The advantages of plastic windows have long been appreciated by residents of noisy and dusty cities. Sealed double-glazed windows perfectly protect the living space from atmospheric disturbances, significantly reduce the level of street noise, while not being deformed and serving for a long time. However, they also have a significant disadvantage - the absence of a "breathing" structure, like a tree. A simple technical idea helps out - micro-ventilation of plastic windows, which ensures air exchange in the apartment without creating drafts.
Benefits
Choosing the option to make micro-ventilation, you get the following advantages:
- The window will not fog up.
- Unpleasant odors in the room will disappear.
- The heat or unpleasant smells from the street will hardly bother you.
- No draft will form.
- No high humidity in the room, and therefore no mold or mildew, just a healthy atmosphere.
- You can leave the windows in this position, even if you are outside.
As for the last moment - do not worry that the room will overcool or overheat due to the weather outside, or that intruders will take advantage of this situation, because the gap remains really very narrow.
Ventilation intensity control system for window sashes
So it's safe to say that this option is one of the big benefits and really worth using. In homes where there are elderly, sick people with respiratory problems, or small children, this opportunity should be used without fail. The same goes for apartments where people smoke.
Take advantage of the additional opportunities provided by plastic windows, and your life will become even more comfortable. Micro ventilation will give you comfort and many other benefits.
How to use
In fact, using this option is not difficult at all. For this you need:
- remember that PVC windows open up such an opportunity when the handle is positioned at an angle of 45 degrees;
- choose any of the shutters;
- set its handle to the appropriate position;
- pull on yourself.
Performing such a manipulation, you do not risk anything, because PVC windows are adapted for this. At the same time, other risks are excluded, for example, excessive cooling of the room.
The function can be used even in severe frosts without the risk of overcooling the room.
Micro-ventilation is always fresh air in the apartment
Is additional ventilation really necessary if the living quarters are initially equipped with ventilation systems? The supply and exhaust circuit already guarantees constant air exchange, the norms of which can be found independently in the SNiP documentation. Thanks to the natural impulse, which is the basis of most ventilation systems, the air exchange rate is respected. The multiplicity values are set out in SNiP 2.08.01-89 *.
Air movement pattern inside the apartment
With old wooden windows it was easier: part of the air penetrated through narrow gaps between frames and glass, cracks in window sills and window blocks. Plastic double-glazed windows are hermetically sealed, so the air flow needs to be organized additionally. For this purpose, micro-ventilation systems are installed on PVC windows and a balcony door, providing the air exchange necessary for a full-fledged living in an apartment.
Inlet valve, matched to the texture of the frame
If in the summer open sashes can compete with micro-ventilation devices, then at -15 ° C hardly anyone would agree to open the windows wide open. Thus, special valves and devices provide fresh air flow, protect against condensation, do not create drafts, do not require constant attention or maintenance. But you need to remember that good exhaust ventilation is necessary for the normal operation of the supply devices.

Ready, self-installed supply valve on the window:
The adaptive ventilation system is the best option for maintaining a healthy microclimate in a living room. How to properly install the valve or how to adjust the micro-ventilation mechanism for plastic windows, you can learn from the video instructions. If you do not have enough experience or skill, contact the master - the procedure will take a little time and will be inexpensive.
Installing the device
Ventilated valves are installed in two ways. Let's consider both options in order to have an idea of the technology for installing devices.
For the first option
the extraction of the installed double-glazed unit is characteristic, followed by its replacement with a new one, which has a smaller size. A valve is installed in the gap formed between the glass unit and the frame. The process does not require drilling into the plastic structure, but it has some disadvantages:
- additional costs, as it will be required - not only to order a new double-glazed window, but also to call the master to install it;
- reduction of glass area;
- it is problematic to install the valve yourself.
Second option
the most popular and does not require replacement of double-glazed windows with new ones. Installation is done quickly and independently. We will find out how the installation process looks like below.
For installation - we need the following tool:
stationery knife, ruler and screwdriver.
The valve is supplied with fasteners and two seals 35 cm long.
One of the seals must be installed from the inside of the sash. To do this, open the window, measure 35 cm in the upper part of the sash and, using a clerical knife, cut off the standard seal. Instead, a seal from the kit is mounted. Opposite the cut seal, on the inside of the frame, measure and cut the standard seal in the same way. In this place - we also mount the seal from the kit. Then, three special fasteners should be installed on which the valve itself will be mounted (depending on the delivery). To install the valve, you must first remove the protective film, and then glue the product to the profile. The valve mountings should press firmly against the installed plugs. The valve is fixed to the frame with self-tapping screws. This completes the installation and you can start testing the device.
Pros and cons
You can name the following positive aspects when using a micro-ventilation system:
- Fresh air inflow without hypothermia of the room in winter.
- In the summertime, hot air will not enter the room.
- Protection of windows against fogging, no condensation.
- Lack of drafts.
- Long service life of the mechanism.
- Normal humidity in the room, as a result, the absence of harmful bacteria, mold and fungi.
- There is no stagnant air and unpleasant odors in the room, constant air exchange.
- Windows can be left open in micro ventilation mode, even if the room is left for a long time.
There are practically no disadvantages to this ventilation system, the following can be distinguished as disadvantages:
- The settling of dirt and dust on the mechanism itself, installed on the sash of the window.
- Lack of sound insulation in such mechanisms of low quality.
There are several standard mechanisms for implementing a micro-ventilation system:
Comb (multistage system). It is a small plastic strip with wavy teeth. The flap of the window is fixed by means of a groove in the comb. The distance formed between the sash and the frame can be different, depending on which groove is chosen. The comb is installed after the windows have been installed.
It is one of the most popular micro-ventilation mechanisms as it is easy to install and use and has a number of additional advantages:
- The frame remains intact.
- Using a comb, you can control the air flow by opening the window at a distance of 30 to 60 degrees.
- Low cost. In other words, the comb is a limiter installed on the sash, which makes it possible to open the window to a selected distance.
Climatic valve. This mechanism is installed on top of the sash, just like the comb, does not violate the integrity of the frame and does not affect the sound insulation characteristics. Such a device provides an inflow of fresh air into the room, and the valve membrane takes into account the difference in temperature conditions outside and inside. The climatic valve can be manual and automatic, in the first version the air flow can be regulated by the user himself, and in the second the valves operate independently in the range from 30 to 70% relative humidity.
The option of micro-ventilation with a climatic valve is now quite popular, since air is supplied through the upper part of the sash, without affecting the sound insulation in the room.
Special fittings, the mechanism of which is hidden in the profile. This type of device is called slot micro-ventilation. The gap for air penetration does not exceed 3 mm, this is quite enough for normal circulation of air masses. This is the only mechanism that can be installed only on shtulpovye windows, if the width of the window leaf does not exceed 5 cm. The device is built into the section of the frame near the handle, and when it is rotated 45 degrees, the sash opens slightly.
Multi-stage ventilation system. With this mechanism, a retainer is placed in the swing-out system of the plastic window, with the help of which the sash can be positioned from the frame at a distance of 0.5 to 3.5 cm.
Necessary fittings
The following elements may be required to install the mechanism, depending on the selected type of micro-ventilation:
- Special valve, having movable membranes inside, this allows you to control the level of air penetration into the room.
- Comb, which is a small plastic hook with three rounded grooves.
- Collapsible brake, consisting of two parts, which are attached to the sash and frame, it blocks the opening angle.
- Angle gear, a mechanism that blocks the folding and pivoting position of the sash, it is similar to a comb, but has more grooves.
Blitz Tips
If you need to save money when choosing devices for micro-ventilation, then you should consider the option with a limiter. The main thing is to choose high-quality combs, which have a retainer in each groove. This will prevent a small child or pet from easily opening the window when ventilating.
Micro ventilation systems in the middle price segment are slot ventilation with internal fittings.
The most expensive option is to install an automatic valve. When choosing a climate valve, experts do not recommend saving money. Structures of unknown and unverified brands are often made of low-quality materials that may not withstand winter temperature changes and deform.
Options: comb or climatic valve
Installed climatic valve in the window
The possibilities of micro-ventilation depend on the device of the window. So, the climatic valve option is very common today, and it is a special system on the upper part of the sash, through which air enters - with complete preservation of sound insulation.
Comb competes with this option. This system is a limiter, which is usually mounted on the middle part of the window, and allows you to slightly open it.
The main ways of organizing micro-ventilation
Installation of the restrictor comb
The mechanism of the device is very simple, the operating principle is intuitive. Inexpensive "combs" are available in most hardware stores and firms that manufacture and install PVC windows. Self-installation does not require special skills.
The device, depending on the design, is mounted at the bottom at the angle of the sash or in the area of its handle. This micro-ventilation method is multi-stage - the size of the supply gap between the sash and the frame is regulated by fixing the protruding pin in a certain groove of the comb.
Disadvantages of this ventilation method: fragility of plastic parts; a decrease in the sound insulation properties of a slightly opened window; increased dust content of the seals, which will require additional maintenance.
Slit ventilation
Thanks to special fittings, the flap creates a ventilation gap of a few millimeters at the top. Its value depends on the handle fixed at a certain angle (between horizontal and vertical positions).
With this method of ventilation, as with installing the comb, additional care for the material of the seals and the mandatory seasonal installation of a mosquito net will be required.
Important! Experts know how to make micro-ventilation on plastic windows without prejudice to their other functional characteristics. It is advisable to use the services of professionals when installing and adjusting fittings for slot and valve ventilation
Rotation of the handle for micro-ventilation
Installation of climatic valves
In the upper part of the window, to the width of the supply valve, the seal is removed from the groove of the sash and window frame overlap. The valve is mounted in this place. If micro-ventilation of plastic windows is planned at the stage of ordering, the ventilation valve can be built into the profile during the manufacture of the structure. The ventilation mechanism can have automatic and mechanical (manual) control, which allows you to calibrate the volume of the passed air. The installation of the valve protects the room from insects, noise, dust.
Note! For previously installed window systems, a removable model of the supply valve is purchased. The non-removable version requires factory conditions and is installed during the manufacture of windows
Creating a cozy microclimate, taking care of the health of the family, the micro-ventilation system in plastic windows is increasingly becoming mandatory for installation. The presence of this system even in budget models of window structures is now the norm among progressive manufacturers.

Eliminating the problems of closing the leaves
It takes a minimum of tools and skills to adjust the window and return to normal settings. It is enough to prepare pliers and a hexagon, as a rule, four millimeters. How to adjust the sash and eliminate most of the problems?
Sash skew
The sash skew is removed by simply adjusting the position in the vertical or horizontal plane. For this, there are corresponding screws on the inside of the window on the hinges, which are covered with decorative (protective) caps.
Sash skew can be eliminated by adjusting the bottom and side screws
The protection is removed and with the help of a hexagon they try to correctly set the position of the window sash. The bottom screw adjusts the position up or down, and the side screw adjusts left and right. In this case, you need to close and open the system several times to check how it locks. Adjust the screws, and then the problem will simply disappear.
Loose fit
A loose fit is eliminated depending on the cause of the problem. If the seal is worn out (elasticity is lost, there are tears, etc.), then it must be replaced.
A worn seal can cause a loose fit.
An incorrectly adjusted control eccentric can cause the same problem (summer mode is set in winter). The mechanism regulates the degree of compression of the sash and in the summer position the compression is weaker than in the winter one. The specified mode is indicated by a marker located on the eccentric.
The degree of sash pressing depends on the position of the eccentric
Using a hexagon, plastic windows are set to the winter position (mark "outside"). In the warm season, the marker is returned to summer mode.
Handle wedge
To fix this problem, you will need to remove the sash from the frame. This is done by knocking out the pin from the upper hinge (after removing the protective cap).
To repair the handle, it is necessary to remove the sash
Now you need to insert the "scissors" into the groove where they should be. This process can be done without dismantling the sash, provided that the slopes do not interfere and there is access to the mechanism.
Flap in two modes
A violation occurs when the window is too abrupt and fast to transfer from ventilation mode to closing mode. The solution to this problem is very simple. The sash is pressed against the frame by pressing the upper corner. The lock is clamped to the frame. The handle is placed in open mode. The leaf is locked.
Drainage frame
If the drainage frame has moved away, then it is returned to its place, after having thoroughly cleaned the entire window frame.
The drainage hole is designed to drain water from the window unit
When the sashes sag due to the deformation of the entire window, the intervention of specialists is indispensable. Most likely, a complete window replacement will be required... In this case, the problem arises as a result of wall movements or shrinkage of the house (if it was recently built). The replacement is carried out making sure that such deformations do not recur.
If the window has changed its geometry due to improper installation, then all work on its replacement must be performed by the installer!
What is window micro-ventilation, and why is it necessary
Micro-ventilation - air flow from the street through a window with a fully or almost completely closed sash. That is, the plastic window is closed, but the air can flow poorly.
The task of such ventilation:
- Provide fresh air for human breathing. Even through a small gap, about 10-40 m³ / h can pass (for reference: according to sanitary standards, an inflow of 30 m³ / h for breathing must be ensured for 1 adult).
- Avoid rising humidity.
The humidity in the room with the windows closed will increase due to human breathing, due to drying washed things, due to food being prepared in the kitchen. You can understand that there is such a problem by the sweating windows.
Fresh outside air will reduce humidity levels. This helps prevent mold growth.
Is micro-ventilation necessary?
For PVC windows, micro-ventilation is necessary if, with the window closed, you notice the following problems:
- it is harder to breathe in the room: the air becomes stale;
- mold appears in the room, and it is impossible to bring it out to the end;
- windows sweat: in cold weather, moisture accumulates on the glass, frame, sash, slopes, windowsill;
- clothes and bed linen in the apartment are wet for no reason;
- things after washing (if dried in an apartment) dry for a long time.
Instead of window micro-ventilation, you can put:
Why micro-ventilation is useful: about the benefits
M ikrochelev ventilation is useful both in winter and in warm weather.
In winter (or in autumn-spring), airing the room simply by opening a window or a vent is unlikely to want to: it's cold outside. This can be done, but only occasionally, and not for a long time (for example, during cleaning).
Micro ventilation is good at any time of the year because the windows do not need to be opened. Thereby:
- less street noise is heard;
- poplar fluff, insects do not penetrate;
- precipitation does not fall.
Features of plastic insulating glass units
PVC windows have a number of undeniable advantages:
- have reliable mechanisms;
- safe for health;
- keep warm;
- are distinguished by a long service life;
- different configurations can be selected;
- manufacturing according to individual sizes;
- ease of care;
- excellent sound insulation;
- complete tightness.
Let's look at why the problem of fresh air in the apartment is acute for those who have recently replaced old wooden frames with plastic windows.
The fact is that there were always cracks in the old window blocks, and besides, the tree itself is a breathable material, which provided a round-the-clock flow of air from the street.
Those who have already installed modern window systems often note that it is stuffy in the rooms, and with high humidity, condensation forms on the glass. Thus, the main advantage - tightness - turns into the fact that air circulation is disrupted.
To solve this problem, you can keep windows open at all times and ventilate the room. But this can be inconvenient for a number of reasons:
- in winter you do not want to cool the room too much;
- constant drafts can lead to the development of colds;
- summer heat penetrates the room;
- the sash is not fixed, it can clap from gusts of wind;
- remember to open the frames at least twice a day.
It is much more convenient to install one of the micro-ventilation systems on your plastic windows once. After that, the problem of stuffiness can be forgotten forever.
What is micro-ventilation in plastic windows? It provides constant access of fresh air to the apartment without drafts and excessive cooling of the room and is carried out by installing various micro-ventilation mechanisms.
Microventilation is necessary to provide constant fresh air to the room without drafts.
What is the micro-ventilation mode in a plastic window
The micro-ventilation mode implies the provision of a minimum (micro-slot) natural air flow into the room. To implement this mode, the window is slightly opened, thereby creating a small gap between the sash and the frame, literally a few millimeters.
The ventilation created in this way is quite enough to maintain a normal microclimate in the manned room. Naturally, for such purposes, you should use plastic windows that have the function of adjusting the position of the window.
Comb for window micro-ventilation
The good thing about this ventilation mechanism is that there is no need to put an additional mesh on PVC windows to protect against street litter. It is enough to correctly adjust the size of the gap and street debris, insects or precipitation will not get into the room even with strong gusts of wind.
Is it in all double-glazed windows?
Changing the position of the window in several variations is a function inherent in modern "euro" plastic windows. Modern plastic solutions have the ability to open at different angles (the handle allows you to adjust the position of the window).
Such functions are usually not available for old windows, although it is possible to create slot ventilation there, but not so effective (and street debris will get into the room).But there is no need to rush to install a plastic window - even such solutions do not always have a micro-ventilation mode.
Purpose of the mode
The micro-ventilation mode is used to implement several possibilities at once, that is, it is multifunctional. To begin with, it organizes an air flow acceptable for most cases, capable of maintaining an optimal microclimate in the serviced room.
Moreover, the organization of an adequate air flow is possible in fact without opening a window. And here one more plus is noticeable - a natural flow of air can be done even in the winter season, when it is completely impossible or problematic to open the window (because of the cold).
The use of this mode also allows you to protect the structure from fogging and, as a result, the appearance of condensation. Condensation is fraught with wear and tear of window materials, and is also the main cause of mold and pathogenic fungi.
Sash opening angle for micro ventilation
In addition, a completely closed window without pre-installed inlet valves is not only a high risk of condensation. The serviced room will simply be eternally stuffy, the air will "stagnate", and thanks to micro-ventilation, this can be avoided.
Benefits
There are several main advantages of this method of airing the room, including the main one - cost savings (it will be more expensive to install special valves).
List of other benefits:
- the ability to organize an optimal air flow without loosening the fittings, for which it is enough just to turn the handle;
- in winter, the air flow weakens, but it is also sufficient to prevent fogging and the appearance of condensation on the windowsill with all the consequences (fungus, mold);
- preventing the appearance of mold and mildew not only on the windowsill, but also directly on the window and in the serviced room;
- if the serviced room is small, or it is a balcony / loggia, then in most cases it is not necessary to install an additional supply valve at all.
Modern window features
To ventilate and ensure normal air exchange, it is no longer necessary to open the entire window completely, it is enough to transfer it to one of the available modes of the plastic window.
To ventilate the room, it is enough to turn the handle up, and the sash will deflect to the preset position.
When the window handle is turned 45 degrees, the micro-ventilation mode is set
Micro-ventilation becomes available by turning the control handle at an angle of 45 degrees from the vertical. In this case, a gap of several millimeters is formed, which is quite enough for fresh air to enter the room..
In addition, ventilation can be provided even without unlocking the sash, but for this it is already necessary to make changes to the design itself and install an additional ventilation valve.
These functions, as well as full opening and closing, are available thanks to a mechanism that is adjusted during the installation of the window package.
How to provide micro-ventilation with a comb
Installing the comb allows you to fix the position of the sash in the slightly open state. Most often, there are multi-stage stops that allow the handle to rotate at a slope of 30, 45 and 60 degrees.
The comb is screwed to the frame, and a limiting element is installed on the sash. Thus, the window can be fixed at a gap of 0.3–5 cm. Installation of the comb can be done by any person, if he has a screwdriver. For convenience, you can use a drill, but its requirement is optional.
Detailed algorithm for installing the comb on a plastic window:
- First, release the bolts on the window handle by carefully turning the decorative plastic cap 90 degrees clockwise. Manufacturers provide special recesses for this.
- Unscrew the bolts and remove the handle.
We put on this place the restrictive element from the comb, return the handle from above and tighten the bolts. - Next, the comb itself must be screwed to the frame with two self-tapping screws.
To facilitate the task, the holes can be prepared with a drill.
Tip: in order to put the comb in the right place, before drilling, attach the mechanism to the window and make notes with a pencil.
The main advantages of the comb are the low price and ease of do-it-yourself installation. However, there are incomparably more disadvantages:
- The risk of deforming the profile due to the weakening of the structure with holes for self-tapping screws. If the profiles turn out to be of poor quality, then you can even break the tightness of the flaps.
- Insignificant deterioration of the heat-insulating and sound-insulating properties of the profile, since its integrity is violated.
- Even with the smallest available gap, the gap area is large enough, so the room can cool down quickly enough in severe frosts.
Step-by-step instruction
Installing the comb mechanism
In plastic windows, usually the handle can only be in three positions: horizontal (the window is fully open), vertical up (ventilation mode) and vertical down (the window is closed). If a comb is installed on the window frame, intermediate positions of the handle will appear.
You can buy a comb in any specialized store and install it on the window yourself as follows:
- Turn the cover on the window handle 90 degrees, loosen the screws that secure it to the window and remove it.
- Attach the rod, which has a locking function, to the attachment point, and screw the handle to the same place.
- Attach the comb to the window, taking into account the position of the stem, and mark the places where it will be fixed.
- Screw the comb to the window frame using self-tapping screws.
This is the easiest way to install micro-ventilation on the window.
Key recommendations
The room must be ventilated 4 times a day for 15 minutes. Otherwise, the following ventilation of plastic windows is performed:
- slot micro-ventilation, which provides for the installation of a special mechanism in the profile of the structure, the slot size is 2-3 mm;
- a comb or multi-stage micro-ventilation, which consists in the installation of different slots, this technology is not used in a folding system;
- valve (mounted at the top of the window).
Installing a comb is considered the cheapest method of airing your home. Installation work is carried out on a window profile. The comb is made of plastic. The technology under consideration has 2 drawbacks:
- Deterioration of heat and sound insulation.
- The fragility of the structure.
Rotation of the handle for micro-ventilation.
Slit micro-ventilation of plastic windows provides for the installation of the system into the window profile (during production). Of the minuses of this technology, experts distinguish the formation of a gap (between the sash and the frame), through which dirt and dust will enter the room. A plastic window can be provided with fresh air ventilation. The mechanism used to supply oxygen to the home is easy to use and highly efficient.
A valve is mounted in the upper part of the swing leaf. It ensures a constant circulation of air masses in the house. When installing the considered mechanism, the soundproof and heat-insulating properties of plastic windows do not change. The valve is self-regulating, but it is not adapted to work with significant temperature fluctuations. Therefore, build-ups of ice and snow are formed in the structure, the operation of the mechanism and the thermal insulation of the house are disrupted.
Benefits of ventilation
The ventilation system provided in the plastic window has the following advantages:
- preventing hot air from entering the house on hot days;
- reliable protection against drafts;
- air hygiene support;
- ensuring constant air exchange in the house;
- prevention of hypothermia in the children's room;
- protection against condensation on windowsills;
- long service life of the mechanism;
- the ability to fix the window sash.
Air movement diagram for micro-ventilation.
Such micro-ventilation can be installed with the help of professionals. Upon completion of the installation work, specialists provide instructions. If you turn the handle of the window frame by 45 ° and pull it towards you, then a gap of 1-3 mm will appear (after clicking). The system is installed successfully. Some mechanisms are mounted in the sash profile. In this case, micro-ventilation is triggered when the handle is turned downward by 135 °.
The adjustment of such a system is carried out with the help of professionals. Otherwise you will need a Torx screwdriver. The mechanism is adjusted in two places (upper and lower hinges). Pre-check the diagonals against sagging. From the bottom element, the indicator should be longer (0-3 mm) than from the top loop.
Micro-ventilation: purpose, principle of operation, problems to be solved
Micro-ventilation is a specific form of supply ventilation. For fresh air access, it is not necessary to open the window sashes several times a day for 10-15 minutes, which becomes problematic or impossible in frosty, windy, stormy weather. The inflow of outside air is ensured by creating a minimum gap between the movable sash and the frame of the plastic window or is regulated by a special valve with the sash tightly closed.
The lack of circulation and replacement of air with a simultaneous increase in humidity becomes the cause of general discomfort, lethargy, and a decrease in the protective functions of the body. This microclimate promotes the rapid multiplication of fungi, bacteria and viruses.
Air movement diagram for micro-ventilation
As for any type of ventilation, the purpose of micro-ventilation is to replace the "exhaust" air of the living space with fresh outside air. The air exchange rate can be calibrated and differ by an order of magnitude from full ventilation downward. Hence the term used for this type of ventilation.
It is possible to organize micro-ventilation on plastic windows with a slight change or addition to the design. The consequences will be significant:

- constant air exchange is provided in the room;
- lowering humidity will improve health, prevent the formation of mold and mildew;
- fogging and condensation on glass;
- there are no drafts, the doors do not close spontaneously;
- without overcooling the room in winter, micro-ventilation does not create peak loads on the heating system; in summer, the metered intake of fresh air does not increase the temperature in the premises.
Functions of micro-ventilation of a plastic window
Organization methods
There are 4 ways to organize slot ventilation:
- Installing a comb (accessories, purchased and installed separately).
- Installation of a window valve (fittings, purchased and installed separately).
- Through the mode of slot ventilation on plastic windows (if it is provided, you will not have to buy or install anything).
- Through the holes in the window profile.
Below we will consider each option in more detail.
Comb (+ DIY installation video)
Comb (opening stop, catch) - a strip with grooves that is attached between the frame and the handle on the sash. This device does not allow the sash to open or close, fixing it at a selected distance.
Regulation is stepwise (most often - three-step or four-step). That is, the owner can adjust the degree of opening of the frame.
Basic information:
- How much: 150-300 rubles.
- How much air will it let through: enough for 1-3 people to breathe, even at the very first division (when the flap is minimally open).
- When to choose: the device should be used if there is no slot ventilation mode, and you cannot install the valve yourself and do not want to pay specialists.
More details about (types, manufacturers, prices, installation methods) can be read separately.
Window valve (+ video with the principle of operation)
The window valve is a flat body with an opening and a noise filter that cuts into the frame. Through the valve, air can freely flow from the street into the apartment in a natural way.
If, with micro-ventilation and using a comb, the sash opens (albeit quite a bit), then the valve provides an inflow when the window is completely closed. Some models can be adjusted - they have a regulator to change the section of the hole. That is, the valve can be closed completely, or closed (important in winter, in severe frosts).
Basic information:
- How much: from 1000 rubles.
- How much air will pass through: on average 10-40 m³ / h
- When to choose: if you want to maintain maximum sound insulation (for example, if there is a busy road under the windows).
More details about (manufacturers, prices, installation method) can be read separately.
Window with slot ventilation (+ video)
The best option is if micro-slot ventilation is provided in the window.
If you are going to change windows, you should ask the seller about this mechanism. If the windows are already up, you can check if they have such a function. To do this, turn the knob 45 º. If it turns and locks in this position, there is a micro-ventilation mode.
In this mode, the window does not close completely: a small (3-5 mm) gap remains between the frame and the sash, through which air enters.
Basic information:
- How much it costs: if your windows have such a mode - not at all. If you buy a new window, micro-ventilation fittings will cost 1000-2000 extra rubles to the "normal" cost.
- How much air will it pass: a 3-5 mm wide gap can pass on average about 30-50 m³ / h. The figures are very approximate and depend on the height of the frame and the power of the exhaust ventilation.
- When to choose: if you are going to change windows.
Among the main advantages of this function are:
- Constant air exchange in rooms, even in adverse weather conditions.
Subzero temperatures or strong winds do not allow residents to open windows without discomfort, even for a few minutes. The ventilation function will provide the possibility of air flow without drafts. - Condensation control.
Micro-ventilation is indispensable in double-glazed windows in the kitchen. Intensive use of a multicooker, stove or oven leads to the formation of steam in the air and condensation on surfaces. Without continuous ventilation, water droplets can become a breeding ground for mold growth. - Air hygiene.
The intake of fresh air in the room helps to reduce the concentration of harmful microorganisms and pathogenic bacteria. - Keeping warm in the house during the winter.
According to experts' measurements, window micro-ventilation has an average intensity of no more than 12-15 cubic meters. meters per hour. This practically does not affect the temperature in the house; in a few hours it can drop by only half a degree.
What to consider when buying
If you plan to install a microventilator, you should carefully consider its choice. This makes it easier and faster to deploy overhead options. And the built-in gadgets are the least visible. They are valuable in terms of design.
In addition, other factors are also important, for example:
- if the unit is equipped with automatic regulation, maintaining a comfortable balance of humidity and temperature in the room does not require human intervention;
- climatic valves must have thermal insulation, dust filters, and if there is metal in the structure, a special coating that insulates cold surfaces;
- quality valves are also soundproofed;
- the presence of mosquito nets in the supply valve is encouraged;
- special fittings are installed for shtulp windows.
The technical characteristics of the device should also become a guideline for purchasing. In other words, the throughput provided by ventilation. This indicator depends on the cross-section of the hole in the device body through which air enters and the pressure difference between the street and the room. The normal indicator is an air flow of 20 - 30 m3 / h with a difference of 10 Pa. To make sure that the purchased device is within acceptable limits, it is important to carefully study the documentation or ask a question to the sales consultant.
About noise insulation. The noise level created by ventilation is considered to be comfortable 30 - 35 dB with a fully open inlet. The numbers correspond to the standard sound pressure in the apartment.
Limiter Multivent
This device has two functions at once. Firstly, the limiter always ensures an equal gap between the frame and the sash, no more than 4-5 cm in any position, and secondly, it is impossible to open and close the window without a special key, which makes Multivent an excellent guarantor of safety. Moreover, the limiter will protect the room from both outside penetration and all its inhabitants from accidental opening of the window from the inside, which is especially important in schools, hospitals and kindergartens.
Whichever micro-ventilation system you choose, it will have a number of advantages:
- Regulation of the amount of fresh air in the room and its humidity level,
- Easy to operate,
- No costs for expensive ventilation systems,
- Ease of installation,
- Maintaining a healthy microclimate,
- No condensation on the windows,
- Lack of drafts,
- The invisibility of the design,
- Low price.
The mode of winter ventilation of plastic windows is necessary in the following cases:
- The hood is working in the room,
- There are people in the house who are prone to colds,
- It is necessary to control the humidity level in the room.
Closing problem and its causes
Sometimes a situation may arise when the sash cannot be closed. You should not immediately think about replacing the window, the reasons can be very simple, and their elimination will not require a lot of time and money.
You can start fixing the closing problem after studying the structure of the PVC window
- Skew... This problem occurs due to the loosening of the position control mechanism in the vertical or horizontal plane. In this case, the window sash clings to the edges of the frame and does not fit snugly into place.
- Loose fit... This type of disruption in the functioning of the window may appear for two reasons: wear of the insulation or knocked down settings of eccentrics (pins).
- Handle jammed... In this case, the window does not close, because it is impossible to return the handle to its original (locked) state. The problem arises from jumping out of the groove of an element of the mechanism called "scissors".
- The sash was transferred to two modes at once... In this case, the double-glazed window stands in two positions at once: at opening and at airing. When trying to return the sash to its original position, the control handle is locked and does not turn.
- The drainage bar has come off... This is the least difficult reason. Such a defect occurs due to clogging of the drainage channels or the departure of the frame from the profile.
- Sagging... The sash can cling to the window frame at its edges. If after the adjustment the situation has not changed, there may be only one problem - a change in the geometry of the frame of the entire package due to shrinkage or movement of the walls.
The transition to the sash in double mode may occur when the window is closed during wind or draft.
As you can see, in most cases, sashes on plastic windows do not close for elementary reasons. However, if nothing is done about this, the mechanism will gradually wear out.And the ventilation mode of plastic windows cannot last forever, someday you will still need to close the sash.
What are the ways to eliminate the problems that have arisen and how to adjust the micro-ventilation of the windows?
Ventilation and plastic: compatible or not
Why hasn't a method for efficient ventilation of windows been invented in the modern world? Here you need to be more imbued with the issue of ventilation in houses. Everything here was based on the presence of a hood in the kitchen and bathroom, as well as ventilation through the door and window cracks. This technique was invented a long time ago and has already met the expectations of the inventors.
And now you can look at this invention from the side of arranging new plastic windows. When the structure goes through the installation process, then all cracks and gaps are sealed, thereby creating humidity in the room. This disrupts natural air exchange due to the lack of air flow into the room. Inside a house or apartment it becomes stuffy, humid and discomfort begins. Here a process may begin, which will consist in the following: all the air will not leave the room, but will remain permanently there, and all the smells from neighboring apartments will be felt completely by you.
Here we can highlight other problems that arise during operation. Due to the constant closing of the windows, condensation can form inside the structure, which will interfere with the normal use of the materials. It is best to keep the windows on the micro-ventilation function to prevent the glass from fogging up.
Plastic window ventilation mode
Of course, you can get rid of such problems with simple ventilation in several built-in modes. Also, when purchasing, you should consider the number of cameras. In the presence of a cold temperature regime, it is better to buy multi-chamber windows that will retain heat much better. Of course, you will have to overpay for quality, but the result will not keep you waiting.
How to make micro-ventilation of plastic windows yourself
PVC structures are a universal solution to the problems that arose when installing old wooden profiles: forget about the annoying noise that comes from the street and interferes with rest, the draft that occurs in the cold season and threatens the health of the inhabitants of the house. All these are the advantages of this method, which is chosen to provide a high level of heat and noise insulation. Are there any disadvantages to these designs?
Some owners complain about the lack of fresh air. How to make micro-ventilation of plastic double-glazed windows and stop suffering from heat? After all, this question is relevant in the summer, when people seek to freshen up.

Why the problem arises
The reason for the situation when it is hot outside the window, and there is nothing to breathe in the room, lies in the device of modern translucent structures. The profile design reliably protects the room from winds. Such increased tightness does not always save, and in hot weather it causes serious harm to the health of apartment residents.
Why heat saving - one of the main functions of PVC structures - becomes disastrous for those who decided to install them? The circulation of fresh air in the rooms is disrupted, the humidity in the house rises sharply, mold appears on windowsills and slopes, and we are threatened not only with weakness and a decrease in the body's defenses, but also with poisoning with fungal spores that enter the lungs.
How can you help yourself and ensure complete ventilation of the room? A common option is microventilation. People spend money on special devices, with the help of which the daily flow of air into the apartment is ensured, but this operation is easy to do on your own, without calling the masters.

How to install micro-ventilation of plastic windows
Putting windows on a special mode is not as difficult as most owners of PVC structures think. To do this, you will need some devices that will allow you to easily change the usual position of the sash and normalize the ventilation of the rooms in the house.
To begin with, let's give some advice to those who are tired of the constant stuffiness that occurs with the installation of a double-glazed window:
Everyone knows what micro-ventilation mode is: a similar profile device is shown in the photo and pictures.

Ventilation is provided by installing a mechanism that is not visible from the outside. Most manufacturers of PVC structures sell profiles with the necessary elements already installed in them.
Switching to the desired mode? To do this, turn the knob 45 degrees. The result will be a crack of a few millimeters. This will be enough for constant air exchange.
A common technology used by owners of plastic windows is the installation of a comb. This method is simple, and additional fittings for installation are cheap. Despite the advantages of such ventilation, it has disadvantages. It:
The option considered above is slot micro-ventilation. What are the disadvantages of this technology? It seems that it is practical: the mechanism is built into the profile and normalizes air exchange. Oxygen enters through the gap formed. However, dirt and dust gradually accumulate in the hole, and such a nuisance requires regular maintenance of the surface of the structure.

The last way is to install the valve in the upper part of the profile. The position of such a device is easy to adjust, but this mechanism does not withstand sudden temperature fluctuations. In winter, snow and ice build-ups appear on window sills with this type of ventilation, as a result of which the thermal insulation will be disturbed and the level of humidity allowed in the room will increase.
Fittings for micro-ventilation of plastic windows
What parts are used to set the special mode? A common element that allows you to get a small gap of several millimeters in width is a comb. Most often, these devices are installed on pivot windows and are attached to the frame with self-tapping screws. A special plastic pin securely fixes the ajar sash. cons are obvious:

Another option is a mechanism that was originally built into the profile.
Adjustment of micro-ventilation of plastic windows by yourself
Let's try to understand the features of the installation of step micro-ventilation ourselves. This ventilation method has been approved by specialists. The procedure will not take much time: Needed - replace the angular gear with a similar device with a beak. This device is provided in firms that sell and manufacture fittings for PVC structures.
There are 2 types of corner gears.

prepare the following tools for installation:
First, unscrew the retainer and the parts, then we will do the same with the parts needed for attaching the angular transmission from above and on the sides. Take a flat screwdriver and dismantle the lock and scissors. Next, we will install a new part, place it in the "side beak" position. After the plates are installed in their previous position. Install the screws and proceed to work with the frame. Remove the striker and replace with a comb.

Installation of micro-ventilation of plastic windows: the second option
Another way to provide room ventilation is suitable for those who save money without purchasing additional accessories for the profile. The only thing that will have to be spent is the screws.
Here is a step-by-step instruction for getting rid of stuffiness without resorting to the services of a master:

The ventilation device is ready. Now you can breathe fresh air every day without opening the sash wide open and adjusting the width of the slot.
Do not forget about regular ventilation: no matter how perfect the window arrangement may seem, excessive tightness is harmful, causing the appearance of fungus. Open the sash in micro ventilation mode as soon as you feel stuffy, and carefully monitor the humidity level in the room.

Combination of ventilation and windows
Can ventilation and windows be combined? The answer is simple - you can. There are quite a few options for the device. There are quite a few combinations, some of which are:
- with a window;
- self-ventilated;
- with a comb;
- with ventilation valve;

Windows with a window
A fairly common method of ventilation, which has been used for quite a long time. It provides for the intake of air under the ceiling in the room, which then mixes with the room air, thereby forming a cool and clean product. The appearance of drafts or condensation in the window is excluded here.
The disadvantages of this design are a rather large increase in cost and complexity of the design, which increases the weight of the materials. It is worth noting here that as the design becomes more complex, a large amount of light flux is lost, which makes the room rather dark. This is not always good.
Self-ventilated plastic windows
Self-ventilated windows are the best option for all buildings. They can be used both in civil and industrial construction. This option consists in the fact that the structures use profiles with holes at the top and bottom of the frame. The holes are located in the upper inner and lower outer parts. Air masses, passing through the lower part, are heated, and already heated air enters the room.
The principle works very well, but it has some limitations. Such structures cannot be installed on upper floors due to insufficient supply of air. From such a disadvantage in many systems, a ventilation valve for windows has recently become widespread.
Combed windows
These windows are the most widely used today. With such a device, a regulator is built into the windows, which allows you to either open the window completely or open it in several modes.
This mechanism is very inexpensive, but it works quite well. The comb makes it possible to regulate all incoming masses and leave the window in the intermediate position mode.
