, any developer should be aware of them.

From our article you will learn:

  • Where does the preparation for installing a window structure begin?
  • What stages of work precede the installation process;
  • What features should you be aware of in order to install windows in wooden, frame and stone houses;
  • How to install a wooden window with your own hands - how different is its installation from installation? plastic window;
  • How are installation joints protected?
  • How to control the installation process.

Preliminary preparation

Despite its apparent simplicity, installing windows at home is a process that requires a serious and responsible approach. After all, the quality of installation directly affects the level of comfort in the home. Here's where the process begins:

Anton Karyavkin Head of the technical center of REHAU, Moscow.

First of all, you need to carefully prepare: read the instructions and existing installation standards, and acquire the appropriate tools.

A professional installer's kit includes about a hundred different “tools”. You don't have to have them all, but without basic set It will not be possible to install a translucent structure. It includes: a hammer drill, a screwdriver, a foam gun, a chisel, a hammer and screwdrivers.

When choosing tools, you should also take into account that window installation involves a wide range of additional work.

These include:

  • Plastering slopes in stone buildings;
  • Construction of seams and thermal insulation;
  • Installation of window sill and additional components.

The main thing to remember is that the installation technology directly depends on the material of the building walls.

Anatoly Gavrysh Head of the design bureau of the Window Factory company

The type of house significantly influences the window installation procedure. In houses where there is significant shrinkage (most often in wooden houses), a casing floating box with compensation gaps is used. In other types of houses, window installation has the same patterns.

Installing wooden windows in a frame house with your own hands.

Install wooden windows with your own hands

Developers believe that between PVC installation There is a big difference between a wooden window and a wooden window, but experts disagree.

Anatoly Gavrysh:

There is practically no difference between installing a plastic and wooden window. The slight difference lies only in different fastening elements.

Do-it-yourself installation of a wooden window should be done more carefully. And in each case an individual approach is required.

Alexander KorpachevHead of the installation department of the company "Business-M"

Even windows in the same house can have their own characteristics. Therefore, in your work it is necessary to adhere to the recommendations of GOSTs, namely:

  • Window installation seams - with vapor-permeable self-expanding tapes;
  • Technical specifications, GOST R 52749-2007;
  • Assembly seams of units and junctions of window blocks to wall openings;
  • Are common technical specifications, GOST 30971-2002;
  • Window blocks are made of polyvinyl chloride (PVC) profiles. GOST 30674-99.

In general terms, the installation consists of the following steps:

  • Preparation of the opening;
  • Window preparation;
  • Installation;
  • Finishing work;
  • Finishing.

Anatoly Gavrysh

I would like to dispel illusions about the ease of installation of both plastic and . To carry it out yourself, you definitely need certain skills and special equipment, since correct installation is of decisive importance in how high quality and how long new window structures will last.

In detail, the installation of both plastic and wooden windows is done as follows:

1. Window openings are cleaned of dust and dirt.

2. The windows are installed in the opening and wedged with small plastic or wooden corners strictly according to the level.

Corners are necessary to form a gap (margin) between the frame and the opening. Along the perimeter - between the window and the opening, it is recommended to lay a technological gap for foaming 20 mm wide. At the bottom of the window - under the window sill, it is recommended to leave a margin of 35 mm.

3. The structure is fixed.

Fixation is carried out using dowels or special mounting toothed plates. If the window is fastened through with self-tapping screws, then before doing this, holes for the anchors are marked and drilled in the opening. The number of attachment points depends on the size of the window and on average ranges from 40 to 70 cm. From the corners of the frame it is necessary to make a distance of 12 -15 cm.

4. The seams between the window structure and the opening are foamed.

To save foam, if the gap exceeds 40 mm, it can be filled with insulation - polystyrene foam, etc.

5. The foam is covered with steam and waterproofing tapes.

The vapor barrier is glued along the entire perimeter of the window structure on the inside (from the room side), and the waterproofing film is glued on the outside, from the street side. After foaming, the protective strip is removed from the tape and the foamed seam is closed.

6. Additional elements - flashings and platbands - are installed in their place on the outside (if the installation takes place in wooden houses).

7. The fittings are adjusted.

Features of installing windows in a wooden, frame and stone house

Anton Karyavkin

Installing windows in buildings made of rounded timber is the most difficult. This is due to a design change wooden houses from manufacturer to manufacturer.

If developers use different types of wood when installing windows in a wooden house, it is almost impossible to predict the behavior of the material - each time you have to study everything from scratch. The deformation of logs in such buildings can be quite large: from 8 to 15 cm. The house shrinks, so not a single window in such conditions can remain operational for a long time.

Correct windows in a wooden house.

Here's what we can do to protect the structure from possible deformations caused by shrinkage of the walls, using the old carpentry method:

Anton Karyavkin

The most responsible developers begin cutting an opening in timber walls only a year or even two after the construction of the house. During this time, it is possible to track all deformations, taking into account the characteristics of the material and the climatic characteristics of the region.

After the opening is cut, a rough frame, also known as a “frame” or “casing”, is inserted into it, into which the window structure can then be laid.

Alexander Korpachev

In all wooden houses, when installing windows, it is necessary to use a casing or frame - a wooden box that levels the load on the frame.

Between the upper part of the window opening and the frame, a technological margin of 30 to 70 mm is usually left. After installation, the stock is filled with insulation and covered with platbands on both sides.

Anton Karyavkin

The box is made from wooden blocks 50-80 mm thick.

Despite the fact that the box absorbs the deformations of the logs quite effectively, the installation joints in this type of building still remain movable. Here it is important to choose the right mounting foam - it should not collapse when the walls shrink. Such correct foam can be found on the market, but it is relatively expensive. Therefore, experts often replace it with other materials, mainly of plant origin (tow). Of course, the tape and coating materials necessary to protect the installation seams must also have a high class of deformation resistance.

Glued laminated timber shrinks significantly less than solid logs. Eventually laminated veneer lumber deforms less than a regular log.

But it is still difficult to install windows in a wooden house with your own hands.

How to install a window in a frame house

Wooden windows can also be installed in a frame house, but plastic windows are most often used. Control of the installation of any windows at all stages should be checked using a level or plumb line, and the horizontal and vertical deviation should not exceed 1.5 mm per meter.

Anton Karyavkin

The process of installing windows in a frame house is much simpler than in a wooden one. You will still have to deal with deformations of the window opening, but they are no longer so significant.

It is better to use anchor plates as fasteners. Installation with construction screws is not recommended: they secure the frame, and deformation of the wood, in turn, can cause damage to the windows.

How to install a window in a frame house

It is important to remember that when installing a plastic window in a framed room, it is necessary to wrap it into the window opening. This is necessary in order to connect the window vapor barrier circuit with the room vapor barrier circuit.

Brick different types, concrete, aerated concrete blocks- these are standard Construction Materials. The technique in stone houses has been worked out for years. Fastening is carried out using dowels and construction screws; the use of anchor plates is also allowed.

Anton Karyavkin

In some cases, installation technology may be influenced by design decisions that require taking into account the linear dimensions of structures and wind load in the region.

Protection of installation joints and control stages installation work

Regardless of the wall material, it is necessary to protect the polyurethane foam from ultraviolet radiation and atmospheric moisture. Otherwise, it will become loose and lose its properties over time. To protect it, special insulating tapes and sealants are used. The latter are good because they allow you to cover any cracks and irregularities, unlike mounting tape, which requires a perfectly flat, dust-free surface.

Installing windows yourself will save up to 50% of the money that would be spent on installation by a third-party company. But it is very important to do everything correctly, otherwise the savings will be questionable. Wooden houses have their own characteristics that you should be aware of.

Possible problems if windows are installed incorrectly

It is advisable to adequately assess your strengths in advance, because some mistakes can become very expensive:

    • lack of casing - a house made of timber “walks” during shrinkage and begins to put pressure on the window frames;
    • using polyurethane foam in the shrinkage gap between the top of the casing and the wall of the house - the hardened foam is very hard and will transfer pressure from the upper beams to the window frame, negating the functions of the casing;

    • incorrect calculation of the dimensions of the plastic window frame - without taking into account the installation gap, you will have to expand the window opening;

    • there is too much gap between the frame and the wall - if you simply foam such a gap, the slopes will always be cold, it is better to insert an additional expansion profile;
    • lack of external protection of the installation gap - when foaming the distance between the frame and the casing, it is better to close the gap from the outside with PSUL tape, which provides protection for the foam from ultraviolet radiation, but allows moisture to evaporate;

    • lack of waterproofing from the outside and vapor barrier from the inside - the foam is destroyed when exposed to the atmosphere, which leads to a deterioration in insulating properties;

    • placing a window in a “cold zone” causes freezing of slopes and the formation of condensation on the inside

If there is the slightest possibility of making one of these mistakes due to inexperience, it is better not to save money and order window installation. For an experienced builder, DIY installation should not be a problem.

Pitfalls that plastic window manufacturers don't talk about

The tightness and high sound insulation of plastic double-glazed windows is presented as a definite advantage. But, unfortunately, not everything is so rosy. After all, the humidity in living spaces is constantly increasing, and thanks to unsealed wooden frames, a constant flow of fresh air is ensured. Of course, too large gaps can make the house very cold, so Euro-windows have long become a very popular product.

How to solve the problem with high humidity? One option is to do forced ventilation. But in the absence ventilation holes This can be problematic - you will have to redo a lot.

It is for such cases that window frames were invented. supply valves– special profiles that are installed on plastic windows. What is especially pleasing is the ease of installation. It is enough to replace part of the standard seal with a special one and screw the valve to the window sash with several self-tapping screws. Unfortunately, the system will not work without an exhaust vent.
Another unpleasant surprise for owners of wooden houses is that companies that install plastic windows often do not provide a guarantee for their work, citing the unpredictability of wood behavior. So, even if all installation rules are followed, you may find that after a few years the windows no longer open. But you won’t be able to sharpen plastic with a file.

Manufacturing of casing (plugs)

The first thing the installation of windows begins with is the installation of the casing. But is it always necessary and how to do it correctly?

When can you do without a joint?

A new wooden house made of logs or beams will shrink in any case. And no one has canceled seasonal soil heaving. In this case, the casing is required - it will protect the window from distortions, torsion or bends.

It is important to use only dry and durable material– edged board 50 mm thick and edged beam 150x100 mm or 50x50 mm. The width should be equal to the thickness of the wall.

But in frame house There is no need to make a frame - the frame itself is already formed for window and door openings and provides the necessary rigidity. Some builders also do not install a casing in a log house that has stood for more than 10 years, arguing that it has already undergone shrinkage and is not deformed. But for peace of mind, it’s better to do it in your home; this process is not that complicated.

How to make casing correctly

The last option is the most labor-intensive, but also the most reliable. If you have any doubts about your own carpentry skills, it is better to casing it into an embedded block. For this:

    • IN window opening, in the middle of the timber, two vertical furrows measuring 5x5 cm are selected. This can be done either with a chainsaw or with a hand circular saw, chisel and axe. The second option is preferable if your hand is not equipped for precise chainsaw work.

    • An edged board is laid on top of the embedding block and secured flush with self-tapping screws - two at the top and bottom. To do this, pre-drill a small recess with a diameter slightly larger than the screw head.
    • If the “tenon-monolith” casing option is chosen, then the pre-cut T-shaped element is simply driven into the groove and also screwed with self-tapping screws.
    • Vertical elements should not reach the upper edge of the opening by 8 cm - so that the 5 cm thick top laid on them is at a distance of at least 3 cm from the wall beam. This will be the shrinkage gap.
    • The top should fit into the grooves with little effort, and not move freely in a horizontal plane. It is also fixed with self-tapping screws, screwed in at an angle.
    • The insulation is placed in the shrinkage gap and closed on the inside with a vapor barrier, and on the outside with a windproof membrane. Under no circumstances should the insulation be covered on both sides with vapor-proof films - accumulated condensation will cause mold to form on the wood adjacent to the insulation.

And this is how casing is done “into the deck”:

When the frame is ready, you can proceed directly to installing double-glazed windows.

Do-it-yourself installation of plastic windows

The installation of double-glazed windows itself is not very complicated, but requires strict adherence to technology. Otherwise, the window will almost certainly condense and the frame will warp.

Checking the delivered glass unit

Under no circumstances should this moment be neglected! First, the dimensions of the window opening and glass unit are checked. So, if the opening is 184 cm, then the window frame should be 180 cm - the gap between the side posts and the wall cannot exceed 2 cm on each side. The height of the window opening, for example, is 120 cm, then the frame itself should be 116 cm, and at the bottom there is also a support profile (clover) of 3 cm. Thus, the gap at the top will be 1 cm. The clover must be included in the kit, and under You need to leave room for it when designing the window. It is needed so that a window sill can be installed from the inside, and the ebb can be screwed on the outside.

If mosquito nets are planned on the windows, you must also check the presence of fasteners. Handles are often “lost” because windows are shipped without them. But dowels are special fasteners that you need to select yourself.

Their length should be such that when fully screwed in, they only reach the middle of the casing board. And this is taking into account the gap. If you screw the dowel into the wall wooden house, the window will begin to deform regardless of the presence of the frame.

Often they do not pay attention to small elements - decorative trims, fittings and drainage holes. They will also have to be counted. But the window sill and sill need to be ordered - if you forget to specify their necessity, you may find that the windows arrived without them. For installation, you will also need special linings for the glass themselves - their presence can only be seen by disassembling the double-glazed window.

They may not be included in the kit, so it is better to order them in advance. Wedges are convenient because, thanks to their different sizes, you can align the frame evenly by simply placing a wedge of the required thickness under the corners and posts.

Disassembly and preparation of double-glazed windows

The finished glass unit is delivered in assembled form. But to install it, you will have to disassemble everything down to the frame. For this:

    • when closed, use a special key to remove the upper pins holding the swinging sash;
    • the window handle is inserted, the sash is opened and removed from the lower fastenings;
    • the glazing beads are knocked out from the inside of the window and the double-glazed windows are removed - you can use a hammer and an ordinary knife;
    • you need to remember or mark the right and left glazing beads;
    • removable from the outside protective film– under the influence of the sun it will not come off in a few months;
    • external elements are installed - mosquito net holders and decorative plugs for drainage holes;
    • holes are drilled for the dowels - first at a distance of no more than 20 cm from the corners of the frame, and then no more than 60-70 cm from each other;

Once the preliminary preparation is completed, you can proceed directly to installation.

Installation of frame and assembly of plastic windows

First, the frame is simply inserted into the window opening and temporarily fixed in it. For example, with temporary jibs nailed on the outside. But it’s much easier to do everything with an assistant - he simply holds the frame until it is leveled and screwed to the casing. Installing the frame also requires following the correct sequence:

    1. The lower edge is aligned with the level - a laser level is more convenient in this regard. Wedges of different thicknesses are placed under each rack to achieve a perfectly level position. Even minimal distortion will create problems during operation.
    2. Side spacers are inserted to ensure the same distance from the walls. If width window frame is too small and literally “falls out” of the opening, you can use a special expansion profile. This is much better than foaming the resulting huge gap.

    1. The frame is also aligned vertically. Don’t forget that it needs to be installed in a “warm” zone - for wooden walls without external insulation, this is clearly in the middle.
    2. Once the frame is level, you can begin attaching it, starting with the side posts. First, holes are drilled in the wood through those already made in the frame, and then dowels are attached. First the top and bottom, with a mandatory check of the vertical, and then between them.
    3. Once the frame is fixed, the flashing is attached to the outside. Of course, this can be done as a last resort, but on the second floor it is not so easy to approach from the outside. The ebb is inserted into a special groove under the frame, screwed with two self-tapping screws along the edges, and the gap under it is filled with polyurethane foam.

    1. Decorative overlays are placed on the sash fastening elements. The lower ones are put on the frame, the upper ones - on the sash. First, the sash is installed on the frame, and only then the handle is attached in the open state.

    1. Double-glazed windows are placed on special gaskets. Without them, the window may simply burst due to the emphasis on the metal parts in the corners of the frame.

    1. Foams installation seam along the perimeter.
    2. A window sill is being installed. To do this, a finished window sill is placed on the window sill beam, and wedges are placed under it to level it. The window sill is removed, its end and delivery profile are coated with sealant, and the free space between the wedges is foamed. The window sill is placed again, pressed tightly against the profile and left until the foam hardens.

  1. In some cases, they do the opposite - first they install the window sill, check it for level and screw it to the casing with dowels. And only then a double-glazed window is placed on top of it. In this case, there is no need to align the frame horizontally. The only inconvenience is that the window sill material must withstand the action of the external environment. Of course, you can fix the ebb outside on top of the window sill and foam everything under it, thus protecting the wooden element.

Once the polyurethane foam has hardened, you can begin finishing the windows.

Slopes for a plastic window in a wooden house

The easiest option that even girls can handle is to close them plastic panels. For this you will need:

  • L-shaped or starting profile - it is screwed to the wall close to the window frame;
  • decorative plastic corner– it covers the end of the panel from the side of the room and is also screwed on with self-tapping screws;
  • the plastic lining itself for the slopes.

And you don’t even need to foam anything. But in order to provide the necessary protection for the assembly seam and good insulation, you should lay insulation between the wall and the slope and cover it with a vapor barrier. The seam is closed on the outside windproof film– waterproofing with good vapor permeability.

And in order for the windows to delight you with warmth and comfort, it is very important to protect the polyurethane foam from exposure to ultraviolet radiation, as well as from being pulled away by birds. There is no need to restrain the impulses of your soul if you want to start doing something with your own hands. And everything will definitely work out!

Glad to be useful to you again, my friends!

After examining my windows in a wooden house, I came to the conclusion that it was time to replace them. I had never encountered such a process before, so I made up for the lack of practical experience with the help of other people’s knowledge: I searched through a bunch of forums and websites, and through friends I found people who had already done similar work. Then I made a number of conclusions and determined the algorithm for my actions when reinstalling windows. Next, I will present everything sequentially.

First of all, I measured the windows and ordered new ones, providing the exact dimensions. While the order was being fulfilled, I began dismantling the old frames and then clearing the openings of accumulated debris. Upon receipt of the windows, I installed window sills and prepared double-glazed windows for installation. I placed the structures in permanent places and secured them. Of course, in reality the process was not so quick and easy, but there is nothing overwhelming about it - I managed it and you can too.

Technology for installing a plastic window in the opening of a wooden house

When installing a plastic double-glazed window into the frame of a wooden house, you cannot do without a level and plumb line - if you want the window sashes to move smoothly, not open under their own weight, or jam. Then never fix a window without making sure – not by eye, but by level – that it is level.

To ensure that the work involved in inserting the window into the opening and leveling does not go down the drain, it is necessary to fix the leveled structure with mounting fasteners.

Most best option– 6 pieces for each window. They can be ordered in the same place where you submit your application for the production of double-glazed windows.

There are technical slides for these fastenings on each side of the window, so there will be no difficulties with the correct placement of the plates. Each plate has holes for self-tapping screws. Is it possible to do without plates? Yes, if you want to drill through it when attaching the frame, which will cause depressurization of the chambers in the profile. Personally, I am against such barbarism - I need windows not only for beauty, but also for reliable protection from cold and moisture. And tell the installers, if you don’t install them yourself, to install the windows according to the rules. Only in this case will the expectations from plastic double-glazed windows in a wooden house be fully justified.

I highly recommend removing the window sashes from the frame before installing it in the opening. This won’t take much time, but it will save a lot of effort: without it, it will become much lighter and directing it to the right place will be easier.

Algorithm for installing a double-glazed window into the opening of a wooden house:

  • Having inserted the structure into the frame, insert wood chips 2 centimeters thick under the lower frame;
  • using a water level, determine the quality of the installation;
  • achieve the desired indicator by placing additional chips;
  • Use the same pieces of wood to level the frame vertically;
  • Having determined the most optimal position, secure the frame to the post with self-tapping screws, inserting them into the holes on the mounting plates.

When screwing in each self-tapping screw, do not hit the ridge of the log into which the pigtail rests. To avoid loosening the screw, screw it in slightly at an angle.

After fixing the frame, foam it along the contour only after hanging the sashes - they will prevent it from bending under the pressure of the hardening foam. If the sashes are not installed before this, then later there will be problems with the movement of the vents even in a perfectly installed frame.

After leveling the frame horizontally and vertically, a 2 cm thick gap should remain on each side of the entire structure for filling with foam. The height of the distance between the top panel of the frame and the first log is no less than 5 and no more than 15 cm - the gap will prevent the wood from pressing on the windows after the frame shrinks.

Before pouring the foam, a control check is required to ensure the correct installation of the entire structure. They focus on the “behavior” of the open sash: it should not independently go further than it was opened, or try to return back, obeying its weight, and not you.

Here is a short educational program on the topic of installing plastic double-glazed windows in a wooden house. I hope that my advice will help you in your noble and exciting endeavor.

Self-installation

I wanted to install plastic windows in my country wooden house. Everything that will be described below is a verbal statement of my experience with self-installation double-glazed windows in a timber house.

Why did I decide to install the windows myself?

There are several reasons:

  • for installation you will have to pay up to 50% of the cost of the window itself (with the savings from 2 installed yourself, you can buy a third);
  • almost all companies that provide window installation services in wooden houses do not provide any guarantees for their work;
  • there is no need to pay for a service that any owner can provide to himself in 2 hours of work.

In order for the installation result to please you for many years, you need to adhere to the recommendations below step-by-step algorithm actions.

Removing old windows

Regardless of who will install new double-glazed windows in a wooden building - you or invited workers - It is permissible to install new structures only on a rigid foundation. I was lucky: the window casings in our house were replaced a couple of years ago, so the wood was flawless. That is, I did not find any wormholes, rot, cracks, dents or chips on it. Therefore, when ordering double-glazed windows, I indicated the dimensions of the new windows, taking into account that the boxes would remain. If in your case the condition of the frames turns out to be not very good, but your housekeeping will not allow you to throw them away, then the dismantled items can be used as the basis for a mini-greenhouse.

Don't know how good and bad the boxes under your windows are? All the same, do not allow either yourself or your employees to break them out “with meat”. You will always have time to use it for firewood. The same applies to glass: there is no certainty that they will not crack during dismantling, so take it out first - they will also find a use. I was lucky again: the frames were still strong, so the structures were removed without removing the glass.

How to prepare a place

Walk around the entire perimeter of the frame with a dry brush or clean rag to sweep away anything remaining after dismantling.

Window sill installation

First to be assigned to a permanent place plastic window sill , which is “charged” with serving as the basis for the rest of the structure. Hence the “legs grow” of the requirement to install it perfectly level and horizontal. A regular building level. To adjust its location taking into account the level readings, use cut strips of plastic or wood chips (the latter only if they have been treated with an antiseptic). To stabilize the window sill, make a notch on each side of the box, going 8 millimeters deep into the wood.

Secure the window sill with self-tapping screws, screwing it to the bottom of the window frame. Fasteners are placed with a two-centimeter indentation from the outer end of the window sill and with a mandatory backing under each washer. It will prevent the self-tapping screw from breaking through the fabric if you overdo it when tightening the fasteners. Don't worry that the fasteners will spoil the overall impression - they simply won't be visible.

How to prepare a double-glazed window

I recommend installing a handle before starting installation work. But the film can be removed later - this way there is less chance of leaving unattractive stripes on the surface of the plastic. You only need to tear off the adhesive strip where the handle is installed. When placing the lever on the sash, hold its long part parallel to the window sill.

After installing the window, this position of the handle will correspond to the mode of opening the entire sash towards itself. When the handle is moved with the end down, the sash will be locked; upward - only the narrow upper part of the window can completely move away from the frame panel.

Having secured the handle to the panel with a pair of bolts, you need to turn it end down. On the side posts, mark the holes for fastenings that will hold the window within the frame.

Window installation

We place the assembled structure in the opening, making sure that on both vertical edges the intermediate distance from the frame to the sides of the glass unit is the same (about a centimeter).

At the same time, remember that the horizontal direction is given to us by the window sill that was previously strengthened in the correct position. If it is inconvenient to use a level due to the presence of decor on the outside of the wall, then use a plumb line.

While the person helping you holds the frame, you must wedge a centimeter-wide spacer bar between the frame and the window frame. Their presence is necessary for the stability of the structure being fixed at the moment of connecting the glass unit to the frame with self-tapping screws. If you are lazy or forget about the bars, you can cause the window to move to the side during the fastening process.

When inserting a self-tapping screw, you need to ensure that its location is in the free space between the window and the frame itself.

Then, during periods when the house “walks” under the influence of climatic influences and seasonal changes, the windows in it will not warp.

Installing a window in a wooden house using a self-expanding tape in the video:

How to install double-glazed windows in a wooden building?

First, take care of maintaining the passage of the drain holes - install adjusting plates between them that will prevent condensation from accumulating from the window.

Then insert the double-glazed window into the opening of the box so that there is free space around the entire perimeter between the two structures. It is necessary to maintain the integrity of the glass in the frame when the frame will move behind the house in the spring or winter.

If the glass unit fits tightly to the frame (minimum gap of 5 mm), file a claim with the manufacturer of the structure. A decent contractor should respond by offering an appropriate solution to the problem.

Having inserted a double-glazed window into the box and aligned the first one on four sides with respect to the last one, secure its location with plastic beads with profile spikes. These “spiky” strips are very easy to install: just push them with small taps into the openings. When the bead's spines reach the grooves, you will hear a characteristic click.

Having achieved a fixed and correct placement of the double-glazed window in the box, fill the voids between these two structures with polyurethane foam, treating the cracks from the inside and outside.

Remove any frozen excess by trimming with a knife.

Having made sure that the work was carried out correctly: the grooves are closed, the sashes move only under the pressure of your hands, you can begin installing additional fittings, trims and drainage systems.

Secure Installation Rules All difficulties with installing windows in wooden houses have one root: instability wooden structures

throughout the entire operational period. IN Without taking this factor into account during the installation of plastic structures, be it windows or doors, it is quite possible to find yourself in a situation where the new “joinery” fails without even working for a year. How do wooden houses differ from others? Wood loses a lot of moisture in the first years after the construction of a log house. A year, as some say, is not enough for the final drying process. best case scenario

On average, the height of the wall can decrease by 4-5 cm. And what will happen to the double-glazed windows that were installed in the box in such a way that there was only 2-2.5 cm between the sides of these structures? Do owners of wooden houses really need to forget about dreams of plastic windows? Of course not. You just need to follow a number of technical recommendations.

First: do not neglect the casing. It is also called a pigtail. Thanks to it, any windows become independent from exposure, within reasonable limits, load-bearing walls building. Whether they shrink or become slightly bent, this will not affect the integrity and functionality of the window.

Are common specifications casing:

  • will protect the logs from moving away from the vertical in the area of ​​the window opening;
  • does not resist vertical shrinkage of the wall;
  • takes on all the loads;
  • contributes to the strength of the wall in the window opening area.

What is casing? The most common option is to make square vertical grooves with a side of 5 cm in the ends of the logs and then seal them with bars of the same size. But such treatment of the walls around the opening is only suitable for preparing a place for wooden windows. To prepare an opening for plastic double-glazed windows, you need to make a ridge at the ends of the logs, and then install a window carriage with a groove on it.

The presence of a tongue and groove will ensure that the logs slide without harming the window frame.

What is a window carriage? These are vertical bars with dimensions of 15x10 cm, with notches on the edges. The depth of the cuts is 5x5 cm, they are made for inserting jumpers topped at the ends with spikes in the form of 15x5 cm planks. The assembled casing is 7-8 centimeters below the window opening. This gap is left due to possible wall shrinkage.

When the pigtail is assembled in the opening, it is then covered with rolled tow, and carriages are stuffed on top. After such a procedure, neither squeaks from shrinkage nor drafts from under the window are scary. Then you need to make the lower jumper and also stuff the carriages onto the comb with tow. Insert the upper jumper into the hole from above, and then lower it into the groove. Then strengthen the structure with self-tapping screws, making sure that they do not touch the ridge - this is important for maintaining the resulting structure’s relative freedom. After

All cracks found between the window frame and the walls must be filled with tow.

The gap between the log house and the casing must be filled with thin strips with wound tow fibers.

When the house begins to shrink noticeably, knock out the planks to replace them with new ones. To make this process easier, I strongly recommend attaching the top casing only to the casing. If you need it, carefully remove it, change the filling, and secure it in place.

When I conducted seminars, I often encountered bewilderment about the need for a window installer to understand the technology of constructing wooden buildings. What's strange about this? Without this, the installer will not be able to install the window in such a way that it will serve for years without complaints. In other cases it is impossible to do without casing.

If you are hired to install plastic double-glazed windows in a wooden house, find out the presence of casing. If it is not there, and instead of a frame there will be a frame from an old window, tell the owner that he has two options. Either he agrees to modernize the window opening for casing and the windows are smaller than planned, or the person will receive windows in old frames without casing, but without your guarantee for a quality result. Since even old wooden houses always “walk” and to resist this, it is better to always take this factor into account when installing windows. And don’t forget to indicate in the contract that you disclaim all responsibility for the future life of the windows.

Remember: everything wooden buildings shrink. And this fact must always be taken into account when installing plastic double-glazed windows in a log house.

The strongest shrinkage processes of wood occur in the first two years after the construction of the log house is completed. Each meter of masonry shrinks by 1.5 cm. And this is a very large value to ignore when equipping a wooden house with plastic windows.

Why do they make a casing?

The durability of the plastic window and the level of comfort during use depend on how professionally the casing is carried out. It provides the window with a safe position during the period when the house is once again slightly deformed due to fluctuations under the influence of changes in humidity or temperature.

What is casing? This is a box made of thick boards. It is inserted into the window opening, secured using a certain technology, and only then they install the PVC double-glazed window. The box itself is held inside the opening using side grooves.

In the process, you cannot rely on the technical qualities of polyurethane foam or other fastening methods.

A gap must be left between the structure and the upper lintel of the window opening, the value of which should be greater than the expected shrinkage of the wooden wall.

How to make a pigtail:

  • tab wooden beams into specially made grooves (screws will then be screwed into the beams);
  • cutting out tenons on the edges of the logs in the window opening and forming grooves in the sides of the box (experts call this the “into the deck” technique);
  • tenons are made in the sides of the structure, and the ends of the window opening logs are equipped with grooves.

Nuances of preparing a window opening

Do not be intimidated by the work of installing plastic double-glazed windows in a wooden building. If you follow the correct algorithm, you can insert modern window in a log house of any age.

First of all, determine the distance to the window from the floor. The most convenient option is if the window sill is slightly higher than the horizontal plane of your desk.

If there is none nearby, then use a distance of 80-90 cm. Determine the lower and upper boundaries of the window opening using a water level. The top line should be 13 +1.5 cm above the top border of the glass unit, the difference on the sides should be 12-14 +1.5 cm.

Leave an allowance of one and a half centimeters to seal the cracks with construction foam. Having decided on the size of the opening, take measurements for the future window. Observe extreme accuracy both when installing the casing and when taking parameters for the design of the double-glazed window itself. Qualitative measurement is one of the most important nuances

, affecting the quality of all subsequent work on the installation of double-glazed windows into the window opening.

After bringing the opening to the desired condition, start tenoning the ends of the logs facing the window. The rough window is trimmed with jute on the sides and bottom. Make the casing only from well-dried wood, sawn into bars. Make connections with self-tapping screws, and cover the points of convergence along the joints with sealant. Fill the gaps in the window with tow.

Installation nuances

The finished metal-plastic structure is placed after being ideally pulled out in the foreground or deepened into the wall. The main product is secured with self-tapping screws, screwing them into specially prepared grooves. It is permissible to install in an ordinary wooden house, but not made of timber metal-plastic window

When selecting tools and other materials, do not take self-tapping screws longer than 12 cm. Such “stings” will definitely go beyond the frame and dig into the main building, which is unacceptable given the mobility of a wooden house.

To waterproof the external seam, you can use acrylic sealant without additional components in the composition, sealing tape that self-expands after being placed in place, or regular vapor-permeable tape.

Such protection will extend the service life of the polyurethane foam and prevent the formation of drafts.
