Do-it-yourself technology for installing plastic windows. Do-it-yourself installation of plastic windows with double-glazed windows in a wooden house Installation of a plastic window in a tree

Glad to be of service 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 have not yet come across such a process, so I made up for the lack of practical experience with the help of other people's knowledge: I “overlooked” a bunch of forums and sites, through friends I found people who had already done similar work. After he made a number of conclusions and determined the algorithm of his actions when reinstalling windows. Next, I will state everything sequentially.

First of all, I measured the windows and ordered new ones, reporting the exact dimensions. While the order was being fulfilled, I started dismantling the old frames, and then cleaning the openings from accumulated debris. Upon receipt of the windows, he installed window sills and prepared double-glazed windows for installation. He put the structures in permanent places and fixed them. Of course, in reality, the process was not so fleeting and easy, but there is nothing overwhelming in it - I did it and you will succeed.

The technology of installing a plastic window in the opening of a wooden house

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

So that the work in connection with 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.

The best option is 6 pieces for each window. They can be ordered in the same place where you give an application for the manufacture of double-glazed windows.

Under these fasteners on each side of the window there are technical slides, 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 the frame when attaching it, which will cause depressurization of the chambers in the profile. Personally, I am against such barbarity - I need windows not only for beauty, but also for reliable protection from cold and moisture. And to the installers, if you do not install them yourself, also tell them to install the windows according to the rules. Only in this case, the expectations from plastic double-glazed windows in a wooden house will be fully justified.

I strongly advise you to remove the window sashes from the frame before installing it in the opening. This will not take much time, but it will save a lot of effort: without them, it will become much easier and it will be easier to direct it to the right place.

The algorithm for installing a double-glazed window in the opening of a wooden house:

inserting the structure into the pigtail, insert wood chips 2 centimeters thick under the lower frame;
using the water level, determine the quality of the installation;
achieve the desired indicator by laying additional chips;
align the frame vertically with the same pieces of wood;
having determined the most optimal position, fix the frame on the pigtail with self-tapping screws, inserting them into the holes on the mounting plates.

When screwing in each self-tapping screw, do not hit the crest of the log against which the pigtail rests. To avoid loosening the self-tapping 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 deflecting under the pressure of the hardening mounting 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.

At the end of the frame alignment horizontally and vertically, a gap of 2 cm thick should remain on each side of the entire structure - for foam filling. The height of the distance between the top panel of the pigtail and the first log is not less than 5 and not more than 15 cm - the gap will prevent the pressure of wood on the windows after shrinkage of the log house.

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

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

Self installation

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

Why did I decide to do my own window installation?

There are several reasons:

for installation, you will have to pay up to 50% of the cost of the window itself (you can buy a third one for the saved money for 2 installed on your own);
almost all companies that provide window installation services in wooden houses do not give any guarantees for their work;
no need to pay for a service that any owner is able to provide to himself for 2 hours of work.

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

Removing old windows

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

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

How to prepare a place

Go around the entire perimeter of the frame with a dry brush or a clean rag to sweep away everything left after dismantling.

Window sill installation

The first to a permanent place is a plastic window sill, which is "imputed" to serve as the basis for the rest of the structure. Hence the “legs grow” of the requirement to install it perfectly evenly and horizontally. To determine how correctly it is installed in a vertical and horizontal position, the usual building level will help. To adjust its location, taking into account the level readings, use chopped strips of plastic or slivers (the latter only if they have been treated with an antiseptic). For the stability of the window sill, make a notch on each side of the box, going deep into the wood by 8 millimeters.

Fix the window sill with self-tapping screws, screwing it to the bottom of the window frame. Fasteners are placed with a two-centimeter indent from the outer end of the window sill and with a mandatory substrate for each washer. It will not allow the self-tapping screw to break through the canvas, if you overdo it when tightening the fasteners. Do not worry that the fasteners will spoil the overall impression - they simply will not be visible.

How to prepare a double glazing

I recommend that you install the handle before starting installation work. But the film can be removed later - so there is less chance of leaving unattractive stripes on the plastic surface. You need to tear off the adhesive strip only at the place where the handle is installed. When placing the lever on the sash, hold it with the 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 moving the handle end down, the sash will be locked, up - only the narrow upper part of the window can completely move away from the frame panel.

Having fixed the handle on the panel with a pair of bolts, you need to turn it end down. On the side racks, mark out the holes for the fasteners with which the window will be held within the frame.

Window installation

We put the assembled structure in the opening, making sure that from both vertical edges the intermediate distance from the frame to the sides of the double-glazed window is the same (about a centimeter). At the same time, remember that the horizontal direction is set by the window sill previously fixed in the correct position. If it is inconvenient to use the level due to the presence of decor on the outside of the wall, then use a plumb line.

While the person helping you will hold the frame, you must wedge a centimeter-wide spacer bar between the box and the window frame. Their presence is necessary for the stability of the fixed structure at the moment of connection of the double-glazed window with the frame with self-tapping screws. If you are too lazy or forget about the bars, you can provoke the window to go to the side in the process of fixing. As a result, then the sash will be difficult to open and close.

After wedging in the bars and placing the double-glazed window strictly according to the level indicators, fix the inserted structure in the box with self-tapping screws, not forgetting to screw them on each of the four sides.

When introducing a self-tapping screw, you need to ensure that its location takes place in the free space between the window and the box itself.

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

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

First, take care of maintaining the patency 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 box will lead in the spring or winter after the house.

In the case of a tight fit of the double-glazed window to the box (minimum gap of 5 mm), file a claim with the manufacturer of the structure. A decent contractor in response should offer an appropriate solution to the problem.

After inserting the double-glazed window into the box and aligning the first on four sides with respect to the last, fix its location with plastic glazing beads with profile spikes. These "spiky" strips are very easy to install: it is enough to advance them with small taps into the openings. When the spines of the glazing bead 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 mounting foam, processing the cracks from the inside and outside.

Remove any hardened excess with a pruning knife.

After making sure that the work has been carried out correctly: the grooves are closed, the wings move only under the pressure of your hands, you can proceed with the installation of additional fittings, platbands and drainage systems.

Rules for secure installation

All the difficulties with installing windows in wooden houses have one root: the instability of wooden structures throughout the entire operational period. Without taking into account this factor in the process of installing plastic structures, even window or door, it is quite possible to find yourself in a situation where the new “carpentry” fails without even a year of work.

How are wooden houses different from others? Wood loses a lot of moisture in the first years after the construction of the log house. A year, as some say, is not enough for the final drying process. In the best case, the walls of the house will take the final size in the sixth year after their construction. But in some regions, the process of "walking" houses never ends.

On average, the height of the wall can decrease by 4-5 cm. And what will happen to the double-glazed window, which was installed in the box in such a way that there were only 2-2.5 cm between the sides of these structures? Do the owners of wooden houses need to forget about the 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 gain independence from the impact, within reasonable limits, of the bearing walls of the building. Whether they shrink or acquire some curvature, this will not affect the integrity and functionality of the window.

General casing specifications:

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 over all the loads;
contributes to the strength of the wall in the zone of the window opening.

What is a siege? The most common option is to make square vertical grooves with a side of 5 cm at the ends of the logs and then seal them with bars of the same size. But such processing 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 at the ends of the logs, you need to make a comb, and then install a window carriage with a groove on it. The presence of a ridge and a groove will ensure that the logs slide without harming the window frame.

What is a window carriage? These are vertical bars with parameters 15x10 cm, with notches at the edges. The depth of the cuts is 5x5 cm, they are made for inserting jumpers crowned with spikes at the ends in the form of boards 15x5 cm.

The assembled casing is 7-8 centimeters below the window opening. Such a gap is left due to the possible shrinkage of the wall. When the pigtail is assembled in the opening, it is then covered with rolled tow, and gun carriages are stuffed on top. After such a procedure, neither squeaks from shrinkage, nor drafts from under the window are terrible.

Then you need to make a lower jumper and also fill the gun carriages on the comb with tow. Insert the upper jumper into the hole from above, and then lower it into the groove. Then reinforce the structure with self-tapping screws, making sure that they do not touch the ridge - this is important for maintaining the relative freedom of the resulting structure. Later all the gaps found between the pigtail and the walls must be filled with tow.

Metal-plastic double-glazed windows can also be inserted into such a design, without fear that they will jam when the house shrinks. When installing, do not forget that noise, heat, and vapor barrier also need to be taken care of.

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

When the house begins to shrink noticeably, knock out the planks to replace them with new ones. To facilitate this process, I strongly recommend attaching the upper casing only to the casing. It will take - carefully remove it, change the filling, fix it in place.

When I taught seminars, I often encountered bewilderment about the need for a window fitter to understand the technology of building wooden buildings. And what is 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 any complaints. In other cases, you can not do without casing.

If you are hired to install plastic double-glazed windows in a wooden house, find out if there is a casing. If it is not there, and instead of a pigtail there will be a box of an old window, tell the owner that he has two ways. Either he agrees to modernize the window opening for casing and windows 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 are always “walking” and resisting this, or rather, this factor should always be taken into account when installing windows. And do not forget to indicate in the contract that you disclaim any responsibility for the future life of the windows.

We put plastic double-glazed windows in a private house

Remember: all wooden structures 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 completion of the construction of the log house. 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 do a squabble?

The durability of the operation 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 a siege? This is a box made of thick boards. It is inserted into the window opening, fixed according to a certain technology, and only then they are engaged in the installation of PVC double-glazed windows. The box itself is held inside the opening with the help of side grooves.

In the process, one cannot rely on the technical qualities of mounting foam, other fixing methods.

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

How to make a pigtail:

inserting wooden beams into specially made grooves (then self-tapping screws will be screwed into the beams);
sawing spikes on the edges of logs in the window opening and forming grooves in the sides of the box (experts call this technique “into a deck”);
spikes are made in the sides of the structure, the ends of the logs of the window opening are equipped with grooves.

The 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 right algorithm, you can insert a modern window into a log house of any age with your own hands.

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 be guided by a distance of 80-90 cm.

The lower, upper boundary of the window opening is determined using the water level. The top line should run 13 +1.5 cm above the upper border of the double-glazed window, the difference on the sides should be 12-14 +1.5 cm. Leave one and a half centimeters of allowance for sealing cracks with building foam.

Having decided on the size of the opening, take measurements for the future window. Observe the utmost 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 that affects the quality of all subsequent work on the installation of a double-glazed window into a window opening.

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

See the video for casing and pigtail when installing PVC windows in a wooden house:

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 fixed with self-tapping screws, screwing them into specially prepared grooves.

It is permissible to install a metal-plastic window of any configuration in an ordinary wooden, but not made of timber, house, if you know how to properly frame, take measurements and select the appropriate fittings.

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

For waterproofing the external joint, you can use an acrylic sealant without additional components in the composition, a sealing tape that self-expands after being placed in place, or a conventional vapor-permeable one. Such protection will extend the life of the mounting foam and prevent the formation of drafts.

A vapor barrier tape is placed along the inner seam, fixing it with a special glue. And only then they process the seam with mounting foam.

Repair work in a wooden house differs significantly from similar buildings in a different form. Most companies do not provide a guarantee for installations carried out here, especially windows. Isn't this a reason to think about DIY installation? Armed with a step-by-step video, you can achieve a high-quality result, significantly saving the family budget.

Features of installing a window system in a wooden house

There are many prejudices about wooden houses. The service life of the windows installed here depends entirely on the quality of the building itself and compliance with the technology of the installation process.

You can not start working with a window opening in a new wooden house right away. In order to avoid deformation in the future, it is recommended to wait some time for the structure to stand, the wood to dry out, excess moisture to evaporate from it, and the walls to become static. Thus, the chance of mowing the opening is minimized.

As a place for a window, do not choose the outer part of a wooden house. The opening can be in the center or closer to one of the corners, but not in contact with it.

Window cutting pattern

The installation process itself is not too laborious: it can be carried out with one pair of hands in a few hours. The subtleties of the preparatory work depend on whether the windows have already been installed before or whether the casing needs to be created from scratch. A similar technology can be used to install PVC in any wooden building: a bathhouse, a gazebo, etc.

Preparing the Workspace

For hand-made installation of plastic windows, you need a reliable base - a frame. If the previous windows were installed within the last few years, did not have time to acquire physical damage and rot, then you can use the box from them as a frame for the new system. With this option, measurements are made according to the new size of the opening, focusing on the preserved box.

If PVC is installed in a new building, then you will have to take care of the pigtail. This is the name of the design that prevents the window system from deformation. There are several types of it:

With a mortgage bar;
In the groove of a log wall;
On a spike in the wall;
With a quarter.

Mowing a window opening is one of the necessary steps for installing a plastic window in a wooden house

Using a rag, you can remove dirt, dust and start measuring. The reliability and expediency of carrying out all further work depends on their accuracy: inattention at this stage can jeopardize the entire installation.

Advice. If the opening is distorted, then to create a plan with measurements, they are guided by the supposedly correct geometric shape and right angles, and the deformations are removed with a sealant or ordinary putty.

Window sill installation and window preparation

It is the basis of the entire window system, so its installation must be carried out with a level: the horizontal surface must be ideal from both the longitudinal and transverse positions.

To do the work with your own hands, the following algorithm of actions is used:

Small recesses (at least 5 mm) are made in the window box for additional fixation of the window sill.
Using plates made of fiberboard, plastic or wood treated with an antiseptic, level the level of the window sill.
With the help of self-tapping screws, the installation of the window sill is carried out. A gasket or washer must be placed under the caps to prevent cracks. For self-tapping screws, you need to choose a place where they will be hidden by a future window. Usually, it is located at a distance of 2-4 cm from the end.
After installing the window sill, its horizontalness is checked using the building level.

In general, installing a pvc window in a wooden house does not cause any particular difficulties if you familiarize yourself with all the nuances of the work in advance

As for the window itself, it is necessary to attach the handle in the downward position (closed state) before installation.

Attention! There is no need to remove the protective film completely: just open it slightly at the place where the handle is attached.

Window installation

Installing a window in a prepared area of a wooden house is no different from installing it in another structure. The process is performed in the following sequence:

Marking the window frame and drilling mounting holes. The procedure is performed using a 6 mm drill for the corresponding self-tapping screw 1 mm smaller in diameter.
Installation of the system in the opening. At the same time, they are guided by the window sill, the even level of which, thanks to additional control, is beyond doubt. The center is determined using a centimeter tape.
Level relative to the wall. To make the window parallel to the wall surface, use a plumb line. If it is trimmed with siding, which allows you to place a level between the trim and the wall, then you can use it.
Fixing a bar that would completely fill the space between the window and its frame. It will become the focus for further installation. Installation without it may lead to overlapping of the window opening-closing mechanism.
The window is fastened with self-tapping screws from the bottom and top of the side posts, so that they do not interfere with the free opening of the window in the box.
Foaming of cracks and removal of its excess.

Installing a PVC window with your own hands can save up to 60% of the family budget. Following the detailed instructions for their installation will make the structure resistant to seasonal tree deformations, extending the life of the system for a long time.

As practice shows, plastic windows (PVC or euro windows with double-glazed windows) have higher energy saving rates than ordinary wooden ones. For this, as well as for a number of other reasons, more and more often PVC windows are preferred during the construction or reconstruction of a wooden house.

Of course, this is a controversial preference, however, we will not figure out which windows are better - wooden or plastic.

In this article, we will consider how to independently install plastic windows in a wooden house (as well as a log or timber frame). Let's do this using the most common installation method as an example.

The window installation process consists of several stages:

Dismantling old windows in a wooden house
Preparing openings for installing new windows

The disassembly process, most often, does not present any particular difficulties. To work, you will need a saw (chainsaw, electric saw), an ax, a nail puller or a crowbar.

If the windows are old and the window casings are rotten and useless, then you can ruthlessly destroy everything and everything, not caring about the safety of the latter.

If the window frames are in good condition, then carefully remove them, after removing the glass. These frames can serve as a greenhouse, gazebo or other construction needs.

When dismantling old windows, be sure to observe safety precautions when working with cutting and chopping tools, use safety glasses when working with saws. Before sawing the structure, make sure that there are no nails or any metal pins - this will save the tool (saw band) and protect against possible injuries, since when the saw is jammed, it is quite difficult to hold it in your hands.

Preparing openings for installing new windows

After removing the frame, you need to make sure that the window opening is suitable for installing a new window. Namely, check the condition of the wood of the window frame, the absence of traces of rot, wormholes, cracks, chips and other damage. It is recommended to treat it with protective compounds. If the window frame is not suitable for further use, then it must be replaced with a new one. To do this, you need a good, dried planed board. The corners can be fastened with locks (for example, a tongue-and-groove), or you can simply twist them on self-tapping screws of sufficient length. Be sure to treat the structure with protective compounds.

When replacing a window frame, it is possible to carry out an audit and, if necessary, replace the vapor barrier, insulation materials, check the condition of the material (wood) in the window opening of the wall.

You may need to replace some sections of the opening. For example, in log houses, the areas of logs located under the window opening most often suffer. In this case, the damaged areas are cut out and replaced with pieces of logs of a suitable size. The replaced sections are fixed, depending on the possibilities, with brackets, long screeds, wooden locks (groove-thorn).

Be sure to treat the replaced area with protective compounds.

Installation of windows in a window frame (for logged wooden houses, the installation of a window frame is carried out by means of a pigtail or casing) is the most correct way to install windows. Thus, the rigidity of the opening is maintained, and a strong base frame is created. But at the same time, the window itself will be able to self-regulate with seasonal fluctuations in the house (shrinkage, movement, etc.).

During installation, the window frame is set according to the level.

Installation of plastic windows in a wooden house

After the preparation, we proceed to the process of installing the window itself.

First of all, we disconnect the window frame from the sashes, if the window is deaf, we take out the double-glazed window. We do not remove the protective film from the windows - it will protect the profile from possible damage and scratches.

Window sill installation

If you want to install a window sill, then first of all we mount it. When installing, we adjust the plane using a level and backing plates (pieces of wood, plywood, etc.).

If the window sill is also made of PVC, then a washer must be placed under the head of the self-tapping screw (so that when tightening the self-tapping screw, it does not fall into the cavity of the window sill). We screw the screws into the places located under the future frame (so that it is beautiful and the hats are not visible). But most often, the lower wide board of the window frame serves as a window sill, and therefore the installation of an additional window sill is not required.

Frame fitting

We put the frame on blocks with a thickness of about 1 cm, we check the level of correct installation. On the sides, be sure to leave a gap of at least 1 cm, install the bars between the frame and the window box. They will prevent the frame from moving horizontally, prevent possible deformation of the frame during installation, and allow the window frame to be securely fastened to the window frame.

We check the plane of the surface of the wall (window box) and the frame, not allowing the frame to protrude beyond the boundaries of the window box.

Window frame installation

We fasten the frame with long self-tapping screws to the window frame, trying not to overtighten the self-tapping screw. After installing the frame, we hang the sashes and install double-glazed windows (in blind windows).

When installing a double-glazed window into a profile, it is necessary that there is a gap of about 5-7 mm between the double-glazed window and the profile. This will prevent the glass from warping and cracking in case of possible deformations of the profile (frame) during operation (seasonal fluctuations of the building, possible distortions during shrinkage and during operation).

Vertical adjustment is made by adjusting plates.

Installation of a double-glazed window

Further, with the help of a plastic glazing bead, the double-glazed window is fixed in the PVC profile. The glazing bead spike should click into the groove on the frame. The connection should be made by lightly tapping the glazing bead with a wooden or rubber mallet or hammer.

window foaming

Next, we foam the space between the window frame and the frame. We wait until the foam hardens. During this period of time, it is not recommended to open or set the window for ventilation in order to prevent deformation of the frame from the expansion of the foam.

After the foam hardens, we cut off the excess and you can proceed to trimming with platbands.

The last step is to remove the protective film, the window is ready for use.

Plastic double-glazed windows have gained popularity because of their performance. But can they be used in the construction and repair of wooden buildings? Of course, you can and should.

Installing plastic windows in a wooden house has a lot of differences and features. The process includes a number of preparatory manipulations, primarily related to the fact that the structure tends to sag over time.

We install a PVC window in a private house

Features of the technology for installing PVC windows in a wooden house of a new or old building do not have a strong difference. In any case, experts recommend technology using casing - time-tested, this technology allows you to avoid deformation, regardless of the material from which it is made.

Installing a plastic window in a wooden house or cottage with your own hands will require some knowledge and skills from the performer. Of course, if there are none, then it is better to turn to specialists. The complexity of the self-assembly of PVC systems in a wooden house lies in the fact that the frame is attached using the tongue and groove mechanism. This design allows you to create such operating conditions in which the deformation and subsidence of wood does not have a direct effect on the double-glazed window.

The system allows you to install a plastic window yourself, so that the window is fixed independently of the main wall structure and has a floating character. The window system is fixed with the help of grooves on the side, which are mounted on spikes protruding from the end of the logs and timber.

To fix and seal the casing, only tow, linen or fiber insulation is used. In any case, mounting foam.

Attention! A gap is left at the top based on the draft of the wood.

Thus, the shrinkage of the walls of a wooden structure in no way affects the window and, moreover, will not damage it. Depending on the fasteners, casings can be classified into the following types:

into a spike. Such a design is characterized by the presence of a spike, which is mounted on the side parts of the casing, and a groove, which is located in the logs of the opening;
in a mortgage bar. The basis of the fastening is a bar, which is placed in a groove at the ends of the opening and passes through the casing posts;
into the deck. The spike is located at the ends of the logs of the window opening, but the groove is in the casing posts.

The box is a floating mechanism that excludes deformation of the plastic window during operation, regardless of the type of casing installation.

Calculations should be made with high accuracy, since even a slight error can lead to deformation of the window frame or leakage of the structure. In addition, proper installation is a guarantee of the quality of the plastic window itself.

How to make a pigtail (casing)

The design can be of two types: complex and simple. A simple pigtail is the system described above, with bars and grooves. The complex design is performed somewhat differently: a comb is cut out in the window opening, on which a carriage with grooves is put on. This option is more reliable. When the walls shrink, the comb can slide and does not allow vertical deviations, excluding pressure on the window frame.

The casing, as a rule, is made of timber. Using a wood chisel, a 0.5 cm groove is knocked out in the center of the beam, and a spike (0.5x0.5x.25 cm) is cut out from one end. A comb with spikes 0.5x0.5 cm is cut from the end of the opening logs. To do this, you can use a saw or a chisel.

Important! Ridge marking is an important point. The quality and reliability of the design depends on the accuracy of the markup.

After the comb is ready, we proceed to install the risers and form the opening structure between them. The bars are set according to the level, taking into account the gaps for shrinkage of the walls (1 cm on the sides and 0.5 cm on top). The frame of the bars is strengthened with the help of grooves with the main canvas of the walls and dowels between them. The gaps left are sealed with tow or other fiber. That's all, now you can proceed with the installation of the plastic frame itself. You can see the process in more detail in this video:

Stage number 3. Installation in the prepared opening

After carrying out the necessary preparatory work and installing the pigtails, you can proceed with the installation of the window.

Attention! Installing plastic windows in a wooden house without casing is the wrong option.

To begin with, we check the dimensions and location of the parallels, the gaps between the casing and the frame. The stock for foaming should be: 4-5 cm at the top, 2-3 cm in width and height, 3-4 cm in the window sill area. After making sure that the stock corresponds to these indicators, we proceed directly to the installation of a plastic frame.

The window is fastened with special fasteners, which are sold at any hardware store. They are metal plates with holes.

Installation of a plastic window should be carried out according to the level. If you neglect this factor, then you risk getting a tilted design, which significantly reduces the operational and aesthetic objectives of the window.

Advice! Before installing the window, the sashes are removed. This facilitates the design and it is much more convenient to mount it in the opening.

After the window is fixed in the opening, it is necessary to fill the gap with mounting foam. To avoid displacement of the structure during foaming, bars are placed that will maintain the position of the frame without deviations. After drying, do not forget to remove it.

Securing the window in the casing is done with care. In this case, it is necessary to choose the correct location for tightening the screws. Under no circumstances should a window be fixed in the ridge area!

That's all, we finish the process by completely foaming the opening. We put on the sashes and let the foam dry.

We have presented the correct way to install a plastic window in a wooden house. This process can be difficult, so if you are unsure of your abilities, it is better to turn to professionals.

However, installing a plastic window with your own hands is a significant cost savings. We offer you to watch a video instruction for installing a window with your own hands:

Every reader of the site knows that no matter what material the windows are made of, they help keep the heat in the house 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 a wooden, frame and stone house.

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

From our article you will learn:

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 installing a plastic window;

How to control the installation process.

Preliminary preparation

Despite the seeming 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 house. Here's where the process starts:

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

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

A set of a professional installer has about a hundred different "tools". It is not necessary to have all of them, but without a basic kit, it will not be possible to install a translucent structure. It includes: puncher, screwdriver, foam gun, chisel, hammer and screwdrivers.

When choosing tools, it should also be borne in mind that window installation involves a wide range of additional work.

These include:

Plastering slopes in stone buildings;
Seam and thermal insulation device;
Installation of a window sill and additional accessories.

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

Anatoly Gavrysh Head of the design bureau of the company "Fabrika Okon"

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

We install wooden windows with our own hands

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

Anatoly Gavrysh:

There is practically no difference between the installation of a plastic and a wooden window. A slight difference lies only in the different elements of fasteners.

Do-it-yourself installation of a wooden window should be carried out 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 the work it is necessary to adhere to the recommendations of GOSTs, namely:

Mounting window seams - with vapor-permeable self-expanding tapes;
Specifications, GOST R 52749-2007;
Assembly seams of knots and adjunctions of window blocks to wall apertures;
General specifications, GOST 30971-2002;
Window blocks - from polyvinylchloride (PVC) profiles. GOST 30674-99.

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

Opening preparation;
window preparation;
Installation;
Finishing work;
Finishing.

I would like to dispel the illusions about the ease of installation of both plastic and. To carry it out on your own, you definitely need certain skills and special equipment, since proper installation is of decisive importance in how well 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. 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 clearance (reserve) 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 with a width of 20 mm. In the lower part of the window - under the window sill, it is recommended to lay a margin of 35 mm.

3. The design is fixed.

Fixation is carried out using dowels or special mounting gear plates. If the window is fastened through with self-tapping screws, then before that, holes for the anchor 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. An indent of 12-15 cm must be laid from the corners of the frame.

4. Foaming of the seams between the window structure and the opening is carried out.

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

5. The foam is closed with vapor and waterproofing tapes.

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

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

7. The fittings are being 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 the change in the design of 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 - every 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.

Proper windows in a wooden house.

Here is what we can do to protect structures from possible deformations caused by wall shrinkage using the old carpentry method:

Anton Karyavkin

The most responsible builders start cutting an opening in the 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 features of the region.

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

Alexander Korpachev

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

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

Anton Karyavkin

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

Despite the fact that the box quite effectively perceives the deformation of logs, the assembly 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 needed to protect the assembly joints must also have a high class of deformation resistance.

Glued laminated timber shrinks much less than solid logs. As a result, glued laminated timber deforms less than a regular log.

But installing windows in a wooden house with your own hands is still difficult.

How to lay a window in a frame house

Wooden windows can also be installed in a frame house, but plastic windows are most often used. The 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 face the deformations of the window opening, but they are no longer so significant.

As fasteners, it is better to use anchor plates. Mounting on building screws is not recommended: they fix the box, and the deformation of the tree, 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 frame from a room, it must be wrapped into a window opening. This is necessary in order to connect the window vapor barrier circuit with the room vapor barrier circuit.

Brick of various types, concrete, aerated concrete blocks are standard building 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, the installation technology may be influenced by design decisions that require taking into account the linear dimensions of the structures and the wind load in the region.

Protection of mounting joints and stages of control of installation work

Regardless of the material of the walls, it is necessary to protect the mounting 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 close any gaps and irregularities, unlike mounting tape, which requires a perfectly flat surface without dust.
