Supply valve for plastic windows: let the apartment breathe! How to properly organize the ventilation of plastic windows, types of ventilation systems Window valve for plastic windows.

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 stale air. It is easy to eliminate such problems with the help of supply valves for window openings.

TBM-Market has a wide range of window ventilators from leading Russian and international manufacturers. They normalize natural ventilation and stabilize air exchange in residential or non-residential premises.

Benefits of inlet valves

The valve consists of an internal controllable grate with adjustment and an external visor. The last element blocks the ingress of precipitation into the house, it is equipped with a protective mesh from small insects. The internal controlled part allows you to set the amount and direction of fresh air movement.

The features of window ventilators include the following:

• the light zone of the double-glazed window remains free;
• lack of drafts, as from an open window;
• the flow of street air passes organically, in full;
• there will be no heat loss;
• maintaining sound insulation;
• you can set the operating parameters, especially if these are automatic systems;
• simple installation and use.

The ventilation valve looks like a narrow box, which 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 allows air flows into the apartment, and in strong winds, the feathers block the entry of cold into the room. Due to the fact that the ventilation is regulated automatically, it is not necessary to open the windows for airing in the morning and in the evening.

Classification

When choosing a supply valve, you can rely on the following criteria:

1. Release material:

• metal;
• plastic.

• mechanical adjustment, where the desired level of ventilation is manually set;
• automatic option, when the element itself determines the opening / closing period of the supply channel, depending on humidity, pressure surges in the room, the number of people in the house, etc.

• Rebate mechanism, when air flows through small holes in the shutter. It is not necessary to dismantle the window, but the throughput of the valve is low, soundproofing qualities may suffer.
• Slotted systems, where air enters the premises through a hole up to 16mm high. Outside, the system is covered with a protective block from small insects and moisture. The inner part is represented by a regulating flap. Installation is carried out on the upper vertical or horizontal crossbar.
• Overhead elements. Installation is not performed on an existing double-glazed window.
• Wall mechanism, where air exchange passes through a hole in the wall and a 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 the installation of a double-glazed window.
• Without installation.

• Russia;
• France;
• Germany.

TBK-Market consultants will help you choose window ventilation to create the ideal microclimate in your home, office or industrial premises.

When repairing any house or apartment, an important step will be the replacement of outdated wooden window structures with new plastic windows. Such a change, as a rule, makes a dramatic change in the appearance of the entire premises, that the owners of the apartments only think about why they did not do this before. 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 heat up much, maintaining an optimal microclimate inside the room.

However, due to such tightness, the apartment may be broken. In Soviet-built apartment buildings, ventilation ducts do not always cope with the increasing load, so you need to know what constitutes supply-type ventilation on plastic windows.

In most designs of modern housing stock, the simplest ventilation systems are presented, which consist of an ordinary kitchen hood or hood installed in the bathroom. The influx of air masses is provided by the slots in the window and door openings. This option is successfully used in houses in which ordinary wooden boxes are installed. In the event that a set of plastic windows is installed in such a house and door seals are installed, 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 leads to the fact that it becomes difficult to stay in the room due to strong stuffiness.
• In the rooms, there is a pronounced discomfort 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 smells 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 features. Many note that in addition to a draft-free system, they begin to experience such problems as severe fogging of glasses and stuffiness.

In the event that users have complaints about the manufacturer, then most often a recommendation is given to open the sashes, 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 acquiring plastic windows. When contacting a company that implements such structures, you need to inquire about the following features:

• Is there a vent.
• Is there a "comb". Although the cost of such a device is small, the benefits of its use are very tangible.
• Does this design have a valve for ventilation.
• Is there a possibility of self-ventilation..

Comb. Thanks to this device, you can adjust the sash in the desired position. This design has a number of differences from the usual folding mechanism and allows you to independently adjust the width of the opening of the valves in various positions.

Thanks to the use of the window, you can guarantee the normal operation of the entire. The air, getting into 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 of such a window increases significantly. At the same time, the luminous flux in the room is small, but it is also reduced.

Self-ventilated windows. For their manufacture, a special type of profile is used, which has holes in the outer and inner upper elements. This ensures that air masses enter 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 wide and more expensive profile. In this case, weak traction will not be able to provide the influx of air masses in the required volume. In the heat, the full operation of the system will be difficult, and it will not be able to work due to the peculiarities of the convection process.

Air exchange rate table

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.

To date, the following installation methods are used:

• Replacing old double-glazed windows with new ones that are smaller in size to install a ventilation valve in the vacated space.
• A valve that is located in one of the elements of the upper sash.

The first method has certain disadvantages. In particular, there is a decrease in the luminous flux, which increases the material costs for additional light sources. 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 recommended to avoid such options in which the valves cannot be adjusted. Manual control is not only more financially beneficial, but also allows you to conveniently adjust the airflow and reduce 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 difficulties often arise during operation during the cold season, since it is not always possible to predict the appearance of ice, condensate or. In order to remove certain "risk factors" it is recommended to do the following:

• Provide high thermal insulation of valves, paying special attention to the part located outside the room.
• Install a "thermal break" made of plastic if a metal case is currently used.

The valve is a fairly 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 the ventilation ducts. The advantage of slotted valves is that they are easy to install and provide normal air exchange without the need for disassembly.
• Seam dampers allow for a normal flow of fresh air, which is carried out thanks to the seam cutouts in the window blocks. Differ in low throughput and excellent indicators of sound insulation. They also have a low cost.
• Overhead valves. They have the largest air flow and have a number of serious drawbacks. For example, they cannot be installed on already installed plastic double-glazed windows, and their use worsens the performance of heat and sound insulation.

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 to install ventilated plastic windows is the "binding" method. Adjustment of double-glazed windows for ventilation is carried out both in automatic and manual mode. Automatic control allows you to achieve optimal creation and reduce the level of humidity.

Thanks to the use of valves, it is possible to achieve complete isolation from external noise sources and prevent drafts, dampness, condensation and fogging. Since mold, dampness and fungi do not have the best effect on the human body, lowering immunity and performance, it is recommended to trust the installation of ventilation of plastic windows to real professionals with extensive work experience and knowledge in their field.

Control valves do not require special care and maintenance. It is enough just once a year to clean their surface from dust and various contaminants. For the normal operation of the ventilation of plastic windows, the correct functioning of an ordinary hood is necessary. Otherwise, it is violated, and condensation may accumulate in the room and the windows may fog up.

findings

For the effective operation of all the options described above, an established ventilation system will be required. Although the above options allow you to implement a normal exchange of air in the room, there are various factors that can affect it.

They have enough advantages over wooden predecessors. But they also have some disadvantages. For example, perfect tightness saved the home from drafts, but at the same time, the microclimate changed for the worse.

A vent 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 gave rise to constant drafts. And if in the summer it pleased, then in the winter it caused inconvenience. The older generation remembers how they had to caulk cracks in the fall. But at the same time, the dwelling had an ideal microclimate, there was no stale air. For the same reason, ordinary wooden windows do not sweat, and plastic ones often “cry”, which leads to the rapid formation of mold.

Do not forget about the factors of normal life:

Drying in the apartment of washed linen;

Human breath that releases carbon dioxide

sweating;

Steam generation, heating oils during cooking, etc.

These factors can significantly harm the plastic double-glazed window. Experts recommend airing a room with such windows 1.5-2 hours a day at any time of the year.

solid virtues

According to manufacturers, the ventilation valve for a plastic window is an ideal device. It does not reduce the amount of incoming light, does not cause drafts, maintains air exchange, creates a constant supply of fresh air, while not cooling the temperature in the room and without worsening 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 causes the temperature to constantly jump.

Design features

A narrow oblong plastic part is a ventilation valve for a 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 certain mode of air exchange. There are usually two reasons: the difference in humidity and temperature in the home and on the street.

Airflow control methods

There are two types of air vent settings:

Manual. To do this, some models have a cord (like blinds), since usually the valve is located quite high. For other devices, the adjustment takes place through the engine. As a rule, its extreme left position completely opens the valve shutter, while the right one blocks the air flow. Therefore, how to close the ventilation valve on a plastic window with manual adjustment usually does not raise questions. The only disadvantage is that it is quite difficult to choose the right mode on your own.

Automatic. This option is ideal, but you will have to pay extra for it. However, the expense is justified. For example, saving heat in winter. In the absence of residents, the humidity in the room decreases, and the device reduces the flow of fresh air. The operation of automatic regulation is based on sensors that measure either indoor and outdoor humidity or pressure.

If the automatic version is based on pressure measurement, then the system works as follows. A curtain with a top suspension rises or falls depending on the air flow (wind) pressing on it. If the ventilation valve for a plastic window is equipped with a pressure sensor, which is made of nylon tapes, then the adjustment will be carried out by increasing or decreasing the cross section of the through hole. The system is simple: the more humid the air in the room, the wider the valve is open.

Valve types

There are only three types of ventilation valves on the market:

1. Slotted valves. Ensure sufficient air flow. It enters through a hole, the width of which ranges from 170 to 400 mm, and the height - from 12 to 16 mm. From the side of the street, 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 placed in the upper part of the sash or in a horizontal dividing profile. The advantages of this type of device are a large throughput and ease of attachment that does not require dismantling.
2. Folded valves. A cheap and simple ventilation valve for installed plastic windows. Seam valves supply air to the room through small narrow cutouts in the porch. The undoubted advantages are the installation, which takes place without much effort, and the preservation of sound insulation. A small minus is the low throughput, which is why folded valves are not suitable for large rooms.
3. Overhead valves. A similar ventilation valve for plastic windows (reviews from numerous customers confirm this) has the highest throughput. But the overhead option cannot be used on already installed double-glazed windows. For him, you need to prepare a place in advance.

A fairly large range of products of this type is presented in stores and markets. They differ in installation methods, air volume and other characteristics. The main disadvantage in the use of overhead valves is a significant loss of sound and heat insulation characteristics of double-glazed windows. Therefore, at home, experts do not recommend their use.

For those who do not want to spoil the design of the window, the designers offered the perfect solution. This is a vent valve handle for plastic windows. Significant advantages:

The device is designed to provide natural airflow, which is especially important in the off-season and the 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 straight-through design, so the flow of cold air entering the room does not create condensate, which allows the window not to freeze at low temperatures;

An air filter is installed in the valve, which prevents the penetration of dust into the living room. 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 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 flow of air in strong winds.

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 selected damper should be close to those of the installed double-glazed windows.

If you have to install it yourself, then it is better to choose a rebate or slotted valves.

There are no other special nuances. It remains only to compare prices, find out brands and study the quality of the goods offered.

Manufacturers

The most popular devices are Aereco, Air-Box (Comfort, Comfort-S) and Regel-Air.

Aereco models have different air jets. Both oblique and straight direction can be adjusted. They differ in great functionality. In addition to their main duties, Aereco, for example, normalizes the level of humidity in a residential area. The function of the hygrocontrol is responsible for this.

Air-Box is the leading manufacturer of ventilation valves. The devices of this manufacturer have the best efficiency parameters and are easy to install. They are also compact and relatively cheap.

Ventilation valves of a domestic manufacturer also appear on sale. For example, a line of these devices was released by Mabitek.

Installation of a ventilation valve on plastic windows

There are only two options. The first one is global. Complete glass replacement. Moreover, the new one should be slightly smaller, because a valve will appear at the junction of the frame and slopes. In addition to high costs, there is another disadvantage - the luminous flux is significantly reduced.

The second option is installation in a window frame. Work lasts no more than 30 minutes.

Step-by-step instruction

The device can be attached in the following ways:

On any sash from above;

on the frame;

At the junction of a window and a wall (only possible when installing a double-glazed window).

The easiest installation option is the following:

1. Decide where to install the valve.
2. Attach the device, then open and close the sash. The valve must not rest against the slope.
3. Having outlined the attachment points of the device, we make side cuts with a clerical knife.
4. We remove the insulation laid during the installation of the double-glazed window, and insert the mounting seal.
5. We remove the protective film from the body of the device and fasten it with self-tapping screws to the prepared place.
6. Between the fasteners we insert the additional seals that come with the kit.
7. Opposite the installed product, we cut out the old seal and insert the one attached to the valve.

Installing ventilation valves on plastic windows is not particularly difficult.

Care

The supply valve for plastic windows has some features in operation. It is strictly forbidden to wet and wash. Disassembly is also not recommended. You can use a vacuum cleaner for cleaning. In the case of general cleaning, construction or finishing work, the device must be sealed (for example, with special adhesive tape).

Clean the valve at least twice a year.

Before the winter cold, it is necessary to insulate the valve with high quality. Pay special attention to its inner part. If the body of the device is metal, then a plastic thermal break must be equipped between the outer and inner parts.

In an apartment where plastic windows are installed, there is a low level of heat loss. No noise from the street is heard. However, these products also have their drawbacks. They contribute to the stagnation of air in the apartment and the formation of condensate. This can lead to the formation of fungus and cause various respiratory diseases. The supply valve on plastic windows will solve the problem, reviews of which will allow you to choose and install the ventilation element correctly. 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 the reviews about the main disadvantages of plastic windows.

The absence of drafts, compared to wooden windows, is, on the one hand, an advantage of the presented products. However, ventilation has to be done by opening the flaps. In winter, 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 rises. This is not a healthy state of the atmosphere in the home. The supply valve for plastic windows, reviews of which will be discussed later, is able to prevent the development of fungus and mold, and remove condensate.

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 the reviews of experts and ordinary users, supply ventilation valves on plastic windows eliminate high humidity and condensation, and also maintain a healthy indoor climate.

This device has a number of advantages. The supply 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, no sounds from the street are heard. The supply of fresh air is sufficient. According to reviews, supply ventilation valves for plastic windows can be adjusted.

Another positive quality can be considered the ease of installation of this device.

Principle of operation

After reviewing the reviews of expert installers, we can conclude that the supply ventilation valve for plastic windows must be correctly installed in order to perform its functions in full.

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 along with a new seal.

Through the presented device, street air enters the apartment, and moist internal masses are pushed out through the ventilation ducts back out. The circulation process occurs due to the pressure difference.

Valve assemblies

After reading the reviews of professional installers about the supply air vent for plastic windows, you can get an idea of ​​​​its device. The product consists of several parts.

The outer side is outside the window. She takes in air from outside. A visor must be installed above the outer side, which will 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, i.e. 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 airflow adjustment mechanism.

Basic job requirements

According to experts in the field of ventilation technology, supply ventilation valves for plastic windows operate under certain conditions.

Automatic extraction occurs if the outside temperature does not exceed +5 °C. Otherwise, ventilation stops its work, therefore its implementation should be carried out by force.

The inlet reviews, which we are considering today, function correctly, provided that the ventilation in the apartment is functioning properly.

Also, the gaps under the interior doors should be at least 2 cm. The front door should be hermetically sealed.

Valve types

According to consumer reviews, there are a great many models of supply valves for plastic windows. According to 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 on their own when to open or close the vent. Moreover, the settings can be set based on indicators of 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. That is why most consumer reviews tend to choose automatic supply valves for plastic windows.

Air intake

According to the way air enters the room, there are folded, slotted and overhead valves for supply ventilation on plastic windows. Reviews of people who have tried the presented devices in their premises indicate the following.

One of the most economical options are rebate supply valves. Cold air in this case enters through small cutouts in the porch. Windows can not be dismantled. However, such designs are quite low.

Higher throughput, according to consumer reviews, has slotted supply ventilation valves on plastic windows. They are also installed without dismantling windows.

However, air is best passed overhead devices. 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 valve handle is a very convenient device. It is installed instead of an ordinary window handle. Of the advantages of this device, it should be noted that there are no changes in the appearance of the window.

These are quite interesting supply valves for plastic windows. User reviews assure that the ventilation valve in this case can be located where condensate most often collects on the window.

This is a very effective device for removing moisture. Such a valve does not freeze through, as it has a direct-flow design. Also, the handle valve has a built-in filter that does not let dust into the room.

Valve selection

Among the many options for models on the market for such ventilation equipment, you can get lost.

Manufacturers with a good history that have long existed on the supply valve market are more popular. These are conscientious companies that have confirmed the quality of their products through 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 save on quality. It should also be understood 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 the external elements of many structures freeze, and there is a constant supply of cold air.

A distinctive feature of metal-plastic windows is the ability to retain heat in a residential building. They effectively prevent the penetration of sound, cold, moisture. At the same time, these solutions do not allow to provide the interior space with fresh air in sufficient volume. The only right decision is to install a supply valve on plastic windows. What are these products, and what is their purpose?

Are air conditioners needed at all?

Plastic windows have a lot of obvious advantages. They were appreciated not only by the owners of city apartments, but also by country cottages. That's just for all their "pluses" visually beautiful solutions de facto worsen the microclimate of housing. Installation of supply valves on PVC windows is the most affordable and easiest way to normalize the temperature and humidity conditions, leveling the risk of mold and fungus.

So what is this device and how does it work? The supply valve for plastic windows is a small solution that is usually installed in the upper sash of the frame. It is located in a strictly horizontal position, due to which the exhaust function is realized. A small valve not only eliminates the likelihood of condensation in the frame, but also helps maintain a comfortable microclimate.

It is advisable to use inlet valves on windows for a number of reasons:

• in the process of its operation, any heat losses are excluded, the level of sound insulation is maintained at the original level;
• unlike traditional ventilation, there are no drafts;
• the window opening does not change in any way in terms of light penetration;
• the product can be easily installed, no problems arise during operation;
• The operation of the device can be adjusted at your own discretion.

Why are intake valves needed?

Design features and nuances of functioning

Proper installation of the supply valve on a plastic window is possible only if there is an exhaustive understanding of the mechanism of operation of this device. In the process of installation work, a section with a rubber seal is removed from the structure of the window opening, moreover, both at the sash and at the frame. It is replaced with an additional layer of sealant and a supply device, to which the role of passive ventilation is delegated.

Solutions installed in this way allow warm air to be removed outside and fresh oxygen to be taken into the room. This is achieved due to the pressure difference. The system works provided that the temperature outside the window is not lower than +5°С. Ventilation products in the sultry heat are driven by forced exhaust.

The valve on the plastic window includes a number of elements:

• external air intake structure(only mounted on the outside of the frame). Above the product itself, there must certainly be a visor that prevents moisture and atmospheric residues from penetrating inside;
• compact telescopic channel- a small element, combined with the window body and fixed with a special sleeve;
• inner fragment located inside the room. From a structural point of view, this is one of the most complex elements of the system, which includes: a control mechanism (for adjusting the air flow), a filter grill and an outlet nozzle.

Construction device

There are a number of conditions necessary for effective work in plastic windows:

• functioning of the main house ventilation duct;
• the presence of natural air exchange (small gaps in the floor, in interior doors);
• tightness of the entrance door;
• outside the window the temperature regime is not lower than + 5 ° С.

Be sure to watch the video on the principle of operation of the supply device.

The program "Miracle of Technology" on NTV, about the supply valves Aereco (Aereco)

A wide range of exhaust solutions for PVC windows is on sale. As for the differences between specific models, they are usually considered according to a number of criteria.

Varieties of supply devices

Depending on the predominant design material:

• metal;
• wooden;
• plastic.

Fresh air intake method inside the room:

• Overhead Solutions. Ventilation valve for plastic windows characterized by high efficiency. Its key feature is the need to "adjust" the design of the frame and the double-glazed window to the exhaust device. Such products cannot be built into a finished window. The main scope of application is warehouse facilities, industrial complexes.

• Supply and slot structures. Air is taken in through a 16 cm slot. Inside the room there is a special control block, and outside there is an inlet that prevents the penetration of insects, small particles and precipitation. For installation, there is no need to dismantle the window. The product has a fairly high performance.

• Seam products. One of the most affordable varieties of window. The supply of fresh oxygen is carried out through small cutouts located in the porch. The solutions are distinguished by good sound insulation, low throughput and ease of installation.

By type of management:

• manual;
• automatic.

note! Original designs in the form of a handle valve are in great demand. This product replaces the traditional window handle and at the same time does not violate the appearance of the opening itself.

Step-by-step instructions for installing a vent valve

Let us dwell in more detail on the nuances of installing a valve with your own hands. This event does not require any specialized skills, and in time the whole process lasts up to 40-60 minutes.

To install the supply valve on the windows with your own hands, you should prepare:

• sample;
• screwdriver of medium length;
• complete valve;
• stationery knife.

All of the listed elements necessary for the installation of small products are included in the standard delivery set. The length of the valve does not exceed 35 cm. In addition to it, you will need 2 seals, each of which is at least 16 cm long, as well as an additional length of 35 cm. Special fasteners on self-tapping screws are used to fix the structure.

Stage 1 . Localization of the installation site. Window inlet valves are usually placed in the upper part of the sash. Experts recommend marking a place in the middle of the structure, and then attaching a template to it and circling it around.

Stage 2 . Seal recess. In the designated area, the standard seal must be removed. It is not fixed too tightly and if you make small cuts with a clerical knife, then the rubber product can be completely removed.

Stage 3 . Installation of fixing dowels. It is necessary to insert 3 fixing dowels into the free groove. Their main purpose is to fasten the valve body to the base of the leaf. One dowel is shifted exactly in the middle, and the remaining 2 are placed at the edges.

Stage 4 . Installing a ventilation device on a window. To make it more convenient to work, we recommend that you first apply double-sided mounting tape to the surface of the sash. The valve is located in the most preferred position.

Stage 5 . Fixing the valve on the window sash. The ventilation product must be attached to the profile structure using self-tapping screws (do not forget about dowels). This will allow you to securely fix the product.

Stage 7 . Removing the old frame seal. In order for the ventilation device to function properly, it needs to provide a supply of clean air. To this end, experts strongly recommend abandoning the standard seal, replacing it with the one that comes with the valve. Opposite the fixed valve, a segment is marked, the total length of which should be at least 35 cm. We dismantle the old seal and then replace it with a new one.

The seal in the frame has the form shown in the image below. If we take a narrower seal, then a small gap will form between the leaf and the base of the frame, through which fresh oxygen is taken. The window will remain functional.

This completes the installation process. At your own discretion, you can adjust the flow of oxygen using a small slider. In the right position, the shutter will be fully open, therefore, the air flow will be maximum.

The device discussed in our article is a useful and necessary solution for every home, which allows you to significantly improve the microclimate of your home. Installation work, if desired, can be done with your own hands, without resorting to the help of specialists. Installation features depend on the configuration, design and specific valve model.
