Specialization: master of interior and exterior decoration (plaster, putty, tile, drywall, wall paneling, laminate, and so on). In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, repairs in an apartment or house were done on a turnkey basis with all the necessary types of work.

Not in every house, the owners can afford to keep the sash in the hinged mode in winter due to the low temperature outside or poor heating. And this is where micro-ventilation on plastic windows will help.

Such a function in the cold period will prevent the windows from fogging up, and in the rest of the year it will serve for constant air circulation, that is, as natural ventilation. This mode can be provided by the manufacturer, or you will have to do it yourself.

I will tell you about all this below, and you can also get additional knowledge from the video in this article.

micro-ventilation mode

Option 1 - the function is provided by the manufacturer

I hope you know or have already understood what it is:

perhaps a similar function provided by the manufacturer is the most convenient option;
it turns out that such a lock has four positions, which are provided by the instruction: a handle lowered vertically down is closed, horizontally by 90 ° is open, vertically upwards is a folding mode and upwards at an angle of 45 ° is micro-ventilation;
therefore, in order to set the sash in this mode, turn the handle 45 ° relative to the upper vertical and pull it towards you;
by installing the transom in this position, you provide a stable flow of air, which will save you from not only on the windows, but also on the walls;
in this mode, you should not be afraid of severe frosts - the room will not get cold from this;
but I want to note that the price of windows where the shut-off valve mechanism works in this mode will be higher than usual.

Option 2 - climate valve

Also, air circulation to maintain the microclimate is possible with the help of a climate valve. Such a device may be provided by the window manufacturer, or it can be inserted later with your own hands.

Now you can figure out how to make micro-ventilation of plastic windows with your own hands using a climate valve, if this function was not provided by the manufacturer:

a template is installed on the upper part of the sash on a horizontal profile, according to which the necessary holes will be cut;
but before installation, mark the crossbar so that the installation is in the middle - this is more aesthetically pleasing;

transfer the markup to the outside of the sash - there you will also have to install a template;
now you need to cut the chambers on one side and the other with a grinder - this way you create a niche for installing the valve.

Such devices have their own sound insulation, therefore, after their installation, the noise level in the room remains practically the same as before.

The drive sensors, which are made of polyamide fabric, do not require a power supply. They automatically react to the level of humidity due to their own compression ratio, and adjust the position of the dampers that let air from the street into the room.

Such a device is mounted very easily and quickly - for this you need to have a pencil, a tape measure, a grinder with a cutting disc for metal and a screwdriver at home (you can use a curly screwdriver).

The valve is held inside the profile by screws that are screwed in from the outside, as in the top photo, and by silicone sealant, which closes the joints and gaps.

In this case, the climatic valve of AEREKO JSC, whose representative office is located in the Russian Federation, was used.

Option 3 - comb

But, no matter how good the previous options are, the simplest comb can fully compete with them, which allows you to hold the sash in different modes. Moreover, such a mechanism is very easy to install with your own hands.

The comb itself consists of only two parts, this is a comb latch and a counterpart for constipation. In addition, you will need two more self-tapping screws with a length of no more than 14-15 mm, so that they do not rest against a metal profile and a diameter of 3-3.5 mm, a curly screwdriver or a screwdriver.

In order to install the comb, you will have to do a few simple steps, the first of which is to remove the handle from the sash. To do this, we pull the cover on the pressure plane and turn it horizontally, thereby freeing access to the fastener screws. We unscrew them with a screwdriver or a curly screwdriver and remove the handle.

Place the mating part under the handle and screw it into place.

The latch or comb bar is screwed to the vertical jumper of the frame - to do this, close the sash, install the comb as it will stand in the closed position, moving it 1 mm away from the sash, and screw it on.

Conclusion

If you want to have many opening modes, then the third option is most suitable for you, since it is easiest to adjust micro-ventilation on plastic windows with a comb. If you have any suggestions or questions - write notes in the comments, I will be happy to answer and help!

Among the main advantages of this function are:

Constant air exchange in the premises, even under adverse weather conditions. Sub-zero temperatures or strong winds do not allow the windows to be opened without discomfort to the inhabitants, even for a few minutes. The ventilation function will ensure the possibility of air flow without drafts.
Condensation control. Micro-ventilation is indispensable in double-glazed windows in the kitchen. Intensive operation of the 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 fertile environment for mold to grow.
Air hygiene. The intake of fresh air in the room allows you to reduce the concentration of harmful microorganisms and pathogenic bacteria.
Keeping the house warm in winter. According to the measurements of specialists, micro-ventilation of a window 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.

How to ensure ventilation

For organizing ventilation, the most convenient are:

Slit ventilation with window fittings. It will allow you to slightly open double-glazed windows by 2-3 mm, ensuring the minimum possible air exchange.
Comb controlled ventilation. called a special limiter that is built into the window handle area.
Support for room ventilation with valves. Valves for micro-ventilation are mounted in the grooves of the shutters and frames.

The choice of the optimal option can be made after analyzing all the pros and cons, cost and complexity of installation.

We use fittings of plastic windows for micro-ventilation

Under the concept of fittings, experts generalize various mechanisms that regulate the degree of slotted ventilation of the window and are hidden in the profile.

The most common 2 types of such mechanisms:

Detachable brake. The device blocks the sash in both horizontal and vertical opening modes.
Corner transmission. Most often, the mechanism is built into the profile during the manufacture of the window, however, it can be mounted on an already installed window.

The ventilation fittings are controlled by turning the handle at a certain angle until it clicks. It is better to entrust the internal blocking of fittings to specialists, since professional tools are required for its implementation: hexagons, screwdrivers with various nozzles, as well as pliers.

The advantages of such a micro-ventilation system are:

Aesthetics, as the mechanisms are hidden inside the profile;
The choice of several modes with different degrees of air exchange.

Among the minuses, users highlight insecurity from street noise and dust, as well as difficulties in installation and adjustment (the process requires certain skills and knowledge).

How to provide micro-ventilation with a comb

Installing the comb allows you to fix the position of the sash in the ajar state. Most often there are multi-stage limiters that provide rotation of the handle under a slope of 30, 45 and 60 degrees.

The comb is screwed to the frame, and a restrictive element is installed on the sash. Thus, the window can be fixed to a gap of 0.3–5 cm. Any person can install the comb if he has a screwdriver. For convenience, you can use a drill, but its requirement is not necessary.

Detailed algorithm for installing a comb on a plastic window:

First, we release the bolts on the window handle by carefully turning the decorative plastic plug 90 degrees clockwise. Manufacturers provide special recesses for this.
We unscrew the bolts and remove the handle. We put a restrictive element from the comb in this place, return the handle from above and wrap the bolts.
Next, the comb itself must be screwed to the frame with two self-tapping screws. To facilitate the task, 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 its low price and ease of installation with your own hands. 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 the tightness of the sashes can even be broken.
A slight deterioration in the heat-insulating and sound-proofing properties of the profile, as 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.

How to provide micro-ventilation with a valve

Ventilation valves are a modern solution to the problem of indoor air exchange. The design is installed above the sash in the center of the frame. Before installation, the valve must be replaced on the frame with the one supplied in the kit.

The principle of operation of the climate valve is based on the difference in air pressure outside and inside the building. Indoors, the value is lower, so the system provides a continuous flow of fresh air.

There are 2 types of valve to choose from:

Manual. The user independently adjusts the intensity of air flow using a special knob on the valve.
Auto. The climate valve regulates micro-ventilation depending on humidity and temperature conditions both indoors and outdoors.

The main disadvantage of this method of ventilation is the relatively high cost of the system.

The advantages of the valve are incomparably greater:

Continuous ventilation process with the window closed.
Adjustment of intensity of air exchange.
No drafts.
Protection against dust, insects and street noise.
Preservation of heat in the house in cold weather.

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 that have a latch in each groove. This will prevent a small child or pet from easily opening the window when airing out.

Micro-ventilation systems of the middle price segment are slot ventilation with the help of internal fittings.

The most expensive option is to install an automatic valve. When choosing a climate valve, experts do not recommend saving. Structures of unknown and untested brands are often made of low-quality materials that may not withstand the winter temperature drop and deform.

Unlike old wooden frames, modern plastic windows are more functional. It is not necessary to open them completely for fresh air to enter the room, it is enough to open the sash into the room or set the micro-ventilation mode. However, a situation often arises when the plastic window does not close from the ventilation mode. What to do in this case and what is the cause of the problem?

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 plastic window modes.

To ventilate the room, it is enough to turn the handle up, and the sash will deviate to a predetermined 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.

Additionally, ventilation can be provided even without unlocking the sash, but for this you need 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.

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 quite simple, and their elimination does not require a lot of time and money.

You can start fixing the problem with closing after studying the structure of the PVC window

As you can see, in most cases, the sashes on plastic windows do not close for elementary reasons. However, if nothing is done about it, the mechanism will gradually wear out. And the ventilation mode of plastic windows cannot be eternal, sometime you still need to close the sash.

In what ways to eliminate the problems that have arisen and how to adjust the micro-ventilation of windows?

Elimination of problems of closing of shutters

To adjust the window and return to normal settings, you need a minimum of tools and skills. It is enough to prepare pliers and a hexagon, usually four millimeters. How to adjust the sashes and fix most problems?

Sash tilt

The skew of the sash is removed by simply adjusting the position in the vertical or horizontal plane. To do this, on the inside of the window there are corresponding screws on the hinges, which are covered with decorative (protective) caps.

The skew of the sash 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, after which the problem simply disappears.

Loose fit

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 seal

The same problem can be caused by an incorrectly adjusted regulating eccentric (summer mode is set in winter). The mechanism regulates the degree of pressing the sash and in the summer position the pressing is weaker than in the winter. The set mode is indicated by a marker located on the eccentric.

The degree of pressing the sash depends on the position of the eccentric

Using a hexagon, plastic windows are set to the winter position (“outside” mark). In the warm season, the marker is returned to summer mode.

wedge handle

To fix this problem, you will need to remove the sash from the frame. This is done by knocking out the pin from the top loop (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.

Sash in two modes

Violation occurs when the window is switched too abruptly and quickly from the ventilation mode to the closing mode. Fixing this problem is very simple. The sash is pressed against the frame by pressing on the upper corner. The lock is clamped to the frame. The handle is moved to open mode. The sash is locked.

Drainage frame

If the drainage frame has moved away, then it is returned to its place, having previously cleaned the entire window frame well.

The drainage hole is designed to drain water from the window unit

When the sashes sag due to the deformation of the entire window, it is impossible to do without the intervention of specialists. Most likely, a complete replacement of the window 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). Replacement is carried out, making sure that such deformations will not be repeated.

If the window has changed its geometry due to improper installation, then all work on its replacement must be performed by the installer!

Micro ventilation setting

Micro-ventilation is a built-in function of a modern window, when by turning the handle to the desired position, the sash leaves a gap of several millimeters for air to enter from the street. But you can also install additional devices for organizing normal air exchange.

Comb control

The comb is an additional fitting that works as a limiter for the angle of the sash in the ventilation mode. The window can be installed with a slope of 30, 45 or 60 degrees.

Using the comb, you can set the desired level of ventilation

A plastic comb with recesses for the limiter is mounted on the frame. A hook is installed on the frame itself. It works like a limiter. When switching to the ventilation mode, the frame tilts, and the comb is placed with the desired recess on the limiter.

Valves for micro-ventilation

It is also an additional fitting that is mounted on the window profile. There are two types of valves: manual and automatic. Manually, the user himself sets the required mode of air flow. Automatic valves regulate themselves, providing ventilation depending on the temperature and humidity in the room.

Automatic ventilation valves adjust the level of ventilation depending on the climatic conditions

There are also systems that are located in the handle, they are more aesthetic, and in terms of functionality they are not inferior to their counterparts.

Modern windows allow you to set various modes to normalize air exchange. Minor problems can be completely eliminated on your own, simply by adjusting the window to the desired position. In most cases, closing problems occur with a normal settings failure.

From the article you will learn:

If an optimal microclimate is not created in the room, then any windows, including plastic ones, under certain circumstances, can become covered with water droplets from the inside. This phenomenon is called condensation.

In one of the previous articles, we have already considered, but now we note that in order to combat this phenomenon, manufacturers of light-transmitting structures have provided for the presence of a micro-ventilation function in their products. What is it and what is its essence, we will consider in this article.

The material would not be complete if it were not for the types of window ventilation that exist today, there are only three of them:

Comb. Provides multi-stage ventilation of the room.
. Located above the window sash.
Slotted (micro) ventilation. This type of ventilation, in fact, will be discussed in this article.

Why do you need a micro-ventilation mode?

As you know, PVC windows in the closed state, unlike the old wooden structures of the times of the existence of the USSR, hermetically close the window opening, practically preventing free air circulation.

With a large temperature difference in the street and indoors, the problem of unhindered air exchange becomes especially acute - the appearance of fogging becomes visible (remember the process of cooking in the kitchen). It is in order to prevent such a phenomenon that in modern plastic windows there is micro-ventilation system. PVC structures equipped with it allow air flows to freely circulate between the room and the street, thereby improving the microclimate in the apartment.

Microventilation mechanism.

This window function operates on the principle of forced ventilation. It is activated with a handle, by putting it in a certain position. The maximum possible micro-ventilation is set when the handle is turned at an angle of 45 degrees.

The intensity of such slotted ventilation is regulated by simply turning this knob. In this case, the maximum deviation of the sash from the frame is 1 centimeter.

Mode benefits.

Installing plastic windows in the micro-ventilation mode allows you to fill the room with fresh air, regardless of the time of year, only barely noticeably cooling it.

What is good for a person? With the use of slot ventilation, the room is cooled gradually, while there is no draft in it, unless of course there is a squally wind outside the window.

With the penetration of fresh air flows through the window, unpleasant odors, if any, dissipate, and the air in the apartment gradually acquires the necessary level of humidity.

Important! It is the high humidity in the room that is responsible for the appearance of mold, which is so harmful to the human body.

If a strong wind "looked around" on the street, and the double-glazed window was set to micro-ventilation mode, then you can not be afraid for the integrity of the wings - it will withstand any gusts and not be damaged.

And the last. You can buy PVC windows with a micro-ventilation function at any company that sells such products. The presence of such a ventilation system, even in a budget window model, is the norm today.

More and more people are making their choice in favor of installing plastic double-glazed windows. They are beautiful, comfortable, durable, do not let in noise, cold and dirt from the street. However, their owners, along with the advantages, often note that the room has become stuffy. Micro-ventilation of plastic windows will help to solve this problem.

Today plastic windows become more and more popular. They are easy to use, do not let in noise and cold from the street.

Features of plastic double-glazed windows

PVC windows have a number of undeniable advantages:

have reliable mechanisms;
safe for health;
keep warm;
have a long service life;
you can choose different configurations;
production 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 recently replaced old wooden frames with plastic windows.

The fact is that there were always gaps in the old window blocks, besides, the tree itself is a breathable material, which ensured round-the-clock air flow from the street.

Those who have already managed to install 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 disturbed.

To solve this problem, you can constantly keep the windows open 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 flap from gusts of wind;
don't forget 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 microventilation 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.

Micro-ventilation is necessary to provide constant fresh air to the room without drafts.

How to adjust micro-ventilation

There are several ways to adjust micro-ventilation in an apartment. With their help, you do not have to worry about how to ventilate your home.

Can be installed:

comb;
microslit ventilation;
micro-ventilation valve for plastic windows.

Comb

A comb or opening limiter is the most inexpensive way to ensure the flow of fresh air into the apartment and not open the doors wide open.

The limiter is a scallop-like bar and tongue. A bar (metal or plastic) is attached to the frame. A tongue is installed under the sash handle. Open the window, fix the tongue in the comb, and you will receive an influx of oxygen.

You can do the installation of the comb yourself or use the services of specialists. The advantages of this method include budget and ease of installation.

But there are also disadvantages: during installation, the tightness may be broken. In addition, it is possible to reduce the properties of heat and sound insulation of the system.

micro-slit ventilation

The window sash has mechanisms that allow it to be fixed in different positions. Such fittings are installed during production.

It is possible to set the micro-ventilation mode on an already finished window. To do this, you need to contact the organization that will perform all the necessary work.

This mode has a number of undeniable advantages:

the room is freed from unpleasant odors and harmful substances;
fresh air enters the apartment constantly;
glasses do not "cry";
excess moisture evaporates from the room;
unpleasant drafts are excluded;
precipitation, wind, insects and dust do not fly into the room;
a comfortable temperature is maintained, the room does not cool down in winter, and does not overheat in summer;
with microventilation, the integrity of the system is not violated, anti-burglary properties are preserved.

micro-ventilation valve

Another great way to provide micro-ventilation in the room is to put a valve for plastic windows.

By installing a ventilation valve for plastic windows, you can provide micro-ventilation in the room

It is installed at the top of the window sash. The flow of fresh air is directed to the ceiling. Even in cold weather, you will not feel a draft. There are automatic and manual types of valves on the market, which differ in their cost and the ability to adjust. In many valves, the filter can be changed so that the air entering the room is always clean. You can install the valve both independently and with the help of a specialized company.

The main advantage of the valve is that the integrity of the double-glazed window is not violated and tightness is maintained. And the climate in the room is constantly adjusted.

How to open a window for micro-ventilation

If micro-ventilation is already installed in your plastic windows, then it is very easy to use it. To do this, just turn the handle 45 degrees. A special mechanism installed in the double-glazed window will fix the sash in the desired position. A small gap is formed between the frame and the sash, not exceeding 3 mm, and fresh air will freely enter the room.

There are mechanisms that allow you to fix the sash in intermediate positions. Then the handle can be rotated 15, 45 or 60 degrees, and the frame will be set in the desired mode.

After installing plastic windows, the problem of ensuring stuffiness in the rooms becomes relevant. With the help of these methods, you can effortlessly adjust the microclimate. When installing, do not forget to say that you want to set the micro-ventilation mode. This will allow you to maintain health and well-being.
