How to install plastic windows in a log cabin. How to install windows in a log house

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. The installation of energy-saving windows 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 correctly 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 must be taken into account when installing windows in wooden houses in order to avoid situations when, during shrinkage, the window structure is deformed and irrevocably damaged.

Measurement

Taking measurements in a wooden house differs from measurements in houses made of other materials. This is due to the fact that wood is capable of changing its parameters depending on environmental influences. After absorbing moisture, the wood expands.

The gap between the window frame and the opening should be of a minimum size, but sufficient, taking into account the possible expansion of the opening when wood swells. Otherwise, the skew of the window 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 examined for signs of rotting and insect damage. 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 window opening can be much larger in cleanliness.

Window system selection criteria

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

How to choose the right glass unit

The glass surface occupies the bulk of the area of ​​the window structure, therefore, 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.

The double-glazed unit consists of three glasses with a thickness of 0.4 cm, installed at a distance of 1.6 cm each. That is, 1.6 cm is the width of the air chamber.

Enhancing the ability of the glass surface to resist heat loss allows the application of protective transparent or tinted layers to the windows. Tinting can be golden, silver, bronze, bottle blue or green glass.

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. Sashes and window frames are made of metal-plastic profiles. It, like a double-glazed unit, has a 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 cameras - more energy efficiency of the structure. For example, a five-chamber profile with triple glazing is also capable of performing a soundproofing function.

Each window structure is equipped with a droplet outlet to remove accumulated moisture, as well as a special chamber in the lower part of the profile, which contains silica gel - these are small yellow granules. This substance accumulates excess condensation that can form on glass.

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. The profile can be laminated under walnut, cherry, oak or mahogany - these are the most common options.... In the case of lamination under natural species of wood, cashing and window sill are made in the same design, and the ebb is chosen in brown.

How to choose fittings and seals

Hardware is that element of the window system, which should not only have a beautiful appearance, but also be durable and reliable. The internal mechanisms of the swing-out system can withstand multiple loads. Therefore, they are made of high quality and durable material.

The service life of windows largely depends on the quality of the fittings.

The material of the seal for a plastic window must withstand temperature extremes and not deteriorate 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 reveals obvious deficiencies during visual inspection, then it must be returned.

If the customer takes out the finished windows from the manufacturer's premises on his own, then this check must be carried out at the place of manufacture of the products. As a rule, the managers of the company themselves propose to do this, so that later the customer signs in the act of completed work 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 that are indicated in the act, and for reliability check them with the dimensions in the measurement sheet. A copy of it is given to the customer along with the contract, which sometimes specifies the maximum permissible deviations. If there is a discrepancy, the act is not signed, and the product is given to the manufacturer for alteration.

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 fully assembled, so it is important to check the sash control mechanism. Then the integrity of the glass unit and the tightness 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 a subsidiary farm. When all the preparatory work has been done, you can start installing the window. How to correctly insert windows in a modern wooden house with your own hands will be discussed below.

To install windows during construction, preparation of the opening is not required

First you need to remove debris from the window box and clean it. Next, the installation of the window sill takes place. 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 posts, where it is necessary to make the corresponding indentations... It is necessary to fasten 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.

Self-tapping screws for wood are used to fix the window frame to the box. It is important to control the vertical position of the window frame. It is positioned in the center of the opening so that there is space on both sides for the assembly seam. They fix it immobility with bars or wedges.

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

When filling the assembly seams with foam, the spacers are not removed until it is completely solidified. And after the foam hardens, it is cut off and covered with a solution or plastic overlays 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 replaced in the reverse order.

Installation of a window in a log house

In order to avoid troubles that can 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 window or, in other words, a casing device.

The installation of windows in a blockhouse begins with the installation of a casing or a window, which ensures the independence of the window system from the behavior of the walls of the house. This method can also be used to install wooden windows.

To install windows in a log house, a window is first mounted

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

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 it dries.

A carriage is a vertical structure made of 150x100 mm timber, having a length that is 5 cm longer than the window size on average.

Installation of windows in frame houses

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

Window installation scheme in a frame house

Installation of windows in a modern wooden house is carried out by fastening to anchor plates, which must be purchased in advance if they were not included in the kit for the window. When installing, 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 at the 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 under the foam, placing bars under the frame, and the frame is fixed to the window. The side gaps are also foamed.

Do-it-yourself installation of windows in a wooden house should not cause difficulties while observing the technology for carrying out installation work and taking into account the specifics of a log house.

Due to their performance characteristics, PVC-material insulating glass units have gained particular popularity among the population. They are installed in buildings and structures erected of concrete, brick, wood. It is necessary to insert plastic windows in a wooden house, following certain rules.

Important nuances of installation

Starting the installation, you need to prepare the inventory that will be required: a building level and a plumb line, and also know how to insert a plastic window. It is necessary to carry out the installation of a PVC window, strictly observing the placement in the plane according to the level... This will ensure the correct operation of all elements, the doors will not spontaneously close and open.

The technology for installing a PVC window assumes its correct placement in the plane according to the level

When purchasing plastic structures, you need to buy additional special mounts for installation. The frame is fixed in the window of a wooden structure using self-tapping screws and special fasteners... Observing the technological process and correctly performing the installation of plastic windows in a wooden house, you are guaranteed to receive window blocks that will last a long time.

Fastening of the window frame is carried out using anchor plates

If you dismantle the sashes, the structure will become much easier and it will be easier to move it, however, it is still not recommended to mount metal-plastic windows in a wooden house alone. To pull out the sash, you need to remove the pins from the hinges.

How to install PVC double-glazed windows

Do-it-yourself installation of plastic windows in a wooden house is done in stages:

• preparatory measures before installation;
• installation of PVC windows;
• control-check of location in space;
• blowing out with foam.

To understand how to install plastic windows both in a wooden house and from a bar or log house, we will consider each stage in more detail.

Preparatory work

First of all, you need to take the exact dimensions by measuring the opening and order the window structure from a trusted manufacturer. To do this, most often they invite a representative of a company that manufactures plastic frames. You can take measurements yourself. After that, they are determined with the color of the structure and the completeness of the fittings necessary for the functioning of the window.

When the manufacturer delivers the product to the site, follow these steps:

• if a decision is made to replace the installed windows in the old opening, first of all, it is necessary to dismantle the structure;
• after which they clean dust, dirt and remove debris that got into the opening from dismantling;
• it is worth aligning the opening if its geometry is broken.

After completing the preparation, they insert a plastic window into a wooden house with their own hands.

Fastening the window structure to the prepared opening

We install the window sill first, it will be the base for the glass unit, so you need to put it strictly on the level (horizontally). For the strength of the fastening, cuts are made on the sides of the box approximately 8 mm deep. Adjustment is carried out using plastic plates or boards. Fastening takes place with self-tapping screws to the bottom of the box. When screwing in, it is worthwhile to put washers under the head of the screw, this will exclude damage to the surface.

The window sill is installed strictly horizontally.

The next step is to properly install the handle. The film that protects the structures should not be removed, it protects them from damage when the windows are being installed. When fastening, the handle must be placed horizontally. When all the fittings have been assembled, the installation of metal-plastic windows begins.

First you need to level the PVC frame. A frame is placed on two-centimeter bars and leveled horizontally using a water level. After that, proceed to vertical alignment.

Having received the ideal parameters at the water level, they fix the frame with self-tapping screws to the window, using mounting fasteners that were specially bought in the store. It is important not to get into the crest of the log with a self-tapping screw, where the jig is installed.

Secure the frame with self-tapping screws

After fixing the window element, we get 2 cm gaps around it for the foam.

Before using the foam, you need to hang the sashes so that after foaming the frame profile does not bend and damage the window. It is important to remember that foam can only be used when the sash is closed..

Construction control and foaming

After hanging the sashes, you need to check how the double-glazed window opens and closes. If the window, which is half open, does not close and does not move further, then the frame is considered to be correctly set and the alignment is correct. Having closed the sash, foaming is performed with foam for installation and left for full fixation for a day.

Why is a shedding done for plastic windows in a log house?

To get high-quality PVC windows in a wooden house, you need to strictly observe the installation features, that is, to mount to a special frame (base). The need for such a design is due to the peculiarities of timber buildings. Unlike a building made of stone (concrete or brick), a wooden panel house is unstable for a long period.

Shrinkage prevents deformation of the frame during shrinkage of the house

The building will sit down in the first five-year period after its construction. In this case, the walls dry up to 6 cm. This important nuance must be taken into account when installing a plastic window in a frame house. It is clear that it is impossible to simply insert a plastic window into a wooden house; it is necessary to create a structure for the opening, which has the name of a shedding, they also say - a window. Its direct purpose is to prevent the shrinkage of the walls from affecting the frame, therefore the window:

• strengthens the opening;
• carries a load;
• prevents the effect of shrinkage.

Okosyachka looks like a box made of thick boards. The structure is fastened in the side post to the groove, and fasteners are not used. Above the window there is a gap for shrinkage compensation for a wooden house. There are several options for installing it:

• a groove is cut in the log, where the bar is laid. Self-tapping screws are screwed into the last element of the embedded beam;
• a groove is cut out in the racks on the sides of the structure, a spike is cut out from the end of the log in the opening;
• a groove is made at the end of the logs, a spike is located on the side racks of the box.

Casing options

To get a high-quality design, you need to follow the technology of installing plastic windows in a wooden house. To begin with, they cover the crests of the logs with insulation and fasten it with staples or small carnations. This stage is necessary to insulate the house and eliminate squeaks. Then the lower crossbeam of the casing is mounted, and the carriages (side posts of the scissors) are stuffed onto the ridges, the upper bulkhead is laid in the upper groove of the posts. After collecting the boxes, they are carefully connected with self-tapping screws, it is important that they do not fall into the logs.

The slots that are visible in the opening after installing the casing must be filled with tow or insulation. Then there is a standard installation of plastic windows in a frame house or log house.

The slots are sealed with insulation or tow

The expansion gap is filled with flat planks, pre-wrapped with tow. When the walls shrink, they are gradually knocked out. To do this, remove the upper platband and, knocking out the plank, put it back.

The final stage in the glazing of a wooden structure

Finishing after installing PVC windows in a log house is done in the same way as wooden ones, that is, after installing the frame structure and insulation, they put platbands made of wood. When ordering PVC windows in a wooden structure, you should take a closer look at the option for the texture of the wood, this will allow them to look harmoniously against the background of a felled structure.

Many manufacturers of PVC structures offer not only the classic white version of the frame colors. You can order any shade that the customer wishes. Colored plastic frames will cost a little more, but will be more suitable for a home made from natural materials.

When ordering, it is important to correctly measure the opening and not be mistaken in the width of the window sill. Self-installation of a PVC window in a wooden house with knowledge of all the nuances is not such a difficult process. You can do it yourself, without resorting to the help of expensive installers.

Wooden houses, baths, saunas and summer cottages have an important advantage - they are completely environmentally friendly, since they are made of natural materials. A wooden blockhouse is "alive", it "breathes", settles down and grows old, that is, it lives its own life. A house made of natural wood provides air circulation, simultaneously purifies it and imparts healing properties, thanks to phytoncides and resinous substances of natural pine wood. The same features of buildings made of lightly processed wood create some difficulties. For example, when it is required to install windows in a log house and doorways, as well as when finishing sagging walls, but subject to the installation technology, all these problems can be solved.

Which windows are suitable for wooden walls

The walls of solid wood houses tend to be in some motion. This is influenced by the time of the year, seasonal changes, humidity of the air and the environment - the blockhouse swells or dries up, sitting down. Some of the usual standards for installing windows and doors are acceptable for a log house, so a different frame recess design is needed here, known as a cage. It makes it possible to minimize the movement of wooden walls of houses, baths and other residential buildings made of logs.

However, not everything is so difficult, since the main shrinkage occurs during the first 3 years - under its own weight, the space between the logs is compacted and the wood naturally dries out. Sometimes, during this time, the frame sinks by 10-15 cm, and the window and door openings decrease accordingly. Therefore, it is natural that for a new building made of natural wood, wooden windows in a log house are more suitable, and for older houses - plastic ones, then they will be less susceptible to excessive pressure and deformation.

If the construction of a house has been going on for more than one year, stage by stage, then even unprepared "live" wood will sit down during this time, and the installation of windows in a frame made of wood will not be problematic. As a last resort, you can install temporary frames with a film, preventing the penetration of precipitation into the window opening. And after a while, window frames with double-glazed windows can be put into a wooden blockhouse to protect against adverse weather factors. It can be frames made of specially prepared dry wood, and plastic, familiar to the townspeople.

Modern plastic windows laminated under natural wood will organically fit into the design of the log house, increasing the thermal insulation of the house. The experience of Finnish installers shows that a plastic window in a log house or double wooden frames can be easily inserted into a window, and different materials for window frames can be combined.

What is important to know about installation technology

Today, prestigious two-story houses of various types are made from timber. They are built in eco-style according to the traditions of their ancestors and according to the projects of modern architects and designers. Increasingly, they began to offer wooden houses and saunas of the Finnish type, and stylization of country houses like a Russian tower is also in vogue. No less interesting are the large Scandinavian-style manors made of wood and glass. It doesn't matter if the building will be pompous or a small cottage made of wood with your own hands - the technology for installing wooden windows in a log house is about the same.

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

The holding time is required for the shrinkage of the frame and the final formation of the wooden walls, and after about a year, the frame will acquire close to the maximum shrinkage parameters. However, it is impossible to accurately name the technical characteristics of shrinkage (in percentage or in millimeters), since everything depends on the type of wood and the degree of its moisture content.

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

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

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

3. Often, special (cranial) strips are used, inserted into grooves, which move freely in the ends of the window opening. This counteracts shrinkage seizure without crevice formation. Thanks to the design, the skull slats are able to slide in the grooves, so the window will not experience pressure when shrinking. The difference between the method is in attaching the casing to the cranial bar, and not directly into the opening.

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

Basic conditions for the use of casing

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

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

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

4. Simplified boarding can be made of boards with a thinner thickness of about 20 mm, where the forming slopes will be attached, and the lower board forms the window sill.

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

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

7. Competent use of the casing installation technology allows to counteract the depressurization of the window.

8. Fastening of external platbands allows the use of synthetic seals, including rubber, to exclude the penetration of moisture into the window space.

9. If you have any difficulties and questions - how to insert windows into a blockhouse, it is recommended to contact a specialist.

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

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

2. Installation of windows or doors in a wooden frame is a technologically simple process, and specialists do not have any problems. However, difficulties and problems with a non-professional approach arise much later, when the windows in the bathhouse or in the house begin to warp due to the pressure during the natural drying of wood. That is, it is much worse when problems loom during the operation of the building.

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

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

Instructions for processing a window opening

To complete the work, you will need a chain saw, nails, hairpins, a bar, an edged board, a square, a plumb line and polyurethane foam.

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

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

3. We make holes in the uncut crowns at the corners of the planned opening, and in the same way in the fastening boards.

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

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

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

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

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

10. To check right angles, use a square that can be formed before the block is finally secured.

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

Step-by-step execution of window installation

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

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

This is a casing box with grooves, a shrinkage gap with a seal, an outer and inner casing, a spike with a seal, a window with an ebb, a lower inter-row seal.

Okosyachka is done after the formation of the opening:

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

The process of installing plastic windows in a log house

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

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

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

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

There are two types of bobcats:

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

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

Next, we assemble a jamb from a 150x40 board, as described above, respectively, cut out the grooves in it, which are put on the comb - this is the upper part of the opening where we put the PVC window. Be sure to overlay the planks with tow (in rolls) and fix the carriages, and fix the upper plank of the jigs with self-tapping screws to the carriage.

After the right angles, vertical and horizontal lines in the openings have been verified, the window has been drawn up, they proceed to the installation of plastic windows. Pay attention to the quality of fastening and tightness so as not to violate the thermal insulation of the windows in the frame. Do all the steps according to the instructions attached to the PVC windows. When buying plastic windows, pay attention to the fasteners that are mounted at the end. The frame is leveled and mounted with attachments to the window, do not forget about the place for the foam under the windowsill. It remains to hang the sash and put the cashing.

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

Every reader of the site knows that no matter what material the windows are made of, they help to keep warm in the house and emphasize the individuality of any home. Therefore, the installation process should be treated with special attention. After all, even the most expensive and energy efficient window structure loses all its advantages if it is installed incorrectly. In this article, our experts tell you how to install windows in a wooden house, frame and stone.

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

From our article you will learn:

• Where does the preparation for the installation of a window structure begin;
• What are the stages of work preceding the installation process;
• What features you should know about in order to install windows in wooden, frame and stone houses;
• How to install a wooden window with your own hands - how much its installation differs from the installation of a plastic window;
• How the mounting joints are protected;
• How to control the installation process.

Preliminary preparation

Despite the seeming simplicity, installing windows at home is a process that requires a serious and responsible approach. After all, the quality of installation directly affects the level of comfort in the house. This is where the process begins:

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

First of all, you need to carefully prepare: familiarize yourself with the instructions and existing installation standards, acquire the right tools.

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

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

These include:

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

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

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

Do-it-yourself installation of wooden windows in a frame house.

We install wooden windows with our own hands

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

Anatoly Gavrysh:

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

Do-it-yourself installation of a wooden window should be carried out more carefully. And in each case, an individual approach is required.

Alexander KorpachevHead of the installation department of the company "Business-M"

Even windows in the same house can have their own characteristics. Therefore, in the work it is necessary to adhere to the recommendations of GOST, namely:

• Mounting window seams - with vapor-permeable self-expanding tapes;
• Specifications, GOST R 52749-2007;
• Assembly seams of nodes and junctions of window blocks to wall openings;
• General specifications, GOST 30971-2002;
• Window blocks are made of polyvinyl chloride (PVC) profiles. GOST 30674-99.

In general terms, installation consists of the following steps:

• Opening preparation;
• Window preparation;
• Installation;
• Finishing work;
• Finishing finish.

I would like to dispel illusions about the ease of installation of both plastic and. To carry it out on your own, you definitely need certain skills and special equipment, since correct installation is of decisive importance in how well and for how long new window structures will last.

In more detail, the installation of both plastic and wooden windows is done as follows:

1. Window openings are cleaned of dust and dirt.

2. Windows are installed in the opening and wedged with small plastic or wooden corners strictly according to the level.

The corners are necessary to form a gap (margin) between the frame and the opening. Along the perimeter - between the window and the opening, it is recommended to lay a technological gap for foaming with a width of 20 mm. In the lower part of the window - under the window sill, it is recommended to lay a stock of 35 mm.

3. The structure is fixed.

Fixation is carried out using dowels or special mounting toothed plates. If through fastening of the window to self-tapping screws is made, then before that, holes for the anchor are outlined and drilled in the opening. The number of attachment points depends on the size of the window and on average ranges from 40 to 70 cm. From the corners of the frame, an indent of 12-15 cm must be laid.

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

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

5. The foam is covered with steam and waterproof tapes.

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

6. On the outside, additional elements are installed in their place - cover strips and platbands (if installation takes place in wooden houses).

7. The fittings are being adjusted.

Features of installing windows in a wooden, frame and stone house

Anton Karyavkin

It is most difficult to install windows in buildings made of rounded timber. This is due to a change in the construction of wooden houses from manufacturer to manufacturer.

If developers use different types of wood when installing windows in a wooden house, it is almost impossible to predict the behavior of the material - every time you have to study everything from scratch. The deformation of the logs in such buildings can be quite large: from 8 to 15 cm. The house shrinks, so not a single window in such conditions can maintain its performance for a long time.

Correct windows in a wooden house.

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

Anton Karyavkin

The most responsible developers start cutting an opening in the timber walls only a year or even two after the construction of the house. During this time, it is possible to track all deformations, taking into account the characteristics of the material and the climatic characteristics of the region.

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

Alexander Korpachev

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

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

Anton Karyavkin

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

Despite the fact that the box quite effectively absorbs the deformations of the logs, the assembly joints in this type of building still remain mobile. It is important here to choose the right polyurethane foam - it should not collapse when the walls shrink. You can find this correct foam on the market, but it is relatively expensive. Therefore, experts often replace it with other materials, mainly of plant origin (tow). Of course, the tape and coating materials required to protect the assembly joints must also have a high deformation resistance class.

Glued laminated timber shrinks significantly less than solid logs. As a result, laminated veneer lumber deforms less than a regular log.

But it is still difficult to install windows in a wooden house with your own hands.

How to lay a window in a frame house

Wooden windows can also be installed in a frame house, but plastic windows are most often used. The control of the installation of any windows at all stages should be checked using a level or plumb line, and the horizontal and vertical deviation should not exceed 1.5 mm per one meter.

Anton Karyavkin

The process of installing windows in a frame house is much easier than in a wooden one. You will still have to deal with deformations of the window opening, but they are no longer so significant.

It is better to use anchor plates as fasteners. It is not recommended to install on construction screws: they fix the box, and the deformation of the tree, in turn, can cause damage to the windows.

How to install a window in a frame house

It is important to remember that when installing a plastic window in a frame from a room, it must be wrapped in a window opening. This is necessary in order to connect the vapor barrier of the window to the vapor barrier of the room.

Bricks of various types, concrete, aerated concrete blocks are standard building materials. The technique in stone houses has been worked out over the years. Fastening is carried out using dowels and construction screws, it is also allowed to use anchor plates.

Anton Karyavkin

In some cases, the installation technology may be influenced by design decisions that require taking into account the linear dimensions of structures and the wind load in the region.

Protection of assembly joints and stages of assembly work control

Regardless of the material of the walls, it is necessary to ensure the protection of the polyurethane foam from ultraviolet radiation and atmospheric moisture. Otherwise, it will become loose and lose its properties over time. To protect it, special insulating tapes and sealants are used. The latter are good in that they allow you to close any cracks and irregularities, in contrast to the mounting tape, which requires a perfectly flat surface without dust.

A window opening in a wooden house has always been one of the most difficult building blocks. With the advent of PVC windows, an extensive list of new restrictions and requirements related to the universal design of metal-plastic profiles has been added to the problems caused by shrinkage processes. In this connection, the installation of plastic windows in a wooden house with your own hands should be done only after a thorough study of all the features of this technology.

We emphasize right away that the principle of fastening PVC windows is, in principle, different from the method of installing classic wooden frames, therefore, even experienced craftsmen who have not had any experience in this area of ​​construction work, it is advisable to study the relevant documentation and technological advice from window manufacturers.

You will find general information on the technology for installing plastic windows in our article, and today we will give you step-by-step instructions for self-installation.

When preparing for self-installation of a plastic window, you should pay special attention to the preparation of tools and materials. Considering that in most cases, the installation of windows in wooden houses is carried out in the field mode (summer cottage, country house, etc.), the absence of one specific key or device can create considerable problems.

Consider the main groups of tools that are required to properly install the window structure.

Mechanics

From a mechanical point of view, plastic windows are far from a standard design, so the usual set of a home master will clearly not be enough.

Below is a list of mechanical tools required to work effectively with PVC profiles:

• iron and rubber hammer (elastic striker is used to position the frame);
• universal screwdriver;
• set of hex keys;
• handle for removing the pins (with a hexagonal tip);
• electric drill;
• drills for concrete and metal (diameters from 3 to 10 mm);
• mounting wedges and gaskets;
• universal adjusting key;
• measuring kit (tape measure, square, building level, plumb line);
• a device for capturing double-glazed windows ("glass jacks").

Please note that a conventional hacksaw may not be enough for cutting expansion profiles, since some types of accessories can be reinforced with metal. Of course, you can cut such a profile with a hand saw, but you will have to spend much more time on each detail.

Considering the above, it is useful to supplement the above list with a mechanized saw version (jigsaw or circular saw), as well as fixation devices (clamps).

It is advisable to take a clamp with a wide grip, since they may be needed not only for fixing materials during cutting, but also for attaching expansion profiles.

Sealing

An integral part of the assembly technology for metal-plastic windows is sealing using sealing tapes and polymerized substances.

When installing PVC profiles with your own hands, you can use the sprayers supplied with the foam cylinders, but for professional work it is advisable to purchase a separate device that will significantly reduce the cost of consumables.

Separately, we emphasize that in addition to polyurethane foam, when installing PVC windows, silicone is often used, which is extremely difficult to squeeze out of the tube without a special "gun".

Waterproofing

Any polymer sealant - and polyurethane foam is no exception - in case of constant contact with outside air and moisture, it quickly collapses. To slow down this process, the internal and external surfaces of the installation gaps must be protected with waterproofing (installed on the internal surfaces, this protection is called "vapor barrier").

This can be done both with the help of a special tape, and through the application of special pastes (putties).

Depending on which type of waterproofing is preferred, the basic list of tools must be supplemented with scissors or a set of spatulas.

Preparing for installation

After the PVC window is purchased and delivered, it is imperative to check the completeness and conformity of the actual dimensions to the parameters specified in the order.

Before starting a technical description of work on self-installation of windows, we list the main terms used to designate elements of their construction:

• frame (power base of the window);
• sash (movable part of the window);
• double-glazed window (1-2-3 chamber set of glasses, combined into a single block);
• impost (internal partitions of the frame);
• glazing bead (latching strips necessary for fixing glass units in the frame or sashes);
• fittings (control and regulating elements of the window);
• slope (decorative panel covering the end of the log house or the inner plane of the casing);
• windowsill;
• addition (expanding profile used to adjust the geometric dimensions of the window).

Examination

As practice shows, during transportation, window handles and other auxiliary fittings are often lost.

If the order included a mosquito net, you must check the availability of fasteners for its installation.

In addition to the completeness, the conformity of the dimensions of the window and the casing is checked. The main test criterion is simple - the installation gap should be no more than 2 cm (but no less than 5 mm!). It should be borne in mind that when comparing linear dimensions, the above tolerances are multiplied by two. That is, if the inner width of the casing is, for example, 200 cm, then the total width of the frame should be no more than 200-2 * 2 = 196 cm.

In those cases when the window was bought with the expectation of building up by additions, measurements are made taking into account the mutual overlap of the locks.

Next, you need to select the fastening pins, the length of which should be such that, when fully screwed in, they do not pierce through the casing.

This requirement is relevant only for those cases when the installation of the window is carried out with the drilling of the profile. However, it should be remembered that this installation method is a spare and is used only in those cases when the window is mounted in a window, consisting only of a foundation bar.

The main way of fixing PVC windows in the opening is installation on anchor plates, the purchase of which should also be included in the list of preparatory work.

Disassembly and preparation for installation

The next stage of preparation for installation is disassembly of the factory delivery set. Despite the fact that the installation of the window can be carried out without dismantling the double-glazed windows, we recommend using the option with complete disassembly, since it is much easier to place and center a light frame than a massive and inconvenient for manipulation window block.

Below is a step-by-step guide to the disassembly and preparation process:

• remove the packaging and the protective tape (you can leave the tape on the inner surfaces, but if you leave it on the outside, then after 1-2 months it will firmly "stick" to the frame);
• remove the double-glazed windows. To do this, it is necessary to remove the glazing beads from the latches. You should start from the bottom;
• dismantle the frames, for which you will need to remove the locking pins (a special key mentioned in the previous section is intended for this operation);
• dismantle the auxiliary fittings, otherwise during installation it may be lost or damaged (plugs for drainage holes, covers for hinges, etc.).
• if the window is installed in the reverse quarter - stick the PSUL sealing tape on the outer perimeter of the frame;
• drill holes for pins or mount anchor plates (depending on the installation method).

We would like to highlight the following nuances:

• when removing the double-glazed windows, the initial position of the left and right glazing beads should be noted;
• the lower edge of the double-glazed windows must be installed on special gaskets - it is necessary to mark their position;
• gripping glass panels is best done using a special tool (it is also indicated in the above list of tools);
• The removed insulating glass units should be handled with extreme care so as not to damage the edges (and also to avoid vertical storage).

Installation methods

There are two different ways to install PVC windows with your own hands: with and without disassembly of the window block.

This difference is due to two factors: the window fastening scheme and the weight of the structure.

The first option is more versatile and allows window installation in any way.

The second method is used only in cases where the fixation of the window block in the opening is carried out using anchor plates. It is used for the installation of blind windows, or to massively install windows of a standard format in a T-shaped casing.

It is obvious that the installation of a window without disassembly is an order of magnitude faster than with disassembly. However, in view of the fact that most assembled metal-plastic window blocks have significant weight, only the first option is recommended for self-installation.

Installation of plastic windows

In order to correctly install the window yourself, you should clearly understand the main rule of installation operations of this type: the efficiency of the window depends not only on the quality of the glass unit, but also on the correct assembly of the entire structure of the window unit, which includes several auxiliary subsystems.

In this case, "auxiliary subsystems" mean:

• waterproofing;
• additional seals;
• slopes;
• ebb tides;
• platbands.

Particular attention should be paid to the position and protection of the sealants. The figure on the right shows the basic layout of additional seals.

Please note that the seal around the outer perimeter of the window is only installed in the reverse quarter installation. If the window is mounted in a conventional T-shaped casing (which is the most common case), then the slopes play the role of such a sealant.

Now we will consider step by step how to properly mount PVC windows in wooden houses.

Removing old windows

When disassembling windows in houses made of timber and logs, special attention should be paid to the safety of the window, since making a new one will not be cheap.

In cases where the previous installation was carried out correctly, and the frames were fastened using self-tapping screws, the dismantling sequence consists of only three operations: removing the fasteners, removing the window block and stripping the casing from the remaining foam.

Some problems can arise if the old window was nailed down, which may require an additional tool - a nail pusher - to remove it.

It is important to take into account that, before installing a new window, it is imperative to revise the casing frame. Namely: it is necessary to check for cracks, chips, as well as the absence of signs of decay or damage by woodworm. If any of the above factors is found, the window should be replaced with a new one.

Note that regarding the replacement of a box in the network, you can find many contradictory recommendations, among which there are some that claim that when repairing old houses, windows with a metal-plastic frame can be installed without a box. We consider this approach to be incorrect, since even an old log house with seasonal changes in humidity can create a displacement sufficient to jam or even destroy a window.

Of all types of wooden buildings, only in a frame house you can not install a sliding casing, but even in this case, the installation of a window is made in a finished wooden frame.

Unlike stone houses, in wooden buildings there is rarely a need for "patching" repair of the installation site, since the cage almost always provides an even rectangular opening for fixing a new window.

The only exception may be the situation when it is necessary to insert a window whose dimensions are smaller than the previous one (the need for such a replacement often arises when repairing a bath). In this case, the preparation of the inner opening consists in increasing the thickness of the casing strips.

Frame fitting

The most common mistake made when installing a Euro-window with your own hands is incorrectly taken original dimensions.

Therefore, before starting to fix the window, you need to make sure that it really matches the installation opening.

Fitting the frame is simple - the supports 1.5-2 cm thick are placed on the lower casing strip. The frame is installed on them, after which a visual assessment of the remaining gaps is performed.

If in any part of the window they exceed 2.5 cm, you need to think about correcting the geometric dimensions of the frame with the help of extensions.

Separately, we note one nuance - if the size of the gap between the frame and the casing is more than 2 cm, but less than the minimum thickness of the available expander, then there is a temptation to blow it out with foam without any size correction. Many do so, after which they cannot understand why an expensive PVC window is so cold.

It is important to remember: polyurethane foam is not a full-fledged heat insulator, and in no case can act as a substitute for a window profile.

Window frame installation

After the correspondence between the dimensions of the frame and the opening has been established, you can proceed to the main operations.

Let's list them in stages:

1. Initial positioning. It is carried out in the same way as the fitting: the frame is installed on the centering pegs, after which it is necessary to achieve a uniform thickness of the installation gap around the entire perimeter of the frame.
2. Spatial alignment. For vertical positioning, it is better to use a plumb line, horizontal - a building level. Work fixation is performed using lateral and upper spacers.
3. After the accuracy of the installation has been confirmed, fix the vertical points first, and only after additional verification - the lateral ones. As mentioned above, the fasteners can be long screws or anchor plates.
4. Immediately after completing the fastening fixation, we recommend installing the ebb, since after assembling the window, access to the corresponding mounting positions will be difficult (this moment is especially relevant for windows located on the second floor).
5. Installation of window sashes at workplaces.
6. Installation of double-glazed windows. Please note that the glass panel must not be placed directly on the plastic of the sash (during dismantling, special gaskets must be retained).
7. Fixing double-glazed windows with glazing beads (in reverse order).
8. Close the doors and check the positioning again.
9. We carry out the installation of fittings.

Once again, we remind you what you need to pay special attention to at the stage of installing the frame:

• the position of the transverse line of the window - for wooden houses, it should run exactly in the center of the frame;
• the length of the fastening pins (if the through-fixing method is used) should not exceed the total thickness of the frame and casing boards;
• to secure the outer "tails" of the anchor plates, use fasteners less than the thickness of the casing plates.

Foaming the window

The next step is to fill the installation gap with polyurethane foam. Despite the apparent simplicity, this stage has several technical features at once:

1. The polyurethane foam expands during polymerization and the force created by this is capable of deforming the metal-plastic profile. Therefore, blowing out should only be done on a fully assembled and closed window.
2. If you intend to use the tape version of waterproofing, it is much more convenient to immediately veneer the installation gap from the outside of the frame.
3. To simplify the installation of the vapor barrier, we recommend cutting the tape and fixing it to the window frame.

Blowing is done from the inside, after which the seam is immediately sealed with pre-installed pieces of vapor barrier tape.

Possible problems with incorrect installation of windows

Avoiding lengthy discussions on the topic "which is better to install windows so that the savings are truly economical", we will formulate a simple rule: any, even the most expensive window, will not provide the declared characteristics if it is installed incorrectly.

Therefore, in addition to strictly following the above recommendations, the following mistakes should be avoided:

• incorrect position of the window along the thickness of the frame. The consequence of the error is freezing and condensation. For classic wooden houses, the windows are installed in the centerline. In cases where the house is lined with bricks or lined with thermal insulation, we recommend contacting specialists to calculate the position of the window;
• lack of seasonal adjustment. The consequence of the error is a violation of the air exchange standards. In those windows, where possible, the adjustment is carried out using the slots set to the desired position.
