Exhaust ventilation in plastic windows. Plastic windows with ventilation: How to deliver fresh air to the apartment? How to choose the right ventilation valve

When repairing in any house or apartment, an important stage will be a change of outdated wooden window structures on new plastic windows. A similar change, as a rule, makes striking changes in the appearance of the entire premises that the owners of apartments only think about why they did not do it before. In addition, due to such a design, it is possible to significantly reduce the loss of heat and protect itself from street noise. In a strong room, the room will not be very hot, while maintaining the optimal microclimate indoors.

However, due to such a tightness, it may be disturbed or an apartment. IN apartment houses Soviet buildings ventilation channels do not always cope with the increasing load, so you need to know what is the ventilation of the supply type on plastic windows.

Most of the designs of the modern residential fund are presented the simplest ventilation systemswhich consist of ordinary kitchen drawing or hood installed in the bathroom. The influx of air masses is due to the slots in the window and doorway. This option is successfully applied in homes in which ordinary wooden boxes are installed. In the event that you install a set of plastic windows in such a house and install door seals, the influx of air masses becomes too limited, which can lead to a disruption of the microclimate of the room as well as:

To significantly increase the level of humidity, which leads to the fact that it becomes difficult to be in the room because of a strong stuffiness.
The rooms feels a pronounced discomfort associated with a disadvantage of fresh air.

Boxing: Important: Due to the lack of fresh air, such an unpleasant effect may occur as a "flow", when due to the lack of air in the ventilation mine, many odors from neighboring apartments begin to penetrate your, which, of course, is an extremely undesirable "side effect."

The ventilation system of plastic windows has a number of its features. Many note that in addition to the system without a draft, they begin such problems as strong fogging of glasses and stuffing.

In the event that users have claims to the manufacturer's company, then the recommendation is most often given to open the sash, exposing them to the "ventilation regimen". However, in this case, the advantages of the system are not fully understood.

It is recommended to start doing the problem with airing the room at the stage of purchasing plastic windows. When contacting a company that implements such structures, it is necessary to inhibit the following features:

Does the fortie present.
Is there a "comb". Although the cost of such a device is small, the benefits of its use is very sensible.
Is there a ventilation valve in this design.
Is there any possibility of self ventilation ..

Comb. Thanks to this device, you can adjust the sash in the desired position. Such a design has a number of differences from an ordinary folding mechanism and allows you to independently adjust the width of the disclosure of the flaps in different positions.

Thanks to the use of the window, you can guarantee the normal operation of the whole. Air, falling into the upper space of the room, mixed with the indoors, spreading directly by its volume. The main disadvantage is the fact that due to the complicated design, the price of a similar window increases significantly. In this case, the luminous flux in the room is a bit, but it is reduced in it.

Self-delayed windows. For their manufacture, a special kind of profile is used, which has holes in the exterior and internal upper elements. This ensures the flow of air masses into the upper part of the room. The window design involves the presence of a special chamber that performs the movement of the air flow, which returns to the room space, passing through heating.

There are certain limitations. For example, those who live in high floors, the installation of a wide and more expensive profile is not recommended. In this case, weak traction will not be able to ensure the influx of air masses in the required volume. In the heat, the full work of the system will be difficult, and it will not be able to work because of the features of the convection process.

To maintain a normal microclimate, both near plastic windows and in the entire room, it is necessary to use special ventilation valves that are universal devices.

To date, the following installation methods are applied:

Replacing old double-glazed windows to new, which have smaller dimensions to install the ventilation valve in the vacant space.
The valve, which is located in one of the elements of the top window sash.

The first method has certain disadvantages. In particular, the luminous flux is reduced, which increases material costs for additional sources of lighting. Professionals advise to use the second option, which is implemented in a short period of time (no more than half an hour) and is cheaper.

There are options with automatic and manual control. It is recommended to avoid such options in which the valves are not subject to adjustment. Managing manually is not only more profitable from a financial point of view, but also allows you to conveniently adjust the flow of air flow and reduce heat loss. Thanks to the automatic mode, you can constantly maintain a certain humidity and room temperature.

The best option is to combine two options, since the best results You can achieve precisely with a combined control system.

The outflow and air flow should be carried out according to the norms of air exchange. In order to achieve the best noise absorption, ventilation valves are installed on modern window designs with similar capabilities and technical specifications.

Since during operation in the cold period of the year, difficulties arise, since it is not always possible to predict the appearance of the nondes, condensate or. In order to remove certain "risk factors", it is recommended to draw the following actions:

Provide high thermal insulation of valves, special attention is paid to the part located outside the room.
Install the "heat chart" of plastic if the body is used at the moment.

The valve is a rather complicated device, so its price can be quite high.

Slit valves exist both in mechanical and automatic execution. The room is ventilated by penetrating fresh air through ventilation channels. The advantage of the slotted type valves is that they are easy to install and provide a normal air exchange without having to disassemble.
Fold valves allow for a normal influx of fresh air, which is carried out due to folding cuts in window blocks. Differ low throughput and excellent sound insulation indicators. Possess at the same time a low cost.
Overhead valves. Have the biggest influx of air and have a number of serious flaws. For example, they cannot be installed on already mounted plastic double-glazed windows, as well as their use worsens the indicators of heat and sound insulation.

The use of overhead climatic valves is most common to solve production and industrial tasks, in apartment buildings this method is not particularly common. The most common way to install plastic windows with ventilation is the Binding method. Regulation of double-glazed windows is carried out in both automatic and manual mode. Automatic control allows you to achieve the creation of optimal and reduce the level of humidity.

Thanks to the use of valves, it is possible to achieve a full-fledged isolation from noise sources from outside and prevent the appearance of drafts, damp, condensate and fogging. Since mold, dampness and fungi is not the most the best way Influence the human body, lowering immunity and performance, the installation of the ventilation of plastic windows is recommended to trust this professionals with great experience and knowledge in its field.

Regulatory valves do not need special care and maintenance. It is quite literally once a year to clean their surface from dust and various contaminants. For normal operation of the ventilation of plastic windows, the correct functioning of an ordinary exhaust is necessary. Otherwise, condensate can accumulate in the room and the windows may accumulate.

conclusions

For the efficient operation of all the options described above, the ventilation system will be required. Despite the fact that the options described above allow you to realize the normal exchange of air in the room, there are various factors that can affect it.

The principle of ventilation is based on permanent air circulation in the apartment. However, modern plastic and metal glass windows Prevent free air exchange. To ensure air intake in the apartment in the desired volume and make accommodation in it as comfortable as possible, set the trim valve to the window - compact, uncomplicated device.

Most of the residential urban buildings refers to economical housing, which means that during the construction of height, the scheme of natural ventilation is used. It lies in free circulation aerial Inside the rooms, which is carried out due to the difference in temperatures on the street and in the building.

Air path in a typical three-bedroom apartment

Fresh air enters through window gaps, windows, open shutters, as well as small slots under the door canvases specifically provided for this purpose. The exhaust medium is excreted through the technical openings located in the bathrooms and in the kitchens, in general business vents and mines.

If there is a violation of the inflow and exhaust scheme, the microclimate in the apartments will violate that it will immediately affect the well-being of residents. Duchot, increased humidity and dust particles provoke the occurrence of diseases in humans, as well as the appearance of mold.

To establish air movement, use various devices, for example, split systems or conventional fans inserted into the ventilation channels.

Channel ventilation Install in luxury houses

In apartments with hermetic double-glazed windows exist more simple solutions, for example, the installation of the supplit valve on a wooden or plastic window. The compact device will supply air in constant or cyclic mode, the choice of which depends on the required for comfortable accommodation temperature and humidity parameters.

Distribution valve for PVC windows

Construction and nuances of mounting depend on the installation site of the device. For example, wall models most often mounted under the window, close to heating radiator or convector. It is important that at least a partially heated air flow inside the room. The window devices put directly on plastic windows - precisely about such devices and will be discussed below.

Appointment and design of the supply valve

Supply devices, as well as micro systems, are designed to improve the microclimate in residential rooms, offices and industrial premises. They provide a full amount of fresh air, which in time heats up, rises up and moves towards the ventilation holes.

Device painted in the color of the window frame

There is one nuance, which should be remembered when choosing and installing any supply device: its work becomes effective only when the exhaust function is established. If all-friendly ventilation mines are clogged with construction garbage or the temperature on the street is the same as in the house, there will be no ventilation. In this case, the installation of equipment for forced circulation is required: exhaust, fans, air conditioners, split systems.

The design largely depends on the type of valve, but most of the popular folding models consists of the following parts:

outdoor unit for air intake covered by a technical visor;
internal module fixed on the frame from the side of the room;
the connecting channel cutting into the frame and resembling a sleeve.

There are also universal monoblock systems that are a single element. Installation of such models does not cause difficulties.

Option model installed in the top of the window sash

From which parts it consists of a specific model, it is better to know before buying. To do this, you can ask the installation scheme from the seller-consultant. Perhaps the selected model is not suitable for the method of installation, dimensions, form or color.

Types of window valves

Depending on the various factors, all valves on the windows for supply ventilation can be combined into groups. For example, there is a classification at the place of installation on plastic glass. If desired, the device can be fixed in the following points:

horizontally on the upper frame crossbar;
in the gap formed by two connected plastic elements;
in the place of touch of plastic and glass;
from the end of the sash;
on the additionally installed item.

Usually choose instruments that merge with plastic over a shade and do not interfere when opening / closing the sash.

Mounting place - top plane of the window sash

By constructive features Products are divided into slotted, overhead and folded. The first are horizontally directly on the plastic surface of the sash. Thanks to the mobility of the frame, the device can be fixed without dismantling the glass pack.

The overhead models in the household sphere are practically not used, since their installation is carried out before inserting window structures. Fold devices "implant" in the frame, pre-cutting the hole. Installation has some nuances, so it is better not to fix the supply valve on the PVC windows with their own hands, and to instruct this responsible procedure by a specialist - a representative of the company implementing the company.

Exterior type of folding type valve

In terms of performance, the supply products may be small, medium or great performance. Instruments with minimal indicators - up to 6 m³ / h - used for small rooms that do not need volumetric air exchange. One thing is enough to equip the ventilation in the bedroom, a living room or a children's room with an area of \u200b\u200bup to 20 m².

The products of the average category with parameters up to 35 m³ / h are suitable for large rooms Or the premises where active air exchange is needed. Great productivity - 150 m³ / h and more - needed for halls in which they accumulate a large number of People, or for industrial premises.

Advantages of automatic devices

Regardless of the design, all products are divided into three subgroups:

without the possibility of adjustment;
with manual adjustment;
automatic.

The first subgroup is the simplest devices resembling insert. Through a small hole, the street atmospheric environment constantly penetrates the room. Since it is impossible to stop the feed, the productivity is small. Such instruments are well installed in utility rooms or corridors.

Mechanical models are managed manually. They also differ in simple design, nevertheless equipped with a small curtain or valve, with which you can interrupt the air supply. Devices are installed at a convenient and accessible place. If the temperature on the street has decreased sharply, it is enough to close the valve. Advantages of models - low price and simple control, disadvantage - periodic lack of ventilation.

Manual valve

The third subgroup is recognized as the most successful, as it works independently. Thanks to temperature and humidity sensors, the device turns on at the right moment, and when the microclimate in the room becomes perfect, the ventilation stops.

The most expensive models not only automatically change the modes of operation depending on the humidity and temperature, but also adjustable by automation. You can program an automatic trim valve on the plastic window so that it is closed in the afternoon and turn on overnight or performed a more active venting room before arriving home.

Rating Popular Marks

Famous manufacturers of ventilation devices do not need additional advertising, as long ago are present on russian market And have proven themselves only from the best side. Their products are advanced and has a lot of advantages compared to less popular competitors. Consider some of them.

1st place - Russian company Air Box

The range of suggested products is small, however, among the air ventilation valves for the Air Box windows, it is easy to find the desired option, since there is manual and automatic, with milling and without it.

You can choose a model of three series: Comfort, Standard and Comfort C. Comfort valves have two installation options - built-in and fixed on the frame from above. Depending on the installation, the performance of the device changes slightly: it reaches 31 m³ / h without milling, with the rubber of the special opening increases to 42 m³ / h. Model adjustment is done manually.

After installing Air Box merges with the plastic basis

For fans of automatic devices, the Standart series is offered. The automation is limited and is aimed at adjusting the speed of air outdoor masses. If the wind is enhanced, the moving elements go to another position, thereby weakening the pressure. It is necessary to protect the house from drafts. But the AIR Box Standart trim valve for PVC windows has a very significant minus - low performance. It misses only 5 m³ / h.

Comfort S models are designed for wooden frames. Before installing in the horizontal upper crossbar, it is necessary to cut through three holes: two to insert the elements of the device and the third for fasteners. Performance of devices - 41 m³ / h.

2nd place - French manufacturer Aereco

Today, there are three window series of aircraft supply valves on plastic windows: EMM², EHA², EMM. All of them are hygrorgulated. This means that when changing humidity in the room, the instruments independently change the position of the elements and reduce or increase air flow.

EMM Aerco Design in Cut

The presence of a protective visor in the designs of EMM² and EMM allows to reduce the degree of noise to 37 dB. The EHA² series models have an enhanced design and equipped with a manual switch. Emm modification has the ability to adjust the air jet: vertically or under a slope.

3rd place - Polish brand VENTAIR

Supply devices successfully combined aesthetics, functionality and moderate cost. The instrument performance is enough to ventilate residential premises - up to 25 m³ / h. Adjusting devices occurs automatically, thanks to pressure and humidity drops.

The advantage of models is that in winter or in windy days reduce the flow of incoming air, thereby protecting against drafts and the loss of heat indoors.

In addition to the producers listed, products under the brands of Systemair, Vents, Sinax Air, Rehau, Fläkt Woods, Gealan, Aldes, Siegenia-Aubi have proven well.

Instructions for installation of the supply valve

Household supplies have low cost, but more importantly - the possibility independent installation. The instruments are easy to mount on the window sash, while you need a minimum of working tools: a construction knife, a screwdriver. A stepladder will also need if the installation site is high. For example, take instructions for installing a slit model.

Step-by-step procedures:

Step 1 - Checking the supply of the supply product. The kit includes the device itself, three seals sealing (one - 35 cm and two - 16 cm), self-tapping screws to the frame.
Step 2 - trimming and removing the sealer from the top of the sash. For this we take the valve and, focusing on its length, cut out a piece of 35 cm.
Step 3 - Installation of plastic parts. We take plastic dowels from the kit and insert them into the empty from under the remote seal.
Step 4 - Installation of the valve. Remove protective film And we put the device on the sash so that the mounting holes are opposite the dowels.

Photo adjustment: how to install a trim valve on a plastic window

Step 5 - twisting of the self-tapping screws. We insert alternately screws into the holes and with the help of a screwdriver we twist them.
Step 6 - Installation of seals from the kit. Instead of a remote seal, insert two new 16 cm.
Step 7 - Installing the seal on the adjacent frame. To create a gap between seals, change the rubber gasket and on the frame - we set the one that is present in the kit (35 cm).

At the end of the work, we close the sash, check the functionality of the supply valve. If there is an adjusting handle, move it to the left / right, seeking changes in the volume of incoming air.

By this principle, most of the slotted supply devices are mounted. However, there are models whose installation is fundamentally different. Such devices include a trim valve knob on a plastic window. Externally, it resembles an ordinary handle to open and snatch the sash, but the lower part of the case is a ventilating valve.

Valve stick before mounting

The installation is made similarly to the installation of a conventional handle, but an additional hole is cut for air intake.

Sometimes additional adjustment is required after installation. It is usually advisable if the principle of operation of the device is not yet understood. To understand the functioning of the device, you must smoothly move the handle and monitor the result. If the air flow seems weak, the magnitude of the clearance should be increased.

Comfortable air supply setting

If the installation of the device seems complicated, it is necessary to study the instructions more closely. If after that with the installation and configuration still arise problems, invite the wizard.

Video of the device and installation of the supply valves

An interesting and useful video about the supply valve on the Aereco plastic windows. Review device I. detailed instructions on installation:

Briefly about the value of the supply ventilation from the manufacturer Air Box:

Video installation for installation with your own hands:

Alternative expert opinion on the efficiency of climate control window valves. Be sure to look at the roller before disrupting the integrity of the internal sealing window of the window:

Manufacturers assure that the supply valves will help to establish a comfortable microclimate, get rid of drafts and condensate on the windows. Good ventilation is the key to strong sleep and excellent well-being of all family members, but it is unlikely to wait for miracles from an inexpensive household device.

The ventilation valve for plastic windows allows to solve a lot of problems: drafts, stuffing in the room, condensate on the glasses, which leads to the appearance of mold. The main advantage of modern window blocks from PVC profile - tightness, turns into a drawback under certain conditions: when it is necessary to ventilate the room, and you cannot open the windows for various reasons (winter season, a pretty child, etc.).

The ventilation modes are not always suitable: either drafts arise, or the gap between the frame and the folding profile is too thin, which is why the desired volumes of fresh air in the room do not come.

folding;
slotted;
overhead.

Fold valve

The first two options are installed on the windows that are already exploited. Installation in this case is actually done with your own hands. The slot valve is equipped with intake and regulating blocks, in some models a universal ventilation unit is provided - the combined option.

Outside, protection is installed on the slot ( mosquito net) From Sora and insects. For ventilation, it is provided for a slot length from 170 to 400 mm and a width of no more than 16 mm.

The fold valve creates small gaps in the windows. Such a principle of operation does not provide high efficiency, but the windows sound insulation is not disturbed. There is a more effective design - invoice. However, this option is problematic to establish your own hands.

In addition, its effectiveness is quite high, which can be a hindrance when creating a normal small housing microclimate. Therefore, such structures are more often used in production.

Ventilation wall view

Function valves of supply ventilation on the principle of pressure drops. At the same time, colder air is dragged into the room, and warm air is fed from the valve. So there is passive ventilation, therefore its efficiency falls when the temperature is raised on the street above +5 degrees. To enhance exhaust traction in the warm season, it is recommended to use a forced ventilation system.

Select design

In the case when condensate is formed on the windows, in the room is stuffy and have to perform ventilation, you should adjust the accessories and check the seal. If the structural disorders have not been detected, you can consider the option of installation on the sub-valve window with your own hands.

Basic selection criteria:

the efficiency of work, which is determined by the parameters of the device and the number of people living in the apartment, for example, the sufficient intensity of the air exchange in the room for one person can provide the influx of 30 cubic meters. m / h;
the noise level during valve operation should not exceed 35 dB;
in the cold time of the year, the valve is not ignited, in the design there should be a "thermal gap", made of plastic, it is installed between the inner and outer surface of the valve body;
design type: slit, foldable - these are the main options that can be easily installed on the window with your own hands;
management method: automation, manual or combined control.

The most popular designs: Aereco, Air-Box (Comfort, Comfort-S), Regel-Air. Each of the options has its advantages, but almost all of them are easily installed with their own hands, except for the Comfort-S execution, which is intended for a deaf window and mounted by milling at the top of the profile. Comfort model represents a group of folded-type products.

Aereco products are presented different options: Feed the jet in the inclined and direct direction. In addition, these valves are characterized by broad functionality, since in addition to the main task, provide a normal level of humidity in the room due to the function of hygronalization. Regel-AIR valves represent a group of folding structures. Their feature is a movable plastic pen, responsible for adjusting the air flow.

Installation

To avoid problems when installing, it is recommended to select certain designs: folded, slotted. The window should be released from foreign objects, Remove the speed. For mounting in the window, you need to cut part of the sealing cord on the frame and sash.

It is easy to make it yourself using a stationery knife. The valve itself is attached by means of a dowel to the window sash.

Support valve installation steps

To install the folding structure, it will take 3 screws, the seal is paved between them, which is included in the kit. Usually enough material is laid by the manufacturer. By means of screws, the valve is attached to the window profile.

Care and maintenance

Considering that dust penetrates with air flow to the room, it is necessary to periodically perform the purification of the valulation. Enough to do it once a year. With a soft cloth, a plastic surface and a seal is wiped. The adjustment of the mechanism is preferable, because the design characterized by unchanged air flow parameters does not provide optimal conditions in room.

The best option is the device with automation, in such models there are hygrorgulation sensors. The principle of their action is based on tracking air humidity indicators in the room, in accordance with this, the narrowing or expansion of the flow channel occurs.

Manual adjustment is performed by changing the position of the damper. This method has a significant drawback, which lies in the difficulty of determining the desired position of the flap under various weather conditions.

Thus, the installation of the supply valve can significantly improve the microclimate in the room. If installation is planned own forcesIt is recommended to choose a slot or fold-type model. Moreover, the second option is easier to implement, since the slotted type requires a smooth slot in the profile. Given that proper Installation You can avoid a number of problems: condensate on windows, drafts, inefficient air exchange in the room.

In the process of arranging its own living space, the window ventilation is provided for not by each owner. At first glance, this question is not of paramount importance, but after some time it becomes clear that without the window ventilation system it is difficult to present a comfortable stay in the residential room.

The problem of air exchange has always been relevant for buildings with throughout the windows. Every experienced builder is aware of how important it is to equip competent system Ventilation in the windows. But most of the unenmended people do not even assume that the air exchange system needs such a system.

Main Factors of Window Ventilation Factors

As you know, ventilation helps to ventilate the room, releasing the recycled air outside and simply filling the housing with oxygen. This process is designed to provide healthy image Life of any person, he has an important sanitary and hygienic value in the living environment.

In addition to the effect on health, the right air exchange helps to save electrical and thermal energy in the House. In many old houses, the window frames have many cracks, they do not have the necessary sealing. On the one hand, it helps to provide a natural air exchange, allowing you to air the house. Air passes through all the rooms where windows are installed. On the other hand, it becomes the cause of heat transmission during the cold period of the year, which ultimately leads to external monetary costs aimed at ensuring the required heating of residential premises.

Modern models PVC windows, aluminum and wood with high-quality thermal insulation and sealing solve this problem, but at the same time create another. Natural ventilation It is completely lost, and the recycled air does not destroy out of the room. Without receipt of the supply air, the functioning of the exhaust system is broken. A family of 3-4 people highlights up to 10-15 liters of wet sediments per day (sweat, breathing, cooking, cleaning of the room, etc.). The normal amount of fresh air is reduced. At the same time, the level of carbon dioxide, as well as other harmful substances allocated from the environment (there can be included in household appliances).

Thus, the house becomes stuffy, on the glasses, walls and in arched openings, condensate is formed, which creates a favorable environment for the appearance of fungus, mold and harmful bacteria. Today, all houses are saturated various species Household appliances. Few know that it is one of the sources of the formation of allergenic substances. If you have long to stay in an unbelievable room with household appliances, then the head begins to hurt (the attacks of choking and allergies are less likely). To prevent such consequences, it is necessary to provide the right air exchange indoor.

Of course, the room can be airfilled by the simplest way by opening the window. But in this case, dust penetrate into it, a poplar fluff, a strong wind, and in winter - also cold air. For this reason better decision There will be a supply window ventilation.

Supply window ventilation system

Ventilation Mounting Tools: Knife, Roulette, Perforator, Spatula.

The main task of such ventilation is the receipt of a continuous flow clean air Inside the room. The formation of clean air is due to the presence of a special filter in the supply ventilation, in addition to which a special mesh against insects is. Such an air exchange system in no way disrupts hermetic and sound insulation of windows, that is, modern technological solutions Do not lose their main advantages.

The main advantages of the supply ventilation:

Absolute security for a child.
The mechanism does not need power.
Convenience during operation (manual control).
There are properties of noise insulation.
The system is equipped with a mileage network.
There is an integrated protection system from the penetration outside, which allows to provide air exchange even during the absence of the owner.
The functioning of the mechanism does not depend on atmospheric and natural conditions.
There is a control system preventing the formation of drafts.
The device has a compact size, it is almost imperceptibly for the naked eye.
Clean air filter is able to clean the incoming air from harmful smoke.
Installation is made in any types of windows.
The device does not require dismantling the window or its reinstallation.
Low cost.

The current standards indicate that the air exchange must be made at least 1 time per hour. Supply window ventilation system is able to supply room with clean air even at such a level. Modern windows can not do without such a system.

Principle of Support Ventilation

The supply system of window ventilation functions based on two parts: the outer panel (installed on the outside) and the internal (mounted from the inside). Both details are combined with a small opening through which fresh air comes. The outer panel is equipped with an automated valve floating in a pure air stream. When the difference in pressure increases, the valve is lifted and closes the opening. Accordingly, when decreasing the difference, the valve is lowered. According to such a scheme, the system supplies a residential room with a supply air, regardless of natural phenomena.

The outer panel provides protection against rain in the opening. It has a mounted mosquito net. Interior Equipped with a panel with a slope intended for controlling the air flow, which is carried out using a special cord.

In the process of installing the air exchange system, you must follow certain rules. For example, the trim air should flow in smaller quantity than the exhaust.

Usually, when choosing a mechanism, a qualified specialist takes into account all the nuances of the living space, but they can be estimated independently.

Installation should be made according to a specific scheme: 1 or 2 devices are placed in points, which are located in the most remote places from the exhaust channel of the kitchen and bathroom. This will provide an optimal ventilation level in all rooms at home. When installing, you should pay attention to the fact that one device is intended for 2-3 hoods. Otherwise, the air exchange will be incorrect.

Other types of window ventilation

In the case of poor functioning of the drawing in the house, condensate appears on windows and walls, it is often formed mold in the corners of profiles. Under such conditions, it is better not to install a powerful support ventilation. It is necessary to select special micheology devices like Fresh AIR, helping to reduce the level of condensate formation in window openings.

If you live in a multi-storey building, where the hood is equipped competently (this can be checked with a paper sheet, which caused to the ventilation grid: it will not crawl), it is advisable to equip the apartment with an air ventilation system. It is not recommended to install systems that are more powerful, since there is a possibility for the formation of a reversing air flow coming from the exhaust.

In the case of the selection of window ventilation for the apartment or the house of large sizes, without a qualified specialist can not do. Only he can produce the right calculation of the air exchange system power and place the location points of the ventilation equipment.

For special premises, where a high level of humidity is constantly maintained, it is customary to use ventilation systems intended for winter gardens.

Window with ventilation valve: Benefits and Disadvantages

To eliminate the fissures of the window, access to the room of fresh air has been developed by the supply vent valve. They are installed directly in the frame of the plastic window or in the wall next to it. Among the advantages of the ventilation valves:

The ability to adjust air flow, including automatic mode;

High level of noise protection;

Original design;

The ability to install on existing windows.

Among the disadvantages of the ventilation valve - its frost, which in winter leads to a violation of its work. This is due to the fact that most of the products in our market are represented by European companies that developed valve for countries with a softer climate.

The disadvantages of the ventilation valves include a relatively high cost of equipment, which is noticeably increasing the price of a conventional window. When operating the PVC windows with ventilation, it should be remembered that the positive effect will be possible only when proper work Hood.
