Adjustment of plastic windows up and down. How to adjust plastic windows yourself - step-by-step instructions

Since the installation of plastic windows is very simple, anyone can install them themselves.

The only thing is that you must follow all installation instructions so that the window is installed correctly and lasts a long time.

It is important to keep the fittings clean, then they will last a long time. Especially a lot of debris collects from above after the window, platbands for plastic windows are installed and the slopes are finished. This debris should be removed immediately after all work has been completed.

The fittings that come with the windows are of high quality and ensure trouble-free operation throughout the entire operation of the plastic windows, if the windows were initially installed in a high-quality manner.

But over time, some problems are possible: drafts appear, noise from the street penetrates, and sometimes windows and doors begin to open with difficulty. The reasons for this may be different:

• horizontal and vertical adjustments were not made initially;
• natural wear and tear of structures;
• sagging of the valves;
• seal wear;
• loose clamping of the sashes, etc.

You can fix these problems yourself by adjusting the fittings.

The design of the fittings is well thought out, so self-adjustment does not take much time. How to adjust plastic windows is described in the instructions that come with them.

General information and necessary tools

To adjust PVC windows, you may need a hex wrench, pliers, flat-head and Phillips screwdrivers, and machine oil.

The most commonly used is a hex wrench, which is often called a furniture wrench. It is shaped like the letter "L".

Star-shaped attachments are rarely used, only for some types of fittings, but it is better to have them.

The fittings are attached to the window using bolts; to tighten them, you need a Phillips screwdriver. This screwdriver is used when installing the handle and adjusting it.

Any metal-plastic window works thanks to the lower and upper hinges, as well as eccentrics located around the perimeter of the sashes.

In order to know the cause of the problem and be able to eliminate it, you need to understand the operating principle of the main elements of the window. All window sashes can be adjusted in three planes, thanks to this it is possible to correctly adjust their position and pressure along the entire perimeter of the window.

Adjusting the sash position

Plastic windows usually have two hinges: top and bottom. The lower hinge serves for vertical adjustment of the sash, that is, it can be moved up or down, and it also allows horizontal adjustment, in which case the shift can be made to the right or left.

Before adjusting the lower hinge, it must be freed from the protective cap and a hexagon must be inserted into the hole.

If the window sash catches the frame from below, then it must be lifted upward; to do this, the key must be turned clockwise.

If it rubs from above, then it must be lowered; to do this, the key is turned counterclockwise.

If you need to adjust the shift to the right or left, in case of rubbing on the sides, use another adjustment hole, which is located on the side.

To get to it, you need to open the window. You can adjust the position of the sash by turning the key inserted into the hole.

If you turn it clockwise, the shift will be to the right. If you turn it counterclockwise, then to the left. The direction of rotation depends on where the frame hooks.

There is an adjuster in the top hinge, which allows you to adjust the sash to the right or left using the appropriate key.

By turning the key clockwise, the sash is moved to the right. If you turn the key counterclockwise, it moves to the left.

In which direction to shift depends on which side the sash clings to the frame.

Adjusting the sash pressure

If necessary, the sash is pressed. You can check the need with a piece of paper. To do this, insert it between the frame and the sash; it must be clamped tightly. If the sheet moves freely, then additional adjustment of the pressure is needed.

At the end of the sash there are oval eccentrics, which are part of the locking mechanism.

There are corresponding hooks on the frame. When the handle is turned to the “closed” position, a clutch occurs and the sash is pressed against the frame.

You can adjust the pressure with a wrench, and in some cases with plates located on the window sash. It depends on the design of the plastic windows.

The degree of pressure is adjusted using eccentrics. If you turn them to the left, the sash will be pressed more tightly against the frame. If you turn to the right, the pressure will be weaker. When turning the eccentrics, the distance between the frame and the eccentric changes.

The smaller this distance, the tighter the sash will be pressed. Eccentrics are located along the entire perimeter of the entire sash. Before you start making adjustments, you need to check the places where you need to do this.

It is necessary to turn the eccentrics literally a few millimeters so as not to press the sash too hard when closing. Strong pressure can lead to rapid wear of the seals. The ovals must be placed in the same position.

If the adjustment with eccentrics does not work, you can adjust the clamp using the mating part by changing its position.

The mating part is held in place by bolts that have a hole for a hex key.

To increase the pressure, you need to move the hook in the direction of the street, while loosening the bolts. To loosen the clamp, the hook must be moved towards the room.

The pressure can be adjusted with bolts located in the hinges if a transom system is used. Having freed the lower canopy from the cap, you can see the adjustment bolts. The bolt for adjusting the pressure is at an angle of 90 degrees to the plane of the window.

It is better to adjust it when the sash is closed.

To press the sash more firmly, you need to insert the hexagon into the bolt and turn it clockwise. If you need to loosen the clamp, then turn the key counterclockwise.

The pressure can be adjusted depending on the time of year.

In summer, the pressure can be loosened to provide better ventilation of the room. In winter, the pressure can be made stronger to better retain heat. If you adjust the pressure correctly, you can extend the life of the seals, since they will wear out less.

Replacing the handle and fixing problems

If the handle is cracked or you decide to replace it with a handle with a lock so that children cannot open the window, you need to follow certain steps. There is a base underneath the handle.

It must be slightly pulled back and rotated 90 degrees. Screws will open that need to be removed.

When the handle is installed and the screws are screwed in, the base returns to its previous position.

If the handle is difficult to turn, this may be due to lack of lubrication or sagging of the sash. In the first case, you can purchase special oil or use machine oil and lubricate all components.

It is useful to lubricate regularly. If the reason is sagging of the sash, then it must be adjusted using the adjustments located in the hinges, as described above.

There are situations when the handle is placed in the closed position, but the window does not close. This happens when the window is locked.

The lock is installed so that the handle can only be turned when the window is closed, thus protecting the mechanism from damage.

Lockers differ from one manufacturer to another, but are always located at the end of the sash under the handle. To unlock the handle, you need to press the locking tab.

Adjusting plastic windows yourself is quite simple, especially since instructions are always included with the windows, but adjustments must be made carefully so as not to overdo it.

It is important to monitor the condition of plastic windows and correct all problems in a timely manner, then they will serve for a long time. It is advisable to carry out adjustments twice a year when changing seasons.

During the period of operation of PVC windows and doors, there is a need for their periodic adjustment in connection with preparation for the summer or winter season or repair in case of wear. To do this, you can call a specialist to your home or perform all the adjustment work yourself. The first option is not always convenient, and in the second case, the lack of necessary skills may interfere. Therefore, let's take a detailed look at all the stages of adjusting PVC windows and doors and, based on the knowledge gained, prepare them for the winter period.

The design of plastic windows and doors - the need to adjust them

The design of plastic systems is a complex mechanism that requires scheduled maintenance or periodic repairs. Planned activities are carried out when the seasons change, when it is necessary to adjust the plastic windows before the onset of winter. Most often this concerns proper pressing of the sashes, elimination of friction, and replacement of the rubber seal.

Since we are more interested in how to properly adjust plastic windows and what to pay attention to when doing so, we will consider this case in more detail. Let's start by studying the structure of window systems. The main material for making metal-plastic windows is polyvinyl chloride. Compared to other materials, it has high performance characteristics and is resistant to various physical and chemical influences and temperature changes. Primarily daily and seasonal. A window or door block consists of the following elements:

• frame - a fixed section to which other elements are attached;
• sashes - moving parts that open in the horizontal and vertical planes;
• reinforcing profile, the location of which inside the frame gives the structure a certain rigidity;
• double-glazed windows (double-chamber ones retain heat better than single-chamber ones);
• window fittings - special mechanisms that ensure opening and fixing the sashes;
• impost necessary for closing the sashes;
• glazing bead - with its help the glass is securely fixed in the frame;
• ebb - serves to drain water and remove condensate from drainage holes.

The design of plastic doors is somewhat different from the window system. The main differences are as follows:

• instead of a double-glazed window, an opaque sandwich panel can be installed in the lower part;
• a mortise lock can be installed as a locking device at the customer’s request;
• due to the larger size and weight of the door, more powerful hinges are installed;
• For smooth automatic closing of the door, it is possible to install a closer;
• low tide is not established.

Otherwise, the design of windows and doors, both with simple and complex opening, has many similarities. For example, the presence of a locking mechanism consisting of locking rollers (eccentrics) located along the perimeter of the opening part of the sash, with the exception of the bottom. Operated by hand. Opposite the eccentrics with a slight offset on the impost and frame of the metal-plastic structure so that they close tightly , metal retaining strips are installed.

The rollers, driven by turning the window (door) handle, begin lateral displacement and engage with the slats, which ends with the sash tightly pressed to the window frame. When preparing plastic Euro-windows for winter conditions, the fittings are adjusted in such a way as to ensure the tightest fit of the sash and prevent the possibility of cold air entering the room.

To open the window, we carry out the reverse movement, which leads to a break in the connection. Before the onset of summer, the fittings are adjusted in such a way as to reduce the level of pressure on the sash and the sealing gasket. Large gaps compensate for the effect of thermal expansion in the summer, therefore, reducing the likelihood of deformation of the window unit.

Elimination of basic technical malfunctions of window systems

One of the reasons that prevents a window from closing tightly is friction. It usually manifests itself during operation by lowering the sash onto the frame, less often when it is shifted laterally. Opening and closing is difficult. In some cases, this leads to a loose fit of the window in its lower part and the formation of a gap through which cold air begins to enter the room. The Eurowindow is drafty. With further lowering, the resistance to the normal movement of the sash increases, which can lead to the formation of serious defects and cause breakdown. You can eliminate the defect yourself in one of two ways.

The first method consists of horizontal adjustment of the upper adjustment screw in the case when there is a lateral displacement of the sash in the horizontal plane, and its middle part touches the frame. Since the screw is located in the area of ​​the top hinge, its adjustment occurs with the sash fully open. Not to be confused with the “ventilation” position, in this case access to the adjustment mechanism is limited. We can adjust the lower horizontal adjustment screw in the “open” and “ventilation” positions. The adjustment range is (-) 2 mm.

To make the adjustment, we perform the following operations:

• open the door;
• in the upper end part we find the adjusting screw, it is located at the end;
• by rotating it using a hexagon, we move the sash in a horizontal plane in the desired direction - to the right or left;
• in the same way we adjust the adjusting screw on the lower hinge;
• We check how the opening and closing occurs and whether the “friction” has been eliminated.

The second method is to adjust the height of the sash in case of sagging. Sequence of work for adjusting the lower adjustment screw:

• remove the protective cap from the bottom hinge;
• we rotate the vertical screw in the direction we need, clockwise rotation raises the sash, counterclockwise - lowers it;
• Once the setup is complete, install a protective cap on the loop.

When setting up metal-plastic windows with your own hands, you should turn the screw little by little, literally half a turn at a time, constantly checking the functionality of the system.

Other common breakdowns and how to fix them

The handle turns with great effort. The reason may be contamination or lack of lubricant on the moving parts of the window system. In this case, take machine oil (you can use other oil, the main thing is that it is viscous) and use an oil can to apply it to all moving elements. The opening and closing mechanism located inside the window profile is lubricated through the upper technical holes. Or by unscrewing one of the top screws on the end side of the sash. Flowing down, the oil will evenly cover all moving parts and mechanisms with a protective film.

The handle is loose. Another common problem that arises during long-term use. To make repairs, we take and lift the decorative plate covering the base of the handle. Turn it 90° and gain access to the mounting screws. In this case, it is better to set the handle horizontally. Tighten the screws with moderate force, being careful not to damage the plastic holding the handle. Otherwise you will need to install a new one. Return the plate to its original position.

The handle is broken. In this case, it is advisable to purchase a new handle and install it yourself. To remove the broken handle, turn the protective plate and unscrew the fastening screws. We install the new handle and tighten the screws, return the plate to its place. If the handle turns tightly, lubricate the mechanism with machine oil or special oil for lubricating plastic window fittings.

It is necessary to adjust the pressure using eccentrics and trunnions. For repairs, you will need pliers or a hexagon. The adjustment of the clamping cylindrical pins with a hole for a hexagon (eccentrics) is carried out with a hexagon, pins without holes (trunnions) - with pliers.

When closing the sash, the cylinders engage with the strikers and press it securely. Adjustment is carried out in two directions:

• Vertical - the clamping force decreases, which is better suited for summer mode.
• Horizontally – the clamping force increases, which is better suited for winter mode.

When setting up for winter, it is important to make adjustments so that it does not blow. To do this, place a sheet of paper around the perimeter of the sash under the rubber seal. We close the window and try to pull out the paper. If it comes out freely, it means the seal is not tight. We open the sash and, by rotating the eccentric (trunnion) in the desired direction, strengthen the pressure. We close the sash and again check the clamping force using a sheet of paper. We repeat the operation until the sheet is securely held by the seal. Using this method, we check the clamping force along the entire perimeter of the sash.

When adjusting the trunnions with pliers, in order not to scratch the surface of the pressure cylinder, it is necessary to place a soft cloth!

The rubber seal has become unusable. The sash is closed and pressed tightly, but air movement is felt between the window and the frame. If it was not possible to fix the problem by adjusting the eccentrics, then this indicates wear of the rubber seal and a decrease in its elasticity. The correct thing to do is replace it with a new one. This can be done without outside help.

Remove the old seal from the groove. We mark the new seal strictly according to the dimensions of the old one, preferably a little larger. This will allow the ends of the seal to fit tightly to each other at the joints, since installation should be done without tension. We place the rubber strips in a special groove and press it in, achieving a tight fit. Finally, we fasten the ends of the seal at the junction with glue.

To prevent drying and cracking of the rubber seal and to extend its service life, it is recommended to periodically treat its surface with silicone grease.

Instructions for adjusting balcony doors

The adjustment occurs according to the same scheme as in the case of plastic windows. We discussed the main points above. In addition to seasonal adjustments, sometimes there is a need for unscheduled repairs. For example, in cases where:

• The door leaf is closed, but it “sees through” and does not block the air movement.
• When opening and closing the door, it touches the door frame, requiring additional effort.
• The door handle turns very tightly or, on the contrary, becomes loose.

Scheme for adjusting the balcony door in three planes:

• Vertical, allowing it to be raised or lowered.
• Frontal, that is, when the clamping force is adjusted along the entire perimeter.
• Horizontal, allowing you to move the door to the left or right. The adjustment screws are located in the area of ​​the upper and lower hinge.

So, we looked at how to properly, and most importantly, independently carry out repairs or seasonal adjustments of windows. We hope that after reading the proposed materials and instructions, it will not be difficult for you to carry out minor repairs and adjustments on your own. And thereby improve living conditions and extend the service life of window and balcony systems.

Plastic windows and doors differ from other options in their practicality in operation and provide an optimal microclimate in the room. In this case, the structures need adjustment, which involves adjusting the mechanism depending on the situation. For this, there is a certain technology that allows you to independently make plastic doors and windows even more convenient and functional.

The need for the procedure

Plastic doors and windows are airtight and prevent dust, moisture, and cold from entering the room. As a result, they become practical for living spaces, but require periodic adjustment of the mechanisms.

Adjustments are made as needed

When manufactured at the factory, windows and doors are adjusted in height, taking into account the pressure against the frame and the inclination. After installation, the product does not require special operation, but over time the mechanism wears out, the fastenings become loose and the need for adjustment arises. This process may be required in the following cases:

• disruption of easy movement of the sash, jamming of the mechanism when opening/closing;
• loose pressing of the sash to the frame, penetration of cold air;
• loosening of the handle mechanism;
• change from cold to warm season;
• sagging window or door sash.

There are situations when even professional adjustment does not allow returning the functionality of a plastic product and serious repairs are required. This is necessary if the quality of the fittings that were used to install the product is poor. Incorrect assembly during installation also causes breakdowns. Such defects cannot be eliminated on your own and require the help of a specialist.

Features of adjusting windows and doors from different manufacturers

Many factories produce plastic windows and doors, characterizing their products as easy to use and durable. Promotional offers often contain information about various unique technologies that distinguish products. All this may be a marketing ploy, since the designs of finished plastic windows and doors from different manufacturers are practically the same.

Plastic windows from any manufacturer require regular maintenance

REHAU products are characterized by high quality, but they also require adjustment during operation. The features of this process for REHAU brand products are expressed as follows:

• the internal mechanism of doors and windows can be adjusted in several planes, that is, down and up, right and left, as well as with pressure adjustment;
• if the structure is equipped with fittings from the Siegenia Aubi brand, then to adjust it you need to tighten the screws;
• if there are MAKO brand fittings, then you need to remove the sash and then carry out adjustment work;
• REHAU blitz products use Roto fittings, which require hex keys to operate.

Fittings from different brands require different approaches to repair.

One of the well-known manufacturers is Veka, which produces modern doors and windows. When setting up such products, take into account the following features:

• to switch the structure to winter mode, you need to turn the closing tenon by 90° using a hexagon, located under the top turn;
• if the sash is closed, but the handle does not turn and it is impossible to close the window, then you should slightly move the sash towards the counter zone of the blocker, using the adjusting screw located under the lower hinge;
• If the handle breaks, you need to turn the decorative trim 90°, unscrew the screws and remove the old element.

Windows and doors have similar design mechanisms

KBE brand products are of high quality, but require timely adjustment. To do this, you need to pay attention to the following design features:

• the tightness of the fit of the canvas to the frame is adjusted by three eccentrics located on the end part of the sash;
• to eliminate sagging, adjust the screws on the upper canopy, that is, loosen the lower one and turn the upper element to the right or left;
• The broken handle is removed by removing the lining and unscrewing the bolts.

The design of windows from different manufacturers is similar and does not require complex tools for adjustment.

Products from different companies differ only slightly in the shape of the control parts and their location. The operating principle of the mechanisms is the same, and therefore it is not difficult to adjust the operation of the system with your own hands.

Self-adjustment of plastic doors and windows

To carry out self-adjustment, you will need tools such as hex keys, flathead and Phillips screwdrivers, as well as pliers and mechanical lubricant. The process can be completed in a short period of time by following the instructions and using quality tools.

Adjusting doors and windows allows you to create a comfortable indoor microclimate

How to set summer-winter mode

Setting the summer-winter mode of windows and doors is similar and is necessary when the season changes. In summer, after adjustment, the sash turns out to be less pressed against the frame than when setting the winter mode. In hot weather, this ensures that air enters the room through micro-holes. If you constantly use the winter mode, which is characterized by very tight pressing of the sash to the frame, the seal will quickly wear out, and the room will be stuffy during the heat. Thus, the difference between these two modes lies in the compression density and the degree of tightness of the structure.

To control the mode you need to perform the following actions:

1. At the side end of the door or window sash, in the handle area, there is a system of eccentrics, which are an adjustment tool.

   The eccentric allows you to adjust the pressure of the sash to the frame

2. A hex key whose diameter corresponds to the parameters of the element is inserted into the eccentric hole.

   A hex wrench is the main tool for controlling window or door mechanisms.

3. Next, slightly turn the eccentric a few millimeters to weaken (summer) or strengthen (winter) the pressure of the sash to the frame. It is important to do this carefully and without sudden movements.

   For the demi-season, you should only slightly adjust the rotation of the axles

4. To easily correct the pressure in the autumn or spring, you need to rotate the element very slightly, which should take the standard position.

   The mechanisms may differ in appearance, but they work on the same principle.

Setting the sash pressure

In case of drafts or loose pressure in the hinge area, the mechanism is adjusted, for which you will need a 4 mm hex key. First you need to determine the area from where the strongest blowing occurs. This is necessary to configure the lower or upper loop.

The work package involves the following actions:

To adjust the sash in a vertical position, use the lower hinge. A cap is opened on the hinges, which provides access to the mechanism and the hex hole.

After removing the cap, the mechanism of the blade is visible

The canvas can be adjusted in horizontal or vertical positions. If the hexagon is rotated clockwise, the window is pulled closer to the frame, otherwise it only works to loosen the fixation between the panel and the sash, that is, to lower its lower area. Adjustment on the top hinge is only carried out with the sash fully open. In this case, it is impossible to move the window by more than two millimeters.

Using a hexagon, adjust the hinges to the desired result

1. When setting the clamp for the first time, it is important to only slightly turn the hinge mechanism with a hexagon. After several years of operation, the elements of the system wear out as a result of opening/closing and the rotation can be increased.

How to adjust the handle of a plastic window or door

The handles of modern metal-plastic doors and windows are subjected to intensive and not always correct use. To avoid damage, this element should be rotated only when the sash is pressed tightly. If the handle malfunctions, the following measures will help solve the problem:

• To replace the old element with a new one, turn the decorative cover 90° and remove it after unscrewing the screws. The mechanism is removed and a new one is installed, returning the screws and cover to their place;

  A new pen can be easily purchased from the manufacturer

• If the handle is in the closed position, but the window cannot be closed, then the mechanism is blocked. The design includes a special lock designed to prevent the handle from being turned in the open position. To unlock, press the lock located at the end of the sash, then close the leaf and turn the handle;

  Blockers from different manufacturers differ in appearance, but have the same operating principle

• Difficult turning of the handle is often due to insufficient lubrication of the mechanism. To fix the problem, you need to remove the decorative panel, unscrew the screws and slightly pull out the mechanism, onto which aerosol or machine lubricant is then applied, and the excess is removed with a napkin.

  After lubrication, the handle is put back in place.

Adjusting plastic balcony doors

Despite the fact that the window and door sash designs are similar, the mechanism settings have slight differences. Position correction can be carried out vertically, in which the height of the canvas relative to the opening changes. Horizontal adjustment allows you to correct the gap between the sash and the hinges, and with the help of front adjustment you can set the optimal pressure of the leaf to the frame.

The implementation of these options for adjusting the mechanism involves the following actions:

• For horizontal adjustment, you need to remove the decorative trim from the hinges, install a 3 mm hex key in the adjusting screw and turn it clockwise 1 or 2 times. This is done for each of the loops;

  The hinges are adjusted using a 3 mm hexagon

the vertical screw allows you to slightly move the blade up (you need to turn the element clockwise) and down (counterclockwise). This option is optimal if the lower leaf of the balcony door rubs against the threshold when moving, and also if, during normal closing, defects have arisen on the upper or lower rubber seals. To work, you will need a 5 mm hex key. A similar 2.5 mm hexagon, as well as a flat-head screwdriver, are necessary to correct the placement of the lower and upper opening slats. A Phillips screwdriver is used to adjust the main linings;

Setting up a PVC balcony door is carried out according to the principle of window adjustment

• if frontal correction of the door leaf is required, then for this you need to follow the technology of pressing the door against the frame, since these measures provide an equal effect.

  After setting the door there should be no drafts

Rules for caring for PVC doors and windows

Plastic structures are unpretentious in operation, but still require simple maintenance rules. One of them is that the system mechanisms require regular lubrication. For this purpose, use machine oil or WD40 aerosol, which are applied in small quantities to the mechanism.

Additional features of care and operation are expressed as follows:

• Glasses need to be washed with special products and soft cloths. There are kits on sale for the complete return of plastic doors or windows, which include all the necessary components;
• the entry of foreign objects into the frame space is unacceptable, as it leads to breakdowns that cannot be repaired independently;
• Do not rub the surfaces of PVC systems with hard sponges, because this will cause scratches and the appearance of the structure will be lost;
• after installation, it is best to install slopes that will ensure tightness and prevent damage to the polyurethane foam used to seal cracks;
• Complete replacement of double-glazed windows, sashes, window sills and other parts is carried out only by professional craftsmen, and the elements must be ordered from the manufacturer.

Proper operation significantly extends the service life of PVC windows and doors

During operation, do not place hot, sharp, or heavy objects on the windowsill. The window or door serves to provide comfort, is fully assembled and does not require additional treatment with silicone sealant or other similar means. Sheathing, painting and other measures are unacceptable for these systems.

Adjustment of PVC doors and windows is carried out when problems arise that you can fix yourself. Compliance with operating technology and accuracy when setting up will ensure a long service life of the structures. This also allows you to maintain the characteristics and functionality of the systems, that is, tightness and good sound insulation, which is important for many rooms.

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

Do you want to know how to adjust the sash pressure and how to eliminate other minor defects that negatively affect the operation of the window structure?

Read the tips contained in the article.

More information about plastic windows

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

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

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

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

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

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

• screwdrivers with flat and Phillips profiles;
• hex or star wrenches (usually marked with the numbers “5” and “2.5”);
• pliers;
• metal ruler or tape measure;
• pencil;
• building level;
• seal made of polyvinyl chloride material;
• construction adhesive that allows 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 there is no specific scheme according to which the pressure of plastic window sashes should be “adjusted”. As a rule, such adjustment is carried out intuitively.

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

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

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

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

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

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

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

Elimination of other problems of plastic windows

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

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

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

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

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

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

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

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

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

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

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

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

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

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