Plastic double-glazed windows have better characteristics than wooden structures. Due to their high performance, such windows are actively used in both concrete and wooden buildings.
Installation of plastic windows in a wooden house differs from installation in concrete and block buildings. The technology consists of a long preparation, the main purpose of which is to prevent the destruction of the double-glazed window from the shrinkage of the house. During work, you need to follow certain rules that will help extend the life of the structure.
Mounting
Installation of a double-glazed window, regardless of the age of the house, is almost indistinguishable. In both cases, installation begins with casing. It is this design that protects the window from destruction during shrinkage and natural expansion of wood.
The installation of plastic structures requires specific skills and knowledge from the master, without which the work cannot be carried out. If there is no experience in carpentry, it is better to turn to professionals. The main difficulty in assembling the casing for the window is to assemble the tongue and groove lock. It is this fastening that provides reliable connection of parts and protection of the frame from deformation.
Shrinkage of an ordinary wooden house can reach 20-30 cm, which is noticeable when using metal and plastic structures, the shape of which does not change with time. The degree of shrinkage depends on the type of wood. So the average shrinkage a year after the assembly of the log house is:
- for log houses 50-60 mm;
- buildings from a bar 30-30 mm;
- buildings from glued beams 15-30 mm.
These indicators are small, but they should be taken into account. Shrinkage of a building in the first year of a log house can lead to windows being forced through by the upper rims of partitions and walls.
Shrinkage of the building lasts up to 5 years, it depends on the humidity of the air, the size of the house and the time of year. But even after 5 years, the house still "breathes", so PVC products are installed with casing in old buildings.
Preparatory stage
To figure out how to install plastic windows in a wooden house, you will need to follow certain instructions. Before assembly, the following work must be done:
- disassembly and removal of the old structure (for old houses);
- cleaning the opening from dust, chips and old paint;
- take measurements of the opening and calculate the dimensions of the future window;
- preparation of a diagram or drawing;
- alignment of the walls of the opening in case of symmetry violations;
- for leveling use a primer, sealant and putty;
- choice of the type of future window (sash format, material color and size of the entire structure);
- definition of the product company.
When all the work described above is completed, a window is ordered according to the measurements of the opening. There are several features of the installation of plastic products.
Construction installation
After delivery, the window must be kept at room temperature. For installation you will need:
- screwdriver and drill bits;
- mallet and chisel;
- anchor fasteners;
- wedges for spacers;
- mounting foam;
- key for PVC windows;
- pliers;
level and tape measure.
The installation of a plastic window in a wooden house is carried out in pairs, since it is more convenient to do its lifting and fastening together. The weight and size of the double-glazed window does not allow you to carry it alone.
Note! It is recommended to install a PVC window in calm and warm weather (above minus 10).
Functions and types of casing structures
Casing is a box of boards that is installed around the window along the perimeter of the opening. The design device allows you to mount it with your own hands so that it “floats” inside the log house and does not depend on the shrinkage of the building. To fasten the casing to the frame, grooves are used, they are placed on the sides of the window opening. The casing itself is seated at the ends on spikes.
So that the casing frame is not blown through in winter, it is fixed with tow, linen or fiber sealant.
A small gap is left in the upper part of the casing, which maintains the integrity of the structure during shrinkage. After assembling such a frame, the movements of the log house do not affect the window in any way, and most importantly, shrinkage will not be able to harm the design of the double-glazed window.
In this case, the walls will shrink, and the window will not be damaged. Casings are divided into several types, depending on the type of fastening:
- In a mortgage bar. The fastening is based on a bar placed in a groove at the ends of the opening. In addition, it passes through the casing posts.
- Into the thorn Such designs have a special spike, which is installed on the side elements of the casing. The groove is in the logs of the opening.
- Into the deck. The spike in this case is located at the ends of the logs. There is a groove in the casing posts.
The box is a floating mechanism, during installation of which the deformation of the plastic window is impossible. Do-it-yourself installation of wooden windows is carried out using a different technology.
It is necessary to perform calculations very accurately, because even with a slight error, the risk of deformation of the box will increase. In addition, the design may be leaky. Proper installation of the box is a prerequisite for the quality of window service.
Execution of a pigtail
There are simple and complex pigtails. Each of these design types has its own advantages. For example, a simple pigtail is quickly erected, and a complex one eliminates vertical deformation of the window. When creating a simple pigtail, the option already described in the article is selected - using grooves and bars.
A complex system requires cutting a comb in the opening. A gun carriage with grooves is put on it. This design option is more reliable. During shrinkage of the house, the comb is shifted in such a way that vertical deviations of the plastic structure are excluded.
The casing is made of bars. Using a chisel, it is necessary to knock out a groove in the center of the timber with dimensions of 0.5x0.5 cm. One of the important points is to mark the ridge with your own hands. How high-quality the window design will turn out will depend on the accuracy of the markup performed.
When the comb is ready, it is necessary to begin to form an opening. The bars should be installed using a level. This takes into account the gap for shrinkage. It is 0.5 cm on top and 1 cm on each side. The frame, which is made of bars, is best strengthened using dowels. The resulting cracks are sealed with tow. Then install the plastic frame.
Plastic frame installation
After preparing and installing the pigtails, the installation of the plastic structure should begin. Installing a window without casing is a mistake. Parallels should be checked first. The gaps between the frame and the PVC double-glazed window are determined. For foaming, leave 3 cm on the side and about 5 cm on top. Then you can start directly installing PVC windows in a wooden house.
The structure must be fastened to the place intended for it on special elements. They can be purchased at every hardware store. Such fasteners are metal plates with holes.
Advice! It is better to use special fasteners, because the use of self-tapping screws does not provide tightness and thermal insulation of the structure.
Installation of a plastic window is carried out with a level. If such a rule is not followed, the design may turn out to be tilted. This circumstance can significantly reduce the aesthetic appearance of the window and its performance.
Advice! Before mounting the structure, the sashes should be removed. This will lighten the window, which will favorably affect the ease of installation.
After fixing the window in the opening, the resulting gap should be foamed. For reliable fixation of the installed structure, a bar is used. This will prevent the window from moving during foaming. When the foam dries, they should be removed. When installing windows in a wooden house in the casing, care should be taken. In this case, you will have to determine the correct position for mounting the screws. The window should not be fixed in the ridge area.
This completes the window installation process. Now it remains to put on the sashes and let the foam dry. This method of installing a plastic structure in the country is correct. If there is no self-confidence, you should call professionals. However, self-installation of a plastic window is a significant cost savings. To do the job as efficiently as possible, you need to follow the instructions.
conclusions
Do-it-yourself installation of a plastic structure in a wooden house is as simple as possible. To do this, you will need to perform accurate calculations and prepare a certain set of tools. All work is carried out with the utmost care. This is necessary for the long service life of the double-glazed window.
During work, it is necessary to follow a certain sequence of actions, as well as follow some rules. In this case, it is important to take into account the features of shrinkage of wooden walls. If you follow the advice of professionals, plastic double-glazed windows will serve you well for many years.

Installing plastic windows in wooden houses increases the thermal insulation of the entire building, reduces several times the cost of heating the room. Many doubt the possibility of performing this operation and think that some auxiliary means or materials will be required to install the structure. In some houses, it is enough to remove the old one and replace it with new PVC, while other buildings require more complex steps. To understand this, it is necessary to study the issue more carefully, to learn the recommendations of experts.
Is it possible to change old window structures to plastic ones in a wooden building?
Depending on the type of wooden house, its age, the installation of plastic windows in it can be carried out according to a simplified scheme or in a more complex and time-consuming way. But the replacement of old wooden windows with similar plastic ones is available to everyone.Frame-panel type
Due to the absence of shrinkage in such structures, replacing wooden windows with plastic frames is easy. All manipulations are performed according to the same instructions as for stone or panel structures..Log cabin
Installation of metal-plastic and plastic windows is permissible in such structures not immediately after their construction. Since logs and beams must take their place in the building structure, it is necessary to wait from 2 to 3-4 years (depending on the characteristics of the materials used).Attention
Installing PVC window frames in log houses before waiting for them to shrink is dangerous due to damage to the frames and their deformation.
Installation rules:- Shrinkage time should be 2 years or more. The timing is affected by the characteristics of the wood, the level of drying, the method of harvesting.
- During the period of shrinkage of the structure, wooden windows can be installed, which will then be replaced with plastic ones.
- It is required to organize an expansion gap of no more than 12% of the frame height, which will allow installing PVC windows immediately after the construction of the house is completed.
- Thin-section boards with tow winding on them should be used to seal the compensation gap, which will protect the frame structure from damage during the shrinkage period. As the structure subsides, such boards can be removed or left until the tow is compacted without damaging the structure.
- Installation of casing - a special box made of durable thick bars. It is used as a frame for a window opening and fixing a window on it. In the house, this element also performs a protective function, since it prevents pressure on the wall window during shrinkage.
Features of work performance
When replacing old windows with new ones made of plastic, follow the procedure:- When replacing a window with casing, measurements must be performed after removing the latter from the window opening, otherwise the measurements taken will give significant deviations.
- If the window is replaced in place of the old one while maintaining its frame, then it is necessary to take dimensions from this element after removing the window frame.
- The replacement of the pigtail (casing) is carried out first, and it is better to enlist the help of the masters, since this element sets the operating conditions for PVC windows in the future.
- When installing new windows, it is required to leave 1–2 cm for the installation gap on all sides of the opening. It is then sealed with mounting foam, but without it, installing the window correctly and without effort will not work.
- When installing new double-glazed windows, all operations are performed in the same way as for panel or stone buildings - double-glazed windows are removed from the frames, the frame structure is fixed on the box with anchors with appropriate plates, which are attached to the frame and wall with two self-tapping screws.
- Sealing tape is used to isolate the mounting joints between the frame and the walls.
- At the last step, double-glazed windows are inserted into fixed PVC frames. It is necessary to hammer them around the perimeter with plastic glazing beads with rubber insulation. This will increase the energy efficiency of the structures.
- The adjustment is carried out after the installation of the sashes and all double-glazed windows, when the load on the structure is set to what it should be during continuous operation.
When replacing a window frame, it will be necessary to use boards or bars with a thickness of 5 cm or more, and the organization of a sealing insulating layer. Therefore, measurements must be performed accurately, with the necessary allowances for the layers of auxiliary materials.
Installation options
Replacing old windows with new PVC structures in wooden buildings is done in several ways.:
- installation of a new casing when installing a plastic bag;
- installation on an existing pigtail;
- replacement with preservation of window parameters;
- expansion of the opening, installation of the appropriate filling in it.
With original hole size
In the case of such a replacement method, several operations must be performed:- Dismantling of the wooden structure.
- Check for the integrity, strength of the casing, the presence of additional fasteners on it that need to be removed.
- If the pigtail has chips, damage, signs of decay development and other significant defects, it must be removed and replaced with a new design.
- Measures are taken for the casing (in case of its replacement) and / or a plastic bag.
- Glass preparation. Installing a pigtail or cleaning an old one, installing a window frame.
- Fixing the window frame in the casing, then installing the sash on it.
- Placement in the frame of double-glazed windows, fixing all additional elements.
- Adjustment, customization of the structure.
The necessary waterproofing in the pigtail with the selected quarter is impossible, and for the installation of plastic double-glazed windows this is a prerequisite.
With a change in the size of the opening
In log houses, window openings were always made small. The owners of such buildings are always trying to make the rooms more sunny, more comfortable for living. To do this, they change windows, expand the window opening. Replacement work is carried out in the following order:
- The old design with a pigtail is removed.
- A preliminary markup is made with a building level.
- With a chainsaw or ordinary carpentry tool, a wider and / or higher opening is cut.
- The size of the new casing is calculated.
- A pigtail is being constructed, placed in the opening.
- The size of the new window is calculated, and then the settings are the same as in the case of saving the size of the window opening.
- thickness of boards, type of casing;
- the presence of a gap for the seal;
- 1-2 cm for organizing a technical opening;
- thickness of the installed window sill;
- dimensions for the expansion gap.
Attention
The marking should be carried out so that the edges of the opening intersect the logs along their central part. This requirement applies to log and log houses.
Installation subtleties
All operations for replacing old windows in a house made of logs, log houses or frame structures must be carried out according to the instructions above. Each stage from dismantling and / or changing the size of the opening to the final decorative finish of slopes, drainage, window sills and the facade should have a clear sequence. If you make any inaccuracies or deviate from the recommended sequence, then various difficulties and defects may arise, which are more difficult to eliminate than to prevent.Necessary tools and materials
When replacing old windows, you will need such a tool:
- protective equipment: gloves, plastic glasses or with rubber seals;
- impact drill, screwdriver or screwdriver with an appropriate nozzle;
- mounting foam, insulating materials, including sealing tape;
- hexagon or bolts with self-tapping screws for installing the support mechanism;
- wooden spacer wedges under the window frame;
- light mallet or rubber mallet;
- plastic chisel;
- construction level;
- roulette.
Even with the entire set of tools, third-party help will be required, since window frames, like double-glazed windows, have significant weight.
Difficulties during installation
The main difficulty associated with the installation of plastic double-glazed windows in wooden houses is the presence of shrinkage. Because of it, the frames can be deformed if the window boxes are not properly organized. This situation cannot be corrected because damaged structures will not allow the window fittings to fully function. The casing can have this type of construction: the bars are mounted in a groove made for them in the window opening. The use of a groove and a ridge carriage ensures the sliding of the groove-ridge structure during shrinkage. This will protect the window frame from damage and stress. The method of creating a wooden block in grooves without a gun carriage is only suitable for PVC bags. In wooden buildings, the installation of plastic double-glazed windows is simple. It is enough to stock up on the right tools and patience. Fulfillment without deviations and initiative of all the recommendations of specialists will allow you to easily, quickly, and efficiently replace old windows. This will significantly increase the house's ability to retain heat and reduce heating costs. If you decide to insulate your house, but at the same time you do not have the opportunity to put a new plastic window, then we suggest reading about that, for the winter and about effective ones.Useful video

Due to their performance characteristics, double-glazed windows made of PVC material have gained particular popularity among the population. They are mounted in buildings and structures built of concrete, brick, wood. It is necessary to insert plastic windows in a wooden house by following certain rules.
Important installation details
Starting the installation, you need to prepare the equipment that will be required: a building level and a plumb line, and also know how to insert a plastic window. It is necessary to install a PVC window, strictly observing the placement in the plane according to the level. This will ensure the correct operation of all elements, the sashes will not spontaneously close and open.
PVC window installation technology involves its correct placement in the plane according to the level
When purchasing plastic structures, you need to buy additional special fasteners for installation. The frame is fixed in the pigtail of a wooden structure using self-tapping screws and special fasteners.. By following the technological process and correctly installing plastic windows in a wooden house, you are guaranteed to receive window blocks that will last for a long time.
The window frame is fixed with anchor plates.
If the sashes are dismantled, the structure will become much lighter and it will be easier to move it, however, mounting metal-plastic windows in a wooden house alone is still not recommended. 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 carried out in stages:
- preparatory activities before installation;
- installation of PVC windows;
- control-checking the location in space;
- blowing 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.
Performing preparatory work
First of all, you need to take the exact dimensions by measuring the opening, and order a 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 determine the color of the structure and the completeness of the fittings necessary for the functioning of the window.
When the manufacturer delivers the products to the site, the following steps must be taken:
- 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.
Having finished the preparation, they insert a plastic window into a wooden house with their own hands.
Fastening the window structure in the prepared opening
We install the window sill first, it will be the basis for the double-glazed window, so you need to put it strictly in level (horizontally). For fastening strength, cuts are made on the sides of the box about 8 mm deep. Adjustment is carried out using plastic plates or planks. Fastening takes place with self-tapping screws to the bottom of the box. When screwing in, it is worth putting washers under the head of the self-tapping screw, this will prevent damage to the surface.
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 windows are being installed. When attaching, the handle must be placed horizontally. When all the fittings have been assembled, the installation of metal-plastic windows begins.
First you need to set the PVC frame in level. A frame is placed on two-centimeter bars and leveled horizontally using a water level. After that, go to the vertical alignment.
Having obtained the ideal parameters at the water level, they fix the frame with self-tapping screws to the pigtail, using mounting fasteners that were specially bought in the store. It is important not to get a self-tapping screw into the crest of the log where the pigtail is installed.
Fix the frame with self-tapping screws
After fixing the window element, we get 2-centimeter gaps around it for mounting foam.
Before applying the mounting 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 applied 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 set correctly and the alignment is correct. Having closed the sash, foaming is performed with foam for installation and left for complete fixation for a day.
Why is casing made for plastic windows in a log house?
To get high-quality PVC windows in a wooden house, you must strictly observe the installation features, that is, install them on a special frame (base). The need for such a design is due to the peculiarities of buildings made of wood. Unlike a building made of stone (concrete or brick), a wooden panel house is unstable over a long period.
Casing prevents deformation of the frame during shrinkage of the house
The building will sit in the first five years after its erection. 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 in a wooden house, it is necessary to create a structure for the opening, which has the name casing, they also say - a pigtail. Its direct purpose is to prevent wall shrinkage from affecting the frame, so the pigtail:
- strengthens the opening;
- bears the burden;
- prevents shrinkage.
An okosyachka looks like a box made of thick boards. The structure is fastened in the side rack to the groove, while fasteners are not used. Above the pigtail there is a shrinkage compensation gap for a wooden house. There are several options for installing it:
- a groove is cut in the log where the bar is placed. Self-tapping screws are screwed into the last element of the embedded beam;
- a groove is cut in the racks on the sides of the structure, a spike is cut 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 posts of the box.
Casing device options
To get a high-quality design, you need to follow the technology for installing plastic windows in a wooden house. To begin with, they cover the ridges 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 crossbar of the casing is mounted, and carriages (side racks of pigtails) are stuffed onto the ridges, the upper jumper is laid in the upper groove of the racks. After collecting the box, carefully connect it with self-tapping screws, it is important that they do not fall into the logs.
The cracks that are visible in the opening after the installation of 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.
Cracks are sealed with insulation or tow
The compensation gap is filled with flat planks pre-wrapped with tow. When shrinking, the walls are gradually knocked out. To do this, remove the upper casing and, having knocked 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 wooden trim. When ordering PVC windows in a wooden structure, you should look at the option for the wood texture, this will allow them to look harmoniously against the background of a logged 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 bit more, but are a better option for a natural-material home.
When ordering, it is important to correctly measure the opening and not make a mistake in the width of the window sill. Self-installation of a PVC window in a wooden house, knowing all the nuances, is not such a complicated process. You can do it yourself, without resorting to the help of expensive installers.
Do-it-yourself installation of plastic windows in a wooden house
I hope no one will argue that since the moment they appeared on the construction market, plastic windows have proven themselves only on the positive side, although there are a few unpleasant moments, but still. It is because of the excellent performance and ease of installation that more and more homeowners prefer them. PVC windows can be easily installed in any window opening, but when installing in a wooden house, you need to take into account a number of nuances, without which all your work will go down the drain. Further on the article we will consider what these nuances are and we will analyze all the stages of installing windows with our own hands.
Materials and tools
To accomplish this task, in addition to PVC windows, we will need the following materials:
| Characteristics | Purpose | |
| bar | 150*100 | Casing installation |
| Board | 50*100 | Casing installation |
| Lnovatin | Insulation of the sides of the casing | |
| Quality insulation | Insulation of the thermal gap on top of the casing | |
| Thermal waterproofing tape | Thermal gap waterproofing | |
| Galvanized self-tapping screws | Casing fastening | |
| Screws for concrete | Nagel MRS | Fixing PVC - windows |
| Linings | Plastic | Window installation |
| sealant | Seam sealing | |
| Mounting foam | Closing the gap between frame and casing |
From the tools we will prepare this:
- Perforator, drill, screwdriver;
- Chain saw, ordinary saw, grinder;
- Hammer and rubber mallet;
- Paint knife, ordinary knife, pliers, furniture stapler, screwdriver;
- Building level, tape measure;
- Foam gun.
Preparatory work
1. We dismantle old windows (if any), check whether there is a pigtail or how it is also called casing and what condition it is in (casing is the most important element of a window opening in a wooden house and therefore this stage is very, very important). If there is a pigtail and it is in good condition - you are lucky, you got rid of a lot of work, if it is not there or it is in a deplorable state, then read below how to install it.
2. We check the opening for defects, such as rot, chips and eliminate them.
3. We process the opening with a special composition intended for wood, of which there are a lot in hardware stores and proceed to the main work.
Instructions for installing PVC windows
Step 1: As I wrote above, the pigtail plays, perhaps, a key role in our task of installing plastic windows. But first things first, the casing is such a structural element that prevents the windows from deforming during the shrinkage of a wooden house and therefore its installation is mandatory.
There are several modifications of this design, namely:
1. Casing in a “mortgage block”;
2. Casing in the "deck";
3. Casing in the "thorn monolith";
4. "Fine" casing box.
Most often, the last two options are used, we will also not reinvent the wheel and will make a “monolith spike” casing.
First: Knowing the dimensions of the future window, we mark and cut out the corresponding opening.
Advice: From above, we cut the window opening 5 - 10 cm higher than the pigtail will be installed. This is done in order to provide a thermal gap.
Second: We mark the future groove, usually it is made five centimeters in size. After marking, select the groove with a chain saw.
Third: We process the side bars. At the first stage, we should get a t - shaped bar “monolith spike”. After sawing out this figure, we just have to make a bed for the top, that is, the upper jumper, it all looks like this.
Advice: If it is planned to finish the house from the outside, then we buy rough material, but if the house is not additionally finished outside, then we use finishing material based on glued laminated timber.
Fourth: We process the window opening and all the elements of the pigtail with a special tool that protects the tree from decay and other troubles. At the same stage, it is necessary to make thermal insulation between the wall of the house and the pigtail; for this purpose, it is best to use lnovatin.
Fifth: We install the side elements of the casing, then we measure and cut the board for the top bar (top). The top bar needs to be cut out so that it fits into the groove of the side bars with little effort. After installing all the elements, we fix them to the walls of the house with the help of self-tapping screws.

Sixth: We insulate the thermal gap left on top of the casing, this is best done using high-quality insulation installed both on the outside of the window and on the inside. Then, the insulation is necessarily hydro- and vapor-insulated with a tape specially designed for such purposes, such a tape has a self-adhesive strip, but for a more reliable fastening it is better to walk on it with a furniture stapler.
From all that I described above, the following should turn out:
Important: Never use mounting foam to isolate the thermal gap, because after hardening it will turn into a very hard substance that will transfer all the loads associated with shrinkage of the house, windows and the pigtail will cease to perform its functions.
Step 2: We proceed directly to the installation of a plastic window in a wooden house, this step, like the previous ones, will be divided into several stages.
1. We take out a double-glazed window from a window frame. We start with the opening sash, insert the handle into the groove and move it to the open position, the sash does not need to be opened. We remove the rod of the upper hinge, open the sash and remove it from the lower hinge.
2. We remove the side glazing beads from the “blind” sash, for this, with a thin object, for example, with a knife, we bend the glazing beads towards the double-glazed window and back, they should click and remove them. After all the glazing beads are removed, we put on gloves, since the edges of the double-glazed window are very sharp and carefully remove the double-glazed window.
Advice: To avoid falling out of the double-glazed window, first remove the side glazing beads and only then the lower and upper ones.
3. We drill holes in the frame for fasteners. For this purpose, we use a drill 6 * 70 or longer. We drill holes for fasteners at a distance of 15 cm from the corners and imposts of the frame and no more than 70 cm from each other.
4. We try on the prepared window frame, having previously placed plastic linings under the corners and impost. Then we align the window frame using the same linings and the building level, applying it to the attachment points of the glazing beads and installing linings where necessary. Make sure that the upper part of the frame does not rest against the casing. The gap at the top must be at least 1 cm.
5. After the frame is leveled and the necessary wedges are placed, we proceed to drilling the walls. You cannot cope with such a task alone, because one person will have to drill, and the other will have to hold the window box and look at the level so that the verticality of the window does not go astray. To begin with, we drill two holes at the top and bottom of the box, insert screws into them, for fastening we will use concrete screws (MRS dowel), we twist them, but not completely, as it may be necessary to adjust the lateral deflection of the window box. After leveling the window, tighten all the screws.
Advice: It is not necessary to tighten the screws too much, as you can knock down the verticality of the window. It will be enough to slightly drown the head of the screw into the plastic.
6. We foam the gaps between the window frame and the casing. Fifteen minutes later, as soon as the foam hardens, you can insert double-glazed windows and finish the window opening. We will not touch on fine finishing in the framework of this article, since this topic is very extensive.

Do-it-yourself installation of plastic windows in a wooden house: installation features, instructions, video
Plastic double-glazed windows have gained popularity because of their performance. But can they be used in the construction and repair of wooden buildings? Of course, you can and should.
Installing plastic windows in a wooden house has a lot of differences and features. The process includes a number of preparatory manipulations, primarily related to the fact that the structure tends to sag over time.
We install a PVC window in a private house
Features of the technology for installing PVC windows in a wooden house of a new or old building do not have a strong difference. In any case, experts recommend technology using casing - time-tested, this technology allows you to avoid deformation, regardless of the material from which it is made.
Installing a plastic window in a wooden house or cottage with your own hands will require some knowledge and skills from the performer. Of course, if there are none, then it is better to turn to specialists. The complexity of the self-assembly of PVC systems in a wooden house lies in the fact that the frame is attached using the tongue and groove mechanism. This design allows you to create such operating conditions in which the deformation and subsidence of wood does not have a direct effect on the double-glazed window.
According to statistics, a wooden house can shrink up to 30 cm. Depending on the material, due to the drying of wood for 1 year after the construction of the building, the amount of shrinkage of the structure per meter of height is:
- log: 40-60 mm;
- beam: 30-40 mm;
- beam glued 10-30 mm.
These factors should not be neglected, since the subsidence of the structure already in the first year threatens to crush the window with the crowns of the wall structure.
Shrinkage of the walls can also occur after 5 years of operation of the house under the influence of seasonal changes in the composition and humidity of the air. At the same time, the installation of windows in old houses also implies the presence of casing.
So, consider the algorithm for installing PVC systems in wooden houses.
Stage number 1. Preparatory work
Before starting direct installation, it is necessary to carry out a number of preparatory measures:
- dismantling the old window (if replacement is taking place);
- cleaning the opening from dirt and debris;
- make the necessary measurements and calculations;
- drawing up a drawing and fixing the measurement parameters of the opening;
- alignment of the contours of the sides of the window opening, if the hole has an irregular shape;
- alignment is performed using putty or sealant;
- decide on the design and functionality (number of doors, their size, which of them will open);
- determine the manufacturer and color of the product.
Only after completing all the above manipulations, we order a window from the manufacturer, taking into account individual wishes.
Stage number 2. Installation
As soon as the windows are delivered and the necessary preliminary work has been carried out, you can proceed directly to the installation. Tools:
- drill;
- construction level;
- chisel;
- screwdriver;
- roulette;
- mallet;
- pliers;
- anchor plates and bolts;
- key for adjusting windows;
- mounting foam;
- spacer wedges;
- spray bottle with water.
Casing: purpose, types and design
The casing is a box-shaped structure, which is made of three or four boards and installed around the perimeter inside the opening.
The system allows you to install a plastic window yourself, so that the window is fixed independently of the main wall structure and has a floating character. The window system is fixed with the help of grooves on the side, which are mounted on spikes protruding from the end of the logs and timber.
To fix and seal the casing, only tow, linen or fiber insulation is used. In any case, mounting foam.
Thus, the shrinkage of the walls of a wooden structure in no way affects the window and, moreover, will not damage it. Depending on the fasteners, casings can be classified into the following types:
- into a spike. Such a design is characterized by the presence of a spike, which is mounted on the side parts of the casing, and a groove, which is located in the logs of the opening;
- in a mortgage bar. The basis of the fastening is a bar, which is placed in a groove at the ends of the opening and passes through the casing posts;
- into the deck. The spike is located at the ends of the logs of the window opening, but the groove is in the casing posts.
The box is a floating mechanism that excludes deformation of the plastic window during operation, regardless of the type of casing installation.
Calculations should be made with high accuracy, since even a slight error can lead to deformation of the window frame or leakage of the structure. In addition, proper installation is a guarantee of the quality of the plastic window itself.
How to make a pigtail (casing)
The design can be of two types: complex and simple. A simple pigtail is the system described above, with bars and grooves. The complex design is performed somewhat differently: a comb is cut out in the window opening, on which a carriage with grooves is put on. This option is more reliable. When the walls shrink, the comb can slide and does not allow vertical deviations, excluding pressure on the window frame.
The casing, as a rule, is made of timber. Using a wood chisel, a 0.5 cm groove is knocked out in the center of the beam, and a spike (0.5x0.5x.25 cm) is cut out from one end. A comb with spikes 0.5x0.5 cm is cut from the end of the opening logs. To do this, you can use a saw or a chisel.
After the comb is ready, we proceed to install the risers and form the opening structure between them. The bars are set according to the level, taking into account the gaps for shrinkage of the walls (1 cm on the sides and 0.5 cm on top). The frame of the bars is strengthened with the help of grooves with the main canvas of the walls and dowels between them. The gaps left are sealed with tow or other fiber. That's all, now you can proceed with the installation of the plastic frame itself. You can see the process in more detail in this video:
Stage number 3. Installation in the prepared opening
After carrying out the necessary preparatory work and installing the pigtails, you can proceed with the installation of the window.
To begin with, we check the dimensions and location of the parallels, the gaps between the casing and the frame. The stock for foaming should be: 4-5 cm at the top, 2-3 cm in width and height, 3-4 cm in the window sill area. After making sure that the stock corresponds to these indicators, we proceed directly to the installation of a plastic frame.
The window is fastened with special fasteners, which are sold at any hardware store. They are metal plates with holes.
Installation of a plastic window should be carried out according to the level. If you neglect this factor, then you risk getting a tilted design, which significantly reduces the operational and aesthetic objectives of the window.
After the window is fixed in the opening, it is necessary to fill the gap with mounting foam. To avoid displacement of the structure during foaming, bars are placed that will maintain the position of the frame without deviations. After drying, do not forget to remove it.
Securing the window in the casing is done with care. In this case, it is necessary to choose the correct location for tightening the screws. Under no circumstances should a window be fixed in the ridge area!
That's all, we finish the process by completely foaming the opening. We put on the sashes and let the foam dry.
We have presented the correct way to install a plastic window in a wooden house. This process can be difficult, so if you are unsure of your abilities, it is better to turn to professionals.
However, installing a plastic window with your own hands is a significant cost savings. We offer you to watch a video instruction for installing a window with your own hands:
Installing plastic windows in a wooden house: do-it-yourself installation video
Repair work in a wooden house differs significantly from similar buildings in a different form. Most companies do not provide a guarantee for installations carried out here, especially plastic windows. Isn't this a reason to think about DIY installation? Armed with a step-by-step video, you can achieve a high-quality result, significantly saving the family budget.
Features of installing a window system in a wooden house
There are many prejudices about wooden houses. The service life of PVC windows installed here depends entirely on the quality of the building itself and compliance with the technology of the installation process.
You can not start working with a window opening in a new wooden house right away. In order to avoid deformation in the future, it is recommended to wait some time for the structure to stand, the wood to dry out, excess moisture to evaporate from it, and the walls to become static. Thus, the chance of mowing the opening is minimized.
As a place for a window, do not choose the outer part of a wooden house. The opening can be in the center or closer to one of the corners, but not in contact with it.
The installation process itself is not too laborious: it can be carried out with one pair of hands in a few hours. The subtleties of the preparatory work depend on whether the windows have already been installed before or whether the casing needs to be created from scratch. A similar technology can be used to install PVC in any wooden building: a bathhouse, a gazebo, etc.
Preparing the Workspace
For hand-made installation of plastic windows, you need a reliable base - a frame. If the previous windows were installed within the last few years, did not have time to acquire physical damage and were not touched by rot, then you can use the box from them as a frame for the new system. With this option, measurements are made according to the new size of the opening, focusing on the preserved box.
If PVC is installed in a new building, then you will have to take care of the pigtail. This is the name of the design that prevents the window system from deformation. There are several types of it:
- With a mortgage bar;
- In the groove of a log wall;
- On a spike in the wall;
- With a quarter.
Using a rag, you can remove dirt, dust and start measuring. The reliability and expediency of carrying out all further work depends on their accuracy: inattention at this stage can jeopardize the entire installation.
Advice. If the opening is distorted, then to create a plan with measurements, they are guided by the supposedly correct geometric shape and right angles, and the deformations are removed with a sealant or ordinary putty.
Window sill installation and window preparation
The window sill is the basis of the entire window system, so its installation must be carried out with a level: the horizontal surface must be ideal from both the longitudinal and transverse positions.
To do the work with your own hands, the following algorithm of actions is used:
- Small recesses (at least 5 mm) are made in the window box for additional fixation of the window sill.
- Using plates made of fiberboard, plastic or wood treated with an antiseptic, level the level of the window sill.
- With the help of self-tapping screws, the installation of the window sill is carried out. A gasket or washer must be placed under the caps to prevent cracks. For self-tapping screws, you need to choose a place where they will be hidden by a future window. Usually, it is located at a distance of 2-4 cm from the end.
- After installing the window sill, its horizontalness is checked using the building level.
As for the window itself, it is necessary to attach the handle in the downward position (closed state) before installation.
Window installation
Installing a window in a prepared area of a wooden house is no different from installing it in another structure. The process is performed in the following sequence:
- Marking the window frame and drilling mounting holes. The procedure is performed using a 6 mm drill for the corresponding self-tapping screw 1 mm smaller in diameter.
- Installation of the system in the opening. At the same time, they are guided by the window sill, the even level of which, thanks to additional control, is beyond doubt. The center is determined using a centimeter tape.
- Level relative to the wall. To make the window parallel to the wall surface, use a plumb line. If it is trimmed with siding, which allows you to place a level between the trim and the wall, then you can use it.
- Fixing a bar that would completely fill the space between the window and its frame. It will become the focus for further installation. Installation without it may lead to overlapping of the window opening-closing mechanism.
- The window is fastened with self-tapping screws from the bottom and top of the side posts, so that they do not interfere with the free opening of the window in the box.
- Foaming of cracks and removal of its excess.
Installing a PVC window with your own hands can save up to 60% of the family budget. Following the detailed instructions for their installation will make the structure resistant to seasonal tree deformations, extending the life of the system for a long time.
Choosing the type of window to install in a wooden house is an important aspect in creating the overall design. But there are some nuances in this matter that you need to know before making the final choice. There are three types of house windows: aluminum, wood and plastic. Wood has been and remains the elite among materials, as the most environmentally friendly. The cost of double-glazed windows on aluminum profiles is more democratic, but deviations from the installation technology can lead to the accumulation of condensate on the frame of such a window, which later falls on the wooden covering of the walls of the building and can lead to mold and decay. The most economical option is to install plastic windows in a wooden house. Due to the low price, PVC windows are statistically leading in terms of the number of installations, but the question of their quality remains open.

Materials, dimensions and shape of the window
In the manufacture of wooden windows, the following materials are used:
- Pine- the most inexpensive type of wood. Of the advantages noted good moisture resistance. This is due to the high content of resins in pine. Of the minuses - low strength due to the softness of this type of tree species.
- Larch is the most durable representative of conifers. When in contact with water, it becomes even stronger, which is very important, given the operating conditions of windows. Given the excellent characteristics of moisture resistance, the cost of larch windows is not much more expensive than pine windows.
- Oak has the highest hardness and durability. The disadvantages include lower heat resistance compared to coniferous samples and a higher specific gravity. Oak windows are premium products and, accordingly, are more expensive than pine and larch windows.
Plastic and aluminum windows are made of profiles that are characterized by absolute moisture resistance.
The main standard for window size is the ratio: per 1 sq. m. glazing 10 sq. m. walls of the house. This ensures good illumination of the rooms. But you can deviate from this rule if the window is installed in the living room or nursery.

These spaces require more natural light. Recently, the so-called "Scandinavian" style of glazing at home has gained great popularity. Large double-glazed windows (6 sq.m.) provide a wonderful view from the window of a country cottage. But at the same time, the requirements for strength to the structural elements of the glazing are increasing.
An even more suitable option for lovers of large windows is the so-called panoramic glazing. Its area can reach up to 70% of the total wall area of the house. In this case, tempered glass or triplex is used as the material. This is far from the cheapest option, but windows made of such glass are much stronger and better withstand wind loads.
As a rule, the opening scheme of double-glazed windows are: rotary, sliding and tilt-and-turn mechanisms. Window shapes can vary from the familiar rectangular and square to the exotic triangular and trapezoidal. The most extravagant option can be a round and arched window. But they are extremely rare due to the complexity of manufacturing and installation.
Advantages and disadvantages of window materials
The main advantage of plastic windows in a wooden house is their low cost. In the presence of high-quality fittings, plastic and aluminum frames provide a good level of tightness, high heat and sound insulation.
To maintain the aesthetics of windows, it is enough to wash them in time. Source instazu.com
On our website you can find contacts of construction companies that offer window and door installation services. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".
An important factor is the ease of maintenance of double-glazed windows - in contrast to wooden ones, which require periodic preventive measures for treatment with protective agents.
Another advantage of plastic and aluminum windows is their high resistance to external factors - the sun or rain practically do not affect them.
The main disadvantage of double-glazed windows made of PVC and aluminum is the low maintainability of the profile. For example, glass replacement will require contacting a company that specializes in such repairs. In order to change the glass in a wooden window, specialized tools are not required and any carpenter will cope with the task.
Another disadvantage is that if non-premium profiles with special coatings were used for the window, then over time, minor defects in the form of scratches and chips may appear on the window sill and PVC window frame. This is due to the fact that plastic attracts dust more than wood and dirt particles gradually "break" the protective coating. Over time, these places begin to turn black from the dirt accumulating in them.
The main advantage of a wooden window is its “eliteness” and environmental friendliness. The disadvantages include insufficient moisture resistance and a shorter service life compared to plastic ones.

Pitfalls and their installation
The main feature of a wooden house is that it is constantly “in motion”. If this is a new house, then the first year or two there is a process of shrinkage. Then it is necessary to take into account the effect of expansion of the tree with changes in temperature and humidity. As a result, the walls of the house, although imperceptible to the eye, are moving, so it is impossible to rigidly fasten the window frame to the wall. If this is done, then at best it will lead to jamming of the shutters in the frame, and at worst - to the destruction of the glass in the package.
The way out is the manufacture of the so-called pigtail (casing) - an intermediate box, which can move slightly inside the wall along specially cut grooves. This allows you to maintain the integrity of the window during shrinkage of the wooden elements of the wall.
Pitfalls are of the following types:
- Simple. For its manufacture, grooves are cut out at the end of the opening and reinforced bars are inserted into them, which perceive the load from the components of the wall.
- Complex. It involves cutting a special ledge in the window opening. It serves as the basis for a prefabricated U-shaped bar. Due to the large area of contact of this beam with the wall elements, it is able to withstand a large load.
The main thing in the manufacture of all parts is accuracy, this will allow you to install the pigtail into the opening without any problems. Source indeco.ru
For the manufacture of casing, a chisel and a hand-held circular saw or a hacksaw are used, as well as a bar, the dimensions of which depend on the thickness of the wall of the house.
Using a cutting tool, the required length of the casing stand is cut off. In the prepared part, a groove is hollowed out with a chisel. In the counterpart of the opening, a protrusion is made using a saw. The stand is inserted into the opening. In this case, the groove is combined with the protrusion. This operation is performed on all sides of the opening.
Installation of windows in a wooden house
Installing a window in a wooden house begins with the manufacture of a window opening or the removal of an old double-glazed window (if we are talking about replacing a window).
In an old house, it is also necessary to inspect the opening itself. For example, in log houses, very often the lower part of the opening suffers from moisture. In this case, repair of the damaged area is required. If there is no need for repair, then the opening is cleaned of dirt, and measurements of the future window are made.

The whole process of installing a window in a wooden house, see the video:
Direct installation of a double-glazed window begins with detaching the sashes from the window frames (it is much more practical and simply more convenient to install the frame first, and then hang the sashes on it).
The frame is installed and fixed in the pigtail. This is done according to the level and plumb, so that the horizontal and vertical position is observed. When the frame is fixed in the box, sashes with double-glazed windows are hung on its hinges. After that, a window sill is installed, and the space between the pigtail and the frame is foamed for sealing.
As a result, a feature of installing windows in a wooden house is the mandatory preliminary manufacture of a pigtail. Otherwise, installation is carried out in the same way as in panel or brick houses.

Exterior window decoration in a wooden house
The main element of the window decor, first of all, are the platbands. The overall interior of the house largely depends on how they are selected. The platbands give the window a finished look, and in addition, they perform a protective function, closing the space between the frame and the opening from drafts, ultraviolet radiation and weather precipitation.
The standard choice of the color of the architraves is its correspondence to the color of the frame and the edging of the double-glazed window. However, an interesting solution may be the contrast between these components of the window. For example, the frame and edging are white, and the trim is dark.
Another option would be to install shutters. This will give originality to the house, as if you plunged into the former Russia of tsarist times. Especially this decor is suitable for a log cabin, not covered with anything from the outside.
Shutters can be made both in the classic version and finished with beautiful wood carvings Source homeinterior.pro
Shutters are easy to remove and install, which is why many use it to periodically update the appearance of the facade of the house. Several types of shutters are made - with different patterns or ornaments, and a new set is installed from time to time.
An interesting solution could be to install a small hanging flower bed under the window at the level of the windowsill, with various planted plants, ranging from flowers to exotic flora options.

Conclusion
Choosing and installing a window is a very important step in home improvement. It requires not only financial efforts, but also a creative approach to this matter. Since it is necessary to make a pigtail for windows in a wooden house, installation should definitely be entrusted to experienced professionals who know all the nuances of carpentry.
Installing windows in a wooden house is easier than in brick or concrete buildings. This operation has a number of features, which we will discuss below.
Preparatory procedures are half the battle. a lot will depend on them.
Dismantling of old frames
Before inserting windows in a wooden house, it is necessary to dismantle the old ones. If your house is new and there are no double-glazed windows at all, you can skip this paragraph. Most offices for the dismantling of old windows will take 50% of the cost of new ones. Therefore, to carry out this procedure independently is beneficial from an economic point of view. In addition, it does not require special skills.
Tip: old frames can be used for greenhouses or outbuildings.
Armed with a puller, a screwdriver and other tools, you will need to dismantle. We start with the sashes: open them, remove them from the hinges and pull them out. Next, remove the frames, window sill and other elements.
Creating a simple casing
If we are talking about an old building and such elements already exist, you can skip this paragraph. Before you install a window in a wooden house, you need to create a "casing". An okosyachka is a structure along the opening, which saves the frames from all kinds of damage. The beam (including the "round timber") begins to deform over time - this process is called shrinkage. So that it does not affect the brand new double-glazed window, and install this design.
It is created as follows:
- We cut out protrusions from a medium-sized timber (3 pieces - for each side of the opening). They will be needed to create carriages (side elements). The end bars should be set to a depth of 5 cm.
- At the ends of each of the elements we create grooves - for reliable fixation. So that they do not creak, we cover the structure with rolled tow. Such a measure will also increase the thermal insulation of the window.
- We get a U - shaped design. It must be mounted in the opening using large nails (200 mm) or special self-tapping screws.
There are other options for creating a pigtail, but this one is the simplest.
We prepare tools and materials
We will need the following:
- Powerful drill and screwdriver.
- Level (preferably laser).
- Chisel.
- Roulette.
- Gloves.
- Mounting foam (or similar material).
- Pliers.
- Spacer bars (you can do it yourself).
- anchor plates.
- Hexagon (it will be needed for finishing fittings).
- Anchor screws.
Main front of work
From preliminary procedures we pass to the final stages.
Measurements and design
Self-installation of PVC windows in a wooden house begins with measurements. You will need to do the following:
- Armed with a tape measure, measure all sides to the nearest millimeter.
- We draw on paper a project of the future window with the preservation of all proportions.
- We mark the places of separation, vents and other components that you want to see in your double-glazed window.
- With a ready-made plan in hand, you can contact a window manufacturing company.
Starting stage - window sill
Installation must begin with the window sill, as it is the basis of the entire structure. Install it like this:
- Two grooves with a depth of no more than 10 cm are cut from the side in the box. This will allow you to securely fix the window sill.
- We apply it and, if necessary, level it with wooden plates prepared earlier.
Tip: if you mount the window sill at the end, a gap will form, which will need to be repaired regularly. Installing it under the frame increases the efficiency of the design.
- Having achieved an even location, we fix the window sill with the help of self-tapping screws. Under the hat you need to put a rubber gasket - this will prevent possible cracking of the plastic.
- We drill holes where the window sill will cover the frame. They need to be done at low speeds so as not to damage the plastic. If you use a powerful drill, during drilling, it may begin to melt, so it is better to arm yourself with a screwdriver.
- Adjust the level. The window sill must be strictly horizontal!
Some manufacturers offer double-glazed windows without window sills (they are purchased separately and installed at the end). We advise you to purchase all the items at once from one seller - it's more reliable.
Preparing the ground for future work
Do not rush to remove the factory film - it will protect the structure from damage. We work in the following sequence:
- We take out the frames and install the handle. To do this, put it in a horizontal position, fix it with bolts and lower it down.
- We mark on the side racks the places for drilling the holes necessary for fixing the frames. Drill - 6 mm, respectively, self-tapping screw - 5 mm. On each side rack you need to make 2 holes (total - 4). They should be located at a distance of 30-40 cm from the lower and upper ends of the beam.
- In order for the self-tapping screw to securely rest on the frame, it is necessary to drown it. To do this, use a 10 mm drill to make holes to the iron frame. The cap should freely enter the cavity of the beam.
We mount a PVC window
The turn of the most crucial stage has come - the installation of frames. We put the finished structure in the opening. We adjust on both sides of the frame and control them with a tape measure and a level. The distance from the sash to the pigtail on both sides should be the same (within 1 cm). You also need to control the verticality of the installation. This can be done with a plumb line.
Having achieved an even position, we put a spacer bar between the box and the frame. It will act as a stop during installation - without it, when screwing in the screws, the frame can go to the side. Having installed the bars, once again carefully check the evenness of the location along the slope. After making sure that the window is perfectly horizontal (vertical), we fix the window with self-tapping screws. They should be located between the window and the box.
This method of installing the box is highly reliable and mobile - if the wood is deformed, the frame will not warp. This is achieved due to the fact that the self-tapping screws are able to go in the direction of skew.
- We insert the adjusting plates between the drain holes (they are needed to drain condensate - without them, the double-glazed window will inevitably fog up).
- We insert a double-glazed window into the opening. It should not stand tightly - this is due to seasonal deformations of wood and other materials.
Important! If you find that there is no standard gap (5-7 mm), contact the manufacturer, as this is an obvious defect.
- We evenly install the double-glazed window and fix it with the help of glazing beads (they should be included in the kit) with profile spikes. You need to tap on them until a characteristic click appears, signaling the correct insertion.
- All existing gaps are filled with mounting foam. After 2-3 hours, cut off the excess with a knife.
This completes the installation of windows in a wooden house with your own hands.
A few words about cash
First of all, it is needed to increase the insulating properties and hide flaws. It closes the foamed cracks, which completely prevents the possibility of cold air entering inside. There is a second function - aesthetic. Cashing windows in a wooden house favorably frames the opening, giving it an attractive appearance.
It can be made from various materials, most often plastic. These are ready-made structures that only need to be fixed with self-tapping screws along the perimeter of the window. However, carved cashing is sometimes performed for wooden houses. It can be made to order or independently, if a person has carpentry skills. After installation, the cashing is covered with an antiseptic and wood varnish - this will prolong its life.
