PVC window modes. Summer and winter modes of plastic windows - step-by-step instructions. Types of adjustment mechanisms

The best indicator The quality of manufacturing a plastic window and its installation is affected by frosty weather. Perhaps this is why some prefer to install these structures in winter time. If your window was installed in the summer, and in winter you notice that it is blowing, then you should understand the reasons for this phenomenon. To do this, you can contact the company where the product was ordered and its installation was carried out, or you can insulate the plastic windows yourself.

Usually, quality product in principle should not create any problems. On the contrary, its purpose is to solve them. However, in reality everything turns out differently. However, do not rush to blame installers or manufacturers for everything - blowing from the sashes can be caused by the fact that the fittings were initially set to summer mode. In this case do-it-yourself repair plastic windows (or rather, setting them up) is quite simple.

I would immediately like to note the fact that in some designs the fittings do not allow changing the modes of plastic windows in accordance with the time of year. In order to find out whether your design supports changing modes, it is enough to study the system of trunnions that are responsible for this event. If the trunnion has a recess for a hex key or it is oval-shaped, then such fittings are initially designed to be able to adjust the mode. In this article we will talk about how to set winter mode on plastic windows, considering all the intricacies of this process.

Winter mode of plastic windows - setting up fittings

The optimal time to adjust the fittings is late autumn (you can also catch this moment if you feel cold air blowing from under the window sash). In this situation, if you do not experience discomfort while indoors in winter, then it is highly not recommended to switch plastic windows to winter-summer mode. This is due to the fact that with such manipulations the rubber seal wears out much faster. If you feel the need to calibrate the fittings for winter mode, then try to be as attentive to this process as possible. Due to incorrect settings, you can damage the fittings themselves.

Considering the fact that you can set up the winter mode of plastic windows yourself, we offer you a complete guide to action. This way you can save on the services of specialists.

So, let's look at the sequence of your actions:

1. Raise the hardware roller.
2. Use a hex wrench to adjust the amount of pressure (the direction of rotation of the trunnion can be determined by trial and error).
3. Lower the roller into place.
4. Turn the roller so that the line marked on it faces the inside of the room. To set plastic windows to summer mode, the roller should be turned towards the street, loosening the degree of pressure.
5. All of the above must be done with each roller that is present around the perimeter of the sash or door.

If you are still not confident in your abilities, then in such a situation it is better to seek the help of specialists. However, be prepared for the fact that you will have to pay for their services, taking into account the technician’s visit to your home.

Concluding this topic, we will give you some more useful tips Regarding the modes of plastic windows:

1. If the seal is worn out, it must be replaced with a new one.
2. It is highly not recommended to leave the fittings in permanent winter mode. It needs to be adjusted periodically according to the time of year.
3. Be careful in setting up. If you adjust the fittings incorrectly, the window may break. As a result, you will have to “fork out” for a full repair of the product.

By properly calibrating the fittings, you will be able to maximize its service life and service life. rubber seal. To put it more briefly, the principle of the modes is as follows: in the warm season, the degree of pressure on the sash should be reduced, and in the cold season, accordingly, increased.

Reasons for blowing unrelated to the modes of plastic windows

Among other existing reasons for the blowing of plastic windows, the most common are: poor-quality installation of the structure or defects in the manufacture of the product. For poor-quality installation, claims must be made to the company that actually installed the structure. In the event of a manufacturing defect, responsibility falls entirely on the manufacturer. In such a situation, claims must be submitted to the organization where you purchased such a window.

If we consider the reasons in more detail, we can highlight the following points that contribute to the blowing of plastic windows:

1. The window profile cracked due to the fact that it was made of low-quality plastic.
2. Incorrect calibration of fittings. This leads to the fact that the sash is not pressed tightly enough against the frame, as a result of which blowing occurs.
3. A loose glazing bead that does not securely hold the glass unit. A similar problem in most cases occurs in winter - it is at this time that the product decreases in volume due to low temperatures. Often, as a result, the glazing beads jump out of the grooves.
4. Poor quality fixation of the structure on foam.
5. Incorrect fastening of the frame in window opening(insufficient sash overlap to the window appears).

Of course, all of the above in no way gives you a reason to panic. These faults must be corrected by the company that installed the product. If something happens, some components can be replaced due to their malfunction - warranty service and consumer rights will be your trump card in such a situation.

The main advantages of plastic windows

If the product was manufactured with high quality and its installation was carried out in compliance with all modern technologies, then the design will act as an iron guarantor favorable microclimate in the room where it is installed. The main advantages of plastic windows include the following:

• They are warm. Due to their tightness, the products eliminate the need for additional thermal insulation.
• They are sealed. When closed, the structure does not allow random gusts of wind and drafts to pass through.
• They are effective. Thanks to plastic windows, it is possible to raise the room temperature to five degrees without resorting to additional funds heating.
• They are persistent. Thanks to metal reinforcement plastic profile, the stability and strength indicators of the window are kept at a fairly high level.
• They are universal. Quality designs They cope well with all the responsibilities assigned to them. When choosing PVC windows, you will forget for a long time what annual insulation of openings is. In addition, there is no need to paint these products and constantly care for them - all you need to do is wipe them occasionally with a damp cloth.
• They are durable. A good product can serve you for more than forty years without losing its quality and color.

If the structure installed in your apartment does not correspond to any of the above points, you can safely send a claim to the manufacturer. A truly high-quality plastic window must fully comply with the previously stated characteristics.

Additional window insulation for winter

Plastic (even High Quality) windows with high level thermal protection and high-quality waterproofing in winter they are susceptible to both sweating and freezing. This is not at all a sign of defective or incorrect installation. Most likely, you simply did not take care of the proper seasonal preparation of your own windows.

Today we will talk about this current topic. So, how to switch plastic windows to winter mode, get rid of drafts and achieve additional insulation ram? To answer this question, let’s take a closer look at all the “weak points”.

Winter mode of plastic windows and fittings

About her - first of all. Mostly modern windows equipped with fittings designed for 2 or 3 seasonal modes. This is either “summer-winter” or “summer-winter-autumn”. Some window owners are not even aware of this and when it gets colder they begin to curse the “hack-working” manufacturers. But we will correct this misunderstanding - we will talk about how to switch plastic windows to winter mode. The photos posted in the article will help the reader in terms of clarity.

Most often the situation is fixable: it all comes down to turning a couple of bolts. We switch our windows to “winter” and forget about the problems. To do this, pay attention to the pivot pin. What it is? A pin is a miniature mechanism with which the sashes can be held in the slammed position, most often its location is along the perimeter of the window. Remember the click when the sash slams shut? It was the trunnion that worked.

How to find her?

It may look like a ring or an oval lever. If this ring is in the form of a nut, there is a hole mark on it. Check: when it is located close to the frame with the seal, this is winter mode. This ensures the greatest possible fit of the sash to the profile. Why you shouldn't use it all year round? Yes, simply because the seal will quickly wear out and go into circulation.

The trunnion (given its oval shape) is adjusted very easily, without any tools. In the form of a nut - using a hexagon. By turning the ring with it, we achieve the movement of the small circle-mark closer to the seal. Going back to “summer” is as easy as switching plastic windows to winter mode - by turning the ring.

Handles and hinges on the eve of cold weather need to be lubricated by machine or vegetable oil or special means from a tube-syringe.

Let's take care of the seal

We are talking about a rubber gasket between the sash and the frame. It is also considered a sealant for the edges of glass units. At the end of autumn, feel it around the perimeter and make sure it is elastic, especially in the corners. Normally, it bends easily and quickly takes its original shape.

If this is not the case, it is impossible to revive it by any means; you will have to change it. If everything is in order, then before you switch the plastic windows to winter mode, take care of its preparation by purchasing it in an aerosol or tube with a syringe.

The lubricant is applied with a brush to a well-washed and dried seal (it is better to use dish gel, but not alcohol or abrasives). If the sealant is multi-petal, first place the product between the petals.

Don't forget about the sealant around the edges of the glass unit. If there is no bead in this part of the window (not provided for by the design or simply broken), the glazing seal is lubricated in the same way as usual.

What to do with seams?

We are talking about the seams between the profile and the window opening. This is where the main heat from the room “leaks away”. Before switching plastic windows to winter mode, make sure there are no drafts. In addition to the latter, condensation and even ice on the window will indicate damaged thermal insulation. It will help to get rid of these problems additional layer polyurethane foam. Even more reliable - plastic plates or drywall in combination with mineral wool.

It is not recommended to insulate plastic windows using “folk” methods - cotton wool, homemade putties, etc. Most of these products are not only ineffective, but can also cause harm - fabric and cotton wool retain moisture inside, which leads to fungus and condensation, and covering the crack with wax or melted paraffin, you risk damaging the factory seal.

How to switch plastic windows to winter mode (roto)

We are talking about a popular product widely known to the consumer market in various modifications and supplied various manufacturers in many countries. The principles of its adjustment are the same for any model.

How to switch plastic windows to winter mode if you have such fittings? Modern models are adjusted with a 4mm hex wrench, older ones with pliers and a screwdriver. What are the main problems that require our intervention?

If, when closing the window sash, we touch the frame below, it is sagging. A slight lift is required: remove the protective cap from the bottom hinge (at the top), using a hexagon inserted into the recess, raise (rotating clockwise) or lower (counterclockwise) the frame a couple of millimeters. Usually this is enough.

When the sash “collides” with the frame in the middle part, you need to adjust it in the horizontal direction. This is done with special screws on the upper and lower hinges. If you rotate them clockwise, the sash will come closer to the hinge (the interference will decrease), and counterclockwise, it will move closer to the frame. The displacement is possible no more than 2-3 mm. We deal with distortion in the same way.

Other problems

If, despite this, you still feel a draft (it’s simply blowing from the window), better pressing of the sash is achieved with eccentric locking pins (you can detect them by looking at the end of the sash in the open position).

Some ROTO fitting models contain several adjusting eccentrics; try to act on them evenly.

If suddenly, when opening quickly, the lock did not work correctly, and the handle got stuck in the middle position between the open and tilted window modes, find the “clip” (tongue) below the handle itself and turn it parallel to the seal. The handle will be able to turn smoothly. Does not work? This means that the contact of the tongue with the lock is broken - unscrew the mechanism and place a thin plate inside so that the parts can come into contact again.

Sometimes it happens that the handle is simply loose or needs to be replaced (you decided to install a “children’s” lock). Rotate the bar that covers its base by 90 °C, unscrew the screws and install a new one. If replacement is not needed, just tighten them.

Don't forget about caring for your fittings

In order for the mechanism to serve for a long time and efficiently, the fittings need lubrication. To do this, take silicone or automotive lubricant WD-40 and apply it to the points of contact. This should be done at least once a year, before switching plastic windows to winter mode, and preferably twice as often.

Others, more complex problems require calling a service technician.

The approach of winter brings with it a noticeable cooling.

And switching plastic windows to winter mode will reduce heat loss from the house. You can perform this operation yourself. Switching windows to winter mode does not require large quantity tools and special skills. Our article describes in detail the sequence of actions that are understandable even for people without technical skills.

What is winter mode in windows?

Modern plastic windows have several functions that allow you to control and regulate the microclimate in a living space. Manufacturers and sellers do not always inform buyers about availability given opportunities plastic windows. Self-study their characteristics and a careful inspection of the frames will reveal the presence of an eccentric, which regulates the fit of the window sashes to the frame.

Most apartments are equipped with plastic windows. Indeed, they are easy to use, durable, have various sizes and can be of varying degrees of insulation. However for the right choice Such a window will require proper measurements. will help you correctly take the appropriate measurements yourself.

Plastic window modes

There are three modes, differing in the position of the valves and characterized by maintaining different temperatures:

• summer - this mode is recommended to be installed on frames in the spring and before the onset of autumn. The loose fit of the sashes to the frame allows for sufficient air flow into the rooms;
• winter, which is installed with the onset of cold weather. The tight fit to the frame makes it possible to minimize heat loss from the room;
• The standard position is characterized by the middle position of the eccentric, which regulates the degree of fit of the sashes to the frame. It can be left for the whole year due to the most optimal air flow into the room.

Due to deformation of parts of the product under the influence of temperature and humidity, correcting the fit will reduce the degree of wear on window parts.

When to set winter mode

The onset of cold weather can be considered the reason for changing the regime in a plastic window.

However, the following situations should also be considered reasons why it is recommended to switch windows to winter mode:

• blows from the window. In the summer, such blowing entails excessive dust entering the apartment, and in the winter - a decrease in the overall temperature in the apartment;
• sash sagging. This defect can be eliminated by replacing the fittings or tightening the hinges. A tighter connection of the sash to the window frame, that is, winter mode;
• poor closing or opening of the window. This may result from an incorrectly set window mode.

The listed reasons should be considered a sufficient reason to switch the window to winter mode. The process of setting this mode is described in the next chapter. Correctly performing the above steps will allow you to maintain the normal functioning of your windows for a long time and will ensure warmth and comfort in your home.

Switching windows to winter mode

Often, owners of plastic windows call an employee of the company from which these windows were purchased to transfer them to a certain mode. However, if you carry out the necessary actions correctly, you can independently set the required window mode.

Sequencing

Before translation, the location of the trunnions should be determined. The number of eccentrics depends on the size of the sashes and windows. You should find all of them, because when you switch to a certain mode, you need to adjust each of them.

Usually there are three of them on the side where the handle is located, and one on the opposite side, where the hinges and awnings are.

• Before exposure begins, all fittings should be thoroughly cleaned. This will keep her from mechanical damage, will ensure flawless functioning in the future;
• Apply lubricant and wipe again. This action will allow the translation to be carried out more accurately. Prevention of possible breakdown of the window mechanism guarantees the expected result: blowing, dust entering the room;
• after transfer to desired mode the mechanism can be re-lubricated;
• carefully examine the eccentrics. You should find all the marks that mark the modes. This is usually a stripe and the position of the trunnion relative to the horizon line;
• Now you should directly transfer to the desired mode. A hexagon or pliers can be used for this. The oval-shaped eccentric is more convenient to move using pliers.

After completing the manipulations, you can check the degree of air penetration into the room as follows. Place a thin piece of paper between the flaps closed window. If it vibrates or flies out of it, it means the window is in summer mode.

It must be remembered that some manufacturers of plastic windows have eccentrics recessed into the sash. Before carrying out manipulations to switch the mode, you should first pull it out.

After completing the transfer to the desired mode, set it to the original mode. It is most convenient to perform this action with pliers.

Winter mode is usually marked with a flat line, which is turned inward. If the trunnion is oval-shaped, then the dash or dot should be located horizontally. This general requirement to all types of plastic windows that have the function of switching to different modes.

The instructions contained in this article will help you find out what position the trunnion is in and figure out how to switch the windows to winter mode without calling a technician to your home. The text provides an overview of the features and characteristics window fittings, tips for its use and correct adjustment, as well as visual video material and photos with a clear description of this procedure.

Metal-plastic double-glazed windows are widely used for glazing apartments and private houses. Such designs have the ability to make adjustments and set the degree of pressing of the sash. Thanks to this window adjustment PVC system can be switched to winter or summer seasonal mode. This function is very convenient, although not all owners know about it.

The availability of the adjustment function depends on the type of fittings used. This feature is not inherent in every type of window, but only in modern modifications. There are several modes. Each of them has its own characteristics.

Standard, summer and winter modes of plastic windows

The standard mode assumes the middle position of pressing the sash. This means that the eccentric will be located in the middle. A window structure installed in this mode, in most cases, is able to work effectively both in winter and in summer. This ensures an optimal level of compression of the sealing material.

In winter mode, windows are characterized by a tighter fit of the sash to the frame. Thanks to this, during the cold season, metal-plastic structures effectively retain heat, keeping it indoors.

Summer mode is characterized by less tight fixation of the sash. In this position, air flows circulate freely between environment and the room. In other words, a micro-ventilation effect is ensured, due to which optimal microclimatic conditions are maintained in hot weather.

Note! Using the summer mode allows you to weaken the shutters as much as possible, which has a positive effect on the condition of metal-plastic windows that have survived a long winter. At the same time, it remains possible to protect the room from dirt, dust and heat.

Why is it necessary to adjust plastic windows for summer and winter modes?

Switching from one mode to another allows you to save window design in functional condition and extend its service life. Adjustment involves changing the degree of fit of the sash to the window frame. During the winter season insulation material It contracts, and in the summer it expands. It, like all fasteners, can be protected from wear with the help of adjustment, video and photographic materials with instructions describing how this can be done are available on the Internet.

Sometimes during operation the sash shifts. When it is warm outside, this does not cause any inconvenience, but in winter this can cause the room temperature to drop significantly. If this happens, you should check the condition of the frame. When installing metal-plastic windows, craftsmen check the position of the sashes in each mode, as well as the absence of gaps between the parts. However, a perfectly executed installation does not guarantee that the sashes will not come apart over time.

If the window installation is completed in early spring or in winter, structures are exposed to external influences:

1. The temperature outside is rising.
2. Under the influence of climate change, plastic begins to expand.
3. The temperature outside is dropping.
4. Influenced temperature changes plastic decreases in volume, but it is not always able to take its original shape.

Similar processes occur if windows are installed in the summer. But first the material contracts as temperatures drop, and then expands. However, it is impossible to avoid changes in technical specifications products, so gaps often appear in the windows.

The need to switch plastic windows to winter or summer mode may be due not only to the seasonal transition, but also to a number of other reasons:

1. Drafts from the window, carrying frosty air in winter and dust in summer.
2. Sagging of the sashes due to wear on the hinges.
3. Sash jamming in ventilation mode.

Note! During operation of windows, the sealing material is subject to severe wear. Therefore, it is very important to promptly adjust plastic windows with your own hands when switching to winter/summer modes.

How to check the possibility of adjusting plastic windows for the winter

The ability to switch between summer and winter modes is provided by special fittings. The availability of this function depends on the class of these parts.

There are several types of components:

1. Budget fittings - parts that have the most low cost and are solely responsible for opening and closing the window structure.
2. Standard fittings – the kit contains standard and burglary-proof parts that allow you to prepare the window structure for summer or winter.
3. Specialized fittings - includes anti-burglary and specialized parts that allow you to switch plastic windows to winter or summer mode.

Most modern manufacturers produce standard and specialized fittings with the function of switching from one mode to another.

The most popular brands:

• Siegenia Aubi;
• Maco;
• Roto.

During installation, the user is not always given detailed information O functionality fittings filling. To find out whether the window design provides a transition between modes, you should study appearance and marking of the configuration, namely, the axle.

An eccentric or trunnion is one of the elements of the fittings that allows you to adjust the degree of pressure of the sash to the frame of a metal-plastic window. This item placed on the side.

If the trunnion contains special holes intended for a key, then the design has an adjustment function. This can be easily seen even in photos of plastic windows, of which there are many on the Internet. As a rule, the marking is marked with the image of a hexagon, screwdriver or asterisk. In some cases, the control part has an oval shape, which also indicates that the window can be operated in different modes.

How to determine which mode of plastic windows is set: winter or summer

Before adjusting plastic windows for the winter, you should determine in what position the fittings are installed. There are several ways to help you find out how the sash is placed. In each case, the technique depends on the shape of the trunnion.

How to determine the winter mode of plastic windows before adjusting the fittings:

1. Take a sheet of paper.
2. It is placed between the sash and window frame so that one of the ends remains on the side of the room.
3. The window closes.
4. Then you should pull the sheet towards you.

If the paper passes easily, it means that the structure is set for operation in summer mode. Otherwise it will tear.

Helpful advice! Manufacturers metal-plastic structures It is recommended to operate windows in summer mode all year round. If there is no reason to switch to the winter position of the sash, this procedure is not necessary.

In addition, there is a way to visually determine whether winter mode is installed on plastic windows; photo examples with markings can be easily found on the Internet. According to this method, it is necessary to find a marking in the form of a dash, asterisk or dot on the round pin. Next, you need to determine the direction of this mark. If the marking points towards the room, it means that the windows are set to summer operation. If the mark faces the street, then the design is set to winter mode.

Trunnions are not only round, but also oval. The operating mode in this case is determined by the nature of the eccentric placement. If it is turned vertically, then the windows are set for summer weather. In a horizontal position, the trunnion presses the sash as tightly as possible to the frame, which indicates winter mode.

Having determined the position of the sash, you can move on to solving the question of how to switch the windows to winter mode; video instructions describing this procedure are presented in large quantities on the Internet.

How to adjust plastic windows in winter/summer modes: video review and description

To find out how plastic windows are adjusted, it is advisable to read the manufacturer’s instructions, study descriptions and video materials, which can later be used as visual material. If the work is carried out without the help of a specialist, it is very important to fully understand the essence of the issue and act as carefully as possible, since there is a risk of damaging the fittings with a careless movement.

How to set windows to winter modeoperation: photoand description of the preparatory stage

Preparing the window for customization begins with cleaning. To perform this procedure, you will need a certain set of tools and devices.

This list includes:

• mop equipped with a telescopic handle;
• a product intended for cleaning window glass;

• paper napkins or towels;
• a product intended for cleaning accessories;
• silicone-based lubricant;
• brush or hard brush.

Helpful advice! If you constantly take care of your double-glazed windows and keep them clean, before you adjust your plastic windows for the winter, you won’t have to spend a lot of time preparing them.

The preparation of the window structure is as follows:

• glass is washed;
• the frame is wiped;
• dirt on connections and joints is removed;

• use a brush or hard brush to thoroughly clean the fittings;
• all window elements are wiped (especially areas with grease);
• by applying a few drops of silicone grease, the fittings are treated;
• the position of the trunnion is determined;
• the trunnion is set to required position;
• lubricant is reapplied;
• All hinges are lubricated.

After all the above manipulations have been completed, the result is checked using a sheet of paper.

How to switch windows to winter mode: photoand recommendations

To adjust the fittings on double-glazed windows you will need special tool. Experts recommend having with you:

1. Pliers.
2. Screwdriver.
3. Hex key.

The necessary tools should be purchased immediately after purchasing the windows, since the need to adjust them may arise suddenly. Sometimes the eccentrics do not protrude outward, and many owners search the Internet for videos on how to adjust plastic windows with similar features. The secret is to pull the pin outward. After this you can already configure it. When the eccentrics are installed in the required position, they should be recessed into the sash again.

Experts do not recommend changing modes during the first year of window operation. In new designs, the sealing material has not yet been subject to wear, so the mechanical loads on the fittings should not be increased or adjusted. If the winter in the region is not too different low temperatures, operation of double-glazed windows in summer mode is allowed. While winter adjustment It should not be left in the summer, since this mode will cause accelerated wear of the seal.

Note! Changing the regime is allowed no more than 2 times a year. Moreover, the length winter period operation is much shorter than the summer one.

Setting up plastic windows: how to adjust the sashes horizontally and vertically

Regardless of the mode of operation, the doors of the structure are not allowed to be skewed. Sometimes you have to resort to correcting their position in order to correctly configure the fittings. The presence of sagging or misalignment reduces the service life of the seal. To work, you will need a pencil with a soft lead and a ruler. All manipulations with the window must be performed extremely carefully, otherwise the plastic can be damaged.

Preparing the window for adjusting the sashes:

1. The structure is closing.
2. The sash is traced around the perimeter using a pencil (marks are applied to the frame).
3. The window opens.
4. The distances between the frame opening and the marked lines along the entire perimeter of the structure are measured.

The indicators should be the same on all sides. A slight deviation is allowed, but not more than 7 mm. If the level of the left edge is too low relative to the right, or vice versa, you need to adjust its position. To do this you will need to remove decorative insert and tighten the screws that are installed at the bottom.

In some cases, it becomes necessary to raise the sash. To do this, unscrew the top screw halfway. If the level of the sash is too high, the fasteners are tightened ¼ turn. If it is clearly underestimated, the bolt is unscrewed by ¼ turn. The wings are adjusted horizontally using screws located on the hinges.

How to adjust plastic windows horizontally:

1. The window opens.
2. There is a hole whose configuration corresponds to a hex key.
3. The screw turns smoothly until the sash is aligned to the required position.
4. Check in progress.

To check the quality of the setting, close the window structure. If you need to reduce the distance between the hinge and the sash, the hex key must be rotated clockwise. If the distance between these elements is too small, then the tool is rotated counterclockwise.

Important! A strong horizontal movement of the window is not allowed. The maximum allowable value is 3 mm (in either direction).

Possible problems with metal-plastic windows and ways to solve them

You can check the quality of the work performed not only with a sheet of paper, but also by ear.

A well adjusted window behaves like this:

• nothing interferes with the free opening of the doors; they close without hindrance;
• there is no creaking, grinding or other extraneous sounds;
• all the screws holding the sash in in the right position, screwed in approximately the same way;
• along the entire perimeter of the window, the sealing material has the same thickness and shape;
• after opening/closing the sash, the sealing material returns to its original shape.

Changing the operating mode of a structure is sometimes accompanied by problems. If the roller does not turn, it may need to be pulled out of the groove on the latch by turning it 90°. If this does not help, the part needs to be lubricated with WD-40. This lubricant comes in the form of an aerosol mixture in a can. It is designed for processing joints and threads.

If, when switching to winter mode, drafts from the window do not disappear, it means that the service life of the seal has expired. It is very easy to replace this material. It is enough to remove the old seal from the frame and grooves of the sash and insert a new one in its place (by hand or using a dull spatula). Since the material is welded to the profile in the corners, you will have to trim it to remove it.

The information contained in this article clearly explains how to set windows to winter mode. Videos, photographs and detailed descriptions procedures allow you to fully understand the features of adjusting double-glazed windows. Using this data, you can quickly and easily provide warmth and comfort in own home when it's cold outside the windows.

On the one hand, such manipulations promise benefits by reducing heat loss through the window structure, but on the other hand, as a result of adjustment, the seal quickly wears out.

How to switch plastic windows to winter mode: video-instructions

This summer, new plastic windows were installed in my apartment. The installer warned that with the onset of cold weather, the windows would need to be switched to the so-called winter mode. He told and showed how to do this. I am sharing with you how to adjust windows for winter and summer with your own hands.

Need for adjustment

Adjusting windows is a mandatory procedure not only after their installation, but also when the seasons change. Since modern double-glazed windows are endowed with the ability to pass air, in the summer the flow of air masses can be increased, and in winter it can be reduced.

In addition, with long-term use and without proper prevention, plastic windows may perform their functions worse. In such situations, adjusting the windows will help - it’s easy to do it yourself.

Reasons for decreased performance of double-glazed windows

Reason 1. Change of seasons

Adjustment of the pressure of the sash to the frame is carried out using a small mechanism - a pin. In addition, the locking pin allows you to increase the reliability and safety of the structure (it is much more difficult to break into it from the outside). The amount of air entering the room depends on the position of the trunnions.

First, let's find out what a trunnion is and what it looks like. Common options are presented in the table:

Image	Description
	Option 1. Standard shut-off. Can be adjusted using a hex wrench, slotted screwdriver or by hand. This is the most common type of trunnion.
	Option 2. Eccentric roller with a notch. Adjustable without the use of additional devices. You can change the mode yourself.
	Option 3. Anti-burglary. Can be adjusted using a 4mm hex wrench or a special trunnion wrench. The price of windows with installed anti-burglary fittings is significantly higher than their analogues.
	Option 4. Mushroom-shaped. You can change the position special key for such accessories. When installing windows you will be required to provide such a key.

The table describes how to change the window mode using the example of an eccentric roller with a notch:

Image	Instructions
	Mode 1. Summer: Open the window. Turn the window handles to the “Ventilation” position. To loosen the pressure, rotate the roller counterclockwise several times. The notch should be on the left.
	Mode 2. Autumn (spring): Repeat the first 2 steps from the previous method. Depending on the starting position, turn the trunnion so that the notch faces up. Usually, when installing windows, the middle position is set.
	Mode 3. Winter. Adjusting plastic windows for winter is almost the same as for summer. The only difference: the trunnion must be turned clockwise. The notch should face to the right.

It is advisable to set the “plastic windows - winter” mode with the first frost. Such manipulations will better retain heat inside the room and reduce wear and tear on window fittings.

Reason 2. Problems with the performance of the sashes

Let's consider the main reasons for sagging sashes:

• Heavy weight. It is not recommended to keep large windows open for a long time. The doors lower under their own weight.
• Incorrect installation. It is possible that mistakes were made when installing the window sash.
• Improper use. Hanging anything on the windows to dry is highly undesirable. There is no need to intentionally add weight to an already cumbersome structure.

Algorithm for how to independently restore the correct geometry of the valves:

Image	Description
	Stage 1. Remove glazing beads We insert a knife with an oval blade into the gap between the frame and the bead. We push the knife all the way and run it along the entire length of the bead. We take out the glazing beads (long ones first, then short ones).
	Stage 2. Remove the glass unit Prepare a substrate that will be used to level the frame under the double-glazed window. Hold the glass unit, make sure that it does not depressurize. Place the substrates on top of the glass unit and adjust to the required size.
	Stage 3. Hammering glazing beads By using rubber mallet return the short beads to their place. Now you need to install the long ones. Finally, hammer around the entire perimeter one more time.

Reason 3. Friction of the valves

There may be situations when, during use, grinding, creaking and friction of the internal mechanisms of the windows are heard. This problem can be eliminated by adjusting the special screws located at the top hinge. To do this, you need to open the window 90° and insert a hex key into the screw (example in the photo below).
