Modern construction industry developed sealed plastic windows, which are widely used. But, in tandem with natural ventilation, plastic double-glazed windows work differently. When using the built-in macro- and micro-ventilation modes, either the required volume of air is not provided, or a real draft is created. And when the plastic windows are closed, the hood does not work at all and stuffiness appears. Ventilation valve for plastic windows became great solution the problem that has arisen. Without breaking the seal window designs, the valves are capable of not only providing ventilation of the room at full closed windows, but also .
Advantages of using ventilation valves:
- Creation of microclimate parameters necessary for human health.
- Increased service life of premises due to removal excess humidity and preventing the formation, especially of kitchens, balconies and loggias.
- Heat savings due to controlled air flow.
- Security: the likelihood of intruders entering is reduced, because ventilation occurs with the windows closed.
- Ease of use.
Types of ventilation valves
Criteria for choosing window ventilation valves
In order for the operation of the supply ventilation valve on plastic windows to be effective, the multifunctionality of this device is necessary. To determine the class of ventilation valves, there are the following most important characteristics:
- Ensuring the required air exchange parameters: the valve must operate for an influx of outside air equal to at least 30 m3/hour (per 1 person).
- Ensuring the required noise level: for standard plastic windows this indicator is set at 30-35 dB.
- Peculiarities winter operation: this indicator depends on the valve material, the difference between external and internal temperatures, and air flow parameters. For efficient work ventilation valve and preventing its icing, it is important to maintain high-quality thermal insulation of the valve structure and the use of a so-called “thermal break” made of plastic between the outer and inner surface its metal body.
- Control method: it is possible to install supply valves for plastic windows with automatic, manual and mixed regulation(tandem of the two previous types).
- Valve location: exists window and wall installation option. When mounted on a wall, the costs of punching holes in the enclosing structures of the room and disturbing the exterior of the facade by the appearance of foreign elements increase significantly. The window option is more economical, simple and invisible.
- Method of installation of the structure: installation in an existing plastic double-glazed window or by replacing the double-glazed window with a new one and reducing its size.
Advice: You should not consider valves that are not equipped with the ability to regulate, since the need to change the air flow is dictated by practice.
Most popular designs
Aereco window ventilation valves
The French development of the Aereco company has found wide application in Russia. Valve supply ventilation equipped with the ability to regulate by means of a sensor consisting of several polyamide plates, which, when expanded, drive the opening mechanism. Installation can be carried out both in grooves cut in the window block and on the wall of the room.
A special feature of Aereco valves is the removal of the humidity sensor from the valve, which provides a real reflection of the air parameters in the room. The advantages include the absence of the need for any types of energy, laying of air ducts and silent operation. The Aereco line of ventilation valves for plastic windows includes several modifications that differ in the degree of regulation and noise performance.
Air-Box window ventilation systems
The Russian company Mabitek decided to keep up with its foreign colleagues and developed truly universal Air-Box window ventilation valves, which can be installed on window blocks any design. Its undoubted advantage is the ability to install it in the rebate of the window block, which makes the valve invisible.
The standard version (Air-Box Standard) involves the installation of two parts of the valve: the lower external one, which takes air from the street, and the upper one, which supplies the flow fresh air into the room. The principle of operation of the valve is based on creating a vacuum in the room with the windows closed and ventilation running, under the influence of which the valve petals open and a constant air exchange of about 6 m3/hour is created.
Important: Supply ventilation to plastic windows will effectively cope with its task only with properly functioning exhaust ventilation.
This brand also produces a range of noise dampers labeled the Comfort series. They differ in the choice of installation options. Conventional installation involves milling the window profile, while millless installation can be done independently by removing the seal, and it will only take 10-15 minutes. These valves are intended to be manually adjusted. The Comfort S modification is designed specifically for fixed window structures and involves through drilling window block, so direct ventilation is possible.
All Air-Box valves are leaders due to their reasonable cost, efficient operation, relatively small dimensions and simple installation technology.
And about various options films for window tinting on this page.
Valve installation
Professionals use two options for installing ventilation valves. The first involves dismantling the old double-glazed window and installing a new one with reduced dimensions. In this case, the gap formed between the window opening and the block is occupied by the valve itself. This method has significant disadvantages: increased costs required to order and install a new window unit, and a reduction in the area of translucent structures.
The ventilation valve for plastic windows, the installation of which is carried out according to the second option, is mounted in the place of the frame. The convenience of this method will be appreciated by the owners of premises in which sealed plastic double-glazed windows have already been installed. All manipulations to install the valve will take no more than half an hour.
The video demonstrates the installation process of the Air-Box slot valve.
Methods of regulation
Depending on the design of the valve mechanism, the flow supply air on plastic windows with ventilation can be adjusted or have constant parameters. Optimal conditions The internal microclimate of the room will be helped by creating a valve with the ability to regulate, which can be either manual or automatic. The latter type of regulation is more comfortable and carried out based on the readings of the hygroregulation sensor, which monitors the air humidity value in the room. Regulation occurs by changing the cross-section of the air passage channel in several modes, up to complete closure. Maximum cross section corresponds highest value humidity. This type of regulation allows you to reduce heat loss, since ventilation occurs only when there are people in the room and the air humidity increases. When the room is empty and the humidity drops, the valve closes completely.
Choice manual method settings accompanies the need to constantly think about what time to ventilate b, what is the sequence of ventilation of the premises and the opening time of the valve required for ventilation. Manual adjustment can only limit the air flow in gusty winds. This setting is rougher and can lead to drafts in the room.
Care and maintenance
Another integral advantage of ventilation valves for windows is the ease of maintenance. For its comfortable operation, it is enough to clean its surface from dirt only once a year; this is all about maintenance.
In an apartment where plastic windows are installed, there is a low level of heat loss. No noise from the street can be heard. However, such products also have their drawbacks. They contribute to stagnation of air in the apartment and the formation of condensation. This can lead to the formation of fungus and cause various respiratory diseases. A supply valve for plastic windows will solve the problem, reviews of which will allow you to correctly select and install the ventilation element. Advice from experts and ordinary users will help you make the best choice.
Disadvantages of plastic windows
In order to understand the need to install a supply valve, you should read reviews about the main disadvantages of plastic windows.
No drafts compared to wooden windows, is, on the one hand, an advantage of the presented products. However, ventilation must be done by opening the doors. IN winter period This procedure leads to large heat losses.
When the windows are closed, odors and carbon dioxide stagnate in the rooms. Without a supply ventilation valve for plastic windows, according to user reviews, condensation forms and air humidity constantly increases. This is not a healthy state of the atmosphere in the home. A supply valve for plastic windows, reviews of which will be discussed further, can prevent the development of fungus and mold and remove condensation.
In order not to negate all the functions of plastic windows, the presented device should be used.
Main characteristics
The supply valve is a device that performs ventilation functions. It is installed on top of the window sash and is located horizontally. According to reviews from experts and ordinary users, supply ventilation valves on plastic windows eliminate high humidity and condensation, and also maintain a healthy indoor microclimate.
This device has a number of advantages. The fresh air ventilation valve for plastic windows, reviews of which are presented in our review, does not change the light opening of the window. It does not create drafts, there is no heat loss, and no sounds from the street are heard. There is a sufficient supply of fresh air. According to reviews, supply ventilation valves for plastic windows can be adjusted.
One more positive quality The ease of installation of this device can be considered.
Principle of operation
After reading the reviews of expert installers, we can conclude that the supply ventilation valve for plastic windows must be installed correctly in order to fully perform its functions.
Installation involves removing part of the rubber seal on the sash and window frame. Instead, a special, thinner material will be installed. The supply ventilation valve for plastic windows, reviews of which are mostly positive, is installed together with a new seal.
Through the presented device, street air enters the apartment, and damp internal masses are pushed back out through the ventilation ducts. The circulation process occurs due to the pressure difference.
Valve Assemblies
After reading reviews from professional installers about the supply ventilation valve for plastic windows, you can get an idea of its structure. The product consists of several parts.
The outside is outside the window. It takes air from outside. Above outside A visor must be installed to prevent water or snow from getting inside the valve.
Supply ventilation valves for plastic windows, reviews of which were provided by experts, also have a telescopic channel. It passes through the frame, that is, it cuts into the plastic of the frame body and is fixed with a sleeve.
The interior is located directly inside the room. It is a unit consisting of an exhaust nozzle, a simple filter and an adjustment mechanism with the ability to pass air.
Basic job requirements
According to reviews from experts in the field of ventilation technology, fresh air valves for plastic windows work under certain conditions.
Automatic exhaust occurs if the outside temperature does not exceed +5 °C. Otherwise, ventilation stops working, so it should be carried out in a forced manner.
The air supply reviews that we are reviewing today function correctly provided that the ventilation in the apartment is properly functioning.
Also the cracks under interior doors must be at least 2 cm. The entrance door must close hermetically.
Types of valves
According to consumer reviews, there are a great variety of models of supply valves for plastic windows. Depending on the material from which they are made, there are metal, wood or plastic products.
According to the control method, there is an automatic and manual supply ventilation valve for plastic windows. Consumer reviews make it clear that automatic varieties are more convenient to use. They determine independently when to open or close vent. Moreover, the settings can be set based on humidity and pressure drops inside the room.
Manual control involves changing the opening/closing of the ventilation hole using a special rope. The required level is selected The profile may freeze due to incorrect adjustment in winter time. That is why most consumer reviews are inclined to choose automatic supply valves for plastic windows.
Air intake
Based on the method of air flow into the room, there are rebated, slotted and overhead ventilation valves for plastic windows. Reviews from people who have tried the presented devices in their premises indicate the following.
One of the most economical options are rebated inlet valves. In this case, cold air enters through small cutouts in the vestibule. The windows do not need to be dismantled. However, such designs are quite low.
According to consumer reviews, slotted supply ventilation valves on plastic windows have a higher throughput. They are also installed without dismantling the windows.
However, overhead devices allow air to pass through best. Their only drawback is the need to adjust the opening to the size of the valve. If a double-glazed window is installed, this type of product will not work.
Handle valve
The handle valve is a very convenient device. It is installed instead of an ordinary window handle. Among the advantages of this device, it should be noted that there are no changes appearance window.
These are quite interesting supply valves for plastic windows. User reviews assure that the ventilation valve in this case can be located where condensation most often collects on the window.
This is very efficient device to remove moisture. This valve does not freeze, as it has a direct-flow design. The handle valve also has a built-in filter that prevents dust from entering the room.
Valve selection
Among the many variants of models presented on the market of such ventilation equipment, you can get lost.
Manufacturers with a good history and have been existing in the supply valve market for a long time are more popular. These are conscientious companies that have confirmed the quality of their products over years of responsible work.
According to consumer reviews, high-quality supply valves for plastic windows are produced by manufacturers such as Siegenia, Rehau and Aereco.
The main rule when choosing the presented products is not to skimp on quality. You should also understand that the possibility of severe frosts must also be taken into account when choosing a supply valve for plastic windows. Reviews say that if the temperature outside the window drops below - 30°C, then external elements Many structures freeze and there is a constant flow of cold air.
The installation of sealed window structures entails a deterioration in the microclimate of the room: humidity rises, a lack of oxygen and air staleness appear. Problems can be easily solved by placing a 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 describe in detail popular device models tested in practice. For independent home craftsmen, we provide detailed installation instructions.
The basis for a normal indoor microclimate is the presence of an effective one.
The air must constantly circulate - it is polluted in excess carbon dioxide is removed through hoods, and clean water comes from outside.

Old imperfect structures coped with the task effectively, providing sufficient air flow even in winter. The disadvantage of wooden frames is poor noise and heat insulation
An attempt to restore air circulation by opening a window in ventilation mode cannot be considered a good decision the following reasons:
- the advantages of “plastic” are reduced to zero - the efficiency of thermal insulation of the room is reduced;
- ventilation only works when open window, which is especially problematic to organize in the cold season or in windy weather;
- the air flow is uneven and uncontrolled - drafts appear.
Some manufacturers window systems took into account the consequences of complete tightness and improved metal-plastic structures.
Impaired air exchange negatively affects people’s health and livelihoods. Condensation appears on the windows, slopes and walls become covered with mold - the concentration of toxic substances increases
Special ventilation fittings:
- ventilated profiles;
- opening limiters;
- partially breathable seals;
- glazing beads with adjustable valve.
To ensure air flow through previously installed window an inlet valve is used.
The spread of plastic windows has solved the problem of drafts. But it was soon discovered that they had serious drawback– excessive tightness. The solution in this case is the use of special ventilation devices.
Peculiarities
A supply valve for plastic windows is a product that completely compensates for the tightness of the glass unit. Opening the windows a little does not allow for the necessary ventilation. Factories produce millions, even tens of millions of valves every year. If they are selected and installed correctly, fresh air is guaranteed even when the doors are tightly locked. Valves have been present on the Russian market since the late 1990s, but their importance is underestimated by many people.
There is a ridiculous myth that valves are designed solely for extraction additional income manufacturers. In reality, a similar design was invented back in the 19th century. At that time, they were already coming up with solutions for supplying air through supply ducts, with the flow directed as close as possible to the ceiling. This made it possible to avoid drafts. In addition, already at the stage of mass housing construction in the second half of the twentieth century, the equipment of apartments with systems providing fresh air continued.
The developers of this technology knew for sure that widely used wooden windows were replete with cracks, and still continued their experiments. Contrary to another myth, it is not always possible to replace valves with the skillful use of “combs” and slot ventilation. These approaches are a good complement to each other, especially since you can get fresh air mass even in situations where you cannot open the window. It will not be possible to open it slightly in winter if there is a bed nearby, or when it is very noisy outside. Additional motives are protection from thieves, safety of children and pets on the upper floors.
Kinds
A wide variety of plastic windows, the specifics of individual buildings and areas, features of climatic conditions and use ventilation systems lead to a significant range of valves. To adjust the air flow, a number of models use a manual method. Depending on the designers' intentions, laces can sometimes be used (in the same way as for controlling blinds). This is important because the valve itself is often located quite high. There are versions that are equipped with electric motors.
Typically, the leftmost position of the regulator opens the ventilation duct to 100%. Accordingly, the right position corresponds to its complete closure. Difficulties may be associated with selecting a suitable intermediate regime; choosing it without the help of professionals is very difficult. Automated systems They can be quite expensive, but the fees for them are completely reasonable. Saving thermal energy in cold period compensates for all investments.
Automatic type ventilation allows you to track whether there are people in the room, and the ventilation intensity is adjusted accordingly. Such adjustment is made using sensors; depending on the type, they are adjusted to humidity or atmospheric pressure. The system that measures pressure is equipped with a curtain with an overhead suspension. This curtain goes up or down according to the pressure of the air flow, that is, there is no need to use a barometer. Pressure meters are often made using nylon tapes.
The bottom line is that nylon contracts under the influence of moisture, and therefore the air passage gradually increases. Speaking about the division of valves, it should be noted that they belong to one of three groups:
- slotted;
- overhead;
- folded category.
Slit products are able to maintain optimal supply of fresh air. It goes through a channel 17-40 cm wide and 1.2-1.6 cm high. To prevent penetration harmful insects and dust particles, an inlet cover is used. It can additionally stop rainwater from entering the house. Hole with reverse side hoods (inside the building) are equipped with a control system.
Slot valves can be installed in the upper lobes of the valves or in horizontal dividing profiles. The advantage of such products is increased throughput and ease of fastening. If we talk about the rebated look exhaust system placed on PVC windows, important advantages its cheapness and simplicity. To allow air to pass through, narrow, small slits made in the vestibule are used. The seam block has improved noise protection characteristics.
In addition, such structures are very easy to install. Insufficient air passage turns out to be a serious weakness. Therefore, folding equipment is not used in large rooms. If they try to put it there, it will only create a lot of problems. According to the developers (and according to consumer estimates), the overhead climate control unit has the highest throughput capacity.
Its disadvantage is quite serious - such equipment cannot be installed on an already used double-glazed window. It is imperative to prepare the site in advance. In addition, overhead units contribute to the penetration of street noise inside. They don't hold heat well. The general conclusion of experts is for home use such blocks are not suitable.
There is another option constructive solution– supply valve in the form of a handle. This option allows you to avoid violating the design concept of the window. It provides a natural mode of air penetration, which is extremely valuable in the off-season and cold season. Combining the valve with an exhaust apparatus allows you to stabilize the microclimate. Valves in the form of a handle belong to the direct-flow format, and therefore the appearance of condensation in the room is excluded.
Since there is no condensation, the window will not fog up even on the coldest winter day. The valves must be equipped internal filters for air. Their purpose is to prevent contamination of premises with dust particles. These filtration units are supposed to be replaced every 6 months. An important option is micro-ventilation, which helps reduce the need to open windows.
Operating principle
Almost all products for window ventilation able to work without any energy sources. It is enough to use the difference in air pressure in the house and in the open space. But for such a system to solve its problem effectively, the trim must have a decent level. Its optimal value is from 10 Pa. There is no need to independently calculate all pressure parameters, you need to focus only on 3 main criteria:
- full operation of the ventilation system of the house;
- heating the air outside to a maximum of 5 degrees Celsius;
- the ability to move air from one room to another in the required volume.
The last parameter is ensured by the fact that the gap in the intermediate doors is at least 20 mm. Due to the objective principles of its operation, the supply valve does not cope well with ventilation if the days are hot. Each design is designed for a specific temperature range. Deviation from established norms immediately entails Negative consequences. Products with a filter can protect against the harmful effects of polluted air.
Manufacturers: review and reviews
Domestic valves supplied under the brand "Window Filters", are rated very highly by consumers.
Their advantages are:
- excellent noise resistance;
- ability to perform well in the cold;
- dust removal;
- protection from insects;
- reliability during installation.
If we talk about products AirBox, which has already been discussed, the advantages are also obvious - the ability to install it yourself and a reasonable price. Aereco products allow you to adjust the air flow automatically, effortlessly. Regarding designs from "Domventa", they must be placed directly above the battery. Such blocks perfectly contain noise, stop insects, and can be harmoniously combined with the design of the building.
Regarding blocks KIV-125, then they can be either Finnish or Chinese in origin. The structures supplied from Finland are superior to their Asian counterparts with increased thickness and strength. The density of the insulating material also increases. The inner heads are white and dark, respectively. Constructions Vallox also done on the banks Baltic Sea. The company claims that its products fully meet modern requirements. It is characterized by recovery at the level of 75%. These devices are distinguished by their dependence on electrical energy (which is greatly saved). Dust is filtered, and fine particles are also kept out.
The company supplies external type valves with auxiliary heating and humidity detection. During the production process, a leak test is performed. The electronics can be controlled via a smartphone. If necessary, it can be easily supplemented with devices that measure the level of carbon dioxide in the room. Technical description products says that with their help you can even small space ensure receipt clean air and removing dirty air mass without disturbing the roof and ceilings.
Not only the function of removing bad odors and preventing mold contamination is supported. The air in the room becomes drier and gets rid of the characteristic mustiness. The occurrence of drafts is completely eliminated. The inlet channels are equipped with protective filters that 100% stop contamination not only by dust, but also by plant pollen. Therefore, we can conclude that the Finnish complex completely solves the problem.
An equally high-quality product is supplied from Germany. Valves are a convincing example of this. Marley. Their developers tried to provide maximum cover from pollen. For this purpose, an insulating coating of a special brand of foam rubber is formed. Additionally, such a layer prevents the penetration of noise and inhibits the spread of condensation. The cold does not pass into the house, and the heat does not randomly escape outside. The outlet block is designed for walls with a thickness of 25-58 cm.
The manufacturer guarantees:
- smooth (stepless) adjustment of air supply;
- reliable thermal insulation of the inner part of the channel;
- combination of elegance and simplicity;
- the ability to compensate for major installation errors by rotating the hood.
How to choose?
Valves for ventilation of plastic windows can be made from:
- wood;
- become;
- plastics.
The cheapest designs cannot regulate the air supply. The only thing they are capable of is reducing the impact of strong winds. It is very important to determine how efficiently the systems operate. The recommended inflow rate per resident is 30 cubic meters. m in 60 minutes. As for the noise absorption level, it should be the same as that of the plastic bags themselves.
Seam and slot designs are optimal for self-assembly. The disadvantage of overlay elements is visual visibility; if you want to mount a hidden block, you need to choose other designs. Aereco versions differ in the method of air flow. The adjustment can be made in an oblique or straight direction. This company has also managed to provide excellent functionality. Its designs can stabilize the humidity in the room thanks to a special function.
Systems differ in terms of efficiency domestic production Air-Box. In addition, they install well and are not too expensive. Products from Russian companies are gradually entering the market. Among them the best way Mabitek products are suitable. The most widely used polymer windows have noise protection of 30-35 dB. The valve should have a similar level of protection.
It is important to consider that for winter use you will have to carefully select the design according to:
- basic material;
- air flow characteristics;
- differences between external and room temperatures.
In order for the valve to perform its task well, so that it does not become covered with ice, it is required to be equipped with high-quality thermal protection. Additionally, the use of a “thermal break” is required. This gap is formed from a special kind of plastic placed inside the valve. If it is difficult to give preference to manual or automated adjustment, you should choose valves with mixed settings. Designs that are not at all suitable for adjustment should be immediately rejected, because the need for it is very great.
"Air-Box" from "Mabitek" is distinguished by increased versatility and suitability for installation on bags of any design. If necessary, it is placed in folds, that is, completely invisible from the outside. The design of the “Standard” series involves dividing the valve into two parts. The outdoor unit is located at the bottom, and the indoor unit is at the top. The action is ensured by rarefaction of the air; the system will not be able to operate if the exhaust ventilation ducts are not functioning properly.
The manufacturer supplies valves with improved acoustic properties. This family is called “Comfort”. Similar products can be selected for a specific type of installation. The classic approach involves indispensable milling of the window profile. All “comfortable” products are manually adjusted. Valves with a micro-ventilation option allow you to deliver 5-7 cubic meters into the room in an hour. m of air.
Their advantages are:
- protection from hot summer air;
- ventilation without cooling the room during the winter months;
- exclusion of drafts;
- long-term operation;
- stable air exchange without careful adjustments;
- Suitable for maintaining a fresh atmosphere in the absence of people for a long time.
The weaknesses of systems operating in micro-ventilation mode are the accumulation of dust on the surface of the mechanism and the penetration of noise through inexpensive products. It is easier to install devices outside than inside. In addition, working from the outside allows you not to rely on automation, but to set the mode yourself. It is important to find out whether metal parts are sufficiently protected from the formation of an ice layer. Compared to all these characteristics, price parameters are not significant.
In addition to the already mentioned manufacturers of window supply valves, the German brand Siegenia attracts attention. The quality of its products generally satisfies consumers, but there are only a few models that do not reduce the flow of light. A very wide offer of valves is characteristic of the Rehau concern. Moreover, the differences also concern their configuration, and everything works automatically. Reliable, environmentally friendly plastic is used to create the structures.
Part of the ventilation slats contains many chambers. Depending on the current need for fresh air, they open a certain number of holes. But such a solution, with all its seductive simplicity, brings into the rooms, along with fresh air currents, also all the extraneous noise. You can choose this design only if the windows overlook quiet areas of the area. Or in a situation where noise coming from outside will not have a serious negative impact.
Otherwise, you need to choose designs that are regulated by a stable pressure drop. An example of such a product is “Climamat”, which provides regulation of the amount of incoming air and humidity in the room. The device is suitable for full monitoring of the microclimate, for its deep stabilization. Unlike Siegenia analogues, their size is relatively small and there is no need to violate the properties of the window. The system operates silently and filters the incoming air, guaranteed to eliminate drafts. You can purchase a similar valve for any type window profiles. He will also be able to withstand all possible loads.
Even if well-designed and carefully selected valves from leading manufacturers are installed, you will still need to ventilate the room periodically. Same as when purchasing others building materials, components, it is equally undesirable to select valves only according to very affordable price. But there is no point in trying to buy the most expensive product - almost always such expenses are wasted.
Installation
Installing a supply valve with your own hands or with the help of professional installers is possible only in two ways. In the first case, they try to install it when the double-glazed window is completely replaced. The new package should be smaller in size than the old product, since the border of the frame and the slope will be equipped with a valve. The labor intensity of the work is very high, and costs rise sharply. And at the same time, the flux of solar rays is significantly reduced.
According to the second scheme, installation takes place in the window frame. Total installation time is limited to ½ hour. First you need to select a suitable installation position.
There are three ways:
- on top of the frame;
- on top of a separate sash;
- at the intersection of windows with main walls (as mentioned above, this is allowed strictly simultaneously with the installation of the package).
When the point is determined, the device is applied, the sash is opened and closed. At the same time, make sure that the valve does not press against the slope. Once the positions for fastening have been outlined, you need to take a utility knife and make cuts on the side. The insulation material installed during installation of the package must be replaced with a different insulation material. Next, the film located on the valve bodies must be removed, then the products are attached using self-tapping screws.
If the delivery kit includes auxiliary seals, they must be inserted into the gaps of the fasteners. On the opposite side (relative to the valve), the old seal must be cut out. To replace it, use the one included in the kit. It's not too difficult to do this kind of work. But it is important to take into account the features of each design and the manufacturer’s recommendations.
Often, high-quality, flawless installation is only possible in large-scale production conditions. Attempting to install individual valves yourself or inviting specialists does not help matters much. They most often drill the profile several dozen times, practically rendering it unusable. The holes that appear are covered with a valve, and nothing can be seen from the outside. But the reliability of such a design, service life and performance do not withstand even a shadow of criticism.
Therefore, it is much better to buy something that is mounted without inserting into the profile. In addition, such elements are often cheaper and are secured with a screwdriver. And manufacturers give clear detailed instructions, allowing you to almost completely eliminate the occurrence of errors. Let's look at do-it-yourself work using the example of installing affordable valves.
First of all, you should prepare your workspace, freeing it from unnecessary elements. Next, prepare sharply sharpened stationery knives and screwdrivers. Having opened the window, try on the valve on the surface of the frame in the right place. Now you need to cut the sealing rubber with the orientation towards the outer edges of the valve. The part of the elastic band marked with cuts must be removed carefully so as not to break or tear anything. At points where the work plan provides for fastening self-tapping screws, it is necessary to insert embedded-type fastening dowels.
Now it is necessary to integrate a pair of sealing products exactly between the fastening positions. Having done this, they change rubber compressor frames in the right place to the one that is included in the ventilation kit. All that remains is to enjoy the result of your work. All necessary manipulations are completed in 15 minutes. If there are any subtleties or nuances, they are always indicated in the accompanying documentation.
But it is necessary to mention a few more points that are also typical for any model passed through walls. The outer parts of the air intakes must be covered with visors. They block water and various precipitation from seeping into the house. Compact telescopic channels are combined with the housings and secured with a special sleeve. Most valves are mounted on the top of the valves.
Methods of regulation
Micro-ventilation of plastic windows is configured as follows. First, open the sash and remove a certain part of the seal. A knife is used for this purpose. After gluing the gasket included in the delivery set, install 3 plugs. The mechanism is adjusted using a special screwdriver, which is needed to adjust the hinges. If the frost is severe, it is strictly forbidden to close the inflow valve completely. To remove dust clogging the external visor, use a vacuum cleaner. The body itself is cleaned with a damp cloth, both procedures are carried out 2 times a year. Do not clean the valve with synthetic products. If renovations are being carried out indoors, the product must be protected from dust contamination.
When choosing an operating mode, you need to focus on an air speed of 15 cm per second. If the valve closes completely in cold weather, this cannot be tolerated. You will have to seal the external gap that allows air to pass through. Minor extraneous noise should not be perceived as something negative. It's an inevitable companion normal operation devices, especially for overhead structures.
When selecting a valve, the performance range must be assessed based on the current pressure. It is not at all guaranteed that air flow through a valve designed for 15 cc. m per hour at 10 Pa will be higher than through a device designed for 12 m3 at 5 Pa. For stable operation of vent valves in summer period it is required to use an artificial hood supplemented with fans. Must be sealed entrance doors from the side of the street or entrance. The presence of other sources of cold air will devalue the entire system.
Reading time: 6 minutes.
Plastic windows have gained wide popularity all over the world, as they have many advantages compared to outdated ones. wooden frames. They do an excellent job of saving heat, so after their installation, a significant improvement in room temperature is found.
The complete sealing of the windows limits the flow of fresh air into the room, therefore, the structures have two ventilation modes: macro- and micro-ventilation. But, standard designs of ventilation modes have disadvantages: with micro-ventilation, there is an insufficient supply of air, and with macro-ventilation, drafts are formed. To solve the problem, there is special device— a fresh air ventilation valve for plastic windows, which this material will tell you about.
Ventilation valves and their advantages
It is necessary to ventilate the room so that there is sufficient humidity in the room and bacteria do not accumulate in the air.
Let's look at what they have advantages:
- installation of devices is carried out without violating the tightness of windows;
- ventilation is provided constantly with the windows closed;
- no formation of condensation and mold in wet rooms;
- ease of use of products;
- controlled air flow allows you to save heat;
- automatic regulation of fresh air supply, so a person does not need to monitor the ventilation time;
- the likelihood of intruders entering the house is reduced, since the windows are always closed.
The valve design is a plastic device that is mounted on the top of the frame metal-plastic window. Ventilation is carried out automatically - through a built-in mechanism in a plastic case.
What types of products are there?
Ventilation valves are divided into the following types:
- Slotted. These devices are divided into automatic and mechanical. Air enters the room through a channel measuring 170-400*12-16 mm. The advantage of the device is ease of installation, which does not require removing the window frames;
- Seam type valves. The flow of outside air into the room is ensured through special rebate-type cuts. The advantages of the device are its low cost and ease of installation, which does not require removal window frame. The disadvantage is due to: low throughput;
- Invoices. The advantage of overhead valves is that they provide a large volume of air. This results in the following disadvantages: low heat and sound insulation, as well as the inability to install a valve on an existing plastic window.

Air-Box micro-ventilation valve
airbox comfort Air-Box ventilation valves were developed Russian manufacturers. The advantage of the products is determined by the possibility of installation on windows of any design. In addition, the valve can be placed in the rebate of the window unit, which makes the product hidden.
Airbox offers three types of valves: Standard, Comfort and Comfort S.
Airbox standard The Air-Box Standard ventilation valve consists of two structural parts: lower and upper. The upper part of the valve supplies air flow into the room, and the lower part takes air from the street. The operation of the device is based on air vacuum if there is exhaust ventilation in the room. When the windows are closed, the petals of the device open, which will allow air exchange with a volume of 6 m3/hour.
The Air-Box Comfort ventilation valve kit, unlike the Standard one, has one advantage - a noise-proofing function. The devices also differ in mounting options. Installation can be carried out either with or without profile milling. The millless type of installation is carried out independently, for which you will need to remove the seal and install the device. Models of the Comfort S type are often intended for installation on fixed window models, where the window profile is supposed to be drilled.
Air-Box valves have gained wide popularity due to their low cost, high efficiency work, as well as ease of installation. We will find out further how to install a ventilation valve with your own hands.
Device installation
Installation of vented valves is carried out in two ways. Let's consider both options to have an idea of the technology for installing devices.
For the first option characteristic extraction installed double glazing followed by replacing it with a new one, which is smaller in size. A valve is installed in the resulting gap between the glass unit and the frame. The process does not require drilling the plastic structure, but has some disadvantages:
- additional costs, since you will need to not only order a new double-glazed window, but also call a specialist to install it;
- reduction of glass area;
- It is problematic to install the valve yourself.
Second option the most popular and does not require replacing double-glazed windows with new ones. Installation is quick and easy. We'll find out what the installation process looks like below.
