Varieties of window ventilation systems. Ventilator for plastic windows: ventilation system Check valve for windows

Metal-plastic structures provide high tightness to housing, they do not let in extraneous sounds and cold in winter. With all its advantages, it is worth noting the main drawback - a significant reduction in the flow of fresh air. By installing a supply air vent for plastic windows, you can solve this problem.

We are talking about a product with small holes located in the upper part of the sash. With their help, the air exchange in the room is normalized. Small ventilated structures prevent the penetration of street noise, providing the interior space with the long-awaited silence, peace and tranquility. The inlet ventilation valve is suitable not only for plastic, but also for wooden and aluminum windows.

In most openings, the closing density is easy to adjust. For a warm season, it is better to set the sashes in such a way that there is a small free space between the frame and the double-glazed window, and oxygen can freely enter the room.

Possessing certain practical skills and following the instructions, each owner can organize an effective one in a house or apartment. But the best part is that window inlet valves can be installed with your own hands without the help of specialists.

Ventilation (supply) damper efficiency

Many people have a natural question - how effective are these small structures for air exchange? Before purchasing supply valves, experts advise checking their effectiveness by carefully studying the technical specifications, consulting with the seller, it will not be superfluous to read the comments of those who have already bought them.

Checking the efficiency is quite simple, and it is not at all necessary to purchase ventilation solutions. All that is required is to remove the seal fixed on the sash. It should not be removed or cut off completely, it is enough that it just hangs in a free position for a while (optimally 2-3 days). After their expiration, pay attention to a number of criteria and parameters:

• Are there drafts in the room?
• whether the general noise background has increased in the room;
• the appearance of condensate "fogging" on the glass;
• temperature change in the room.

After completing the experiment, the window seal returns to its original place.

Installing a supply valve on a plastic window will certainly lead to a decrease in the temperature in the room. This is due to the fact that cold air from the street enters the room. If we are talking about an efficiently functioning heating system, you can notice a difference of 3-4 degrees.

If there is no effect, it is advisable to abandon this product in favor of a supply valve installed in the wall.

Supply ventilation valve: principle of operation

For competent and high-quality equipment of supply valves for metal-plastic or wooden windows, you should carefully study the mechanism of their operation. This is one of the most crucial stages, since subsequently it will be necessary to make a hole in the frame about 30 cm long and at least 1 cm wide. At the final stage, it will be covered by the case of the ventilation device.

It will not work to dismantle the supply structure without opening a slot in the upper part of the profile. The decision to install is made reasoned and balanced.

Supply valves for plastic windows are an important passive component. Through a small hole, cold air is taken from the street and directed inside the housing. Warm oxygen is removed through the ventilation ducts. Physical laws set these masses in motion, due to which the functioning of products is ensured at an air temperature of +5 degrees.

In hot summers, passive air exchange works only with forced exhaust.

The valve on the plastic window works effectively, subject to several conditions:

• outside the window, the air has cooled to a temperature of less than +5 degrees;
• the presence of a working ventilation system in the house or apartment;
• between adjacent rooms there is a full air exchange;
• hermetic front door (to level the effect of "sucking" oxygen).

Many owners are concerned about the question - does the ventilation valve for plastic windows freeze over? Such an undesirable effect is possible, but only if amateurs were involved in the installation. Even in severe frosts, it will not be possible to close the hole completely.

Do not be afraid of increasing noise levels in the living space after the installation of the ventilation hole on the window is completed. Fresh oxygen enters through a small hole, so the reduction in sound insulation will be negligible.

Supply ventilation valve: do-it-yourself installation on a plastic window

Installing the ventilation structure is easy. For an experienced master, 30-40 minutes is enough for this.

Mounting without milling

First you need to prepare a few tools:

• air exchange product;
• well-sharpened knife;
• screwdriver;
• half meter line.

To install the inlet valve, it is necessary to dismantle part of the window seal

Do-it-yourself inlet valve on plastic windows is installed only after preliminary marking of the flap. This is what a line is for. The sequence of work is determined by the design features of the valve. In most cases, it is enough to replace the standard seal with a complete one.

As for other models, PVC windows require no more than 1 hole in the profile structure. The most preferred option is the first one, since it is very problematic to make an even and neat gap with your own hands.

Manufacturing companies in 99% complete products with detailed step-by-step instructions, with which you can quickly equip a window opening with an appropriate solution.

Step-by-step instructions for installing a supply valve with your own hands are presented in the video:

Milling installation

Milling means cutting a small hole in the block of the window opening.

To work, you will need several materials and tools:

• sharp construction knife;
• powerful electric jigsaw;
• drill and a set of drills (in most cases, enough for 5 and 10 mm);
• file;
• a template for a future valve of a suitable size;
• sealant.

In order for the supply ventilation in plastic windows to provide an optimal level of air exchange, it is important to strictly observe the following sequence of actions.

Supply ventilation valve: owner reviews

The structures installed by the methods described above perfectly cope with the issue of effective air exchange in the room. And even the smallest apartment from a "thermos" can be turned into a comfortable home with an impeccable level of ventilation.

The owners emphasize that such devices are not advisable to use in those regions of the country where severe frosts are rapidly replaced by rising temperatures. In this case, frost forms on the valve, and the unit will not be able to work in principle.

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 mildew.

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 sealant 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 sash 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.

The principle of operation of ventilation is based on the constant circulation of air in the apartment. However, modern plastic and metal-plastic double-glazed windows prevent free air exchange. To ensure the flow of air into the apartment in the right volume and make living in it as comfortable as possible, install a supply valve on the window - a compact, simple device in design.

Most of the residential urban buildings are classified as economical housing, which means that the construction of high-rise buildings uses a natural ventilation scheme. It consists in the free circulation of the air inside the rooms, which is carried out due to the temperature difference in the street and in the building.

Air path in a typical three-room apartment

Fresh air enters through window gaps, vents, open window sashes, as well as small gaps under the door leafs, specially provided for this purpose. The spent environment is discharged through technical openings located in the bathrooms and kitchens, into the general house ventilation ducts and shafts.

If there is a violation of the supply and exhaust scheme, the microclimate in the apartments will be disturbed, which will immediately affect the well-being of the residents. Stuffiness, high humidity and dust particles provoke the occurrence of diseases in people, as well as the appearance of mold.

To establish air movement, various devices are used, for example, split systems or conventional fans inserted into the ventilation ducts.

Duct ventilation is installed in the houses of the elite category

In apartments with sealed double-glazed windows, there are simpler solutions, for example, installing an inlet valve on a wooden or plastic window. The compact device supplies air in a constant or cyclic mode, the choice of which depends on the temperature and humidity parameters necessary for comfortable living.

Supply valve for PVC windows

The design and nuances of installation depend on the installation location of the device. For example, wall models are most often mounted under a window, close to a heating radiator or convector. It is important that at least partially heated air enters the room. Window devices are placed directly on plastic windows - it is about such devices that will be discussed below.

Purpose and design of the inlet valve

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

Appliance painted in the color of the window frame

There is one nuance that should be remembered when choosing and installing any air supply device: its operation becomes effective only when the hood is functioning properly. If the general house ventilation shafts are clogged with construction debris or the temperature outside is the same as in the house, ventilation will not be carried out. In this case, it is mandatory to install equipment for forced circulation: hoods, fans, air conditioners, split systems.

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

• outdoor unit for air intake, covered with a technical visor;
• indoor module mounted on the frame from the side of the room;
• a connecting channel cut into the frame and resembling a sleeve.

There are also universal monoblock systems, which are a single element. Installation of such models is not difficult.

Version of the model installed at the top of the sash

What parts a particular model consists of, it is better to find out before buying. To do this, you can ask the installation diagram from the sales assistant. It is possible that the selected model does not suit the installation method, size, shape or color.

Types of window valves

Depending on various factors, all window dampers for supply ventilation can be combined into groups. For example, there is a classification according to the place of installation on a plastic double-glazed window. If desired, the device can be fixed at the following points:

• horizontally on the top rail of the frame;
• into the gap formed by two connected plastic elements;
• at the point of contact between plastic and glass;
• from the end of the sash;
• on an additional element.

Usually, devices are chosen that merge with the plastic in shade and do not interfere when opening / closing the valves.

Place of installation - the upper plane of the window sash

According to the design features, the products are divided into slotted, overhead and folded. The first are placed horizontally directly on the plastic surface of the valves. Thanks to the mobility of the frame, the device can be fixed without dismantling the double-glazed window.

Overhead models in the domestic sphere are practically not used, since their installation is carried out before the insertion of window structures. Folded devices are “implanted” into the frame, having previously cut a hole. Installation has some nuances, so it is better not to fix the inlet valve on PVC windows with your own hands, but to entrust this responsible procedure to a specialist - a representative of the implementing company.

Appearance of the rebate type valve

In terms of performance, inflow products can be of small, medium or large capacity. Devices with minimum performance - up to 6 m³ / h - are used for small rooms that do not need volumetric air exchange. One piece is enough to equip the ventilation in the bedroom, living room or children's room up to 20 m².

Products of the middle category with parameters up to 35 m³ / h are suitable for large rooms or rooms where active air exchange is required. Large capacity - 150 m³ / h or more - is needed for halls in which a large number of people accumulate, 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 an insert. Through a small hole, the outdoor atmospheric environment constantly penetrates into the room. Since it is impossible to stop feeding, the productivity is low. It is good to install such devices in utility rooms or corridors.

Mechanical models are controlled manually. They are also simple in design, but they are equipped with a small shutter or damper, with which you can interrupt the air supply. Devices are installed in a convenient and accessible place. If the temperature outside drops sharply, it is enough to close the valve. The advantages of the models are low price and simple operation, the disadvantage is the periodic lack of ventilation.

Manual valve

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

The most expensive models not only automatically change operating modes depending on humidity and temperature, but are also regulated using automation. You can program the automatic supply valve on the plastic window so that it closes during the day and turns on at night or more actively ventilates the room before the owners arrive home.

Rating of popular brands

Well-known manufacturers of ventilation devices do not need additional advertising, as they have been present on the Russian market for a long time and have proven themselves only from the best side. Their products are cutting edge and have a lot of advantages over less popular competitors. Let's consider some of them.

1st place - Russian company AIR BOX

The range of products offered is small, but among the supply ventilation valves for AIR BOX windows it is easy to find the right option, as there are manual and automatic ones, with and without milling.

You can choose a model from three series: Comfort, Standard and Comfort C. Comfort dampers have two mounting options - built-in and mounted on the frame from above. Depending on the installation, the performance of the device changes slightly: without milling it reaches 31 m³ / h, with cutting through a special hole it increases to 42 m³ / h. Models are adjusted manually.

After installation, the AIR BOX merges with the plastic base

For fans of automatic devices, the Standart series is offered. Automation is limited and aimed at adjusting the speed of air street masses. If the wind increases, the moving elements move to a different position, thereby weakening the pressure. This is necessary to protect the house from drafts. But the AIR BOX Standard supply valve for PVC windows also has a very significant disadvantage - low performance. It passes only 5 m³ / h.

Comfort S models are designed for wooden frames. Before installation, three holes must be cut in the horizontal top bar: two for inserting the device elements and the third for fasteners. Productivity of devices - 41 m³ / h.

2nd place - French manufacturer AERECO

Today, three Aereco window series of inlet valves for plastic windows are produced: EMM², EHA², EMM. All of them are hygroregulated. This means that when the humidity in the room changes, the devices independently change the position of the elements and reduce or increase the air flow.

Aereco EMM construction in section

The presence of a protective visor for the designs EMM² and EMM allows you to reduce the noise level to 37 dB. Models of the EHA² series have an advanced design and are equipped with a manual switch. The EMM modification has the ability to adjust the air jet: vertically or sloped.

3rd place - Polish brand VENTAIR

Supply devices successfully combined aesthetics, functionality and moderate cost. The performance of the devices is sufficient for ventilation of residential premises - up to 25 m³ / h. Adjustment of devices occurs automatically, due to pressure and humidity drops.

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

In addition to the listed manufacturers, products under the brands Systemair, Vents, SINAX AIR, Rehau, Fläkt Woods, Gealan, ALDES, SIEGENIA-AUBI have proven themselves well.

Inlet valve installation instructions

Household air inlets have a low cost, but more importantly, the possibility of self-installation. The devices are easy to mount on the window sash, while a minimum of working tools is required: a construction knife, a screwdriver. You will also need a stepladder if the installation site is high. For example, take the installation instructions for the slot model.

Step by step procedure:

• Step 1 - checking the configuration of the supply unit. The kit includes the device itself, three pieces of seals (one - 35 cm and two - 16 cm each), self-tapping screws for fastening to the frame.
• Step 2 - cutting and removing the seal from the top of the sash. To do this, take the valve and, focusing on its length, cut out a piece of 35 cm.
• Step 3 - installation of plastic parts. We take the plastic dowels from the kit and insert them into the hollow from under the removed seal.
• Step 4 - valve installation. We remove the protective film and put the device on the sash so that the mounting holes are opposite the dowels.

Photo hint: how to install a supply valve on a plastic window

• Step 5 - tightening the screws. We insert the self-tapping screws into the holes one by one and use a screwdriver to twist them.
• Step 6 - installation of seals from the kit. Instead of the removed seal, we insert two new ones 16 cm each.
• Step 7 - install the seal on the adjacent frame. To create a gap between the seals, we change the rubber gasket and on the frame - we put the one that is included in the kit (35 cm).

At the end of the work, close the sash, check the functionality of the supply valve. If there is an adjustment knob, move it to the left / right, achieving a change in the volume of incoming air.

According to this principle, most of the slot-hole supply devices are mounted. However, there are models whose installation is fundamentally different. Such devices include a supply valve-handle on a plastic window. Outwardly, it resembles an ordinary handle for opening and snapping the sash, but the lower part of the body is a ventilation valve.

Handle valve before installation

Installation is carried out similarly to the installation of a conventional handle, but an additional hole is cut for air flow.

Sometimes after installation additional adjustment is required. It is usually appropriate if the principle of operation of the device is not yet clear. To understand the operation of the device, you need to smoothly move the handle and monitor the result. If the air flow seems weak, the gap should be increased.

Comfort air setting

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

Video materials about the device and installation of supply valves

An interesting and useful video about the supply valve for AERECO plastic windows. Device overview and detailed installation instructions:

Briefly about the value of supply ventilation from the manufacturer AIR BOX:

DIY installation video tutorial:

An alternative expert opinion on the effectiveness of climate control window valves. Be sure to watch the video before violating the integrity of the inner sealing contour of the window:

Manufacturers claim that supply valves will help to establish a comfortable microclimate, get rid of drafts and condensation on the windows. Good ventilation is the key to sound sleep and excellent well-being for all family members, but one should hardly expect miracles from an inexpensive household device.

Reading 9 min.

The building codes of the past did not imply such tightness of the premises, which can be observed now. Air circulation was largely provided by door and window openings, the density of the porch in which left much to be desired.

A fundamentally different approach to glazing minimizes heat loss and provides excellent sound insulation of rooms. But at the same time, if you do not pay due attention to ventilation, comfortable living in such rooms is difficult to imagine.

Ways to ventilate plastic windows

The most in demand at the moment, and many of their owners faced the problem of controlled ventilation. Consider the common ventilation options for rooms glazed with PVC structures.

micro-ventilation

Another name for this ventilation method is slot ventilation. In fact, this is opening the window in such a way that a gap of several millimeters is formed between the sealing elements of the sash and the frame. Externally, both from the outside of the room and from its inside, the window looks completely closed, which minimizes attempts of unauthorized entry through it.

The micro-ventilation function will only work in units equipped with the appropriate fittings. Its principle of operation is quite simple: to open the sash in this mode, you need to put the handle at an angle of 45˚ between tilt and turn position.

This method of ventilation is more in demand during the cold season, when the use of conventional options will lead to excessive cooling of the room. This is especially true in children's rooms and rooms with a high likelihood of drafts.

Stepped opening

Unlike the previous method, in which the adjustment options are limited to one position, stepped ventilation provides more opportunities for ventilation of the premises. The ventilation gap is adjusted in accordance with external and internal climatic conditions in several positions (from 3 to 5).

As in the case of micro-ventilation, the stepped mode is available if there are special fittings in the unit.

There are two options for it:

All the methods described above require the direct participation of people in the room, which is not always convenient. You can partially automate the ventilation process with the help of special window modules and built-in devices.

Installation of fittings for three-stage micro-ventilation on a plastic window:

self-ventilation

Self-ventilation of plastic windows can be implemented both directly in the window unit and with the help of supply valves mounted in the wall.

Supply wall valves

One of the most effective and relatively easy to install options is to install a ventilation valve in the outer wall of the building. When choosing this method, air enters the room either through mechanical supply, or without it, due to the difference in pressure outside and inside the room.

Structurally, this is a plastic pipe of the appropriate length (slightly larger than the thickness of the wall), the inner cavity of which is covered with noise isolation material. From the outside, the pipe is closed with a two-layer grate to prevent insects, dust and debris from getting inside.

From the side of the room, an adjustable damper is mounted with the possibility of completely blocking the air flow, for example, in case of strong wind. Also, the device is equipped with air filters.

Some more sophisticated models can be equipped with a fan, a heating element, temperature and humidity sensors, and a remote control.

Note! When choosing a supply valve, you should pay attention to the throughput of the device, the presence of a sufficient number of temperature conditions and the possibility of adjustment.

Most elements of wall inlet valves are sold separately, which makes it possible to assemble simple structures on your own.

Supply window valves

Unlike wall analogues, these ventilation elements are mounted directly into the window block. Depending on the design features and the method of ventilation, the following varieties are distinguished:

• With manual adjustment. The valve is installed either on the leaf or on the block frame. In fact, this is an opening closed with decorative grilles on both sides, equipped with a valve, a filter element and a damper for adjusting the air flow.
  Aereco inlet valve is mounted on the window sash

  
  Another modification of the Aereco supply valve

• Automatic valve. The throughput of such devices is electronically controlled, with the help of special sensors that monitor the state of the microclimate in the room and, accordingly, open the damper. This is much more convenient than constantly adjusting manually, but the cost of automatic models is quite high.
  
• Seam valve. The easiest to install and affordable way to ventilate window blocks. Mounted in the sash rebate and outwardly hardly noticeable. Does not require milling grooves or drilling holes - just trim the seal.
  
• slotted valve. Structurally very similar to the version with adjustment. The only difference is that in most models there is no way to control the incoming air flow.

  
  Air-Box Standard valve

• Handle with ventilation. The lower part of the opening handle is made with ventilation holes and is somewhat larger than usual.

  
  Handle with ventilation SK - 201

• Overhead ventilation modules. Most often they are attached to the sash, they have a bulky appearance, but they are quite effective (compared to the above options for window valves).

Pros and cons of supply valves

Pros:

• Ventilation occurs without drafts and foreign pollution from the street;
• Continuous operation provides a continuous supply of fresh air into the room.
• Most devices are easy to use and install.
• Even the most budget models significantly reduce the amount of condensate on window panes and frames.

Minuses:

• At particularly low temperatures, frost may form on the valve;
• Manual modifications require the constant participation of the user, otherwise it will either be cold or (with a large number of people) the freshness of the air will be far from desired;
• Most window shutters partially violate the sound insulation, which causes an increase in noise in the room;
• If there is no general ventilation in the apartment, the effectiveness of the valve is reduced to nothing.

Compact ventilation devices (breathers, ventilators)

Breezers (ventilators) are compact systems for supplying fresh, clean air to rooms.

The supply is carried out either naturally or with the help of a fan. In the first case, quiet, energy-saving operation of the device is guaranteed, but problems with ventilation are possible if there is no difference in external and internal pressure.

Review and feedback on Breezer Tion 3S:

Ventilator with fan will provide proper ventilation, regardless of external climatic conditions, you only need to select the desired mode. In some models, the performance depends on the fan speed, the noise level produced by the device and its power consumption also depend on them.

The devices are equipped with filters of various degrees of purification. The number of elements and the level of filtration depends on the specific model, the most advanced of which are able to purify the air from the smallest dust particles. In addition, filtration at the molecular level is possible (for example, aftertreatment of exhaust gases).

Breezers, unlike many ventilators, are more autonomous. It is enough to set it up once (specify the schedule, set the appropriate operating mode) and it will automatically maintain the desired microclimate in the room.

Prices

Budget Breezer, calculated for 32 m2, costs - 21000 r. Model with performance up to 140 m3/hour – 43000 r.

Supply wall valve will be much cheaper - the cost fluctuates from 1000 r. for a simple device up to 8500 r. for a model with a turbine and a high-quality filtration system.

The cost of a valve mounted on a window without milling - from 350r. Overhead modifications requiring complex installation - up to 4500 r.

Valve mounting options

Mounting the patch valve on a metal-plastic window block is performed as follows:

More details can be seen in the video:

Installing a wall inlet valve in some situations requires special equipment. This primarily concerns the installation of large diameter valves in thick walls. To make a hole, you will need a powerful puncher and a drill of the appropriate diameter and length.

Such a tool is a rarity in the household. In addition, difficulties may arise when working on the upper floors. Otherwise, the installation of the wall valve does not require any professional skills and is carried out according to the attached manual.

The process of installing such valves in an apartment, see our video:

Ventilation devices come in different designs, but they are all small holes in a plastic window through which air from the street enters the frame, passes a small gap there and enters the room.

The valves are adjustable, so the flow will flow in the amount necessary for the owner, and if desired, completely blocked.

Most often used for domestic purposes, but also popular for industrial, retail and office space.

1. The room is ventilated around the clock. Thanks to the installed valve, air from the street enters the apartment. And even in winter, when normal ventilation is not possible, ventilation will provide a constant supply of freshness. Also, you can manually adjust the ventilation intensity or completely block the throughput channels.
2. It is possible to ventilate the room without dust, noise, insects and painful drafts. Fresh air from the street enters a special space inside the frame. Passing through it, the air warms up (this applies to winter time, when it is cold outside) and enters the room without dust and insects.
3. The microclimate of the room improves. Ventilation leads to a decrease in the level of carbon dioxide and humidity. Windows become less likely to fog up and form fungus or other viruses. Thus, the microclimate of housing becomes much better.

Advantages:

1. Ventilation of the room occurs with closed windows, so the penetration of intruders becomes unlikely.
2. Easy to use- set and forget.
3. Keeping warm in the apartment when ventilating.
4. Increases the operating life of the premises, due to the normal level of humidity and the absence of mold or fungus (such problems are especially relevant for balconies and kitchens).

Valve- this is a hole in a plastic window through which air from the street enters the frame, passes a small gap there and enters the room. The orifice dimensions can be adjusted to suit the required flow.

Varieties

There are three types of ventilation valves:

Folded

This is the simplest and most economical option. The influx of fresh air is carried out due to small cuts in the porch. This type practically retains sound insulation, but has a very small throughput, due to which the ventilation will be inferior.

Installation does not require dismantling of plastic windows. Valves of this type are mounted in already installed structures, which is their main advantage.

slotted

This type has a large capacity. Ventilation occurs due to the gap, which is 12–16 mm high and 170–400 mm wide. Outside, the hole is covered with a pass block, which prevents dust and insects from entering.

It is also mounted in installed plastic frames, but is more efficient than the rebate type.

Overhead

Provide the best ventilation, however, have some disadvantages. Firstly, they cannot be installed in a finished plastic structure, since it is necessary to prepare a place on the frame for it in advance. Secondly, they have poor sound and heat insulation.

This type is best used in production shops.

Criterias of choice

In order for the installed ventilation device to bring maximum effect, it is necessary to choose the best option for each case.

Therefore, valves differ in the following characteristics:

1. Air exchange parameters: the inflow must flow in the required volume, when calculating 30 m 3 / hour per person.
2. Noise level: Basically, plastic windows have an indicator of 30-35 dB.
3. Operation in winter: the damper must be adequately insulated to prevent icing and not interfere with ventilation.
4. Adjustment option: automatic control, manual and mixed is possible.
5. Mounting method: it is necessary to choose whether the valve will be installed in old windows or new double-glazed windows should be ordered with ventilation calculation?

Attention! Do not consider options without the ability to adjust the level of air exchange. As practice shows, this parameter is necessary.

Types of structures

The most popular at the moment are two options: Aereco and Air-Box. Consider their features and principle of operation.

Aereco

1. EMM. The most common option, which is equipped with hygroregulation technology. The built-in sensor regulates the width of the opening depending on the humidity of the room. This type of construction is mounted vertically or at an angle. Available in three colors: oak, teak and white. Throughput - 5–35 m 3 / hour.
2. EHA2. It is also equipped with a sensor, but has a large air flow - 5-50 m3 / h and more advanced acoustic capabilities (42 dB, versus the usual 37).

Air box

The Russian company Mabitek also released a line of ventilation valves.

They are installed on blocks of any design and are almost invisible:

1. standard. This is a standard version, which consists of two parts: an external one, which collects air, and an internal one, which supplies it to the room. When the ventilation is running, the flaps of the damper open and allow about 6 m3/h to pass through.
2. comfort. Noise-proof option, which involves installation in a window profile or in sealing rubber, which is much easier and faster.
3. Comfort S. Assumed for blind windows. Through holes are drilled, due to which direct blowing occurs.

Air-Box is the leader among other valves due to its economical cost, efficiency, small size and ease of installation.

Mounting

Virtually all companies that sell valves offer their installation services. Their cost is low, but the amount of work is small. We suggest that you read the instructions for self-assembly. For example, we will tell you how to install a slot-type ventilation device.

Required materials and tools:

• construction knife;
• screwdriver;
• ruler;
• valve;
• seal and plugs;

Walkthrough:

1. Remove all unnecessary from the windowsill.
2. open window.
3. On top sealing rubber measure the length of the purchased valve.
4. With a knife make two cuts and remove the intermediate piece.
5. Install instead new sealing rubber.
6. measure distance from the edge of the window to the beginning of the new seal.
7. Set aside the same distance on the upper sash of an open window and make an incision in the seal.
8. Measure the length of the future valve on the flap and make a second cut.
9. Remove the intermediate piece.
10. Instead of the old seal install three plugs wide side up. They should move freely on the side of the window.
11. Install plugs at a distance corresponding to the valve mountings.
12. Peel off the strip double-sided adhesive tape on the valve and stick it to the window, pressing it tightly against the installed plugs.
13. Screw screws in fasteners.
14. Glue shorter seals between fixtures.

Ways of regulation

Depending on the structure and mechanism, the ventilation device can regulate the level of air exchange or block it. This process can be automated or manual.

The first option is equipped with a hygroregulation (moisture sensitivity) sensor, according to which the throughput changes. If the room has a high level of humidity, the width of the hole will be maximum.

Otherwise, when the room is empty, the air supply is cut off. In the manual version, you have to constantly adjust the width of the section for a comfortable stay. The only thing that this option is designed for is a restriction in case of strong gusts of wind.

Another and very important advantage of ventilation valves is easy maintenance. For full-fledged work, it is enough to clean the surface of dirt once a year. This is the necessary service.

Price and reviews

The ventilation valve is only an addition to a plastic window, so its cost should not exceed the price of a conventional double-glazed window. On average, the best option is 20-40 USD. e.

Reviews:

Ekaterina:

In the summer, we open the windows at night so that the children can sleep in the fresh air. In winter, this is no longer possible. Even if you ventilate the room right before going to bed, after 30-40 minutes it will be stuffy again. That is why two valves were installed. Now it's fresh all day, and it doesn't blow at all. In general, the best option for a child's room.

Igor:

When ordering windows for the whole house, they asked the manager about ventilation. She advised not to install valves, since with our climate they can freeze in winter and not close. They are more suitable for Europe than for us.

Alexander:

We bought an apartment where developers used windows with ventilation. Previously, we did not know about their existence, so we would hardly have ordered. We've been using it for two years now and we're happy with it.

In general, if you are a fan of freshness and regularly ventilate the room, ventilation valves are made just for you.
