The plastic window doesn't close well, how can I fix it? Necessary seasonal adjustment of plastic windows winter-summer. The handle sticks or does not reach the desired position

Metal-plastic windows have a number of advantages: they transmit light well, allow you to ventilate the room with varying intensity, provide reliable heat and sound insulation, are easy to maintain, and durable (on average, their service life is 15-20 years). It would seem that if you change the windows, you can forget about them. But that was not the case. In order for everything to work correctly, adjustments need to be made occasionally. plastic windows.

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 pressure 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;
problems with 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 then buy new parts or completely change the broken window structure

For those who have sliding windows and doors, if there are any problems with 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 shutters are 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 pressure on the sashes 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:

Open the window. Locate the adjustment screw at the end of the sash (usually it is located closer to the top).
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.
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:

Carefully remove the protective cap from the bottom hinge.
Rotate the adjusting screw in the desired direction (clockwise – the canopy rises, counter-clockwise – lowers), turning it half a turn with a hex key.
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. Step by step instructions is this:

Open the window flap.
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.
The pressure of the upper sash 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 them, 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 chosen 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 Isn't Just for Tea: Clean Up Surface Contaminants acrylic bathtub, rubbing with half a cut citrus, or quickly wash the microwave by placing a container with 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.

Over time, even initially perfectly installed plastic windows may require adjustment or maintenance. The reasons can be various - subsidence of the house, wear of fittings, poor quality of window frame material, etc. And nothing lasts forever, but with timely care you will greatly extend both the functionality of your windows and your nerves, enjoying the use of windows or plastic doors , and not a constant influx of negativity every time you use the window.

Usually, adjustments and minor repairs are carried out by specialists, but this is associated with a number of inconveniences - you have to wait for the technician to arrive, you spend not only your time, but also your money, paying for the work of a specialist. But, in most cases, you can adjust the window yourself and do not require any special skills, tools or abilities. It's quite simple.

The main signs when adjustment of a plastic window is required.

This also applies to plastic doors- both the signs and adjustment methods are completely identical.

When opening and closing, the sash clings to the frame or fittings.
The lower part of the sash is sagging and when opening it touches the frame.
When the window is opened, the upper part of the sash falls out and the window hangs on one lower mount.
The window or door does not close tightly, there is a noticeable draft, sound insulation is reduced
The handle became loose or, on the contrary, became very tight.
When the window is open, the handle jams and the window does not close.
The window opens with great effort.
Creaking of hinges and fittings mechanism.

If these signs are present immediately after installation or during the first week of operation, it is advisable to immediately contact the installers to eliminate the cause. If plastic windows are installed incorrectly, it is simply impossible to achieve high-quality functioning of a window of any brand and any cost only by adjustment. The window will need to be partially dismantled, leveled and re-attached. This can also happen if the window or door frame is poorly secured. In this case, as a rule, the defect does not appear immediately, but after a short time.

If the above symptoms appeared to you after 0.5-1 year of operation or more, then most likely this is our case and you will be able to independently adjust the plastic window or balcony door.

What tools are needed to adjust the window?

Basically, only a hexagon is used, which in everyday life is called a furniture key. This is a small L-shaped metal hexagonal rod, which for ease of use can be made in an S-shape of 4 mm. (In rare cases, a different size). Often comes complete with accessories. If you don’t have one, after measuring the size first, buy it at any hardware store - it costs a penny, it will always come in handy.

You may also need a Phillips screwdriver. Basically all the tools.

Plastic window design

Manufacturers and brands of windows, as well as the fittings used, may be different, but the typical design of a tilting window is the same. If the window is not folding, but simply turning, then the design is simplified and the upper mechanism of the folding window is not used. The rest is the same.

Exactly the same mechanism in plastic doors, for example, balconies.
Let us note once again that each hardware manufacturer has a number of options for the standard set. These could be functions:

Child protection;
- protection against pressing the sash;
- additional ventilation mode - micro slot winter (a small gap is formed around the perimeter between the frame and the sash when the handle is turned up 45 degrees);
- fixing the sashes in different positions;
- external handles, etc.

But the principle and method of adjustment are the same. Next, we will consider the points and places of adjustment.

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

The trunnions of the locking mechanism are responsible for pressing the entire sash. In some types of fittings, the clamp is adjusted by responders on the frame.

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

What and where to adjust in a plastic window for various symptoms

1. The sash is sagging, there is friction when opening or closing the window.

This can be eliminated either by lifting the sash upward, or by moving the bottom of the sash towards the sagging side, and the top towards the hinges. It is clear that before making adjustments, remove the decorative cap from the hinge using a flat-head screwdriver, simply pushing it up. We insert the hexagon into the hole from above and turn the stop screw (pictured on the left). When twisted (clockwise), the sash rises and falls when unscrewed.
To move the bottom of the sash, rotate the screw on the frame part of the hinge on the side (pictured on the left). If the key is rotated clockwise, the window sash is attracted to the hinge

Shifting and adjusting the top of the sash left and right is carried out by a screw located in the scissors, on the side of the top hinge. To get to it, you need to open the sash and rotate the screw to the desired position of the sash. Make adjustments smoothly. Turn it half a turn, check, then another half turn. Try to make adjustments in a comprehensive manner, using different screws according to the rules of school geometry.

2. The window or door does not close tightly.

The pressure density of the plastic window sash is adjusted by rotating the eccentrics located around the perimeter. To reduce the pressure of the window sash against the frame, you need to rotate the eccentric counterclockwise. To increase the pressure and reduce the gap (eliminate the gap), you need to turn the eccentric counterclockwise. Also, the clamping mechanism is located on hinges, its adjustment is carried out with the same hex key.
Adjustment must be made along the entire perimeter of the sash. In some brands of fittings, the clamping density is regulated by the mating part, which is located on the frame.
An extended tongue in the clamping mechanism means that the sash is firmly attached to the frame. On the hinges located on the left side of the window, to increase the pressure, turn the hexagon to the left or right - if the hinges are located on the right side.

It should be remembered that the stronger the pressure on the window, the faster the seal will wear out and the tighter the handle will turn when closing the window. Choose the optimal middle.

Below are various options adjusting a plastic window or door. You have already figured out what and where to turn.

3. The handle is loose or too difficult to turn.

In any case, you will need to get to the handle mount. It is attached to the window with screws, which are covered with a decorative plate. This plate must be rotated 90 degrees at the base. Next, either tighten the fastening if the handle is loose, or unscrew and lubricate it. By the way, it wouldn’t hurt to lubricate other rubbing mechanisms. WD-40, silicone grease or machine oil are quite suitable as a lubricant.

These simple steps on adjustment and prevention of mechanisms of plastic windows, as well as plastic doors done on time, will increase their service life for a long time, and you will experience nerves and financial waste. In fact, everything is simple and accessible to anyone, including a woman, if a man is not nearby.

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

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

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

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

General principles for adjusting the pressure of plastic windows

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

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

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

Types of pressure adjustment for PVC windows

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

Horizontal adjustment

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

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

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

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

Vertical adjustment

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

Necessary tools for adjusting the pressure of plastic window hinges

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

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

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

Technology for adjusting the pressure of plastic windows

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

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

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

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

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

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

Getting rid of drafts

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

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

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

Plastic windows have long ceased to be an indicator of luxury. Today, modern windows are considered a kind of indicator of the level of comfort at which your home remains protected not only from the cold, but also from noise. But for this you need to follow several rules in maintenance and care.

And if for quality and correct installation glass unit, you need to seek help from specialists, then all other periodic maintenance work can be carried out independently. And for this it is not necessary to have special knowledge and skills. It is enough just to understand the design features and be able to handle the tools.

Peculiarities

The design feature of plastic windows is the ability to adjust the mechanism during maintenance. And this procedure may be required for any window, regardless of the service life and quality of the fittings. It is important to periodically check the serviceability of the opening and closing mechanisms. And also, when the season changes, inspect the condition of the fittings - the durability and functionality of the windows depends on this, which will most likely save you from large-scale repairs in the future.

And being able to do all the work yourself is a useful skill. In fact, it is not as difficult as it might seem at first glance.

Plastic windows have many advantages:

optimal level of sound insulation - modern double-glazed windows protect living spaces from extraneous sounds from the street;
retains heat - the plastic frame retains up to 20% of the heat in the room;
excellent tightness - which allows you to protect the room from drafts, and there is no need to additionally insulate the frames before the onset of cold weather;
plastic does not deform under constant humidity and temperature changes;

fire safety - the plastic from which modern windows are made does not support combustion;
attractive appearance and many modifications - the customer has the opportunity to choose any size, color and style window frame;
ease of cleaning - to maintain cleanliness it is necessary to periodically wipe the surface of the frame with a damp cloth;
retains its original appearance for a long time - the surface does not fade in the sun, does not change color and does not require periodic painting;
multifunctionality - a modern plastic window also protects from insects and bright sunlight.

However, it is worth noting some disadvantages of plastic windows:

non-compliance with installation technology can shorten the service life of the window;
unlike natural wood, plastic is not able to maintain optimal levels of humidity and temperature in the room;
moving structural elements require proper maintenance;
over a long period of operation, replacement of fittings and insulation is required.

During operation, you may encounter many problems. The window can cling to fittings, let air through and cause drafts in the room. And most often, to fix the problem you only need to tighten the mounting screws and treat the fittings with oil. And in order to determine the cause of the malfunction, it is necessary to roughly understand the design features.

A plastic window consists of standard parts.

Plastic frame– inside which the reinforcing fortification is hidden. The entire structure must withstand enormous loads, so during the production process the frame undergoes quality tests. Self-tapping screws are used to securely fix the steel profile.
Doors– the sealed design of the doors also has a steel profile. All moving elements are made of reliable materials, which guarantees normal closing and opening of the window.

Double-glazed windows– depending on the requirements, manufacturers offer windows with one, two, three or more double-glazed windows: between the two glasses an air chamber is formed with a special gaseous substance, which is necessary to create excellent thermal characteristics.
Accessories- these are all the devices and parts located in the sash and frame, which are necessary for fixing the double-glazed windows, the handle and controlling the sash.
Sealant– necessary for hermetically closing the window. Insulation and sealing elements protect the room from moisture and cold air from the street. Over time, the quality of the seal may deteriorate due to natural wear and mechanical deformation.

Glazing beads- these are plastic parts that are necessary to hold the glass in the frame.
Impost– necessary to strengthen the structure if the window frame has more than one structural element. This element is fixed in the window opening and divides it into several parts. But recently, manufacturers have improved window frames and can offer customers large windows without additional fixing profiles.

Modern plastic windows differ in quality, number of double-glazed windows, strength, various modes and price. And each category requires proper care.

Modes

Modern manufacturers offer PVC windows with two modes of opening the sash: swinging and ventilation. The opening angle of the flap can also be adjusted by built-in limiters. A common problem with windows with several modes is the simultaneous opening of the sash and the opening of the micro-ventilation mode.

It can occur when the open sash is switched to ventilation mode by turning the handle up. In this case, the sash is fixed only on one lower hinge, and the upper part sags and falls under its own weight.

This problem needs to be solved in as soon as possible, otherwise the lower hinge may not withstand the load and break. To do this, you need to press on the top of the sash and try to press the window tightly against the frame. In this case, the handle must be turned up to the ventilation mode. Then, after the sash is completely closed in the frame, the handle is lowered to the swing mode. If necessary, you can independently adjust the lock on the sash. After this, the window closes.

But manufacturers of plastic windows also offer sliding structures. Such doors are best suited for installation on a balcony. The main advantage of sliding windows is that they save space; the windows are opened not by turning, but by moving them parallel to the frame. In this case, the window sill area can be used more efficiently.

Such windows do not require special care and will last for 10 years just like their classic counterparts. They retain heat in the room and prevent street noise from entering the apartment. Another advantage of these designs is the ability to move the mosquito net, like the frames themselves: the net can move parallel to the frame to the right and left.

And you can also additionally install special valves on the window for air flow or protection for children. In this case, you can be sure that the child will not be able to accidentally open the window.

Required Tools

Adjusting a plastic window at home is not a difficult task. In this case, it is important to have basic skills in using tools. Before work, you should prepare the necessary kit. The choice of tools largely depends on the internal mechanism of the window.

To adjust a plastic window you will need:

pliers or pliers;
hex wrench No. 4;
flat and figured Phillips screwdrivers;
a set of star keys;
scissors for seal;
spatula;
machine oil, silicone grease or WD-40 spray.

In some cases it is necessary to use different tools. For example, it is better to use pliers to turn oval-shaped eccentrics, and a hex wrench or screwdriver to turn adjusting screws with an internal slot. While only a Phillips screwdriver is used to replace the handle.

A spatula will only be needed if the straightening plate is faulty. But if the warranty is still valid, you should contact the manufacturer to have the problem resolved.

Although you can install the straightening plates yourself. The main thing is that the glass unit does not rest against the plate, otherwise the glass may not withstand the pressure and crack.

How to adjust it yourself?

Many people simply do not know or forget that plastic windows require periodic maintenance. Adjustment and adjustment of double-glazed windows may be necessary if a poor-quality installation was carried out. Just like natural wear and tear can make itself felt within several years even after a quality installation. And even experienced craftsman Questions may arise when adjusting the window.

You can read detailed instructions on how to fix the main problems you can fix yourself.

Friction is felt when opening or closing a window, or the sash touches the frame - in this case, the reason may be loose hinges. This problem can arise when the building shrinks or the fittings become loose. To eliminate the problem, it is necessary to adjust the upper and lower hinges horizontally. For this job you will need a hex wrench. Insert the key into the top window hinge and turn clockwise to adjust the height distance from the sash to the window frame. At the same time, the lower part of the opposite element will noticeably lower. To adjust the lower hinge, you will also need a hexagon, but the same work must be done from the outside. The shifts average 2 mm.

Draft and blowing windows– cold air enters the apartment through the frame insulation. During operation, the window may lose its seal due to wear of the rubber seal. Manufacturers provide a guarantee of about 15 years for high-quality seals. If you neglect to monitor the technical condition, the seal may wear out. To replace it, carefully remove the defective seal from the grooves and attach a new one.

The handle turns hard– the problem may be a malfunction of the mechanism or lack of lubrication. In this case, first you should treat the mechanism with machine oil. To do this, turn the handle at a right angle, unscrew the screws and remove the plastic decorative trim. Under the rectangular plate there are bolts that are tightened with a screwdriver. If the mechanism periodically jams or the handle is difficult to turn, lubricate all elements of the turning mechanism. If there are visible defects, or if after treating the fittings with lubricant the problem has not been resolved, replace the handle with a new one and check the technical condition once a year.

If the handle is stuck in ventilation mode– most often the reason lies in the jamming of the mechanism called “scissors” in the upper corner. The problem can be dealt with only after removing the sash from its hinges. To do this, carefully remove the decorative plugs and unscrew the screws. After this, inspect the ventilation fixing mechanism, find and try to adjust the elements that have flown off. Replace all the elements and check the functionality of the “scissors”. They should be adjacent to the top loop. After this, install the sash in place in the window opening.
Tilt&Turn Problems are eliminated quite simply. If the window is opened in two modes at once, you need to quickly return the sash to its place with a slight pressure and lower the handle down to close the mode.

Most problems can usually be resolved by adjusting the top and bottom hinges of the window.. To check the pressure of the sash to the frame, you can hold a lit candle to the window: if the fire goes out, it means that the sash needs to be adjusted. In this case, it is necessary to check the trunnions - these are small round-shaped parts that are located on the sash and regulate the pressure. To make the contact between the sash and frame more dense, it is necessary to turn the mechanisms clockwise, and to loosen the pressure, turn them counterclockwise. This adjustment should be carried out twice a year when the season changes. In winter, the window must be tightly closed so that cold street air does not enter the apartment. And in the summer heat, on the contrary, the pressure should be minimal so that the room can receive fresh air even with the window closed.

During the first year of window operation, adjustments should be minimal. It is important to remember that with loose pressure the window will last longer than with maximum tightness.

What to do if it doesn't close?

Quite often a problem arises when the sash stops closing. And this is not surprising, especially if the window was installed 5-6 years ago. In such cases it is necessary to carry out minor repairs. And fortunately, you can do this job yourself. But first you need to understand the cause of the malfunction.

A window may stop closing for several reasons:

manufacturing design defect;
poor quality fittings;
neglect of installation rules during installation;
sash misalignment;

The seal needs to be replaced;
malfunction of the opening and closing mechanism;
debris, dirt or dust.

If you cannot close the sash tightly, you should first make sure that there are no elements obstructing this. Another problem may be sash misalignment. In this case, the window will cling to the corner of the frame, and as a result of the distortion, a gap will appear. If one of the corners of the sash is sagging, it is necessary to adjust the bolts on the hinges. To do this, you need to adjust the angle of the sash vertically and horizontally.

And if you cannot turn the handle, then perhaps the problem lies in the blocker located on the side at the bottom of the sash. Adjust the position of the lock yourself and try turning the handle. After these manipulations, the problem should be resolved.

Replacement of accessories

On the end part of the sash there is large number various elements. The fittings play almost the main role in the quality of the window and are responsible for trouble-free operation throughout the entire service life. And the service life of the window depends on the quality of the fittings.

Window fittings are divided into three types.

Budget– often used by developers in new buildings. Such accessories are offered by domestic manufacturers, and they are usually limited in functionality. For example, windows with budget fittings do not switch to different seasonal modes and do not have the function of opening for micro-ventilation.

Standard– produced by both domestic and foreign companies.
Specialized– used by various manufacturers for windows installed in crowded places: airports, shopping centers, administrative buildings.

All types of fittings differ from each other in quality, design complexity and reliability. When working with replacing and adjusting fittings, you must be careful. Any small breakdown can cost the owner of the apartment dearly in the future.

The following tips and recommendations will help you fix plastic window problems without the help of specialists. But the main thing is to carry out all work without pressure and effort, otherwise there is a possibility of larger breakdowns. Find out what else you need to know to adjust a plastic window yourself.

In some cases, it may be necessary to adjust the window frame vertically. To do this, you need to remove the decorative plastic cap from the bottom hinge and use a hexagon to adjust the position of the frame. Circular movements clockwise will raise the sash, and counterclockwise will lower it.

Once every 5 years, it is necessary to clean the fittings in hard-to-reach places from accumulated dust and dirt. This process cannot be called labor-intensive, but doing this work will be much easier with two people. To do this, you will need to remove the sash from both hinges and remove the overhead elements. All parts must be cleaned and the moving elements lubricated with oil. After complete drying, the fittings are installed in their places, and the structure is assembled in the same sequence.
It is not recommended to wash windows using abrasive cleaners and solutions. To clean the surface, it is best to use a soft cloth and a special product for plastic windows.

Monitor the quality of the rubber seal - it needs to be replaced periodically. It should not have cracks or cuts. To make the seal last longer, periodically inspect the window and lubricate the rubber with silicone grease. Without proper care, the seal will become unusable after 5-6 years of operation.
If the window is used for a long time, the seal may need to be replaced. This need is not always associated with poor quality rubber or inadequate care; there is also such a thing as physical wear and tear. Perhaps even an ordinary person can cope with replacing the seal. You need to purchase a new rubber seal from a hardware store and carefully remove the old one from the surface of the sash. It is better to start all work from the lower or upper corner. After this, the surface and any open grooves are thoroughly cleaned. Check in advance that the amount of new rubber is exactly enough for the entire window; the seal cannot be stretched.

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

How does the double-glazed window sash mechanism work?

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

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

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

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

When do you need to adjust the window sash?

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

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

Thirdly, manual adjustment of the gaps will be needed when the seasons change. In winter, everyone wants perfect tightness of the joints (so as not to blow), and in the summer, no one will refuse a slight draft.

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

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

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

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

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

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

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

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

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

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

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

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

Adjustment does not help - change the seals

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

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

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

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

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

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

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

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

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

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