Sliding frame for a window in a wooden house. Installation of windows in the log house of the bath using casing boxes. Installing a window frame in a wooden house in the video

A special box made of wood, popularly and by specialists called “pigtail” and “casing”, consists of sides, top, window sill or threshold. Their installation is carried out in a wooden house in openings in which doors and windows should be located.

The main purpose of using casing is to preserve doors and windows during the period of inevitable shrinkage in a wooden house. This is one of distinguishing features architecture, during which the building is protected from the risk of displacement of logs. Do not give up on the window openings, as this is fraught with violations in the optimal functioning of windows and doors.

Casing in a wooden house: features

The width of each constituent element of the pigtail should not exceed 26 cm. Of course, it can be greater than this indicator, but then cracks will begin to appear throughout the structure. The frame for windows and doors is made of wood with a moisture content of at least 10%. If it is less, then internal cracks may appear. During the manufacture of pigtails, care must be taken.

Installation of casing in a wooden house takes place without the use of nails and other elements. For the most comfortable sealing, it is required to lay heat-insulating material in the space between the frame and the log.

Types of pigtails

There are several types of pigtails in a wooden house:

1. Array. Each piece is made by processing solid wood, while preserving the texture of wood. In the photo you can see what this option looks like;
2. Adhesive. Each element is made from a typesetting board. The microstud is attached to each of the four sides. All knots are completely cut out;
3. Combined. This option is the most common. For the production of the top and racks, an array of pine is used. The window sill is made of typesetting glue board. After installation, such a pigtail will need to be coated with a protective varnish.

Casing is made individually for each window or door. It can be made:

1. Window casing with a selection under the window. This option is used if the house will not be interior decoration;
2. No sampling under the window. This solution will be used when both interior and exterior decoration is planned. If you look at the photo, you can see that the pigtail looks better without sampling under the window.

Do-it-yourself window tinting - tools

Over time, the construction of a house from a bar shrinks heavily, as the tree shrinks. It twists and begins to bend, as a result of which doors and windows can be damaged. To avoid this, you need to do a pigtail. Casing in a wooden house is the secret of its durability. In addition, along with it, the structure has an attractive appearance.

The manufacture and arrangement of the pigtail occurs using the following tools:

1. Chainsaw;
2. grinding machine;
3. Drill;
4. Screwdriver;
5. Jigsaw.

You also need to prepare some consumables, these are bits, a measuring tool, protective equipment - goggles with a respirator.

Anchor for a normal window

A simple do-it-yourself pigtail, which is included in the construction of a house from profiled timber and any other type, includes the following steps:

• In the logs adjacent to the opening, carve grooves. A pre-prepared bar will be inserted into them;
• Bar - one of the sides of the casing. The lower beam is placed first, the purpose of which is to prevent the displacement of the sidewalls;
• Under it, you need to lay an interventional sealant in advance, for example, linen fabric. In the photo you can see how it looks;
• Next comes the installation of vertical bars. It is also required to lay a sealant in the grooves for them;
• The last to install the upper casing beam;
• Above the pigtail, a shrinkage gap is made without fail. An interventional sealant must also be placed in it.

Some use polyurethane foam as a material for sealing. This is undesirable, as it holds the logs together and prevents them from shrinking naturally. The use of polyurethane foam in the manufacture of pigtails makes the whole process useless.

Pivot for plastic window

A slightly different method is the manufacture of do-it-yourself casing for plastic windows.

1. It is necessary to prepare the window opening in advance. The opening must be made at least 13 cm larger than the size of the window frame;
2. The gap must be calculated taking into account the dimensions of the seams and the percentage of possible shrinkage;
3. The next step is sawing the ridge in the already finished window opening. The crest is needed as a base for the gun carriage. In the inner part of the carriage there is a groove along which the logs will shrink;
4. For the manufacture of a gun carriage, it is required to prepare a beam with a section of 100x150, make a groove in the middle. Put a comb on this groove. The carriage size should be 5 cm larger than the window. Also, the width and depth of the carriage must be equal to 5 cm. Its manufacture takes place in this way: all parameters are clearly marked, then the element is sawn with a chainsaw;
5. The upper side of the casing must be made of a board with a section of 40x150 mm. From the sides of this board, it is required to cut grooves for the ridge. After that, the upper crossbar is placed on the ridge;
6. After installing the sides, the crossbar must be fixed with self-tapping screws. We must not forget that the screws should not fall into the comb. Otherwise, rigid adhesion of the structure will occur, the casing will not be able to function optimally;
7. After completing the assembly of the casing, each gap must be insulated using jute or flax fiber. Ridges and grooves need to be caulked.

To better understand the manufactured window pigtails, you can watch the video of professionals.

Door frame

Making a door frame with your own hands is more difficult than planting windows. This is due to the large size of the work and with the change in the entire technology of the installation, the drawings of the process are also changing. One of the options for installing a door frame:

1. Using a plumb line and level, it is required to make measurements, mark the location of the opening;
2. Using a saw, cut an opening according to the specified parameters. When choosing the size of the doorway, it should be borne in mind that the door frame also takes up a lot of space;
3. On each of the sides, using a chainsaw, it is required to cut grooves so that a symmetrical spike forms. It will be necessary to connect the opening and casing;
4. In the jambs, you need to create spikes corresponding to the grooves. You can see how this is done in the photo and video;
5. Jambs start with their spikes along with grooves, after which they are bursting with crossbars from the bottom side, after that from the upper side of the opening. A gap of up to 10 cm should remain above the upper part of the pigtail;
6. Rigid fastening of the casing to the walls is excluded. It is necessary to install the pigtail so that it does not have any effect on the natural shrinkage of the wooden house;
7. All joints and gaps must be sealed with linen fiber. We must not forget about the upper gap, the seal of which should be compressed without problems;
8. After that, it is required to close all the cracks and voids using platbands. Then the pigtail will look like in the photo;
9. And the last, but important step, is the treatment of the entire surface with an antiseptic.

To supplement this instruction, a professional video can. After reading and viewing it, it will be possible to start making do-it-yourself casing for doors and windows.

It will never be too late

Even if the log house has stood for more than two years without a pigtail and has already shrunk, the casing can still be installed. It is guaranteed to retain its original shape, and will also make the wall stronger and more stable. In addition, the casing can serve as an external decoration. Building a house from glued beams involves the use of glued material for casing.

Today, a whole industry is engaged in the manufacture of casings, so choosing the pigtail that is suitable for your interior and window shape is not difficult at all. Casing can be made for any opening parameters, but it should be borne in mind that unusual pigtails carry some disadvantages that can be dealt with.

Okosyachka: cost and rates

Manufacturing costs can vary greatly, as the cost of a pigtail depends on a large number of factors. This is influenced by the quality of the wood, the types of casing, its shape, the presence of decorative details, the parameters of the opening, as well as the material into which the installation will take place. Of course, the final cost will be affected by quantitative indicators, how many pieces or meters.

The type of casing will have a big impact on the cost. Among themselves, all types differ in technical features:

• "In a mortgage bar" - is considered the most economical option. Made from edged board. A groove is cut out on the inner wall, into which a bar with a square section is laid. Due to the quick assembly and attractive cost, this option is popular;
• "In the spike" - a more expensive option, differs from the previous variety in higher quality. This bar is produced with a cross section, in shape equal to the letter "T";
• "To the deck" - has almost the same cost as the previous version. To do this, a spike is cut out in the sidewalls of the opening, on which a deck is put on, which has the shape of the letter “P”.

Prices for the manufacture of obkosyachki by different companies:

The casing (pigtail) is a wooden box along the perimeter of the window opening in wooden houses. Such a clever device will keep the window intact when the structure shrinks (and it will definitely happen).

In this article, you will get to know braid options and prices.

How does a pigtail work? Types of casing by installation method

Any pigtail window openings (for plastic or wooden windows) consists of three parts: top, sidewalls and threshold - window sill (see photo). A window profile is installed on them.

The main feature of the casing is, which is mounted in the opening with its groove method not close (a heater is placed between the box and the opening). So when the house shrinks, it easily maneuvers, saving the window from being pinched in the opening.

Pigtail dimensions strictly defined. If the house is made of a four-rolled beam, then in the section the vertical guides are 15 (20) x 10 cm, and the top one is 15 (20) x 5 cm. The lower pigtail is a window sill.

The most correct pigtail in a log house is 25-30 cm wide. And 5-6 cm thick.

According to the installation method, there are the following types of pigtails in a wooden house:

AT this case on the vertical end sides of the opening, one groove of 5x5 cm is cut out. And bars of the same size are installed there. Then the casing box is screwed to the bars and the bottom of the opening. And the mobile structure is ready! (See pigtail drawings).

It is possible to install only a bar - without casing. In this case, the profile is screwed directly to the bar. However, remember that this option is not suitable for plastic windows - only for wooden ones.

This is when the mortgage beam and the sidewall form a single whole. Everything else is the same as in the previous case. Namely: at the end of the opening there is a groove 5x5 cm, in which the side of the box is installed with a spike.

How to make and assemble a pigtail, you can read in another article:

On the site you can find out. See the list of tools and several ways to mount a window.

An article for those who choose the type of windows and glazing for their "summer residence" or year-round "refuge" outside the city.

In another way, they call it a “pigtail in a groove”. Such a pigtail scheme is as follows: a spike or ridge is cut out at the end of the log house - a guide for the casing. And on the sides they make grooves for it a little larger. The decks are connected to the threshold using studs or dowels - large wooden nails. The apex is attached to the side posts with self-tapping screws.

It looks like a pigtail in a thorn. But this is a ready-made version that performs 2 functions of a pigtail and a slope, because. on the outside, it has a quarter (protrusion) for installing a window. Does not need additional finishing. Therefore, it is also called a finishing or finished pigtail.

What are casing boxes made of?

As a material for the pigtail, pine, larch, etc. are used. In general, which is cheaper. But it can be more expensive. Wood is always processed in different ways:

1. Take whole wood with a moisture content of 10-12%. This type of pigtail is called "from solid pine".

Glued casing is better than whole casing, because here all unnecessary elements are cut out of wood: knots, etc.

2. They make a glued pigtail from the cut material, from which knots, resin pockets are removed - they are completely useless there. The moisture content of such wood is significantly lower - 7-9%.

3. Individual elements are connected with the help of microstuds and high-strength glue. So you don't have to worry about the safety of the structure.

4. They combine the top and sides from the array with typesetting-adhesive window sill.

The first option is suitable if you are going to additionally install slopes. And the second - if they go separately.

Information about retail and prices for pigtail

On the domestic market there is a rough and finished pigtail. You can buy a sash for windows in every first company that sells wooden windows. And also in firms for the processing of wood and the manufacture of products from it.

What is the price of casing or okosyachki? Pleasure is not cheap. But a personal wooden house, too, so…

We looked at prices for different types of pigtails in several companies. And the averages were placed in the table.

The cost of a pigtail in a wooden house

Type of pigtail	Price per r.m. (rub.)
Rough casing boxes
Solid pine	400-1000 - depending on the technology
Finishing casing boxes
From solid pine	600-1200
Glued pine	1000-1200
Glued larch	1200-1500

Prices are for a pigtail 20 cm wide, without additional processing and painting.

The technology for installing a plastic PVC window in a wooden house differs from the traditional one. Compared to brick or concrete houses, wooden houses are more susceptible to shrinkage. Therefore, the installation of a plastic window differs in the preparation of the opening, and even in the sequence of operations.

Features of shrinkage of a wooden house

All houses settle, exerting pressure on the ground - stone houses are larger, wooden houses are smaller. The correct selection of the type of foundation, taking into account the characteristics of the soil (including its heterogeneity, the depth of groundwater, the nature of the perched water, etc.), allows minimizing the effect of settlement on the geometry of the structure.

House shrinkage is a consequence of changes in the size of the building materials themselves.

It manifests itself especially strongly in the first years of operation of wooden houses built from logs or timber of natural moisture. Therefore, the installation of windows in a new house is carried out when it has passed the “active phase” of shrinkage, which is from 6 months to a year (depending on the type of wood, region and cutting season, type of material, etc.). But even then the shrinkage continues, but already much less.

Minimum shrinkage for glued beams, a little more for chamber-drying beams. In new houses made of such materials, windows can be installed immediately, after the construction of the walls and the arrangement of the roof.

But in any case, when installing windows, these features of wooden houses must be taken into account.

The role of the pigtail in a wooden house

The peculiarity of a tree is that it reacts unevenly to changes in its own humidity. Longitudinal dimensions (relative to the location of the fibers) almost do not change. A change in its own moisture affects the transverse dimensions - its natural decrease leads to drying out.

Therefore, when a wooden house shrinks, the height of the wall and the vertical size of the window opening decrease.

The only difference is in the order - first they mount the window sill, and then they fix the frame.

Important! When installing a window, make sure that the side fastening of the window profile to the casing is not through.

When foaming the window, the mounting seam is protected from the penetration of water vapor from the side of the opening and the room with a vapor-tight film, and from the side of the street - with a moisture-resistant vapor-permeable membrane (the so-called warm installation).

Finishing the window with platbands protects the seam from the influence of climatic factors and the destructive effect of solar ultraviolet radiation (plus a decorative function).

A house built of wood undergoes certain changes during the entire period of operation. It can dry out, sit down and return to its previous parameters. This feature does not allow tightly fixing windows and doors in the opening, as is done in concrete and brick structures. To insert frames into openings, a window frame is made in a wooden house. It is also called casing or window frame, to which a frame or door is attached.

What is wood window casing

In the modern construction market, recently there are often houses made of a log house, a shield or a bar. These are baths, and country houses, and country houses. Despite the fact that new technologies allow the creation of innovative building materials, environmentally friendly wood remains in demand. In addition, such structures have a beautiful appearance.

A feature of wooden buildings, which is called shrinkage, occurs under the influence of temperature factors. Wood is able to absorb water and dry out over time. The most vulnerable modules of the house are windows and doors, or rather, their openings. Such movements of the building can disrupt their functionality or lead to complete destruction. To avoid this, a special technology for their installation is used, in which a pigtail is inserted into the opening. It is a wooden box made in a special way.

The technology for installing windows in wooden houses provides for the installation of a box

The structure of the casing includes: a window sill, a top and two sidewalls. The boards that are used for its manufacture are about 25 cm in size. A material is chosen that has a moisture content of about 10%. You should not take drier wood, as it may have cracks invisible to the eye, as a result of which it will begin to collapse when the building shrinks.

Classification of casing types for wooden structures

Specialists classify structures into several types, taking into account different features.

The cheapest and easiest way to set up a casing is a mortgage bar

Depending on the form of the casing, they are divided into:

• Casing "mortgage bar". This is the most inexpensive type of pigtail. From an ordinary board, the thickness of which is 30-50 mm, a box is made. From the inside of the opening, a groove is cut out for the timber. This simple design is very quickly assembled, but it is worth remembering that, having chosen it, you will have to finish the slopes after installing the window.
• U-shaped, they are also called "in the deck". This classic look is made by cutting a spike at the end of the wall, on which the vertical elements of the pigtail are installed. A log house moves along them during shrinkage. This design allows you to remove the load on window and door openings and allows the frames inserted into them to function correctly. The pigtail is impregnated with an antiseptic solution and insulated between the spike and the groove. To avoid drafts, a wind lock is made under the windowsill. A soft insulation is laid over the upper part of the casing.
• T-shaped casing or, as it is also called, “into a spike”. A groove is cut in the end part of the opening, the side parts of the box are made with a T-shaped profile. On the casing risers, you need to glue the bars that provide stiffeners that hold the pigtail in a certain shape. In the manufacture of this type of box, it is necessary to strictly adhere to the technology. Do not fasten the bars with nails or self-tapping screws, this will affect the freezing of the opening. Be sure to treat the tree with an antiseptic and insulate the seams with special material.

The type of pigtail and the method of installation are selected in accordance with the features of the structure

The type of casing is chosen depending on the structure. What is better to do in a particular case, a professional will tell you.

In addition to the listed types, builders distinguish the following types of casing:

• Draft. This type is inexpensive and suitable for buildings whose openings will be finished in the future.
• Finishing. If you choose this option, then in the future you will not have to finish the slopes.
• euroobsada. This type will require additional finishing of the slopes. A special feature is the use of adhesive material from solid pine lamellas.
• Power. Experts advise using this option in an arched opening, as well as using it for panoramic windows, balcony blocks.
• Arched. This option is used to strengthen the arches. They are made from both solid wood and glued beams. The cost will depend on the type of material from which the casing is made.
• Combined. When using this type of pigtail, you need to know that the base of the box is made of coniferous wood, and the top layer is glued from oak, pine or beech slabs. This option of casing is more expensive.

Appointment of casing in the construction of wooden structures

Such an element is mandatory in the design of the whole house. Its absence leads to the fact that the window opening can completely collapse under the influence of shrinkage of the house. In addition, if the wood dries out significantly, cracks and gaps will appear between the frames and the wall of the building, which will lead to large heat loss and drafts.

It is very important to use a pigtail if there is a small distance between the windows.. A design made in accordance with all the rules will decorate your wooden house.

An okosyachka protects the window opening from destruction during shrinkage of the house

Please note that wooden window casing is not always suitable for PVC frames.. If you decide to replace the old wooden windows in a wooden house with plastic frames, you need to pay attention to the pigtail when dismantling. If it is not suitable for a new plastic window, then it must be dismantled and a new one installed, carefully observing the technology.

Properly installed frames made of PVC material will serve you for a long period of time. And if you choose the color of the film covering the plastic structure, which resembles natural wood, this will allow the products to look harmonious, combined with the entire wooden structure.

Making a pigtail with your own hands

Before creating a casing with your own hands, you need to prepare the tools for work:

• jigsaw;
• grinder;
• drill;
• chainsaw;
• screwdriver

The first and important point is the choice of window design (plastic double-glazed windows or wooden windows), the choice of casing depends on this. If plastic frames are installed, a support threshold will be required. With a wooden version of the windows, such a sill is not needed.

On the sides of the opening, you need to cut a groove for the timber, which will protect the logs from moving out. In this way, a kind of skid is obtained, along which the logs slide without pressing on the window.

The upper part of the casing is installed last.

Installation is done like this:

• the lower part is being installed;
• side elements are attached;
• Finally, the upper part is attached.

A gap is left between the upper part of the pigtail and the opening to compensate for the shrinkage of the structure. Insulating material is laid along the perimeter between the casing and the wall. Do not use mounting foam when installing pigtails.

After completing the installation of the box, proceed to the installation of the frame. If the frame is plastic, then you need to cut a wooden layer along the outer part of the opening. This will create an emphasis for the plastic window and will not allow it to deform.

The parts of the casing are interconnected in the following ways:

• wedge connection;
• self-tapping screws;
• spiked connection.

Okosyachka in a spike with a ready-made slope

If the box is connected with self-tapping screws, be careful that they do not stick into the wall logs. Having completed the installation of the box, proceed to install the window and finish the outside and inside. The slopes and the window sill are made of plastic if the frame is plastic. When installing a wooden double-glazed window, the slopes can be plastered. On the outer part of the window, a low tide and platbands are fixed.

Technological stages of casing installation

For the successful installation of a pigtail, a prerequisite will be compliance with the technology:

• an opening is sawn in the wall, which is located at a height of 80 cm from the floor;
• a groove or a ridge is cut out - it depends on the type of casing chosen;
• all wooden elements are impregnated with an antiseptic solution;
• insulate the opening around the perimeter using heat-insulating materials.

The casing box is mounted with the obligatory observance of the technology

It is necessary to take measurements for ordering the manufacture of plastic frames after preparing the opening and installing the casing. This avoids incorrect sizes.

Features of creating and installing a box for plastic frames

When installing a pigtail in a wooden structure, you need to know some of the features of its installation. The box can be about 26 cm wide. Larger widths are also used, but this sometimes causes cracks in the casing. It is recommended to make a box using materials whose moisture content is 10-12%. The drier the raw material, the more likely it is to crack..

For the installation of PVC windows, a complicated version of the casing is used.

When installing plastic frames, a complicated version of the casing is suitable. A carriage with grooves is made and a comb is sawn out.

A structure assembled from a bar with grooves for a comb is called a pigtail carriage. The size of the grooves is made so that the frame slides easily along the guides when the house shrinks.

The price for the manufacture of casing depends not only on the size of the opening, but also on the raw materials from which the house itself is built (log house, log or timber). To get a quality product, you should order it from trusted builders. To do the casing with your own hands, you need to understand all the nuances of the process and purchase the required tool for the job.

When starting to install windows from a plastic profile into wooden walls, please note that you cannot insert them without a pigtail. It will help create conditions under which the frame will serve you for a long period of time without deforming or requiring repair.

No wonder the people associate the house with the fortress. The building must have high reliability indicators in order to stand for several decades, or even more. Building a house is not particularly difficult, especially in our time, when modern technologies are at the disposal of people. But keeping it in its original form is already a more serious matter. At the same time, a significant role is played by the casing box in

Of course, building private real estate from other, much more durable materials has more advantages. However, wood has a special magic, because there are still admirers of the good old Russian construction technology.

Features of shrinkage of houses

Any wooden structure is characterized by shrinkage, which is due to the natural property of wood to dry out due to a decrease in moisture levels. In a slightly different way, this is called shrinkage. This process can be influenced by a number of factors, including the following:

• initial dimensions of building materials;
• the type of wood used;
• wood processing technology (in particular, drying);
• operating conditions of the building;
• overall dimensions of the house;
• construction season (winter or summer);
• construction technology;
• the experience of specialists, and, accordingly, the quality of the assembly of the house.

The need for a casing in the house is also due to the fact that different wood shrinks differently. That is, based on the height of the house per 1 meter, buildings undergo shrinkage:

• from logs ≈ 150 mm;
• from a bar (planed and unplaned) ≈ 60 mm;
• from profiled timber ≈ 40 mm;
• from glued laminated timber ≈ 20 mm.

More accurate data are contained in regulatory documents, but it is worth considering that theoretical information may differ from practical indicators.

What is a casing box?

Such a necessary element is otherwise called a pigtail, or, in a popular way, a casing. In fact, this is a wooden box that is placed in window or wooden openings before windows or doors are installed. The whole structure consists of several components, which include tops, risers and a window sill.

At the same time, there are some features in the manufacture of the casing box:

• The width of all elements should not exceed 260 mm. Otherwise, the entire structure will be covered with cracks.
• The moisture content of wood is also important and should be at least 7-9%. Otherwise, cracks cannot be avoided either.
• A simple casing is needed for simple wooden windows; for plastic structures, a complicated support with a gun carriage is required.

At the same time, the pit for windows and doors can be of different shapes. That is, in addition to the standard rectangle, it can be a trapezoid, a polygon, or it can be made in the form of balcony blocks.

The need for a box

Do you really need a casing box or can you do without it? Here it is important, first of all, to take into account the fact that the shrinkage of a wooden house does not occur in one day or even a month. As a rule, it takes 2.5 years. Moreover, often in the first year the building will sit down by only 20%, and the remaining 80% fall on the next one and a half.

The importance of casing boxes for wooden houses cannot be underestimated, since some undesirable processes occur due to shrinkage. In particular, the inevitable cracking of logs, the disks begin to shift. In the absence of a pigtail, the top logs will press against the window or door frames with force, which will lead to distortions. As a result, windows and doors may stop opening altogether. It also adversely affects the wall cladding, which leads to the formation of cracks.

Ultimately, this can lead not only to damage appearance. The entire building, if no action is taken, can literally completely fall apart.

That's why casing is needed, which is a good protection for windows and doors from distortions. In addition, its service life, as a rule, is not limited.

What is a pigtail?

According to the manufacturing technique, the casing box can be of several types:

• Type-setting adhesive.
• In the form of a pine tree.
• Combined option.

For typesetting and adhesive pigtails use edged material with a moisture level of 7-9%, which is still acceptable. Without fail, all existing defects are cut out, be it resin pockets, knots and other varieties. After that, the material is spliced ​​along the length and width by means of a special adhesive composition. Finally, it is machined and polished.

For pine option, first a round tree trunk is sawn, and the resulting gun carriage is dried to a moisture content of 10-12%. At the next stage, trimming into blanks of the required dimensions takes place. Finally, the finished product undergoes special processing using a machine to form the required profile.

At combined casing risers and apex can be made of solid pine. While the type-setting and glue technology is suitable for the window sill. This option for installing a casing box is only suitable when it is not planned to carry out interior window decoration in the future.

Independent production of casing

There is nothing complicated in the manufacturing technology of the pigtail, and any owner is able to cope with such work on their own. All that is required is certain knowledge regarding the products themselves. It is also simply impossible to do without a number of tools.

When preparing the necessary materials, you should also take care of personal safety - we are talking about a protective mask with a respirator. And with these assistants, the whole process will be greatly simplified and accelerated:

• drill;
• screwdriver;
• wood sanding machine;
• saw (circular or gasoline);
• jigsaw;
• drill;
• measuring tools.

For any household owner of the house, they are always at hand, as they are stored nearby.

Box for plastic window openings

Many owners of private real estate, thinking about installing casing boxes, choose mainly plastic windows. In this case, advance preparation is indispensable.

First of all, you need to understand that the dimensions of the frame should be 15 cm smaller than the window opening. You also need to make a carriage with a groove in the end part of the opening and cut out a comb, which will be the base. Due to this, during the shrinkage of the house, the wood will settle along the grooves directly in the gun carriage, which will avoid a lot of pressure on the windows.

The carriage is made of wood 100 x 150 mm, and in its center it is necessary to make a groove, inside which a comb is placed. The upper part of the pigtail is made of boards 40 x 150 mm, on both sides of which it is also necessary to make grooves for the comb.

After that, the upper part of the casing is located on the crest of the window opening. And when the side carriages are installed, the crossbar is fixed with self-tapping screws. Only here care must be taken not to allow the screw to accidentally fall on the comb. Otherwise, hard adhesion may occur and the functionality of the casing for windows in a wooden house will be impaired.

At the end of all work, it is necessary to process the gaps with tow or any other insulation. And the grooved ridges need to be caulked.

Box for wooden window openings

If wooden structures are placed in the window openings, then everything is not so difficult here. Only first on the surface of the walls that will be adjacent to you need to carve grooves. Subsequently, casing beams will be installed in them.

To begin with, the lower beam of the pigtail is placed, which will avoid displacement of the side elements. And before installing them, you need to lay an interventional sealant. For this purpose, you can use jute or linen tow.

The top element of the casing is placed last. A shrinkage gap should be made above it, which is also filled with jute or tow. Such a consistent assembly will provide windows with good protection against deformation during shrinkage of the house.

Door frame

Essentially, a door frame is almost identical to a window frame, with a few minor differences. Only here there is one important point: the installation of the door frame should be carried out only after a year, and preferably 2 years after the construction of the house. During this time, the main period of shrinkage should pass.

Everything else is done in the same way. That is, if a wooden door is placed, then grooves must be made in the side surfaces of the opening. And for plastic or metal structures, it is necessary to make a comb, on which a box with grooves is already installed. During the shrinkage of a wooden house, the comb will be inside the groove.

Additional fasteners are not required to install the door frame. Only between the opening and the box should lay the material to ensure heat and sound insulation. This can be done with both tow and jute.

Public opinion

On the Internet, you can find different reviews regarding casing. Someone asks about whether it is necessary to maintain the due date after the construction of the house (1-2 years). Some in response advise putting the pigtail right away, which is confirmed by many builders.

There is also an opinion that a window block can be installed without a casing box. However, hacks or incompetent "specialists" think so. But a pigtail is a necessary measure, and the vast majority of owners of wooden houses think so!
