Do-it-yourself adjustment of plastic window fittings. Adjustment of double-glazed windows and plastic window sashes

Adjusting plastic windows is necessary at the beginning of the winter and summer seasons and is within the power of everyone

The main adjustment of plastic windows is carried out by specialists during their installation. But over time, even on high-quality frames and sashes, some problems may appear related to violations of operating techniques or deformation of fasteners, moving mechanisms, and seals.

Most often, issues of adjusting plastic windows have to be dealt with in the following cases:

• seasonal changes in clamping density to ensure comfort in different conditions (winter-summer);
• the appearance of drafts if air is blown in from the street through tightly closed windows;
• sagging or displacement of window sashes, which leads to friction and catching on the frame;
• malfunctions in the operation of window handles, when they do not hold well, do not turn completely, or do not open (do not close) at all.

Many of these problems can be easily resolved by adjusting the plastic windows yourself. If you are unable to determine the cause or believe the problem is serious, it is best to seek help from a window repair and maintenance professional.

If you are not confident in your abilities, it is better to pay a specialist for routine repairs than to later buy new parts or completely change the broken window structure

For those who have sliding windows and doors, if there is a malfunction in their operation, it is enough to adjust the roller carriages intended for fastening the sashes. If your sashes open or tilt and you decide to adjust the plastic windows yourself, you will need some tools.

Prepare immediately:

• set of hex keys. First of all, you will need a hexagon with a diameter of 4 mm, which is often called a furniture key, as it is used when assembling furniture;
• a 3 or 4 mm Phillips screwdriver, preferably with a star bit (usually marked T or TX);
• pliers (pliers);
• a lubricant with machine oil and WD-40 all-purpose aerosol lubricant.

To adjust the window yourself, you will need tools. The photo shows a set of hex keys of different diameters

Hexagons are small metal rods bent into an “L” or “S” shape. The shape of the key is not important, but S-shaped ones are considered more convenient to use. Star attachments may be required when adjusting plastic windows with fittings of certain brands and models. Basically, craftsmen attach all the fittings using ordinary screws and screws, for which a Phillips-head screwdriver will suffice.

Adjusting plastic windows for winter

Before the onset of cold weather, many people want to make sure that the windows are closed more tightly and do not allow the slightest cold draft into the house. If the sash is pressed weakly, you may find that the flame of a lit candle or match brought to a closed window fluctuates greatly and even goes out.

The photo shows the end side of a window sash with fittings; the pressure adjustment mechanisms are clearly visible.

The clamping mechanisms are called locking pins (eccentrics). When the handle is turned to close the sash, they move behind the pressure pads located along the perimeter of the frame. Each sash usually has three eccentrics, which are set to the same position (by default - in the middle, universal position). To strengthen or loosen the pressure, they need to be rotated and moved. This adjustment of plastic windows is not difficult to do.

In different models of fittings, the trunnions can simply be turned using pliers or a wrench (standard), and also have a hole for a hex key. Some models use mechanisms that are adjusted without tools at all - the eccentric is pulled out by hand and locked in the desired position.

If you move the eccentric rollers, turning them clockwise, the sash will be pressed against the frame more strongly, and if it is counterclockwise, it will move away from the frame, reducing the pressure. There are often small stripes on the surface of the trunnions, which make it easier to determine the degree of pressure. The closer the strip is to the seal, the stronger the pressure on the sash. The adjustment range of the trunnions is ± 2 mm. In some designs of window fittings, the clamping density is adjusted by twisting special plates located on the window sash with a key.

In addition, there is a clamping mechanism on window hinges. There it is also adjusted using a hexagon. When the key is rotated (counterclockwise when the hinges are on the left, or arrow when the hinges are on the right), the tongue extends, increasing the pressing density of the sash. On the hinges, the clamping adjustment stroke is ± 0.8 mm.

When preparing for the winter period, it is better to maximize the density of the window sashes to the frame.

In the summer, it is recommended to loosen the pressure to a medium or minimum value in order to provide greater air access and reduce wear on the seals. When making adjustments, it is important to ensure uniform pressure along the entire perimeter of the window, so each pin must be twisted in the same direction and set to the same position.

Professionals in the repair of plastic windows warn that it is better to adjust the pressure density in the minimum ranges, especially for the first time. The fact is that the seals on the sashes wear out over time, dry out, and you have to press harder and harder. If you squeeze them too hard from the very beginning, the rubber will lose its properties much faster. Then the situation will be corrected not by adjusting the pressure, but by replacing the sealing tape. By the way, there is nothing complicated about this: the old rubber is removed, and the new one is inserted into a special groove.

A worn rubber seal is easy to replace: the old rubber is removed and the new one is inserted into a special groove

To do everything correctly, we recommend that you additionally look at what the trunnions (eccentrics) look like and how the sash pressure changes when adjusting plastic windows in the following video. This will make it easier for you to carry out the necessary preparation of windows for the winter season.

Sometimes it happens that the sashes move a little, lower, begin to sag and rub against the frames below or on the side when opening and closing. This problem can lead to complete structural failure, requiring window replacement. Small adjustments will allow you to solve it, which you can handle with your own hands in literally half an hour.

Let's look at how to make this adjustment of plastic windows yourself. Instructions for beginners:

1. Open the window. Locate the adjustment screw at the end of the sash (usually it is located closer to the top).
2. Take a suitable hex key and use it to turn the screw clockwise when you need to raise the sash mechanism, or counterclockwise to lower it.
3. Check whether the window operation has changed when closing and opening. If the situation improves, adjust it in the same way until it is completely corrected.

All tightening of the screw should be done little by little, with minimal adjustments, constantly checking the functionality of the window.

This method allows you to adjust plastic windows by pressing the sash to the horizontal plane, eliminate the distortion or move it by ±2 mm (range of permissible adjustments). If there is no positive result, you need to return the adjusting screw to its original state and try another option.

Do not forget about the adjusting screw, which is located under the protective cover (cap) of the lower hinge

To eliminate friction between the sash and the frame, vertical adjustment (with a stroke of ± 2 mm) of the window is also used, for which the lower hinge screw is responsible. You can get to it both from inside the house by opening the sash, and from the outside with the window closed. Procedure:

1. Carefully remove the protective cap from the bottom hinge.
2. Rotate the adjusting screw in the desired direction (clockwise – the canopy rises, counter-clockwise – lowers), turning it half a turn with a hex key.
3. Check how the window works. Adjust further if necessary.

For clarity, we offer the following video:

Doors that provide different modes of ventilation, that is, folding doors, sometimes require reinforcement of the structure from the canopy side.

Window flap in ventilation mode

Adjustment of plastic windows that move only along the vertical axis is done by tightening the adjusting screw on the lower hinge. It is located horizontally, that is, perpendicular to the plane of the window. If the design involves winter (micro-slot) ventilation, then you will also need to adjust the top hinge. The step-by-step instructions are as follows:

1. Open the window flap.
2. Turn the knob to the ventilation mode position. Some window models are equipped with locks (in the form of a lever or clip), which are responsible for tilting the sash only from the closed position. In this case, you need to press the lock and simultaneously turn the handle.
3. The pressure of the upper flap is adjusted with a screw or hexagon, which must be turned clockwise (to tighten the fit) or counterclockwise (to loosen the system). Allowable adjustment stroke ±2.5 mm.

Important: when adjusting the top hinge in ventilation mode, hold the window sash, as it will only be fixed on one bottom hinge.

Adjusting the handles

Problems with handles on plastic windows and doors arise quite often. Let's look at how we can fix them.

The handle doesn't hold tightly

When the handle dangles, it is necessary to tighten the fastening screws. To do this, the plug under the handle is turned 90° and the screws located on the plate under it are tightened with a suitable screwdriver.

Typically, fasteners have a slot for a Phillips screwdriver

The handle is difficult to turn

A common cause of such troubles is insufficient lubrication. Accordingly, to eliminate them, you need to lubricate all moving parts (eccentric rollers, hinges, clamping mechanisms and platforms) with machine oil. After this, it is recommended to remove the plug under the handle, use a screwdriver to find out where there are difficulties in the movement of the roller, and adjust them by tightening the screws.

For lubrication, use universal aerosols or machine oil, which is applied from an oil can, using a brush or a cotton swab.

The handle doesn't turn

Sometimes it happens that the handle rotation locks fix its position when the window is open. In such a situation, you need to pay attention to the fittings, or rather to the locking lock itself. For models marked AUBI, you need to point the sash vertically, press the metal plate with the spring and move the handle to the desired position. Other models (ROTO, GU, etc.) are adjusted by a metal tab located directly under the handle. You need to press on it and turn it parallel to the sealing gasket.

The handle is broken

It's easy to replace a broken handle yourself. New ones are sold in window manufacturing companies as component parts. On the old handle, turn the decorative cap to get to the mounting screws. They are unscrewed, a new handle is installed and screwed into place with the same screws.

Main window adjustment points

To summarize, let us once again list the main points for adjusting plastic windows:

• on the lower hinge there are screws that adjust the position of the entire sash vertically and the lower corner of the sash horizontally;
• on the upper hinge the clamping force is adjusted and the upper part of the sash is leveled horizontally;
• The eccentric locking pin on the end surface is responsible for adjusting the tightness of the window sash against the frame.

When starting to adjust plastic windows, check all the listed points for possible deformation. If they break, call a repairman immediately. If debris is found in the moving mechanisms, clean and lubricate, and then check how the window works.

Stretch ceilings made of PVC film can withstand from 70 to 120 liters of water per 1 m2 of their area (depending on the size of the ceiling, the degree of its tension and the quality of the film). So you don’t have to worry about leaks from neighbors above.

Before removing various stains from clothing, you need to find out how safe the selected solvent is for the fabric itself. It is applied in a small amount to an inconspicuous area of ​​the item from the inside out for 5-10 minutes. If the material retains its structure and color, you can move on to stains.

Threads made of gold and silver, which were used to embroider clothes in the old days, are called gimp. To obtain them, the metal wire was pulled for a long time with pliers to the required fineness. This is where the expression “to drag out the rigmarole” came from - “to do long, monotonous work” or “to delay the completion of a task.”

Fresh lemon is not only suitable for tea: clean dirt from the surface of an acrylic bath by rubbing with half a cut citrus, or quickly wash the microwave by placing a container of water and lemon slices in it for 8-10 minutes at maximum power. The softened dirt can simply be wiped off with a sponge.

There are special traps to combat moths. The sticky layer with which they are covered contains female pheromones that attract males. By sticking to the trap, they are eliminated from the reproduction process, which leads to a decrease in the moth population.

If your favorite things show the first signs of gestation in the form of untidy pellets, you can get rid of them using a special machine - a shaver. It quickly and effectively shaves off clumps of fabric fibers and returns things to their proper appearance.

The easiest way to remove scale and carbon deposits from the soleplate of the iron is with table salt. Pour a thick layer of salt onto the paper, heat the iron to maximum and run the iron over the salt bed several times, applying light pressure.

Reading time: 7 minutes.

Modern double-glazed windows provide a comfortable indoor microclimate. However, they also require periodic adjustments. Thus, it is possible to adjust the degree of pressing of the canvas to the frame depending on the season, which few people know about. It’s not difficult to do this with your own hands using a hex key, a screwdriver, or manually, depending on the type of locking devices.

Why regulate?

Different modes are needed for one simple reason - the change of seasons. Accordingly, there is a periodic drop or rise in temperature. The ability to close windows more tightly (or, conversely, less tightly) increases the access of fresh air into the room in the summer and reduces the outflow of heat outside in the winter.

If the window is constantly used in “winter” mode, this will lead to rapid wear of the seal due to the constantly high clamping pressure on it. If you leave the summer mode for the cold period, then there will be drafts and significant heat loss in the room. As a rule, during installation, windows are set in a neutral mode (spring/autumn), and when the season changes (that is, 2 times a year), it is recommended to make the appropriate adjustments.

Leak test

You need to prepare plastic windows for winter before the first frost. It is necessary to carry out a preventive inspection and check the tightness in the following ways:

Types of adjustment mechanisms

The degree of pressing of the sash to the frame is adjusted using locking mechanisms (trunnions) located on the side and upper ends of the sash. The appearance, quantity and location of these devices may vary depending on the manufacturer and price category of the double-glazed window.

The most common ones include:

• Round. Such trunnions have some kind of mark (dash, mark, dot, asterisk). If it is directed towards the room, then the window is set to “winter” mode, to the street – “summer”, upward – “neutral”.
• Oval. The vertical position is “summer”, the horizontal position is “winter”, the diagonal position is the standard “neutral”.
• Turnkey eccentrics. The shift into the room is “winter” mode, outward is “summer”, strictly in the middle is “neutral”.

It is not enough to install a PVC window block in the opening. It still needs to be adjusted correctly so that the doors close tightly and without problems. Also, periodic adjustments of the window must then be made independently or with the help of craftsmen in the spring and autumn in order to switch it to summer or winter operating mode. Moreover, this setting should be treated with utmost care. This is necessary not only to get rid of drafts, but also to increase the service life of the translucent structure.

Winter and summer mode adjustments

In winter, the plastic window should be closed as tightly as possible in order to reduce air exchange between the street and the room to a minimum. Nobody needs street cold in the house in winter. In summer, on the contrary, even when closed, it should provide some air circulation (micro-ventilation) so that the room does not become too stuffy due to the heat.

Seasonal adjustment of a home window by switching it to “summer” or “winter” mode is carried out using locking pins on the side of the opening sash. They can be fixed rectangular or roller (round with a notch on one side or oval).

Types of trunnions on plastic windows

Depending on the type, adjustment of this fitting is done by turning it manually, using pliers, a screwdriver or a hex wrench. Moreover, in some cases, before turning, the mechanism must be pulled towards you, and only then turned.

How to adjust window pressure

The window trunnion can be set in one of three positions:

1. “WINTER” – with maximum pressure.
2. “SUMMER” – with weak pressure.
3. Neutral (standard).

In the first case, on the round pin the risk is turned towards the street, and the oval one is set horizontally. In the second, the risk is installed inward, and the oval stands vertically. The third option - the dash looks up, the oval is fixed at an angle.

Instead of a movable pin on the sash, some manufacturers of window blocks install a non-adjustable locking element in the shape of a rectangle. In this case, adjusting the plastic window is only possible by adjusting the screw on the strike plate.

Window adjustment for winter and summer periods

The main point of seasonal adjustment of window sashes is the need to constantly transfer them from “summer” to “winter” and back. With strong “winter” pressure, the rubber seal is compressed, which is why it gradually begins to deteriorate. Often, owners of PVC windows are faced with the fact that after a few years this rubber band has to be changed. This happens precisely because the sash, according to the instructions of the window product manufacturer, is not switched to summer mode with a weakened pressure, but is left as is after winter.

How to adjust the hinges of a plastic window?

In addition to seasonal adjustments to the degree of pressure, plastic windows are also adjusted by tightening/loosening the screws in the hinges that secure the sashes to the frame. There are two of them - one below, the second above. They differ in design, so they are pressed differently.

Options for plastic window mechanisms

Hinges on plastic windows have to be adjusted due to:

• initially poor, illiterate settings of the window unit during installation;
• natural wear of the seal;
• inaccurate and rough closing of the valves;
• window structure shrinkage;
• wear of parts of the tilt and turn mechanism.

As a result of all this, the sash sags and does not close tightly or does not close at all. However, to return it to its place, you just need to tighten the hinges. Moreover, you can perform such a pull-up on your own. There is no need to call the experts from the company that installed the window. All you need to do is have a screwdriver and a hex key on hand. This is not repairing gasoline generators for the home or a submersible pump for dirty water; with window structures everything is much simpler.

Plastic window adjustment points

Upper

The top hinge is adjusted from the side using a hexagon when the sash is fully open. After turning the screw there clockwise, the window leaf moves away from the frame, and when tightened counter-clockwise, it is pressed so that there is less of a barrel on top.

For more precise adjustment, there is also another bolt on the upper tilt and turn mechanism. But to get to it, you will have to press the blocker (set it strictly vertically) and turn the handle to the top ventilation (also in a vertical position). As a result, the sash on top should pull away from the frame, hanging on the lower hinge and opening full access to the upper one.

Adjusting the top hinge

It is important here not to over-tighten the adjustment bolts. There should be a small empty space between the sash and the frame, where, when closing the window, a tilt and turn device made of steel will be placed.

Lower

The bottom hinge also has two adjustment screws. One of them is located on the side at the very bottom. He is responsible for horizontal adjustment - he presses the sash against the frame or pulls it away from it.

The second is located directly in the rotating mechanism itself. To get to it, you need to remove the plastic cap from the loop. This screw allows you to adjust the opening window leaf vertically (height). Turning it clockwise makes it go up, counter-clockwise means it goes down.

Bottom Hinge Adjustment

Manipulations when independently tightening the hinges on a plastic window should be done extremely carefully and without applying excessive force. Do not immediately tighten or unscrew the adjusting screw all the way. It is better to turn it a quarter turn first and close the sash to check to see how smoothly it has become in the frame. And only then, if necessary, can the bolt be tightened further.

How to adjust the handle

The handle on the PVC window block is actually not adjustable in any way and does not affect the degree of pressing of the sash. It is not involved in adjusting the window, but is only a mechanism for attracting the opening leaf to the frame, as well as transferring the latter to the position for micro-ventilation and opening from above.

However, often the handle becomes loose or begins to jam. To tighten or replace it, you just need to get to a couple of bolts. They are located under a plastic trim located on the profile at the base of this window fitting. This plug needs to be slightly pulled back and turned, the fasteners are immediately accessible.

If the handle is difficult to turn or is stuck, then the problem usually lies not in it, but in the hinges and the upper folding mechanism. These window elements are directly related to each other. It is possible for a wave to occur when the metal elements are rusty. Then the lever inside the profile will not allow the handle to turn. To get rid of this problem, you need to lubricate the hinges.

How to fix window problems

Problems with window units come in a variety of forms. In some cases, it will be enough to do the simplest adjustment of a plastic window with your own hands by tightening the adjustment screws, but in others you will have to change broken fittings. It’s much like with heating - most often you can achieve comfortable temperatures in the room by simply turning up the room thermostats for gas boilers. But in a number of situations it will be necessary to rebuild the existing heating system and replace some of its elements.

Ways to adjust the window system

Among the main problems are:

1. The sash touches the frame profile from below - height adjustment is required by tightening the end screw on the top hinge and the internal screw on the bottom.
2. The frame sash catches on the side - you need to adjust the bolt under the bottom hinge.
3. The valves do not fit tightly - this is regulated by trunnions.
4. If the locking bars are worn or broken, replace them and then re-adjust the entire window.
5. Handle jamming - first you should lubricate the tilt-and-turn unit on top and both hinges with oil, but if that doesn’t help, then replace it completely.
6. If the window handle is broken, just replace it.

The handle may also jam due to improper operation of the lock. There is no need to tighten or unscrew anything here. You only need to move the locking mechanism lever at the end of the sash to its original position. The jammed fittings should be freed.

Conclusion

It is not difficult to adjust the window unit yourself. There are now a lot of detailed video materials and instructions from manufacturers on this topic. However, seasonal adjustment of a plastic window in autumn/spring is not always recommended. When tightening the trunnions for the winter, the seal is excessively compressed and deteriorates. If it doesn’t blow in cold weather, then it’s better not to pull anything up. Let everything remain as it is. But if the sash is sagging and clinging to the frame, then it’s definitely worth taking a hex wrench or a screwdriver and tightening the screws in the hinges.

Adjusting the pressure of plastic windows

Situations often arise in which it is necessary to adjust the pressure of plastic sashes. Problems can manifest themselves in the form of the following points: leaky pressing of the sashes or sagging, repeated wedging, difficult closing, poor-quality installation and much more. The need for adjustment does not always depend on the duration of use of the windows; this may be due to the processes of shrinkage of the home. But you don't need to get too upset. To eliminate these troubles, you just need to carry out simple operations to adjust the pressure. And this simple process is very easy for anyone to learn.

Plastic window clamp

How to adjust the pressure of a plastic window:

Although plastic windows are distinguished by their comfort and practicality in handling, the fittings have a rather complex arrangement of mechanical parts that require careful operation and regular maintenance. When the above problem situations occur with windows, it is necessary to urgently adjust them to avoid further damage.

For these purposes, you will need a hex key with which adjustment is made. With this key you need to make turns in one of 3 directions:

left or right;

in relation to the frame down or up;

adjust the clamping density.

When carrying out these operations, you can eliminate existing minor defects after installing windows, which sometimes arise even after the work of experienced specialists.

For ease of adjustment, eccentrics with marks are located along the entire perimeter of the plastic windows, helping to find a reference point for pressing. In the case when the line is directed towards the street, this will indicate weak pressure, and in the opposite direction - very tight.

Adjusting the pressure of a plastic window

Along with a hex wrench, pliers, a wrench, or special plates that are located on the plane of the sashes are used to adjust the window panels. The choice of “work tool” is directly related to window designs. If the clamping mechanism is located on the hinge side, then the window adjustment operation can be carried out with a simple screwdriver.

The “tongue” will help in determining the degree of pressing of the window sashes - the more it is extended, the tighter the sashes fit.

To increase the clamping density and reduce the effort when closing windows, it will be necessary to rotate the hex key counterclockwise or in the opposite direction.

In cases where the problem is not resolved (even when implementing the methods listed), you will have to contact the experts to carry out serious repairs to the plastic window. They will replace the seal to solve this problem.

Adjusting the hinges of plastic windows:

Most plastic window designs do not include vents. To ensure ventilation of the premises, it will be enough to set the doors to the “ventilation mode”. However, with this mode, a rather large gap is formed between the sash and the frame, and in winter frosts there will be a rapid transition of warm air from the room to the street, and the room can become too cool. To prevent this phenomenon, it is advisable to come up with ways to reduce this gap.

There is also another extreme, when the wind simply “walks” in the apartments, let through by the sealant.

In these cases, adjusting the hinge pressure or, as a last resort, repairing them can help. In most cases, only one hinge is adjusted (the exception is in tilting windows, where both the upper and lower hinges are subject to these operations).

The regulation process begins with finding the location of the draft. For example, if it is located close to the bottom hinge, then there is a hexagon, and after removing the cap from it, carry out the actions described in the instructions (to raise the windows, turn the key clockwise, and to lower it, turn it in the opposite direction).

Adjusting plastic window hinges

To press the top hinge, you will need to set the window sash to the “ventilation” mode in advance (by turning the handle). These actions are necessary in order to gain access to the screw responsible for pressing the hinge. It should be remembered that the window will need to be supported, since in this mode it hangs only on one hinge.

Some companies equip their windows with locks, which during adjustment operations must be turned off before opening by pressing it before opening the window.

There are times when window handles become loose. This is also quite easy to fix yourself. To do this, you need to slightly lift the plastic plate located at its base and carefully rotate it in any direction by 90°C. After these steps, screws will appear. They should be tightened with a screwdriver until they stop.

But it also happens that the handle is very difficult to turn. To avoid such a situation, it will be enough to lubricate the fitting mechanisms, represented by hinges, clamping mechanisms and eccentrics. For lubrication, machine oil is used, an example of which is WD-40. It is advisable to carry out lubrication annually, and it is also recommended to check the fittings for various defects.

Although all operations for adjusting plastic windows are quite simple and can easily be done independently, however, to carry them out it is advisable to familiarize yourself with and comprehend all the proposed recommendations. If there is any doubt that you will not be able to solve problems, you should contact the services of specialists.

Instructions for self-adjustment of plastic windows

Korovin Sergey Dmitrievich

Master of Architecture, graduated from Samara State University of Architecture and Civil Engineering. 11 years of experience in design and construction.

Plastic windows have long established themselves as reliable and durable frames that maintain the temperature of the room and do not allow drafts to penetrate. Many people install plastic, but do not carry out maintenance and forget about the subtleties of use in the form of switching to seasonal mode and other necessary little things.

Correct adjustment of plastic windows and timely maintenance are the basis for a long service life, eliminating sudden expensive repairs.

Adjusting the sashes

Often, adjustment of window fittings is necessary when the quality of installation work is poor, when the structure is not aligned vertically and horizontally. It is also required in case of natural wear and tear, when the sashes begin to touch the frame and fittings. If the windows do not fit tightly, cold air begins to pass through and drafts appear. Instructions for self-adjustment of plastic windows will help you save a significant amount on the services of third-party specialists.

To work you will need simple tools:

Inspect the window to determine the installed fittings, since the adjustment will directly depend on this factor. In one case, the sash will need to be removed, in another, tightening the fastening screw will be sufficient.

Horizontal and vertical adjustment

On the horizontal side, the sash is subject to adjustment in the event of a bevel of the frame caused by shrinkage of the structure, incorrect opening of the window or loose fastenings of the fittings. To fix the problem, you need to insert a hex key into the upper window hinge, turning it clockwise until the sash moves a sufficient distance away.

Adjusting the top canopy

In this case, the lower part of the opposite element should drop noticeably. The lower hinge is adjusted from the outside. The shifts average 2 mm.

The window can be adjusted vertically using the hinge located at the bottom of the frame. The protective cap is removed from the loop and the rotational movements of the tuning mechanism begin. Moving the tool in a clockwise direction will raise the sash, moving it in the opposite direction will lower it.

Adjustment of plastic structures should occur smoothly so that the mechanisms move no more than 1 mm in one approach.

The sash stopped closing: problem solving

Adjustment of the pressure must be made when the window has difficulty moving from the open position to the closed position. Often the reason is the lock device, which does not allow the handle to be turned. The exact sequence of actions depends on the specific manufacturer. Some examples are equipped with a thin plate equipped with a spring on the inside, which must be pressed and the handle turned to close the window. Other copies are equipped with a tongue under the handle - when you press on it, the lock of the adjusted mechanism is removed.

In a situation where the window still does not want to close, minor repairs will be required. It is necessary to open the sash, find the element of the mechanism that serves as a hook for the tongue, unscrew and install a thin plate on the inside. The solution helps to shift the mechanism closer to the response element. As a result, the contact area will increase, allowing you to easily close the window.

Pressure density adjustment

Setting the pressure on a plastic window is quite simple if you follow a simple sequence of actions. Find in the area of ​​the handle, located at the side end, a system of eccentrics that serve as the main adjustment tool.

Winter and summer mode can be adjusted using trunnions

Their external design may be slightly different depending on the window manufacturer, but the principle of operation is the same, whatever their type.

Using a hex wrench or pliers, the desired degree of pressing of the sash is adjusted by rotating the eccentrics. In the summer, manufacturers recommend setting weak modes, switching to strong ones closer to winter. Read more about this in the article about converting windows to seasonal modes.

When it is necessary to adjust the pressure on the side of the window hinges, you need to refer to the adjusting screw located on the bottom of the hinges. For tilt-and-turn sashes, additional adjustments are made using the top hinge.

In order to successfully get to the adjustment bolt located on the scissors next to the top hinge, you need to open the window, press the locking tab and set the handle to the ventilation mode. When it is necessary to press the sash against the window frame, the bolt rotates clockwise. Rotating in the opposite direction will weaken the seal.

The method of adjusting window fittings depends on the manufacturing company, since there are varieties that are adjusted with screwdrivers located on the side of the handles. Others only fit hexagons. In order to increase the pressure, the bar is carefully shifted to the street side. If you look at the hinges, you will notice retractable clamping elements. A smaller extension will provide a loose fit, while a larger extension will press the sash tightly against the frame.

Cleaning the fittings from accumulated dust

Once every 5-7 years, windows need deep cleaning to remove accumulated dirt in hard-to-reach places. Without cleaning them in a timely manner, sooner or later you will have to repair them, since their functioning will be impaired. Repairs are quite labor-intensive in terms of the weight of the structure, so it is advisable to carry out the work with assistants.

Scheme for adjusting elements to keep them clean and tidy:

1. remove the sash from its hinges, removing the overhead frame elements;
2. remove the top axle;
3. remove the sash from the lower hinges;
4. carefully set aside.

Removal of elements must be done with an assistant

The surface of the sash is carefully inspected and the screws attached to it are unscrewed. The mechanism parts are washed well, preferably using specialized solutions that are easy to apply with a brush. After this, the structure is dried well in the fresh air or with cold air from a hairdryer. Lubricant is applied to each driving mechanism. The fittings are assembled in the reverse order and installed in their original place.

Before assembling the window, all fittings must be lubricated.

We repair window handles

Questions about adjusting window frames are quite often related to the operation of the handles, since from time to time they can break or lose functionality. It is important to remember that the handles of a plastic window require periodic attention, since more often than other parts they are subject to rapid wear: sometimes they require repairs or complete replacement.

Timely adjustment is the best solution to the problem of handles losing functionality. Thus, a fairly loose handle requires tightening the fasteners, which can be done in a matter of minutes, since this breakdown is one of the simplest types of repair work.

Find the decorative rectangular trim under the handle, lightly hook your fingers on both edges and turn 90°. There are a couple of bolts under the trim that need to be tightened with a Phillips screwdriver.

You should not use tools to lift the plate covering the bolts, since there is a possibility of damaging the surface of the profile and disrupting the shape of the plug element.

Another common problem is the handle sticking, which periodically does not turn to the required angle. In this case, you need to lubricate the fasteners with machine oil using a cotton swab. A special spray or silicone lubricant will also work.

The problem of the handle sticking can be solved by lubricating the fasteners with oil.

To replace, the handle is rotated 90° and the cover in the form of holding screws is removed. The unscrewed element can be easily replaced by installing the screws in the same sequence. Repair of plastic windows with complete replacement of fittings is inevitable if the handle is thoroughly jammed. Cases are extremely rare, but they do happen.

Do-it-yourself adjustment will not be difficult for owners, since the whole procedure is quite simple. It is only important to approach the setup with a degree of responsibility and strictly follow the instructions.

Do-it-yourself adjustment of 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 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"

General principles for 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.

Figure 1 - General principles for adjusting PVC windows
Figure 2 - General scheme for adjusting a plastic window Figure 3 - Various window adjustment options

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:

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 (Figure 4).

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 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.

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.

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 it is recommended to apply weak pressure, and in winter - strong pressure. 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 - Window pressure adjustment

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.

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

6. The sash is closed, but the window does not close - 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, 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 “Plastic window does not close - what to do?”

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.

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 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.
