How to properly install plastic windows in wooden ones. Self-installation of wooden windows in a wooden house

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 wood during the drying period.

For 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 that easily deforms window unit. The doors do not open after such an impact, and the frame is severely 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 if special technology is followed. We will consider this in our article.

How to properly install a plastic window in a wooden wall?

In order to eliminate the pressure of the wall on the window block, craftsmen came up with special “sleds”, popularly known as frames or casings. The idea of ​​this technology is very simple: a vertical protrusion-ridge is made with a chainsaw on the end part of the window opening logs.

A window carriage is placed 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 A plastic window installed in a casing box is not affected by the destructive forces of deformation of the log house.

The pigtail performs several important functions in a wooden wall:

• prevents logs from moving from the vertical;
• does not interfere with the vertical shrinkage of the log house;
• strengthens the wall in the window opening area.

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

Features of installing plastic windows in wooden walls

You need to be very careful when cutting the ridge at the ends of the window opening, marking it using a level. Any deviation from the vertical and any inaccuracies in the tongue-groove joint will negatively affect the operation of the socket, disrupting its free movement along the wall.

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

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

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

First you need to cover the ridges 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 this, the lower lintel of the frame is placed in the window opening. Then carriages (side bars of the casing) are stuffed onto the ridges. The second jumper is inserted into the upper cutout of the carriage and lowered to a horizontal position. Having assembled the box, you need to carefully fasten it 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 not allow it to slide along the wall.

All the cracks remaining in window opening After installing the pigtails, fill them tightly with tow. Next, using standard technology, the installation of a plastic window is carried out with all the accompanying operations to ensure protection of the junction area with the casing from moisture, heat loss and noise penetration.

The gap between the frame 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, remove the top trim (it is attached only to the frame) and, removing the unnecessary “compensation” board, put it back in place.

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

Until now we have talked about the installation of plastic window blocks in new log buildings. But is such technology necessary if we are talking about an old wooden house?

Experienced craftsmen say that a socket is necessary here. The fact is that any log house, even after 5 years of shrinkage and shrinkage, does not stop changing its size. Wood is a living, porous material. Therefore, when it rains outside, the logs and beams swell. During the hot summer, the reverse process occurs and even an old hundred-year-old log house loses several centimeters from its previous “wet” height.

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

Therefore, the owner has two options:

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

Concluding our review, let's say that installing a plastic window in a wooden wall is not very difficult process. With a careful and attentive attitude to the work, it can be done efficiently on your own, without involving “expensive” craftsmen.

Addition to the article

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

Good afternoon
Installing a plastic window in a log house is clear, but how is a plastic window installed in a house on the gable, in which an opening for the window is formed from an 80x100mm board?

This installation option is simple. Just before installation, it is advisable to attach an antiseptic 20x20 mm strip 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 will not need to install a batten.

We place the plastic window on spacers (to create a gap into which the foam will be blown). After this, we carefully go through the entire contour with sealant. You can additionally secure the window in the opening using metal mounting plates. However, foam alone will hold the window securely.

Didn't move away from the outer edge window block, and The house is old, the window unit is level and in some places there is a 50 mm board facing the outside of the street, and now it’s getting cold. What can be done?

The best option is to remove the window unit and install it in the opening with a quarter space, as shown in the previous diagram.

An acceptable option is to make a thick board around the window block outside the wall so that you get quarters that cover the joint of the window block with the wall from blowing. Seal all leaks and gaps with foam or tow.

Installation of PVC window in a wooden house

Plastic windows are used almost everywhere today - and in residential buildings, and in administrative premises, and in city apartments, and in country houses. At the same time, it’s one thing to glaze a rigid opening with “plastic” reinforced concrete panel, there are no special problems here, but the installation and installation of PVC windows in a wooden house is much more difficult - the openings in its walls need to be properly prepared and strengthened so that the heavy window stays firmly in place.

The correct technology for glazing a wooden house with plastic windows first of all requires complete shrinkage of the house. Until the structure of the house and its foundation have taken on their final shape and position, it is not recommended to install windows - if certain elements move, damage to the window unit and double-glazed windows may occur. So they built a house, let it settle and sit on permanent place, and after that we proceed to glazing with PVC windows. This requirement is equivalent to all other wooden buildings, be it a bathhouse, barn, gazebo, etc.

To prevent damage to the window unit due to unexpected movement or shrinkage of the walls, you need to make a frame in the opening. This is a structure made of molded timber that is mounted in the opening.

In order for the window frame to take its rightful place, you need to cut out the central tenon on the sides of the window opening in the opening. To do this, we divide the surface of the opening into 3 segments, leave the central one in place, and remove the side ones by about 5 cm. Before installing the elements of the frame, you need to cover these resulting protrusions with tow - it will prevent squeaking and increase thermal insulation.

Naturally, you need to prepare a recess in the elements of the pigtail. To do this you need to take a beam required sizes and a cross section of about 10-15 cm and hollow out a recess for the tenon along the center line. You also need to remember that the length of the beam should be approximately 5 cm less than the opening and at the same time larger than the window by 5 cm.

Window sill installation

When the pigtail is ready, you can begin installing the window sill. We must not forget about this - first the window sill, and then the window! The process of working with a window sill is described by the following instructions:

• you need to cut grooves of small depth in the sides of the box for the window sill, without them the window sill will not hold well;
• then, using thin spacers made of wood or plastic, we level the surface;
• We insert the window sill into the grooves and fasten it with self-tapping screws. The fastening must be done so that the screw heads are hidden by the window lining, and rubber washers must also be placed under the head.

Window installation

When the window sill is installed, the installation and installation of PVC windows begins - in a wooden house with a small number of storeys, you can do it yourself, especially since the cost of specialist services when calling them outside the city will be rather high.

• first we prepare the window block, dismantle all the sashes and removable double-glazed windows;
• then we insert the box into the opening and level it with the help of bars;
• We fix the window with anchors, they should be installed from the sides and top;
• the space between the window and the opening is filled with polyurethane foam.

If the window is level, you can return the double-glazed windows to their place; they must be fixed with a special bead. Then the sashes are hung and the window fittings are adjusted. When everything is in place, all remaining cracks are foamed; it is also a good idea to seal the joint between the window and the window sill with sealant. Don’t forget to foam the cavity under the window sill as well.

The final stage is the installation of the low tide. It is leveled, fixed with self-tapping screws, and foamed in several places.

Do-it-yourself installation (installation) of metal-plastic windows. Instructions for installing metal-plastic windows

At the height of the renovation season, the most common type of work is the installation of metal-plastic windows. To be more confident that the workers you hire fully comply with the technology for installing metal-plastic windows, it’s a good idea to know the main stages of this process yourself.

IMPORTANT! To make cuts, do not use a metal wheel due to the risk of it breaking.

It's better to take regular saw or a grinder with a circle on concrete (the latter, however, will generate a lot of dust).

Photo 1 - Cuts in an old window frame for dismantling

• The frame is removed piece by piece using a crowbar. We dismantle a wooden window sill in the same way as removing the frame, concrete window sills in good condition not dismantled, but after completion of all installation work lined with tiles or any other covering with a layer of insulation.

• We clean the window opening, prime it and after the primer has dried, apply markings: mark the places where the window is fastened.

  The fastening pitch should be no more than 70 cm on each side of the window. The extreme fasteners from the corners of the window frame should not be removed more than 5-15 cm.

• The screws used to fix the frame must be fixed in the metal inside the PVC profile (by the way, the presence of a reinforcing component is what distinguishes a metal-plastic window from a simple PVC window).

  Installation of metal-plastic windows should be done only with special metal screws (4 mm in diameter).

  Installation and installation of PVC windows in a wooden house - there is nothing complicated

  Drills are placed at the ends of such self-tapping screws to ensure that the fastener enters the material.

When using another fastening screw, you will first need to make holes in the window frame and then insert the self-tapping screw into them.

If the window size exceeds a square of 2x2 m, you need screws 12 mm in diameter.

• Another fastener− anchor plate. We place fasteners along the perimeter of the frame at the previously marked points. We insert the frame into the window opening and mark on the surface of the walls the places for drilling the second row of mounting holes. The recesses for placing anchor plates should extend into the walls by 2-4 cm - this will make it easier to carry out work on installing slopes and window sills later on.
• We align the window strictly horizontally using the mounting level.

  To do this, we place wooden wedges under the window frame, where necessary.

Photo 2 - Leveling the window. Using wooden wedges

• We fix the top anchors, and then the side ones.
• Having strengthened the external waterproofing with the help of PSUL, we fasten the ebb going under the window with self-tapping screws 4 mm in diameter and 9 mm long.
• We regulate window fittings and put the double-glazed windows in place.
• You only need to foam the gaps between the frame and the window opening when the windows are closed!

  It is prohibited to leave windows for ventilation during installation, otherwise the mounting foam will bend the profile in an arc, which will lead to cracking of the glass and damage to the window. Foaming of wide gaps (from 2 cm or more) should take place in stages with a break of 1-2 hours. After drying, the foam must be protected from ultraviolet radiation with a special sealed film, plaster or panels.

IMPORTANT! After foaming, the window must remain closed for at least another 12 hours.

• We install a window sill.

  After taking measurements, the blank for a window sill of standard sizes is adjusted to the length and width of the window, taking into account that the window sill should go under the window and should also be slightly recessed into the walls on the sides.

If the measurements are correct and when trying on the window sill, the slab fits under the window a little tight, you can start fixing it. The window sill must also be leveled, placed on wooden wedges and secured with adhesive or polyurethane foam. In the latter case, spacers or a weight are placed on the window sill for at least 12 hours so that the foam, when expanding, does not knock down the exposed horizon.

• We install fittings on windows.
• We install slopes (technologies for installing plasterboard, plastic or plaster slopes vary).
• We seal the joints of the window elements and clean the frame from the protective film.

Installing metal-plastic windows with your own hands is also possible, but to do this you must know about the technological details of the process or purchase metal-plastic windows, the installation of which you will be able to install, following the factory instructions.

$ Installation of metal-plastic windows.

The cost of installing metal-plastic windows will directly depend on the type of window (fixed, hinged or combined), the type of wall opening and its condition, device assembly seam, installation season, as well as the total amount of work. On average it is $20-30 per m².

The estimate for the installation of metal-plastic windows must contain the entire list of works: delivery, lifting to the floor, dismantling old windows, removing garbage, installing windows, sills, window sills, slopes, etc.

• Kyiv - from 350 UAH.

• Moscow - from 4,100 rubles. for the installation package.

Shrinkage is a natural and inevitable process everyone wooden buildings. In this regard, the installation of plastic windows in log houses differs from standard installation.

The highest percentage of wood drying was observed in the first two years after the completion of the log house. The height of the walls, as a rule, is reduced to 1.5 cm per meter of masonry. How to insert a plastic window in a wooden house?

What devices are needed to achieve this goal? The answers to these and many other questions are presented in this article.

Casing

The main stage of installing double-glazed windows in a wooden house is fixing the frame in the window opening. The casing ensures that windows are independent from load-bearing walls structures.

In other words, when the frame shrinks, the window structure remains “intact” and is not subject to deformation vibrations. The window frame takes on all shrinkage loads and strengthens the walls of the building in the area of ​​the opening.

The casing is a box made of thick boards. Install it in the opening, and then perform PVC installation designs.

The box is held in place by grooves located in the side posts. It is unacceptable to use any fastening elements, including polyurethane foam. A compensating gap is left above the structure itself, designed for the maximum amount of shrinkage of the logs.

There are several options for installing the pigtail:

• cutting a groove in a log and placing a wooden block in it. Self-tapping screws (embedded block) are screwed into the last of these elements through the side posts;
• sawing out a tenon at the end of the opening log and cutting a groove in the side posts of the box (the “into the deck” method);
• the location of the tenon is on the side posts of the structure, the groove is at the end of the opening logs.

Preparing window openings

It is quite possible to install high-quality plastic windows in an old wooden house with your own hands.

How to install plastic windows in a wooden house

The main installation rules are to follow the sequence of actions and take into account the construction features.

First, measure the distance of the window from the base of the floor. The most optimal parameter is 80-90 cm. Ideally, the window sill is installed higher desk, the standard height of which is 80 cm. The upper and lower boundaries of the window opening are marked using professional tool– water level.

Its height should exceed the same parameter of the inserted plastic window by 13 cm, and its width by 12-14 cm. Plus, 1.5 cm is left on each side for sealing with polyurethane foam.

The next stage is preparing the window opening (measurements, installation). By using building level make markings for cutting it. Maximum accuracy in measurements and installation of the casing itself is especially important. The quality of the installation work will depend on this. After the opening is ready, a tenon is cut out at the ends of the logs on the sides of the structure.

The lower and side parts of the rough window are sheathed with jute.

A casing is made from well-dried wooden blocks, the installation of which is carried out starting from the window sill. The structural elements are fastened together with self-tapping screws, and the joining areas are treated with sealant. The small gap in the socket is filled with tow.

PVC window installation

The finished window is installed either perfectly aligned with the front edge or slightly recessed into the house.

Fix the frame to the previously fixed structure using self-tapping screws, having previously drilled holes for them. You can install double-glazed windows into a wooden house (not made of timber), taking into account all the details. We are talking not only about the accuracy of markings and the choice of high-quality material for casing, but also about the correct selection of fasteners for fixing the window.

External seam waterproofing can be done different ways: vapor permeable or self-expanding sealing tape, one-component acrylic sealant.

They will provide protection for the polyurethane foam from moisture and direct sun rays. WITH inside the seam is covered with vapor barrier tape. Glue it until foaming to the end part of the frame with a thin strip. After the seam is treated with polyurethane foam, the protective paper from the adhesive strip is removed and glued to the casing. The window sill is installed and the starting profile is screwed to the edge of the frame before the sealing mass hardens.

Instructions for installing wooden windows.

The main feature of installing window structures in a wooden house is that for the entire service life of the frame, unlike a concrete, brick or stone house, it behaves very unstable.

In other words, wooden structures have the property of “shrinkage”. And if you don't take this instability into account during installation, serious problems can arise.

There is an opinion that the frame does not shrink until the first year after installation, and then the house does not change its parameters.

How to install PVC windows in a wooden house

But it is not so. In fact, a wooden house stands, this is especially noticeable in the first year, and then, for at least 5 years, this process does not stop (and in some regions, depending on weather conditions, the log continues to shrink throughout its life).

As the wood (timber or logs) has dried, the height of the house wall for each foot of wall can be reduced by 1.5 cm. If the wall height is 4 meters, the frame can be "compressed" by as much as 6 inches. And now I can imagine what will happen to the window if you leave only a standard gap for installing foam plastic 2-2.5 centimeters thick? It is correct that the frame is at least deformed and the wedge will be jammed.

However, installing metal glass windows in a hall is a very viable option.

However, only on condition that the opening is installed by an observer (or, as it is called, it is an okosyachka system), which will ensure independence from the window by building the envelopes (walls) of the house and taking care of all the loads. In this case the window:

• Do not allow magazines to move out of the vertical opening of the window;
• does not interfere with the vertical deviation of the walls;
• Strengthens closed structures in the area of ​​window openings.

To have an idea of ​​how the window is installed in the corridor, we have prepared detailed instructions, describing all stages of the installation work.

First, let's look at what a chassis is and what parameters the system currently uses.

Main housing options (end)

The simplest design is a 50x50cm piece of wood inserted into a vertical groove of the same size, with the end of the log in the window. This version of the window is used only during installation wooden windows. And since we are thinking about installing a metal-plastic window in a log cabin, there is no need to carefully consider this option.

In the second version of the window, a tip (the so-called comb) is made at the ends of the magazine, on which a gun holder with grooves is installed.

Window hinges - vertical beam size from 150 to 100 centimeters, excluded at the ends of the grooves 50 50, which are inserted into a plate of size 150 to 50 with tenons at the ends (horizontal bridges).

Due to the log of the log, when the house's compression slips into the groove, do not press the window structure or deflect vertically.

Sometimes the tip is made on a dolly, but the groove is in the logs, while the basic operating principle of this version of the body is not changed.

Be careful!

When assembled, the window should be 7-8 centimeters higher than the window opening (this line remains to be shaken in the house).

Instructions for installing plastic windows in the hallway

The window is configured like this:

• The hole houses the lower part of the housing
• combs are packed in bagged bags (intermediate insulation)
• the ridges on the window frames are filled
• At the top holes, the top bridge is inserted and lowered into the gutters.

The entire structure is secured with screws.

In this case, you need to make sure that the screws do not "lock" the ridge, otherwise the case will not be useful. The cracks between the logs and the casing are jammed like hell. By the way, the curtain not only seals the holes, but also saves you from debris when the house shrinks.

Further installation of metal-plastic windows in a wooden house is practically no different from the usual installation of window structures in an apartment. In other words, normal window installation is carried out according to fumes, noise and thermal insulation, detailed description which can be found in the article “Features of installing windows with your own hands.”

The range that remains between the walls of the frame and the windows is filled with small thicknesses, which are pre-wrapped with a stick.

Since the house sits, the slabs must be replaced with others that are more suitable. To make it easy to change panels, the panel on which the panels are installed is attached to the window only. So when replacement is necessary, simply remove the piston, change the boards and place the clipper in place.

An experienced specialist must know not only the technology for installing metal-plastic windows, but also the technology for building a house.

Only in this case, it will not be able to correctly determine whether the window structure can be installed in each individual case, but also, if necessary, install the classic frame into the hole.

If your obsady bunker role is wearing a box that was left over from old wooden windows (in other words, when you removed the lining to most accurately measure the hole, they discovered that okosyachki did not), then installing plastic windows has two options:

changing the window panes below the window;

2. Significantly reduce the transparent part of the window, because the thickness of the window + frame + foam gap is added to each side of the window structure.

And most importantly, never agree to install a metal plastic window in the hall without first installing the window in the hole.

Even if your house has been standing for decades, and you think that the frame is already completely “compressed”. Remember that wood is a “living” material that “breathes” throughout its life with all the ensuing consequences.

Plastic windows are firmly reinforced in modern construction. They have many positive advantages, which allows them to be used in various types of buildings, including wood construction. But the specialty of their placement in a wooden house differs from installation in classic brick buildings. So how to solve this problem? How to insert a plastic window into a wooden house?

Differences in installing metal-plastic windows in wooden houses

The main problem with installing plastic windows in wooden structures is that the structure of the wood is greatly reduced after construction due to drying of the material.

Yes, and during further use various types movements are possible.

Depending on the building material, shrinkage per meter of building height is associated with such indicators.

But in general, the movement can be up to 300 millimeters.

Therefore, all builders advise not to carry out Finishing work. When inserted in accordance with generally accepted requirements, windows simply deform under such pressure. But what to do, don’t leave the same house without windows, especially seasonal changes as before, depending on the humidity and ambient temperature.

At the first stage, it is necessary to carry out some preparatory work.

If the house has just been built, it is necessary to remove construction dust and debris, take measurements and draw a drawing of the future installation window system. an old house made of wood requires the following preparation:

• Dismantling (destruction of old windows).
• Removing residues and residues.
• Measurements and calculations of the parameters of the next window.
• Restoring the condition of load-bearing wooden structures, trimming window openings (there should be no rotting or mold.

  The cleaned areas are cleaned and the wood set is puttied).

• Selection of manufacturer and order of window systems.

What you need to install windows

You need tools to replace or install windows.

• Electric drill with drilling series.
• Construction level and roulette.
• Chisels.
• Mallet.
• Screwdriver.
• Wedge wedges.
• Fastening elements (plates, screws).
• Collection of foam.

It is also advisable to have a partner involved because the windows are very difficult to install on their own due to the size and weight of the insulated glass.

Frame.

What is it, its type and design features

To protect the window from the walls, it is necessary to plan and install a so-called floating base in which the window frame with double glazing - body. In particular, its presence is important for the veranda, where the length of the window system can reach several meters.

You can post wooden planks with an important hole.

Structurally, it looks like there are plates on the periphery of the aperture. The housing is secured by grooves, at points such as gaskets, patch or other natural fibers, they cannot be sealed with foam. During installation, the gap is always at the top.

By using this design, the built-in double glazing will be protected from the effects of shrinkage.

The housing mounting method is divided into the following types:

• Fastening in the tip.

  Place thorns on the sides of the body, which are inserted into the grooves of the holes.

• In a built-in beam. At the end of the window aperture, insert the rod to which the stand is attached.
• On the rooftops. The ends of the window opening logs provide finials and grooves on the body.

The main thing when installing such a system is to ensure the accuracy of the installation; incorrect accounts will be overloaded with deformations and the inapplicability of such a system.

The design of the floating body reliably protects against mechanical stress when the wall moves due to shrinkage processes.

How to make a casing (window)

There are two production methods. It's just the exact groove system described above. The manufacturing technology of a complex window is different.

IN open window a ridge is inserted into which the gutter system is inserted.

This fixation is much safer, since the housing can slide and compensate for the pressure of the wall.

For this purpose it is used wooden beam, in which the intestine is cut with a chisel (depth about 5 mm).

On the window cut, use a saw to cut out the ridge cap to the dimensions that match the grooves. The end faces form the slot and the tip, which make up the entire system.

After preparation, the entire window system is installed in a window with longitudinal grooves. Wood nails used to connect housing elements.

Assemble the window, proceed directly to installing the plastic window.

Installing a window into a hole

I leave the windows open before installing.

To do this, twist and pull the top pin.

Gaps must be created at a height of 40 millimeters, at the bottom 30-40, on the sides up to 20 mm. Then fill them with precast foam. For this wooden frames installed under the window frame.

You can set the frame in two ways.

Option 1.

Drill holes through the frame at the ends and attach them with screws. However, this method is burdened with a reduction in the tightness of the window system and, consequently, a decrease in thermal insulation. Use it only if it cannot be determined in any other way!

Another variant. Attach mounting plates (sold as a panel for attaching profile skeletons) to the outer edges of the frame.

The free edges of the plates are bent to contact the surface of the window and attach to the press.

DIY installation of plastic windows in a wooden house

In no case is it forced into the ridge on which the housing is attached.

In this case, it is necessary to strictly monitor the level of the frame in all planes. You cannot dock a window if one of the parameters is broken!

Once the frame is secured, the hinges are hinged and the wings hang.

Once the foam dries, you must take care to protect it from the harmful effects of ultraviolet light and temperature.

Plastic window covering in a wooden house - great option, but it can be made of wood.

And don't forget the swelling that protects the window and walls from excessive humidity.

The process of installing PVC windows in a wooden house requires precision and compliance with technology, if violated, double glazed windows do not provide the required time. Taking into account the installation rules, the service life of plastic windows in old houses increases by several decades.

Instructions for installing a plastic window in a wooden house with photographs and

Many people believe that installing a plastic window in a wooden house is a very difficult job.

This is due to the fact that wooden houses eventually become natural shrinkages. But if you know the characteristics of housing and follow certain rules, nothing is truly impossible.

What to consider during installation

The configuration of window openings in wooden structures, although imperceptibly, constantly changes throughout its life.

This is due not only to the shrinkage of wood, but also to its ability to absorb moisture when deformed with temperature changes. Therefore, instability is characterized by the parameters of holes in such structures.

Recommendation that installation of plastic windows can be carried out within 3 years after construction wooden building, is not entirely true. Shrinkage occurs in stages. Most of moisture evaporates in the first year, but the process of “shrinkage” continues for many years.

Experts note that this period averages 5 years, in some regions (taking into account the climate) it never ends. This sets special requirements to build a structural element, such as a window, which is installed when installing window frames.

Order for installation

Receipt

If the house is new, you need to check the window opening geometry.

Even if all dimensions were strictly maintained during construction, shrinkage distortion may occur.

PVC windows - no. The rectangle is strictly formed without any deviations. Therefore, the correct configuration of the window openings must be achieved (if movement is sensitive). The methods are numerous and simple.

The same applies to a house that is already in use. After removing the pre-installed window, the installation window of the plastic window is checked.

It is necessary not only to clean everything from dirt to the level, but also to carry out high-quality wood processing using antiseptic and non-flammable compounds.

Housing (casing) installation

This structural element located in the window opening, regardless of the material from which the frame (window part) is formed.

It is in this context that it is attached. The task of the body is to eliminate the influence of the deformation of the walls of the house on the window, so that it is “independent” of various movements and arising mechanical loads in order to maintain its integrity.

How to install plastic windows in a wooden house

In other words, no matter how the aperture geometry changes (wall compression, mud base), it should not affect the structure itself.

There are several housing options.

The choice of the optimal dependence depends on the type of pillows (shaft, log), their characteristics and many other conditions. By the way, not all windows are suitable for PVC windows, which should be taken into account.

The "mounting" of the frame should be less than the opening of the window to prevent its destruction due to vertical displacements of the wall elements. Let's take as an example the simplest and therefore often used version of the window, which is suitable for “plastic”.

Each owner chooses for himself necessary tool. The main thing is to understand the principle of consent and action.

At the ends of the side walls of the hole, it is solved vertically, along the entire height of the recess (groove). He predicts it will be inserted into cars that are cut into (hole-sized) thick slabs along the center line, from which there is a “spike.”

For vertical wall movements, the projection will slide along the "groove" and the deformation body (and therefore the window) will not be exposed.

Alternatively, "tips" are made at the end of the beams (logs) and the grooves are sawn in a cart. But the operating principle is the same.

Bottom part ( support part) is made in such a way that it has “tips” on both sides, which are inserted into grooves on the side walls of the hole.

By analogy, there is also top part framework. Its fastening in one design is made using screws and knives. The main thing is that the case is not attached to the wall, and then the feeling of its installation is lost.

Window settings

PVC frames have special fasteners with which they are attached to the window.

When purchasing window units, you need to understand (at the point of sale) how this is done, since different manufacturers fasteners may vary.

When defining a window in a field, you need to slightly raise and fix this position (break), create a small difference (for further “penny”).

sealing

All spaces between the block and windowed window fixed using polyurethane foam.

And their processing is carried out on both sides (inside and outside the building). After final drying, the excess can be cut off.

• "Plastic" is very sensitive to low temperatures- he becomes fragile.

  Therefore, installation of such products at -10°C or less is not possible.

• There is no point in buying uPVC windows if there is no casing on all the openings. It is their geometry that determines the size of the plastic blocks. This article describes all the selection rules quality window- reading.
• The dimensions of the “spike” (“groove”) are usually chosen at a height of 5 cm.
• It should be noted that it UV destroys the foam installation, so this “overflow” must be protected somehow.

Quite often, owners of private houses or country dachas prefer to make corrective changes to their housing, for example, installing plastic bags or choosing more a secure door to protect your own property. It is these elements that perform protective function, therefore they must be of high quality and reliable in all respects.

PVC windows in a wooden house

Owners of private housing often wonder: is it allowed to install plastic windows in a wooden house, especially if this event concerns old buildings? This question can be answered unequivocally: of course, it is allowed. Moreover, professional builders They recommend such structures for any property, including those made of wood. You can carry out the installation yourself if you have even a little knowledge of construction skills, and, of course, during installation it is necessary to take into account the features of wooden buildings.

The technology for installing PVC windows in wooden buildings provides for some differences, so this process will require a diagram of all manipulations, which will be correctly and correctly calculated. The most important thing here is to consider that wooden base the house tends to sag, which can affect new window coverings. If the order of work is carried out according to the correct scheme, then all manipulations with the windows will not lead to disastrous results, and subsequently the shrinkage of the wood will not disrupt the installation of the plastic material.

The procedure for installing PVC windows in a wooden building

Having chosen PVC window coverings for your home, no matter whether it’s old or new, it is recommended to install it using the “casing” or “jam” technology. This technique will prevent the process of window deformation, regardless of the base that was chosen for the manufacture of the building material.

According to statistical studies, a house made of natural wood can shrink by about 35 centimeters. The amount of shrinkage depends on the base that was used in the construction of the wooden structure. A year after the construction of the building, the house may sag by:

1. 45-65 centimeters if the walls were built from rounded logs.
2. 35-45 centimeters, if ordinary timber was chosen as the basis.
3. 15-35 centimeters, if the walls of the building were built from laminated veneer lumber.

These parameters should definitely be taken into account, since shrinkage of the house can “press down” installed windows to the main structure. As a result, the window coverings will succumb to the deformation process and will be difficult to open and close. Therefore, experts do not recommend installation in a building that has not yet shrinked. But it’s not only new buildings that can be damaged; older buildings can also experience similar difficulties. A specially designed diagram created by professional builders will help you avoid installation errors.

What steps are important when installing PVC windows in wooden buildings

First of all, when installing window coverings from plastic base must be carried out preparatory work, which include several activities:

• The old window frame is completely dismantled;
• Debris and dust are thoroughly removed;
• the size of the window frame is measured and the necessary calculations are made;
• at irregular shape hole, which is intended for a new window, its shape is aligned. For manipulation, you can use a special sealant or putty material for woodworking;
• It is determined which design design is most suitable for a wooden house, and the color of the PVC window is selected.

The preparatory stage allows you to accurately determine the dimensions, think about how many sashes you would like to see on the new window, and what color is more preferable for the harmonious combination of the window frame with the main structure of the house. After completing the first stage, you can contact a window production company and order the type that will satisfy all the customer’s wishes.

Installing a new window

After the selected window coverings are delivered, and the first preparatory stage finished, you can begin the main process - installing the window frame. For this stage you need to prepare the following tools:

• wood drill and screwdriver;
• level used in construction, measuring tape;
• fasteners in the form anchor bolts and plates;
• polyurethane foam and a spray bottle with plain water.

During the installation process, you may need additional tools, for example, pliers, wrenches for tightening bolts, wedges for spacers, so it would be a good idea to prepare them in advance as well. It is recommended to find a partner during installation in order to correctly perform some manipulations with the window covering. Next, you should install the frame so that the shrinkage process does not adversely affect the original shape of the window frame.

The process of making a pigtail

The final installation of a plastic window in a wooden house can only be done after making the frame. In order to independently produce this structure, which will support significant weight from the load-bearing walls of the building, you need to prepare a high-quality wooden beam. The size of the latter is 10 by 15 centimeters. Using a construction chisel, it is necessary to make a cut on the base to create a connecting groove, and its width should be 5 centimeters.

Using a chainsaw, additional longitudinal cuts are made. All manipulations with the beam are carried out using a building level to prevent distortion on the structure. The main riser of the window frame is installed in the finished grooves, and the desired opening is formed. In this process, a building level is also used.

The last stage of installation of a PVC window

IN ready-made system Okosyachki install plastic windows using special fasteners. To make installation easier, you can remove all the doors from their hinges by simply removing the retaining pin. Thus, the weight of the window covering is significantly reduced, and installation is easier.

The installation of this element must be controlled using a building level to prevent misalignment. The installation procedure is as follows:

• fasteners connect the pigtail system;
• leave a small distance at the bottom using a wooden wedge, which will be removed later;
• the window frame is installed in the frame system and securely fixed with fasteners;
• the window sashes are installed in their original place;
• The cracks and gaps are filled with polyurethane foam, and the wooden wedge is removed.

Of course, installation of plastic windows in wooden building- both in the new and in the old - cannot be called simple and easy. However, any difficulties can be avoided if you adhere to the recommendations of experts and a properly developed scheme for this process. If you still encounter difficulties when installing window coverings, you can watch a training video.

Plastic double-glazed windows have best characteristics than wooden structures. Due to their high performance indicators, such windows are actively used in both concrete and wooden buildings.

Installation of plastic windows in a wooden house differs from installation in concrete and block buildings. The technology consists of lengthy preparation, the main objective which is to prevent the destruction of the double-glazed window from shrinkage of the house. During work, you need to follow certain rules that will help extend the life of the structure.

Installation

Installation of double-glazed windows, regardless of the age of the house, is practically indistinguishable. In both cases, installation begins with the casing. It is this design that protects the window from destruction during the process of shrinkage and natural expansion of the wood.

Installation of plastic structures requires specific skills and knowledge from the master, without which the work cannot be carried out. If you have no experience in carpentry, it is better to turn to professionals. The main difficulty in assembling the casing for a window is assembling the tongue-and-groove lock. It is this fastening that provides reliable connection parts and protection of the frame from deformation.

The shrinkage of an ordinary wooden house can reach 20-30 cm, which is noticeable when using structures made of metal and plastic, the shape of which does not change over time. The degree of shrinkage depends on the type of wood. So the average shrinkage a year after the assembly of the log house is:

• for houses made of logs 50-60 mm;
• buildings made of timber 30-30 mm;
• buildings made of laminated timber 15-30 mm.

These figures are small, but they are worth taking into account. Shrinkage of the building in the first year of construction can lead to windows being pushed through by the upper rims of partitions and walls.

Shrinkage of a building lasts up to 5 years, it depends on air humidity, the size of the house and the time of year. But even after 5 years, the house still “breathes”, which is why PVC products are installed with casing in old buildings.

Preparatory stage

To figure out how to install plastic windows in a wooden house, you will need to follow certain instructions. Before assembly, the following work must be done:

• dismantling and removal of the old structure (for old houses);
• cleaning the opening from dust, wood chips and old paint;
• taking measurements of the opening and calculating the dimensions of the future window;
• preparation of a diagram or drawing;
• alignment of the walls of the opening in case of symmetry violations;
• for leveling, use a primer, sealant and putty;
• choosing the type of future window (sash format, material color and size of the entire structure);
• identification of the company of the product.

When all the work described above has been completed, a window is ordered according to the measurements of the opening. There are several installation features plastic products.

Installation of the structure

After delivery, the window must be kept in room temperature. For installation you will need:

• screwdriver and drill bits;
• mallet and chisel;
• anchor fasteners;
• wedges for spacers;
• polyurethane foam;
• key for PVC windows;
• pliers;
  level and roulette.

The installation of a plastic window in a wooden house is carried out in pairs, since it is easier to lift and fasten it together. The weight and size of the glass unit does not allow it to be carried alone.

Note! It is recommended to install PVC windows in calm and warm weather (above minus 10).

Functions and types of casing structures

A casing is a box made of boards installed around the window along the perimeter of the opening. The design of the structure allows you to install it yourself so that it “floats” inside the log house and does not depend on the shrinkage of the building. To attach the casing to the frame, grooves are used; they are placed on the sides of the window opening. The casing itself is seated at the ends on spikes.

To prevent the casing from being blown out in winter, it is fixed with tow, linen or fiber sealant.

A small gap is left in the upper part of the casing, which maintains the integrity of the structure during shrinkage. After assembling such a frame, the movements of the frame do not affect the window in any way, and most importantly, shrinkage cannot harm the structure of the double-glazed window.

In this case, the walls will shrink, and the window will not be damaged. Casings are divided into several types, depending on the types of fastening:

• In the mortgage timber. The fastening is based on a block placed in a groove at the ends of the opening. In addition, it passes through the casing posts.
• Into the thorn. Such structures have a special spike that is installed on the side elements of the casing. The groove is located in the logs of the opening.
• Into the deck. The tenon in this case is located at the ends of the logs. There is a groove in the casing posts.

The frame is a floating mechanism, during installation of which it is impossible to deform the plastic window. Do-it-yourself installation of wooden windows is carried out using a different technology.

It is necessary to carry out calculations very accurately, because even with a slight error the risk of deformation of the box will increase. In addition, the structure may not be airtight. Correct installation boxes - required condition window service quality.

Making a joint

There are simple and complex pigtails. Each of these types of design has its own advantages. For example, a simple frame can be quickly erected, while a complex frame eliminates vertical deformation of the window. When creating a simple pigtail, the option already described in the article is chosen - using grooves and bars.

A complex system requires sawing out a ridge in the opening. A carriage with grooves is put on it. This design option is more reliable. During the shrinkage of the house, the ridge moves in such a way that deviations plastic construction vertically are excluded.

The casing is made of bars. Using a chisel, you need to knock out a groove in the center of the beam with dimensions of 0.5x0.5 cm. One of important points is to mark the ridge with your own hands. How high-quality the window design will be will depend on the accuracy of the markings performed.

When the ridge is ready, you need to start forming the opening. The beams should be installed using a level. In this case, the gap for shrinkage is taken into account. It is 0.5 cm on top and 1 cm on each side. It is better to strengthen the frame, which is made of beams, using dowels. The resulting cracks are sealed with tow. Then install plastic frame.

Installing a plastic frame

After preparing and installing the pigtail, you should begin installing the plastic structure. Installing a window without casing is a mistake. First you should check the parallels. The gaps between the frame and PVC double glazing. For foaming, leave 3 cm on the side and about 5 cm on top. Then you can begin directly installing PVC windows in a wooden house.

The structure must be attached to its designated place using special elements. They can be purchased at any hardware store. Such fasteners are metal plates with holes.

Advice! It is better to use special fasteners, because the use of self-tapping screws does not ensure the tightness and thermal insulation of the structure.

Installation of a plastic window is carried out with a level. If this rule is not followed, the structure may end up tilted. This circumstance can significantly reduce the aesthetic appearance of the window and its performance.

Advice! Before installing the structure, the sashes must be removed. This will make the window lighter, which will have a beneficial effect on ease of installation.

After fixing the window in the opening, the resulting gap should be foamed. For a secure fit installed structure use a bar. This will prevent the window from moving during foaming. When the foam dries, they should be removed. When installing windows in a wooden house in a casing, you should be careful. In this case, you will have to determine the correct installation position of the screws. The window should not be secured in the ridge area.

At this point, the window installation process can be considered complete. Now all that remains is to put the flaps on and let the foam dry. This method of installing a plastic structure in a dacha is correct. If you are not sure about own strength, you should call professionals. However, installing a plastic window yourself is a significant cost savings. To do the job as efficiently as possible, you need to follow the instructions.

conclusions

Installing a plastic structure in a wooden house is as simple as possible. To do this you will need to do accurate calculations and prepare a specific set of tools. All work is carried out with the utmost care. This is necessary for the long service life of the glass unit.

During work, it is necessary to follow a certain sequence of actions, as well as follow some rules. It is important to take into account the peculiarities of shrinkage of wooden walls. If you follow the advice of professionals, plastic double glazed window will serve well for many years.

Video editing will help you cope with the task as efficiently as possible:

Unlike foam or reinforced concrete buildings, wooden houses have high instability. This term refers to minimal but constant shrinkage of the structure. The tree “shrinks out” not in 2-3 years, as some experts believe, but in at least 5 years. Of course, shrinkage visible to the naked eye occurs during the first 12 months, but then the home continues to decrease in volume. If you don't take into account this property and, for example, installing a plastic window in a wooden house by analogy with reinforced concrete structures can seriously pay for a miscalculation.

The shrinkage of timber and logs is from 1 to 2 cm per meter of masonry. That is, a two-story wooden house can reduce its height by 10-12 cm after 5 years. If the owners decide to install plastic windows using generally accepted technologies, they will be disappointed within a year. The entire weight of the structure will put pressure on PVC products; First, the doors will stop opening, and then the frame will crack altogether, ceasing to perform thermal insulation functions. But you don’t need to take extraordinary measures to properly install plastic windows - just install a frame in the window opening.

Design Features

The purpose of the frame (otherwise called casing) is to give the windows complete independence from the load-bearing walls of the house. The design has several undeniable advantages:

• it eliminates even the minimum vertical load on the window, since it does not allow the logs to move;
• does not interfere with the natural shrinkage of the house;
• serves to strengthen the house in the area of ​​the window opening.

There are two types of casing. In the first case, grooves are made into which wooden blocks the same dimensions as the window opening. In the second, a ridge is cut out in the latter, onto which a carriage (a log hewn on opposite sides, better known as a gable beam) with a groove is fixed.

It is advisable to install plastic windows in log house(or timber) with an assistant, since installation of the frame requires high precision, and the weight of the double-glazed window is sometimes difficult for one person to handle.

Required Tools

to install PVC windows, you will need a basic set of construction supplies, including:

• drill;
• screwdriver;
• chisel;
• building level;
• roulette;
• mallet (wooden hammer);
• self-tapping screws no more than 10 cm long (extended versions will violate the integrity of logs or beams);
• polyurethane foam;
• spacer wedges made of wood;
• spray bottle with water;
• gloves.

In addition, you will need a special adjusting hexagon for window structures. There are hundreds of videos on the topic of installing windows in wooden structures that are easy to find. However, the basic and most valuable tips are given below.

Surface preparation stage

The first thing you need to do is dismantle the old window. If its condition is not bad, it may be useful in another matter (for example, when building a country greenhouse). Window dismantling is carried out carefully so as not to damage wooden walls. After this, the opening is cleared of dust and dirt.

Measuring the parameters of a window opening must be as accurate as possible. It is advisable to record the obtained values ​​on paper. Installing a new window is simple, but just one millimeter of miscalculation can seriously warp it.

If the contour of the opening is not completely smooth, it will have to be leveled using putty or sealant. A properly prepared surface for a new PVC product is characterized by ideal geometry (right angles).

It is also necessary to maintain a reserve for shrinkage at home. This is about 6 cm in height, 2 cm in height and sides for foaming, 4 cm under the window sill.

Depending on the time of year and the current stage of construction, ordering double-glazed windows either precedes dismantling or becomes the final stage. Few people would want to install a window in a wooden house and replace it after a year or two, so some points need to be taken into account. The buyer should decide on the number of sashes, the direction of their opening, the shape, size, and color of future products. And, of course, you should order from reliable manufacturers.

Installation instructions for PVC windows

The ideal distance from the floor to the window sill will be 80-90 cm. This is slightly higher than the desk. The user must lean freely on the window sill, bending the body minimally. The further sequence of actions is given below.

1. Accurate markings are made for the side and bottom tenons (5x5 cm), after which they are cut out.
2. In previously prepared and well-dried boards (preferably inch), holes are cut out that will fill the tenons.
3. The window opening and the frame blank are treated with antifungal impregnation.
4. On the spike using construction stapler insulation is attached (jute tape, tow, etc.).
5. The casing structure is installed in the opening, starting from the window sill. Its elements are connected with self-tapping screws, and the joints are coated with sealant.

In general, the window frame is ready, all that remains is to insulate the upper landing gap. The same jute will do; the opening is caulked as tightly as possible. Now you can install a plastic window inside the opening. To do this, do the following:

1. Insert the glass unit into the opening, perfectly aligning it with the front edge. Apply a level to make sure the geometry of the sides is correct. To make work easier, first remove the sashes from the insulation units.
2. Fix the frame inside the opening using self-tapping screws, having previously drilled holes in it.
3. Fill the gaps between the glass unit and the casing with polyurethane foam.
4. Before the foam hardens, install the window sill and screw it.
5. After the foam has dried, waterproof it on the outside with acrylic sealant, sealing tape or a vapor-permeable membrane, and on the inside with vapor barrier tape.

Due to the installation of an additional structure (casing), it may seem that it is difficult to install windows in a timber or log house, but this is not so. To be confident about the durability of the structure and the reliable performance of functions by PVC products, it is better to allocate a couple of hours for additional work. The casing will allow you to avoid unnecessary expenses as the home shrinks, and will also save the plastic novelty from deformation.
