Not so long ago, in our country, old, ubiquitous and boring wooden windows began to be replaced with cheaper and more reliable plastic ones. Their design is impeccable. And the results that such windows have been showing for a long time simply exceeded all the expectations of the domestic user. But time passed and, like any movable structure, these windows began to show their disadvantages. Disadvantages, the elimination of which is not difficult. And you can do this yourself, since adjusting such windows does not require much physical effort and does not require any qualifications. But, if you are experiencing difficulties, then at any time you can consult with our employees of the VIPlast company, which is engaged in the installation and installation of PVC windows http://viplast.ru/produkciya-i-uslugi/montazh/. How to adjust plastic windows yourself? This is the main topic of our article. Today we will talk about the most common problems that owners often encounter over time.

Sagging and friction

If a window is used for a long time without proper care, what often happens is that the window does not fit into the frame so easily and clearly. When closing, unnecessary friction occurs, and perhaps the window does not close at all. What did the manufacturer leave us to resolve such defects? In the places where the window is attached to the frame, after removing the protective decorative cap, we find two holes that have a regulatory function. Most windows are made with a number four hexagon. With its help we will rebuild our window. And so, by operating the hexagon on the top and bottom hinge, we can change both the height of the window and the angle at which it hangs.

If our hexagon enters vertically, then now we adjust the height, and if horizontally, we change the angle. This simplest formulation of your next actions will give you awareness of your actions. We will not talk about how long to scroll something, since each situation is individual and we do not have the right to give a clear answer.

In addition to all kinds of friction, sagging, etc., users can independently carry out a number of works related to increasing the functionality of windows. Not many people know that plastic windows have two operating modes: winter and summer. For experts, this question is one of the frequently asked questions - how to adjust plastic windows in winter-summer modes? We'll talk about this later.

Do-it-yourself adjustment of plastic windows winter-summer

The main factor for adjusting windows in winter and summer is strengthening or weakening the level of pressure on the window sash. To do this, the manufacturer usually provides us with about three so-called trunnions - visually it looks like a protruding bolt head on the side of the window - eccentrics that regulate the pressure of the window at the end. In more expensive and high-quality fittings you can find trunnions that can be adjusted either with a hexagon or with an ordinary screwdriver; in some modifications there are even models where this can be done manually by pulling the head towards you and turning it. The manufacturer often releases windows in the middle position called “autumn-spring” so that its products can satisfy even those who have never heard of the fact that windows need to be adjusted for the season. Adjusting plastic windows yourself for the winter follows the following instructions: turn the trunnions to the left (counterclockwise) a few millimeters until they stop. In order to weaken the degree of pressing of the sash, we need to turn it in the opposite direction, but there will be no stop here.

The bolt must have an identification mark - a slot, an arrow, etc. How much it costs to turn these pins again depends on how worn your window is, and accordingly, it is a purely individual thing. It is not worth tightening it completely during the winter period, as the sealing material may become deformed. The level of pressure must be identical everywhere, otherwise you risk damaging the window structure.

If you are performing such an operation for the first time, then the amplitude should be minimal, since the window should serve us as long as possible with a minimum number of repairs. Remember: the more you turn the trunnions, the more stress you put on the rubber seals, which wear out over time and need to be replaced. Another tip for you so that your windows last as long as possible and the number of blows is reduced to zero - silicone. Ordinary automotive silicone, which is preferably used to lubricate silicone inserts around the window - they limit the passage of air through the window.

The window does not close due to the fixed handle]

Another rarer, but still relevant problem is a glitch in the handle blocker, due to which we end up with a window with a fixed handle, due to which it simply does not close. The solution to this problem is very simple manipulations. If we see the inscription “AUBI” on the lock, then you need to put the shutter in a vertical position and, holding the metal plate with the spring, turn the handle in the desired direction. If the inscription is different, then we need to adjust the tongue itself under the handle, pressing on it and turning it to the position we need.

Today we have looked at the most common problems that occur among ordinary users of plastic windows. We hope that the article was useful to you!

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 about 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.

    Arm adjustment

    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 the same as 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.

  • High-quality installation of metal-plastic windows and proper care will help you not to think about replacing or repairing them for a long time, even up to 50 years. The only thing that may be required from time to time or when winter and summer change is the adjustment of plastic windows and doors. For this purpose, you can invite a specialist, or you can do it yourself.

    Metal-plastic windows are very popular among consumers because they are comfortable both in winter and hot summer

    To understand when and what needs to be adjusted in your plastic windows or they need to be repaired, pay attention to the following:

    • whether the fittings function correctly, whether the opening and closing process occurs well;
    • do the doors touch the frame?
    • is there a draft that may occur after the seal has lost its quality characteristics or has worn out;
    • whether the handles function well, whether they are loose or not too tight.

    If you notice such moments during the operation of your plastic windows, then most likely they will have to be adjusted. The same applies to plastic doors. They also need to be monitored and their work adjusted. When winter and summer change, compression of the metal fittings and hinges may occur, and the operation of the mechanisms undergoes some changes. You can adjust this with the participation of a specialist or with your own hands.

    Sometimes problems can arise even immediately after installation if it was done incorrectly or completely poorly. Other problems may arise when using plastic windows and doors after some time.

    If you immediately notice shortcomings in the operation of the fittings of plastic double-glazed windows, then it is better to take advantage of the company’s guarantee and call a specialist. After all, repairs or adjustments due to poor-quality installation or defects in the fittings themselves cannot be done independently.

    All parts of the plastic window structure must be in good condition, even in winter or summer.

    The window pressure needs adjustment if:

    • the sashes are not pressed very tightly;
    • often requires wedging;
    • the closing process is quite labor-intensive;
    • The doors sag somewhat.

    What you may need for work:

    • hex wrench;
    • two types of screwdrivers;
    • machine oil or WD-40 aerosol;
    • pliers.

    Adjusting the sashes relative to the frame

    When you begin to notice that the plastic windows no longer fit tightly with the sashes to the frame and it is difficult to close the window, then do not rush to call a specialist, but try to fix the problem with a hex key. It must be turned in one of the directions: up-down, left-right.

    You can adjust the fittings of PVC windows yourself, either in summer or in winter.

    Sometimes it is necessary to adjust plastic windows or doors when shrinking a house. You can notice changes by the location of the eccentrics. These are special fittings that are located around the perimeter of the structure. When the handles are turned, these elements begin to move, moving beyond special platforms. There are marks on them, and if they are directed indoors, then the pressure is probably weak. If the eccentric mark is directed outward, towards the street, then the pressure is strong.

    In the case where the clamping mechanism is located next to the hinges, you can make adjustments using a hex wrench or just a screwdriver. This will depend on the type of fittings that are installed on the structure. By rotating the tool counterclockwise, you will reduce the tension on the flaps.

    Sometimes the problem does not need adjustment, but is eliminated after changing the seal.

    Debugging loops

    Most often, ventilation of rooms in summer and even in winter occurs by placing the sash in a certain position, since the presence of vents in plastic structures is not always provided for.

    If you have been set the size of the gap for ventilation in winter or summer, but it does not suit you, then you can change it yourself.

    The adjustment should begin with the loop next to which the ventilation area is located. Using a hex key, adjust the position, then open for ventilation and in this position adjust the second hinge.

    Debugging handles

    Many plastic structures already have a special lock that prevents the sash from opening. But if the handle is not fixed well enough, this may interfere with the quality of the structure. To fix the handle, you should slightly lift the plastic plate around it and turn it to the side. Under it you will see bolts with which you can fix the handle by simply tightening them.

    If the handle does not move very well and cracks, then ordinary machine oil will help you, and lubricate the mechanism with it.

    Even if everything works quite well, it is advisable to check the mechanism yourself at least once a year - either in winter or summer. During adjustment, you will need to lubricate all moving and sliding parts with oil.

    If the handle of a metal-plastic window has become loose, it should be secured

    Now you can easily start adjusting plastic windows and doors for winter and summer with your own hands.

    Seasonal debugging

    Depending on the time of year, the pressure is adjusted. If in winter it should be made tighter in order to retain heat in the room and save fuel, then in summer it is necessary to loosen it somewhat so that air can pass even into a closed room, and the fittings do not have severe wear. After all, it is more difficult to repair hinges and other mechanisms than to prevent it.

    The operation of PVC windows implies their adjustment to winter or summer modes

    A simple and effective way to understand how correctly the valves are pressed is to insert a sheet of paper between them and pull. If it comes out easily, then the pressure is very weak. If it breaks, then everything is done correctly.

    Procedure

    The appearance of gaps between the sashes may occur due to wear of the sealing rubber. But most often the reason is simpler - seasonal fluctuations in thermal conditions, when sharp temperature changes occur from winter to summer. To correct this problem, you should adjust the plastic windows and doors for winter and summer. You can do this yourself, without even resorting to the help of specialists. It is only necessary to debug the window fittings so that everything works clearly and efficiently.

    1. We find eccentrics on the sashes. These are metal cylinders that are located in plugs. There are special grooves in the frame where the hooks should go in order to press the sashes. Their position can be adjusted using eccentrics.
    2. To adjust, turn the eccentric using pliers or a screwdriver.
    3. If you cannot adjust them, then the position can be changed using hooks. This can be done easily with a hex wrench.
    4. When the clamp is set, we move on to debugging the canopies. We remove the plastic plug; there are bolts under it. We turn them with a hexagon in the direction you need: clockwise the pressure will be strengthened, and vice versa. It is better to adjust with the window closed.
    5. The upper part has a different mechanism, and it is better to adjust it in the open window position. The mechanism has a special lock, which must be pressed. After pressing, you must turn the handle to the ventilation position. When the sash is removed, you can get to the element you need - the head. Use it to change the pressure.

    Adjusting PVC windows and doors does not require special skills and can be done at any time of the year, both in summer and winter or in the off-season

    Finally, you need to lubricate the sliding and rotating elements of the mechanism with oil. This will serve as good protection against wear and will extend the service life for a long time.

    Debugging and repair of plastic doors

    Adjusting the pressure of plastic door panels and hinges occurs in almost the same way as window panels. But the process will be somewhat more scrupulous, since you need to compare the pressing force along the entire perimeter of the canvas.

    You can do the following: in the closed position, draw along the perimeter of the canvas with a pencil and compare the dimensions of the drawn line. It should approximately be in the range of 7-9 mm and not vary with a difference of more than 1 mm. Otherwise, metal-plastic doors should be adjusted in the same way as window mechanisms.

    If, when installed in the middle of the door leaf, the pressure against the wall was stronger, then the shape of your door will look like a barrel. This means that the adjustment will not give the desired result. The same situation will happen with the door if the pressure against the walls was stronger from above or below.

    The longevity of PVC windows and doors depends on proper installation and further maintenance both in winter and summer

    It is sometimes possible to solve this problem by replacing the sealing rubber with another one. But still, if you find such flaws in the installation, then do not rush to make the adjustment yourself, but contact those who installed the doors for you.

    You have modern plastic windows installed in your apartment or country house, which have served flawlessly for a long time. And suddenly minor malfunctions began to appear: they noticed that the sash began to not close completely, and a draft and extraneous noise appeared in the room; The handle became blocked and would not turn. All these minor troubles can be easily eliminated. The main thing is to understand the scheme and technique for adjusting PVC windows, individual parts and fittings, and the window will function correctly again. Before troubleshooting a plastic window, you need to study the step-by-step work, as well as prepare the required set of tools, without which the task will not be completed. Just prepare your windows for the coming winter.

    Tools for adjusting PVC windows

    To set up the window mechanism, you need to acquire the following tools:

    • hex wrench;
    • a set of screwdriver bits (star-type);
    • a Phillips screwdriver and a regular flathead screwdriver;
    • pliers.

    It is better to use car oil or a special aerosol as a lubricant.

    Find out what types of window fittings are available for plastic windows.

    Many window adjustments are carried out using a hexagon. A set of screwdriver bits can be useful if, in the production of the window frame, mechanisms were used that had bolts with a specific tip for a star-type bit.

    Basic areas for adjusting plastic windows for the winter period

    Compared to a sliding window mechanism, adjusting swing sashes in plastic windows is a more labor-intensive process. You need to know the main adjustment points, of which there are five. By adjusting them, you can raise or lower the sash, adjust it horizontally to the left or right, or adjust one of the corners located at the bottom of the sash horizontally. There are also two more adjustment sections, the adjustment of which allows you to reduce or increase the density of pressing the sash to the frame.

    Adjustment of window and balcony handles

    It happens that the window or balcony handle has become loose, so the sash does not close tightly. To eliminate this malfunction, it is necessary to tighten the fastening mechanism of the handle itself. To do this, remove the rectangular trim under the handle. She calmly rises and turns to the side 90˚. Underneath there are bolts that need to be tightened with a Phillips screwdriver. You can remove the cover easily, without much effort or picking with a screwdriver., which can only damage the profile and harm the edges of the overlay.

    How to Fix a Sticky Rotary Knob

    This malfunction is more significant, having several reasons:

    1. The mechanism may need cleaning and lubrication.
    2. If the handle does not turn completely to the position, or does turn, but with great difficulty, you may just need to slightly loosen the pressure on the sash itself.

    Adjusting the handle when the pressure is poor.

    We talk about which fittings for plastic windows are better.

    Two options to solve the problem:

    1. To clean and lubricate the entire mechanism, it is necessary to dismantle the handle. Cleaning can be done with a vacuum cleaner or a special brush. After cleaning, it is necessary to lubricate the mechanism.
    2. To reduce the pressing action, the eccentrics, which are located at the ends of the sashes on the side where the handles are located, are subject to adjustment. In addition, it is necessary to adjust the bolts located on the hinges on the opposite side.

    Adjusting the handle that is blocked

    If the window handle is blocked, it makes no sense to replace it with a new one. In this case, you don’t even have to dismantle it completely. The occurrence of a malfunction is due to improper operation of the locking mechanism. At the same time, it does not allow the sash to change its state when it is open. To do this, you need to turn the locking lever to allow the handle to move freely.

    There are two ways to resolve this problem depending on the type of design of the window mechanism and fittings. In one embodiment, the locking lever can be in the form of a tongue located at an angle to the seal and screwed to the end of the sash when the window is open. In another embodiment, the lever can be in the form of a clamp that fits onto the seal and serves as a gasket.

    The window handle is broken

    If the handle breaks, the window cannot close. This type of repair can be done independently. To do this, you need to purchase a new handle either at a hardware store, or order it from the organization from which you ordered the plastic windows. Then proceed directly to the replacement work.

    To do this, it is necessary to dismantle the decorative trim that covers the attachment of the handle to the frame. It rotates freely in any direction. Then you need to unscrew the bolts that hold the old handle. The new handle is screwed onto the same bolts.

    Quite often, adults install PVC windows that have handles with a safety lock. This is due to the need to protect children from opening windows on their own. This mechanism prevents the window from opening.

    You will find detailed information about glass railings for stairs.

    If the fuse fails, you must turn the handle 90˚ along with the plug. Then two bolts are unscrewed. After which the old handle is removed from the sash (by gradually loosening it). A new one is placed in place of the old one, in the same position at the time of its removal, and bolted.

    Adjustment of PVC windows “winter-summer”

    Window adjustment for winter provides a high level of pressure, and for summer - a low level.

    Some adjustment rules:

    1. If there is a need to adjust the level of pressure of the sash to the frame from the hinge side, then for this you need to use the adjusting screw, which is located on the lower hinge.
    2. If the sash has a tilt-and-turn mechanism, then additional adjustment of the sash pressure on the side of the top hinge should be made.
    3. To access the adjusting bolt, which is located in the upper hinge area, you must first open the sash and then turn the handle to the ventilation position. Before doing this, press the locking lever.
    4. If you turn the blocker to the right, it is pressed against the frame; in the opposite direction, the pressure weakens.

    Adjustment of some types of fittings occurs using special parts located on the frame on the handle side. Their position can be adjusted using a hex wrench. For more significant pressure, it is moved closer to the outside. If there are clamping mechanisms on the frame on the hinge side, they can also be adjusted with a hex key. At the same time, if the tongue is pulled out more, the sash will have greater pressure against the frame.

    Adjustment of the clamping mechanism: due to cracks or according to the season

    The clamping device is presented in the form of a rubber seal, which can also fail over time. The reason for this is: shrinkage and loss of elasticity of the elastic band. When installing a new window, the sash fits tightly against the seal, and when the level of pressing force decreases, the seal is broken, which becomes insufficient for a tight fit.

    The manufacturer of window fittings has foreseen this situation, so the PVC window has a mechanism that allows you to change the clamping pressure when closing the sash. The pressure can be increased or decreased depending on needs or the season.

    In practice, the following situation arises when, in the summer, the rubber seal tends to expand, since it has the highest level of elasticity. In winter, the opposite situation occurs; the elastic band begins to shrink at low temperatures. That is why, in winter, it is necessary to strengthen the pressure so that the cold wind does not blow through the sealing joint.

    Read about the types of seals for metal doors.

    If you forget to adjust the winter version of pressing plastic windows for higher summer temperatures, the gasket will be deformed by the window sash. This may cause the sash to break. To avoid this situation, it is necessary to adjust the pressure before each season from winter to summer and vice versa.

    Clamping mechanism adjustment diagram

    To adjust the sash pressing mechanism, there are eccentrics for this purpose. These are special mechanisms - trunnions, which allow the sash to be firmly fixed when closed. The pressure adjustment is carried out using these pins.

    As the clamping force increases, the trunnions must be turned to the right. It should be remembered that with full rotation the eccentric returns to its original place. When the pressure decreases, the trunnions turn to the left. The above diagram is applicable only for those doors that open from left to right. When opening in a different direction, it is necessary to rotate the trunnions to the right to reduce the pressure, and to the left to increase it.

    What a magnetic seal for metal doors is is indicated.

    Manufacturers offer several options for adjusting these mechanisms. There are three such methods:

    1. The trunnion is rotated using a flat-head screwdriver. To do this, it is inserted into a groove located on the eccentric.
    2. The pin is clamped with pliers and pulled towards itself, then rotated.
    3. The pin is clamped with pliers and rotated in the required direction without being pulled in its direction.

    When using pliers to grip the trunnions, do not use too much force to turn the eccentrics. Initially, you need to make sure which option will be used to adjust the clamping mechanism. Otherwise it may be damaged.

    Don’t be afraid of this problem; the main thing is to start adjusting the window sashes in time.

    In practice, there are three common ways to adjust the position of a window sash:

    1. When the window sash begins to cling to the lower part of the frame along the edge of the handle with its lower section. To correct this problem, you need to move the sash upward and move its upper section in the direction of the support.
    2. When the sash touches the middle support of the frame. To do this, you need to move it towards the awnings. When the contact area is located closer to the top or bottom, it is necessary to move the sash closer to the corresponding support.
    3. When the sash touches the top opening of the frame. To do this, the lower part of the sash moves towards the support. If this adjustment is insufficient, the entire sash moves down.

    All adjustments are carried out using a hex wrench. To move the sash to the upper or lower part, you need to rotate the adjusting bolt, which is located in the lower support. To get to it, you need to remove the decorative plastic panel from the frame. At the top edge of this section there is a hole that you need to get into with a key. The sash is raised when the adjusting screw rotates to the right, lowered when it is turned to the left.

    It is possible that you will be interested.

    Below on the same support there is another adjusting screw. Access to it is possible from both sides of the sash. When this screw rotates, the sash moves closer or further away from the support. The adjustment is carried out as follows: the key is turned half a turn and the presence of a gap between the frame and the sash is checked. If the bolt is not turned sufficiently, it should be slowly continued to be turned until the contact is eliminated.

    Adjustment of the upper section (“scissors”) is carried out in a similar way. To get to the bolt with which the sash moves to the sides, you need to open the window wide. In this position of the tilt and turn mechanism, the hole for the adjustment key will be visible.

    You can see an example of summer-winter window adjustment in the video:

    All the described schemes for adjusting plastic windows do not present much difficulty in getting rid of faults with your own hands.

    The most common type of glazing today is plastic windows. Their popularity is well-deserved due to their high quality, durability, and the highest thermal insulation and sealing properties. Also, such windows have quite a wide functionality, since their system uses advanced modern fittings, which are quite complex and consist of many mechanisms.

    Since such a system is complex, it can fail or simply need to be adapted to different weather conditions to increase quality. This whole process is called adjustment, which is what we will talk about today.

    How to adjust correctly

    In order for plastic windows to retain heat better and prevent cold air flows from entering the room, they should be adjusted. This is done before the onset of significant cold weather, when the temperature is around plus five to ten degrees Celsius.

    Basically, they increase the pressing pressure of the window sash to the frame, thereby more strongly compressing the seal, which retains heat and protects against blowing and drafts.

    Mistakes when adjusting windows for winter and summer

    The most common mistake is to increase the clamping force too much. Thus, the quality of sealing of double-glazed windows will, of course, be as high as possible, but the seal will very quickly fail and will need to be replaced. Also, if the pressure is too high, the fittings will wear out and lose their rigidity.

    Too much clamping pressure also has a bad effect on completely new windows. The seal there has not yet had time to adapt to operating conditions and sudden pressure on it can completely ruin the material. Once loosened, the new seal will not return to its original shape.

    The next common mistake when adjusting plastic windows for winter and summer is uneven pressure. After strengthening, it is necessary to check the entire perimeter of the window so that it fits evenly; if this is not done, there is a risk that the denser side will pull away from the opposite side and blowing will occur there.

    Very often, after the cold weather has passed, when winter is over, everyone forgets to loosen the windows, which is absolutely forbidden to do. Since with the onset of warmth, plastic and rubber begin to warm up and expand accordingly.

    Thus, the pressure increases significantly, which can cause the window to become unusable if left in this condition for too long. Be sure to loosen the glass several times to allow air to circulate.

    Stages of work

    Adjusting plastic windows with your own hands is quite simple; for this you do not need special knowledge, tools or special skill in this matter. Anyone can carry out all measures to adapt and configure PVC windows, without much difficulty.

    The most common faults that are adjusted are sagging sash, which can cause it to get stuck or rub against the window frame. The appearance of a draft or deterioration of the tightness of the structure is associated with a change in the clamping pressure, which needs to be strengthened or weakened depending on the nature of the malfunction.

    Hardware fasteners can become loose and loose; this should also be promptly corrected to avoid their deformation and increase the quality of the window. Now let's look at how to fix each of the problems.

    Eliminating sash sagging

    This phenomenon manifests itself when one or more hinges holding the entire sash begin to weaken and give some vector deviation from the norm. Subsequently, the sash may get stuck at its lower corner, and when interacting with it, it touches the bottom, top or middle of the frame. Thus, the structure deteriorates very quickly and loses its properties.

    To adjust plastic windows, it is necessary to remove the protective caps from the hinge we need and tighten the largest bolt, which is responsible for attracting the window sash. If friction occurs from above, you need to loosen the upper loop and tighten the lower one. When a double-glazed window sags too much, it must be slightly lifted while tightening.

    If it is necessary to move the window door to one side, you should adjust the screws that are on the hinges in a vertical position. Depending on which direction the revolutions are made, the sash will move to the left or right.

    Eliminating blowing

    To eliminate drafts and various blows, it is necessary to adjust the clamping force of the plastic window sash. This is done very simply by acting on three trunnions, which are located on the end of the window.

    They are adjusted using a hexagon by turning them around. To adjust, make from two to six revolutions; as a rule, this amount is quite enough to create comfortable conditions.

    You can check whether this action is necessary using matches. Light one and carry it around the perimeter of the window, watching the flame. To check the uniformity of the pressure, you should use a piece of paper that is clamped between the sash and the frame while closing. This procedure is repeated along the entire perimeter of the PVC double-glazed window.

    Loose fittings

    If any elements of the fittings have lost the rigidity of their fastening, they should be tightened. Since such looseness is fraught with rapid failure of a separate section or the entire system at once. As a rule, all fittings are secured with bolts, which over time may lose their original rigidity.

    This problem can be solved very simply by tightening the bolts more tightly. Experts advise carrying out such a twist once a year to eliminate minor faults and prevent the system.
