Piglet in a wooden house - types, drawings, features of self-production. How to make a door frame with your own hands - basic types and drawings of door openings in a house made of timber

A wooden house is an excellent structure, which is at the same time distinguished by reliability, high quality, environmental friendliness and a long service life. The latter is only possible if the house is well looked after, and during construction, all the nuances that may affect the condition of the structure are taken into account. The specificity of wood is that over time it can change its properties; in order to avoid destruction of the house, the tree must be strengthened at the stage of its construction.

During the operation of the house, many owners noticed that the wood dried out over time, the walls and roofs put pressure on the foundation, leading to a gradual shrinkage of the house. Installing a socket prevents rapid destruction of the structure. The sapling ensures that the logs and their movement cannot disturb the stability of the house.

Installing a door frame primarily affects the protection of doors from sagging and clogging. It prevents the pressure from the walls from moving the door.

Protecting walls and doorways is a very important step; if you skip it, you can very soon feel changes in the structure of the house. The work must be carried out responsibly, since the future of the structure depends on its quality - it must be safe for those living in the house. Thanks to the socket, the connection of the logs is improved and the pressure of the materials on each other is regulated.

Functions of the pigtail:

  • Protecting the doorway from the fact that one day it may warp and jam.
  • Relieving the load of the weight of the walls on the doorway.
  • Preventing door damage. In this case, the material from which the doors are made is completely unimportant.
  • Preventing gaps and cracks between logs.

The trimming of doorways is a must. It will avoid shrinkage, provide the required technological gap, improve the connection between wooden structures, and make the installation of windows and doors easier. The edging must be completed no later than 10 years after the building was erected.

Door frame: design

You can make the pigtail yourself. But, of course, for this you need to understand all its components. Each element performs specific functions. The design will be of poor quality if any of the elements are done incorrectly or skipped altogether.

It is important to remember that wooden walls exert a certain load, so all materials for the frame must be of high quality and durable.

There are many methods for constructing a pigtail - each method has its own characteristics and characteristics. Each master can choose the method that he considers the most reliable and convenient for implementation. The technology for performing the work depends on how familiar the master is with the sequence and complexity of construction work. The choice of method also depends on the characteristics of the wooden house.

What does the pigtail consist of:

  • Sidewall. Consists of side posts that connect to the wall. It is a guide that will allow the walls to move so that the shape and structure of the opening is not damaged.
  • Vershnik. It is a strip that is connected to the sidewalls. This is a horizontal spacer that affects the retention of the contours of the opening and the formation of a shrinkage gap with the seal.
  • Threshold. Represented by the lower part of the opening. He takes on the main load.

To install the embedded beam, the side parts are processed and recesses are cut into them. The recess is filled with a bar of the appropriate size. If the monolith tenon method is used, then the embedded beam and part of the box are formed together, so that the part is cut out and driven into a pre-made groove.

Types of casing of doorways in a wooden house

The window frame allows you to strengthen the walls in the openings and prevent their curvature. If the distortions have already occurred, then the pigtail can correct the situation by fastening them and aligning them. It also protects the house from the penetration of cold air and moisture. At the same time, warm air remains in the room - the window acts as a sealant.

The pigtail allows you to prevent shrinkage of the house, stop the processes of its destruction and deformation.

The pigtail not only protects the house from destruction, but also has a beautiful appearance. The sapling may differ by type. They differ in manufacturing and installation methods and in price.

Types of casing:

  • Chernovaya. High-quality casing at low cost.
  • Finishing. This option does not require cleaning the slopes.
  • Eurocasing. There is also no need to clean the slopes.
  • Power. It is usually installed in arched openings, large windows and large doorways.
  • Combined. It is inexpensive and stylish in appearance.
  • Arched. Consists of solid pine.

The production time for different sieges depends on the size and quality of them. It is important to choose high-quality materials, as well as calculate the dimensions of the casing in advance. Today, manufacturers offer a wide range of inexpensive, but quite practical and durable casings.

Tips for installing a frame under a metal door

An independent joint should be performed only when the master is confident in his professionalism. If a beginner gets down to business, he must first familiarize himself with the recommendations of professionals, otherwise all construction work may be ruined. In order to make a joint, you need to take care of a set of professional tools.

To carry out construction work, you should definitely prepare a chainsaw, circular saw, jigsaw, drill, screwdriver, and grinder.

Inexperienced builders can neglect very important points, which can negatively affect the repair and provoke unpleasant consequences. When making the design of the pigtail, it is important to remember that the safety of being in the house largely depends on its quality. Advice from professionals will help you do everything right.

Tips from the professionals:

  • Polyurethane foam must be of high quality. To seal voids, you do not need to use a sealant, which is often used when installing windows and doors. It is too hard, which ruins the whole idea of ​​the joint.
  • It is important to ensure that the self-tapping screw used to secure the door frame does not get into the block. Shrinkage should occur naturally, and rigidity interferes with this.

When installing the frame on metal doors, you must first install a frame with grooves on the ridge. The ridge itself should be placed inside the groove. Doing renovations for the first time. It is important to pay attention to the fact that construction work is difficult to carry out and even the simplest installation methods require professional knowledge and skills.

Door frame in a wooden house (video)

Installing a frame is an important step in building a house. It does not have to be done right away, but it is important to do it within the first ten years, otherwise it will be impossible to save the structure of the house. The window frame allows you to strengthen the house and create support so that the wooden boards do not shrink. This is the primary task of the pigtail. It should be noted that doing it yourself is extremely difficult. Especially if the master is dealing with her for the first time.

Over time, wooden houses experience significant shrinkage due to the fact that the wood dries out.

Wood twists and bends, which can cause warping and damage to windows and doors. To prevent shrinkage of the house from leading to deformation of window structures and doors, you need to make a frame or casing.

The cap protects the openings from pressure from above and creates the gap necessary for shrinkage. The side parts of the pigtail have poses that create vertical sliding. Most often, the pigtail is made from coniferous wood. It consists of a top, sides and a window sill (threshold).

Important! The casing must be installed before caulking works.

U-shaped pigtail (in a deck)

Classic pigtail. To perform this, a tenon is cut out at the end of the wall, a vertical part of the casing with a groove is installed on it, along which the frame moves vertically due to shrinkage.

Thanks to this, no pressure is placed on the door and window structure, which guarantees their correct functioning and durability. The casing is treated with an antiseptic, and soft insulation is placed between the tenon and groove.

A wind lock provides protection against blowing under the window sill. The gaps above the top of the pigtail are closed with soft insulating material.

T-shaped socket (in a spike)

The T-shaped frame is made as follows: a groove is cut at the end of the opening, and the side parts of the casing have T-shaped profiles. Bars are glued into the grooves on the risers of the frame, which act as stiffeners; they guarantee the stability of the shape of the casing and uniform shrinkage of the walls.

When installing a T-type pigtail, strict adherence to technology is required. For example, if you secure a block with nails or self-tapping screws, there is a possibility of freezing or blowing through the window and door opening. An important role in casing is played by antiseptic treatment and insulation of seams with compressible material.

A U- or T-shaped pigtail is selected depending on the house. When visiting the site, the surveyor will tell you the most suitable type of casing. Our craftsmen professionally perform the full range of work on the manufacture and installation of casing in wooden houses.

Stages of installing a casing (casing)

1. The opening cut is made at a distance of 80-90 cm from the floor; when determining this distance, the person’s height is taken into account. Between the opening and the window or door structure, you need to make a shrinkage gap of 35-60 mm.

2. Preparing the opening. Using a chainsaw, depending on the type of socket, a groove or ridge is cut in the opening.

3. Treatment and insulation. After installing the frame, its surfaces are treated with an antiseptic, and insulation is placed in the gaps. When installing the frame, you cannot use foam, since the window structure must move freely vertically.

4. Installation of wooden elements. At the end, the installation of wooden elements is carried out, namely the window sill, sidewalls and top.

What affects the price of casing?

1. Wall thickness: wooden houses are built from logs and timber, so the wall thickness can be from 140 to 300 mm. The dimensions of the parts of the frame correspond in width to the walls of the house, or slightly exceed it. You also need to consider the width of the window sill.

2. Size of the opening: the larger the opening, the more material will be required to make the frame and the time to work. The shape of the opening also affects the price of the casing: a standard rectangular design or a complex polygonal one.

3. Quality of a wooden house: if the walls are assembled without connecting elements, the curvature of the walls occurs in the cut out openings. Then you have to additionally straighten the walls, which leads to additional costs.

Houses made of timber are assembled using nails that meet at 300 mm. Because of this, additional money and time are required to sharpen chainsaw chains or purchase new ones.

DIY pigtail in a wooden house

Modern life, with its busy pace of life, pushes people to look for an alternative place of residence or recreation. In this regard, a wooden house is a suitable option for a city dweller.

A wooden house provides the opportunity to enjoy the naturalness and naturalness of an ecological structure.

Wooden houses, due to their natural characteristics, are environmentally friendly and energy efficient, which is why today the number of adherents of building houses made of wood is growing all over the world.

When building a wooden house, special attention must be paid to the installation of windows and doors, due to their tendency to shrink, which is a characteristic seasonal phenomenon. This phenomenon is due to the fact that wood has such characteristics as drying out and shrinkage.

In this regard, when installing window and door openings, it is important to remember that shrinkage of the building can last up to five years from the date of construction, and, consequently, the openings of windows and doors change.

To prevent this deformation, window and door openings are installed in a special flashing, which is otherwise called a casing. A frame in a wooden house allows the natural shrinkage of the house to avoid damaging windows and doors and ensure safe living.

The casing in a wooden house contains 3 components:

  • Sidewall;
  • Vershnik,
  • Window sill board (threshold).

The technology for making a pigtail depends on its type; in order to install a pigeon yourself, you need to carefully study the manufacturing technologies of each type and choose the most suitable one for yourself.

A special wooden box, popularly and by experts called a “jamb” and “casing”, consists of sides, a top, a window sill board or a threshold. Their installation is carried out in a wooden house in the 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 the hallmarks of architecture, during which the structure is protected from the risk of shifting logs. You should not refuse to frame the openings, as this can lead to disruptions in the optimal functioning of windows and doors.

Casing in a wooden house: features

The width of each component element of the pigtail should not exceed 26 cm. Of course, it can be greater than this figure, but then cracks will begin to appear throughout the structure. Frames for windows and doors are made of wood with a moisture content of at least 10%. If it is less, internal cracks may appear. Care must be taken when making the pigtail.

Installation of casing in a wooden house occurs without the use of nails and other elements. For maximum comfortable sealing, it is necessary to lay thermal insulation 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 using solid wood processing, while maintaining the wood texture. In the photo you can see what this option looks like;
  2. Glue. Each element is made from a type-setting glue board. A microspike is attached to each of the four sides. All knots are completely cut out;
  3. Combined. This option is the most common. Solid pine is used to produce the top and posts. The window sill is made of glued boards. After installation, such a pigtail will need to be coated with a protective varnish.

The casing is manufactured 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 undergo interior finishing;
  2. Without selection under the window. This solution will be used when planning both interior and exterior decoration. If you look at the photo, you can see that the pigtail looks better without the selection under the window.

Do-it-yourself window trim - tools

Over time, the construction of a house made of timber shrinks greatly, as the wood dries out. It twists and begins to bend, which can cause damage to doors and windows. To avoid this you need to do a pigtail. The casing in a wooden house is the secret of its durability. In addition, along with it, the building has an attractive appearance.

The production and installation of the pigtail is carried out 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.

A window frame for a regular window

A simple do-it-yourself frame included in the construction of a house made of profiled timber or any other type includes the following steps:

  • Make grooves in the logs adjacent to the opening. A pre-prepared block will be inserted into them;
  • The block is one of the sides of the casing. The bottom beam is placed first, the purpose of which is to prevent the sidewalls from moving;
  • An inter-crown sealant, for example linen fabric, must be laid under it in advance. In the photo you can see what it looks like;
  • Next comes the installation of vertical bars. They also require a sealant to be placed in the grooves;
  • The very last thing to install is the top beam of the casing;
  • A shrinkage gap must be made above the socket. You also need to place an interventional seal in it.

Some use polyurethane foam as a sealing material. This is undesirable, since it holds the logs together and prevents them from shrinking naturally. Using polyurethane foam in making a pigtail with your own hands makes the whole process useless.

Plug for a plastic window

A slightly different method is used to make do-it-yourself casing for plastic windows.

  1. You need 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 size of the seams and the percentage of possible shrinkage;
  3. The next step is cutting out the ridge in the finished window opening. The comb is needed as a base for the carriage. In the inner part of the carriage there is a groove along which the logs will shrink;
  4. To make a carriage, you need to prepare a beam with a cross-section of 100x150 and make a groove in the middle. Place a comb on this groove. The size of the carriage should be 5 cm larger than the window. Also, the width and depth of the carriage should be equal to 5 cm. Its production is carried out in this way: all parameters are clearly marked, then the element is cut out with a chainsaw;
  5. The upper side of the casing must be made of boards with a section of 40x150 mm. It is necessary to cut grooves for the ridge on the sides of this board. After this, the top crossbar is placed on the ridge;
  6. After installing the sides, the crossbar must be secured with self-tapping screws. We must not forget that the screws should not hit the ridge. Otherwise, the structure will become rigidly coupled and 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 linen fiber. The ridges and grooves need to be caulked.

To better understand the manufactured window frames, you can watch videos from professionals.

Doorway frame

Making door frames with your own hands is more difficult than window frames. This is due to the large size of the work and the change in the entire installation technology; the process drawings also change. One of the door frame installation options:

  1. Using a plumb line and level, you need to take measurements and mark the location of the opening;
  2. Using a saw, cut out the opening according to the specified parameters. When choosing the size of the doorway, it is worth considering that the door frame also takes up a lot of space;
  3. On each of the sides, using a chainsaw, you need to cut out grooves so that a symmetrical tenon is formed. It will be necessary to connect the opening and casing;
  4. In the jambs you need to create tenons corresponding to the grooves. You can see how this is done in photos and videos;
  5. The jambs are wound in with their spikes along with the grooves, after which they are pushed apart by crossbars from the bottom side, and then from the top side of the opening. There should be a gap of up to 10 cm above the top of the pigtail;
  6. Rigid fastening of the casing to the walls is excluded. It is necessary to install the frame 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 flax fiber. We must not forget about the upper gap, the seal of which should compress without problems;
  8. After this, you need to use platbands to close all the cracks and voids. Then the pigtail will look like in the photo;
  9. And the very last, but important step is treating the entire surface with an antiseptic.

This instruction can be supplemented with a professional video. After reading and watching it, you will be able to start making your own casing for doors and windows.

It'll never be too late

Even if the frame has stood for more than two years without a frame 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 external decoration. Building a house from laminated veneer lumber involves the use of laminated veneer material.

Today, a whole industry is engaged in the manufacture of casings, so choosing the casing that suits your interior and window shape is not difficult at all. The manufacture of casing can take place for any opening parameters, but it is worth considering that unusual casings carry some disadvantages that can be dealt with.

Okosyachka: cost and pricing

Manufacturing costs can vary greatly, since the cost of a joint depends on a large number of factors. This is influenced by the quality of the wood, types of casing, its shape, the presence of decorative details, opening parameters, 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. All types differ from each other in technical features:

  • “In a embedded block” is considered the most economical option. Made from edged boards. A groove is cut out on the inner wall into which a block with a square cross-section is placed. Due to quick assembly and attractive cost, this option is popular;
  • “Spike” is a more expensive option, but differs from the previous variety in higher quality. This timber is produced with a cross-section shaped like the letter “T”;
  • “Into the deck” - has almost the same cost as the previous option. To do this, a tenon is cut into the sides of the opening, onto which a deck shaped like the letter “P” is placed.

Prices for trimming by different companies:

Company Installation according to technology Unit from. Cost with material (rub.) Cost including customer's materials (RUB)
"Department" In the embedded block m.p. 1560 1100
To the deck m.p. 2650 1200

To make a pigtail with your own hands, in addition to applying physical effort, you need to have certain skills. Installation done professionally will help avoid deformation during shrinkage. This is a kind of guarantee of a safe home.

This type of work, such as framing door and window openings in a wooden house, is a prerequisite for newly constructed buildings. Without additional strengthening, over time the house may become unsafe, so in this case a lot depends on the quality of the work.

Framing of openings is a necessary measure in wooden houses

Why do you need a pigtail?

What is a door frame? At its core, this is the construction of additional supports that will prevent the walls from moving during gradual shrinkage throughout the entire life of the building. For wooden houses, this operation is of particular importance, since the specificity of the material increases the risk of distortion of the planes. Over the years, even the highest quality wood begins to dry out, and the pressure on the foundation of the house leads to the fact that its walls and floors can change their original position.

What functions does this design perform:

  • protects the building from the effects of shrinkage;
  • ensures the presence of a special technological gap at the top of the opening;
  • improves the connection of logs;
  • necessary for installing doors and windows.

The edging must be done within the first ten years after the construction of the building, otherwise the feasibility of the operation will be lost. It is advisable to do this during the construction stage.

The door frame will protect the home from the consequences during shrinkage

Components

In order to perform high-quality edging in a wooden house, it is necessary to understand the main components of the structure. First of all, you need to highlight the following details:

  • Sidewall. These are side posts connected to the wall of the house; they act as guides along which the walls will move. At the same time, the shape and strength of the opening will remain unchanged.
  • Vershnik. This is the upper transverse strip, it connects to the sidewalls and serves as a horizontal spacer, at the same time it holds the contours of the opening and forms a shrinkage gap with the seal.
  • Threshold. This is the lower part of the doorway; in window structures, its role is played by the window sill. It bears the main load.

In order for the frame of the opening to withstand the load that the walls of a wooden house will put on it, it is best to use laminated veneer lumber. For a tenon connection, a strip with a cross section of 50x50 mm is used. To finish the slopes, an additional straight board is taken.

Components of the design of a frame for a wooden house

Basic methods

Framing door and window openings in a wooden house can be done in one of the following ways:

  • Embedding block. A recess is cut into the side parts of the opening, into which a plank of the same size is driven tightly, then a rough box is filled on top of it, and the top is fixed separately.
  • Thorn monolith. In this case, the embedding block and part of the box are a single piece; it is cut out of the block and driven into a prepared groove in the wall; a transverse strip is applied on top.
  • To the deck. The piping of doorways is carried out using the opposite principle; now the tenon is created on the side of the wall, and a box consisting of slats with a recess and a straight top is put on it.
  • Into a tenon with a finished slope. The principle of creating a frame for a wooden house is the same as in the case of the “tenon monolith” method, the only difference is that in this case a ready-made box is installed. The parts have additional protrusions that tightly fit around the opening.

The most common ways to frame openings

Today, a very popular method is the use of an embedded block; as a modification of it, the “tenon monolith” technique is also used. The technology must be selected depending on the characteristics of the building and the skills of the builders.

Sequence of work

Since it is best to make a doorway frame in a wooden house at the very beginning of construction, all operations can be divided into several stages:

  1. Formation of the opening. First you need to determine the location of the doorway. This is best done at the building design stage, since it is necessary to take into account the basic principles of architecture and distribute the load on the walls. In a wooden house, the exact dimensions can be adjusted after laying the logs; for this purpose, markings are made, and then a rectangle of the required dimensions is cut out using a chainsaw.
  2. Cutting fasteners. Next you need to prepare the mounting points. This stage directly depends on the technology used. If you plan to drive the pigtail into the prepared groove, you need to cut recesses 50 mm deep and 50 mm wide in the side sections. If, on the contrary, the strips will be put on the protrusion, you need to cut out the corresponding element.
  3. Sidewall installation. A 50x50 mm strip is driven into the cut-out recess. It should be somewhat shorter at the top so that the walls have room for movement, the joints are sealed and a rough core is nailed to the opening. Make sure that nails and screws do not interfere with the plank.
  4. Installation of the top. The upper transverse strip is placed on the prepared protrusions. Insulation, for example, mineral wool, is laid between the wall and the frame. Foam cannot be used. Additionally, the frame is fastened to the walls with anchor bolts cut at an angle. The top and sides are connected in the same way.

Next, you can install the door itself directly. Before installing the frame, be sure to remove sawdust and treat all wood with an antiseptic. If you do everything right, your home will be completely safe to live in even after several decades.

In recent years, more and more adherents of houses made from natural materials have appeared in the world. Wood is not the cheapest of them, but it is also the most popular. After all, wood is an environmentally friendly, heat-saving and durable material (with high-quality processing and skillful use). But wooden structures have a specific property - they dry out and sag. Therefore, during construction work in a wooden house, special attention should be paid to windows and doorways. The casing (casing) is a mandatory work during the construction of a wooden house. It allows you to reliably strengthen all openings in the house and prevent distortions of the logs. We offer below detailed instructions for making a pigtail with your own hands, including videos from professionals.

A frame or casing is a wooden structure (box) installed in window and door openings before installing windows and doors. Consists of a top, sides and window sill board/threshold. It protects windows and doors from deformation that may occur during shrinkage of structures.

When making casing, you should remember certain nuances:

  • elements for the pigtail must have a width not exceeding 26 cm, otherwise there is a high probability of cracks appearing in the structure;
  • the wood used to make the box must have a moisture content of at least 10%. If the material has less moisture, cracks may appear inside it;
  • a simple casing design is used only when attaching wooden windows. PVC structures require a more complex “support” with a carriage. But this is a separate question.
Window frame

The casing for a wooden house is laid in the openings using various technologies. Depending on this, there are several types of window frames used in a wooden house:

  1. "Embedded block." One of the most commonly used options due to its low cost and ease of assembly. The material used is board scraps. To ensure high-quality installation of this type of casing, a special groove is cut from the inside of the opening, into which a block with a square cross-section is placed. Next, the finishing board is attached.
  2. "The thorn is a monolith." A higher quality type of casing used in the construction of houses made of solid timber and other expensive materials. It is made from solid timber with a cross-section in the shape of the letter T.
  3. "Into the deck." The pigtail is represented by a monolithic beam, in which a groove is cut in the shape of the letter P. For the top, an edged board 5 cm thick is used.

Do-it-yourself pigtail making technology

Casing openings in a wooden house is a fairly simple process and it is quite possible to carry it out on your own. To do this, you only need knowledge of manufacturing technology and a certain set of tools.

Preparation of materials and tools

So, we prepare the necessary materials (edged boards, beams), do not forget about a protective mask with a respirator, as well as a certain set of tools that will speed up and simplify the work process:


The window opening cannot be sealed with polyurethane foam.
  • drill;
  • screwdriver;
  • wood sanding machine;
  • saw (circular or gasoline);
  • jigsaw;
  • drill;
  • measuring instruments.

Advice. The selection of materials necessary for the pigtail should be approached with special care: the beams and boards must be of high quality and thoroughly dried. It’s not scary if the wood has defects (meaning knots).

Making frames for window openings

Let's use a simple method of creating a casing. We make grooves in the logs adjacent to the opening. The first thing we drive into the groove is the timber for the bottom side of the frame (the surface must be completely cleaned and absolutely flat). It will provide stability to the sides. First, place a layer of jute or flax fiber under it (they will serve as a kind of sealant).

Scheme of a window frame

Then we proceed to the vertical beams, under which we also lay a sealing layer in advance. The last one in line is the top beam. The groove for it should be slightly deeper than the others, so that there is a small gap left after installing the beam. It will act as a compensation space if the walls of the house become deformed over time. We also fill it with sealant. At this point the installation process can be considered complete.

Advice. Some builders use polyurethane foam as a seal when installing a window frame. We do not recommend using it, since it will “tightly” fasten the logs together, which will make the process of natural shrinkage of the wood impossible and the casing will simply be useless.

Making frames for doorways

With doorways, the situation is somewhat more complicated than with window openings, due to the larger amount of work and the need to modify the drawings of the door structure when using casing. Offers you the following option for making casing for a doorway:

  1. Using a level and plumb line, we take accurate measurements for the location of the opening.
  2. Using a saw, we create an opening of the required size.
  3. On the sides of the opening we cut out symmetrical grooves for the bars (5x5 cm) and drive pre-prepared bars into them. They should be slightly shorter than the groove itself so that distortions do not occur during the shrinkage of the house. The block cannot be attached in this case! We leave it free.
  4. We seal the sides with a half-meter strip of jute. You should not seal the entire surface of the opening, since when tightening the screws it can wrap around them.
  5. Let's start installing the rough box. You need to work very carefully so as not to catch the bars in the grooves with the screws, otherwise they will fix the entire structure in one place, which will lead to the appearance of cracks between the logs in the future.
  6. We fill all gaps and joints with sealant. Then, using platbands, we close all the cracks and voids. The seams between the door and the casing can be sealed with foam/sealant and covered with casing. The casing is ready!

Doorway

We introduced you to the process of making your own frames for openings in a wooden house. Now you know that it is quite simple, but at the same time the reliability and durability of the wooden structure depends on it to a certain extent. We wish you a successful renovation!
