Reading time ≈ 6 minutes

Every builder knows how to install wooden windows in a wooden house, but ordinary residents of private houses cannot do this with their own hands. The reason is the lack of knowledge, although ordering such a procedure from experts will cost a pretty penny. Read the information below to make your home as comfortable and warm as possible.

Grandparents know perfectly well what a wooden frame is. After all, before such windows were on every corner. The process of installing a wooden window requires special skills and abilities from the master in order to get the right result. It is from the experience and skill of the master that the quality of installation, compliance with tightness, service life, and the appearance as a whole directly depend. And in order to avoid drafts and unnecessary distortions, let's look at the correct instructions for installing wooden windows step by step. When installing a wooden window, one cannot do without skill and certain skills, but then it will be possible to make an excellent glazed one.

Features of installation and dismantling of old wooden windows

Before installing wooden windows in a wooden house, you should listen to the recommendations of experienced craftsmen in order to effectively carry out the operation with your own hands. Especially if you have never experienced this kind of work before. It is best to transfer such a process into the hands of a master who knows all the secrets of installation firsthand. After all, the lack of necessary skills can lead to the fact that the frame will be damaged. And their cost is quite high, so spending extra money on repairs is expensive. In addition, repair is not always possible. However, it is often necessary to install products, for example, in.

Woodworking enthusiasts can delve into the details of the installation and try their hand at this craft. If you follow the recommendations, you will not only be able to install a wooden window with high quality, but also save a lot.

Tip: in the case of ordering a new wooden window, it is worth leaving the installation in the hands of the manufacturer. The fact is that in this way all guarantees for this design will be preserved. And if the installation is independent, then all your mistakes will remain on your conscience.

In any case, before installing new window frames, it is worth removing the old structures. This paragraph does not apply to houses that are under construction. By following the correct sequence of actions, you will greatly facilitate your task:

1. Before work, you need to prepare the room. If possible, it is better to move small interior details, clothes and furniture to another room. Thus, your things will be safe and sound.
2. The furniture that has remained in the room and the flooring should be secured. To do this, it is enough to cover them with a film.
3. Floor coverings should also be removed. This includes a carpet, carpet, path, etc.

After such preparations, you can proceed to the very dismantling of the old window. To do this, carefully, but applying force, you need to disassemble the wooden frame. At the same time, the slopes are beaten off along with the plaster. This operation will help you determine the presence of a lintel. Without this element, the structure is dangerous. In older buildings, such a "hack" is found all the time. If you are also included in this number of "lucky ones", then further actions are impossible without solving such an issue with professional builders, and you do not need to meddle there yourself. But experience will help you further develop in the direction, and then completely.

Then beat off the slopes in all places. Take a close look at each wall to see if there are embedded bars on which the window frame is fixed. It is worth immediately determining their condition.

Mortgage bars in the wall

Tip: In order to find out if these bars need to be replaced or not, use a regular awl. It is worth sticking it in a bar. If it sits tight and is difficult to pull out, then everything is in order. Their presence is not necessary to install a new window.

The importance of correct measurement of parameters

Replacing any window requires the correct measurement of parameters. This will determine how perfectly the window fits into the window opening. If you have a wooden house, then cleaning should take place to the level of the casing. Now you can start taking measurements. It is important to measure clearly and in the right places. Even a small mistake can cross out everything.

Even if you have saved previous measurements, it is not a fact that they will fit now. After all, over time, any building is influenced by external factors. It is important to create a wooden window slightly smaller than the opening itself. So you can correctly set the frame in relation to the horizon using the correction. To do this, subtract 15 - 25 mm from the height, and as much as 4 - 6 cm from the width indicator.

All parameters are taken from ideal lines (horizontal and vertical). To create them, use the building level. Modern devices, such as a laser tape measure, will greatly simplify all measurements. After all, it will give a real indicator for each parameter. It is also important to know how if they are located on the upper floors.

Wooden window installation step by step

Before you install a wooden frame, you need to prepare the necessary tools. For work you will need:

• drill and perforator;
• pliers with a hammer;
• screwdrivers;
• perhaps a saw and a planer with an axe.

It will not be superfluous to buy a sealant on silicone, mounting foam, roofing material (polyurethane). These materials are useful in order to seal the opening.

If a wooden window is installed in a wooden house, then the technology involves the use of support blocks.

Initially, the installation of wooden windows in a wooden house with your own hands begins with protecting the window from moisture, which can be provided by a wooden wall. After all, such moisture provokes the occurrence of mold and various fungal growths. And all this spoils the wood very quickly. Therefore, it is necessary to glue parts of the roofing material in the opening. It sits well on silicone. Here is what you should do:

1. Blocks (length 12 - 15 cm) made of wood. One end should already be under the frame. The widest point should correspond to the distance between the frame and the wall. You need at least 4 pieces.
2. 2 pieces are installed at the bottom of the opening. There should be about 80 cm between them (depending on the size of the wooden window).
3. Remove the sashes from your frame and place it in the opening itself on supports. Keep the required slope - at least 10 cm.

1. The remaining pads are set according to this scheme, as in the photo. They shouldn't be too tight, so use a planer to lighten them up if necessary. Constantly adhere to the vertical (plumb test) and horizontal (level test) so that there are not even small distortions.
2. When everything is set perfectly, you can pull out the block one at a time, fill this place with sealant and insert it back.
3. The hardest part is behind. Now it's up to the mounting foam. With its help, all the cracks around the perimeter are closed. You need to work with it carefully, and after drying, simply cut off the excess parts with a knife.

You can learn more about installing windows from the video. Now you know perfectly well how to install wooden windows in a wooden house, and you can do it yourself, and not spend extra money on the work of builders. The main thing is attention and patience.

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 performing the installation of plastic windows in a wooden house, you are guaranteed to receive window blocks that will last 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 window sill is installed strictly horizontally

The next step is to properly install the handle. The film that protects the structures should not be removed, it protects them from damage when 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.

In our time, with constantly rising prices for "life", all sorts of thoughts about keeping warm in our home visit our head. Everyone knows that metal-plastic windows retain about 25% of heat, which means that they will help us save a lot of money with the onset of cold weather.

Installing a plastic window in a wooden house is not a tricky business. Almost everyone will be able to do this, having in their assortment the usual tools found in every garage. Do-it-yourself installation will help save money and nerves, since workers in the house are not always good. Let's consider the process in more detail.

Choosing a plastic window for a wooden house

First of all, you will need to take accurate measurements of the window niche. Moreover, the accuracy should be up to a centimeter, without “approximately”. If the measurements are smaller, you will have to beat off the wall, if more, close up the space between the window frame and the wall. When installing PVC windows in a wooden house, the gap should be as small as possible. But it should be borne in mind that the tree tends to expand, absorbing moisture. Subsequently, the window opening can be deformed. After all the measurements are made and recorded on your sheet, we go to a specialized company for the manufacture of plastic windows.

When choosing a new window, you should focus on 4 components of the window:

Double glazing. Glass is the most important component of a modern window. About 65% of heat loss passes through it. The most popular double-glazed windows are double-glazed windows, in the chambers of which there is a gas that has a minimum thermal conductivity. Windows with additional film are now popular. The range includes transparent and opaque films. It additionally reduces the heat transfer through the double-glazed window. Windows with tinted film are best installed on the sunny side.

Profile. An important role in the structure of the plastic window is played by the profile. The characteristic of the profile is determined by the number of air chambers, which serve to reduce thermal conductivity. Their number significantly affects the thermal conductivity of the window. If your wooden house is located in a place with a high level of noise (for example, near a highway), then a six-chamber profile with double glazing will provide excellent sound insulation in the house.

Accessories. It must be made of high quality metal. The fittings endure considerable overloads, especially when the swing window mechanism with ventilation is used. The fittings are made of low-quality metal and will serve you for a short amount of time. With further long-term operation, such troubles as sash distortion, poor closing and leaks are possible.

Seals. Also, pay attention to seals. They must be made of a special material that remains elastic under any conditions, be it cold or hot. Ordinary rubber loses its elastic properties when the temperature drops, and with prolonged exposure, it cracks and crumbles.

All this should be considered before installing a plastic window in a wooden house. If you choose all these elements correctly, then your euro-window will not let you down and will keep your home warm. And remember that expensive is not always good. We must always choose the golden mean.

Removal of the old window and preparatory work

It is better to do it slowly, but first-class. Specialized workers do everything quickly, but they do not bother with the quality of the dismantling. Very often, they leave broken walls, broken old frames and glass.

Performing all the work on installing windows in a wooden house, there is no need to rush. You can make everything much neater, leaving all the elements safe and recyclable. They will also come in handy for a summer house or garage.

We remove the old window in the following sequence:

1) Remove the sashes.
2) Pull out the frame.
3) Remove the window sill and ebb.

Production of window casing in a wooden frame

This step can be skipped, but serious problems can arise in the future. The casing will prevent the window opening from being skewed. The material must be dry and durable, the thickness of the board is more than 4 cm. Otherwise, they will deform along with the opening. The width of the casing must match the thickness of the wall.
Casing methods:

• Spike-monolith.
• Underlay beam.
• Into the deck.

The most difficult and reliable is the first type of casing. But beginners who do not have special skills in installing windows prefer to do casing with a backing bar. This requires making furrows in the middle of the window opening.

You will need a circular saw, an axe, a chainsaw or a chisel. The optimal size of the furrow is 5x5 cm. An edged board is laid on a bar of the same size and fastened with self-tapping screws or bolts. If tenon-groove casing is used, then the T-bar is cut out in advance and inserted into the furrow. The final stage is considered to be laying the gap between the casing and the wall with mounting foam. Since the foam tends to break down under the action of sunlight, it is necessary to close the foam with a windproof membrane from the outside, and a vapor barrier inside.

Installing a window frame in a house

Before the final fastening of the frame, first of all, it is necessary to try on the base in the window opening. If it is inconvenient to use the building level, you can use a plumb line. Then, with the help of wedge-shaped blocks, we fix the frame in the window box. This will help prevent the frame from moving horizontally, and will facilitate further final fastening.

For the correct installation of windows in a wooden house with your own hands, it is worth installing fasteners. The gaps between the frame and the opening should be within 1 cm. Most often, anchor plates are used. They are attached to the box with self-tapping screws, about 3 - 5 cm long. At the end of all installation work, the gap between the frame and the window box should be filled with mounting foam. If the gap is more than 2 cm, then foaming should be divided into several stages. Drying time of the foam - 10 - 12 hours.

Installation of window sashes in the house

After mounting the frame, install the sash. The leaf is a mobile component of an eurowindow thanks to what its opening or closing is made. It is fixed on special articulated-movable elements (loops) of the frame.

If the frame is set correctly and level, the sashes will fit perfectly. However, there may be nuances with gaps and locks. They can be adjusted with a Phillips screwdriver. The basic rule for mounting sashes is to do everything evenly. If the side needs to be raised / lowered, then turn the bolts an equal number of turns. After each manipulation, you need to open / close the sash, try on the changes.

Installation of fittings, slopes, window sills in a wooden house

The frame was placed, the sashes were screwed on and the mounting materials were allowed to harden a little. Now we have come to the final stages of the instructions for installing windows in a wooden house with our own hands. It remains to finish some touches and you can celebrate the victory.
First, you need to choose and install the right window sill. There are several common types of window sills.

• Plastic. Very light and relatively durable multi-chamber type of window sills, which are covered with PVC film on top. There are many colors and imitations of various materials. But consumers prefer the standard white or woodgrain color.
• Wooden. Wooden window sills react to moisture changes and as a result can be deformed. The advantage of wooden window sills is naturalness and appearance. At the same time - a coating with a special protective layer is required!

Consider how to properly install a wooden window sill in a log house.

Step 1. Processing materials. To begin with, it is necessary to treat our window sill well with a moisture-proof composition that will protect it from premature rot and damage to the window sill. The window opening must be cleaned of dust and mud deposits, and, if possible, treated with the same composition as the window sill.

Step 2. Installing the window sill. The wooden window sill is attached to nails, which must first be hammered into the lower beam of the box. After leveling the window sill, using wedge blocks, tighten the screws from the front side of the window sill until it stops. All voids that remain should be sealed with foam. After drying, cut off the excess.

Carefully choose a tree for making a window sill. It should not be overdried and have chips and cracks. Wooden window sills are well suited for any log house. And also serve as a good shelf for various plants or small things.

After the complete installation of the window sill, we proceed to the installation of wooden slopes. The process of installing window slopes from the inside is completely identical to installing slopes from the outside, and will not cause any problems during the work.

This is the final chord in installing windows in an old wooden house. Let's consider all the processes step by step.

Step 1: Sidebars. First, we fix the side panels with self-tapping screws. It is advisable to place the attachment points of the panels where the decorative corner will be installed, which will cover all the screws. So we will keep the aesthetic appearance of the panels to the maximum. Then, by the same analogy, we finish the upper window opening.

Step 2. Sealing the seams. We coat all seams and joints of panels with sealant to prevent moisture penetration. Additionally, it can be treated with a moisture barrier.

Step 3. Mounting the corners. After all the seams and joints have dried, we install the decorative corners. They can be attached with liquid nails, a construction stapler or foam. All work on the installation of the window sill and slopes should be carried out after the structure has completely dried. This means that you must wait at least 12 hours after installing the window.

If you are installing for the first time, the process may seem quite complicated. It is better to immediately watch a video on how to install plastic windows in a wooden house. The main feature of wooden structures is their environmental friendliness. A wooden beam has the ability to "breathe", grow old and shrink. This is the main reason that makes it difficult to install windows and doors in a wooden frame.

Shrinkage occurs due to the loss of moisture from the wood. This is especially noticeable in the first 4 years. Mounting foam is what we need to compensate for minimal shrinkage. Making the casing, we make the window opening independent of the walls. The pigtail limits the vertical movement of the log, thereby ensuring normal, uniform shrinkage and does not prevent the log from breathing.

So we figured out how to properly install a window in a wooden house. There is nothing difficult in this. Everything is elementary simple and clear, if you perform all installation work using proven technologies and simple step-by-step instructions.

How to fix a window: an overview of fasteners and a photo report on the installation

Hello. In this article, I will talk about how to fix plastic windows in a residential building with your own hands using an available tool. I hope that this topic will be of interest to you, as installation skills can save money.

Despite the fact that for many manufacturers the price of windows includes the cost of installation, there are many companies where they will sell you a double-glazed window cheaper due to self-assembly. Saving money is obvious!

Basic information about window installation

Installation of glazing in the opening differs depending on the type of profile used and depending on the type of walls. For example, installation in a stone, concrete or brick wall is carried out directly without any structures that compensate for the mechanical loads on the window.

At the same time, installation in a wooden house is carried out with the obligatory device of a casing box, which compensates for loads due to shrinkage processes.

There are two main requirements for the installation of plastic double-glazed windows:

• Strength and reliability of the installed glazing;
• Correct location in terms of level relative to the vertical and horizontal plane;
• Properly executed sealing of gaps along the perimeter of the opening to ensure optimal energy efficiency of the glazing.

Fasteners for installation of double-glazed windows in PVC profile

Commonly used fasteners for plastic windows: a - frame dowel with a metal seal; b - frame dowel with plastic seal; c - universal plastic dowel; g - screw (self-tapping screw); e - anchor plate

Before proceeding to the description of the installation, I propose to find out what fasteners for PVC windows can be purchased at hardware stores. There are many fasteners and such a variety is not accidental, since each variety is intended for one or another type of wall.

Window fasteners, according to the type of walls, are divided into the following categories:

• for concrete walls;
• for the installation of brick walls;
• for installation in aerated concrete walls;
• for fastening to wood.

By the way, with the use of the listed fasteners, a protective grille can be installed.

Fasteners for installation in concrete openings

Plastic double-glazed windows are installed in concrete openings by means of anchors or, as they are also called, frame dowels.

For reliable fixation of a heavy window in a concrete opening, it is customary to use anchors with a diameter of 8 or 10 mm and a length of 72 to 202 mm. The length and diameter of the hardware are selected taking into account the density of the wall - the more porous the concrete, the longer and thicker the anchor.

No matter how long and thick the anchors are, the strength of the finished result will depend on how carefully the hole is drilled. If the walls of the hole are broken as a result of unprofessional drilling, even the most reliable fasteners will not provide the necessary mounting strength.

Installation with anchors is carried out in two ways:

1. A hole is drilled in the profile and the anchor enters the concrete directly through the profile;
2. An anchor plate is attached to the profile and through the plate the window structure is fastened to the opening.

The first method is relevant if the technological gap between the profile and the gap is small. If the distance between the profile and the opening is more than 1 cm, an anchor plate can be used, since the fasteners can be covered during finishing if plastic slopes are used.

Anchor plates are metal strips of a simple or complex configuration. Plain plates are ordinary perforated strips. Along with such devices, there are “crabs” - plates that cut into the profile, which simplifies the finishing of slopes.

Fasteners for installation in brick walls

The fastening of plastic windows in a brick opening is carried out in approximately the same way as in. But there is one problem: if for installation in concrete, holes for the anchor in the profile can be drilled in advance, then in the case of brick walls, the holes are drilled in place, since you need to get into the center of the brick, and not into the masonry seam.

For installation in brick, the same frame dowel is used as for concrete walls, but with a length of at least 10 cm. A length of 10 cm is the minimum entry into the brick at which you can be sure that the fastening will not loosen or weaken when operation.

If you are sure that the brick is not hollow, and today this is rarely used, you can use dowels 6-8 cm long.

Fasteners for installation in wooden openings

The best option for installing windows in a wooden opening without a casing is self-tapping screws in combination with anchor plates. This type of fastening is equally good for log, lumber and frame buildings.

If a casing box is installed in the opening, installation can be done with screws directly through the profile. To install glazing in a wooden opening, I recommend using self-tapping screws with a length of at least 10 cm and a diameter of 8 mm. We screw in the screws in increments of 30 cm.

Fasteners for installation in aerated concrete openings

Aerated concrete blocks are characterized by low density, and therefore we choose special dowels for installation and perform installation with a small pitch between the screws.

The installation of glazing in aerated concrete walls requires detailed consideration, as more and more houses are being built using such blocks. That is why, in order to get acquainted with the installation technology, I offer a small photo report on the installation work done.

Installation of a plastic window in the walls of aerated concrete blocks

To perform installation work you will need:

• Perforated anchor plates (160×40 mm and 2 mm thick);
• Plastic dowels (50×10 mm) for mounting in aerated concrete;
• Universal metal self-tapping screws (60×6 mm);
• Electric drill and drills in accordance with the diameter of the dowel;
• Screwdriver with a set of bits;
• water level;
• Roulette and pencil.

Installation instructions are as follows:

• If the perforation in the anchor plates does not match the diameter of the dowels, we drill holes, if the diameter initially matches, skip this step and proceed to the next one;

• Along the perimeter of the profile, we fasten the anchor plates to the self-tapping screws so that the holes drilled for the dowels are located outside;

In order for the frame to be securely fixed in the opening, we mount the anchor plates on 2 self-tapping screws, which will prevent them from turning. In addition, the installation step should not exceed 30-40 cm.

• We install the frame in the opening on plastic inserts and position it according to the level in the horizontal and vertical plane;

• After the structure is aligned in the opening, we drill holes in the aerated concrete blocks in accordance with the perforation in the anchor plates;

For drilling aerated concrete blocks, it is not necessary to use a drill with a winning surfacing. Since aerated concrete is soft, it is quite possible to use the same drill that was previously used to drill out anchor plates. By the way, when drilling, we try not to pull the drill from side to side, since breaking a hole in aerated concrete is easier than ever, and as a result, the dowel will not stick to the wall.

• We screw dowels into the drilled holes;

• We screw self-tapping screws into the screwed dowels;

At the end of the installation work, we do not remove the liners from under the window, as they will provide additional stability to the structure.

• From the spray gun, we abundantly moisten the technological gap between the opening and the profile;
• We fill the technological gap around the entire perimeter with mounting foam, so that the excess applied foam comes out from the outside and the gap is completely filled;
• After the foam has dried, the excess is cut off with a mounting knife on both sides of the profile.

By the way, how to attach a thermometer on the window and at the same time not make holes in the profile in vain?

It turns out that there is nothing complicated, just buy a special thermometer with Velcro on the glass. Thermometers with ears and mounting holes should not be mounted on plastic, but on wooden frames. But, if there is a thermometer with holes for screws, fix this device on the profile with short self-tapping screws - this will not harm the profile.

In conclusion, I note that if you don’t know how to fix the handle on the profile, you can also use small self-tapping screws that will go through the PVC and will be held in the metal.

Output

Now you know how to install a PVC window block in an opening of walls of different composition. I hope that the suggested instructions were useful to you. If you have any questions, as usual, ask them in the comments to the text. Also, don't forget to watch the video in this article.

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.

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.

Casing can be designed and installed at any period of building construction and its shrinkage. But without it, installing PVC windows is not recommended at all.

Features of work performance

When replacing old windows with new ones made of plastic, follow the procedure:

1. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Sealing tape is used to isolate the mounting joints between the frame and the walls.
7. 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.
8. 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.

Regardless of the method, checking the status of the pigtail is required., its replacement if any flaws or malfunctions are found. This operation guarantees the reliability and durability of the new PVC double-glazed window.

With original hole size

In the case of such a replacement method, several operations must be performed:

1. Dismantling of the wooden structure.
2. Check for the integrity, strength of the casing, the presence of additional fasteners on it that need to be removed.
3. If the pigtail has chips, damage, signs of decay development and other significant defects, it must be removed and replaced with a new design.
4. Measures are taken for the casing (in case of its replacement) and / or a plastic bag.
5. Glass preparation. Installing a pigtail or cleaning an old one, installing a window frame.
6. Fixing the window frame in the casing, then installing the sash on it.
7. Placement in the frame of double-glazed windows, fixing all additional elements.
8. 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:

1. The old design with a pigtail is removed.
2. A preliminary markup is made with a building level.
3. With a chainsaw or ordinary carpentry tool, a wider and / or higher opening is cut.
4. The size of the new casing is calculated.
5. A pigtail is being constructed, placed in the opening.
6. 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.

When calculating the format of a new window frame, take into account:

• 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.
