More and more people choose plastic windows for home renovation. This is due to many positive qualities, among which is tightness. And this causes a violation of air exchange in the room. Micro-ventilation of plastic windows solves this problem. The nuances of the device and the installation of this function are described in the article.

Why is there a problem?

When the weather is hot outside, and there is nothing to breathe in the room, this is most often associated with the construction of modern translucent structures. The profile qualitatively protects the room from winds. But this tightness does not always save, and in the heat it can cause severe harm.

For high-quality ventilation, microcirculation is required. Many spend money on special devices with which air enters the apartment, but this is easy to do on your own, without craftsmen.

Concept

Microventilation in plasticwindows is a ventilation function that allows fresh air to enter the room. Often this system is used in winter, when outdoor air is a necessity, and opening the doors is dangerous due to drafts. A small opening of the window will allow you to ventilate the room without harm to people.

When micro-ventilation is required?

For PVC windows, the named function is needed if the following problems are observed with a closed structure:

1. It's hard to breathe in the room: the air is stale.
2. There is mold that cannot be completely removed.
3. Windows sweat: in the cold, moisture accumulates on glass, sash, slopes, window sill.
4. Things and linen are damp for no reason.
5. Products take a long time to dry after washing.

And you can replace micro-ventilation as follows:

1. Tile installation. It provides plenty of fresh air.
2. Wall valve. Delivers less air.
3. Wall heat exchanger. Heats the air without the cost of electricity.

Judging by the reviews, micro-ventilation is quite popular, as it makes the room much more comfortable.

Device

This function works thanks to a special piece of fittings. Thanks to its installation, a small hole appears between the frame and the sash, which has a size of 0.5 cm.

Through this hole in the housingfresh air enters. If there is a strong wind outside, you should not worry that the window will slam shut abruptly and the sashes will be damaged. According to experts, the named mechanism of micro-ventilation of plastic windows is qualitatively fixed.

Advantages and disadvantages

Micro-ventilation of plastic windows has many positive qualities:

1. Fresh air enters the room in winter, preventing hypothermia.
2. In summer, hot air will not enter the home.
3. Windows are anti-fog, no condensation.
4. No drafts.
5. The mechanism works for a long time.
6. Humidity in the room will be normal, which will not allow harmful mold bacteria and fungi to start.
7. The room will be rid of stagnant air and unpleasant odors, which will be facilitated by constant air exchange.
8. Windows can be left open, even if you leave the room for a long time.

The system has almost no shortcomings. One can only notice the presence of dirt and dust on the mechanism, which is fixed on the window sash. In addition, in a room with such a device there is no high-quality sound insulation.

Mechanisms

There are several micro-ventilation mechanisms in plastic windows. One of them is a comb. It is presented in the form of a small plastic bar, which has wavy teeth. The hinged sash of the window is fixed with grooves in the comb. And the distance that appears between the sash and the frame is different. It all depends on the choice of groove. The comb is installed after the installation of windows. According to reviews, thisthe most popular micro-ventilation method.

The advantages of the comb include the following nuances:

1. The frame will be whole.
2. The owners will be able to monitor the air flow by opening the window at 30-60°.
3. Affordable price.

A comb is also called a limiter, which is installed on the sash. With it, micro-ventilation of plastic windows is easily adjusted. According to reviews, such a detail is convenient to use.

A micro-ventilation valve for plastic windows is also used, which is installed on top of the sash. This detail does not violate the integrity of the frame and does not affect the soundproofing properties. With such a device, air is supplied to the room, and the valve membrane takes into account the difference in temperature outside and inside.

The valve is divided into manual and automatic. In the first case, the user can regulate the air flow independently, and in the second case, the valves themselves operate within the range of 30-70% relative air humidity. A detail for micro-ventilation in plastic windows helps air to flow through the top of the sash without affecting the sound insulation in the home. This is its noticeable advantage over the built-in valve.

There are special fittings for micro-ventilation of plastic windows. It is hidden in the profile and provides a small air flow. When installing slotted micro-ventilation in plastic windows, such a gap is not more than 3 mm, but this is enough for high-quality air circulation. Thisthe mechanism is installed only on sash windows, if the width of the canvas is not more than 5 cm. It is fixed to the section of the frame near the handle, and with its turn by 45 ° the sash opens.

A multi-stage ventilation system is also used. In this case, the tilt-and-turn mechanism includes a latch, due to which the sash is located 0.5-3.5 cm from the frame. According to customer reviews, all of these systems are effective for home use.

Mechanism selection

When choosing a ventilation system, it is necessary to highlight some points:

1. Setting method. External products are easier to install than those that need to be fixed in the frame. Plus, they're cheaper.
2. Management. With the help of external mechanisms, micro-ventilation is adjusted in plastic windows. And built-in valves do it automatically.
3. Heat-insulating properties. Mechanisms made of metal elements must be isolated from the side of the room, as frost forms on them.
4. Soundproofing. This factor should be taken into account in order to prevent the penetration of extraneous noise into the room.

Fittings

To install the movement, you need:

1. A special valve that has movable membranes inside. This is necessary to control the level of air penetration into the room.
2. Combs, which is presented as a small plastic hook with 3 rounded notches.
3. Demountable brake, including 2 parts, which are fixed on the sash and frame. It blocks the opening angle.
4. Angular transmission. This mechanism blocks the tilt and turn position of the sash. It is similar to a comb but has more grooves.

Setting and adjusting the comb

If there is no micro-ventilation mode for plastic windows, then it is installed independently, following simple instructions. The duration of the work and its complexity is determined by the selected type of device.

In windows, the handle is usually located in 3 positions. If you install a comb on the frame, there are intermediate positions of the handle. How to make micro-ventilation in plastic windows with its help, we will describe further:

1. Turn the trim on the window handle 90°, unscrew the screws that secure it to the window, and remove it.
2. On the attachment area, you need to attach a rod that will fix the comb, and fix the handle in the same place.
3. The comb is applied to the window, taking into account the position of the rod. It is necessary to outline the areas where it will be fixed.
4. The comb is screwed to the frame with self-tapping screws.

This is the most convenient method of micro-ventilation installation. Even beginners can do this job.

Inlet valve

To perform the installation, you will need a Phillips screwdriver, a marker, a ruler, a clerical knife. The procedure is performed according to the following instructions:

1. The sash opens andpart of the seal is removed with a knife in the area where the valve will be installed.
2. In the place that appears, you need to stick the gasket sold with the valve in the kit, and fix 3 plugs.
3. Then you need to fix the valve with high quality and fix it with self-tapping screws, passing them through the brackets.
4. A seal is placed between the brackets.

The gap that appeared between the valve and the seal allows air to pass through. This valve is controlled by an automatic system or manually. It is important that in winter it is not completely blocked, otherwise frost will form on the window. The product must be cleaned after 6 months, removing dust. For this, household chemicals are used.

To adjust the mechanism, you need a special screwdriver. The upper and lower loops should be corrected, checking in advance that there is no sagging.

Micro-ventilated windows

Windows are now being produced that already have a micro-ventilation function. Moreover, the system is even in budget models. You can buy a window with such a system from the following companies:

• VEKA;
• SALAMANDER;
• REHAU;
• KBE;
• MONTBLANC.

If there is micro-ventilation in the window, then using this function is easy. To do this, the handle is rotated 45°. A special mechanism, which is present in the double-glazed window, fixes the sash in the required position. A gap of no more than 3 mm appears between the frame and the sash. Fresh air will easily enter the room.

There are mechanisms to helpfix the window sash in intermediate positions. The handle then rotates 15, 45 or 60°. Thanks to these methods, it will be easy to regulate the microclimate, and then the room will always be comfortable.

Micro-ventilation is a useful feature. It will be indispensable for houses and apartments where the elderly, children, patients with respiratory problems live. Proper air circulation is the key to the he alth of the whole family.
