Do-it-yourself adjustment of plastic windows. Do-it-yourself adjustment of plastic windows for the winter

Even high-quality PVC windows lose their functionality over time and require maintenance. Adjusting the pressure of plastic windows will avoid many problems. The process of adjusting the clamp is not complicated and, if desired, you can handle it yourself, the main thing is to know where and how to tighten or loosen the fastening.

The active use of metal-plastic windows has led to the need to introduce several useful functions into their design and thereby increase user comfort. The window can be opened completely, the sash can be tilted, or it can be set for micro-ventilation. Some designs also include adjustment of the door pressure density depending on the season. Using these necessary functions over time leads to loosening and warping of the sash, breakage of fittings and difficulties with opening/closing the window. When may technical intervention in a window structure be necessary:

• when closing, the sash catches the frame;
• loose fit of the sash to the frame and the appearance of a draft;
• distortion of the structure due to window subsidence;
• it is necessary to “switch” the window from winter to summer mode and vice versa.

In addition to temporary window wear, adjustment of the window sash pressure may be necessary due to poor installation. If the installation was carried out by specialists and the window is still under warranty, then it is better to call a specialist.

General principles for adjusting the pressure of plastic windows

Adjustment of sashes for plastic windows is possible in three directions: vertically, horizontally and from below. By performing simple manipulations, you can achieve the desired position of the door in the frame and achieve the optimal degree of pressing of the seals around the perimeter of the frame.

Depending on the manufacturer, the hidden elements of the fittings and its appearance may be different, but despite this, the general principle of adjustment is the same for all designs. It is important to adhere to certain rules in your work, otherwise you can only make things worse and the window will have to be replaced completely.

When setting a window to summer or winter mode, you need to rely on the type of pressing eccentrics (special elements responsible for the tightness of the sash closing). Trunnions (eccentrics) are set to one of three modes: weak, medium and strong. Depending on which one is chosen, the clamping force will depend. Weak - would be appropriate in the summer to ensure air circulation. Strong - will not allow cold air from the street to penetrate into the room in winter. In order to make it clear in which direction to direct the rotating element, most trunnions have a special mark - a marker. If it looks inside the room, it means the window is set for winter, if the mark is directed towards the street - summer.

Types of pressure adjustment for PVC windows

There are two options for adjusting windows - along the horizontal and vertical axis. Which one is appropriate depends on the nature of the problem. You can adjust only the top or bottom loop and everything will work stably. But there are also cases when you have to spend several hours balancing the window sash in the correct position. To make adjustments, you need to reach the top or bottom hinge. On them you will find special holes for hexagons.

Horizontal adjustment

On the horizontal side, the sash needs adjustment if the frame is beveled in height. Because of this, the window may not close or may not function as intended. This situation can be caused by shrinkage of the structure, improper use of the window, or loosening of the fittings.

The horizontal pressure is adjusted using the upper or lower loops. The process is carried out by moving closer to the loop or further from it. By making clockwise adjustments in the top hinge with the door open, you can strengthen the pressure and raise the bottom of the window. To achieve the opposite result, i.e., to lower the bottom of the sash and loosen the pressure, you need to perform counterclockwise manipulations.

The lower hinge is adjusted indoors when the window is open, and outside when it is closed. The steps are similar to those carried out with the top loop.

The process of horizontal adjustment at the bottom will allow you to change the position of the frame by 2 mm or eliminate the bevel, which caused the door to rub against the frame when closing.

Vertical adjustment

Adjusting the sash vertically allows you to raise or lower it by a couple of millimeters. Manipulations are performed in the lower hinged loop. To begin with, the decorative cap of the hinge opens, under which the hole for the hexagon is hidden. Calibrating clockwise will raise the sash, moving in the opposite direction will lower it.

Necessary tools for adjusting the pressure of plastic window hinges

To perform adjustment work for pressing plastic windows, you must have a set of tools on hand. Depending on the accessories you will need:

• set of hexagons;
• flat and Phillips screwdriver;
• pliers;
• a set of stars.

With the help of these simple devices it is possible to solve not only the pressing of window sashes, but also to adjust distortions and problems in the fittings.

Technology for adjusting the pressure of plastic windows

Adjusting the pressure of plastic windows is carried out for various reasons and is carried out in several directions. This adjustment can correct almost all problems related to the functionality of window units. The procedure technology is the same for any PVC structure. Differences can only be in the type of fittings.

Usually a specialist is invited to carry out the work, but if you stock up on some knowledge, you can solve the problem yourself. To determine whether adjustment is needed, you can hold a burning candle or match to the closed door. If there is a draft, the flame will fluctuate and you need to tighten the pressure.

How to understand where a hidden window clamp is needed? If you open the window, you can see three eccentrics at the end of the door. They serve as elements for strengthening or weakening the pressure. How they need to be controlled is detailed in the instructions from the manufacturer of plastic window structures.

Changing the pressure in the winter-summer direction is necessary a couple of times a year, when the season changes. In summer it is desirable to have natural air circulation, in winter it is necessary to ensure complete tightness. This is achieved by changing the pressure density of the window sash. For these purposes, the door has special movable metal protrusions - trunnions, which in turn are equipped with an eccentric. By changing the position of the trunnions, you change the intensity of the pressure, that is, the thermal insulation of the window increases or decreases. Weak density corresponds to the summer season, standard and strong density corresponds to the winter season. In new PVC windows, the default pressure is most often set to medium pressure, so before switching to the winter period it is recommended to check whether there is ventilation. If it is missing, it is not recommended to touch the trunnions, otherwise you can squeeze the seal and over time it will lose its elasticity.

Trunnions come in various types. Depending on this, the tool for the job is selected. The protruding oval elements are adjusted using pliers. If the trunnions are round and have a slot in the center, then the pressure is adjusted with a hexagon.

When adjusting the window in winter-summer modes, make sure that all the pins are in the same position. It needs to be changed not only on the outer sash, but also on the inner one. The centers can be located on the inner sash, also on the bottom and top.

Getting rid of drafts

Adjusting the window pressure in order to get rid of blowing can occur due to the skew of the window structure. Such a nuisance occurs as a result of shrinkage of the house. The window sags, the contact of the locking protrusion with the counter plate is lost. Here the adjustment process is slightly different. The sash needs to be moved to the side so that those trunnions that do not reach the plates catch on them.

First, determine which of the metal protrusions do not reach the locking plates. The sash is examined and the places where there are protrusions are remembered. The window closes. Holding the door frame with your hand where the trunnions are installed, you need to pull it towards you. If there are no problems, the frame remains motionless, if there is, it will move. In this way, it is checked in which places there is no contact, and it is determined how to adjust the pressure of the plastic window: with an offset to the left or to the right. The adjustment is made on the lower and upper hinges.

When working with clamping mechanisms, the main thing is not to overdo it. Don't over-tighten the screws or you risk damaging them. The first adjustment of the window sash pressure should be minimal so as not to bend the sealing rubber. In the future, the clamping force is gradually increased, since regular cycles of opening and closing the window lead to wear of the sealing elements.

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 plastic windows for winter and summer is especially important if your region experiences large temperature changes. 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 hexagon 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.

Metal-plastic windows made of polyvinyl chloride (PVC) are considered to be a qualitatively new level of comfort in our home.

When installing such structures, you will need the help of a professional, but how to adjust plastic devices yourself during everyday use is given below in the recommendations.

Having replaced traditional old wooden windows with modern ones, you need to periodically inspect the operation of the opening and closing mechanisms, the condition and functioning of the fittings, which will increase their durability and functionality.

Tools and places for adjusting plastic window fittings

We recommend that serious breakdowns and malfunctions be adjusted by specialists from the Windows Expert company ()

The most common malfunctions that can be dealt with without the help of a specialist:

• When closing, the transom touches the frame from below or from the side.
• The fit to the transom frame is not tight enough.
• The locking bars are worn.
• When the sash is open in the “closed” mode, the window frame does not open due to the handle being blocked.
• The handle, loosened, does not fit tightly to the frame or is very difficult to turn.

You can troubleshoot using the following tool:

• pliers or pliers;
• hex key (size 4 mm);
• flat and figured (phillips) screwdrivers;
• a set of “star keys” for adjusting the clamping force;
• scissors for cutting the seal;
• oil can for lubricating fittings.

Basic rules for setting up PVC windows yourself

In modern metal-plastic windows, in order to achieve optimal compression of the seal along the entire perimeter of the sash, adjustment is carried out in three projections.

Individual elements, settings of transom fittings and tools may differ, but the instructions given below are used as a basis.

Summer and winter adjustment mode

A distinctive characteristic of modern PVC window fittings is the ability to switch them to “winter” or “summer” modes.

Window fittings are:

• budget;
• standard;
• specialized.

Due to the low price, budget-type fittings have limited functionality. It is produced mainly by domestic manufacturers and is used in new buildings. Such metal fittings do not have the function of switching between different seasons; it only allows the transom to close and open.

A plastic window, even if professionally installed, requires maintenance from time to time. A window can serve you for a couple of years without any major complaints, but over time, friction may occur when opening. Problem No. 2 is the rubber seal coming off, and the third is that the handle turns with serious effort.

All of the above breakdowns are not complicated and can be fixed quite simply without the need to call a specialist: adjusting plastic windows on your own is not difficult and not time-consuming. You just need to tighten or, on the contrary, loosen a couple of screw connections. The main thing is to know how this operation is done correctly. Actually, we’ll talk about this next.

The most popular operation is cleaning the rubber seals, lubrication and seasonal adjustment of plastic windows: in winter you need complete tightness, in turn in summer you want a greater influx of fresh air mass. This can be achieved by adjusting the fittings of the pressing plane of the plastic window sash.

This operation is quite simple. When you study it, you will be surprised in reality that everything is elementary...

Adjusting plastic window fittings

The window frame is pressed against the trunnions. These are a kind of metal protrusions on the side of the welding surface. When the handle is turned, they pass over the metal counterplates mounted on the frame. To allow tight adjustment of the fit between the frame and the sash, they have an eccentric - either they themselves are made in the shape of an oval, or there is an offset adjustment in the center of the protrusion. By changing the location of the trunnions, you can change the pressing force, in other words, eliminate the draft from the sash.

Adjusting sash clamps in plastic windows

From practice, we can conclude that the shapes of the locking protrusions can vary significantly. For routine adjustment of plastic windows, various types of tools are used. If you have oval-shaped windows, their position is changed using pliers: they should be clamped and turned to the side.

If the lug of the locking device is round, as shown in the left image, it is quite possible to make a slot in it for a hexagon. After a detailed inspection of them, you will be able to understand what tools you need: a standard screwdriver or a 4-point hex.

Adjusting plastic windows yourself

The eccentric is rotated using pliers or a hexagon

When systematically adjusting the window fittings, do not forget that a weak clamping mechanism corresponds to the warm season, while a standard or reinforced one corresponds to the winter season. If preventive work is carried out in the winter, first you need to move the window structure to the standard position and check whether there is any ventilation. At the same time, analyze the condition of the rubber bands on PVC windows. In winter, the rubber seal installed around the perimeter is pressed and, moreover, tightly. Over time, tension can cause elasticity to deteriorate. The standard type of seal has a 15-year factory warranty. But, despite this, if you set the pressure to maximum, the rubber will wear out much faster. Conclusion from the above information: the position of PVC windows for the winter-summer periods is set by adjusting the position of the locking pins.

Adjusting the plastic window from blowing

It happens that PVC windows, after moving the trunnions to the stage of powerful pressure, become not airtight - they begin to blow out of the sashes and it is absolutely useless to change the rubber band. This can happen when households shrink. In this case, normal subsidence is observed. At this point, there is a loss of contact between the locking lugs and the plate. When you turn the window opening handle, the trunnion protrusion goes behind the plate, thereby pressing the entire sash. If all this does not happen and there are drafts, the heat is gradually blown out of the room.

Adjusting PVC windows

When PVC windows sag, the adjustment is slightly different: first we move the sash one way so that the protrusions that do not reach the plates end up catching on them.

To begin with, decide which trunnions do not reach the locking plates. This is done mechanically. First, we recommend that you inspect the sash and clearly remember where the protrusions are present. The window should be closed. Grasp the base of the sash frame where the trunnions are mounted and pull it towards you.

If there is contact, the frame will be motionless; if this does not happen, everything should be moved. So you gradually check where the contact is missing and plan in which direction the sash should be moved. This is done by adjusting the lower and upper loops.

Adjusting plastic windows: adjusting the lower hinges

If the PVC window is difficult to close in the lower area, the sash should be moved using the hinge located at the bottom. There are two adjustments here: one is carried out along the so-called horizon - it moves closer to the hinges or further away from it, and the second, respectively - in the vertical - lowers or raises the sash by a few millimeters.

To move the lower sash compartment closer or further to the hinge itself, it is opened slightly. At the bottom of the loop there is a hole for a hexagon (less often - for an asterisk).

Adjusting plastic windows

Adjusting the bottom hinge in a PVC window or door

A hexagon is installed in the window, after which, by turning clockwise, the lower corner moves closer to the hinge, and counterclockwise, it moves away. Having moved the sash, you need to try to close/open it. Immediately after achieving the desired result, you should stop. If the resource is twisted all the way, and there is no result at all, return everything to the standard position: this adjustment is not correct.

With this screw you can slightly correct the current state of affairs if, when closing the window sashes, the frame at the bottom touches. By bringing it a little closer to the loop, you will eliminate this malfunction completely.

On the hinge located below there is a second screw necessary for adjustment. To make it easier to get to it, you should set the sash in the ventilation position, and then remove the trim. It can be removed by simple steps; you need to pull the edge in your direction by about 1-2 mm and pull it up. After removing the cap, you can see a recess at the top. 4 mm is installed in it. Hexagon. By turning it clockwise, the sash goes up, while turning it counterclockwise, it goes down.

Adjusting the top location hinge

If you can’t cover the top corner of plastic windows, you should move it a little. To do this, you should open the window at least 90 degrees. Of course, you can do less, but it will all be very inconvenient to function. There is a loop on the top flap. Purely structurally, it differs in that it is located at the bottom; it also has a hexagon adjustment.

Adjusting the plastic window - top hinge

Adjusting the top hinge of the PVC window

The adjusting screw is located on the side of the structure. Making a rotational movement, we move the sash away from the hinge (if the distant trunnions from the location do not close) or are located closer to the hinges. One aspect is that there should be a gap of a couple of millimeters between the hinge and the sash: it is needed so that the tilt and turn mechanism can fit in there. Based on this, turn the key by 0.5 amplitude and check how the window functions.

Hello dear readers!

We carried out a general cleaning of the house.

While my wife was washing the windows, it turned out that the handles were a little loose. It's easy to tighten them if you know how to do it. I have already taught my wife.

Now I gathered my thoughts and decided to write a useful post for you.

I tried to collect all the tips into detailed instructions, in which you will find not only information about setting up the handles, but also a lot of other things.

All you have to do is try them out.

The active use of metal-plastic windows in today's realities is caused by a number of advantages of these structural elements.

And if such indicators of windows as reliability, durability and aesthetics are initially included in their design, then in order to obtain high-quality consumer criteria (warmth, sound insulation), it is advisable to carry out timely maintenance of the systems.

Moreover, in order for the adjustment of plastic windows with your own hands to be carried out at the highest level, it will only be enough to stock up on a minimum set of tools (a set of star keys, pliers, a set of hexagons, screwdrivers) and accessories.

The list of main faults that can be corrected by the consumer independently includes the following items:

• Rubbing of the window sash against the frame during the process of opening and closing it;
• Loose fit of the sash to the base of the window frame;
• Broken handle.

Do-it-yourself adjustment of PVC windows

To begin with, it is advisable to consider in detail the method of window adjustment. So, if it is necessary to change the location of the sash (for free opening), then it is advisable to carry out a series of sequential procedures:

1. Open window;
2. Turn the adjusting screw located in the end part of the sash (top hinge area) 3 - 5 turns clockwise;
3. Close a window;
4. Remove the protection from the bottom hinge;
5. Using a hexagon, turn the lower hinge adjusting screw 3 to 5 turns clockwise;
6. Check the functionality of the window and the absence of chafing during operation, and, if necessary, re-adjust the element.

In a situation where it is necessary to strengthen the degree of contact of the sash to the base of the frame, proceed as follows. First, for these purposes, a system of eccentrics is used, which are located at the end of the sash on the side where the handle is located.

Helpful advice!

When it is necessary to strengthen the degree of contact of the sash to the base of the frame, an eccentric system is used

To do this, the eccentrics must be moved to the appropriate position using pliers or a hexagon.

In some window models, the eccentrics are designed in such a way that in order to adjust them, you just need to pull the eccentric towards you, then make the necessary rotation, and only after that release the eccentric (it will be pressed due to the spring).

In general, experts recommend performing a similar procedure for adjusting eccentrics twice a year (the off-season period), increasing or decreasing the degree of compression.

However, using this method it is possible to adjust the window pressure from the side where the handle is located. When the user needs to increase the pressure on the sash from the side of the awnings, they proceed in a different way.

So, if it is necessary to ensure stronger pressing of the sash (from the side of the awnings) of a swing-type window structure, then use the adjusting screw on the lower hinge.

When it is necessary to carry out a similar procedure for a tilt-and-turn structure, it will be necessary to perform additional adjustment of the window sash pressure due to the upper hinge.

To do this, you should perform the procedures in the following sequence:

1. Open the sash;
2. Turn the sash handle to the “ventilation” position (simulating closing the window by pressing the lock);
3. To increase the pressure on the sash, you should rotate the adjusting screw on the hinge clockwise, while to loosen the pressure, you need to rotate the adjuster in the opposite direction.

Certain types of window fittings are adjusted using special responds (usually located on the window frame on the handle side) which can be adjusted using hex keys.

So, to press the window sash more firmly to the base of the frame, you will need to move the sash outward (towards the street). They also use clamping mechanisms located on the frame on the awning side.

They are adjusted using a hexagon, and stronger pressure of the sash against the frame will be ensured when the tongue of the mechanism is extended more strongly.

A fairly common defect in a metal-plastic window is the tight rotation of the handle. Often this circumstance may be caused by the fact that the fittings do not have sufficient lubrication.

In this case, window repair comes down to simply lubricating the locking mechanism and all rubbing elements with machine oil or aerosol lubricant (for example, WD-40).

A similar method is used to adjust the doors of balcony blocks.

In a situation where you need to completely replace the handle, you should pull the decorative trim of the handle towards you with your fingers and then turn it 90º (to free access to the screws).

By unscrewing the mounting screws, the handle can be easily removed. And the procedure for attaching the new handle must be performed in the reverse order.

It should be noted that the key to long-term and high-quality operation of a window depends on the timely completion of service operations, and even in the absence of visual defects, it is advisable to carry out these procedures at least once a year.

For this purpose, all main components must be lubricated, and the rubber seals must be moistened. It is also necessary to say a few words about the rules for using windows:

• The window handle should only be turned when the sash is completely closed;
• Do not allow the presence of foreign objects in the free cavity of the window frame;
• The operation of windows should be carried out taking into account the completion of all finishing works (slopes).

However, it should be noted that despite the elementary nature of the described methods, troubleshooting and window adjustment should be started only after a detailed familiarization with the operating principle of the installation.

Otherwise, a more correct method would be the help of specialists in the specified field.

To correctly and safely adjust plastic windows, you need to know several features of their design in order to avoid any damage.

Next, we will tell you how to solve some problems that may arise with metal-plastic windows, and also share recommendations on how plastic windows should be adjusted correctly.

In order to independently adjust a plastic window, you need to use a 4 mm hex key, which is popularly called a “four”.

Types of adjustments

1. Let's first consider the horizontal adjustment of metal-plastic windows. To properly adjust the window, you must use the top and bottom hinges, which have a hole for a hex key.

By rotating the hex key clockwise, the sash is pulled to the hinge. The bottom of the window opposite the hinge should rise slightly.

2. If the hinge is to be moved away from the sash, the key should be rotated counterclockwise accordingly, which will cause the bottom of the sash to lower slightly.

The lower hinge is adjusted indoors when the window is open, and outside when it is closed.

The adjustment process is carried out the same way in two versions. By adjusting the frame in the horizontal plane, the frame can be moved up to 2 millimeters, and the bevel can also be eliminated.

3. Vertical adjustment of the window is carried out using the lower hinge. The hex key is placed under the cap that covers the hinge.

Elimination of the frame bevel in the vertical direction is also possible up to 2 millimeters.

4. Adjustment of the casement mode is carried out by eccentrics, which are located around the perimeter of the PVC window. When turning the handle, the eccentrics should go beyond the pressure pads, which are also located along the perimeter of the window.

By rotating the eccentric to the right, you can strengthen the pressure of the window to the frame; when rotating to the left, the pressure will loosen. There is a mark on the eccentric that indicates the degree of pressure.

If the risk is directed towards the seal, the window is pressed tightly against the frame, but if it is towards the outside, it is weakly pressed. In order to rotate the eccentrics, you can use pliers or a wrench.

Sometimes plates located on the window sash are used for clamping.

The appropriate level of window pressure to the frame depends on the time of year.

It is quite clear that in winter the pressure should be strong and in summer weakened. The pressure can be adjusted within a range of 0.8 millimeters.

5. You can adjust the loop pressure for both loops at once or for just one loop. This will depend on what hardware is installed on your window.

If necessary, adjust the lower hinge by first removing the cap and then rotating the bolt, which is located perpendicular to the window, in the desired direction.

6. The top hinge can only be adjusted on tilting sashes. When adjusting the top hinge, the frame must be supported, since it will only be supported by the bottom hinge.

Some plastic windows are equipped with a lock that prevents the open window sash from tilting. Lockers are a lever or a clip.

In order to tilt open the plastic window, you need to turn the handle to the ventilation mode while simultaneously pressing the lock.

When is PVC window adjustment necessary?

By adjusting, you can eliminate many problems with metal-plastic windows:

• The window sash is sagging, causing the sash bottom to touch the plastic frame. Adjustment of horizontal or vertical plane is suitable.
• Vertical or horizontal movement of the sash has resulted in the middle sash part touching the frame. To fix the problem, you need to move the sash evenly to one side.
• When air enters through the seal, it is necessary to adjust the sash pressure.
• To adjust a loose handle, turn the plate located at the base at a right angle and tighten all the screws with a screwdriver. The base of the handle can also be equipped with a ventilation control plate – “combs”.
• Using machine oil, you can get rid of such a problem as the handle turning tightly. To lubricate hinges, eccentrics, clamping mechanisms and platforms, you can use any brushes or cotton swabs that you have at hand.

When is adjustment required? Here are the most common signs that a window is ripe for adjustment.

• When opening (closing), the sash clings to the fittings or to the frame.
• There is a noticeable draft coming from the window.
• The handle became loose or, on the contrary, became very tight.
• When the window is open, the handle is jammed and the window does not close.

I would like to warn you right away that some problems are the result of a violation of manufacturing or installation technology. Unfortunately, not all of them can be corrected by adjustments...

We will consider adjusting balcony doors separately!

Before we begin studying the topic “Adjusting plastic window fittings,” let's define the terminology. The fittings consist of several main units, each of which is responsible for its own section.

The part on the sash is usually called the “Locking mechanism”, and the parts attached to the frame are called “Taps”.

To work we need the following:

• A set of hex keys.
• A set of nozzles - stars.
• Spatula for working with double-glazed windows.
• Putty knife.
• Rubber hammer.
• Linings for double-glazed windows of different thicknesses.
• Screwdrivers and pliers.
• Lubricant for fittings.
• Soft brush.

Much of the above may not be useful to you, but if you are going to start adjusting the fittings of plastic windows, it is advisable to prepare thoroughly.

Before moving on to practical exercises, I will make a short digression.

Note!

You should NOT adjust the fittings of plastic windows yourself in two cases.

Firstly, if the warranty period has not expired. You still don't know what you'll get, but you'll probably lose your warranty.

Secondly, if you are not confident in your capabilities. In this case, it would be more advisable to turn to professionals.

Well, with those who are used to solving their problems on their own, we move on.

Now let's decide which node is capable of what.

The lower hinge allows you to move the bottom of the sash up and down, left and right and adjust the pressure.

The trunnions of the locking mechanism are responsible for pressing the entire sash.

In some types of fittings, the clamp is adjusted by responders on the frame.

With the upper part of the tilt-and-turn mechanism, called “scissors,” you can move the top of the sash left or right and work with a clamp.

Now we will take each case and analyze it in detail. Go ahead.

Let's continue our analysis of the topic How to adjust plastic windows.

What to do if the bottom of the sash on the handle side catches on the sash or the frame - the sash is sagging. I want to say right away that large, heavy sashes MUST have a “microlift”.

This mechanism, at the moment of closing the sash, resting against a special answer, lifts the sash by 2-3mm, thereby relieving the load on the remaining parts of the fittings. For example, installing a balcony door without a lift is unacceptable!

And so, the sash sagged. This can be treated either by lifting the sash upward, or by moving the bottom of the sash towards the sagging side, and the top towards the hinges.

To raise the sash, remove the decorative cap from the bottom hinge, insert the hexagon into the hole from above and tighten the stop screw.

To move the bottom of the sash, rotate the screw on the frame part of the hinge.

The top of the sash can be moved with a screw located in the scissors from the top hinge side. To get to it, you need to open the sash and rotate the screw to the desired position of the sash.

In general, try not to keep the doors open for too long, so as not to sag.

• If the handle is loose, remove the decorative plate underneath it, turn it 90* and tighten the two screws. If, on the contrary, the handle begins to turn more and more difficult, you can hear a crunching sound in the mechanism, then it’s time to do a complete revision of the window fittings.
• How to adjust plastic windows, if the handle is turned further, to the “ventilation” position, the sash falls out and hangs on the scissors, resting on one lower hinge. This means that the blocker did not have time to work.

It is usually located on the locking mechanism in the area of ​​the handle and when the sash is open or tilted for ventilation, it is located at an angle to the locking mechanism. In this position, the blocker prevents you from turning the handle where it is not necessary.

In our case, to return the sash to its place, you need to move the plate to the sealing rubber with your finger, set the sash to the “just open” position (press the top of the sash from the hinge side) and turn the handle to the desired position.

How to adjust plastic windows if drafts appear.

First of all, carefully inspect the sealing rubber on the sash and frame.

If diaper rash, abrasions and tears are clearly visible, the tires need to be changed. If you decide that the rubber is in order, then you need to increase the pressure of the sash to the frame.

First, check the alignment of the locking rods (trunnions) on the sash with the strikers on the frame, as in “Adjusting the balcony door.”

On the lower hinge, the clamp is controlled by a screw located in the body of the part of the hinge that is on the sash. Depending on the brand of accessories, you will need a screwdriver, a hexagon or an asterisk.

But, unfortunately, not all manufacturers install bottom hinges with pressure adjustment on windows.

In this case, you will have to adjust the pressure on the hinge side using “scissors”, a “hidden clamp” and a pin on the “middle lock”.

An eccentric screw located on the scissors is responsible for the pressure in the area of ​​the upper hinge.

To make it available, do this:

1. open the door
2. press the blocker against the rubber with your finger
3. turn the handle up
4. and, carefully, move the top of the sash away from the frame so that the scissors become visible.

The blocker can be of a different design, where the blocking is performed by a movable plate, which is pressed by the sash against the frame.

This means that to unlock it you need to press the plate.

We insert the hexagon into the eccentric head and turn it in the desired direction (each brand has its own direction).

Pressing the blocker, we return the sash to its place.

Helpful advice!

On large sashes, on the hinge side, as a rule, a hidden clamp is also installed.

It is also adjustable (usually with a hexagon) according to the “winter - summer” type.

When rotating, the pressure plate extends and retracts, thereby changing the clamping force.

If an unregulated one is installed, and you are convinced that it does not work, you need to change it.

Depending on the brand of fittings, this is done either with a hexagon or pliers. On some trunnions, the eccentric is made in the form of a ring, which must be pulled away from the sash with your fingers and turned to the desired angle.

There are brands of accessories in which the clamp is controlled by the responses, I think you can decide. And in general, adjusting plastic windows is a very creative process! Especially the first time.

After all the necessary screws have been turned, we check the clamp.

This is done like this: you tear off a strip of newspaper the width of your palm and the length of two palms, and squeeze it between the sash and the frame, where there are no answers. If the strip comes out easily, add pressure.

So you check several points from all sides.

Yes, I missed one point. It happens that after lifting or tilting the sash, the trunnions begin to catch on the hinges or, on the contrary, do not reach them. In this case, the answers need to be shifted in the right direction.

We unscrew the self-tapping screw that secures the answer to the frame and, without removing the answer itself, lightly tap the answer along the frame with pliers and move it in the desired direction. We tighten the self-tapping screw.

And now - the most dangerous type of adjustment of plastic windows. This is a glass unit adjustment. There is a situation when the sash is raised all the way, and its lower part, on the side of the handle, clings to the frame.

That is, it sagged more than the travel reserve of the adjusting stop in the lower hinge. I’ll say right away that under normal conditions such a case practically never occurs, which means that one of three points was violated:

1. Correct assembly.
2. Correct installation.
3. Correct operation.

Or perhaps all three! But, as they say, “it’s too late to drink Borjomi” - we’ll treat it. Another case is when the “pivot” sash sagged. In order to save money, such sashes are often equipped with NON-ADJUSTABLE fittings.

That is, the usual loops and constipation. Here, adjustment is possible ONLY with a double-glazed window.

So let's get started: using the screw in the bottom hinge, lower the sash as far as possible.

Carefully remove the glazing beads with a spatula (the sash is closed!!!), holding the double-glazed window (it’s better to work together).

We mark the beads “left”, “right”, “top” and remove the glass unit itself. We carefully place it on something soft (a doormat, rug) against the wall, placing, for example, several newspapers away from the wall.

Then we open the sash and place spacers on the frame in the very corner on the handle side, so that the sash rises by 5-7mm when closing. We close the sash, as if pushing (lifting) it onto the gaskets.

If we notice that at the moment of closing the entire sash rises, and not just the desired edge, then in the area of ​​the scissors, on the sash, we insert another one, without letting the sash go up.

Thus, in the place where the sash was rubbed, a gap (margin) of about 5 mm was obtained.

We insert the double-glazed window and secure it tightly on all sides with gaskets, according to the technology, helping ourselves with a spatula. The gaskets must be inserted very tightly, but carefully - glass is glass.

We hammer in the glazing beads with a rubber hammer, starting with the short ones.

We check the operation of the sash by removing the linings from the frame. If necessary, we make adjustments to achieve normal operation.

All this can be avoided if you install a “microlift” on the sash.

In some types of fittings, a blocker can be used as a lift. But only those that have a fairly powerful blocker are suitable.

This is done like this: the locker's response is installed in such a way that when the sash is closed, the blocker does not just press against the rubber, but, as it were, runs over the response, lifting the sash by 2-3mm.

But you need to check it very accurately so as not to break the lock. By the way, if you install a microlift on a non-adjustable sash, opening will not be necessary.

This was an adjustment of plastic WINDOWS, but we also have doors...

We remove the old rubber.

We clean the groove from any remaining glue and sealant. Now we need to determine what kind of tires we had.

Leading profile manufacturers mainly use four types of rubber:

• Rehau
• KBE 228

We determine which one we have. If the seal is not similar to any of these types, we take any one with a similar leg size.

If you have a choice, it is better to take a German one - the service life is almost twice as long.

We insert new rubber, starting from the top of the window (door).

Try not to stretch the rubber, but rather to gather it in. Be especially careful when inserting the seal in the corners.

Then tuck the tail end-to-end with the other end of the seal, smearing the ends with glue.

The help of one more person will not be superfluous here.

Let's turn the handle to the "open" position, but do not open the sash.

Remove the decorative trim from the top hinge.

Using a flat screwdriver (knife, chisel, etc.) we pull out the pin of the upper hinge, maybe not all the way, but only to disconnect the hinge parts.

We slightly tilt the sash towards ourselves and, lifting it up, remove it from the lower hinge.

We remove the upper loop (scissors) from the groove to make it more convenient to work.

We change the seal, as on the frame.

We assemble the mechanism and put the sash in place. We drive the pin of the upper loop and put on the decor.

We close the sash and check the operation; if necessary, we adjust the settings.

Now manufacturers are offered profiles with rubber already glued in. When a window (door) is assembled from such a profile, the rubber in the corners is fused during welding.

If it is difficult to remove rubber in the middle of the profile, it is possible, but in the corners it cannot be pulled out.

Let's do this. We tear out all the rubber that lends itself, helping ourselves with a screwdriver or something else.

In the corners we mill out a groove for the rubber using a 4 mm drill bit or a vertical cutter of the same diameter.

We clean the milling area with a knife or chisel.

We insert new tires.

Detailed instructions for adjusting plastic windows

Nowadays, the popularity of plastic windows is no longer in doubt, because they are not only of high quality, but also affordable. Not to mention that they are easy to use and provide excellent noise protection.

But despite this, even the best quality windows require maintenance, so from time to time you need to call a specialist to adjust them. Many people ask the question: “Is it possible to adjust plastic windows without calling a specialist?”

It's actually not as difficult as it might seem. Therefore, after reading this article, you will be able to cope with minor problems yourself. Remember that this way you save not only money, but also time.

Now let's move on to the instructions themselves and consider the main problems.

What are the most common problems that you can fix yourself?

Most often you may encounter the following types of malfunctions, which you can easily eliminate on your own:

• When closing, the sash touches the frame from the side or bottom
• The sash does not fit tightly enough to the frame
• Wear of striker plates
• The handle is blocked when the sash is open in the “closed” mode, the window does not close
• The sash is closed, but the window does not close, the handle does not turn
• The handle is broken

Note!

After reading this article, you will be able to deal with minor problems yourself.

For repairs we may need the following tool:

• Pliers
• Hexagon (4 mm)
• Screwdrivers (phillips and flathead)
• Set of "stars"

Briefly about the general principles of adjusting window sashes

The sashes of almost all modern PVC windows can be adjusted in three planes, thanks to which you can achieve the correct position of the sashes in the frame and achieve the optimal degree of pressing of the seals along the entire perimeter of the sash.

The methods for adjusting the sash fittings, the appearance of its individual elements and the tool used for adjustment may vary depending on the manufacturer, but in general the general adjustment scheme looks as shown in the figures below.

Now let's look at what needs to be done to fix the problem in each of the above cases.

When closing, the sash touches the frame from below

In this case, you need to move the sash in the direction of the top hinge and up. The procedure is approximately as follows:

1. We open the door.
2. Using a hexagon, turn the adjusting screw located near the top hinge at the end of the sash clockwise several turns.
3. We close the sash.
4. Remove the cap from the bottom loop.
5. We insert the hexagon into it and make several turns clockwise.
6. We check the free movement of the sash and, if necessary, make adjustments until the problem is eliminated.

The sash touches the side of the frame when closing

In this case, you need to move the sash in the direction of the hinges, to do this:

If the side of the sash only touches the frame from below, then it will be enough to move the sash in the direction of the lower hinge. This is easy to do using the adjusting screw located under the bottom hinge.

If the side of the sash touches the frame along its entire height, you will also need to move the sash in the direction of the top hinge.

Wear of striker plates

To check the striker bars, open the window and inspect them. Most often there is one strip on each side along the perimeter of the window. If wear is noticeable on one of them, this may indicate that there is unevenness in the fit of the window in the frame.

In order to solve the problem, you need to open the window, remove the plastic plugs from the adjusting bolts (they are located on the lower and upper hinges, on the same side as the sash) and use a hex key (four mm) to loosen the bolts themselves.

After this, adjust the position of the top half of the window. The adjusting screw will help you with this. First, you need to adjust everything relative to the frame “left - right”, and then go to the bottom screw and adjust the movement “up and down”.

It is very easy to monitor the accuracy of the adjustment. To do this, you just need to open and close the window until you understand that the sash fits tightly and evenly into the frame.

The sash does not fit tightly enough to the frame

On the side of the handle on the side end of the sash there is a system of eccentrics, with the help of which the tightness of the pressure to the sash frame is adjusted.

They may have different appearance depending on the manufacturer, but the principle of operation is the same in all cases.

By rotating the eccentrics with pliers or a hexagon, you can adjust the required degree of pressing of the sash to the frame.

If you need to adjust the degree of pressing of the window sash to the frame from the hinge side, this can be done using the adjusting screw located on the lower hinge.

If this sash is a tilt-and-turn sash, then you can additionally adjust the sash pressure using the top hinge.

To get to the adjusting bolt located on the scissors near the top hinge, you need to open the sash and then, after first pressing the lock, set the handle to the ventilation mode.

If you need to press the sash against the frame, you need to rotate the bolt clockwise; accordingly, you can loosen the pressure by rotating the bolt counterclockwise.

Some types of fittings are regulated exclusively using the responds located on the side of the handle. The position of the strike plates is adjusted using a hexagon.

Helpful advice!

To increase the pressure of the window sash to the frame, you need to move the bar towards the street.

The frame also has hex-adjustable clamping mechanisms on the hinge side. The more you extend the tongue, the more the sash will be pressed against the frame.

The handle is blocked when the sash is open in the “closed” mode, the window does not close

In order to prevent damage to the hardware mechanisms, the handle can only be turned when the sash is closed. To prevent accidental turning of the handle when the sash is open, there are special lockers located under the handle at the end of the sash.

Depending on the manufacturer, they also come in different types. Before unlocking the handle, you need to press the lock.

The sash is closed, but the window does not close because the handle does not turn

If the handle does not turn after closing the sash, this means that the clutch of the lock with the counter element located on the frame does not work.

This problem can be solved in two ways:

1. Using the adjusting screw located under the lower hinge, move the sash slightly in the direction of the counter part of the blocker
2. Having slightly loosened the fastening, insert any thin plate of hard material between the counter part of the blocker and the frame

It also happens that a plastic window does not close at all (for example, if the window opened in two positions at once). What to do in this case? Read my article “Plastic window does not close - what to do?”

The handle is broken

In order to replace the handle of a plastic window, you need to slightly pull the handle cover towards you and turn it 90 degrees.

This usually happens due to insufficient lubrication. To prevent such a situation, it is necessary to lubricate the fitting mechanisms at least once a year. For these purposes, you can use aerosol lubricants or machine oil.

It is worth noting that monitoring the technical condition and lubrication of all mechanisms of window fittings must be carried out even in the absence of visible defects at least once a year.

If you are interested in adjusting plastic windows, it is useful to remember that:

• it is necessary to periodically check the condition of the rubber seals to prevent their wear;
• if you remove decorative plastic plugs, do it carefully, as they are very fragile; make sure not to deform them or crush them during the main work;
• if your frame or window opening itself is deformed, you will not be able to adjust the windows yourself;
• If you are not sure that you can do everything yourself, it is better to entrust the work to a trusted specialist. This way you can be sure that everything is done with high quality and you won’t need to redo anything.

I suggest watching a video that clearly shows how to adjust a plastic window with your own hands.
