Probably, many of us have come across a situation where the plastic window does not close from the ventilation mode, or the ventilation does not take place with the intensity that we need. In general, the issue of providing ventilation in the room where plastic windows are installed is quite interesting and extensive.

Therefore, here I will share the most important information that will be useful not only for craftsmen, but also for ordinary owners of PVC structures.

Ventilation methods

Method 1. Standard ventilation

So, if you have a plastic window installed, then the easiest way to ventilate the room is to open the sash. Modern PVC structures have two opening modes:

pivoting - the sash completely opens the opening, turning on both hinges;
flap - the sash tilts into the room. In this case, the upper corner comes out of the hinge and is held by a special piece of fittings.

In fact, the sash can also move up or to the side, but such systems are almost never found in our country. This is due to the fact that the sliding mechanism cannot provide sufficient tightness and pressing the sash to the frame, therefore the heat loss through such a window will be very large. In general, the climate is not favorable.

With a rotary opening, the air exchange is very intensive, therefore it is used mainly for "volley ventilation". Usually, however, they are limited to the folding mode:

The sash is installed in the closed position.
We turn the handle up and at the same time pull it towards ourselves.
The sash tilts, creating a wide enough gap through which fresh air enters the room.

It should be noted that not all windows have the ability to set the sash in the tilting position - a separate piece of hardware is responsible for its implementation, which is placed in the upper part of the strapping.

That is why it is better to think in advance whether you need this function: in principle, it is possible to remake a plastic window for ventilation, but this is associated with additional costs, and you are unlikely to cope with this task on your own.

Hinged ventilation has one significant drawback - sometimes the plastic window does not open for ventilation or the sash, as they say, "falls out", hanging on one lower hinge. This situation is very common, the reasons for it can be eliminated quite simply, and I will talk about this in a separate section.

Method 2. Microventilation

Traditional ventilation by installing the sash in the tilt position is very effective, but it also has disadvantages. So, in winter, an intense air flow leads to a rapid cooling of the room. In addition, you should not leave, leaving the sash ajar - attackers will open such a window in just a few seconds.

In either case, there is an alternative - slot ventilation or microventilation:

Air access to the room is provided due to the fact that when the handle is turned 450 upwards, the sash moves away from the frame by literally a few millimeters.
A small metal part is responsible for this, which is built into the fittings and engages with its elements, which ensure the movement of the sash on the hinges.
When the micro ventilation mode is set, the window looks tightly closed from the outside. At the same time, air continues to flow regularly - albeit in small portions, but without leading to hypothermia of the room.

Method 3. Stepped opening

Normal opening is fine, micro ventilation is fine, but sometimes both are not suitable. That is why many manufacturers of PVC structures provide windows with either on-off opening adjusters or special devices that allow you to adjust the tilt angle of the flap.

The opening regulator is located at the top of the frame on the inside and is a lever of variable length:

If you open the regulator completely, then the sash will open as wide as possible, providing an intensive flow of air.
If you shorten the lever of the regulator, then the sash becomes on the so-called winter ventilation - the gap is 1 - 2 cm, which makes it possible to minimize the hypothermia of the room.

An example of such a device is the "Winter - Summer" system in the Siegenia aubi favorit fittings.

Staggered opening also works quite simply:

The so-called "comb" is responsible for the functioning of the system - a small part that is built into the fittings.
When opening the window to tilt, we turn the handle to an angle of 450 (as when setting for micro-ventilation).
In this case, the handle goes through four or five positions, each of which has its own opening width of the sash. By installing it in the chosen position, we will provide the required ventilation intensity.

The features of most hardware systems do not allow the installation of both micro-ventilation and a step-by-step mechanism at the same time. However, as a rule, the extreme position of stepped ventilation approximately corresponds to the thinnest slot, therefore these systems are largely interchangeable.

In addition, to implement the function of step-by-step opening, you can install the simplest mechanism - a plastic comb. This part is a toothed rack, which is placed on the frame and, when opened, engages with a counter protrusion mounted on the sash (attached under the handle). Outwardly, of course, it does not look as neat as the built-in step ventilation mechanism, but it performs its function.

The plus is the fact that the comb can be put on any window - if only its sash opens in a tilt / turn position. At the same time, a master is not required for installation: there you just need to tighten three or four self-tapping screws.

Ventilation valves as a special tool for air exchange

The principle of operation of devices and their advantages

If you do not want to face problems like "window jammed", "blowing from an open opening", then instead of traditional ventilation, you can install a special ventilation valve:

A window vent valve is a device that is usually mounted at the top of the frame and closes off the through hole.
Inside the valve there is a mechanism that regulates the intensity of air flow into the room.
The simplest designs are provided with mechanical adjustment: if we need, we open the valve, if not, we close it, completely or almost completely blocking the air exchange.
More complex valves operate due to a hygroscopic sensor: the higher the air humidity in the room, the more intensive the ventilation is.

All valves of this type provide only fresh air supply. For their normal functioning, it is very important that the hood works normally in the room - natural or forced.

These devices have several obvious advantages:

You can set the ventilation intensity once, and adjust it only when the weather conditions change.
When ventilated, the window remains closed, so the level of protection against unauthorized entry is not reduced.

Air enters the room gradually, and in small volumes. In addition, an air vent is located at the top of the room. Therefore, cold air masses of air are mixed with warm air under (pure physics!) And the apartment does not cool down as much as during normal ventilation.

The main disadvantage is the price of the devices.... So, the VENTAIR THERMO valve will cost us about 1800 rubles, and the simplest model from AERECO (with humidity regulation) - 2 - 2.5 thousand rubles.

How to install a valve on a window

The ventilation valves themselves are expensive, but in addition to buying the device, we will also have to spend money on installing it. However, if you have dexterity, it is quite possible to cope with your own hands.

I carry out the installation of the supply valves according to the following scheme:

The sash is removed from the hinges and installed vertically on a flat surface.
From the upper part of the sash I remove the elements of the fittings - they will interfere with the work.

I attach the mounting plate - a part that is used to secure the valve - to the flap protrusion from the outside, after which I mark the size and position of the ventilation holes with a marker.
Using a drill, I drill 4-5 holes according to the marking. Then, with a thin saw or jigsaw, I connect the holes, forming a long groove or two grooves, separated by a thin partition.

I fix the mounting plate on the sash with self-tapping screws. Plank and sash joint using moisture resistant silicone.

So that during intensive ventilation the air does not whistle, I also cover the opened chambers in the window profile with silicone.

I repeat the operations on the frame, but instead of a mounting plate, I install a visor outside. The design of the visor can be very different, ranging from a simple canopy to a complex system with an acoustic curtain that reduces the volume of the transmitted sound.
I put the dismantled fittings back in place and hang the sash on the hinges.

The valve itself is snapped onto the mountings of the mounting plate in such a way that the ventilation hole is directed upward at an angle.
Using the slider or knob, I regulate the ventilation intensity, choosing the optimal mode.

This manual is for informational purposes only, since the mounting technology may differ from one valve to another (for example, there are models that are mounted without a mounting plate, directly to the window). But in any case, following it, you will be able to install a device for supplying ventilation through a plastic window.

Solving the problem with a jammed sash

Talking about ventilation through windows, one cannot get around the problems associated with this process. So, very often people ask what to do if a plastic window is stuck in the ventilation mode?

The reason for this situation is as follows: if you try to switch the sash to tilt mode from the pivot mode without closing it tightly enough, then the lower corner may simply not be fixed. As a result, the sash hangs on one hinge and an opening limiting lever.

The problem is solved as follows:

Raise the jammed sash and press it against the frame, returning it to the closed position.
Separately press the bottom corner of the sash, which is opposite the bottom hinge.
We turn the knob, moving it to the “closed” position - ie. lever down.

If the handle is stuck, i.e. it does not turn, there is no need to act “on force” - just break the lever. This situation most often occurs when the sash is skewed, so you should first try to carefully eliminate the skew. To do this, it is usually enough to slightly displace the sash, applying force to the overlay, and after opening, adjust the position of the hinges.

After that, we repeat the attempt to open in the ventilation mode - everything should work out!

To avoid such a development of events, it is worth installing such a detail as an erroneous opening blocker. It prevents any attempt to move the sash to the pivot position until it is fully closed and all hinges are engaged.

Sometimes the reason that the plastic window does not open well for ventilation is also the wear of the fittings. In this case, the optimal solution would be to clean it from dirt (a mixture of dust and oil often forms a dense crust on the pins and counterparts), followed by lubrication.

After lubrication, it is worth turning the handle several times, believing how freely the window opens.

Well, if this does not help, then here, probably, only a specialist in fittings will help - therefore, it is worth contacting the master.

Conclusion

If in your house or apartment the window for ventilation never opens, you should not be surprised if you feel bad. Ventilation is essential to provide fresh air.

And modern metal-plastic structures have many mechanisms that can provide this ventilation. The video in this article will help you understand their assortment. , and all your questions regarding window ventilation, I will answer here in the comments or on the forum.

The installation of sealed window structures entails a deterioration in the microclimate of the room: humidity rises, there is a lack of oxygen and air staleness. Problems can be easily solved by placing a supply valve on plastic windows - the device normalizes natural ventilation and stabilizes air exchange.

We will tell you how to choose the right ventilator to ensure the supply of fresh air to rooms with plastic window frames. We have described in detail the popular models of the device tested in practice. For independent home craftsmen, we provide detailed installation instructions.

The basis of a normal indoor microclimate is the presence of an effective one.

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

The old imperfect designs did the job efficiently, providing sufficient airflow even in winter. Lack of wooden frames - poor noise and heat insulation

An attempt to restore air circulation by opening a window in ventilation mode cannot be considered a good solution for the following reasons:

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

Several manufacturers of window systems have taken into account the consequences of complete tightness and have improved metal-plastic structures.

Violation of air exchange negatively affects the health and life of people. Condensation appears on the windows, slopes and walls are covered with mold - the concentration of toxic substances increases

Special ventilation fittings:

ventilated profiles;
opening stops;
partially breathable seals;
glazing beads with a regulating valve.

A supply valve is used to ensure the flow of air through the previously installed window.

Supply ventilation on plastic windows allows you to constantly maintain a favorable microclimate in the room. We will discuss this aspect in detail below.

Plastic windows provide almost complete sealing of the room. In the harsh 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 due to severe frosts. Lack of fresh air is fraught with many problems:

Misting windows.
The appearance of fungus and mold on the slopes.
Musty air. This creates discomfort in the room.
Young children may develop allergic reactions.

Additional ventilation in a room with plastic windows is provided by installing special valves. They have various design features, but their main purpose is to let outside 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, set the flaps to summer mode - in this case, the frames will not close too tightly, which will allow oxygen to penetrate into the room.

When is the organization of additional air circulation necessary:

If small children live in the house. As mentioned, lack of oxygen can be detrimental to their health.
Indoors with many plants. Without oxygen, they will simply die out.
When the house is warmed up with convectors or oil radiators. Such heaters dry the air monstrously.
In production. In workshops (if they are associated with toxic substances), it is necessary to organize the maximum flow of fresh air.

All known varieties

A ventilation valve for plastic windows is only a seemingly simple device. It is subdivided into several varieties, which have significant design differences. You should know them in order to find the best option.

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

Low cost.
There is no need to dismantle installed PVC windows.
It guarantees the preservation of the soundproof properties of the glass unit.
High speed and ease of installation.
The possibility of automation.

Among all the advantages, there is one, but a very important disadvantage - weak bandwidth. Because of this, folded ventilation with closed windows is ineffective.

Slotted

Fresh air enters the room through special ducts. Usually they have a size in the range of 160-400 by 10-16 mm. As a rule, such a valve is equipped with two blocks - an inlet and a regulating one. On more advanced models, it is one (universal). Technology advantages:

Absolute protection from external factors (precipitation, insects). This is ensured by the presence of a regulating unit.
High (in our case, medium) transmitting capacity.
Can be used without dismantling the glass unit.

There is only one serious disadvantage in this case - a relatively complex installation. However, some models are devoid of even such a drawback (more on that later). Therefore, this category is the most popular now.

Overhead

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

The thermal insulation properties of windows are seriously reduced.
Soundproofing is practically zero.
It is possible to install such a ventilation valve only before the installation of a double-glazed window. In particular, it is necessary to adjust the size of the opening.

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

Market leaders - Aereco and Air-box

The domestic valve market was 90% occupied by two manufacturers Aereco (France) and Air-box (Russia). You should be aware of the features of their products:

High quality and practical option

Valves from Aereko are a cover 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 in place, then the installation can also be done. To do this, you need to make a little drilling of the frames.

The device consists of 8 (16) moisture-sensitive plates. Depending on the humidity level, they can open or close the damper. Moreover, they do not need power supply for their work. 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 it is extremely difficult to mill concrete structures. From the point of view of its qualities, this manufacturer looks like the best analogue on the market. However, it has an important drawback - a high price (from 2,500 thousand rubles).

Cheaper analog

The Russian manufacturer air-box makes its products much simpler, which, at the same time, almost does not lag behind in efficiency from their more expensive "counterparts". Such models allow outside air to penetrate through the space between the frame and the sash. It leaks out thanks to the replacement of the standard seal. To control the air flow, you need to move the regulator knob.

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 a simpler installation technique. Air-boxes are installed in two ways - by means of milling the frame (as in the previous manufacturer) and by replacing the seal (which will be discussed below).

Possible installation options

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

The most difficult method is to adjust the size of the opening.

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 glass unit is removed.
The opening widens by the size of the lining.
The double-glazed window is installed back.
An overlay is installed in the resulting gap.
The cracks are covered with cement mortar (or something similar).

The technique looks deadly laborious and unreasonable. Therefore, no one does work in this order, because it is fraught with cosmic expenditures of effort, time and money. It is necessary to take care of additional ventilation in advance, that is, before installing a double-glazed window.

The most thoughtful people, when ordering PVC windows, immediately plan to install an additional air flow. For this, the opening is made slightly wider than the double-glazed unit requires. This technique is the most effective, and most importantly rational.

Assembly instructions for Aereco models

However, what to do if the glass unit is already installed? Aereco models are installed using a simpler method. It consists in the following:

A place for installing the channel is selected. If possible, this should be the least visible area.

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

Then the markup is done.
We fasten the bar to the chosen place using special self-tapping screws for PVC structures.
We mark the location of the technological grooves on the vestibule.
We remove the bar. Using a drill and an electric jigsaw, we saw holes in the sash and the frame itself.
Set the bar again.
We fix the valve with special latches.

This procedure is relatively time consuming. In addition, it requires special tools that everyone has. Another factor is that a person without proper experience will not be able to do the job accurately. Conclusion - it is better to entrust the installation of such a device to a specialist.

Air-box - installation hassle-free

There is another technique that anyone can handle. The air-box manufacturer has created a model that can be assembled without the use of tools. The kit includes a special seal and PVC screws. The work is done in the following sequence:

We select the proposed installation location.
We cut off the standard seal (which is located on the sash) in this place.
We insert a new one (from the kit).
Remove the protective film from the valve.
We fix it in the place where the new seal is installed using special latches.
We close the flaps and make a mark on the frame along the length of the valve.
We cut off the existing seal in this place and install a new one in its place (the same one from the kit).

If something turned out to be incomprehensible to you, you can watch the video from the manufacturer itself. It will allow you to clearly understand everything.

Systems on the market can be divided into three categories.

Slotted

The device is mounted in the upper part of the opening sash or vertical impost. For installation, you have to dismantle part of the fittings and mill holes in the metal-plastic profile. If you are not confident in your abilities, it is better to entrust the work to professionals.

Structurally, the system consists of two blocks. One is mounted from the side of the street. It serves both as an air intake and a visor that protects the channel from precipitation. The second block is placed on the inside. It contains a mechanism that regulates the intensity of ventilation.

The main advantage of this design is its high throughput. The length of the ventilation duct varies within 170-400 mm, and the width is 12-16 mm. This is enough to organize the microclimate in large rooms.

Overhead

They are integrated into the window profile at the stage of frame manufacturing. It will not be possible to establish them after the fact. In everyday life, such systems are not used due to the excessively large bandwidth. They are usually used for ventilation of large offices and sales areas.

Products are indispensable in pavilions with solid glazing, when it is not possible to make ventilation ducts in load-bearing structures. Unlike wall models, their disadvantage is low sound and thermal insulation.

Folded

They became popular due to their low cost and ease of installation. You can install them yourself in just half an hour.

The product is placed on the top of the sash in a gap. Fresh air enters the room through a small gap in the seal. The design is very simple, but it provides for the ability to adjust the air flow.

It is useless to install such devices in a hall or large living room. They will not provide adequate air exchange. They are best used in a kitchen or small bedroom.

Methods for adjusting valves on PVC windows

Manual

A handle or a slider is provided on the body of such devices. Its movement changes the position of the damper, and hence the intensity of the air flow. Such designs are reliable and durable. There is practically nothing to break in them. However, there are a number of disadvantages:

Limited access. The controls are located at the top of the sash. Every time you need to change the position of the flap, you have to take a chair. In some models, this problem is solved by installing a lace, like in blinds.
Static. It is very difficult to maintain a constant microclimate with their help. To achieve a comfortable environment, you have to change the position of the shutter depending on the weather. It is not always possible to find the right mode.

Automatic

Such products have a number of advantages:

Maintain a constant microclimate. The device independently creates preset comfortable temperature and humidity. The air flow rate is adjusted based on the readings of the sensors.
Autonomous. The product works without electronic components. It does not need mains power or batteries. The flap is moved by nylon belts. Depending on the pressure, they change their length and, accordingly, the position of the damper.
Profitability. The supply of fresh air increases with increasing humidity, for example when there are many people in the house or when laundry is drying. In a relaxed environment, the device does not overcool the house, which reduces heating costs.

Pros and cons of supply ventilation valves

Advantages:

Household appliances are simple and reliable. You can install them yourself.
The vent cover removes excess moisture from the most favorable place for its formation - the border of the temperature difference. If there was perspiration or condensation on the double-glazed windows, the number of drops decreases or they disappear altogether.
There are no drafts in the room, as with micro-ventilation or full opening of the window. This means that the risk of colds is reduced.
Air exchange between the apartment and the street takes place continuously. You breathe fresh air all day long, not just when airing out.

Disadvantages:

In severe frosts, budget models can freeze over.
The vast majority of products do not have filter elements. Because of this, dust and foreign odors enter the house.
Only expensive models can cope with full-fledged microclimate control. In the budget, you have to independently monitor the temperature and humidity in the house - constantly changing the position of the damper depending on weather conditions.

How to choose a supply valve for plastic windows

Let's list the most important criteria that you need to pay attention to when choosing:

Noisiness. When air masses pass through a restricted opening at high speed, noise is generated. A comfortable sound level is in the range of 30-40 decibels. Models in which a narrow long gap forms on the minimum vestibule can whistle in strong winds. If in the working position the valve does not fit snugly against, it may rattle.
Performance. Directly depends on the nominal diameter of the ventilation holes. The larger the area of the channels, the more fresh air enters the house through them. When choosing a specific device, you need to build on the area of the room and the number of residents. The productivity of different devices varies in the range from 6 to 150 m3 / h. It is better to choose a device not exactly according to its parameters, but with a margin of 1.5-2 times.
Air preheating. In classic models, cold air masses are warmed up by a warm convection flow from a radiator. In northern areas, this may not be enough. Then you need to select electrically heated equipment.
Filter type. In structures that are mounted on the sash, they are absent. Models integrated into the frame can be equipped with filter elements. When using them, dust from the street does not get into the room. But the filter must be constantly cleaned, otherwise the performance of the device will greatly decrease.
Installation method. There are universal models that can be integrated into the window profile of any manufacturer. Some of them you can install yourself. But some of the structures must be mounted at the stage of manufacturing the frame.
Price. Each of the options listed above affects the cost. If you are too demanding on the microclimate, it is worth comparing window devices with other options for climatic products.

How to install a supply valve on plastic windows with your own hands

We carry out the work in the following sequence:

We mark the middle of the window sash.
We fasten a metal template or a plastic mounting plate.
With a drill with a diameter of 4-5 mm, we make centering holes along the edges.
Using the template, mark the contour of the future slots and remove it.
We drill holes with a 10 mm drill.
With a jigsaw, a renovator or a router, we cut the grooves between the holes.
With the window closed, transfer the dimensions of the holes to the frame.
We install the template on the frame profile and repeat all the operations for milling the grooves. For the convenience of work, we temporarily take out the sealing gum.
We fasten the mounting plate from the inside.
We install on her an element with a valve that regulates air exchange.
We fasten the protective visor from the outside.

You can clearly see the installation process in the video.

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 providing the internal space with sufficient fresh air. The only correct solution is to install a supply valve on plastic windows. What kind of products are these, and what is their purpose?

Do you need air inlets at all?

Plastic windows have a lot of obvious advantages. They were appreciated not only by the owners of city apartments, but also by the owners of country cottages. But with all its "pluses", visually beautiful solutions de facto worsen the microclimate of the dwelling. Installation of supply valves on PVC windows is the most affordable and simple way to normalize the temperature and humidity conditions, leveling the risk of mold and mildew formation.

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 supply valves on windows for a number of reasons:

in the process of its functioning, any heat losses are excluded, the level of sound insulation remains at the original level;
unlike traditional ventilation, drafts do not occur;
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 do you need supply valves

Design features and nuances of functioning

Competent 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, both at the sash and at the frame. It is replaced with an additional layer of sealant and an air inlet, to which the role of passive ventilation is delegated.

The solutions installed in this way allow warm air to be removed outside and fresh oxygen is 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. In the sultry heat, ventilation products are activated thanks to forced draft.

A valve for a plastic window includes a number of elements:

outer structure of the air intake(mounted only 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 duct- 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, it is one of the most complex elements of the system, which includes: a control mechanism (for adjusting the air flow), a filter grate 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 cracks in the floor, in the interior doors);
tightness of the front door;
outside the window the temperature regime is not lower than + 5 ° С.

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

Transfer of "Miracle of Technology" to NTV, about Aereco supply valves

A wide range of exhaust solutions for PVC windows is on sale. As for the differences between specific models, it is customary to consider them according to a number of criteria.

Varieties of air inlets

Depending on the prevailing design material:

metal;
wooden;
plastic.

Fresh air intake method inside the room:

Overhead solutions... Ventilation valve for plastic windows with high efficiency. Its key feature is the need to "fit" the frame and glass unit design to the exhaust device. Such products cannot be built into a finished window. The main area of application is warehouse facilities, industrial complexes.

Supply-slotted structures... Air is drawn in through a 16 cm slot. Inside the room there is a special regulating block, and outside there is an inlet block that prevents the penetration of insects, small particles and precipitation. There is no need to dismantle the window for installation. The product is characterized by a sufficiently high performance.

Folded products... One of the most affordable window varieties. The supply of fresh oxygen is carried out through small cutouts located in the vestibule. The solutions are distinguished by good sound insulation, low bandwidth 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 without compromising the appearance of the opening itself.

Step-by-step instructions for installing a ventilation valve

Let us dwell in more detail on the nuances of installing a valve with our 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;
medium-length screwdriver;
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 35 cm segment. Special fasteners on self-tapping screws are used to fix the structure.

Stage 1 . Localization of the installation site... It is customary to place window supply valves in the upper part of the sash. Experts recommend marking a place in the middle of the structure, and then attach a template to it and circle it around.

Stage 2 . Removing the seal... In the marked 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... Insert 3 fixing plugs into the free groove. Their main purpose is to mount the valve body on the base of the leaf. One dowel is displaced exactly in the middle, and the other 2 are placed along the edges.

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

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

Stage 7 . Removing the old frame seal... In order for the ventilation device to function properly, it must 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 must be at least 35 cm. Dismantle the old seal and then replace it with a new one.

The seal in the frame is as 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 in. The window will remain functional.

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

The device considered 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 the help of specialists. Installation features depend on the configuration, design and specific valve model.
