When renovating any house or apartment, an important step will be to replace obsolete wooden window structures on new plastic windows... A change like this tends to make dramatic changes in external appearance the whole room, that the owners of the apartments only think about why they did not do it earlier. In addition, thanks to this design, it is possible to significantly reduce heat loss and protect yourself from street noise. In strong heat, the room will not be very hot, while maintaining an optimal microclimate inside the room.
However, due to such tightness, the apartment may also be broken. V apartment buildings Soviet-built ventilation channels do not always cope with the increasing load, so you need to know about what kind of supply ventilation on plastic windows is.
Most designs of modern housing stock represent the simplest ventilation systems which consist of an ordinary kitchen hood or a hood installed in the bathroom. The inflow of air masses is ensured by the slots in the window and doorways... This option is successfully used in houses in which conventional wooden boxes... In the event that you install a set of plastic windows in such a house and install door seals, then the inflow of air masses becomes too limited, which can lead to a violation of the microclimate of the room and also:
- Significantly increase the level of humidity, which makes it difficult to stay in the room due to the strong stuffiness.
- There is a pronounced discomfort in the rooms associated with a lack of fresh air.
Sidebar: Important: Due to the lack of fresh air, such an unpleasant effect as "overflow" can occur, when, due to the lack of air in the ventilation shaft, a lot of odors from neighboring apartments begin to penetrate into yours, which, of course, is an extremely undesirable "side effect".
The ventilation system of plastic windows has a number of its own characteristics. Many people note that in addition to a draft-free system, they begin to have problems such as strong fogging of glasses and stuffiness.
In the event that users have complaints against the manufacturer, then most often a recommendation is given to open the doors, setting them to the "ventilation mode". However, in this case, the advantages of the system are not fully understood.
It is recommended to start dealing with the problem of airing the room at the stage of purchasing plastic windows. When contacting a company that implements such designs, you must inquire about the following features:
- Is there a window.
- Is there a "comb". Although the cost of such a device is small, the benefits of its use are quite tangible.
- Is there a ventilation valve in this design?
- Is there a possibility of self-ventilation ..
Comb. Thanks to this device, the sash can be adjusted to the desired position. This design has a number of differences from the usual folding mechanism and allows you to independently adjust the opening width of the flaps in various positions.
Thanks to the use of the vents, the normal operation of the whole can be guaranteed. Air entering the upper space of the room mixes with the air in the room, spreading directly through its volume. The main disadvantage is the fact that, due to the complicated design, the price for such a window increases significantly. At the same time, the luminous flux in the room is slightly, but still decreases.
Self-ventilated windows. For their manufacture is used special view a profile that has holes in the outer and inner top elements. This ensures the flow of air masses into the upper part of the room. The design of the window provides for the presence of a special chamber that carries out the movement of the air flow, which returns to the space of the room, having passed through the heating.
There are certain restrictions. For example, those who live on high floors are not recommended to install a wider and more expensive profile. In this case, a weak thrust will not be able to provide an inflow of air masses in the required volume. During the heat full-fledged work the system will be difficult, and it will not be able to work due to the peculiarities of the convection process.

To maintain a normal microclimate both near plastic windows and throughout the room, it is necessary to use special ventilation valves, which are universal devices.
Today they are used following ways installation:
- Replacing old double-glazed windows with new ones, which are smaller in order to install a ventilation valve in the vacated space.
- A valve that is located in one of the elements of the upper window sash.
The first method has certain disadvantages. In particular, the luminous flux decreases, which increases material costs for additional sources lighting. Professionals advise using the second option, which is implemented in a short period of time (no more than half an hour) and at the same time is cheaper.
There are options with automatic and manual control. It is advisable to avoid variations in which the valves cannot be adjusted. Manual control is not only more cost-effective, but also allows for convenient airflow control and reduced heat loss. Thanks to the automatic mode, you can constantly maintain a certain humidity and temperature in the room.
The best option is to combine the two options, since the best results can be achieved with a combined control system.
The outflow and inflow of air must be carried out in accordance with the norms of air exchange. In order to achieve the best sound absorption, ventilation valves with similar capabilities and technical characteristics are installed on modern window structures.
Since during operation in the cold season, difficulties often arise, since it is not always possible to predict the appearance of ice, condensation, or. In order to remove certain "risk factors" it is recommended to do the following:
- Ensure high thermal insulation of the valves, paying particular attention to the part located outside the room.
- Install a "thermal break" made of plastic in the event that a metal case is used at the moment.
The valve is a rather complex device, so its price can be quite high.
- Slotted valves are available in both mechanical and automatic versions. The room is ventilated by the penetration of fresh air through ventilation ducts... The advantage of slotted valves is that they are easy to install and provide normal air exchange without the need for dismantling.
- The seam valves allow for a normal flow of fresh air, which is carried out thanks to the seam cutouts in window blocks... They are characterized by low bandwidth and excellent sound insulation performance. At the same time, they have a low cost.
- Overhead valves. They have the largest air flow and have a number of serious disadvantages. For example, they cannot be installed on already installed plastic double-glazed windows, and their use also impairs heat and sound insulation performance.
The use of overhead climatic valves is most common for solving production and industrial problems; in apartment buildings this method is not particularly common. The most common way of installing plastic windows with ventilation is the "binding" method. Regulation of double-glazed windows for ventilation is carried out both in automatic and manual modes. Automatic control allows you to achieve optimal creation and reduce the level of humidity.
Thanks to the use of valves, complete isolation from external noise sources can be achieved and drafts, dampness, condensation and fogging can be prevented. Since mold, dampness and fungi are not the most the best way affect the human body, lowering immunity and performance, then it is recommended to trust the installation of ventilation of plastic windows to real professionals with extensive experience and knowledge in their field.
The control valves do not need special care and maintenance. It is enough literally once a year to clean their surface from dust and various contaminants. For the normal operation of ventilation of plastic windows, the correct functioning of an ordinary hood is necessary. Otherwise, it is disturbed, and condensation can accumulate in the room and the windows fog up.
conclusions
For effective work all the options described above will require an established ventilation system. Despite the fact that the above options allow for the normal exchange of air in the room, there are various factors that can affect it.
The installation of sealed window structures entails a deterioration in the microclimate of the room: humidity rises, there is a lack of oxygen and air stuffiness. Problems can be easily solved by placing the supply valve on plastic windows - the device normalizes natural ventilation and stabilizes air exchange.
We will tell you how to choose the right ventilator to ensure the supply of fresh air to rooms with plastic window frames. We have described in detail the popular models of the device tested in practice. For independent home craftsmen, we provide detailed installation instructions.
The basis of a normal indoor microclimate is the presence of an effective one.
The air must constantly circulate - polluted with an excess of carbon dioxide is removed through the hoods, and clean air comes from outside.

The old imperfect designs did the job efficiently, providing sufficient airflow even in winter. Flaw wooden frames- poor noise and heat insulation
An attempt to restore air circulation by opening a window in ventilation mode cannot be considered a good solution for the following reasons:
- pluses of "plastic" are reduced to zero - the efficiency of the room's thermal insulation is reduced;
- ventilation works only when the window is open, which is especially problematic to organize in the cold season or in windy weather;
- the air flow is uneven and uncontrolled - drafts appear.
Several manufacturers of window systems have taken into account the consequences of complete tightness and have improved the reinforced-plastic structures.
Violation of air exchange negatively affects the health and life of people. Condensation appears on the windows, slopes and walls are covered with mold - the concentration of toxic substances increases
Special ventilation fittings:
- ventilated profiles;
- opening stops;
- partially breathable seals;
- glazing beads with a regulating valve.
To ensure the flow of air through the previously installed window a supply valve is used.
Normal air exchange is essential for any room. However, it is not always possible to install a mechanical ventilation system. The best option is a ventilator for plastic windows. It provides housing with fresh air, which will be constantly supplied, which will eliminate drafts and condensation.
Airing the rooms
The easiest way to ventilate rooms is with open windows. However, it is not the most effective. Together with fresh air, they penetrate into the house harmful substances outside. This is dust and exhaust fumes from road transport as well as cold. Such ventilation is practically impossible near nearby industrial centers.
Now they began to produce PVC windows with micro-ventilation mode... In them, it is enough to turn the handle 45 ° so that a gap appears between the frame and the sash. The outside air will pass through it. With this method, there is almost no noise, and the amount of contamination is minimal compared to an open window. However, the amount of fresh air with such ventilation is not sufficient for the room.
Another good way to ventilate the room is to put a limiter (comb). The system is attached to the window frame and makes it possible to adjust the ventilation gap. This is an inexpensive method, but it does not solve the main problem - access to fresh air. Cold and noise in ventilation mode penetrates the living space.
They also produce designs with a step ventilation mode. Such a ventilation system in plastic windows works like a comb. Turning the knob opens several positions with different sizes cracks.
Self-ventilated windows
After the installation of modern plastic windows, they provide almost complete sealing. Self-ventilated structures were invented for high-quality ventilation. They can be installed in almost all civil and industrial buildings.
In this version, ventilation holes are made in plastic windows. The holes in the profile are at the top and bottom of the frame. Air masses pass through the lower part, after which already heated air enters the room. The system works quite efficiently, but it has some drawbacks. For example, apartments on the upper floors will not be getting enough air. For this reason, special ones have been invented.
Optimal valve options
Such a window ventilation device is considered relatively simple. However, it has design differences depending on the varieties. To understand this, you should know the features of all valve options.
The most inexpensive and simplest are considered to be seam valves. Holes in allow air to enter the room using small cutouts. The features of this design are as follows:
- low price;
- the ability to install PVC windows without dismantling;
- simple and quick installation;
- guarantee of high sound insulation of double-glazed windows;
- possible automation.
Despite all the advantages listed, this type of valve has one significant drawback - poor flow capacity. It feels good when the windows are closed.
In the slotted air it enters through special valves. They are equipped with two blocks: inlet and regulating, and in more modern models only one block of universal type. Among the advantages of the technology are:
- thanks to the regulating block there is full protection from various external factors, for example, precipitation and insects;
- good bandwidth;
- use without dismantling the glass unit.
A serious disadvantage in such valves can be called a relatively complex installation. However, in some models, this drawback is eliminated, for which they are very popular.
There are overhead models, but they are practically not used for residential premises. This is due to the great disadvantages of the valves. They significantly reduce the thermal insulation efficiency of windows, and sound insulation is also completely absent. Such valves are usually installed even before the installation of window structures. This is due to the preliminary adjustment of the opening. In the field of production, this type of supply ventilation is widely used. The demand is due to the excellent bandwidth.
Ventilators for plastic windows
Criterias of choice
During the operation of a ventilated window, it is necessary for the supply ventilation to function efficiently. Each valve option has its pros and cons. To do right choice, the following characteristics should be taken into account:
Experts advise not to consider options in which there is no way to regulate the valve. During their operation, the need to change the air flow is mandatory. Usually, mechanisms are made with manual, automatic and mixed tuning. It is advisable to choose a tandem from the first two. Supply ventilation will be most effective if exhaust ventilation fulfills its function. any design is easy to maintain, and this is another advantage. The main rule of maintenance is cleaning the surface from dirt., which is done once a year.
Depending on the mechanism of the structure, its structure is different. The air flow can be adjusted or it will work in continuous mode... To create an optimal indoor climate, it is advisable to give preference to models with the ability to adjust.
The most comfortable is the automatic setting mode. In such a mechanism, when the optimal parameters change, regulation takes place. A humidity control sensor in the room monitors humidity readings. It can change the cross-section of the air passage in several modes and even completely close the access. This type of control device can significantly reduce heat loss. When there are no people in the room, there is no ventilation.
At manual way ventilation it is necessary to think independently about the regulation of the supply of fresh air. The operating time of the valve is chosen by the person himself in manual mode. Only strong winds are capable of limiting the air flow at this setting.
When operating such a system, drafts occur in the room, which is harmful to health and uncomfortable. A normal supply of fresh air with automatic adjustment will relieve bad health and mood.
They have enough advantages over wooden predecessors. But they also have some disadvantages. For example, perfect tightness saved the dwelling from drafts, but at the same time the microclimate changed for the worse.
A ventilation valve for a plastic window will help get rid of this and other problems.
Is it really necessary?
The loose fit of the parts of the wooden window created constant drafts. And if in the summer it was pleasing, then in the winter it was inconvenient. The older generation remembers how they had to seal the cracks in the fall. But at the same time, the dwelling had an ideal microclimate, there was no stale air. For the same reason, the usual wooden windows do not sweat, and plastic often "cry", which leads to the rapid formation of mold.
Do not forget about the factors of normal life:
Drying of the washed linen in the apartment;
Human breath, emitting carbon dioxide,
Sweating;
Generating steam, heating oils during cooking, etc.
These factors can significantly harm the plastic glass unit. Experts recommend airing the room with such windows 1.5-2 hours a day at any time of the year.
Solid dignity
According to manufacturers, a plastic window vent valve is an ideal device. It does not reduce the amount of incoming light, does not cause drafts, maintains air exchange, creates a constant flow of fresh air, at the same time does not cool the temperature in the room and does not deteriorate one of the highly valued properties of plastic double-glazed windows - sound insulation.
In addition, a constant flow of air keeps the indoor climate at a comfortable level, while ventilation makes the temperature constantly jump.
Design features
The narrow elongated plastic piece is the ventilation valve for the plastic window. The openings from which the air taken from the street comes out are directed upwards. Thanks to this, there are no drafts and the air temperature in the room remains constant.
Valves from almost all manufacturers have several options for operation. Adjustment is necessary to set a specific air exchange mode. There are usually two reasons: the difference in humidity and temperatures in the home and outside.
Air flow control methods
There are two types of ventilation opening settings:
Manual. For this, in some models, a lace is provided (like in blinds), since usually the valve is located high enough. For other devices, the adjustment takes place through the slider. As a rule, its extreme left position completely opens the damper shutter, while the right one blocks the air flow. Therefore, there are usually no questions about how to close the ventilation valve on a plastic window with manual adjustment. The only disadvantage is that it is rather difficult to choose the correct mode on your own.
Automatic. This option is ideal, but you have to pay extra for it. However, the expenses are justified. For example, by saving heat in winter. In the absence of tenants, the humidity in the room decreases and the device reduces the flow of fresh air. Automatic regulation is based on sensors that measure either indoor and outdoor humidity or pressure.
If the automatic option is based on pressure measurement, then the system works as follows. A curtain with an upper suspension is raised or lowered depending on the pressure of the air flow (wind). If the ventilation valve for a plastic window is equipped with a pressure sensor made of nylon tapes, then the adjustment will be carried out by increasing or decreasing the cross-section of the throughput. The system is simple: the more humid the air in the room, the wider the valve opens.
Valve types
There are only three types of ventilation valves on the market:
- Slotted valves. Provide sufficient air flow. It enters through an opening, the width of which ranges from 170 to 400 mm, and the height from 12 to 16 mm. From the street side, the hole is closed by an inlet block. It reliably protects the gap from insects, large particles of dust brought by the wind and from rain. From the side of the room, the hole is closed by a regulating block. This supply valve for plastic windows is installed in the upper part of the sash or in a horizontal dividing profile. The advantages of this type of device are high throughput and ease of mounting, which does not require dismantling.
- Recessed valves. A cheap and simple vent valve for installed PVC windows. The seam valves are supplied into the room through small narrow cutouts in the narthex. The undoubted advantages are the installation, which takes place without special efforts, and maintaining soundproofing. A small disadvantage is low bandwidth, which is why for large rooms folded valves are not suitable.
- Overhead valves. A similar ventilation valve for plastic windows (reviews of numerous customers confirm this) has the highest throughput. But the invoice option cannot be used on already installed double-glazed windows... You need to prepare a place for it in advance.
In shops and markets there is a fairly large the lineup products of this type. They differ in installation methods, the volume of air passed through and other characteristics. The main disadvantage in the use of overhead valves is a significant loss of sound and heat insulation characteristics of glass units. Therefore, experts do not recommend using them at home.
For those who do not want to spoil the window design, the designers have come up with an ideal solution. This is a vent handle for plastic windows. The advantages are significant:
The device is designed to provide natural air flow, which is especially important in the off-season and cold season;
The valve, in combination with the exhaust system, restores the microclimate of the room, eliminating excess moisture;
The handle valve for double-glazed windows is a direct-flow design, therefore, the flow of cold air entering the room does not create condensation, which allows the window to not freeze at low temperatures;
An air filter is installed in the valve, which prevents dust from entering the living space. It needs to be replaced every six months.
How to choose
The ventilation valve for plastic windows (the price starts from 200 rubles) is chosen according to several criteria. Start with the material. It can be metal, wood, or plastic. Another important aspect is the adjustment of the air inlet. The line of inexpensive models does not have this function. They only provide for limiting the air flow when strong wind.
Also, attention should be paid to the efficiency of the device. As noted in user reviews, it is necessary to build on the number of people living in the room. It is believed that one adult family member needs an air flow of 30 m 3 / h.
The sound-absorbing characteristics of the valve to be selected should be close to the corresponding characteristics of the installed insulating glass units.
If you have to do it yourself, it is better to choose a seam or slotted valve.
There are no other special nuances. It remains only to compare prices, find out brands and study the quality of the offered product.
Manufacturing companies
The most popular are devices of the brands Aereco, Air-Box (Comfort, Comfort-S) and Regel-Air.
Aereco models have different air flow rates. Both oblique direction and straight direction can be adjusted. They also differ in great functionality. In addition to their main duties, Aereco, for example, normalizes the humidity level in the living room. The hygrocontrol function is responsible for this.
Air-Box is the leading manufacturer of ventilation valves. Devices from this manufacturer have the best efficiency parameters and are easy to install. They are also compact and relatively cheap.
Domestic ventilation valves are also on sale. For example, a line of these devices was released by the Mabitek company.
Installation of a ventilation valve on plastic windows
There are only two options. The first is global. Complete replacement of double-glazed windows. Moreover, the new one should be slightly smaller, because a valve will appear at the junction of the frame and slopes. Besides high costs there is one more disadvantage - the luminous flux is significantly reduced.
The second option is window binding. The work takes no more than 30 minutes.
Step-by-step instruction
The device can be mounted in the following ways:
On any flap from above;
On the frame;
At the junction of a window and a wall (possible only when installing a double-glazed window).
The easiest installation option is as follows:
- Decide on the place of installation of the valve.
- Attach the device, then open and close the sash. The valve should not rest against the slope.
- Having outlined the attachment points of the device, we make side cuts with a clerical knife.
- We remove the insulation that was installed during the installation of the insulating glass unit and insert the fastening seal.
- We remove from the body of the device protective film and fasten with self-tapping screws to the prepared place.
- We insert the additional seals included in the kit between the fasteners.
- Opposite the installed product, cut out the old seal and insert the one supplied with the valve.
Installing ventilation valves on plastic windows is not particularly difficult.
Care
Supply valve on plastic windows has some peculiarities in operation. It is strictly forbidden to wet and wash it. Disassembling is also not recommended. You can use a vacuum cleaner for cleaning. In the case of general cleaning, construction or finishing works the device must be sealed (for example, with special tape).
The valve is cleaned at least twice a year.
Before the winter cold, it is necessary to properly insulate the valve. Pay special attention to its inner part. If the body of the device is metal, then a plastic thermal break must be installed between the outer and inner parts.
Helpful information
The installation of plastic windows can lead to a violation of the microclimate in the house or office: an increase in the humidity of the environment, a lack of oxygen and musty air. It is easy to eliminate such problems with supply valves for window openings.
TBM-Market has a large selection of window ventilators from leading Russian and world manufacturers. They normalize natural ventilation and stabilize air exchange in residential or non-residential premises.
Advantages of supply valves
The valve consists of an internal adjustable grille and an external visor. The last element blocks rainfall from entering the house and is equipped with a protective mesh from small insects. An internal controlled part allows you to set the amount and direction of movement of fresh air.
The features of window ventilators include the following:
- the light zone of the glass unit remains free;
- no drafts, like from an open window;
- the flow of outdoor air passes organically, in full;
- there will be no heat losses;
- maintaining sound insulation;
- you can set the operating parameters, especially if it is automatic systems;
- easy installation and use.
The ventilation valve looks like a narrow box that is attached to the crossbar of the window opening. Internal parts, called feathers, are responsible for the flow of air from the outside. In good weather, the device lets air flow into the apartment, and in strong winds, the feathers block the cold from entering the room. Due to the fact that ventilation is automatically regulated, there is no need to open windows for ventilation in the morning and in the evening.
Classification
When choosing a supply valve, you can rely on the following criteria:
- Release material:
- metal;
- plastic.
- mechanical adjustment, where the required ventilation level is manually set;
- automatic option, when the element itself determines the opening / closing period of the supply duct, depending on humidity, pressure surges in the room, the number of people in the house, etc.
- Folding mechanism, when air flows through small holes in the valve. It is not necessary to dismantle the window, but the flow capacity of the valve is low, soundproofing qualities may suffer.
- Slotted systems, where air enters the premises through an opening up to 16mm high. Outside, the system is covered with a protective block against small insects and moisture. Inner part represented by a control flap. Installation is carried out on the upper vertical or horizontal crossbar.
- Overhead elements. Installation is not performed on an existing glass unit.
- Wall-mounted mechanism where air exchange passes through a hole in the wall and plastic pipe... This expensive, but also effective device goes on sale already with forced heating or filters for air purification.
- With built-in valves that come with PVC windows.
- With milling, when the element can be purchased after installing the double-glazed window.
- No installation.
- Russia;
- France;
- Germany.
