Installation of a wooden window: all options. How to fix a window: an overview of fasteners and a photo report on the installation performed Insert a plastic window into a wooden frame

Windows made of strong and durable plastic can be found today not only in stone, but also in wooden buildings.

However, their installation in a wooden wall differs significantly from installation in stone structures. The reason for this is the significant shrinkage of the wood during the drying period.

In raw material, it can reach 6-8% (1.2-1.6 cm per 1 meter of log height).

Drying wood turns into a powerful press, which easily deforms the window block. The sashes do not open after such an impact, and the frame is strongly warped.

It turns out that high-quality installation of plastic windows in a wooden house is not possible - you ask? No, it is quite real, but only subject to special technology. We will consider it in our article.

How to put a plastic window in a wooden wall?

In order to eliminate the pressure of the wall on the window block, the craftsmen came up with special “sleds”, which were popularly called pigtails or casings. The idea of this technology is very simple: a vertical ledge-comb is made with a chainsaw on the end part of the logs of the window opening.

A window carriage is put on it - a wooden beam with a vertical groove cut into it. There is no rigid connection with screws or nails between the opening and the carriage. As a result, due to the sliding tongue-and-groove connection, we get a frame that moves freely along with the drying wall.

Thanks to this original solution, the plastic window installed in the casing is not affected by the destructive forces of log house deformation.

The pigtail performs several important functions in a wooden wall:

does not allow the logs to move from the vertical;
does not interfere with the vertical shrinkage of the log house;
reinforces the wall in the area of the window opening.

And now let's take a closer look at how to install plastic windows in a wooden house with your own hands using a casing.

Features of installing plastic windows in wooden walls

Cutting the ridge at the ends of the window opening must be taken very responsibly by marking it with a level. Any deviation from the vertical and the inaccuracies in the tongue-and-groove joint will adversely affect the operation of the pigtail, violating its free movement along the wall.

Having made ridge cutouts, you can begin to manufacture window carriages. These are wooden planed bars with a section of 150x100 mm. At their ends, it is necessary to make cutouts 5x5 cm in size for inserting horizontal jumpers (board 150x50 mm with two spikes at the ends).

When making a casing box, keep in mind that its assembled height should be 7-8 cm less than the height of the window opening. If you make a pigtail without such a gap, then the upper rims will press on the box when the wall shrinks, deforming it.

In order to correctly insert a plastic window in a wooden house, you must adhere to the sequence of operations established by experienced craftsmen.

First you need to overlay the crests of the window opening with tow and secure it with a stapler or small nails. This is necessary to insulate the joint and eliminate squeaks. After that, the lower jumper of the pigtail is laid in the window opening. Then gun carriages (side bars of the casing) are stuffed onto the ridges. A second jumper is inserted into the upper cutout of the carriage and lowered to a horizontal position. Having assembled the box, it must be carefully fastened with self-tapping screws so that they do not go into the ridges of the log house. Otherwise, the casing will not "work" because the screws will prevent it from sliding along the wall.

All the cracks remaining in the window opening after the installation of the pigtails are tightly clogged with tow. Further, according to the standard technology, a plastic window is installed with all related operations to ensure the protection of the junction area with the casing from moisture, heat loss and noise penetration.

The gap between the pigtail and the wall of the log house is filled with thin boards wrapped in rolled tow. As the walls shrink, they are knocked out one by one. To do this, the upper casing (it is attached only to the pigtail) is removed and, having removed the unnecessary “compensation” board, put it back in place.

The finishing of a plastic window in a wooden house is no different from the decorative sheathing of a conventional frame. It is highly desirable to order not standard white plastic windows, but covered with a special film that imitates the color and texture of natural wood. They will naturally look against the background of a chopped wall. Having completed the insulation and sealing of the joints, the window block with a pigtail from the inside and outside is sheathed with a wooden casing.

So far, we have talked about the installation of plastic window blocks in new log cabins.. But is such technology needed if we are talking about an old wooden house?

Experienced craftsmen say that a pigtail is necessary here. The fact is that any log house, even after 5 years of shrinkage and shrinkage, does not stop changing its dimensions. Wood is a living porous material. Therefore, when it is raining outside, the log and timber swell. During the hot summer, the reverse process takes place and even an old hundred-year-old log house loses a few centimeters from its former “wet” height.

It should be noted that the old window frame is absolutely unsuitable for the role of a pigtail, since it cannot slide along the wall surface, compensating for its shrinkage.

Therefore, the owner has two options:

install plastic windows in a wooden house, reducing the size of existing openings by the width of the casing + gap for sealant;
keep the same window area, but increase the openings for mounting the pigtails by cutting through the walls.

Concluding our review, let's say that installing a plastic window into a wooden wall is not a very complicated process. With a careful and attentive attitude to the matter, it can be done qualitatively on your own, without involving "expensive" masters from the side.

Addendum to the article

We sometimes receive additional questions that cannot always be answered within the comments. We will answer such questions further and give options for solving a specific problem.

Good afternoon!
With the installation of a plastic window in a log house, it is clear, but how is a plastic window installed in a house on a pediment, in which an opening for a window is formed from a board 80x100mm?

This installation option is easy. Just before installation, it is advisable to attach an antiseptic rail 20x20 mm along the contour of your box (it will act as a quarter, protecting the polyurethane foam sealant from solar radiation). If you have already made a quarter in the board, then you don’t have to put a rail.

We put the plastic window on the gaskets (to create a gap into which the foam will be blown). After that, carefully go through the entire circuit with sealant. You can additionally fix the window in the opening using metal mounting plates. However, one foam will hold the window securely.

I didn’t step back from the outer edge of the window block, but the house is old, the window block is level and somewhere in places a 50 mm board goes out into the street, and now it’s cold. What can be done?

The best option is to remove the window block and install it in the quarter-indented opening, as shown in the previous diagram.

A valid option is to make a thick board around the window block outside the wall so that quarters are obtained that cover the junction of the window block with the wall from blowing. Seal all leaks and gaps with foam or tow.

You can insert windows in a wooden house with your own hands today without resorting to the services of professionals. Modern metal-plastic window systems allow you to give the facade a neat, well-groomed appearance. Installing windows with energy-saving properties significantly reduces the level of energy consumption in a private house. A plastic window in a wooden house creates the necessary microclimate and comfort.

Features of a wooden house with PVC windows

Plastic windows are distinguished by their energy-saving properties due to their design. In order for this quality to be fully realized, normal ventilation conditions must be created in a wooden house, otherwise unpleasant phenomena cannot be avoided.

In a wooden house with PVC windows, it is necessary to properly equip ventilation

If we talk about a newly built wooden house, then its main feature is natural shrinkage, which takes some time. This is the main condition that should be taken into account when installing windows in wooden houses in order to avoid situations where, during shrinkage, the window structure is deformed and irrevocably fails.

Measurement

Carrying out measurements in a wooden house is different from measurements in houses made of other materials. This is due to the fact that wood is able to change its parameters depending on environmental influences. When moisture is absorbed, the wood expands.

The gap between the window frame and the opening should have a minimum size, but sufficient to take into account the possible expansion of the opening when the wood swells. Otherwise, window skew is inevitable.

The gap between the frame and the opening is left taking into account the possible swelling of the wood

If a plastic window is to be installed in an old wooden house and it is planned to leave the existing wooden frame, then at the stage of making this decision, the frame should be inspected for traces of decay and insect infestation. The frame must be strong, because it will be the base to which the window will be attached.

If the existing frame is unsuitable, then measurements are made taking into account the presence of this structural element of the window in the future. If there are slopes before measurements, they are removed, since the clean window opening can be much larger.

Criteria for choosing a window system

The window system consists of several components, each of which performs its function and is important in its own way.

How to choose the right glass

The surface of the glass occupies the bulk of the area of the window structure, so a greater percentage of heat loss occurs through it.

Modern double-glazed windows are characterized by the number of internal air chambers filled with an inert gas, which has a low thermal conductivity. Hence the name - single-chamber or two-chamber.

Three-chamber double-glazed windows have higher thermal insulation characteristics

A double-glazed window consists of three glasses 0.4 cm thick, installed at a distance of 1.6 cm each. That is, an indicator of 1.6 cm is the width of the air chamber.

The ability of the glass surface to resist heat loss can be enhanced by applying protective transparent or tinted layers to windows. Tinting is golden, silver, bronze, bottle blue or glass green.

How to choose the right profile

When inserting windows in a wooden house with your own hands, it is important to take a responsible approach to choosing a profile. Shutters and a window frame are made of a metal-plastic profile. It, like a double-glazed window, has a certain number of chambers in its design, which directly affects its thickness. The air in the profile chambers has a low coefficient of thermal conductivity. More chambers - higher energy efficiency of the design. For example, a five-chamber profile with triple glazing is also capable of performing a soundproof function.

Each window structure is equipped with a drip tray to remove accumulated moisture, as well as a special chamber at the bottom of the profile, which contains silica gel - these are small yellow granules. This substance accumulates in itself excess condensate, which can form on the glasses.

You can choose a profile laminated under a tree

To make a wooden wall with a pvc window look harmonious, the profile can be laminated. At the same time, the universal white color will also look good on the facade of a wooden house. You can laminate the profile under walnut, cherry, oak or mahogany - these are the most common options.. In the case of lamination under natural wood species, the window sill is also cashed in the same design, and the ebb is chosen in brown.

How to choose fittings and seals

Fittings - this is the element of the window system, which should not only have a beautiful appearance, but also be durable and reliable. The internal mechanisms of the tilt-and-turn system can withstand repeated loads. Therefore, they are made of high quality and durable material.

The lifespan of the windows largely depends on the quality of the fittings.

The sealing material for a plastic window must withstand temperature extremes and not collapse over time.

Checking products before installation

In order to avoid problems and unexpected unpleasant surprises during the installation process, it is important to first check the readiness and completeness of the products that the manufacturer must deliver to the installation site. If the delivered product has obvious defects during visual inspection, then it must be returned.

If the customer takes out the finished windows from the manufacturer's territory on his own, then this check must be carried out at the place of manufacture of the products. As a rule, the company's managers themselves offer to do this, so that later the customer signs the act of work performed that he has no complaints about the quality of the products.

The measurement results are indicated in the measurement sheet.

It is necessary to check the dimensions indicated in the act, and for reliability, compare them with the dimensions in the measuring sheet. A copy of it is given to the customer along with the contract, which sometimes specifies maximum permissible deviations. In case of discrepancy, the act is not signed, and the product is given to the manufacturer for rework.

If everything is fine with the dimensions, then the next step is to check the plane of the product - it should be even, without bends and deformations. The window system is delivered assembled, so it is important to check the sash control mechanism. Then the integrity of the double-glazed window and the density of the sealing elements inside are checked.

Installation of windows in a wooden house on an existing frame

If the house is not new, then first you have to dismantle the old wooden windows, this must be done carefully, since some elements are quite suitable for use in the subsidiary farm. When all the preparatory work has been completed, you can proceed with the installation of the window. How to properly insert windows in a modern wooden house with your own hands will be discussed below.

For the installation of windows during construction, preparation of the opening is not required

First you need to remove debris from the window box and clean it. Next comes the installation of the window sill. Control over the horizontal position is carried out using a level.

So that the window sill does not “ride” during the fastening process, its end sides can be brought into the side racks, where it is necessary to make appropriate recesses. It is necessary to fix the window sill with self-tapping screws. The window must be inserted using the unpacking method, that is, it will be necessary to remove the sashes and double-glazed windows.

Wood screws secure the window frame to the box. It is important to control the vertical position of the window frame. It is placed in the center of the opening so that there are spaces on both sides for the assembly seam. Fix its immobility with bars or wedges.

Be sure to leave a gap between the frame and the opening, which is filled with mounting foam

When filling the mounting joints with foam, the spacers are not removed until it has completely solidified. And after the foam hardens, it is cut and covered with a solution or plastic pads to protect it from direct sunlight, under the influence of which the material is destroyed.

When the frame is fixed, all previously removed elements of the window system are installed in reverse order.

Installing a window in a log house

In order to avoid troubles that may occur as a result of shrinkage, openings in a log house must be carefully prepared. The installation of windows in a log house occurs with a pigtail or, in other words, a casing device.

The installation of windows in a log house begins with the installation of a casing or pigtail, which ensures the independence of the window system from the behavior of the walls of the house. Wooden windows can also be installed in this way.

To install windows in a log house, first mount the pigtail

There are two types of casing device when building a log house. More common is the method in which grooves are made in the end parts of the logs in the opening, into which bars of the same size are placed. Usually it is 50x50 mm. This method is used when it is necessary to insert a window from a tree.

For double-glazed windows, the second method is used: a comb is cut out at the ends of the logs, on which a carriage with a groove is put on, inside which, as if along guides, the log will shrink when dried.

A gun carriage is a vertically oriented structure made of a 150x100 mm timber, having an average length of 5 cm longer than the size of the window.

Installation of windows in frame houses

Do-it-yourself installation of windows in a frame house is carried out without installing casing, since the material of the frame of such a house is not subject to shrinkage.

Scheme for installing a window in a frame house

Windows are installed in a modern wooden house by attaching them to anchor plates, which must be purchased in advance if they were not included with the window. During installation, it is important not to forget to control the position of the window in the plane horizontally and vertically.

The plates are attached to the end parts of the frame in five places. One in the center on top and two on both sides with an indent from the edge of the frame of at least 20-25 cm. Then the window is installed in the opening, a gap is left for the foam from below, placing bars under the frame, and the frame is fixed to the pigtail. The side gaps are also foamed.

Do-it-yourself installation of windows in a wooden house should not cause difficulties, subject to the technology of installation work and taking into account the specifics of a log house.

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 come across such a process yet, 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 websites, through friends I found people who had already done similar work. After he made a number of conclusions and determined the algorithm of his actions when reinstalling windows. Next, I will state everything sequentially.

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

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

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

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

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

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

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

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

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

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

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

At the end of the frame alignment horizontally and vertically, a gap of 2 cm thick should remain on each side of the entire structure - for foam filling. The height of the distance between the top panel of the pigtail and the first log is not less than 5 and not more than 15 cm - the gap will prevent 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 presentation of my experience in self-installation of double-glazed windows in a house made of timber.

Why did I decide to do my own window installation?

There are several reasons:

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

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

Removing old windows

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

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

How to prepare a place

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

Window sill installation

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

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

How to prepare a double glazing

I recommend that you install the handle before starting installation work. But the film can be removed later - so there is less chance of leaving unattractive stripes on the plastic surface. You need to tear off the adhesive strip only at the place where the handle is installed. When placing the lever on the sash, hold it with the long part parallel to the window sill.

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

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

Window installation

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

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

After wedging 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 with mounting foam, processing the cracks from the inside and outside.

Remove any hardened excess with a pruning knife.

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

Rules for secure installation

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

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

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

First: do not neglect the casing. It is also called a pigtail. Thanks to it, any windows gain independence from the impact, within reasonable limits, of the bearing walls of the building. Whether they shrink or acquire some curvature, this will not affect the integrity and functionality of the window.

General casing specifications:

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

What is a siege? The most common option is to make square vertical grooves with a side of 5 cm at the ends of the logs and then seal them with bars of the same size. But such processing of the walls around the opening is only suitable for preparing a place for wooden windows. To prepare an opening for plastic double-glazed windows at the ends of the logs, you need to make a comb, and then install a window carriage with a groove on it. The presence of a ridge and a groove will ensure that the logs slide without harming the window frame.

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

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

Then you need to make a lower jumper and also fill the gun carriages on the comb with tow. Insert the upper jumper into the hole from above, and then lower it into the groove. Then reinforce the structure with self-tapping screws, making sure that they do not touch the ridge - this is important for maintaining the relative freedom of the resulting structure. 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 the operation of the plastic window and the level of comfort during use depend on how professionally the casing is carried out. It provides the window with a safe position during the period when the house is once again slightly deformed due to fluctuations under the influence of changes in humidity or temperature.

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

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

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

How to make a pigtail:

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

The nuances of preparing a window opening

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

First of all, determine the distance to the window from the floor. The most convenient option is if the window sill is slightly higher than the horizontal plane of your desk. If there is none nearby, then be guided by a distance of 80-90 cm.

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

Having decided on the size of the opening, take measurements for the future window. Observe the utmost accuracy both when installing the casing and when taking parameters for the design of the double-glazed window itself. Qualitative measurement is one of the most important nuances that affects the quality of all subsequent work on the installation of a double-glazed window into a window opening.

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

Installation nuances

The finished metal-plastic structure is placed after being ideally pulled out in the foreground or deepened into the wall. The main product is fixed with self-tapping screws, screwing them into specially prepared grooves.

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

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

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

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

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

Features of installing a window system in a wooden house

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

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

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

Window cutting pattern

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

Preparing the Workspace

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

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

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

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

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

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

Window sill installation and window preparation

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

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

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

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

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

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

Window installation

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

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

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