How to fix a window: an overview of the fixing hardware and a photo report on the installation. How to install a plastic window in a wooden house on your own Step-by-step installation of plastic windows in a wooden house

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 wooden house(as well as a frame made of logs or timber). Let's do this using the most common installation method as an example.

The window installation process consists of several stages:

  1. Dismantling old windows in a wooden house
  2. 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, 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 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 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 frame deformation from foam expansion.

After the foam has hardened, 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.

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, informing 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.

Most best option- 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 wood pressure 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 go further on its own 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 summary of my experience in self-assembly double-glazed windows in a house from a bar.

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 adhere to the recommended below step by step algorithm actions.

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 determined 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, which 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 mounting foam, processing slots 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: instability wooden structures throughout the entire operating 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 receive independence from the impact, within reasonable limits, bearing walls building. Whether they shrink or acquire some curvature, this will not affect the integrity and functionality of the window.

General specifications casing:

  • 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. Then 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 operation depends on how professionally the casing is carried out. plastic window and user comfort level. 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 PVC installation double-glazed window. 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:

  • tab wooden beams into specially made grooves (then screws will be screwed into the bars);
  • 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. Quality measurement is one of the most important nuances, affecting the quality of all subsequent work on the installation of a double-glazed window in 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.

Inserting a plastic window into a wooden house is not as difficult as it might seem: with the knowledge of some technical subtleties, it will be quite within the power of a non-professional. It must be remembered that wood is a special living material, and all work must be carried out taking into account the future shrinkage of the house. Therefore, the technology for installing a plastic window in this case will be somewhat different from standard installation. Let's consider each stage in detail.

Creating and preparing a window opening

How to insert a plastic window in a wooden house? The success of the work depends, first of all, on a well-prepared opening: most often it is cut through in a wooden house after the log house has been assembled, but sometimes it is done even at the construction stage. In the first case, it is possible to proceed to the preparation of openings only after the completion of the main shrinkage, that is, a year and a half after construction. The contours of the hole are drawn with a plumb line and a level, after which they are cut very carefully with a chainsaw.

It is advisable to apply the markup even at the stage of assembling the house, so that there are no pins in the places of the openings. The calculation is made so that the upper and lower logs are cut in half: this will allow you to calmly install the casing to even horizontal surfaces. When preparing the opening, it is necessary to take into account the size of the casing. Therefore, in width it should be more sizes frames by 14 cm, from above - at least 12–14 cm more, from below - by 7 cm for installing a window sill and a layer of mounting foam.

If the opening is prepared at the assembly stage, it should be 10% less in width than planned. This is necessary, after the logs have dried, it will take the specified value. If you immediately give it standard size, after shrinkage, it will be more than necessary.

Before inserting plastic windows into a wooden house, you should carefully process all the end parts of the logs, cover them with an antiseptic to protect them from decay. In addition, the wood must be sanded so that the surface is smooth. Often it has to be leveled in height: wooden houses rarely remain perfectly even after shrinkage. In order for the frame to fit correctly, the hole must be leveled with a laser level and a plumb line.

Casing box installation

If you want to understand how to correctly insert plastic windows into a log house, it is important to understand the installation of the casing. This design is also commonly called a pigtail: it is designed to protect window hole from the effects of shrinkage. The pigtail is an additional frame that is mounted to the end parts of the opening logs according to the sliding principle: the logs will gradually descend along it and will not harm the frame.

To create a movable connection, several mounting options are possible:

  • A rectangular groove 5 cm wide and 5 cm deep is cut out in the end part of the logs and in the side parts of the casing box. A bar of the same size wrapped with insulation is inserted into it. When lowering the logs, they will gradually slide along the bar, while the casing will remain in place, and the window blocks will not suffer.
  • A groove is cut out in the logs with a depth and width of 5 cm, and a T-shaped design of a pigtail made of timber is inserted into it. The spike should fit snugly into the groove; to get rid of the creak, it is wrapped with a heater.
  • There is also a reverse option: a spike is cut out in the logs of the opening, and a pigtail groove is mounted on it.

In all cases, vertical elements are placed first, the upper and lower horizontal boards are mounted to them. In some cases, the pigtail is installed without the bottom. A gap of about 7 cm is left above the top board: it will gradually decrease as the walls are lowered and disappear completely in a few years. For a while, it is filled with insulation so that the heat does not go outside.

The casing box must not be installed on mounting foam, it must not be used to fill the upper gap. This is an inelastic material, it will not compress, so the casing will simply lose its meaning and will fall along with the house itself, breaking the frames.

The pigtail, like other wooden elements, is treated with an antiseptic. After the protective layer has dried, it is ready for the installation of a plastic block.

Design selection criteria

When deciding how to correctly insert plastic windows into a wooden house made of timber or logs, it is necessary to study the proposals of manufacturers. Plastic window systems are selected according to several parameters:

  1. The number of chambers in the profile determines the thermal efficiency. Manufacturers offer three-, four- and five-chamber profiles. A four-chamber will be quite enough for the conditions middle lane: thanks to the air gaps, it will not freeze and will be strong enough.
  2. Glass unit type. The more air chambers and sheets of glass in it, the more powerful heat insulator it will be. However, triple-glazed windows are very expensive, while they are heavy and require high-quality fittings.
  3. Hardware type. You can not save by choosing a set of accessories. The performance of the handle, the ability to choose operating modes, as well as the strength of the frame itself depend on it. If choose cheap option, very soon the window will begin to sag and it will be difficult to close.
  4. Manufacturer. Classic option guaranteeing great quality, are considered the original German systems Rehau, KBE and others. However, their full counterparts are now being manufactured in Russia, which are much cheaper. In addition, we must remember that it is more profitable to purchase any products and designs directly from the manufacturer, in this case they cost a much smaller amount.

In addition to the frames themselves, you need to purchase handles, ebbs, window sills, additional accessories, as well as trim that will close the mounting seam. Typically, installers offer along with window block complete mounting kit. It can be supplemented with anti-burglary fittings, special child locks, a “comb” for ventilation, etc.

Window sill installation

Dust and debris are removed from the opening with the casing already installed, the surface is cleaned. After that, they put the window sill: it is the basis for the window, so you need to mount it as evenly and accurately as possible. To install it, you need to make 8 mm cuts in the window box, the window sill itself is attached to the bottom of the casing or the lower log with self-tapping screws. It is advisable to put special washers under them so that the plastic does not start to crack.

The window sill must be strictly horizontal, so after installation it is checked with a building level. If there are any deviations, plastic or wooden wedges are placed under it.

After mounting the frame, the attachment points of the self-tapping screws will be invisible, they will be completely hidden by the box. The window sill can be not only plastic: it is made of natural or artificial stone, wood, and other materials.

Frame assembly

How to insert plastic windows in a wooden house? When everything is finished preparatory work, you can proceed directly to the installation of the window system. protective film it is not removed from it until the very end of the process, this is guaranteed to protect it from damage. A handle is pre-attached to the frame, as shown in the instructions attached by the manufacturers, sashes with double-glazed windows can be removed during installation, it is much easier to work with an empty box.

The installation process is as follows:

  1. In the side posts of the casing and in the side parts of the window, 4 holes are drilled for installing fasteners. The distance from the top and bottom edges to the hole should be 25–30 cm, such an arrangement of the fasteners will ensure an even distribution of the load.
  2. The window frame is placed in the opening, after which it is leveled with the help of a building level, a plumb line and spacer bars. When it takes a perfectly flat position, it is attached to the casing with long self-tapping screws.
  3. Important! Self-tapping screws should not go through the casing and twist into the wall. The block is attached exclusively to the casing, otherwise its installation will be useless, and the plastic block will suffer from shrinkage. The casing is movably connected to the house, and the logs will gradually take their places, while the window frame must be stationary.

  4. Doors with double-glazed windows are placed in the box. It is important to make sure that the frame is not skewed, the sashes open and close freely and clearly.
  5. After all checks, the spacer bars are removed, and the space between the casing and the box is filled with mounting foam. After drying, it will provide an airtight mount and will reliably protect your home from the cold.
  6. The last stage of work is the installation of a low tide: it will drain rainwater from the wall and prevent dampness from entering the house. The ebb is cut off to right size and attached with self-tapping screws. The seams filled with polyurethane foam are closed with decorative platbands.

Knowing how to properly insert double-glazed windows in a wooden house, you can completely glaze the building without resorting to the help of specialists. Plastic window structures correct installation they serve for a long time and perfectly protect the building from the cold, and it is not so difficult to cope with this work.

The thickness of the mounting foam layer should be at least 2 cm, you can not save on it. For greater reliability and tightness of the connection, the space under the window sill can be smeared with a special silicone sealant. This is good additional protection from blowing.

In any case, the mounting foam will have to be closed from sunlight: it collapses under the influence of ultraviolet rays. Help carved architraves or decorative shutters, which can be an important element of home decoration.

Everything installation work it is recommended to carry out at positive temperatures. Plastic changes its structure when severe frosts: At -10 and below, it becomes brittle and can be damaged very easily. To avoid unnecessary problems, choose the right time for installation.

Installation of plastic window blocks requires increased attention to the correct angles, compliance with vertical and horizontal lines. Even a slight misalignment in the future can lead to an increased load on the fittings, which will negatively affect the operation of the entire structure. If the sashes turn out to be skewed, they will begin to creak and close poorly, and the hinges will quickly become unusable.

And once again: the installation of windows cannot be dealt with immediately after the construction of a wooden house, even if it is being built from dried lumber. It will take at least six months for the logs to finally take their places, then the installation will be safe.

You can find out detailed and extended information on the topic of the article from the book "Wooden Houses", which reflects all the stages of building a house, from laying the foundation to the roof. The price of the book = 77 rubles.

It is known that wooden windows in houses built from timber are rightfully considered the safest and most practical solution favorably affecting the microclimate in the dwelling.

Fundamental in the presented case is that when it shrinks, the window system and walls behave uniformly. The decisive role here is played by their installation according to technology.

Features of installing windows in a wooden house

The assembly of windows in a timber structure has certain features. As you know, wood shrinks. In houses made of chopped logs or during the first 5 years, shrinkage is about 10-13% of the height of the building, while it shrinks no more than 2%.

If there is warping of window structures, the formation of interventional gaps in the walls or cracking of a double-glazed window, this indicates a violation of the technology during the installation process.

  1. In houses made of chopped wood, logs, planed or profiled timber, it is advisable to install a window support after shrinkage of the house (not earlier than 1.5 years after construction).
  2. The installation of windows after the construction of the log house is not rational due to the lack of the possibility of calculating the shrinkage of the walls. This indicator depends on the moisture content of the timber.
  3. In houses made of glued laminated timber, windows can be installed immediately after erection of walls and installation of a roof of the house.
  4. The installation of windows must be carried out exclusively by means of sliding joints - support bars and casing. Tying window blocks and pigtail construction to logs or timber is strictly prohibited. Tight fastening during shrinkage leads to a violation of the integrity of the window modules and walls of the building. In fact, the window system must balance separately in relation to the wall.
  5. In the upper part above the window frames, it is necessary to provide for a shrinkage margin - a gap of 6-7 cm. Miscalculations of spare gaps can lead to poor closing of windows or interventional gaps in the walls.


Scheme of installation of wooden windows

Window opening preparation

Before mounting the box, prepare a window opening. The opening should be rectangular in shape without cracks, recesses, distortions and other flaws. From all its surfaces it is necessary to remove construction waste, dirt, dust and deposits.

In order to avoid distortions in the future, accurate measurements of the external, internal and lateral sides of the opening are required.

In the case when the distortion of the opening is significant, and it is not possible to correct it, it is recommended to expand the parameters of the window in such a way that the highest level of the outer opening exceeds the width by 2.5-4 cm, and the height by 1-2 cm.

To carry out the extension makes it possible to install an additional profile on the window. This will prevent the appearance of gaps between the box and the hole in the areas of maximum skew.

In addition to the option of expanding the size of the opening to correct the skew, there is such an option as increasing the parameters of the window frame.

siege

A special design, which is a wooden box without a bottom crossbar, the purpose of which is to securely fasten the window and maintain the shape of the window frame, regardless of the degree of shrinkage of the house, is called casing or pigtail.

There are several types of this design:

  1. Whole. It is made from specially processed solid material.
  2. Adhesive. The individual components are made of typesetting boards, connected by means of micro-grooves and glue. All burrs and small knots are removed.
  3. Mixed. Part of the casing is made in one piece, and the other part is made using glue. Upon completion of installation, the pigtail is varnished. This type is suitable for the use of large window sills.

An okosyachka is made according to the size of each window. Moreover, if internal lining is planned, then a sample can be made for it. When facing on both sides, sampling is not performed.

The assembly of the casing can begin after the preparation of the window opening.

Its production is carried out as follows:

  1. Grooves are made in the base, which is adjacent to the window opening. A beam of the same size is inserted into them, acting as the side of the casing.
  2. First, a beam is placed at the bottom of the opening, which will prevent the displacement of the side elements.
  3. A seal is placed under the beam from linen tow.
  4. Sealing material is placed in the recesses and install the side boards.
  5. The final step is fixing the top board of the structure.
  6. A space is left on top of the pigtail for the wood to dry out and fill it with a sealant. So in the process of drying the logs, the window opening will not be affected by the load.

Window installation

The window is installed in the following sequence:

  1. A waterproofing layer is laid on the lower part of the opening. and sealing material.
  2. Install the window frame and fix it with the help of linings or wedges made of wood.
  3. Using a building level or plumb line, adjust the horizontals and verticals. In this case, attention should be paid to the actual horizontal and vertical, and not to the sides of the window opening.
  4. On each side of the opening, in increments of 50 cm, drill holes.
  5. With self-tapping screws fix the box.
  6. Perform isolation of the space between the box and the wall sealing material.
  7. Next, mount the frame. It is installed in the grooves of the box and attached to it with screws.
  8. Window blocks are installed on the box with hinges(separable and inseparable). The difference between them is the possibility of removing the hinge. Detachable are convenient in areas where there is no possibility of raising the window transom. Even fastening of the hinges contributes to the even hanging of window transoms. They are fastened with screws.
  9. The sash is locked by means of a locking element or a latch. After checking the opening and closing of the transom, fix the frame using nails.
  10. Next, proceed to the installation of window sills. They are mounted from the inside so that the side edges go into the walls by 4.5-5 cm on both sides.
  11. Immediately before installation, using a lime-gypsum mixture, align the bottom of the window opening.
  12. The window sill is fixed with wedges. After installation thermal insulation material finally fix it.
  13. Installation of ebbs is carried out from the outside of the opening- for the entire width of the frame penetration into the base.
  14. The gaps between the casing of the base and the box, as well as the upper and sides of the window, are closed with a casing. It is advisable to use the same type of wood from which the house is built as platbands.
  15. All parts of the casing are interconnected. To do this, use spikes, nails or adhesive solution.
  16. Preliminary marking of placement fasteners (the step is 10-12 cm).
  17. So that in the process of fastening the platbands they do not move, the design can be put on glue.
  18. The final step is to fix the platbands with nails or self-tapping screws., and closing the gaps between the base and the platbands with sealing material.

  1. For the manufacture of casing, wood with a moisture content of at least 10% is used., otherwise cracks form inside the structure over time.
  2. In the manufacture of pigtails is strictly prohibited use metal fasteners.
  3. Building foam cannot be used as a sealing material when assembling the casing. In this case, the wood is bonded, which prevents its natural shrinkage.
  4. In the process of installing windows, it is important to properly drill holes for them. Optimal Distance from the window sill to the floor is 85-90 cm.
  5. Experts do not recommend installing windows without installing a pigtail, even if the house was built many years ago and the log house is completely dry. This is due to the fact that throughout the entire life of the tree has a tendency to shrink.
  6. For greater efficiency and heat retention, wooden windows should be installed closer to outside window hole.
  7. As a material for the window sill, it is necessary to choose hardwoods. The window sill made of glued wood has the longest service life, the window sill made of solid wood has the shortest service life (as a rule, the product is warped).
  8. The corners of the window opening should be 90 degrees, and the diagonals should not differ by more than 10 mm. If the hole in the base is larger than the allowable value, more sealing material will be required. If you do not ensure the evenness of the corners, warping of the box is possible.
  9. It is important to correctly calculate the depth of the window in the opening so that the dew point isoline, equal to 10 degrees, passes in its inner part. Then the formation of condensate on inside there will be no window.

Installing windows in a wooden house is easier than in brick or concrete buildings. This operation has a number of features, which we will discuss below.

Preparatory procedures are half the battle. a lot will depend on them.

Dismantling of old frames

Before inserting windows in a wooden house, it is necessary to dismantle the old ones. If your house is new and there are no double-glazed windows at all, you can skip this item. Most offices for the dismantling of old windows will take 50% of the cost of new ones. Therefore, to carry out this procedure independently is beneficial from an economic point of view. In addition, it does not require special skills.

Tip: old frames can be used for greenhouses or outbuildings.

Armed with a puller, a screwdriver and other tools, you will need to dismantle. We start with the sashes: open them, remove them from the hinges and pull them out. Next, remove the frames, window sill and other elements.

Creating a simple casing

If we are talking about an old building and such elements already exist, you can skip this paragraph. Before you install a window in a wooden house, you need to create a "casing". An okosyachka is a structure along the opening, which saves the frames from all kinds of damage. The beam (including the "round timber") begins to deform over time - this process is called shrinkage. So that it does not affect the brand new double-glazed window, and install this design.

It is created as follows:

  • We cut out protrusions from a medium-sized timber (3 pieces - for each side of the opening). They will be needed to create carriages (side elements). The end bars should be set to a depth of 5 cm.
  • At the ends of each of the elements we create grooves - for reliable fixation. So that they do not creak, we cover the structure with rolled tow. Such a measure will also increase the thermal insulation of the window.
  • We get a U - shaped design. It must be mounted in the opening using large nails (200 mm) or special self-tapping screws.

There are other options for creating a pigtail, but this one is the simplest.

We prepare tools and materials

We will need the following:

  • Powerful drill and screwdriver.
  • Level (preferably laser).
  • Chisel.
  • Roulette.
  • Gloves.
  • Mounting foam (or similar material).
  • Pliers.
  • Spacer bars (you can do it yourself).
  • anchor plates.
  • Hexagon (it will be needed for finishing fittings).
  • Anchor screws.

Main front of work

From preliminary procedures we pass to the final stages.

Measurements and design

Self-installation of PVC windows in a wooden house begins with measurements. You will need to do the following:

  • Armed with a tape measure, measure all sides to the nearest millimeter.
  • We draw on paper a project of the future window with the preservation of all proportions.
  • We mark the places of separation, vents and other components that you want to see in your double-glazed window.
  • Having on hand ready plan, you can contact the company for the manufacture of windows.

Starting stage - window sill

Installation must begin with the window sill, as it is the basis of the entire structure. Install it like this:

  • Two grooves with a depth of no more than 10 cm are cut from the side in the box. This will allow you to securely fix the window sill.
  • We apply it and, if necessary, level it with wooden plates prepared earlier.

Tip: if you mount the window sill at the end, a gap will form, which will need to be repaired regularly. Installing it under the frame increases the efficiency of the structure.

  • Having achieved an even location, we fix the window sill with the help of self-tapping screws. Under the hat you need to put a rubber gasket - this will prevent possible cracking of the plastic.
  • We drill holes where the window sill will cover the frame. They need to be done at low speeds so as not to damage the plastic. If you use a powerful drill, during drilling, it may begin to melt, so it is better to arm yourself with a screwdriver.
  • Adjust the level. The window sill must be strictly horizontal!

Some manufacturers offer double-glazed windows without window sills (they are purchased separately and installed at the end). We advise you to purchase all the items at once from one seller - it's more reliable.

Preparing the ground for future work

Do not rush to remove the factory film - it will protect the structure from damage. We work in the following sequence:

  1. We take out the frames and install the handle. To do this, put it in a horizontal position, fix it with bolts and lower it down.
  2. We mark on the side racks the places for drilling the holes necessary for fixing the frames. Drill - 6 mm, respectively, self-tapping screw - 5 mm. On each side rack you need to make 2 holes (total - 4). They should be located at a distance of 30-40 cm from the lower and upper ends of the beam.
  3. In order for the self-tapping screw to securely rest on the frame, it is necessary to drown it. To do this, use a 10 mm drill to make holes to the iron frame. The cap should freely enter the cavity of the beam.

We mount a PVC window

The turn of the most crucial stage has come - the installation of frames. We put the finished structure in the opening. We adjust on both sides of the frame and control them with a tape measure and a level. The distance from the sash to the pigtail on both sides should be the same (within 1 cm). You also need to control the verticality of the installation. This can be done with a plumb line.

Having achieved an even position, we put a spacer bar between the box and the frame. It will act as a stop during installation - without it, when screwing in the screws, the frame can go to the side. Having installed the bars, once again carefully check the evenness of the location along the slope. After making sure that the window is perfectly horizontal (vertical), we fix the window with self-tapping screws. They should be located between the window and the box.

This method of installing the box is highly reliable and mobile - if the wood is deformed, the frame will not warp. This is achieved due to the fact that the self-tapping screws are able to go in the direction of skew.

  • We insert the adjusting plates between the drain holes (they are needed to drain condensate - without them, the double-glazed window will inevitably fog up).
  • We insert a double-glazed window into the opening. It should not stand tightly - this is due to seasonal deformations of wood and other materials.

Important! If you find that there is no standard gap (5-7 mm), contact the manufacturer, as this is an obvious defect.

  • We evenly install the double-glazed window and fix it with the help of glazing beads (they should be included in the kit) with profile spikes. You need to tap on them until a characteristic click appears, signaling the correct insertion.
  • All existing gaps are filled with mounting foam. After 2-3 hours, cut off the excess with a knife.

This completes the installation of windows in a wooden house with your own hands.

A few words about cash

First of all, it is needed to increase the insulating properties and hide flaws. It closes the foamed cracks, which completely prevents the possibility of cold air entering inside. There is a second function - aesthetic. Cashing windows in a wooden house favorably frames the opening, giving it an attractive appearance.

It can be performed from various materials most often made of plastic. This prefabricated structures, which only need to be fixed with self-tapping screws along the perimeter of the window. However, carved cashing is sometimes performed for wooden houses. It can be made to order or independently, if a person has carpentry skills. After installation, the cashing is covered with an antiseptic and wood varnish - this will prolong its life.
