How to install a window in an opening. How to install plastic windows correctly

Technology for installing plastic windows in brick house differs from the rules for installing PVC profile products in concrete or panel walls. Important before you start installation work understand these differences and avoid mistakes.

Installation of plastic windows requires a set of tools and consumables.
Plastic windows in a brick house can be installed on anchor plates or bolts. Their size depends on the depth of the quarters into which the product will be attached, as well as the quality of the brick from which the walls are laid. It can be gas silicate, foam concrete, etc.

If the installation is carried out in a secondary housing stock, before installing the window, you must first remove the old frame from the opening. To do this you will need:

• removing the sashes from their hinges;
• deleting the old one;
• dismantling the window sill and ebb;
• removal of roofing felt and tow, once used to insulate the opening;
• chipping old plaster if it is necessary to align the geometry of the opening.

To dismantle you will need a small crowbar. If the frames are quite massive, then to facilitate the breaking process you can use hand saw woodworking or jigsaw.
To drill holes for fasteners, you will need a hammer drill, and to attach the frame to anchors, you will need a screwdriver. You will also need a construction knife with replaceable blades, a level, good quality construction guns for foam and sealant.

What materials are needed to install a plastic window?

Installing plastic windows is a multi-stage process. At each stage it is necessary to use various consumables:

• mounting wedges;
• professional foam;
• PSUL or acrylic sealant;
• water vapor barrier tapes;
• anchor plates or bolts.
• cyacrine;
• sealant.

Mounting wedges are needed to level the level; if necessary, they are placed under the stand profile.
Polyurethane foam- insulating material for filling the installation seam, i.e.

space between the wall and the window frame. Professional pistol foam must meet temperature conditions season in which installation is planned plastic window.
PSUL (pre-compressed self-expanding sealing tape) is glued around the perimeter window box and expands on the street side of the seam - from the edge of the frame in a quarter. By appearance resembles gray foam rubber. If there are no quarters, you will need a special acrylic sealant.
Waterproofing tape made of membrane material placed under the ebb for ventilation and protection of the bottom seam from moisture.
Sealant is necessary to fill the seams where the window sill joins the slopes and the window frame.

How to attach a window to an opening?

The rules for installing plastic windows are explained in detail by GOST R 52749-2007 “Window installation seams with vapor-permeable self-expanding tapes. Specifications" This state standard prescribes that before you begin installing a window in an opening, stick PSUL around its perimeter.
This self-expanding material is an independent installation layer that cannot be covered with plaster, putty, or paint over. Otherwise, the insulating material will not perform its functions.
When inserting a frame into a window opening, you should adhere to the tolerances. The deviation of the window frame in the horizontal and vertical plane should be no more than 1.5 mm per 1 m of length, but no more than 3 mm over the entire height of the window.

The frame is attached to brick wall according to the following rules:

• from internal corner the vertical distance between the frame and the first fastening element should not exceed 150-180 mm;
• from the impost to the horizontal fasteners, this distance is recommended to be 120-180 mm;
• vertical placement of anchors - with a gap of 700 mm for windows made of white plastic and 600 mm for laminated profiles.
  

  The inserted block must be checked for deviation from the level and foamed around the perimeter.

Assembly seam construction

PSUL around the perimeter and foam insulation are only 2 parts of the three-layer filling of the installation seam described by GOST.
After foaming the frame, it is necessary to remove the installation mounting wedges from under the stand profile and fill the resulting voids with foam. For better adhesion, the inner surface of the window opening can be moistened with a spray before foaming.
Before installing the low tide outside a waterproof, vapor-permeable tape should be applied. The ebb is screwed to the stand profile with self-tapping screws. The edges of the ebb must be bent to external slopes to avoid moisture getting under it.
A vapor barrier is glued to the inside of the window around the perimeter (except for the lower horizontal part of the frame), which provides an additional sealing layer to the installation seam and insulates it from moisture. This tape is available in various widths and can be applied both under wet finishing of slopes (plaster) and dry finishing (slopes made of polystyrene foam or plastic). They also produce universal tapes for slopes.
A vapor barrier is also installed under the window sill board: full-butyl tape with a foil layer.

Assembling the installed window

The frame installed in the opening and foamed around the perimeter must be assembled.

Double-glazed windows are inserted into blind, non-opening parts. To glaze (fasten) installed double glazed window, you will need a medium sized Plexiglas hammer. The beads are cut at an angle of 45° and inserted into the frame around the perimeter of the glass unit with some force. In order for the glazing bead to finally snap into place, it must be lightly knocked down with a hammer.
If installed window unit has opening doors, you need to hang them on hinges. This task is not difficult to cope with, since modern window fittings are very easy to use.
But putting the sash in place is not enough. You should check its functionality and, if necessary, adjust it in the hinge part using a special adjusting key.

To check how accurately a plastic window is level, you need to open the sash. If it does not slam shut or open wider by inertia, it means the block is installed correctly.

Installing the window sill and slopes

The installation of wooden windows, like plastic ones, cannot be considered complete if the window sill is not installed. The window sill board snaps into place and is attached to the stand profile.
If, during dismantling, voids are identified under the window, you can fill them with insulation, for example, rolled or tiled, and then install a window sill.
To finalize the opening, you need to understand how to properly install the slopes. They can be plastered or assembled from sandwich panels made of expanded polystyrene foam.
With the latter option, the panels are cut to size locally, taking into account the geometry of each slope. A U-shaped plastic profile, otherwise called starting. A panel is inserted into it. The voids foam.
Foam is a sealant made of polyurethane foam, which, due to its properties, requires certain time for complete expansion and hardening. Typically from 1 to 24 hours.
Sandwich panels are closed where they meet the wall decorative profile, most often F-shaped.

The junctions of the slopes and the frame to the window sill are sealed with sealant.

Who should you trust to install the window?

Installing a PVC profile window and installing a wooden window are not the same thing. Installing windows in a brick house involves certain nuances. You need to have all the necessary tools on hand, including adjusting wrenches for window fittings, as well as a supply of fasteners and special mounting tapes.

It is equally important to choose the right mounting foam and sealant. As an alternative to the latter, so-called liquid plastic can be used. This is a special adhesive-sealant that hardens very quickly, but also creates a particularly strong sealed seam.

If you are not sure that you can handle the installation yourself, it is better to seek the help of specialists.

Plastic windows deservedly enjoy a reputation for functional, reliable, durable and aesthetic designs. They are becoming more and more popular and are confidently replacing the ones that are familiar to many people. wooden windows.

Plastic windows have gained a reputation as strong, durable and reliable structures.

To their additional benefits It can be attributed to the fact that, with a strong desire, almost anyone can install plastic windows on their own. And this is a big plus, because... For installation, specialists ask quite a lot of money. In addition, having figured out how to install a plastic window, you will independently control the entire process and will be able to do everything in accordance with technology.

How to determine the size of a future plastic window

Before ordering plastic windows, you need to figure out what exactly the design should be. And this preparatory stage begins with taking measurements. At independent execution measurements House master should know that there are window openings without a quarter and with it. The procedure for measuring the openings of two different types will also vary.

The quarter option involves taking measurements in the following order. First you need to measure the opening between the quarters at the narrowest point and add 3-4 cm to the resulting value. This will be the width of the structure. Additionally, make sure that the specified width of the future plastic window exceeds the largest distance between the vertical quarters. To determine the height of the future window, measure the distance between the bottom plane of the opening and the top horizontal quarter. This way you will determine the amount you need.

In the case when a plastic window is installed in an opening without the above-mentioned quarter, to determine the appropriate size, you simply need to subtract 5 cm from the height, and 3 cm from the width.

Additionally, determine what size the window sill and flashing should be if you plan to replace them. There should be no complications with this operation, you just need to consider the following important factors.

When determining the width of the ebb, future thermal insulation or cladding must be taken into account. According to standards, the ebb should protrude from the vertical wall by 5-10 cm. The width of the window sill is calculated taking into account its future functional purpose. For example, if you want to install potted flowers on it, it is better to order a wider design. In most cases, when selecting a window sill, the calculation is carried out so that the free part of this element covers the heating radiators.

The length of the window sill should be 8-10 cm greater than the width of the opening. The edges must be recessed into the slope cavity by at least 5 cm.

Ordering a window and preparing for work

On next stage It is necessary to send the obtained measurements to a company specializing in the production of plastic windows. By the way, if you don’t want to waste time on measurements or doubt that you can do everything correctly, order this service from the same company. Most companies offer it free of charge, provided that the window is ordered from them.

In addition to the window size, you need to determine following parameters:

1. The number of cameras in a double-glazed window.
2. Number of cameras in the window profile.
3. Availability of fittings and necessary fasteners.

The consultant will tell you in detail about the features of each option. You can prepare in advance. So, if winters in your region are not very cold, and the street outside the window is not very noisy, a window with two glasses and a profile 60 mm wide will be quite sufficient. Next, focus on the climate and environment.

For self-installation plastic window you will need the following:

To install windows you will need: a hammer, a drill, a screwdriver, building level etc.

1. A gun for polyurethane foam and the foam itself.
2. Drill with variable speed control and perforation mode.
3. Small ax and hammer.
4. Metal scissors.
5. A sharp knife, a stationery knife will do.
6. Building level.
7. Chisel.
8. Sander.
9. Nail puller.
10. Jigsaw. If you don't have one, you can use a hacksaw with fine teeth.
11. Putty knife.

Additional materials you can buy:

1. Multi-purpose construction adhesive.
2. Wooden beam with a total length of 150-200 cm and dimensions of 2x4 cm.
3. Dowels.
4. Plastic corners and panels made of the same material.
5. Self-tapping screws different sizes. Typically used are 6x40, 2x16, 2x80.
6. Solvents.
7. Mix for plaster.
8. Silicate glue.

Do-it-yourself dismantling of an old window

At the very initial stage of changing windows, it is necessary to dismantle the old window design.

If there are already windows installed in the room, then before you begin installing a new window, you need to get rid of the existing structure. If you don’t plan to install the old window anywhere in the future, you don’t have to try to be careful, but caution won’t hurt. Do everything possible to avoid getting hurt or dropping the window outside. The last rule is especially relevant for apartments in multi-storey buildings, because a window could fall on someone or damage someone else's property. And even in a private house, cleaning glass will not give you any pleasure.

First, remove the opening windows and sashes. Remove all glass from the structure, first removing the retaining beads. Take a grinder with a concrete wheel or a hacksaw. Using the tool, make cuts along horizontal and vertical elements window frame.

Using available tools - a pry bar, a crowbar, or a hammer - remove the product from the opening. In some cases, when the owner wants to preserve the old window, the structure can be removed without deformation or damage. But this will require much more time and certain skills.

At this stage, both the external ebb and the window sill are dismantled. At the end, the window opening is thoroughly cleaned of dust and all kinds of construction waste.

Step-by-step instructions for installing a plastic window

Gradually you have come to the main stage of the work - installing a new window. This work requires careful and consistent implementation of a whole list of various activities.

First, the window is prepared for further installation. At this stage, you need to attach mounting plates to the end of the top and sides of the frame. In the future, it is thanks to them that the structure will be held in the required position. Quite often, installers replace plates with hangers, which are usually used when installing various plasterboard structures. But when installing a plastic window, it is much more advisable to use plates. They are stronger than pendants.

The planks must be securely fixed to the end of the frame. When installing, the fasteners will need to fit into the body metal profile block. And this should be done in such a way that the glass unit does not deform. Fastening is done using self-tapping screws. Select the diameter of these products taking into account the size of the window. Standard-sized structures are usually installed using self-tapping screws with a diameter of 4 mm. For larger blocks (from 2x2 m), it is best to use larger self-tapping screws - 5-6 mm in diameter.

Attaching the anchor strips to the end of the frame should be done so that they are installed in increments of 6-8 cm at a distance of 10-15 cm from the corners of the product.

After this, you need to correctly position the prepared window structure. At a superficial glance, this procedure may seem quite simple, but take it seriously. It is best to enlist the help of an assistant at this stage. One of you will support the block, and the other will level it.

Place the block in the opening and adjust its position using pre-prepared wedges. It is important to position the block strictly vertically and horizontally. At this stage, follow the recommendations:

1. Wedge the module not only from below, but also from the sides.
2. Make sure that all vertical frame elements are in the same plane.
3. If there is an impost, place wedges under it as well.

Check that the unit is installed evenly using a level. If there are the slightest deviations, correct them. And only after that proceed to fixing the module. To do this, use anchor bolts or dowels to fix the anchor plates to the opening cavity. It is important that the elements are attached strictly to the enclosing structures. To do this, it may be necessary to remove a layer of plaster where the anchor plates are attached.

After you securely fix the module, seal the seams using foam specially designed for this job. It is important that the material is intended specifically for the installation of plastic windows. Carefully read the instructions and make sure that it can be used at the humidity and temperature where the module is installed.

Before applying foam, moisten the joint surface with water. If you need to fill an area wider than 3 cm, do it in 2 stages with a half-hour break.

Relatively recently, all residential buildings had ordinary wooden windows, which had to be sealed for the winter. Today it is almost a relic of the past. And most people strive to replace such windows with modern plastic window structures, and they are especially interested in installing plastic windows with their own hands.

This desire of the consumer is quite understandable - plastic windows not only have an aesthetic appearance, but also serve as interior decoration. They are also much easier to use, last an order of magnitude longer, and are significantly cheaper than their wooden counterparts.

If you have a desire to replace the old windows in your apartment with modern double-glazed windows, then you will certainly ask yourself whether it is possible to install a plastic window yourself. How difficult is it to install plastic windows, and can you do it yourself without the help of specialists?

Yes, it's quite possible. In order to install a plastic window with your own hands, it is not necessary to have a construction specialty. With certain skills and good tools Anyone can install a plastic window with their own hands.

Let's figure out how to do it right.

What does a plastic window consist of?

First, let's look at the design of a plastic window. Without this, you will not understand the installation process itself.

Plastic windows are made from special material, which is called PolyVinyl Chloride. That’s why plastic windows are called PVC windows in short. Like any window, the main element of a PVC window is a frame made of a profile consisting of cells. The more such cells in the frame (also called chambers), the warmer the window will be.

Typically the frame color is white. Although plastic can be black, brown, and even colored. The most common and most a budget option– white plastic windows.

In addition, the window consists of an opening part (sash) and a stationary part, which is called a “capercaillie”. The glass unit is directly inserted into these parts of the window, which is pressed against the frame with a special plastic strip. For tightness, a black rubber seal is placed.

Installed on window sashes special mechanisms, with the help of which the window opens and closes.

In addition, on the outside the window has a so-called ebb - a small board with the help of which precipitation is removed, and slopes - plates that seal the side and top parts from the street side.

Stages of installing plastic windows with your own hands

All stages of installing plastic windows with your own hands come down to the following:

• careful measurements;
• dismantling old window structures;
• preparation of window openings;
• DIY PVC window installation.

Taking measurements

Before ordering and, accordingly, installing a plastic window, you need to make several measurements. Moreover, how carefully they are done will determine how your structure will fit into the window opening. Remember that accurate measurements are almost half the battle. If you take the measurements incorrectly, when installing plastic windows yourself, the structure simply will not fit into the opening. In addition, the windows may begin to freeze.

First you need to carefully examine the opening. If the part of the window that is smaller on the outside, then measurements are taken at the narrowest point. Moreover, it is highly advisable to make several of them, because window openings are rarely perfectly smooth. Find the smallest measurement value and add 3 to it. Measure the height, leave its value as it is.

If the window is the same size both inside and outside, measurements are taken slightly differently. You need to measure the width and height. Then you need to subtract 5 cm from the height, and 3 from the width. This will be the full size of your window, with width and height. We subtract the values ​​in order to leave gaps for installing the window sill and special mounting foam.

Each owner chooses the window sill according to the size he wants. Some like wide window sills, some like narrow ones, and some make them at wall level. This is individual, and there are no rules here. This applies to width.

The length of both the window sill and the ebb should be taken with a margin - about 10 cm wider than the window opening.

Getting ready for installation

Do-it-yourself installation of plastic windows always begins with dismantling the old window. As a rule, even novice builders find dismantling particularly easy.

After you have broken out the old window, you need to carefully inspect the opening and remove anything that may fall off later. If some parts of the opening protrude from the walls after dismantling, they must also be removed and the surfaces smoothed. Potholes, if any. It should be sealed with cement mortar.

When installing PVC windows with your own hands, you must take into account the following circumstances:

• the plastic window structure should be carefully secured;
• the window structure must be leveled both horizontally and vertically, otherwise in the future it may simply warp;
• It is necessary to plaster the mounting foam on all sides, with which the structure is attached, also in order to avoid future problems such as deformation.

Plastic window installation technology

Install a plastic window with your own hands as follows:

• The structure should be fixed on four sides using wedges, and it should be determined how accurately the frame is positioned relative to the opening;
• secure the frame with special bolts;
• attach the structure with screws to the wooden part;
• seal the plastic structure using polyurethane foam, spreading it over a surface slightly moistened with water.

We need to start with the fact that there are two different ways DIY installation of plastic windows.

The first method is to drill holes in the window frame for special anchors, which are driven into the wall. This is a rather complicated method, but a more reliable fastening.

The second method is that metal plates are first attached to the frame from the outside, and only then these plates are attached to the walls. It is much simpler and quick way, however, such fastening is not reliable. The frame can simply warp even in strong winds. Therefore, if you nevertheless decide to make your life easier and install a plastic window with your own hands using the second method, use thick and wide metal plates. In this case, you can give your plastic construction greater reliability. However, if your city is very windy, this method is definitely not suitable for you.

Direct installation

Installing a plastic window with your own hands using the first method with reliable fastening is carried out as follows.

First, you should check whether the structure and the window opening are compatible. If everything is in order, we proceed directly to installation.

First you need to remove the window sash. For this:

• turn the window handle down, placing the window in the “closed” position, and use a screwdriver to remove the trim from the hinges;
• pull out the pin, which is located on the top hinge;
• open the shutter by turning the window handle to a horizontal position, then lifting window sash, you can easily remove it from the lower pin.

After you have removed the sash, you need to remove the double-glazed window on the capecaillie. For this:

• insert a small spatula or something similar, strong enough, thin and not wide, into the gap between the frame and the bead;
• move the glazing bead with a spatula, going along the entire length, and remove it from the frame.

After this, you can easily remove the glass unit itself. The main thing is that it does not fall out of the frame after the glazing beads you removed are no longer holding it. To avoid this, the window should be tilted.

The frame is freed from the glass unit, and now it should be covered around the perimeter with special tape. This tape is needed to keep the window warm.

As a rule, white self-adhesive protective tapes are glued to the frames. It is also advisable to remove them, because later, when they heat up in the sun and stick to the frame, fused with it, this will be difficult to do. In the meantime, the tapes are very easy to remove.

Now the frame needs to be inserted into the window opening. To do this, you will need mounting wedges, which are placed in the corners (this is a mandatory requirement), as well as in other places where you deem it necessary.

Using a drill and a drill bit, special holes are made into which the fasteners are inserted. The first hole is drilled at a distance of 1.5 - 2 cm from the top edge. The bottom hole should be approximately the same distance from bottom corner. The gap between two fasteners should not be more than 5-7 cm.
The anchor is hammered into the hole and then tightened. At the same time, you must tighten the anchor carefully, trying not to overtighten, otherwise the profile will bend, and this cannot be allowed. This operation - tightening the anchors - is continued as many times as necessary.

After this, ebb tides should be installed outside. Before installation, self-adhesive waterproofing should be applied to the part of the frame that is located outside. Grooves are made in the side openings (the edges of these ebbs will need to be inserted there later).

On that part of the opening where the ebb will rest on the wall, a special profile is installed, to which the ebb will then be attached. If the height difference is small, you don’t have to install the profile, but simply apply a layer of polyurethane foam. Then the ebb should be placed under the ledge of the frame and attached to it with self-tapping screws. The ebb tide also needs to be filled along the lower boundary polyurethane foam.

Now let's take a closer look at the second method of installing plastic windows with your own hands - using plates.

This method is much simpler, although, as we have already said, it is less reliable. Installation using this method involves installing thick metal plates.

They should be installed at the same distance as the anchors in the first installation method - approximately 2 cm from the edge, and no more than 7 cm between those in the middle. The metal plates are simply screwed to the profile using self-tapping screws.

In all other respects, do-it-yourself installation of plastic windows is completely identical to the first installation method. In the same way, the window is leveled in three planes, after which all actions are identical. Simply, unlike the first method, they attach not the frame itself, but metal plates, and attach them to the so-called dowel-nails. The peculiarity of the fastening is that they first drill a hole, then bend the metal plate, insert a dowel into the hole, put the plate in place and tighten the dowel.

The main mistakes when installing plastic windows with your own hands

If you install plastic windows incorrectly, this can lead to the fact that the house will be cold; water will flow into the room through improperly installed ebbs. And the expensive structures themselves will quickly become unusable. And if professional installers sometimes make mistakes when installing PVC windows, then, of course, an amateur who installs plastic windows with his own hands is not immune from them.

Let's look at the 10 most common mistakes made when installing plastic windows.

The window size is incorrect

This is usually a consequence of incorrect, careless measurement of the window opening, and, accordingly, the manufacture of an unsuitable window structure. And in case the window is too large in size. And if the size is very small, it is simply impossible to install such structures.

Poor preparation of the window opening

If the surfaces are poorly cleaned, there is construction debris, dust, potholes left on them, or, on the contrary, parts of the wall protrude on the surface of the opening, the polyurethane foam will not fit as tightly and evenly as necessary for quality installation DIY plastic windows. In addition, this kind of pollution absorbs moisture very well, and it will soon end up inside your apartment.

Ignoring wall insulation

If a plastic window is installed without taking into account the thermal insulation of the wall, then cold air will penetrate into the apartment at the joints. Therefore, it is imperative to take into account the layers of walls when installing plastic windows. If the wall consists of one layer, the window should be placed exactly in the middle of the wall. If the wall is double-layered, the window should be installed at the very edge, as close to the insulation as possible. And if the wall is three-layer, then it is necessary to install a PVC window directly in the plane of the wall insulation, in order to avoid heat loss.

Incorrect distance between the window frame and the slope

If the window frame is located too close to the slope, the seal in this place will be of poor quality, and moisture will begin to appear and accumulate in these places. If, on the contrary, the frame is located too far from the slope, then there is a risk of deformation, since the load on the anchors or metal plates is too great.

Incorrect size of window sill

The window sill should be slightly narrower than the window frame itself. If it is a different size, or they decide not to install it at all, then water will penetrate under the window frame due to the lack of a normal seal in this place, and as a result, the wall will constantly be wet. Metal parts can simply corrode after a certain time.

Poor quality fastening of PVC window to the wall

If you skimp on dowels or anchors and there are too few of them to attach the window structure to the wall properly, over time the position of the window will change, the frame will become deformed, and it will be difficult for you to tear off and close the window.

Not enough polyurethane foam

Polyurethane foam is practically the only material for insulating a window structure and the wall itself to which it is attached. If there is not enough foam, the heat will escape. Therefore, the gap between the slope and the window frame must be filled properly, not sparing the mounting foam.

No insulation tape

If you decide not to use the insulating tape required by GOST on the internal and outside window design, be prepared for the fact that the thermal insulation will gradually become worse and worse. Accordingly, the windows will deteriorate much faster than you would like.

Therefore, if you decide to install a plastic window with your own hands, try to go through everything necessary steps and carry out all the necessary actions efficiently, carefully and without haste. Then your beautiful plastic windows, installed by yourself, will delight you and your household for many years.

Do-it-yourself installation of PVC windows is simple process, which does not require special skills or technological skills. Immediately after delivery of new windows home, you can begin self-installation, spending a little time. But it is necessary not only to carry out installation - you also need to prepare the workspace, stock up on tools and avoid possible errors which lead to negative consequences.

So, you already have ready-made PVC windows at home that you can install. First of all, it is necessary to dismantle the old window frames and prepare the workspace for the subsequent installation of new double-glazed windows.

Dismantling is very easy and requires only a few tools. These are a crowbar, a screwdriver, a hammer and a chisel. Dismantling is carried out as follows:

The first stage - we dismantle the old windows

1. First of all windows are removed. To do this, you need to use a hammer and a chisel (or screwdriver). First, the movable windows with frames are removed. To do this, use a screwdriver to carefully pry bottom loop, on which the window is attached, after which it is pryed off top loop. Afterwards, several intense but careful blows are applied from below the frame - this way it should come out of the hinges. If the movable window was not fixed tightly enough, then a small force is enough to remove it from its hinges.
2. After dismantling the movable windows, it is necessary remove the window sill. To do this, take a chisel and a hammer, with the help of which the plaster is beaten into the grooves of the window sill. We put the tools aside and take the crowbar. With its help, the window sill is lifted from below (in the area between the window sill itself and the concrete slab) and loosened - for easy dismantling it is necessary that the window sill “walk” freely. If there is any filler or fixing elements under the window sill (as a rule, in old structures there are wooden blocks for support), they are deleted. After this, the window sill is carefully lifted from the side of the frame with a crowbar and pulled forward with several sharp movements. As a rule, old window sills are loosely fixed, so removing them will not be a problem.
3. The entire window frame is dismantled. Along the perimeter of the window, the plaster is beaten off with a hammer - it thin layer hides the spacers on which the frame rests. Initially, the wooden spacers from the side are removed. After this, a part of the window frame is pulled out using a crowbar.

As a rule, many builders neglect all the rules of dismantling - wooden window sill it is simply cut into pieces with a grinder, and the concrete is broken using a hammer drill. The frames are also cut into pieces, after which they are removed from the opening in separate pieces.

Preparing the window opening and windows

After dismantling the old window frames, there will be a lot of construction waste. On the surface of the opening there may be remnants of old insulation, plaster and small debris (chips, sawdust, etc.). All this must be removed from the surface of the opening. Ideally, before installing new PVC windows, the window opening should be presented or neatly brickwork(if the house is brick), or a flat and smooth concrete slab (if the house is panel). All irregularities, cracks and chips are covered with plaster and leveled.

Is the window opening ready? Then you need to check the condition of the PVC windows. It is necessary to inspect the block for deformation, and then check that all parts are complete. Be sure to check the availability of the following components:

• Windowsill;
• Plugs;
• Mounting profile;
• Anchor plates required for fastening the window;
• Installation instructions (some manufacturers provide it in one set with the double-glazed window);
• Accessories (handles, handle caps);
• Low tide.

After everything has been checked, it is necessary to prepare tools for installation work.

Tools for installing PVC windows

To install PVC windows with your own hands, you will need the following tools:

• Building level;
• Screwdriver;
• Polyurethane foam and a gun for it;
• Hammer;
• Primer;
• Hexagons (it is advisable to have 5-6 pieces in a set);
• Pencil or marker;
• Roulette;
• Paint brush.

As a rule, installers are limited to a smaller set of tools. But since you need to do correct installation DIY plastic windows, and these windows must be installed securely, it is recommended to use the list above.

Taking measurements of windows

You can carry out two measurement methods - with a quarter and without a quarter. Let's take a closer look at each of these methods.

Taking measurements without a quarter

The PVC window is installed in the cleaned and pre-prepared window opening. To order a window, you need to make the following calculations:

• Window height: five centimeters are subtracted from the vertical of the window opening;
• Window width: three centimeters are subtracted horizontally from the window opening.

The resulting gaps will subsequently be filled with foam. As a result, the following parameters are obtained: an indentation of 1.5 centimeters is made on the sides of the opening and 2.5 centimeters on the top and bottom sides.

After this, the window sill and drain are measured. Each value obtained must be increased by at least 6-7 centimeters.

Taking measurements with a quarter

Measurements are carried out as follows: the window opening is measured horizontally at the narrowest point. The resulting value must be increased by three centimeters - this way the required window width is determined. In the vertical direction, the length is measured from the base of the window opening to the upper quarter - this way the height of the window is determined.

Based on the results of measurements, you should get the following indicators:

• Window width and height;
• Window sill width and height;
• Width and height of drain.

Installation of PVC windows according to GOST

In most cases, GOST for the installation of plastic windows is exclusively advisory nature. However, we recommend adhering to the basic requirements - this is necessary, first of all, for the home owner himself.

There are two installation technologies. Do-it-yourself installation of double-glazed windows can be done with and without unpacking windows. In the first case, it is necessary to completely disassemble the window - remove the glazing beads, pull out the double-glazed window, then fix the frame with anchor bolts in the opening, and then install the double-glazed windows and glazing beads. In the second case, the window is not disassembled, but is fixed using special fasteners, anchor plates, without the use of through fastening with dowels. The first method is considered more difficult and requires certain work skills. That is why we will consider only the second case, as the most preferable for the majority of ordinary people.

Installing windows

Before you start installing windows according to GOST, you need to create own plan. This can be either a self-developed drawing or instructions that come with the manufacturer. Following the plan will help you complete the work without errors and with maximum accuracy.

The work is performed as follows:

• The surface of a pre-prepared window opening treated with a primer in order to ensure better adhesion with hydro- and vapor barrier tapes. You need to apply the primer with a regular paint brush.
• We remove the packaging from the windows and glue it on the semi-perimeter of the frame sealing tape PSUL. This will provide additional protection for the polyurethane foam from harmful effects UV rays and precipitation.
• The window frame is installed in the opening. We will consider this point in more detail later.
• Fill the seam with polyurethane foam.
• The next step is to cover the frame internal vapor barrier. For this purpose inside The frame is glued with vapor-proof tape.

We use the following rules when installing a plastic window:

1. We put marks on those places of the frame where the fastening will subsequently take place.
2. Fastening elements are attached to the frames from the sides, while a step of 50 cm is maintained. It must be taken into account that the maximum indentation from the edges should be no more than 15 cm.
3. Fastening elements - anchor plates - are attached to the window opening with self-tapping screws.
4. The window is placed on plastic mounting wedges according to the construction level. Any deviations must be avoided.
5. For additional fixation on the sides, mounting wedges or ordinary wooden blocks are used - they are inserted into the spaces between the fasteners.

• On the outside of the window, after installing the frame, a diffuse tape under the ebb is fixed.
• The openings that remain between the window frame and the walls must be filled with foam.

Tip: When fastening the window frame using fasteners, there is no need to tightly tighten all the screws. Only after the structure is finally secured can the fastening elements be brought to the stop.

The window sill comes in one set with metal-plastic windows. The master himself determines what width it should have. Measurements are taken, after which the window sill is carefully trimmed to the required length. Next, the window sill is installed as follows:

• The window sill is installed on wooden blocks and adjusted in height. The adjustment must be carried out with a building level so that the window sill is strictly horizontal in relation to the window opening.
• After the position is finally established, the window sill is removed and plugs are put on its side parts. An adhesive mixture is laid on the wooden blocks that serve as the base for the window sill (it is recommended to use SM-11 or a similar material).
• The window sill is reinstalled on the bars and pressed a little. During this procedure, it is necessary to use a building level, since the window sill may move slightly to the side during installation.
• After the adhesive solution is fixed, the space between the window sill and the window opening is blown with foam.

Low tide installation

Either a home-made drip sill or the one that comes with a metal-plastic bag can be installed. If you purchase a drain, you need to take into account that it is attached with self-tapping screws to the bottom profile, and the part of the window protruding above it must protect the junction of the profile with the drain. The drain itself is installed extremely simply: a profile is attached to the window opening, after which the drain is secured to it using self-tapping screws. For additional protection The fastening points are blown out with polyurethane foam.

Sealing PVC windows

Technological features foaming instructions are written on the container with polyurethane foam. Each master can verify this for himself by reading detailed instructions indicated on the cylinder. The foam polymerization process is catalyzed by high humidity. That is why, before starting the sealing process, it is necessary to wet the areas with plain water. In the absence of moisture, polymerization will not be of sufficient quality.

After the foam has hardened, it must be carefully cut off using a regular stationery knife. Do this carefully so as not to damage the metal-plastic windows.

Advice: Do not try to fill the entire cavity of the assembly seam the first time. First you need to use mounting gun Apply a little foam, wait until it swells, and then reapply the required amount.

Common installation mistakes

Both beginners and experts can make mistakes when installing plastic windows. Generally, the most common are the following:

• Taking incorrect measurements or lack thereof;
• Selecting unsuitable profiles for installation;
• Installation on an uneven surface, or on a surface that has not been previously cleaned;
• Installation of PVC windows without level;
• Incorrectly secured window. Some people either use too many fasteners or none at all. There is only one result - the window may become deformed during operation;
• Installing a window at insufficient depth. If the window is placed too close to the inner edge of the window opening, the temperature around the window may significantly drop, and, as a result, condensation may form;
• Improper sealing. Assembly seams or they are not blown out with enough foam, or unevenly. This leads to the fact that after several years of operation the window begins to fog up and loses some of its advantages.

In order to avoid common mistakes, it is necessary to carry out installation exclusively according to the instructions and in compliance with technological features.

Conclusion

As a conclusion, I would like to note: installation PVC windows doing it yourself doesn’t present any difficulties. The entire process of installing one medium-sized double-glazed window lasts for one day. This takes into account not only the installation process itself, but also the time spent on dismantling, cleaning and preparation. As a result, you will not only get reliable design, but you will also significantly save your own money.

We hope that our description technological process installation of PVC windows will help you in further construction work.
