The technology of installing plastic windows in a wooden house. Features of installing windows in stone, frame and wooden houses Installation of plastic windows in wooden openings

Greetings dear readers!

I decided to replace the old windows in a wooden house on my own. This is not at all easy, so before that I reviewed a bunch of sites and forums, talked with friends who performed the installation. And he singled out for himself the basic rules in the installation.

First you need to take measurements of windows in order to know the exact dimensions and order the window correctly.

Next, you need to dismantle the old windows. Then he prepares the installation site of the window, for this you need to remove the dust and debris accumulated during dismantling. Next, we install the window sill and prepare the plastic window for installation. Then install the window itself.

At first it seems very simple, but there are little nuances, given that you can easily do it. I want to tell you more about the installation later in this article.

Do-it-yourself installation of plastic windows in a wooden house. Installation technology. Instruction, photo

Installation plastic windows with your own hands in a prepared pigtail wooden house, as well as other construction and installation works, is carried out with the help of a building level and a plumb line.

It is very important that the plastic windows in the house are strictly level, otherwise an open, for example, window sash will close itself or, on the contrary, open under its own weight. Thus, the technology of installing plastic windows in the pigtail of a wooden house includes setting it in terms of level and plumb before fixing the window.

Here is our, developed by our own experience, instructions for installing plastic windows in a log house.

First, I would like to note one point that you will need to remember when buying plastic windows: When you buy windows, it would be good to immediately buy mounting brackets for them, ideally 6 pieces per window.

These are iron plates (see photo) which, with the help of little effort, are fixed in special technical slides on the sides of the window frame. Thus, the frame is attached to the pigtail using self-tapping screws through these mounting fasteners.

During installation, many plastic window installers fix the window by drilling through the frame, but this is a violation of technology, and the tightness of special air chambers in the plastic window profile is thus violated, so this is not our method.

Plastic windows in a wooden house are generally a very capricious thing, but if observed right technology installation, then such windows in your house will last a long time without upsetting their owners with all sorts of distortions and other problems.

In order to prevent the installation of windows with your own hands from becoming a torment, we advise you to remove the window sashes from the window frame. To remove them, you need to pull the pins out of the loops. Without window sashes, the frame weighs a little, and it will be much more convenient to tilt it, which will greatly facilitate the installation of windows.

The instructions for installing plastic windows in a prepared pigtail of a wooden house are as follows:

Align the window. We put the window on the lower part of the opening on chips about 2 cm thick and adjust it horizontally in level. For setting a horizontal level, the best tool, in our opinion, is a water level.

You can't deceive water, it always levels off with the horizon.

Thus, setting the window exactly at the level of the horizon, placing chips of the required thickness under the frame for this, will leave about a two-centimeter gap below for foaming mounting foam, we move on to setting the vertical level so that the window sashes do not live their own lives.

How the vertical level is set when installing a plastic, and indeed any other window, I think it’s not worth explaining in detail, everything is clearly visible in the photo.

After we put the window on the level, we fasten it to the pigtail with self-tapping screws through the above-mentioned mounting fasteners.

There is one technological point here - do not hit the crest of the log on which the pigtail sits with a self-tapping screw.

It is better to screw in the self-tapping screw a little obliquely than to deprive the design of the pigtail of independence from the log house in terms of the free movement of the gun carriages along the ridges of the logs.

The next step in our instructions for installing plastic windows in a wooden house is to fix the window sashes. It is necessary to hang the sashes on the window before foaming, but if you foam the frame without sashes, the mounting foam can slightly bend the frame, and the sashes will close / open poorly.

Thus, if the technology is correctly followed and the installation of the pigtail and the plastic window is evenly done, your window should stand in such a way that distances of about 2 cm for mounting foam remain on all sides from the frame to the pigtail.

And over top the pigtails will have a gap of 5-10 cm to the log to shrink the log house, so that when it dries completely, the upper logs do not press on the windows.

Window foaming. Control check - On the already fixed, but not yet foamed window, with the shutters inserted, open the window and look.

If the half-open sash of a plastic window does not try to open further or, on the contrary, close, then our window is installed correctly and you can foam the frame with mounting foam.

Here we have such a technology for installing plastic windows with our own hands. We hope you find it useful in the construction of your wooden house! Happy building!

How to install plastic windows in a wooden house with your own hands

In our wooden house, we decided to replace the old wooden windows with modern plastic ones. This article discusses in detail the installation of double-glazed windows with your own hands in a wooden house. The article is based on personal experience. Why is it profitable to install windows yourself:

When installing double-glazed windows in a wooden house by a supplier or manufacturer, the cost of a window along with installation will cost 40-50% more than its original cost.

As a rule, about 95% of companies that install windows do not guarantee the quality of installation in a wooden house. Therefore, when self installation in a wooden house you do not lose plastic windows warranty period operation, but only save yourself for the good.

The installation of windows is shown on the example of self-installation of double-glazed windows, without the help of strangers, which takes an average of two and a half hours (for one window). Further, the process of inserting a plastic window into the window opening of a wooden house is described step by step.

Removing old windows

Self-installation of double-glazed windows in a wooden house is carried out on a solid foundation (frame). Since in our example the window boxes were installed quite recently (about 5 years ago) and were without damage (cracks, chips, putrefactive formations and wormholes), we decided to use them instead of the frame for installing new windows.

Old window frames that are in good condition and have sufficient strength can be reused, for example, to install a greenhouse.

Therefore, in order not to damage the frame tree, their dismantling must be carried out carefully, and before that it does not hurt to remove the glass from them. In our case, we did not pull out the glass from the frame, since the strong frames did not warp when they were removed and were dismantled quite easily.

Preparation of a place for the installation of double-glazed windows

With a dry and clean cloth (or soft brush), you need to wipe the window frame, remove the waste and debris accumulated after dismantling.

The PVC window sill is mounted first, as it is the base of the double-glazed window when it is installed. In this regard, the window sill should be installed as evenly as possible (ideally horizontally). We check the exact horizontal position of the window sill with a level both in the longitudinal and transverse positions.

To make the window sill stand firmly, we make cuts up to a depth of 8 mm on the sides of the window frame. To adjust the evenness of the window sill, we use special plates made of plastic or fiberboard, or thin wooden planks treated in advance with an antiseptic. After final installation window sill we measure the evenness of the window sill with a building level.

We fasten the window sill on self-tapping screws to the bottom of the window frame, while indenting from the outer end of the window sill by 2 cm. PVC window sill has cavities). After the window is fully installed, the window sill attachment points will not be visible, as they will be hidden from view.

Preparing a plastic window for installation

At the very beginning, even before you start installing the window, you need to install the handle. It is not yet necessary to remove the entire protective film from the window surface, as it protects the window from possible mechanical damage.

Note!

The protective film can only be removed where the handles need to be installed. Handles of the handle at their installation should be in horizontal position.

This position means that the window opens on its side, while if the handle is turned down, the window will be locked in the closed state, if the handle is turned up, the window will open in the cranking mode.

We fix the handle to the window with two bolts, move the handle handle down. On the side pillars of the window (at the ends) we make markings for making holes on which the window will be fixed to the block.

Next, we drill with an electric drill according to this marking, two through holes (lower and upper) in the right rack of the double-glazed window and in the bottom rack (in total - 4 holes). The distance between the lower and upper parts of the double-glazed window to the hole should be from 25 to 35 cm. The diameter of the drill for this work should be 6 mm, while the diameter of the self-tapping screw is 5 mm.

In order for the screw head to firmly rest against the window frame, we drill holes on the side posts from the inside for fastening with a drill with a large diameter - 10 mm, up to the metal frame itself. The hole should be such that the head of the self-tapping screw freely passes into the cavity of the window pillar.

window installation

We install the assembled window in the window opening. The center is controlled by measurements taken with a tape measure starting from the edge of the window and ending with the surface of the window frame on both sides, the distance should be the same (about 1 cm each).

We install the window on the surface of the previously installed window sill. Since we have already checked the window sill for evenness using the building level, there is no need to control the window itself for horizontality.

For a window parallel to the wall of the house, install between the wall and the siding to stop building level. If the house was sheathed by another finishing material for example, a clapboard that fits snugly against the wall and does not allow you to place a level, then you need to use a plumb line for control.

We install a spacer bar 1 cm wide between the window frame and the window. It is necessary that this bar enters between the window frame and the window tightly enough. This bar is needed as a stop at the moment when the window is fixed in the window opening using self-tapping screws.

If this is not done, then the window, when it is fixed, may go to the side (it will simply be taken away) and the mechanism for opening and closing the window will not function well, or the window sash will not open at all.

When the installation of the stop bars is completed, and the window is leveled or aligned parallel to the wall of the house, then we fix the double-glazed window on the self-tapping screws. We fix the window to the window frame from below and above its side posts, so that the self-tapping screw is in free space between the box and the window.

Such fastening is not only reliable, but also provides a floating effect. If there will be seasonal shifts in the structure of the house, distorting window openings, then windows that do not have a rigid binding to the frame are almost not subject to distortion, due to the fact that the self-tapping screw can arbitrarily move towards the window frame skew.

Installation of double-glazed windows in a wooden house

First, we install adjusting plates between the drain holes. This is necessary so that the double-glazed windows do not close the holes through which condensate is drained from the window.

Carefully install a double-glazed window in the window opening. We make sure that it does not fit tightly between the racks of the window, since if seasonal changes occur and, accordingly, distortions of the window frame, the glass may burst.

Note!

If your double-glazed window entry is tight, and there is no gap between the window pillars and the double-glazed window (at least 5 mm), then you should contact the company that made windows for you for your order for an explanation, so that the company's employees eliminate this shortcoming. It is necessary to check the gaps between the frame and the double-glazed window even before removing the old window.

We install the double-glazed window evenly and fix it with plastic glazing beads, which have profile spikes that are inserted into the grooves of the window frame with with the help of a lung tapping on the glazing beads, in which the spike passes into the groove and a click is heard. A click indicates that the bead is securely fastened.

After the window is installed, we fill the void between the window frame and the window with mounting foam, both from the inside and outside of the house. Excess hardened mounting foam is cut off with a sharp knife.

After that, you can start finishing with platbands, fittings and drainage.

How to install plastic windows in a wooden house

The relevance of the question: "How to install plastic windows in a wooden house" (and not only plastic ones), lies in the fact that wooden houses are very unstable. Moreover, unlike a stone or reinforced concrete house, this instability manifests itself throughout the entire service life of a wooden house.

If these factors are not taken into account when installing plastic windows or doors in a wooden house, very unpleasant (to put it mildly) problems can arise!

What is the peculiarity of a wooden house? And the fact that the tree tends to "shrink", especially in the first years after construction. Those who claim that the log house shrinks a year after its installation are mistaken.

Yes, the most noticeable shrinkage occurs in the first year, but the process continues for at least 5 years, and in some climatic zones - for a lifetime! As the logs or beams dry out, the height of the wall can decrease to 1.5 cm per meter of masonry. This means that the height of the wall can “shrink” up to 6 cm.

And now imagine what will happen to a plastic window if, as always, you left a gap of 2 - 2.5 cm for foam ?! So, installing plastic windows in a wooden house is generally unrealistic? Quite the opposite!

But only if a special structure, called a pigtail or casing, is installed in the opening.

The purpose of this design is to give windows (and not only plastic ones) complete independence from bearing walls at home, to exclude even the slightest load on the window during shrinkage or curvature of the walls:

  1. The casing prevents the logs from moving from the vertical in the window opening.
  2. Does not interfere with vertical shrinkage.
  3. Takes all the load.
  4. Strengthens the wall of the house in the opening area.

Let's take a look at this system in detail. The simplest casing option is when a vertical groove of 50x50 mm is cut at the ends of the opening logs and a bar of the same size is inserted into it.

But this method of braiding is ONLY suitable for wooden windows. Therefore, we will not dwell on it. A more reliable option for casing is when a comb is made at the ends of the logs, and a window carriage with a groove is put on it.

Now the logs during shrinkage (due to the ridge) will slide inside the groove without deviating from the vertical and without pressing down the window.

It happens that the groove is made in logs, and the spike on the gun carriage, the main meaning, I think is clear.

Window carriages are vertical bars 150x100 mm, at the ends of which 50x50 cutouts are made for inserting horizontal lintels - boards 150x50 mm with spikes at the ends.

The assembled casing is made smaller than the window opening by 7-8 cm in height. This gap is left in the calculation for the shrinkage of the wall. When assembling the pigtails in the opening, we cover the ridges with rolled tow and fill the gun carriages on it. This will save us from squeaks during shrinkage and insulate the opening.

Note!

Further, the procedure is as follows - we lay the lower jumper, stuff the gun carriages on the comb with tow, we wind up into the upper gap and lower the upper jumper into the grooves. We fasten the entire structure with self-tapping screws, trying not to capture the ridge, otherwise the whole point of installing the casing will be lost. In the gap between the pigtail and the logs, we also hammer in the tow.

And now you can insert plastic windows into a wooden house without fear for the consequences. We make installation in compliance with all technology: steam - noise - moisture protection. The gap between the casing and the frame is filled with thin boards wrapped in tow.

As the house shrinks, they have to be knocked out and replaced with others. To do this, the upper casing (attached only to the casing) is carefully removed and, after replacing the filling, is put in place.

At seminars, I was often asked the question, why does a window fitter need to know the technology of building a wooden house. And then, so that you can determine whether it is possible to install a window in this opening.

And, if necessary, equip it with a classic casing. Of course for a fee. There have been cases like this in my experience.

Now like this important point. You insert a plastic window into a wooden house where there are wooden windows. They removed the platbands for accurate measurement, but there is no casing. That is, the box of the old window plays the role of a pigtail.

This is where the choice has to be made (by the owner, but with your help): to remake the window opening for casing or to significantly reduce the size of the future window. After all, on each side you need to add the thickness of the casing + window frame + gap for foam. And what will be left there?

And in conclusion, I want to warn:

Helpful advice!

In no case do not agree to the installation of windows without casing in the opening. Even if the owner proves that the house is 300 years old and "all the shrinkage has already settled down." The tree "breathes" all its life with all the consequences, as they say.

Well, in the most extreme case, you can give in to the client, under his responsibility. But do not forget to put a dash in the contract in the column "Guarantee" !!!

All the same, the installation of plastic windows in a wooden house requires very serious attention.

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 construction 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 design features. Since they affect the technology of window installation, any developer should be aware of them.

From our article you will learn:

  • How to prepare for the installation of a window structure;
  • 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 is the protection of mounting joints;
  • 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 wide range 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.

Installation of wooden windows in frame house with your own hands.

We install wooden windows with our own hands

Developers believe that PVC installation and a wooden window there is a big difference, but experts do not agree with this.

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.

AT in general terms installation consists of the following steps:

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

Anatoly Gavrysh

I would like to dispel the illusions about the ease of installation of both plastic and. To do it yourself, you definitely need certain skills and special equipment, since correct installation is of decisive importance in how well and how long the 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 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 a change in the design 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 developers are starting to cut an opening in timber walls only a year or even two after the construction of the house. During this time, it is possible to track all deformations, taking into account the characteristics of the material and the climatic 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 plant origin(tow). Of course, the tape and coating materials needed to protect assembly seams, should also have a high class of deformation stability.

Glued laminated timber shrinks much less than solid logs. Eventually glued laminated timber less deformed than a conventional 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 different types, concrete, aerated concrete blocks- these are standard Construction Materials. The technique in stone houses has been worked out for years. Fastening is carried out using dowels and construction screws, the use of anchor plates is also allowed.

Anton Karyavkin

In some cases, 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.

Wooden houses, baths, saunas and cottages have an important advantage - they are completely environmentally friendly, because they are made of natural material. A wooden frame is “alive”, it “breathes”, it shrinks and grows old, that is, it lives its own life. A house made of natural wood circulates air, purifies it and gives it healing properties, thanks to phytoncides and resinous substances of natural pine wood. These same features of buildings made of lightly processed wood create some difficulties. For example, when it is required to install windows in a log house and doorways, as well as when finishing sagging walls, but subject to the installation technology, all these problems can be solved.

Which windows are suitable for wooden walls

The walls of solid wood houses tend to be in some movement. This is influenced by the time of year, seasonal changes, air humidity and environment- the frame swells or shrinks, sitting down. Some conventional window and door installation standards are acceptable for log cabins, so a different frame recess design, known as casing, is needed here. It makes it possible to minimize the movement of the wooden walls of houses, baths and other residential buildings made of logs.

However, not everything is so complicated, since the main shrinkage occurs during the first 3 years - under its own weight, the space between the logs is compacted and the wood naturally dries. Sometimes during this time the log cabin sags by 10-15 cm, respectively, the window and door opening decreases. Therefore, it is natural that wooden windows in a log house are more suitable for a new structure made of natural wood, and plastic windows for older houses, then they will be less subject to excessive pressure and deformation.

If the construction of a house has been going on for more than one year, stage by stage, then even unprepared "live" wood will sit down during this time, and installing windows in a wooden log house will not be a problem. In extreme cases, you can install temporary frames with a film that prevent the penetration of precipitation into the window opening. And after a while, window frames with double-glazed windows can be placed in a wooden log house to protect against adverse weather factors. These can be frames made of specially prepared dry wood, or made of plastic that is familiar to city dwellers.

Laminated under natural wood, modern plastic windows will organically fit into the design of the log house, increasing the thermal insulation of the house. The experience of installers from Finland shows that a plastic window in a log house or double wooden frames can be inserted into a pigtail without any problems, while it is possible to combine different materials for window frames.

What is important to know about installation technology

Today they make prestigious two-storey houses different type. They are built in an eco-style according to the traditions of their ancestors and according to the projects of modern architects and designers. Increasingly, they began to offer wooden houses and saunas similar to Finnish ones, also in fashion stylization country houses under the Russian tower. No less interesting are the large estates in scandinavian style- made of wood and glass. It doesn’t matter if the building is pompous or small cottage do it yourself from wood - the technology for installing wooden windows in a log house is approximately the same.

Of course, damp wood is not very suitable for building the walls of a wooden house. The Finns use only dried and specially prepared wood for export houses, and also develop special technology for houses that are quickly assembled. According to the technology, window frames are not placed in a log house for at least six months after the assembly of prepared structures, and even later in "live" wood. But even in this case, some shrinkage is taken into account - do not leave the building without windows.

The exposure time is required for the shrinkage of the log house and the final formation of wooden walls, and in about a year the log house will acquire shrinkage close to the maximum parameters. However, it is not possible to accurately specifications shrinkage (as a percentage or in millimeters), since everything depends on the type of wood and its degree of moisture.

Today, several options for installing windows in a log house have been worked out:

1. The most reliable method is the installation of a casing (casing) where a window is inserted. The casing is a one-piece rectangular structure made of solid wood up to 40 mm thick, in which the lower bar forms a window sill, and platbands are attached to the ends. Long time they were made from solid wood, giving the required shape, where the grooves for the window frame were formed. Today, the casing is being made much more technologically advanced and looks more aesthetically pleasing, and a glue beam is used for its manufacture. The finished casing design is quite expensive, so they often use a more affordable technology for installing a window in a log house, that is, fastening to cranial bars.

2. There is another option - the window frame is attached directly to the beam with special fastening strips. Simple Methods are used, most often, in log cabins of baths and saunas, and in residential buildings - more complex and reliable. Using the building level, the window frame is set in compliance with the distances and foamed with sealant. However, the installation method with sealing in the new walls of houses is not used. Foam is recommended to be used to seal the lower part of the frame and window sill - this plane is less susceptible to deformation when a wooden window shrinks in a log house.

3. Often, special (cranial) strips are used, inserted into the grooves, which move freely at the ends of the window opening. This counteracts jamming during shrinkage without the formation of gaps. The cranial planks are able to slide in the grooves due to the design, so the window will not experience pressure when it shrinks. The difference of the method is in attaching the casing to cranial bar, and not directly into the opening.

Tip: Remember that even after the initial shrinkage of the log house, the compaction of wooden walls will continue for some time. With significant precipitation and in a climate with a high level of air humidity, the base of the log house will continue to absorb water, increasing the log house in volume. In hot and dry summers, the tree gives off moisture, giving a significant shrinkage. That is, natural changes in the size of a log house, for example, from pine, will be noticeable up to 5 cm, but this figure also varies depending on the time of the log house. Installing windows using special technology reduces the likelihood of warping, displacement of the base and jamming of the sashes and reducing heat loss.

Basic conditions for the use of casing

1. Log house casing makes it possible to prepare the installation of the window in a formed box, which minimizes the pressure of the log house on the window frame through the natural drying process of the wood.

2. Properly made log house casing prevents distortions in the form of shrinkage consequences.

3. There should be a small gap above the frame, approximately 50 mm, and it is insulated along with side gaps.

4. A simplified casing can be made of boards of a smaller thickness of about 20 mm, where the forming slopes will be attached, and the bottom board forms a window sill.

5. The casing is fixed with self-tapping screws on the cranial beam, and the gap is insulated under the platbands.

6. Casing from the outside looks quite compact and neat, and inside you can put another frame.

7. Proper use of casing installation technology helps to counteract window depressurization.

8. Fastening of external architraves allows the use of synthetic seals, including rubber, to prevent moisture from penetrating into the window space.

9. In case of difficulties and questions - how to insert windows into a log house, it is recommended to contact specialists.

The main problems when installing doors and windows in a log house

1. According to the experience of installing houses made of natural wood, even a structure made of specially prepared and well-dried material will shrink up to 5 cm in the 1st year. In steady rainy weather, the house will swell again. "Live" or non-dried wood with a high percentage of moisture gives a much greater amplitude per year.

2. Installation of windows or doors in a wooden frame is a technologically simple process, and specialists have no problems. However, difficulties and problems with an unprofessional approach arise much later, when the windows in the bathhouse or in the house begin to warp due to pressure during the natural drying of the wood. That is, it is much worse when problems emerge during the operation of the building.

3. high humidity air can lead to the fact that window sashes or vents do not open due to swelling of the wood with increased pressure from the shrinking logs. Sometimes it is enough to trim the adjacent planes of the sashes a little, and it is worse if the window cannot be opened for the entire period of operation. It is for this that a small clearance in the casing or the correct sliding structure is important - in order to avoid such troubles.

Tip: It is important to use dry and high-quality timber, preferably from conifers wood. Before cutting window openings, it is important to strengthen the boards on its sides so that they do not part.

Instructions for processing a window opening

To perform the work, you will need a chainsaw, nails, studs, timber, edged board, square, plumb and polyurethane foam.

1. On the wall of the log house, the contours of the window (door) opening are marked using 4 strips. It is important to correctly mark the lower part of the window - about 80 cm from the floor.

2. Boards are selected a little more than the height of the opening to secure the studs with washers.

3. We make holes in the uncut crowns at the corners of the planned opening, similarly in the fixing boards.

4. We mark the vertical with a level and attach boards along it, which we connect to the logs with the help of studs and tighten the boards.

5. We put metal washers under the nuts to prevent the nuts from cutting into the boards, we fix the boards on both sides of the marking.

7. We proceed to the processing of sawn logs and fasten the edges together with jumpers.

8. We form a window block from lintels and jambs in pairs, and outside we form grooves for the size of the spikes.

9. We begin to form the window block with the installation of jambs, with nails we connect the jumpers with the sticking of logs.

10. To check right angles, use a square, which can be formed before the final fixing of the block.

Tip: To dispel doubts, it is advisable to watch a video about installing a pigtail, and only after that proceed to the installation.

Step by step installation of windows

Today, there are several ways to install window frames in a log house, but we will look at the simplest example.

To begin with, you need to visually imagine in a section what a window in a log house looks like - the scheme for installing a window in a log house is shown in the figure below.

These are a casing with grooves, a shrinkage gap with a sealant, an outer and inner casing, a spike with a sealant, a window with a tide, a lower interventional sealant.

The pigtail is made after the formation of the opening:

  • prepare a beam 150x40 under the top of the window opening, it should be the width of the opening, cut out 2 rectangular cutouts from both ends for a pre-formed comb;
  • install the board on top of the carriage bar, securing it with self-tapping screws;
  • we make an opening of 3-5 cm more than the height of the inserted window, for filling with a sealant or foaming from below;
  • the gap between the log and the salary board in the window opening should be about 5 cm (for shrinkage), which is filled with insulation;
  • when the window is inserted and fixed, a platband is attached to the pigtail so that the structure has an aesthetic appearance;
  • do not forget to check before installing the platbands and the final installation both vertical lines of the window frame along the plumb line and horizontal lines along the level, since this will not be possible to correct further;
  • it is necessary to impregnate all wooden surfaces with an antiseptic to counteract the destruction of wood.

The process of installing plastic windows in a log house

The step-by-step process of installing PVC windows looks about the same as in the example with natural wood:

  • we form a window opening;
  • install a pigtail;
  • we are completing the installation of a plastic window in a pigtail according to the technology.

The optimal distance of the window sill from the floor is 80-90 cm, and if the interior design plans to use a window sill in the form of a tabletop, for example, in the kitchen or in a teenager's room, then it is better to think over its design and installation in advance.

Tip: Remember that wooden frames partial shrinkage is also characteristic, and PVC windows have a rigid and stable base - they cannot be placed in a fresh log house, and it is imperative to use a pigtail. It will make it possible to maintain sufficient autonomy of the double-glazed window from the log house, so installation on foam and without a joint is unacceptable in this case!

Two types of pigtails:

1. Simple design- a groove 50x50 mm for a bar is formed at the end of the opening (not suitable for installing a PVC window).

2. A more reliable option is when a ridge is formed in the end logs on window openings, on which a frame with a groove, otherwise called a "carriage", is subsequently placed, and here, during shrinkage, movement along the guides without deformation will be ensured. This is a construction of a bar 100x150 mm, which exceeds the size of the window by 5-6 cm, in the center of which a groove of 50x50 mm is selected, the carriage is attached to the ridge.

Next, we assemble a pigtail from a 150x40 board, as described above, respectively, cut grooves in it that are put on a comb - this is the upper part of the opening where we put the PVC window. Be sure to cover the slats with tow (in rolls) and fasten the gun carriages, and fasten the upper bar of the pigtails with screws to the gun carriage.

After the right angles, vertical and horizontal lines in the openings are verified, the pigtail is framed, they proceed to the installation of plastic windows. Monitor the quality of fastening and tightness so as not to disturb the thermal insulation of windows in a log house. Do all the steps according to the instructions attached to the PVC windows. When buying plastic windows, pay attention to the mounts that are mounted at the end. The frame is leveled and mounted with fasteners to the pigtail, do not forget about the place for mounting foam under the window sill. It remains to hang the sashes and cash out.

Tip: Pay attention to how the window is screwed to the board - in no case to the ridge, otherwise the meaning of the movable fastening of the window to counteract shrinkage is lost.

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 a we are talking about the 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.
  • With a ready-made plan in hand, you can contact a window manufacturing company.

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 is 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.

Installing plastic windows in wooden houses increases the thermal insulation of the entire building, reduces several times the cost of heating the room. Many doubt the possibility of performing this operation and think that some auxiliary means or materials will be required to install the structure. In some houses, it is enough to remove the old one and replace it with new PVC, while other buildings require more complex steps. To understand this, it is necessary to study the issue more carefully, to learn the recommendations of experts.

Is it possible to change old window structures to plastic ones in a wooden building?

Depending on the type of wooden house, its age, the installation of plastic windows in it can be carried out according to a simplified scheme or in a more complex and time-consuming way. But the replacement of old wooden windows with similar plastic ones is available to everyone.

Frame-panel type

Due to the absence of shrinkage in such structures, replacing wooden windows with plastic frames is easy. All manipulations are performed according to the same instructions as for stone or panel structures..

Log cabin

Installation of metal-plastic and plastic windows is permissible in such structures not immediately after their construction. Since logs and beams must take their place in the building structure, it is necessary to wait from 2 to 3-4 years (depending on the characteristics of the materials used).

Attention

Installation of PVC window frames in log houses before waiting for their shrinkage, it is dangerous to damage the frames and deform them.

Installation rules:
  • Shrinkage time should be 2 years or more. The timing is affected by the characteristics of the wood, the level of drying, the method of harvesting.
  • During the period of shrinkage of the structure, wooden windows can be installed, which will then be replaced with plastic ones.
  • It is required to organize an expansion gap of no more than 12% of the frame height, which will allow installing PVC windows immediately after the construction of the house is completed.
  • Boards of thin section with tow winding on them should be used to seal the compensation gap, which will protect the frame structure from damage during the shrinkage period. As the structure subsides, such boards can be removed or left until the tow is compacted without damaging the structure.
  • Installation of casing - a special box made of durable thick bars. It is used as a frame for a window opening and fixing a window on it. In the house, this element also performs a protective function, since it prevents pressure on the wall window during shrinkage.
Casing can be designed and installed at any period of building construction and its shrinkage. But without it, installing PVC windows is not recommended at all.

Features of work performance

When replacing old windows with new ones made of plastic, follow the procedure:
  1. When replacing a window with casing, measurements must be performed after removing the latter from the window opening, otherwise the measurements taken will give significant deviations.
  2. If the window is replaced in place of the old one while maintaining its frame, then it is necessary to take dimensions from this element after removing the window frame.
  3. The replacement of the pigtail (casing) is carried out first, and it is better to enlist the help of the masters, since this element sets the operating conditions for PVC windows in the future.
  4. When installing new windows, it is required to leave 1–2 cm for the installation gap on all sides of the opening. It is then sealed with mounting foam, but without it, installing the window correctly and without effort will not work.
  5. When installing new double-glazed windows, all operations are performed in the same way as for panel or stone buildings - double-glazed windows are removed from the frames, fixed frame structure on the box with anchors with corresponding plates, which are attached to the frame and the wall with two self-tapping screws.
  6. Sealing tape is used to isolate the mounting joints between the frame and the walls.
  7. At the last step, double-glazed windows are inserted into fixed PVC frames. It is necessary to hammer them around the perimeter with plastic glazing beads with rubber insulation. This will increase the energy efficiency of the structures.
  8. The adjustment is carried out after the installation of the sashes and all double-glazed windows, when the load on the structure is set to what it should be during continuous operation.

When replacing a window frame, it will be necessary to use boards or bars with a thickness of 5 cm or more, and the organization of a sealing insulating layer. Therefore, measurements must be performed accurately, with the necessary allowances for the layers of auxiliary materials.

Installation options

Replacing old windows with new ones PVC structures in buildings made of wood is produced in several ways:
  • installation of a new casing when installing a plastic bag;
  • installation on an existing pigtail;
  • replacement with preservation of window parameters;
  • expansion of the opening, installation of the appropriate filling in it.
Regardless of the method, checking the status of the pigtail is required., its replacement if any flaws or malfunctions are found. This operation guarantees the reliability and durability of the new PVC double-glazed window.

With original hole size

In the case of such a replacement method, several operations must be performed:
  1. Dismantling of the wooden structure.
  2. Check for the integrity, strength of the casing, the presence of additional fasteners on it that need to be removed.
  3. If the pigtail has chips, damage, signs of decay development and other significant defects, it must be removed and replaced with a new design.
  4. Measures are taken for the casing (in case of its replacement) and / or a plastic bag.
  5. Glass preparation. Installing a pigtail or cleaning an old one, installing a window frame.
  6. Fixing the window frame in the casing, then installing the sash on it.
  7. Placement in the frame of double-glazed windows, fixing all additional elements.
  8. Adjustment, customization of the structure.

The necessary waterproofing in the pigtail with the selected quarter is impossible, and for the installation of plastic double-glazed windows this is a prerequisite.

With a change in the size of the opening

In log houses always window openings made small. The owners of such buildings are always trying to make the rooms more sunny, more comfortable for living. To do this, they change windows, expand the window opening. Replacement work is carried out in the following order:
  1. Retrieved old design with a pigtail.
  2. A preliminary markup is made with a building level.
  3. With a chainsaw or ordinary carpentry tool, a wider and / or higher opening is cut.
  4. The size of the new casing is calculated.
  5. A pigtail is being constructed, placed in the opening.
  6. The size of the new window is calculated, and then the settings are the same as in the case of saving the size of the window opening.
When calculating the format of a new window frame, take into account:
  • thickness of boards, type of casing;
  • the presence of a gap for the seal;
  • 1-2 cm for organizing a technical opening;
  • thickness of the installed window sill;
  • dimensions for the expansion gap.

Attention

The marking should be carried out so that the edges of the opening intersect the logs along their central part. This requirement applies to log and log houses.

Installation subtleties

All operations for replacing old windows in a house made of logs, log houses or frame structures must be carried out according to the instructions above. Each stage from dismantling and / or changing the size of the opening to the final decorative finishes slopes, drainage, window sills and front part should have a clear sequence. If you make any inaccuracies or deviate from the recommended sequence, then various difficulties and defects may arise, which are more difficult to eliminate than to prevent.

Necessary tools and materials

When replacing old windows, you will need such a tool:
  • protective equipment: gloves, plastic glasses or with rubber seals;
  • impact drill, screwdriver or screwdriver with an appropriate nozzle;
  • mounting foam, insulating materials, including sealing tape;
  • hexagon or bolts with self-tapping screws for installing the support mechanism;
  • wooden spacer wedges under the window frame;
  • light mallet or rubber mallet;
  • plastic chisel;
  • construction level;
  • roulette.

Even with the entire set of tools, third-party help will be required, since window frames, like double-glazed windows, have significant weight.

Difficulties during installation

The main difficulty associated with the installation of plastic double-glazed windows in wooden houses is the presence of shrinkage. Because of it, the frames can be deformed if the window boxes are not properly organized. This situation cannot be corrected because damaged structures will not allow the window fittings to fully function. The casing can have this type of construction: the bars are mounted in a groove made for them in the window opening. The use of a groove and a ridge carriage ensures the sliding of the groove-ridge structure during shrinkage. This will protect the window frame from damage and stress. Creation Method wooden block in grooves without carriage only suitable for PVC bags. In wooden buildings, the installation of plastic double-glazed windows is simple. Enough to stock up the right tools and patience. Fulfillment without deviations and initiative of all the recommendations of specialists will allow you to easily, quickly, and efficiently replace old windows. This will significantly increase the house's ability to retain heat and reduce heating costs. If you decide to insulate your house, but at the same time you do not have the opportunity to put a new plastic window, then we suggest reading about that, for the winter and about effective ones.
