The procedure for adjusting the sashes of metal-plastic windows. Adjusting plastic windows with your own hands: choosing a tool, basic rules. Video: installing and replacing the handle

There are many materials from which windows are made. One of the most popular is plastic. Plastic windows are durable and highly resistant to moisture, frost, and temperature changes. However, in order to ensure the normal functioning of such a window, it must be adjusted. We’ll look at the features of setting the pressure on a plastic window below.

Plastic windows: advantages of operation

Installing a plastic window is a fairly simple process, the quality of which depends on the correct implementation of the technology. In addition, the quality of the window is affected by factors such as the manufacturer, the materials from which it is made, fittings, profiles, etc.

Among the advantages of plastic windows it should be noted:

  • high level of protection of living quarters from extraneous sounds;
  • high level of heat retention in the room, installation of one double-glazed window helps save more than twenty percent of heat;
  • good tightness eliminates drafts, so windows do not need additional papering before winter;
  • the service life exceeds ten years, and if you follow certain rules for using these windows, they will last two or even three times longer;
  • a high level of fire safety prevents windows from burning or igniting;
  • aesthetic appeal - windows come in almost any color or shade, in addition, to clean them, just wipe them with a damp cloth;
  • plastic windows do not require special care, they do not need to be painted periodically, unlike wooden ones;
  • The versatility of the window is ensured by such functions as the ability to ventilate it and mosquito nets that protect the room from insects.

However, windows made of plastic have certain disadvantages, namely:

  • unlike wooden windows, they are not able to maintain an optimal temperature and humidity atmosphere in the room, thereby regulating it;
  • periodically moving parts of a plastic window need to be lubricated, channels cleaned and the seal replaced;
  • in the warm season the windows increase in size, and in the cold season they decrease;
  • Technologically incorrect installation of a plastic window significantly reduces its service life.

Construction and design of plastic windows

Before studying the features of adjusting the window pressure, you should familiarize yourself with the structural elements of a plastic window, including:

  • frame;
  • doors;
  • double glazed windows;
  • fittings;
  • elements for compaction and sealing;
  • glazing beads;
  • shtulpa;
  • impost.

The frame consists of a profile on a plastic base, inside of which there is a steel reinforcing reinforcement. The profile is connected to each other using special welding. Its strength is very high and lends itself to special tests. In order to connect the steel profile with the plastic one, self-tapping screws are used. The frame must provide the window with strength and take on various types of loads.

There is also a steel profile inside the sashes. The main function of the sash is to ensure the normal closing and opening of the window during its operation. Fittings are various types of elements made of steel, such as handles and awnings. The fittings ensure ventilation of the window, its opening or closing. When choosing plastic windows, special attention should be paid to the fittings, since the quality of the fittings also determines the service life of the plastic windows.

A glass unit is an element that is capable of transmitting light into a room. There are windows with one, two, three or more double-glazed windows. Two glasses in a double glazing unit can form one air chamber. In order for the window to have good heat and sound insulation characteristics, instead of air, a special gaseous substance is pumped inside the chamber. Glazing beads are most often made of plastic; they hold the glass on the window.

In order to give the window additional tightness, an element in the form of a seal is used. With its help, moisture and cold air do not enter the room. If the windows consist of two or more structural elements, then an element in the form of an impost is installed between them. This part is made of galvanized steel reinforcing profile or plastic. The plastic version of the impost ensures complete release of the window opening. The steel elements are stationary and are fixed directly in the opening, dividing it into several parts.

Adjusting the pressure of a plastic window and the features of its implementation

Window adjustment is required if the following problems arise during their operation:

1. Drafts. If you are concerned about the windows blowing, especially in strong winds, then you need to adjust the pressure of the plastic window.

2. The frame touches the bottom of the sash. In this case, sagging of the sashes is important. In order to get rid of this problem, install vertical or horizontal sash regulators.

3. In order to eliminate the problem of the handle becoming loose, it is enough to change the location of the plate that is located inside it.

4. If difficulties arise with turning the handle, then it is necessary to change the location of the sash or lubricate the fittings in the window.

There are many options for plastic windows, which differ in quality, number of double-glazed windows, strength, etc. Each manufacturer has individual window settings.

The work of adjusting plastic windows is carried out by professionals, however, subject to certain rules, it is possible to do it yourself. In order to adjust a plastic window, you will definitely need a four-millimeter hex key and instructions from the window manufacturer. If the nature of the damage is associated with poor-quality installation of the window or its long-term operation, then they can be completely eliminated with the help of additional adjustments or replacement of fittings.

There are several modes for adjusting plastic windows; the choice of one or another option depends on the nature of the malfunction. By adjusting the window horizontally, it is possible to get rid of a slight bevel or shift of the frame. For these purposes, it is necessary to gain access to the upper and lower hinges. They have holes for installing a hexagon. The window is adjustable in two positions, both horizontal and vertical. If the hexagon rotates clockwise, then the window is attracted to the sash, otherwise, it turns out to loosen the fastening between the window and the sash and lower its lower part.

Window adjustment on the top hinge is performed only when the window is fully open. Please note that in this case, it is impossible to move the window by more than two millimeters.

In order to adjust the window in a vertical position, you must use the lower hinge. To do this, a special cap is opened on the hinges, which allows access to the hexagon hole.

If you rotate the hexagon clockwise, the sash will rise, otherwise, it will be possible to lower the sash. The window can also be adjusted by no more than two millimeters.

Technology for adjusting the pressure of plastic windows

Most often, most problems with plastic windows are eliminated by adjusting their pressure. By performing these actions, it is possible to get rid of drafts in the room and heat losses in the winter season.

To check the need to adjust the sash pressure, you need to hold a match to the window; if the flame is uneven or goes out completely, then there is a need to adjust the sash.

In order to adjust the plastic window, eccentrics are used, which are located on the fittings. They are located behind the handle clamping parts. Their adjustment is quite quick and simple.

To press the sash tightly against the surface of the frame, turn this element clockwise. Turning the eccentric counterclockwise will loosen the sash.

In addition, on the surface of the eccentric in most plastic windows there is a special indicator that helps determine the quality of pressing the sash to the frame. If the pointer is closer to the seal, then the clamp should be pressed.

Depending on the quality and type of fittings on the window, pliers or special plates installed on the sashes are used to adjust the windows. Adjusting the window allows you to move it no more than one millimeter.

In addition, the sash pressure is adjusted seasonally. That is, in the summer, when fresh air is required in the room, the pressure is weakened, and in the winter, to prevent heat loss, the pressure is increased. The operation of a window with a free clamp is more durable than with a strong seal.

When the window is in the open position, you can see the end on it. This part is distinguished by the presence of three eccentrics or trunnions. Using a hexagon, periodic adjustment of the windows is carried out.

More detailed instructions for adjusting certain windows can be found in the manufacturer's operating instructions. However, for most plastic windows, the principle of their adjustment remains unchanged.

In order to increase the clamping density, you should turn the hexagon to the left two to three millimeters. This process is quite simple, but coordination must be observed when performing it. That is, if you tighten the screw too much, the seal may be damaged. All eccentrics must be set in the same position; only in this case will it be possible to achieve uniform pressure on the entire window.

Please note that if adjusting the clamping pressure is being done for the first time, the adjustment should be minimal. After a long service life of the window, this value should be increased. Since in the process of constantly opening and closing the window, the rubber bands wear out and dry out.

If this is not done and the rubber is pressed too hard, it will wear out in a couple of months and will have to be replaced. In order to replace the old seal, it is enough to buy a new seal and install it, while adjusting the pressure. Under no circumstances should the seal be overstretched, as over time it will begin to leak air into the room.

If you have problems with malfunctioning handles on plastic windows, then just turn it at a right angle. Next, you should unscrew the fasteners that secure it to the window, turn the plates in the opposite direction and check the serviceability of the handle. If the problem cannot be solved, then just unscrew the old handle and install a new one. It is advisable to choose fittings from the same manufacturer from whom you purchased the windows.

If the seal does not perform its functions after adjusting the window pressure, then there is a need to replace it. In this case, you should loosen the seal to the maximum value, remove it from the sashes and install a new one. Replacing the seal is important once every eight to ten years. This window element has excellent performance characteristics and is quite resistant to wear. Provided that the window clamp is not pinched and the window is operated under standard conditions. If a squeak occurs in the seal during window operation, it is enough to lubricate it with machine oil.

If, after correcting the malfunctions on the plastic window, it was not possible to solve the problem, we recommend that you contact specialists who can quickly and efficiently repair plastic windows. It is much easier to eliminate problems at the initial stage of their formation than to replace damaged parts or sashes.

An important factor in the long-term operation of a plastic window is its operating conditions. The window fittings must be well adjusted. Do not wash the window with abrasive cleaning solutions or substances. In order to get rid of dirt on the window, it is enough to use a regular soap solution or water.

Plastic windows have long since come into common use and are not going to give up their positions, primarily because of their reliability and practicality. Despite this, their functionality may become impaired over time.

Don’t get upset and look for a specialist to troubleshoot problems with metal-plastic structures. Adjusting plastic windows yourself is quite possible.

It is only necessary to study some of the features of the defects that have arisen and the technologies for repairing PVC windows. Let's try to use this article to help you understand the question of how to adjust a plastic structure. Here you will find detailed instructions on how to adjust and repair plastic window mechanisms.

Types of violations of PVC structures

How to adjust plastic windows yourself, and what problems can be fixed without involving specialists? Such violations of the functionality of a plastic window include:

  • the window sash catches the frame;
  • the sash does not close completely tightly;
  • the locking bars are worn out;
  • the structure does not close because the handle is locked open;
  • the handle does not turn when the sash is closed;
  • the handle is out of order;
  • The handle doesn't turn well.

To adjust plastic windows you will need some tools:

  • pliers;
  • hex wrench size 4 mm;
  • screwdrivers of different types.

Basic requirements for window adjustment

Hex key for adjustment

The plastic window can be adjusted in several directions. Using this feature, you can adjust the operation of the structure along the frame, as well as control the degree of its pressure.

The technology for adjusting plastic windows is basically the same, apart from minor differences in the design of fittings from different manufacturers. Now we will present more detailed instructions for adjusting plastic windows for certain operating defects.

The sash catches the frame from below

If the sash catches the frame from below, then the structure is sagging

After some time of operation of PVC windows and doors, the sash of the frame is observed to catch. This fact indicates that the structure had time to sag.

In case of such violations, adjustment of the top hinge of the plastic window is necessary. When eliminating defects in the operation of the window sash, it is necessary to move it towards the top hinge and from bottom to top, thus eliminating the sagging. The adjustment scheme is as follows:

  1. First, let's open the door.
  2. We adjust the adjusting screw, which is located next to the top hinge at the end of the sash. This process is carried out using a hex key, which is turned clockwise.
  3. Remove the cap on the bottom hinge and use the key to turn it a couple of times clockwise.
  4. We check the degree of adjustment of the valves, and if the defect cannot be completely eliminated, we carry out these actions until the desired result is obtained.

The fold catches the frame from the side

Adjust the screws with a hex wrench

Opening a PVC window when the sash touches the frame leads to problems. The window device will not be able to open and tilt freely. Do-it-yourself window adjustment in the case where the sash catches the frame on the side is carried out according to the following algorithm:

  • When the sash hooks the frame only from below, it is necessary to move it towards the hinge in its lower part. This is achieved using the adjustment screw, which is located under the lower hinge;
  • When the sash catches the frame around the entire perimeter, it is necessary to adjust the screw, which is located at the end of the sash next to the top hinge.

Setting the locking frame

From time to time it is necessary to check the operation of the locking plate. Their number is usually as follows: one plank on all sides around the entire perimeter.

Self-adjustment of plastic windows is necessary if you notice wear on any of the locking strips. This may mean that the device has sagged. How to correct this deficiency? You can do this using the following actions:

  1. Open the structure slightly and remove the special plugs from the hinges, and using a wrench we begin to loosen the bolts.
  2. We move on to adjusting the top part by adjusting the screw so as to adjust the frame horizontally and then vertically. The vertical position of the window is adjusted using the lower hinge screw.

In order to check whether the setup process is happening correctly, you need to constantly open and close the structure. If the sash can open and close freely, then the process is complete.

Setting the sash tightness

The trunnion regulates the force of pressing the sash against the frame

On the side at the end of the sash, where the handle is located, there is a system of eccentrics or, in other words, trunnions. They are used to adjust the pressure of the plastic window. The clamping of the structure ensures the absence of drafts.

Each manufacturer has a different appearance of the eccentrics, but the operating principle is similar. Adjustment of the trunnions on plastic windows is carried out using pliers. To do this, turn them several turns.

The degree of pressure on the sashes differs in summer and winter. In the warm season, the pressure should be weaker than in the cold season. In winter, to prevent wind, the sash should fit tightly.

Pressure adjustment can also be done from the hinge side by rotating a special screw in the lower hinge. Particular attention should be paid to the swing-out flap. Setting up the folding mechanism is a more labor-intensive process.

In this case, you need to adjust the clamp using the screw in the top hinge. The mechanism is located near the hinge at the top. To use it, you need to open the sash slightly, then, pressing the lock, place the handle in the ventilation mode.

You can correctly adjust the screw as follows: when increasing the degree of pressure, rotate the screw clockwise, when loosening, vice versa - counterclockwise. During the setup process, do not forget to check the operation of the swing-out flap.

Adjusting the fittings

Let's start adjusting the PVC window fittings. Screwdrivers and a hex wrench are mainly used for these purposes. The handles are mainly adjusted using screwdrivers, and the strike plates are adjusted using a hex wrench. If the sash does not press well, then the bar is shifted to the side of the street.

The degree of pressure is also adjusted from the side of the hinges, where the mechanism, adjustable using a hex key, is located. The degree of pressure is set using the tongue. The more it extends, the better the sash will press. Let's consider other cases when adjustment of window fittings is needed. To learn how to adjust the sash pressure, watch this video:

Setting the handle that is blocked when the sash is open

Euro-window fittings work in such a way that when the structure is opened, the handle does not turn to the “closed” position. For this purpose, special locks are provided in the fitting mechanism.

Hide

Modern plastic windows are made using simple and reliable metal fittings, which for many years perform their functions without problems even in the factory state. However, for greater comfort, sometimes it is necessary to adjust the plastic windows yourself - for example, to better retain heat in the room in winter.

Another possible need is repair of the moving parts of the window during active use. The handle becomes loose, jams and requires replacement, the doors stop opening smoothly and effortlessly; in addition, from time to time they shift and begin to touch the frame. How to repair or adjust a plastic window without calling a specialist?

Necessary tool

It is not at all necessary to spend money on turning to professionals to fix it - repair and adjustment of these structures do not even require special tools. Here's what you need to prepare:

  • hexagon with a diameter of 4 mm - also used for adjusting bicycles;
  • screwdriver with attachments - T, TX (star, for some window models), Phillips;
  • pliers;
  • WD-40 or machine oil.

Main adjustment points

Adjustment is made at four main points:

  1. Bottom hinge - for adjusting the position of the sash vertically and horizontally.
  2. “Scissors” at the top hinge - to adjust the tilt angle of the sash.
  3. Eccentrics along the entire perimeter of the sash - to adjust the pressing force against the frame.
  4. Pen.

Adjusting the pressure of the sash to the frame

Working with windows has a number of tasks, but most often it requires adjustment for the winter, which consists of adjusting the force of pressing the window sash to the frame. This adjustment is made by changing the position of the trunnions, or eccentrics, which come in two types depending on the window model:

  • oval - adjusted by hand or pliers;
  • round - adjustable using a hexagon.

These parts are built into grooves into which, when the handle is turned, the strikers enter, cling to the eccentrics and press the sash against the frame. Depending on the type of fittings, do-it-yourself euro-window repair And involves adjusting either the trunnions or the counter hooks.

The eccentrics have three positions:

  • exactly in the center of the groove - standard clamp;
  • to the right of center - weak pressure;
  • to the left of center - strong pressure.

You need to use all three positions, since the double-glazed windows need to be adjusted several times a year - in winter, press harder, in summer - less.

If you leave the trunnions in one position for a long time, this will lead to deformation of the seal, and in the future the adjustment will no longer protect against blowing.

If there is air blowing from the hinge side, the awnings should be adjusted. This is done like this:

  • remove the plastic cap from the bottom hinge, under which there are several bolts - tightening it perpendicular to the frame will increase the pressing force of the sash;
  • The scissors are adjusted from above - for this, the same pin is used as on the sash.

Adjusting the sash position

Sometimes installation includes adjusting the position of the sash in the horizontal and vertical planes. The structure deviates from its standard position due to damage to the moving parts due to the window being open for a long time or due to careless handling of the mechanisms.

Setting the tilt angle of the sash during ventilation

The plastic window handle has 4 positions, two of which are tilting the upper part of the sash. Turning the handle all the way up is the maximum recline; positioning it between the horizontal and vertical positions is a micro-ventilation mode, useful in severe frosts.

In some cases, it is absent - the window reclines exactly the same distance as with full ventilation. Adjusting windows for winter involves changing this distance. To adjust the degree of pressure on the upper part of the sash, a pin on scissors is used.

This is done this way:

  • The window opens in ventilation mode.
  • If there is no access to the scissors in this position, you should open the window in two modes at once - fully open and ventilate. Sometimes a blocker prevents you from doing this - you can disable it by pressing the metal tab on the handle mechanism.
  • When the scissors open, an eccentric will be visible on them - the same as for adjusting the sash pressure. Tightening it with a hexagon will reduce the tilt angle, loosening it will increase it.

When the adjustment of the plastic window fittings with your own hands is completed, the sash returns to its original position.

Correcting the vertical position

The displacement of the sash in the vertical plane affects the convenience of opening and closing the window - the sash begins to touch the frame, and you have to forcefully lift it or press it down.

The vertical position of the sash is adjusted using a bolt on the bottom hinge. This is done like this:

  • The plastic cap is removed from the canopy.
  • On top of the metal part of the hinge there is a hex bolt that runs parallel to the frame. Loosening it moves the sash down, tensioning it lifts the structure.
  • If the window or balcony door is large and wide (from 100 cm), metal closers are used to facilitate closing. Along with adjusting the bolt in the lower hinge, this structural part must also be adjusted.

Shift of the sash in the horizontal plane

How to adjust in horizontal axis? For this, both canopies are used - a loop at the bottom and scissors at the top.

  • To adjust from below, you need to remove the plastic protection from the hinge and tighten the side bolt running parallel to the frame. It can be accessed both from the side of the slope and from the inside, from the side of the sash. Tensioning the bolt will move the sash to the right, loosening it will move it to the left.
  • To adjust the position of the sash from above, you do not need to fully straighten the scissors. You should open the window and find a recessed hex bolt on the inner end of the sash - it is located near the upper edge of the structure. Its weakening and tension in the same way affects the position of the sash.

Remember that such adjustment is carried out only in the open position of the sash, otherwise the mechanisms can be damaged.

Handle repair and adjustment

Active use of the window, constant impact on its main mechanism - the handle - leads to various types of breakdowns. In such cases, there is no need to call a specialist, since adjusting the handle on a plastic window is very simple.

Loosening

If the handle becomes loose, just tighten the two bolts hidden under the plastic decorative cover. To dismantle it, no tool is required - just pull the handle towards you and turn the part 90 degrees. The bolts are tightened with a Phillips screwdriver, then the fittings are returned to place.

Jamming

If the handle turns with force or does not move into standard positions, the cause is usually clogging of the mechanisms. In this case, you should unscrew the handle and clean all moving parts of the structure with WD-40 aerosol. After this, the window is lubricated with machine oil.

Adjusting the plastic window handle

In addition, the reason for poor window functioning is sometimes:

  • incorrect position of the plastic window sashes - do-it-yourself repair and adjustment in this case consists of changing their position using a hex key, as described above;
  • if the handle does not fit well into the “closed” position, this indicates that the sash is being pressed too hard against the frame - it is necessary to adjust the trunnions around the entire perimeter, loosening them a little.

Jamming

The handle getting stuck in one position is a consequence of the locking mechanism. It is necessary so as not to break the fittings - the metal locking tongue prevents, for example, opening a window when it is in ventilation mode. However, the blocker sometimes works at the wrong moment, preventing you from closing the window. This happens due to improper handling - too sudden a change in the position of the handle.

Adjusting the handle of the plastic window in this case depends on the manufacturer of the fittings:

  • The lock is disabled as follows: the sash opens, there is a metal plate near the handle, which you need to press on and turn the handle in any direction.
  • Maco and others. There is a steel tongue underneath the handle that sticks out at an angle when in lock mode. You need to press it, placing it in the “parallel to the frame” position, and change the position of the handle.

Replacement

If the standard handle is damaged or it needs to be replaced with a locking mechanism, you can install a new part yourself. This is done very simply:

  • The plastic protection is removed from the old handle.
  • The two cross bolts are unscrewed.
  • A new handle is installed and screwed on.

Such installation and repair of plastic window fittings does not take much time, and a new part can be found in any hardware store.

Thus, everyone can cope with the work, since you can adjust plastic windows with your own hands quickly and without the use of complex tools.

Fittings for plastic windows allow you to adjust how tightly they close and, if necessary, adjust them depending on the season. However, sometimes even high-quality expensive fittings require repair. In this article we will tell you how to adjust plastic windows and how you can fix minor mechanical failures yourself. To do this, it is enough to know the position and operation of the main adjustment units and have the necessary tools.

Depending on the current problem and the hardware manufacturer, for repair you will need:

  • 4 mm hexagon (almost every cyclist has it in their kit);
  • a screwdriver with bits marked T, TX (star-shaped), as well as a regular Phillips number 3-4;
  • pliers;
  • WD-40 aerosol.

Adjustment points

Let's consider popular situations when adjustment of PVC windows and fittings for winter and summer is required, and we will also tell you how to eliminate minor faults. Only the general technology will be described; some nuances may vary depending on the manufacturer. In any case, this can be found in the instructions.

Repair of window and balcony handles

Door handle loosening

To fix a loose door handle, you need to tighten its fastening. This is the simplest adjustment of a plastic window; for access to the adjustment mechanism, a pad is provided on the bottom of each handle. They pull it towards themselves and turn the entire element perpendicularly. So you can see two bolts that are tightened with a regular Phillips screwdriver. If you cannot remove the decorative nozzle with your hands, be careful: it is made of soft plastic and can be easily damaged by a sharp object.

Installing or replacing a handle with a lock

If you have children, it is important to protect them from falling out of windows. It is for this purpose that special handles with a lock were invented, which will not allow the child to open the window on their own.


To remove the old handle, first remove the decorative attachment, as in the previous version. Unscrew the two bolts and pull out the handle with gentle rocking. Then insert a new one in the same position and fix it with bolts. Replacing a window handle will take literally one minute, the process is shown in the video.

The handle sticks or does not reach the desired position

This problem occurs for various reasons. Perhaps cleaning and lubricating all the fittings and handles will come in handy here. If the handle closes with great force, adjusting the sash pressure of the plastic windows will most likely help.

To lubricate the mechanism, pull out the handle, clean and vacuum it and the mounting hole. Then all that remains is to lubricate the moving parts with a liquid lubricant, for example, sewing machine oil. If there is corrosion, the surfaces are treated with WD 40 aerosol.

Information on how to adjust the fittings of plastic windows to reduce the pressure of the sashes is presented in a separate section below.

If the handle is jammed

If it happens that the handle is jammed, you must not forcefully close it, breaking it all out. Most likely, the locking mechanism did not work correctly, which prevents the window from changing its position while it is open. To solve this problem, manually remove the locking lever located at the end of the sash next to the handle. The blocker can have two designs:

  1. a plate in the form of a tongue attached to the end, which, when the window is opened, changes its position and becomes at an angle relative to the seal;
  2. a clip that fits onto the seal when opened.

Adjusting window sashes in winter and summer

Checking the frame pressure is very simple: take a sheet of paper and press it with the sash. If the sheet is easy to pull out, it means the clamp is bad and mandatory adjustment is required. If the sheet is pulled out with difficulty, or even breaks, then the setting is done correctly.

Over time, the sealing rubber becomes less voluminous than before, and a gap may form in the window. However, more often this gap appears during seasonal fluctuations, with sudden changes in temperature. To correct this problem, it is often not necessary to change the seal. Adjustment of the sashes of plastic windows is carried out by twisting specially provided mechanisms.

Setting up your plastic windows for winter and summer is especially important if your region experiences large temperature fluctuations. This allows you to reduce the internal stress of the structure and fittings and increase the service life of the rubber seal.

    • At the end of the sash, in the slots of the metal plugs, there are oval cylinders called the trunnion (eccentric). There are grooves on the frame into which the hooks fit when the handle is turned in order to press the sash tightly. Their adjustment can be done by changing the position of the eccentrics or hooks.

    • The photo shows an example of adjusting plastic windows, which is easy to do yourself without calling a specialist. As you can see, to increase the pressure you need to rotate the trunnion 90°. Depending on the manufacturer of the fittings, it can be turned either manually or with a screwdriver/pliers. Please note that the trunnions (which are located in the photo on the right) do not rotate around their axis, but along a small radius.
    • If it is not possible to adjust the eccentrics, tighten the counter hooks on the frame; this usually requires a hex wrench. You can also place a plate under the “response” if the trunnions do not reach it.
    • When the pressure on the frame at the handle weakens or increases, you can move on to adjusting the pressure on the side of the awnings. To do this, remove the plastic plug from the lower canopy.
    • Inside you can find two hex bolts and one hidden, with the help of which the position of the frame sashes is adjusted. The clamping force is adjusted by a bolt located perpendicular to the window. It is better to carry out the adjustment with the window closed. Turning it clockwise will increase the pressure on the sash, and turning it counterclockwise will weaken it.
    • The upper part of the sash is attached differently, on a special mechanism called “scissors”. To gain access to the upper part, the window is opened and the locking mechanism is pressed at the end of the sash (it is fixed at an angle to the rubber gasket and is spring-loaded).
    • When the lock is pressed, the handle is turned to ventilation mode. The sash will be removed from the top hinge and will hang only on the “scissors” on top and on the bottom canopy. This gives access to the head, the adjustment of which will change the frame pressure.

If the edge of the sash touches the frame

When a window is left open for a long time or is opened/closed abruptly, the retaining mechanisms may become loose or deformed. If there are no serious defects, then tightening the loops should help.

    • To change the position of the sash, use a hexagon to tighten the bolts on the lower canopy and on the “scissors” system on top. Remove the protective plastic cap from the bottom hinge, and in its upper part you can find a hexagon bolt. To lower the sash, it is twisted counterclockwise, and to raise it, it is twisted clockwise.
    • On massive metal-plastic windows and doors, there are sometimes additional closers that slightly raise the sash before closing. If there is such a mechanism, then it will need to be slightly adjusted.
    • If the sash touches the frame not from the top or bottom, but from the sides, another mechanism is adjusted for this. At the bottom of the canopy, find a bolt located parallel to the window. For convenient access to it there are two exits with heads for the key (from the side of the slope and the sash).

  • If the slope is too close and does not allow access to the bolt, the sash is opened and the second method is used. If you twist it clockwise, the sash will move to the right, and counterclockwise, it will move to the left.
  • The adjustment from above is done a little differently. To do this, open the sash completely and find the slightly recessed head of the adjustment bolt on the side of the mechanism. By changing its position, you can adjust the position of the flaps left and right in the upper part.

If plastic windows are broken, repairs are quite easy to do yourself without calling a specialist. The main problems with the position and pressing of the sashes, and loosening of the mechanisms are solved literally in a minute with the help of simple adjustment of the fittings.

Adjusting the pressure of plastic window sashes is a preventive procedure to prevent possible damage to double-glazed windows.

More information about plastic windows

Plastic windows are a reality of modern homes. They increasingly decorate the facades of buildings, as they have a long service life and have a number of advantages over classic wooden windows.

However, plastic structures also have their disadvantages. The main disadvantage of such structures is the fact that they require careful operation and frequent adjustments to ensure the quality of their work and the absence of drafts.

Other problems that may be characteristic of any, even the highest quality and most expensive plastic window:

  • loose pressure or sagging of the sash;
  • jamming of locking mechanisms;
  • squeaks when closing or opening;
  • lack of fixation in a given position, etc.

Fortunately, all these problems can be eliminated quickly with your own hands. and troubleshooting other problems is a simple process that anyone who has ever held a screwdriver in their hands and knows the difference between a hex and a torx wrench can handle.

Adjusting the window pressure involves using the following materials and tools:

  • screwdrivers with flat and Phillips profiles;
  • hex or star wrenches (usually marked with the numbers “5” and “2.5”);
  • pliers;
  • metal ruler or tape measure;
  • pencil;
  • building level;
  • seal made of polyvinyl chloride material;
  • construction adhesive that allows you to hold plastic parts together, or liquid plastic that hardens after some time after use.

Despite the fact that adjusting the window pressure and eliminating sash sagging are simple procedures, they should be approached thoughtfully.

Having familiarized yourself with the information regarding the design of plastic windows, you can easily find all the plugs behind which the screws and nuts are “hidden”, and find out how to remove them so as not to damage the appearance of the double-glazed window.

Adjusting the pressure of glass panes

The window sashes are attached to the double-glazed window frame using special hinges, which can become loose and deformed during improper use.

Any damage that may occur in the area of ​​the double-glazed window hinges will inevitably lead to sagging of the working sash, creaking or other problems.

Reasons that can cause problems associated with pressing plastic window sashes:

  • improper operation;
  • excessively frequent opening and closing of windows;
  • shrinkage of the house, etc.

In order to prevent a critical situation from arising and not to initiate frequent replacements of double-glazed windows in an apartment or house, you should regularly (once every two months in the summer and once every three to four months in other seasons) inspect the windows, assessing their working condition.

If minor defects in the work are identified, they must be corrected immediately, using the tips presented in this article.


How do you understand that you need to adjust the pressure of a plastic window? You should observe the functioning of the window, especially paying attention to such nuances as the smooth movement of the sash and the presence or absence of drafts.

If the window sashes spontaneously swing open when they are not closed tightly, then not only the clamping mechanism should be adjusted, but also the tension of the hinge mechanisms should be increased.

As a rule, adjusting the pressure of plastic window sashes is done using a hex or star wrench.

You can adjust the level of pressure by tightening or unscrewing the nuts holding the window hinges together.

In some cases, to carry out work of this kind, you can use pliers or special keys (when they are supplied with the windows).

It is worth noting that there is no specific scheme according to which the pressure on plastic window sashes should be “adjusted”. As a rule, such adjustment is carried out intuitively.

To increase the pressure on the plastic flaps, you should either tighten or loosen the tension of the nuts located on the hinges. This should be done step by step, without making sudden movements.

In some cases, the cause of poor clamping of plastic window sashes may not be weak or strong tension of the nuts in the hinge mechanisms, but the banal decay of the seal.

The presence of this problem can only be detected by a detailed examination of the contour of the window sash. Have you noticed damaged areas of the seal? Replace it by first purchasing a new seal from the store that has the same cross-section and shape.

Before replacing the seal, scraps of old material should be removed from the grooves holding it.

After this, the grooves should be cleaned of small debris and must be degreased by wiping with a rag soaked in alcohol or a special solution with similar properties.


To ensure that the seal does not leave the window grooves intended for its placement, it should be glued to the plastic surface.

Please note: before closing the window and checking the level of pressure on the plastic sashes, you should wait until the glue has completely dried and the seal has “shrinked”.

Elimination of other problems of plastic windows

Adjusting the operation of plastic windows can be aimed not only at eliminating problems with pressing the sashes to the frames, but also at normalizing the functioning of other mechanisms and parts of double-glazed windows.

Many of those who own plastic windows often complain about problematic opening and closing of the “working” sash, associated with an excessively “loose” or loudly creaking handle. You can adjust the operation of the locking mechanism with your own hands.

To give the window locking mechanisms their original static quality, you should carefully inspect the connection areas of the plastic frame and handles and find small plastic parts under which the adjusting fastening bolts are hidden.

To gain access to the bolts, pry up and temporarily remove the plastic panel using a knife or thin flat-head screwdriver.

Once the plastic plug has been temporarily removed, you can begin tightening the bolts.

If the handles that unlock the sashes of plastic windows turn with difficulty, and when force is applied to them they produce sharp, unpleasant squeaks, then no amount of adjusting the tension of the bolts will help in solving this problem.

The situation can be corrected and the release mechanism can return to smooth operation by lubricating its fittings with machine oil or special oil-based solutions (for example, WD-40).

If the window sashes creak when opening, then the adjustment involves the following steps: you need to lubricate the hinges that fasten them to the frames.

If you have to exert considerable effort when opening or closing the sash, then you should take a closer look at the appearance of the hinges.

This should be done especially when the sash begins to sag and deform the thresholds and seal of the window structure.

To “pull” the sash up, returning it to its normal position, you should adjust the lower, middle and upper screws responsible for the tension of the window hinges.

As a rule, they should be turned clockwise by making one or two movements with a hex or torx wrench.

This article talked about how to adjust the pressure of plastic windows and eliminate other shortcomings that may arise during the operation of double-glazed windows. It is not difficult to carry out these procedures, especially if you have some experience in the field of repairing various structures.

If you are not confident in your abilities and are afraid of harming the performance of the window structure, then do not adjust the sash pressure yourself, but contact qualified specialists who will solve all problems in a short time.
