Rebated inlet valve. Do-it-yourself supply valve for plastic windows. Advantages of supply ventilation using valves

Ventilation valve for plastic windows allows you to solve many problems: drafts, stuffiness in the room, condensation on the glass, which leads to mold. The main advantage of modern window blocks made of PVC profile– tightness turns into a disadvantage under certain conditions: when you need to ventilate the room, but you can’t open the windows for various reasons ( winter time years, a sick child, etc.).

Ventilation modes are not always suitable: either drafts occur, or the gap between the frame and sash profile is too thin, which is why the required volumes of fresh air do not enter the room.

folded;
slotted;
invoices.

Rebated valve

The first two options are installed on windows that are already in use. Installation in in this case really do it yourself. The slot valve is equipped with inlet and control blocks; some models have a universal ventilation unit– combined option.

Protection is installed on the outside of the slot ( mosquito net) from litter and insects. For ventilation, a gap is provided with a length of 170 to 400 mm and a width of no more than 16 mm.

The rebate valve creates small gaps in the window sash. This operating principle does not provide high efficiency, but the sound insulation of the window is not compromised. There is also a more effective design - an invoice. However this option difficult to install with your own hands.

In addition, its efficiency is quite high, which can become an obstacle when creating a normal microclimate in a small home. Therefore, such designs are more often used in production.

Ventilation wall view

Valves are functioning supply ventilation based on the principle of pressure differences. In this case, colder air is drawn into the room, and flows out of the valve warm air. This is how passive ventilation works, so its effectiveness drops when the outside temperature rises above +5 degrees. To increase exhaust draft in the warm season, it is recommended to use a forced ventilation system.

Design selection

If condensation forms on the windows, the room is stuffy and you have to ventilate frequently, you should adjust the fittings and check the seal. If no structural violations are identified, you can consider installing a supply valve on the window yourself.

Main selection criteria:

operating efficiency, which is determined by the parameters of the device and the number of people living in the apartment, for example, a sufficient air exchange rate in a room for one person can be provided by an influx of 30 cubic meters. m/h;
the noise level during valve operation should not exceed 35 dB;
To prevent the valve from icing up during the cold season, the design must include a “thermal break” made of plastic; it is installed between the inner and outer surfaces of the valve body;
type of construction: slotted, rebated - these are the main options that can be easily installed on the window with your own hands;
control method: automatic, manual or combined control.

The most popular designs: Aereco, Air-Box (Comfort, Comfort-S), Regel-Air. Each of the options has its own advantages, but almost all of them are easy to install with your own hands, except for the Comfort-S version, which is designed for a fixed window and is mounted by milling in the upper part of the profile. The Comfort model represents a group of rebate-type products.

Aereco products presented different options: jet flow in an oblique and straight direction. In addition, these valves are characterized by wide functionality, since in addition to their main task, they provide a normal level of humidity in the room thanks to the hygrocontrol function. Regel-Air valves represent a group of rebated designs. Their feature is a movable plastic feather, responsible for regulating the air flow.

Installation

To avoid problems during installation, it is recommended to select certain designs: seam, slotted. The window should be cleared of foreign objects and the curtains should be removed. For installation in a window sash, it is necessary to cut off part of the sealing cord on the frame and sash.

This can be easily done with your own hands using a stationery knife. The valve itself is attached using dowels to the window sash.

Inlet valve installation steps

To install the rebated structure, you will need 3 self-tapping screws; a sealant, which is included in the kit, is placed between them. Usually a sufficient amount of material is provided by the manufacturer. The valve is attached to the window profile using self-tapping screws.

Care and maintenance

Considering that dust enters the room along with the air flow, it is necessary to periodically clean the ventilation device. It is enough to do this once a year. Wipe with a soft cloth plastic surface and seal. Adjusting the mechanism is preferable because a design characterized by constant air flow parameters does not provide optimal conditions in room.

The best option is an automatic device; such models have hygroregulation sensors. The principle of their operation is based on monitoring the air humidity in the room, in accordance with this, the flow channel narrows or expands.

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

Thus, installing a supply valve can significantly improve the microclimate in the room. If you plan to install it yourself, it is recommended to choose a slot or seam type model. Moreover, the second option is easier to implement, since for the slotted type it is necessary to make an even slot in the profile. Given that correct installation you can avoid a number of problems: condensation on windows, drafts, ineffective air exchange in the room.

An important step in any apartment or house will be the replacement of old wooden windows plastic. The change will be so dramatic that you will only think about one thing – why didn’t you do this earlier. The design will significantly reduce heat consumption, significantly reduce street noise, and in hot weather will prevent the room from getting too hot.

But such tightness can be twofold; in particular, it will disrupt the ventilation in the apartment or house.

This may seem strange, but when designing houses in Soviet times, the gaps between frames and main walls were also taken into account as the inflow and outflow of air masses.

That's why ventilation ducts premises of those years today cannot cope with the increased load on them. Today we will tell you about what forced ventilation for plastic windows is and its types.

Removing moisture from the room

Most residential buildings are equipped with the cheapest and simple systems ventilation. They consist of a primitive hood in the kitchen or bathroom, and the air flow is provided by the cracks in the door and window openings.

This option works quite successfully in homes with ordinary wooden boxes, providing the required 30m 3 /hour of air per person, according to the standards. If you install plastic windows and put seals on the doors, the air flow will simply disappear.

This will contribute to disruption of the room microclimate:

humidity will increase;
the rooms will begin to become stuffy;
discomfort and a feeling of lack of fresh air may appear.

A “reverse outflow” may even occur in the ventilation shaft due to a shortage of atmospheric air masses, i.e. There will be a flow of air from the apartment to the outside. As a result, in apartment building odors from neighboring apartments will begin to enter yours.

Ventilation for plastic windows has its own characteristics. For example, many users will notice that in addition to the draft-free system, they will have many other problems, in particular, stuffiness and fogging of the windows.

After complaints to the manufacturer, a recommendation will be given to keep the doors in ventilation mode almost constantly. But then what is the advantage of the system?

Types of ventilation

Ask about their design in more detail and find out:

is there a window;
whether there is a “comb” on the sash or not. The price of the device is small, but the benefits from it are quite significant;
does it have a ventilation valve;
She can self-ventilate.

Let's look at them below:

Comb

The device makes it possible to adjust the sash in certain positions. It's a little different than usual folding mechanism. It makes it possible to set the opening width of the sash in several intermediate positions.

Window

A traditional option for sash window layout.
Guarantees normal ventilation.
The air enters the upper part of the room, mixes with what is already in the room and is further distributed throughout its entire volume.

The main disadvantage is that due to the complexity of the design, the cost of the window increases. In addition, the amount of luminous flux decreases, albeit slightly.

Self-ventilated window

A special profile is used, which has holes in the lower outer and upper inner parts.
This ensures air flow into the upper half of the room.
The window design has a special chamber through which air flows, heats up and enters the room.

Restrictions on use - it is not recommended to install on upper floors wider, and therefore more expensive profile. In this case, insufficient draft will not be able to ensure the supply of air in the required volume. And in hot weather, the system will not be able to fully operate due to the very physics of the convection process.

Window ventilation valves

To maintain a microclimate, not only nearby must be multifunctional. Below we consider their main parameters that characterize the class of the device:

The installation method offers us two options:

replacing the old double-glazed window with a new one, but with smaller dimensions, in order to install a ventilation valve in the resulting space;
placement of the valve in the upper binding of one of the window sashes.

The first method has disadvantages - the luminous flux decreases and financial costs increase.

Control – automatic or manual. We recommend not to consider options with valves that cannot be adjusted. Looks preferable for the price manual method control, which makes it possible to regulate the air supply and save heat. Automatic mode allows you to maintain the selected temperature and humidity in the room.

Tip: if necessary, you can combine both modes, for which a combined control system is installed.

Air exchange rates– must ensure the air inflow and outflow change in the room at a level of at least 30 m 3 /hour per person.

Sound absorption level. Modern design windows allow you to dampen noise by 30-35 dB, so the instructions require installing a ventilation valve with the same technical capabilities.

Operation in winter conditions can be difficult, since it is difficult to predict in advance whether condensation or ice will appear in conditions low temperatures. This still depends on the characteristics of the air indoors and outdoors, its flow parameters, housing material and others.

We suggest that you do the following to eliminate some “risk factors”:

ensure sufficient thermal insulation of the valve by turning Special attention to the part located outside the premises;
install a plastic "thermal break" if a metal housing is used.

The valve itself is a complex device, so its average cost can reach $40-60.

Conclusion

Effective operation of the considered options can only occur if there is properly functioning ventilation. Although the proposed methods help to ensure normal air exchange in the room, there are other factors that can influence it ().

Supply ventilation to plastic windows allows you to constantly maintain a favorable microclimate in the room. We will talk about 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 can be solved simply by ventilation, but in winter such a measure is impossible due to severe frosts. Lack of fresh air is fraught with many problems:

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

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

Tip: Most windows can be adjusted to close tightly. In the warm season, set the doors to summer mode - in this case, the frames will not close too tightly, which will allow oxygen to penetrate into the room.

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

If there are small children living in the house. As already mentioned, lack of oxygen can have a detrimental effect on their health.
In rooms with many plants. Without oxygen they will simply die out.
When the house is heated using convectors or oil radiators. Such heaters dry out the air monstrously.
In production. In workshops (if they are associated with toxic substances) it is necessary to organize a maximum flow of fresh air.

All known varieties

A ventilation valve for plastic windows is only a simple device at first glance. It is divided into several varieties, which have significant design differences. You need to know them in order to choose best option.

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

Low cost.
No need to dismantle PVC installed window.
Guarantees the preservation of the soundproofing properties of the glass unit.
High speed and ease of installation.
Possibility of automation.

Among all the advantages, there is one, but very important disadvantage - weak throughput. Because of this, rebate ventilation with closed windows has low efficiency.

Slotted

Fresh air enters the room thanks to special channels. They usually have a size in the range of 160-400 by 10-16 mm. As a rule, such a valve is equipped with two blocks - inlet and control. On more advanced models there is only one (universal). Advantages of the technology:

Absolute protection from external factors (precipitation, insects). This is ensured by the presence of a control unit.
High (in our case average) throughput.
Can be used without removing the glass unit.

In this case, only one serious disadvantage can be found - relatively complex installation. However, some models do not even have this drawback (more on this later). Therefore, this category is the most popular now.

Invoices

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.
Sound insulation is reduced to almost zero.
Such a supply ventilation valve can be installed only before installing the double-glazed window. In particular, it is necessary to adjust the size of the opening.

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

Market leaders - Aereco and Air-box

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

High quality and practical option

Valves from Aereko are a lining with an attractive appearance(there are color variations), which fits into any interior. The most optimal installation option is during PVC manufacturing windows However, if double-glazed windows are already in place, installation can also be done. This will require some minor 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 require power supply to operate. The operating principle is based on the physical law of thermal expansion.

You can even mount them into the wall. This method is mainly used in wooden buildings, because milling reinforced concrete structures is extremely difficult. From the point of view of its qualities, this manufacturer looks the best analogue On the market. However he has important drawback- high price (from 2500 thousand rubles).

Cheaper analogue

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

Such models are much simpler and require manual control. At the same time, they carry two very important advantages - low cost (on average from 400 rubles) and more simple technique installation Air-boxes are installed in two ways - by milling the frame (as with the previous manufacturer) and by replacing the seal (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 adjusting the size of the opening

The most labor-intensive and costly method involves installing the above-mentioned overhead elements. They are mounted as follows:

The existing glass unit is removed.
The opening is expanded by the amount of the lining.
The glass unit is installed back.
An overlay is installed into the resulting gap.
The cracks are covered cement mortar(or something similar).

The technique looks deadly labor-intensive and unreasonable. Therefore, no one does the 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 the double-glazed window.

The most thoughtful people, when ordering PVC windows, immediately plan to install additional air flow. To do this, the opening is made a little wider than the glass unit requires. This technique is the most effective, and most importantly rational.

Installation instructions for Aereco models

However, what to do if the double-glazed window is already in place? Models from Aereco are installed using a simpler method. It consists of the following:

A location 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. Take this fact into account when choosing a location.

Then marking is done.
We screw the bar to the selected location 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 electric jigsaw We cut holes in the sash and the frame itself.
Setting the bar again.
We secure the valve using special latches.

This procedure is relatively labor-intensive. In addition, it requires special tools, which almost 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 without problems

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

Select the intended installation location.
We cut off the standard seal in this place (which is located on the sash).
Insert a new one (from the kit).
Filming protective film from the valve.
We secure it in the place where the new seal is installed using special latches.
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 is unclear to you, you can watch a video from the manufacturer himself. It will allow you to clearly understand everything.

The 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. To install, you have to dismantle some 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 on the street side. It serves as both an air intake and a canopy 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 high throughput. The length of the ventilation duct varies between 170-400 mm, and the width is 12-16 mm. This is enough to organize a microclimate in large rooms.

Invoices

Integrated into window profile still at the frame manufacturing stage. It will not be possible to install them after the fact. In everyday life, such systems are not used due to the excessively large throughput. They are usually used for ventilation of large offices and trading floors.

The products are indispensable in pavilions with continuous 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 literally half an hour.

Place the product on the top of the sash in the gap. Fresh air enters the room through a small gap in the seal. The design is very simple, but provides 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 proper air exchange. They are best used in the kitchen or small bedroom.

Methods for adjusting valves on PVC windows

Manual

The body of such devices has a handle or a slider. Its movement changes the position of the damper, and therefore 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 damper you have to take a chair. In some models, this problem is solved by installing a cord, like in blinds.
Static. It is very difficult to maintain a constant microclimate with their help. To achieve comfortable conditions, you have to change the position of the shutter depending on the weather. It is not always possible to choose the right mode.

Automatic

Such products have a number of advantages:

Maintain a constant microclimate. The device automatically creates preset comfortable temperature and humidity. The intensity of the air flow is adjusted based on sensor readings.
Autonomous. The product works without electronic components. It does not require mains power or batteries. The flap is moved by nylon tapes. Depending on the pressure, they change their length and, accordingly, the position of the damper.
Economical. The flow of fresh air increases with increasing humidity, for example, if there are many people in the house or laundry is drying. In a calm 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 ventilation pad removes excess moisture from the most favorable place for its formation - the boundary of the temperature difference. If there was evaporation 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 the risk of colds is reduced.
Air exchange between the apartment and the street occurs continuously. You breathe fresh air all day long, and not just during ventilation.

Flaws:

During severe frosts budget models may freeze.
The vast majority of products do not have filter elements. Because of this, dust and foreign odors enter the house.
Full control of the microclimate can only be achieved expensive models. In budget ones you have to independently monitor the temperature and humidity in the house - constantly change 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, which you need to pay attention to when choosing:

Noisy. When air masses pass through a hole of limited cross-section at high speed, noise appears. A comfortable sound level is within 30-40 decibels. Models in which a long narrow gap is formed at the minimum rebate can whistle in strong winds. If the valve does not fit tightly in the operating position, it may rattle.
Performance. Directly depends on the nominal size of the ventilation holes. How larger area channels, the more fresh air enters the house through them. When choosing a specific device, you need to start from the area of the room and the number of residents. Performance different devices varies in the range from 6 to 150 m3/hour. 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 the radiator. In northern regions this may not be enough. Then you need to select equipment with electrical heating.
Filter type. They are absent in structures that are mounted on the sash. Models integrated into the frame can be equipped with filter elements. When using them, dust from the street does not enter the room. But the filter must be constantly cleaned, otherwise the performance of the device drops significantly.
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 structures must be installed at the frame manufacturing stage.
Price. Each of the options listed above affects the cost. If you are too demanding about the microclimate, it is worth comparing window devices with other options for climate control products.

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

There are several types of products on the market for household use. The rating of popular models includes products from French and Russian production:

Air-Box.
Aereco.

We will tell you more about the installation of their systems.

Installation instructions for Air-Box equipment

The device is installed on the top of the sash. We carry out the work in the following sequence:

Mark the center of the frame with a pencil.
We open the sash, apply the inner mounting strip and put marks along the edges.
Using the marks, cut out a section of the rubber seal.
Instead of standard rubber, we insert the seal that comes with the kit.
We install the device itself into the resulting gap in the seal, having first removed the protective film from it.
We fasten the brackets with self-tapping screws.
Close the window and mark the dimensions of the device on the frame.
Using the markings, cut out a fragment of the frame seal.
Insert a new thin rubber band.

Optionally, the product can be supplied with an external air intake. A filter element is installed in it, which traps atmospheric dust. Step by step guide We'll show you how to install it in the video.

Installation instructions for Aereco equipment

The devices are intended for automatic regulation microclimate. They are integrated into the frame, allowing for greater air exchange. During installation, the integrity of the profiles is compromised, so you need to be careful. If you doubt your abilities, it is better to use the services of competent specialists. We carry out the work in the following sequence:

Mark the middle of the window sash.
Screw on a metal template or plastic mounting strip.
Using a drill with a diameter of 4-5 mm, we make centering holes along the edges.
Using the template, mark the outline of the future slots and remove it.
We drill the holes with a drill with a diameter of 10 mm.
Using a jigsaw, renovator or router, we cut grooves between the holes.
At closed window 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 ease of operation, temporarily remove the rubber seal.
Screw the mounting plate from the inside.
We install an element with a valve that regulates air exchange.
WITH outside screw on the protective visor.

You can clearly see the installation process in the video.

If you need to ventilate small room or get rid of fogged windows, suitable simple designs Air-Box type. For autonomous microclimate control the best solution products are becoming Aereco type. And the tips and recommendations given will help you install the ventilation valve yourself.

Material prepared by: Igor Stepankov

Plastic windows appeared here quite recently - the first workshops for their production in the CIS countries appeared in the early 90s of the last century. Nevertheless, it is already difficult for us to imagine our life without plastic double-glazed windows. Their main advantage is that they do not allow street noise and cold air into the apartment. But at the same time we are deprived of the most important thing - natural air exchange. This drawback can be corrected with the help of supply valves on the windows.

PVC windows are good for everyone: they make you feel warm, quiet and comfortable. However, with plastic windows it leaves much to be desired. Without proper ventilation, residents risk earning " side effects"like incessant fatigue and . Of course, you can ventilate the room to ensure an influx of fresh air, but this solution can hardly be considered successful: in windy or cold weather, keeping the windows open is quite problematic. In addition, air enters the room uncontrollably.

Accordingly, for a comfortable stay in the house, you need some kind of device with the help of which air will continuously flow into the room at required quantity. For this purpose they were created. One of their types, window valves, is built into the glass unit, so that a narrow gap is formed that regulates the air supply.

On modern market We offer a wide range of ventilation valves. Usually there are several types of devices.

Manual

Aero valve with manual control It is cheaper than an automatic one, but it is difficult to regulate the air flow manually: after all, the required amount of fresh air greatly depends on the number of people and the state of the microclimate in the room.

Automatic

Automatic valve on the window is more convenient. It has a built-in sensor that determines the level of relative humidity in the room. Thanks to the sensor, the device itself regulates the amount of incoming air and determines when to open or close the ventilation hole.

Rebated supply and ventilation valves

Most a budget option. Fresh air is supplied from the street into the house through special openings in the frame or sash. To install the valve, you do not need to dismantle the windows. Street noise practically does not penetrate into the house. The main disadvantage of this type is the low throughput: the room will still need periodic ventilation.

Slot valves for windows

With slot ventilation, air is supplied through a hole whose width is 12–16 mm and length – from 170 to 400 mm. Some models consist of one universal block, and some - of two blocks: one is installed on inner side windows, and the second - on outer side. Slot valves have a high flow capacity and do not require the removal of windows to install them, which is why they are quite popular in the market.

Handle with supply valve

Mounted instead of the usual handle of a plastic window. When installed, the appearance of the window does not change in any way. The handle valve also often has a built-in filter element that blocks dust.

Overhead valves

This type among others the most effective. However, you cannot do without dismantling the window: the dimensions of the window sashes and frames must be “adjusted” to the device. There is practically no protection from street noise. Therefore, this type is more often used in warehouses and factories than in ordinary apartments.

Based on the material they are made of, models are divided into wooden, metal and plastic.

Apart from installing an overhead valve, there are two ways to install it: with milling (you will have to make a hole in the window block; most likely, you will need the help of specialists) and without milling. The second method is the simplest; with its help you can install the valve on PVC windows with your own hands in a matter of minutes.

You will need:

stationery knife;
Phillips screwdriver;
ruler.

Cut on the frame stationery knife part of a typical seal equal to the length of the valve.
Glue a new one in place of the old seal - it comes complete with the supply valve.
In the same way, remove the excess seal on the sash.
Install the plugs from the kit into the groove on the sash where the previous seal was located.
Attach the valve to the top of the sash (the brackets should be directed towards the window). Secure it with the screws included in the kit.
Install a new seal between the brackets.

Reviews of ventilation valves range from enthusiastic to aggressively disappointed. Almost all users note the same pros and cons.

Advantages:

Unlike micro-ventilation or ventilation with open windows, there are no drafts in the apartment when the supply valve is operating.
Fresh air is supplied continuously, which has a positive effect on the microclimate of your home. The humidity in the apartment is normalized, and the risk of fungus on the walls is reduced.
The device is easy to install and use.
The likelihood of formation on windows is reduced.

Flaws:

In winter, some valve models freeze over.
If you have a manual valve, you will have to frequently adjust it depending on weather conditions, the number of people in the room (i.e. the level carbon dioxide in the air) and other climatic indicators. Since the valve is located at the top of the window, you may need to stand on a chair or stepladder to adjust the operation of the device - this all depends on the height of the windows themselves.
The device, as a rule, is not equipped with filters, so particles of street dust and other pollutants may enter the air.

As we can see, supply valves for plastic windows have both pros and cons. The question naturally arises: is the game worth the candle? What other ones are there that will provide an influx of fresh air and oxygen?

To compare, first you need to define the comparison criteria:

Performance. The performance of the ventilator is measured in cubic meters of air supplied by the device per hour. On average, an adult consumes about 30–40 m3/h. So, if your family has three people, you will need a device with a productivity of 90 cubic meters per hour. It is best to take a ventilator with a performance reserve so as not to overload the device permanent job at maximum settings.
Noise. For comfortable use of the ventilator, a low noise level is important. The imperceptible noise level is in the range of 30–40 decibels, at high performance The normal noise level of the ventilator should be no more than 50–55 decibels. Also, when choosing a device, you need to monitor what sound comes from the ventilator: intermittent noise will most likely irritate your ears.
Filtration system. Air filters are not installed in every ventilator. If you want the air supplied to your apartment to be not only fresh, but also clean, the presence of a filtration system should be a decisive criterion for you.
Air heating system. Air heating is a necessary function for residents of cities where winter is especially harsh. Using the heating system, you can program the device to supply air at a comfortable temperature.
Difficult to install. Ventilator installation is a process that requires care and precision. Some types of ventilators are installed by yourself, while others require the help of specialists.
Price. The price of a ventilator depends on the factors mentioned above - maximum performance, sound insulation, quantity and quality of filters, availability of a climate control system, etc. Thus, the cost can vary from several hundred rubles to tens of thousands.

A climate control valve for plastic windows is the simplest and most cost-effective solution for providing ventilation. Its installation does not require special equipment, through it Fresh air enters the house, it does not make noise - only the level of noise entering the room from the street increases slightly. However, the capabilities of the device are not so great. Its productivity is quite low - up to 35 m3/h. Filters and heating element the device is not equipped.

The wall inlet valve also has a similar device. To install it, you need to make a hole in the wall. As a rule, the performance of a wall valve is higher than that of a window valve (up to 50 m3/h). Some models are equipped with a coarse filter that prevents large dust, lint and insects from entering the room air. Due to installation errors, the wall on which the valve is located may freeze at low air temperatures; There is no air heating system.

A mechanical ventilator is similar to a wall supply valve, but it necessarily contains a fan and more efficient filters. The performance of such a device is limited only by the performance of the fan (40–120 m3/h).
