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 adhere to certain rules by using these windows, they will last two or even three times longer;
• high level 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 periodically painted, unlike wooden ones;
• The versatility of the window is ensured by such functions as the possibility of its ventilation, 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 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 kinds 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 does not enter the room and cold air. If there are two or more windows 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. Plastic version 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 bottom part doors 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 manufacturing company has individual characteristics window settings.

The work of adjusting plastic windows is carried out by professionals, however, subject to certain rules, it is possible to self-execution. In order to adjust the plastic window, mandatory You will 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.

Adjustment of the window on the top hinge is carried out only when full opening windows. 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 steps, it is possible to get rid of drafts in the room and heat losses in winter time year.

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 clamping parts of the handle. 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 summer time years when indoors is required fresh air, the pressure is weakened, and in winter, to prevent heat loss, the pressure is strengthened. 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 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 period of use of the window, it is necessary to increase given value. 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 old pen 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 troubleshoot problems initial stage their formation rather than replacing damaged parts or doors.

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. 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 for adjusting and repairing 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 hardware design different manufacturers. Now let's imagine 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 suggests 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 the bottom up, 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. Window device will not be able to open and recline 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 strip 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 appearance eccentrics are different, 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 pressing of the sashes in summer and winter period different. 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. Special attention should be given to the swing-out flap. Setting up folding mechanism 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 strikers 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 look at other cases where adjustment is needed window fittings. 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.

In case of certain malfunctions of the handle, a situation may arise when the handle is turned in the “closed” position, and the structure is open. That is, the blocker fixed the position of the handle. To correct this situation, you must press the locking device and turn the locking mechanism to the “open” position.

The handle doesn't turn

How to adjust plastic windows with your own hands if problems arise with the handle? It jams or it is impossible to turn it.

With such a defect, the process of coupling the locking mechanism with the mating element is not carried out. This problem can be solved in two ways:

• the sash is moved using an adjustable screw to the response mechanism;
• the fastening is loosened and a plate of dense material is inserted between the sash and the frame.

The handle is broken

If the handle fails, you can repair the plastic windows yourself. Repair begins with the mechanism locking device released by removing the cover.

To do this, you need to pull it back a little and turn it 90 0. Next, you should unscrew the fasteners that hold the device in place, and install a new handle in its place. For more information on adjusting the handle, watch this video:

The handle turns poorly

Mechanical adjustment of plastic window fittings is not always necessary. For example, poor functioning of the handle of a plastic window is mainly due to poor lubrication of the mechanism.

1. Check seals regularly to prevent wear.
2. When removing all plugs, work should be done very carefully so as not to spoil their appearance.
3. If the frame is deformed, you will not be able to adjust the windows yourself. IN in this case you will have to turn to specialists. It is better not to repair PVC windows yourself.

An important factor in the long-term functioning of metal-plastic structures is the installation of products from generally recognized manufacturers. For example, install “Rehow” windows in your home; the quality of these products has been tested over the years. For more information about adjusting a PVC window, watch this video tutorial:

To avoid the appearance of defects in the fittings of plastic windows, all rubbing parts should be regularly lubricated.

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

More information about plastic windows

Plastic windows - realities modern houses. 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 simple process, which can be handled by any person who has held a screwdriver at least once in their life and knows the difference between a hex and a star wrench.

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 plastic parts to be held together, or liquid plastic that hardens after some time of 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 double-glazed windows

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 a certain scheme, according to which the pressure on plastic window sashes should be “adjusted” does not exist. As a rule, such adjustment is carried out intuitively.

To increase the pressure plastic doors, 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 containing 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 locking mechanisms windows are initially static, 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, you should pick up and temporarily remove 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 solutions for oil based(for example, with 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.

Nowadays, the popularity of plastic windows is no longer in doubt, because they not only have high quality, but also an affordable price. Not to mention that they are easy to use and provide excellent noise protection. But despite this, even the most quality windows require maintenance, so from time to time it is necessary to call a specialist to adjust them. Many people wonder: “Is it possible adjustment of plastic windows without calling the master? 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 window problems can you 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
• The handle is very difficult to turn

For repairs we may need the following tool:

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

Almost all doors modern windows PVC can be adjusted in three planes, thanks to which it is possible to 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 sashes.

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.

Figure 1 - General principles for adjusting PVC windows

Figure 2— General scheme plastic window adjustments

Figure 3 - Various options window adjustments

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

How and how to adjust a plastic window for various malfunctions

1. 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:

2. When closing, the sash touches the side of the frame

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

3. 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 will need to open the window, remove the plastic plugs from the adjusting bolts (they are located on the bottom and top hinges, on the same side as the sash) and using a hex wrench (four mm) 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.

4. 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.

Figure 7 — Adjusting the pins of plastic windows

By rotating the eccentrics with pliers or a hexagon, you can adjust the required degree of pressing of the sash to the frame. IN summer period It is recommended to use weak pressure, and strong pressure in winter. 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 (Figure 8).

Figure 8 — Adjusting the window pressure

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 (Figure 9), you need to open the sash and then, after first pressing the lock (Figure 11), 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.

Figure 9 — Adjusting the pressure of a PVC window

Some types of fittings are regulated exclusively with the help of responders located on the side of the handle (Figure 10 - a). The position of the strike plates is adjusted using a hexagon. To increase the pressure of the window sash to the frame, you need to move the bar towards the street. The frame on the hinge side also has hexagon-adjustable clamping mechanisms (Figure 10 - b, c). The more you extend the tongue, the more the sash will be pressed against the frame.

Figure 10 — Adjusting the window pressure using rivets

5. 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 various types(Figure 11). Before unlocking the handle, you need to press the lock.

Figure 11 — Locking in “closed” mode

6. The sash is closed, but the window does not close - the handle does not turn

If, after closing the sash, the handle does not turn, 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, slightly move the sash in the direction of the counter part of the lock (Figure 6)
2. Having slightly loosened the fastening, insert any thin plate of hard material between the counter part of the blocker and the frame.

It happens, it happens that The plastic window doesn't close at all(for example, if the window opened in two positions at once). What to do in this case? Read my article

7. 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 (Figure 12). Next, unscrew the screws, remove the old handle and install a new one in its place, set the trim to its original position.

Figure 12 - The window handle is broken - how to remove and replace?

8. The handle is very difficult to turn

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 adjustment of plastic windows, It's useful to remember that:

• it is necessary to periodically check the condition of the rubber seals to prevent them from wearing out;
• if you remove decorative plastic plugs, do it carefully, as they are very fragile; be careful not to deform them or crush them during the main work;
• if your frame or itself is deformed window opening, then you won’t 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.

VIDEO: How to adjust a plastic window (PVC window) with your own hands

How to tighten plastic windows so that there is no draft from the sash? This question interests every owner of an opening double-glazed window. Indeed, in the cold season, even a small gap between the double-glazed window and the frame leads to a loss of comfort in the house.

How does the double-glazed window sash mechanism work?

A plastic window consists of a polymer frame (sometimes with a sash), a multilayer package assembled from 2-3 glasses separated by a void (air is the best heat insulator) and a mechanism that ensures the opening and closing of the window.

The mechanism of the sash allows you to swing it open by turning it on its hinges, or tilt it back, opening it at a precisely adjusted angle. To ensure these actions, the following components are included in the double-glazed window mechanism:

• Top loop - complex element, providing both rotation and tilting.
• The bottom loop is a simple element that provides only rotation.
• The lock is a complex unit that both locks the sash and adjusts the functionality of the top hinge.

How the window will work - tilt or open - is decided by the constipation. When its handle (lever) is moved down, parallel to the side of the frame, the window closes tightly. Rotating the lever 90 degrees unlocks the swinging function - the window can be opened by pulling the handle towards you. Rotating the lever 180 degrees unlocks the tilting mechanism - the window will open slightly under its own weight or due to muscular force.

When do you need to adjust the window sash?

Firstly, adjustment is needed in case of errors during window installation. Insufficiently qualified craftsmen may make a mistake when checking the horizontal or vertical position of the glass unit, after which the sash will begin to scratch the frame. In this case, you will need a 2-3 mm adjustable gap in height and width.

Secondly, adjustment will be useful after several years of window operation, when the seals lose their elasticity or simply wear out. The sash will be pressed against the frame, but the worn seal will no longer seal the joint. Then the millimeter adjustable clamping gap will come in handy.

Thirdly, manual adjustment of the gaps will be needed when the seasons change. In winter, everyone wants perfect tightness of joints (so that there is no wind), and in summer no one will refuse a slight draft.

Moreover, even in winter, before tightening the plastic windows, it is necessary to provide for the existence ventilation gap, providing a flow of fresh air into the insulated room. Therefore, further in the text we will look at adjusting windows that blow either too strongly or very weakly.

Preparing a window for winter: how to adjust a plastic window so it doesn’t blow

If the sash scratches the frame, then in winter there is a blow from the window due to the distortion of the structure. To eliminate this drawback, you will have to do the following: slam the window and lock it with the handle. After this, grab the edge of the sash with both hands and pull it towards you, without offering much force. If it moves out of place at the bottom, then you have a loose bottom hinge. If it's at the top, you have problems with the top hinge.

After localizing the location of the displacement, you need to start eliminating the distortion. The loop at the bottom is adjustable both vertically and horizontally. The upper mechanism can be adjusted in the same way. The tool usually used is a 4mm hex wrench. Sometimes a cross-head screwdriver or a special star wrench included in the window delivery kit is used.

To adjust horizontally, open the sash and insert the key into the groove located at the bottom of the hinge. Turning clockwise brings the glass unit closer to the hinge, turning in the opposite direction moves it away.

Vertical adjustment of the lower hinge is performed differently: the window is opened slightly, tilted into the room, the key is inserted into the groove located in the end part of the curtain. Turning clockwise raises the sash, turning in the opposite direction lowers it. After completing the adjustment, you can close the window and check whether the sash moves away from the frame or not.

The hinge at the top of the window is adjusted slightly differently. To do this, you need to open the window 180 degrees and get to the adjusting screw located on the side of the sash, in the area of ​​the top hinge. Next, insert a key into the head of the screw and turn it a quarter turn. After this, close the window and check the degree of pressing of the sash again. If necessary, the operation is repeated.

If the screw at the top hinge does not help, then it is necessary to adjust another unit, which is located in the area of ​​the tilt mechanism plate that holds the window in an inclined position. To do this, open the sash and, holding the lock, tilt it back, gaining access to the plate at the top of the window. Next, insert a key into the head of the screw and turn it a quarter turn clockwise or in the opposite direction.

To get to the tilt mechanism plate, you need to do the following: turn the handle 90 degrees, open the window, press the lock with your finger and turn the handle up 180°. After this, the open sash will tilt towards the room, exposing a plate with an adjusting screw.

If the sash closes easily and without squeaks and does not move when closed, but there is still a draft coming from the windows, tighten the clamp of the glass unit to the frame. To do this, do the following:

• Open the frame and turn the locking handle down. In this case, part of the metal pins protruding from the sash moves out of place. These parts must be marked with a felt-tip pen.
• Next you need to take pliers (for smooth surfaces) or a flat-head screwdriver (for a slot) or a hex wrench (for an internal recess) and turn the pins sequentially so that most of them move towards the seal.

Typically, to create additional clamping force, the pins are turned clockwise half a turn. Moreover, until the manipulations with all the pins that move when the handle is closed are completed, the sash should be kept open. You will be able to evaluate the results of your efforts only after completing this work. Otherwise, the window will warp on the locking elements.

Adjustment does not help - change the seals

In particular difficult cases To eliminate an unwanted draft, in addition to adjusting the sash mechanism, it is necessary to replace the seals. To do this, you need to open the window and fix the sash. Next, grab the seal and pull it towards you. With enough force it will come out of the groove very easily.

The next stage is the installation of a new seal. It starts with cutting to size. Moreover, the old seal acts as a template, so it cannot be stretched when dismantling. After trimming new material pressed into the groove and checked for the absence of creases and other defects.

According to manufacturers' recommendations, such a replacement should be done no more than once every 10 years, but the seal could be installed unevenly or damaged due to use. Typically, the main cause of damage to the seal is abuse of the sash pressure setting. Therefore, sometimes it is changed before the end of the 10-year period.

If the seal squeaks, then instead of replacing it, you should try silicone grease– it will remove the unpleasant noise. In this case, it is strictly not recommended to use machine oil.

Preparing a window for summer: how to create a light draft

Before this, we figured out how to tighten the hinges on plastic windows so that cold air does not blow from the sash. Now we have to solve another problem - to create a light draft that will blow through the stuffy room. To do this you need to do the following:

First, find the trunnions on the side surface of the sash - the moving parts of the clamping mechanism. Their details protrude above the surface more than other elements.

Secondly, inspect the trunnions and find eccentrics - special screws screwed into the trunnions with a center offset. They will give themselves away not only by their slightly uneven location, but also by the presence of marks (marks) on the screw head.

Third, turn the off-center screw in the desired direction. The standard position of the eccentric is exactly in the center of the trunnion, which gives a pressure of medium force. However, in summer we need the weakest clamp so that fresh air can enter the apartment. Therefore, we rotate the eccentric so that its smaller side faces the rubber band (seal). Typically, this is done by turning the screw counterclockwise by half or a quarter of a turn.

The described operation will have to be done with all the trunnions, setting the eccentric marks in one direction, otherwise the sash will begin to squint when locked, and its mechanism will wear out prematurely.
