Installation of the vent valve. Advantages of using a supply valve. REHAU Climamat Ventilation Valve

Often, the installation of hermetic window structures entails a deterioration of the microclimate of the room: humidity rises, there is a lack of oxygen and airiness. Problems can easily be solved by placing the supply valve on the plastic windows - the device normalizes natural ventilation and stabilizes the air exchange. Consider how to choose the right ventilator and carry out its own installation.

The basis of a normal microclimate of a premise - presence effective system  ventilation.

The air must constantly circulate - contaminated with an excess of carbon dioxide is removed through the hoods, and clean comes from the outside.

The normal air speed in a residential house or apartment is 0.15 m / s. A significant increase in the index provokes a draft, and a decrease will stop air exchange

When designing Soviet-built buildings special attention  were given to the exhaust ducts, and the supply air ducts were not equipped. The arrival of fresh air took place naturally - through the cracks in the window wooden frames.

Old imperfect structures effectively coped with the task, ensuring sufficient airflow even in winter. Lack of wooden frames - poor noise and heat insulation

Metalloplastikovye analogues are equipped with air chambers in sashes and frames, hermetic double-glazed windows and seals around the perimeter. Modern constructions  isolate the room from street noise and keep the heat, but paralyze the normal functioning of the ventilation. As a result, the microclimate deteriorates - the air becomes stale, the humidity rises, people experience a lack of oxygen.

Infringement of air exchange negatively influences health and ability to live of people. Condensation appears on the windows, slopes and walls are covered with mildew - the concentration of toxic substances rises

The attempt to restore air circulation by opening the window in the ventilation mode can not be considered a successful solution for the following reasons:

• the advantages of "plastic" are reduced to zero - the efficiency of the thermal insulation of the room is reduced;
• the ventilation works only when the window is open, which is especially problematic to organize in the cold season or in windy weather;
• the influx of air is uneven and uncontrolled - drafts appear.

Some manufacturers of window systems took into account the consequences of complete tightness and improved metal-plastic constructions. Special vent accessories:

• ventilated profiles;
• opening limiters;
• partially airtight seals;
• shtapiki with a control valve.

To ensure the flow of air through the previously installed window, a supply valve is used.

Due to the ventilation valve, the air exchange in the room is carried out without loss of heat. The device protects the room from penetration of noise and dust (+)

The operating principle of the window valve

In fact, the supply valve is a slot with flaps in the window structure. The ventilator is part of the natural air exchange. The device operates due to the difference between the pressures inside and outside the room. For the effective functioning of the "feeder", an exhaust ventilation is necessary.

In the hot season, to ensure the circulation of air flow, it will be necessary to include forced ventilation. Extraction will accelerate the influx of fresh air

Standard equipment for a vent valve for plastic windows:

1. Air Intake – outside part  device, mounted from the outside of the frame. The intake unit has an insect screen and a visor that prevents snow and rain.
2. Through slot  - the telescopic channel through which the air flow passes. The element cuts into the window frame.
3. Inside  - installed from inside the room. The exhaust unit is equipped with an injector, a flow control valve and a filter.

Street air enters the air intake opening, moves through the telescopic channel and exits through the nozzles. Then, under the action of the convective flow from the radiator, the air rushes to the ceiling and warms up.

Heated air descends into the residential area at some distance from the window, maintaining a comfortable temperature regime  indoors

Which air intake device to choose

To select optimal model  ventilator for installation on plastic windows it is necessary to determine the method of its installation and the type of adjustment. The quality of the device largely depends on the manufacturer's company, and the efficiency of the operation from the technical characteristics of the device.

Types of ventilators by type of construction

Supply valves for PVC windows according to their design features are divided into three main groups:

• folded;
• slotted;
• invoices.

Folded models. Micro-ventilation of the premises is carried out by means of a slot in the frame. The window can be equipped with such a device without dismounting the double-glazed windows.

Advantages of folded valves:

• affordable cost;
• preservation of heat and sound insulation properties of the window;
• simplicity and speed of installation;
• the possibility of automation.

Minus - low throughput (up to 5 m3 / h). To increase the airflow, experts recommend installing two valves per window.

Folded "pritecniki" are often equipped with humidity sensors. Preference should be given to models where the sensor-drive is removed from ventilation duct  - this ensures accurate valve operation

Slot climatic devices. Fresh air comes through a gap, the width of which is 17-40 cm, and the height - 12-16 mm. The valve has an inlet and a regulating unit. Advanced models consist of one universal box.

Advantages of slotted models:

• sufficient capacity (about 20 m3 / h);
• protection from external factors;
• the possibility of installation without removing the double-glazed windows.

The disadvantage is the difficulty of installing two-block models that require a window block milling. This disadvantage is deprived of cheaper analogs. Simple "supplyers" ensure the flow of air through the space between the sash and the frame.

For installation of the simplest ventilator it is enough to remove a part of the regular sealant on the frame and place the valve according to the manufacturer's instructions

Overhead valves are similar in principle to slit models. The main advantage of the device is high performance (up to 100 m3 / h). "Pritotniki" are located in both deaf and open windows. However, the installation takes place before the installation of the double-glazed unit.

Devices of a waybill type are usually used in production and office premises, installation in a house or apartment is inexpedient. In addition, such valves allow street noise and deteriorate the thermal insulation of the window.

Methods of controlling the window "outpost"

Dependent on the valve device for plastic windows, the intensity air supply ventilation  can be constant or adjustable. The optimal parameters of the microclimate will be achieved with a ventilator with the possibility of regulation, which can be automatic or manual.

The operation of an automatic valve is based on one of the principles:

1. Stabilization of air supply due to the pressure difference between the room and the street. The owner sets the permissible range of airflow that is supported by the device under different atmospheric conditions.
2. Adjusting the air circulation with a polyamide sensor. The valve cross-section increases with excess moisture, and when the optimum microclimate is reached, it decreases.

Minus automatic devices - high cost. In addition, in certain models it is not possible to completely block airing.

The principle of the physical law is based on the work of a hygro-regulated drive: with decreasing humidity, matter narrows, and when it increases, it lengthens

Adjustment of the air flow in the mechanical device is due to a change in the position of the gate or shutter. The manual way of setting allows you to choose the time for airing the room. This method is more rude - unconsciously, the person himself, can allow the occurrence of drafts and hypothermia of the room.

Selection of the main characteristics of the valve

When choosing a vent valve, special attention should be paid to the following parameters:

№1.   Performance range. The value of the indicator depends on the pressure drop at the outlet and the inlet, as well as on the cross-section of the "sub-source".

When evaluating models, it must be taken into account that in technical characteristics  The capacity is always indicated with reference to the pressure difference. It is not necessary that the device with a capacity of 15 cu. m / h at 10 Pa will flow a larger airflow than the equivalent with an index of 12 m3 / h at 5 Pa.

Normal air exchange in the room is provided by valves with a throughput of 20-35 m3 / h at a static pressure of 10 Pa

№2.   Provision of noise insulation. Most of the metal-plastic windows have a sound insulation index of 30-35 dB. The supply unit must correspond to such characteristics that after installation of the valve the noise level in the room remains the same.

№3.   Operating temperature. Through the ventilation device, water vapor outwards. In the winter it is fraught with complete icing and equipment failure. AT modern systems  The principle of "thermal rupture" is used - between the metallic inner and outside  there is a plastic insert.

№4.   Possibility of adjustment. For living quarters, it is not desirable to select devices without the possibility of air exchange control. There is a constant need to change the intensity or completely shut off the ventilation duct.

Overview of popular ventilator models

There are a lot of models of ventilation valves on the market from different manufacturers. As in every industry, there are leaders here: Aereco, Air-Box, Helios, Vents and Siegenia.

Valves of Aereco EHA2 series, as well as products of the manufacturer Helios with the letter designation "S" are characterized by increased sound insulation (+)

Aereco (France) offers various modifications of ventilators. Automatic valves are equipped with a V8 sensor and operate on the principle of hygro-regulation. The sensor drive is located away from the air flow.

Aereco ventilation valves for plastic windows are available in several colors: white, teak, beech and gray. Separately, you can buy visors for better acoustic protection

Popular Aereco models:

• ENA2  - Available in three variations of different performance. The material of production is plastic, the maximum capacity of the model line is 35 cubic meters. m / h, sound insulation - 37 dB.
• EMM  - The main difference from previous products is the mobile outdoor unit.
• EMF  - Absence of a system of hygro-regulation. The model is equipped with a manual mode switch.

Air-Box (Russia) produces plastic "brushes" of manual regulation. The main advantage of the models is the ease of installation, the lack - the lack of automatic control over the level of humidity.

There are no outdoor units in the standard version of the Air-Box valves. A narrow plastic casing is installed only from inside the room to the sash of the frame

Air-Box Series:

• Standart  - the valve is mounted without milling. The main purpose of the valve is to prevent condensation on the PVC windows. The volume of incoming air is 4.8 m3 / h with a pressure difference of 10 Pa, noise insulation is 32 dB.
• Comfort  - Two ways of installation are possible. The insertion of the vent into the frame increases its capacity from 31 to 42 m3 / h. The infeeder can be used in any swivel and swivel-folding structures.
• Comfort S  - is mounted only on profrezereirovannye apertures. A special feature of the model is the two-way direction of the air flow, which ensures a better airing of the room. The capacity of the valve is 40-42 m3 / h.

Renson (Belgium) produces supply ventilation of the slot type Aerovent. The valve is equipped with a filter and mosquito net. Manual control by means of a cord is provided - operation is carried out in two modes: "closed" and "open up".

The main characteristics of Renson Aerovent: body material - aluminum, air flow - 21 m3 / h at 10 Pa, sound insulation - 33-42 dB

Mounting of a ventilator with perforation

The valve for perforation is preferably mounted at the top of the window. The complexity of the work lies in the need for milling the frame - here you can not do without special equipment and skills in working with power tools.

Nuances of installation of the built in valve

When planning a valve insertion, it is necessary to take into account some points:

• installation of the ventilating device is better performed on the removed leaf;
• installation is carried out in the warm season;
• when cutting the hole, it is necessary to work neatly, so as not to damage the seal on the leaf.

The leaf is removed from the hinges, installed in an inclined or upright position.

From the frame part of the fittings (scissors and angular gear) is removed, the counter strips are removed - they can prevent the milling

List of necessary tools

For the installation of an "outpost" you will need:

• electric drill and drills (diameter - 5 mm and 10 mm);
• fine-grained file;
• electric jigsaw;
• template for marking holes;
• silicone sealant.

Prepare a groove will be and without a template, but it's easier to work with. You can make a template yourself from plywood or hardboard.

Step-by-step progress of work

The entire installation process supply air valve  is divided into several stages:

Step 1.  Markup. On the vertical protrusion, put on the template and mark the place of insertion of the device.

Step 2.  Milling the sash. Drill a large diameter drill a few holes in a row and connect them with a jig saw. Repeat the operations on the floating frame.

The window chambers opened during the milling process must be filled with a sealant to prevent moisture from entering and whistling during air circulation

Step 3.  Mounting the mounting plate and valve. The back of the strip is treated with a sealant, attach the part to the leaf and fix it with screws.

The inner unit of the air handling unit should be mounted to the frame and snap the fasteners on the bracket. Check the smoothness and tightness of the valve

Step 4.  Mounting the visor. From the outside of the frame, secure the protective cap with screws. The joint between the parts should be treated with a sealant. At installation it is desirable to use the insurance.

Step 5.  Completion of installation. Fittings should be installed back into place and the sash must be hung on the hinges. Set the ventilation mode on the ventilating device.

Mounting the valve without milling

The installation of fresh air ventilation without punching the door takes a little time and does not require special skills. From the tools you need:

• stationery knife;
• screwdriver or screwdriver;
• ruler.

The required valve components are supplied complete with a "supply unit". Standard set includes:

• valve;
• one long and two short gaskets;
• stubs for fixing the device;
• self-tapping screws.

First you need to determine the location of the valve and mark it with a pencil. Optimum - install the device in the center of the leaf.

If the leaf is too narrow, then the "tributary" should be moved slightly to the side, so that the valve does not block the window hardware

In the marked points, with a sharp knife, make incisions and take out the sealant from the groove.

To install the valve in the open groove place the fixing dowels - one in the middle and two on the edges. Remove the protective film from the adhesive tape and attach the device in the desired position.

The valve is attached to the profile by screws, which are screwed into the installed dowels through the holes of the "sub-source". Instead of a standard seal, install small seals in the kit

On the frame, too, you need to replace the seal with a narrower one so that the valve can flow through the air flow. The changes made will not affect the efficiency of the casement.

At the end of the installation, it is necessary to adjust the valve, changing the position of the engine. The right position - the greatest air flow, the left - the closure of the gap

Video on how to install a ventilator

Video materials will help to better understand the technology of installing different types of ventilation valves.

The order of mounting the slotted valve without milling the window frame:

The technology of tapping the inlet valve:

Ventilation valves do not replace air conditioning systems, which refresh and change the room temperature. At the same time, "pritecniki" is an excellent alternative to open leaflets and leaflets. The installation of the valve is possible under any home master.

The appearance of plastic windows saved the inhabitants of the city from noise and smog, but deprived them of the opportunity to breathe fresh air. The average adult consumes up to 30 to 60 cubic meters of air per hour, children from 15 to 30. After 8 hours of sleep in a standard unventilated room (20 square meters), the level of carbon dioxide doubles, which leads to a lack of sleep, headache and a bad mood in the morning. Solve the problem helped engineers who developed a special valve for natural ventilation of premises.

The idea of ​​air intake valves appeared in the 1970s and 1980s in the Western countries. Then, within the framework of a reduction in energy consumption, residential projects that did not have natural ventilation began to be introduced. The rapid accumulation of carbon dioxide made new buildings absolutely unsuitable for life.

The massive installation of plastic windows in the post-Soviet space again raised the problem of natural air exchange. It would seem that the window is easy to open for airing, but along with the harmful carbon dioxide  The room is pleasantly warm, especially in winter. If earlier from the cooling out only the private houses with individual heating, then the new policy of energy-efficient consumption periodically makes even the townspeople sit in fur coats.

Solve the problem of musty air in one day. The inlet ventilation valve for plastic windows is easy to install without the need to dismantle the window frame.

Advantages of inlet valves

In addition to the main function - air ventilation in the room, the supply valves have a number of additional advantages. Thanks to natural ventilation, excessive moisture does not accumulate, and the likelihood of mold and fungus is also reduced. It is especially important to monitor the ventilation in the bathroom, the kitchen and the balcony, because it is in them that the risk of black mold - a fungus that causes aspergillosis - is great.

In summer on hot days with a closed window the air in the room is heated in minutes. Close or not close the window when leaving home - it becomes a real dilemma. However, an open window can cause illegal penetration. Therefore, the ventilation valve is the insurance of your life and property.

Types of inlet valves

Supply valves by type of mechanism can be divided into slit, overhead and folded type. The first and the last do not require the dismantling of the metal-plastic structure. Overhead valves are installed before the installation of the metal-plastic structure.

The ventilation mode for each supply valve can be automatic or mechanical. Let us consider each species in more detail.

Supply valves of slot type

The inlet ventilation valve of the slit type is the most convenient, optimal and easy to install. The flow capacity of the supply valve allows for a natural air exchange without additional ventilation of the room.

The valve is a slot about the size of about 12-16 mm, which is created using the built-in channel. The channel is connected by external and internal structural blocks. The first serves as protection from precipitation and insects, the second regulates the supply of air.

Inlet valves of rebated type

The main advantage of folded valves is the absence of loss of noise insulation. Installation of valves will require more effort, but the work can be done without dismantling. Many people consider insufficient air exchange to be the only drawback of folding valves. The windows will not fog, but the room from time to time will have to be ventilated.

Overhead supply air valves

Overhead valves suitable for ventilation production facilities, since they are able to provide the greatest in comparison with all the rest of the inflow of air. The installation of overhead supply valves requires the dismantling of the window frame. Due to the large loss of heat and noise insulation, it is not recommended to use a patch type of premises in which people permanently reside or work.

Installation of a slotted inlet valve

It is quite easy to install a slit type valve. It will take the valve itself, the clerical knife and the Phillips screwdriver. First, you need to carefully remove the sealant layer from the casement wedge design with a knife in the place where the valve will be located. To make the hole look neat, you need to attach the valve to the leaf and make the markings.

After removing the sealant, it is necessary to secure the three anchors in the holes of the frame at the location of the intended installation of the valve, so that two of them are located at the edges and one in the middle. Then a protective film is removed from the valve. The device is attached to the inserted dowels using self-tapping screws.

In the set with the supply valve lie heaters, which need to be installed after the installation of the main structure. At the final stage, part of the staff heater directly on the frame is changed to a heater from the kit.

The entire installation process takes from 20 to 30 minutes. After installation, the slit valve can be used immediately.

Manufacturers of ventilation valves

Companies that produce supply valves are quite numerous on the market. As in other industries, there are both their leaders and their outsiders. The valve of any company has advantages and disadvantages.

The market leader at the moment is a French firm Aereco, producing inlet valves. Valves Aereco have high air exchange rates, low probability of icing and self-regulation of air flow. The disadvantages of the mechanism include the need for milling the ventilation duct, the lack of mechanical regulation and high cost.

The domestic manufacturer produces a high-quality valve Airboxcomfort. Airboxcomfort air inlet valves are easy to install and have the ability to mechanically regulate airflow. However, the valve can not be installed on a single leaf.

German company Siegenia  developed a more technological series AEROMAT. Supply air valves AEROMAT have the highest values ​​of air exchange and noise insulation. The loss of heat is reduced to a minimum. The only drawback of the supply valves AEROMAT - a high price.

If the tightness of the room is a priority criterion for choosing a ventilation valve, it is worth paying attention to the line of Climamat Swiss company Rehau. Supply valves Climamat are equipped with a special membrane, the throughput of which depends on the difference in pressure inside and outside.

Requirements for supply valves

The choice of valves should be based on knowledge of the basic characteristics of the model and its suitability for the claimed requirements. Otherwise, the installation of the valve will not justify expectations, but will also cause irreparable harm. Consider the main criteria for choosing a valve for an apartment building.

1. Presence of adjustment

The possibility of mechanical air adjustment should be the main criterion when choosing a supply valve. Devices with automatic adjustment can not always adequately adjust to sudden temperature changes. If in the summer the valve can be opened completely, then in the winter, an air exchange adjustment will be required in any case.

2. Level of air exchange

The indicator of the level of air exchange should be at least 30 cubic meters per hour per person. Consider other options does not make sense.

3. Loss of noise insulation

The normal noise level varies between 30-35 dB. The capacity of a plastic window with an installed supply valve should not exceed this level.

4. Valve operation in the cold season

The selected supply air valve must perform its function qualitatively with the onset of cold weather, because, if the requirement does not meet the requirements, icing of the structure and failure can occur. The material from which the valve is made must withstand the temperature changes.

5. Features of installation of the valve of ventilation

It is important to choose the type of supply valve, which does not require the dismantling of the metal-plastic structure. Valves slotted and rebated type is easy to install yourself. Before buying, make sure that the selected valve is mounted on the installed plastic window.

Questions and answers about ventilation valves

Question:  Why do we need supply valves, if in modern plastic windows there is already a function of microventilating?

Answer:   Ventilating the room using a slightly open window in the winter leads to a large heat loss. The valve serves as a barrier to the cold air path, resulting in no cooling.

Question:  Is it true that in the winter time the condensate will constantly accumulate on the valve?

Answer:   If the natural extract to the room for some reason does not work, condensation can form. Therefore, before installing the valve, you need to check the ventilation capabilities of the room. In a city apartment it is necessary to inspect the internal ventilation shaft for possible obstructions and overlaps when replanning an apartment from neighbors. To check ventilation, it is enough to open the window and bring a candle flame or a sheet of paper to the ventilation grate. If the flame or sheet begins to attract to the mine, ventilation in the apartment works well, and you can safely put a ventilator. For high-quality ventilation of the room, the doors in the kitchen and bathroom should not reach the floor 2-2.5 cm.
Country houses, as a rule, are constructed taking into account the natural and forced ventilation, so the supply valve can be installed without fear.

Question:  Is it true that after installation of the supply valve in the room, the noise level will increase?

Answer:   The noise level will increase only in case of installation of a supply air valve of the overhead type. Therefore, they are not recommended for installation in living quarters. The other types of valves have minimal characteristics of loss of sound insulation, since they are equipped with regulating devices. If desired, the valve can be completely closed - the tightness of the window will be restored.

Question:  How difficult is it to install the valve and can it be done by yourself?

Answer:   Virtually all kinds of ventilation valves are easy to install. The only exception is the intake air valves of the overhead type, since installation of this type requires special skills.

The choice of the supply air valve must depend on the purpose of the installation. For a residential house, there is enough slit and rebated valve. It is recommended to equip an industrial premise with an overhead valve. The installation of the ventilation valve will help improve air exchange with the street, reduce the noise level compared to the open window and prevent the appearance of fungus and mold.

Installation window Valves  Aereco

At installation of modern hermetic plastic eurowindows, with double-glazed windows and 2-3 seals, the influx of outside fresh air is excluded, the balance between the extract and the inflow of air is disturbed in the room. The natural system air supply ventilationstops working. There is a feeling of closed space. As a result, we get an increased level of humidity, the dew point on the double-glazed window, condensate on the windows and slopes, stuffiness and discomfort in the room. A non-functioning natural ventilation system leads to an increase in the content of harmful impurities in the air. In humans, because of prolonged stay in unventilated rooms, immunity decreases, various diseases such as bronchitis, bronchial asthma, runny nose, allergies, migraine occur, cardiovascular system disorders occur.

To solve the problems of natural ventilation of premises, to eliminate the negative consequences of the tightness of windows and the round-the-clock maintenance of the microclimate in the rooms, valves are installed on the windows air supply ventilation. They are important elements in rooms with high humidity. When installing them, the fogging of windows and the formation of damp spots cease. Activation is in progress natural circulation  fresh air.

Inflow window valves  Installed in the upper part of the window unit, where fresh air comes in, without increasing noise in the premises and the formation of drafts. The valves are mounted on the frame of the window unit. To do this, drill or milling holes.

Simple installation is easy to implement in the process of manufacturing the unit or on the already assembled units without dismantling the insulating glass.

Two methods of installing valves are used: with milling and without milling the elements of the window unit.

Mounting without milling, in turn, depends on the design of the profile of the window unit and is divided into two types:

- profile with increased noise protection;

- profile with increased air permeability.

In both cases, 400 mm of the seal of the outer contour is removed. In the first case, the removal is carried out at the bottom of the unit, in the second - at the top, opposite the place of installation of the valve.

Window Valves  complete with different types of control mechanisms (manually, rod, cord, and sometimes the electric motor). Basically, they work in three modes: "open", "closed" and "automatic", but they never close completely. In the mode "open"  - the maximum air intake is realized, in accordance with the volume specified in the manufacturer's technical passport (usually from 35 to 50 m3 / h). In the mode "Covered"  the minimum air intake from 5 m3 / h is realized. "Auto"  mode provides for regulating the air intake, depending on the relative humidity level of the air, inside the room.

Bundles of tapes made of polyamide fabric serve as special sensors that control the relative humidity level. With a decrease or increase in humidity, the fabric, respectively, is compressed or expanded, and activates the shutter mechanism vent valve.

Magic window valve or victory over the mold!

Supply air window valve  - a small detail on the windows, but incredibly important!

And that's why!

More recently, the technology of manufacturing and installation of plastic windows has penetrated to us from the avant-garde West. Today, few people refuse to install such a wonderful thing. Because in addition to the fact that any apartment is simply transformed, thanks to this element of the interior, plastic windows also have a number of practical advantages. This is an excellent protection against noise, dust, drafts.

There is no point in singing ode to the windows. All their charms are so obvious, otherwise they would not have won the market of all Russia in such a short time.

But is it all so perfect and good in the operation of plastic windows? Practically yes, but with one small condition: the windows must be attached the ventilating valve.

Why is it so important?

The fact is that this small part performs a very important function, without which the life of people in the room where plastic windows are installed, not equipped inlet valves for windowsis exposed to serious danger, to underestimate which is the upper hand of frivolity. Plastic windows, which have remarkable qualities of airtightness that so well protect against the external influences of noise and dust, become at the same time an exceptionally serious causal for the appearance in the house of black mold, capable of slowly but surely killing all living things. Of course, not the plastic windows themselves contribute to this, but the lack of ventilation in the house, the accumulation of condensate, excessive humidity, due to which the molds begin to multiply joyfully and actively.

Terrible mold

Mold- the oldest organism on Earth. It is much older than man and very well adapted to life in the most incredible conditions. For example, it is known that: the famous Mir station, being in space, began to become covered from within with mold, which grew on an incredible scale and became the cause of many malfunctions at the station. Even the on-board computer failed. The fact that all the air in the station was soaked with mold spores so that the smell of dampness and fungi was spoken by the American astronaut Michael Fole. There is a high probability that it was the mold that destroyed the station, which as a result had to be drowned. Because there is an opinion of reputable experts that "Peace" could still serve people. This fungus poses a serious threat to human health and life. Here are just some of the diseases caused by mold: causeless rhinitis, otitis media, bronchitis, cardiovascular diseases, bronchial asthma, mycotoxicosis, internal organ damage. And all this arises and develops only because people do not know - their premises are not sufficiently ventilated. They live and are sick. And then they die. If the fungus affects the walls of the house with extensive, visually visible colonies, this is already a stage when it is extremely difficult to do something. Even in the oldest document on Earth in the Bible it was written that mold can not be destroyed. And people were recommended at home, affected by mold, to leave. But do not throw them, and burn necessarily. Because the mold is able to move from the affected house to the neighboring, and to hit them too.

Today there are some ways that are used in the fight against mold, but there are not really high-performance ones. Therefore, the best way to combat this ancient misfortune, which once caused whole epidemics of various diseases in humans - prevention. Here, and come to the rescue of a small modest window valve, capable of performing real miracles! He will imperceptibly, unobtrusively and conscientiously carry out his work, contributing to the constant ventilation in the dwelling, and at the same time he will retain behind his plastic window his best functions, for which we appreciate them so much: noise insulation, heat saving and others.

Supply air window valves  for you to install our experts, inviting which you take care not only about your comfort, but also about your health! Live beautifully and stay healthy!

Plastic windows have solved many problems with energy conservation: unlike wooden frames, in which gaps inevitably form, they provide almost complete heat and noise protection.

However, this has a disadvantage: tightly fitting frames and embedded slots create problems with natural ventilation, so the room does not receive fresh air. The ventilating valve on the PVC windows will help to solve the problem: it allows to supply oxygen and at the same time the heat practically does not go to the street.

Installation Advantages

Conventional plastic windows with proper installation  completely isolate the room from the outdoor environment. This prevents water vapor from leaving the room, and fresh air does not enter it.

Standard ventilation systems were installed in the calculation for wooden window blocks, so without a natural airflow, they are useless.

As a result, mold stains appear on the walls and on the slopes over time, due to increased dampness, fungus formation is possible. People living in such a house are experiencing a deterioration in their well-being and various health problems.

Supply valves are able to completely solve the problem, they have the following advantages:

• Do not constantly open the sash for ventilation. Even with the installation of a special "comb" fixing the frame, the slit will be too large, and the heat will quickly leave the street. In the winter it creates huge inconveniences and increases the risk of colds.
• The installation creates a normal microclimate: the room will have an easy and comfortable atmosphere, favorable for health.
• The installation of air-handling devices increases the level of house security: this is an additional protection against foreign penetration through open doors.

The windows with ventilation valves last longer, as they are less likely to use fittings, and moving parts wear out more slowly and later fail. With all these advantages, their installation is inexpensive and allows one to solve several problems at once.

Due to the optimal climate, the wall and ceiling coverings, as well as the slopes will last longer, and the repair of the premises can be carried out less often.

Types and varieties

The ventilation of the premises with installed plastic double-glazed windows is created due to the use of valves of several common types:

The choice of the type of device depends on the financial possibilities, and on the type of the installed window structure. There are several popular brands that are maximally adapted to common window systems, most of them do not require serious intervention in the glass unit, so installation will not take much time and will not entail large financial costs.

Criterias of choice

The choice of a vent valve is a critical task: the microclimate in the house and the health status of the tenants depend on its performance. Professionals advise paying attention to several important parameters:

Important! In residential premises, it is not necessary to install devices in which there is no possibility of regulation at all. The need to change the intensity of ventilation or completely block it arises constantly, so the valve will still have to close something, and this will create unnecessary inconvenience.

Inquiry marks

About plastic windows with a vent valve you can read a variety of reviews: some users praise them, some, on the contrary, are sharply criticized. However, this depends not so much on the fact of installation itself as on the type of supply system chosen. Let's consider more in detail the most known offers of manufacturers.

Aereco

This is a French version of supply ventilation with the possibility automatic adjustment. It is carried out with the help of special plates of polyamide: they begin to expand with increasing temperature, this drives the unit opening the valve. The design is mounted in the window unit, in addition, it can be installed directly into the wall above the window opening.

The system with automatic control  allows to solve a problem of a cold in a premise: the gauge itself reacts to temperature change, and the heat simply can not leave outside. At the same time, this device does not require the installation of complex air ducts, it does not need additional power supply, it works noiselessly. This is one of the most profitable solutions, so it has gained wide popularity.

Air-Box

To install soundproof windows with ventilation valves, it is not necessary to spend on imported products: in the market you can find a widely used, very effective domestic development. The device consists of two parts - external and internal. The first takes cold air from the street, the second provides its supply to the room and efficient ventilation.

The Air-Box valve requires a working ventilation system  in the building: the petals open on the principle of depletion due to pressure fluctuations. The intensity of air exchange reaches 6 cubic meters of air per hour. You can buy it as standard option, and the device series Comfort.

The first requires milling of the window unit, the second one can be mounted independently. To do this, only remove the seal. The device can be adjusted in manual mode, which makes it possible to block the influx of outdoor air at low temperatures in the street.

Self-installing

To put an Air-Box device on your own, you only need a knife and a cross-head screwdriver. You do not need to invite specialists for this work. The valve is normally installed on top  window frame, while it should be placed in such a way that the door does not touch it when opening and closing.

The work is carried out as follows:

• The device is applied to the leaf, it needs to be marked. If there is no possibility to put it on the top of the window unit, it can be placed on the side, but it should be as high as possible.
• After marking, it is necessary to make incisions on the window seal and to remove the fragment strictly in size.
• The valve is put on the double-glazed window and is attached with fastening dowels. Before installation remove the yellow protective film from it.
• Then, the seals that are included in the kit are mounted. If properly installed, all joints will be completely isolated, and air will penetrate the room only directly through the structure itself.

Supply ventilation to plastic windows allows you to constantly maintain a favorable microclimate in the room. About this aspect, we will talk in more detail later.

Plastic windows provide almost complete sealing of the room. In conditions of severe Russian climate this is a huge plus. In the warm season, the lack of oxygen is solved simply by airing, but in winter such a measure is impossible because of the severe frosts. The lack of fresh air is fraught with many problems:

• Fogging the windows.
• The appearance of fungus and mold on the slopes.
• The air mustiness. This creates discomfort in the room.
• In young children, allergic reactions may occur.

Additional ventilation in the room with plastic windows is provided by means of installation special valves. They have different design features, but their main purpose is to let outdoor air into the room without temperature losses. They cope with this function, albeit with varying degrees of efficiency.

Tip: In most windows, you can adjust the closing density. In the warm season, expose the doors in summer mode - in this case the frames will not close too tightly, which will allow oxygen to enter the room.

In what cases is the organization of additional air circulation necessary:

• If the house is home to young children. As already mentioned, a lack of oxygen can adversely affect their health.
• In rooms with many plants. Without oxygen, they will simply die out.
• When the house is heated by convectors or oil coolers. Such heaters monstrously dry the air.
• In production. In workshops (if they are associated with toxic substances) it is necessary to organize the maximum influx of fresh air.

All known varieties

The ventilation valve for plastic windows is only a simple device at first glance. It is divided into several varieties, which have significant design differences. They should be known to pick up the best option.

This is the simplest, and most importantly the cheapest option. With their help, outdoor air enters the room through small cutouts. The main advantages of this technology are as follows:

• Low cost.
• There is no need to dismantle the installed PVC windows.
• It guarantees the preservation of the soundproofing properties of the insulating glass unit.
• High speed and easy installation.
• Possibility of automation.

Among all the advantages, one was wormed, but a very important disadvantage is the weak bandwidth. Because of this, rebated ventilation with closed windows has a weak efficiency.

Slot

The fresh air into the room comes through special channels. Usually they have a size in the range of 160-400 by 10-16 mm. Typically, such a valve is equipped with two units - inlet and regulating. On more advanced models, it is one (universal). Pros of Technology:

• Absolute protection from external factors (precipitation, insects). This is provided by the presence of a regulating unit.
• High (in our case average) skipping ability.
• Can be used without dismounting the double-glazed windows.

A serious disadvantage in this case can be found only one - a relatively complicated installation. However, some models do not even have this lack (about this later). Therefore this category is the most popular now.

Overhead

In residential buildings, such structures are practically not used. This is due to their serious shortcomings:

• The thermal insulation properties of windows are seriously reduced.
• Sound insulation is reduced to almost zero.
• It is possible to install such a supply ventilation valve only before installing the double-glazed unit. In particular, you need to adjust the size of the opening.

However, this technology has found wide application in the manufacturing sector. The main reason for this is the highest throughput.

Market Leaders - Aereco and Air-box

Domestic market of valves by 90% was occupied by two manufacturers Aereco (France) and Air-box (Russia). You should have an idea about the features of their products:

A qualitative and practical option

Valves from Aareco are an overlay that has an attractive appearance (there are color variations) that fits into any interior. The most optimal installation option is during the manufacture of PVC windows. However, if the double-glazed windows are already standing, then installation can also be done. This will require a small drilling of frames.

There is a device of 8 (16) moisture-sensitive plates. Depending on the humidity level, they can open or close the barrier. And their work does not need power. The principle of operation is based on the physical law of thermal expansion.

You can even mount them into the wall. This method is used mainly in wooden buildings, because the milling of structural steel structures is extremely difficult. From the point of view of its qualities, this manufacturer looks the best analog on the market. However, it has an important drawback - a high price (from 2500 thousand rubles).

A cheaper analogue

The Russian manufacturer of air-box makes its products much simpler, which at the same time almost does not lag behind in efficiency from its more expensive "brethren". Such models allow to penetrate the street air through the space between the frame and the leaf. It seeps through the replacement of the regular seal. To control air flow, you must move the knob of the regulator.

Such models are much simpler, and require manual control. At the same time, they carry two very important advantages: low cost (on average from 400 rubles) and more simple technique installation. Air-box is installed in two ways - by means of milling the frame (as in the previous manufacturer) and by replacing the sealant (it will be discussed below).

Possible installation options

Forced ventilation in the window can be implemented in three ways, which vary greatly in complexity.

The most complicated method is the adjustment of the opening dimensions

The most time-consuming and costly method is associated with the installation of the above-mentioned overhead elements. They are mounted as follows:

• The existing double-glazed windows are removed.
• Expands the opening to the size of the lining.
• The glass unit is reinstalled.
• In the formed slot is installed a lining.
• Slots are covered with cement mortar (or something similar).

The technique looks like a killer and time-consuming one. Therefore, in this order no one does work, because it is fraught with the cosmic expenditure of forces, time and money. It is necessary to take care of additional ventilation in advance, that is, before installing the double-glazed windows.

The most thoughtful people, when ordering PVC windows, immediately plan and install additional air flow. For this purpose, the opening is slightly wider than that required by a double-glazed unit. This method is the most effective, and most importantly rational.

Installation Instructions for Aereco models

However, what to do if the glass unit is already standing? Models from Aereco are installed by a simpler technique. It consists of the following:

• Selects the location for the channel. If possible, this should be the least noticeable area.

Please note: additional window fittings should not interfere with the installation. Consider this fact when choosing a location.

• Then, the markup is done.
• We fasten the bar to the chosen place using special screws for PVC structures.
• Mark the location of the technological grooves on the porch.
• We remove the bar. With the help of a drill and electric jigsaw, we cut holes in the leaf and the frame itself.
• We set the bar again.
• We fix the valve with the help of special latches.

Such a procedure is relatively time-consuming. In addition, it requires the presence of special tools, which are far from everyone. Another factor is that a person without proper experience can not do the job accurately. Conclusion - installation of such a device is best entrusted to a specialist.

Air-box - installation without problems

There is one more technique that anyone can cope with. The manufacturer of air-box has created a model that is mounted without the use of tools. The kit includes a special sealant and self-tapping screws for PVC. The work is done in the following order:

• We choose the proposed installation site.
• We cut off in this place a regular sealant (which is located on the leaf).
• Insert the new one (from the kit).
• Remove the protective film from the valve.
• We fix it in place of installation of a new sealant with the help of special latches.
• We close the doors and make a mark on the frame along the length of the valve.
• Cut off the existing seal in this place and install a new one in its place (the same one from the kit).
