Ventilation valve for plastic windows. Plastic windows with vent valve

Plastic windows that appeared in our country 20-25 years ago, caused a real sensation, because they looked much more aesthetically than wood, and also provided excellent heat and sound insulation of the premises.

However, after a very short time, it became obvious that their excellent leak-tightness is the cause of the big problems. In particular, after installation of PVC windows during the cold season, unfavorable, too humid microclimate is installed in the rooms, condensation appears on the windows, as well as mold and fungus on the walls and slopes. Of course, one could blame the manufacturer of such insulating glass. But this is not entirely correct, since its task is to make products with reliable locks, which will last a long time, will not lose their attractive appearance and provide tightness. So does this mean that you need to refuse to install insulating glass units? Not at all! It is enough to purchase a quality air vent for plastic windows.

Cause of problems

The question of why wooden windows are "sweating" less, why mold and fungus did not appear during their operation, is of interest to many. According to experts, the fact is that they had gaps through which fresh air constantly flowed into the room. But the double-glazed windows do not let it pass, which means that the moisture released as a result of the life of the inhabitants of the house accumulates in the room and settles on the windows and walls.

Ventilation

Of course, the easiest way, which will mitigate the situation - is the frequent airing of the room. However, experts say that they will be effective only if you perform such procedures every hour and leave the windows open for 5 minutes. Obviously, no one will get up at night 6-7 times to ventilate all the rooms in the house.

Frequent opening of PVC windows is fraught with other dangers:

• Sharp temperature drop;
• Penetration into the house of pollen, which can cause allergy;
• The possibility of intrusion into the house of strangers, which is especially important on the lower floors;
• Contamination of premises with dust;
• Violation of sound insulation.

What to do?

Fortunately, there is a way out, and instead of manually ventilating an apartment or house every half hour, you can simply purchase a vent valve for plastic windows. Such products are mounted directly on the window and let in fresh air that goes to the ceiling and does not form drafts at the level of the window sill, as in airing.

How to mount?

Externally, the ventilation valve for plastic windows is a small pencil case of white, light brown or dark brown color. It is installed directly into the window frame. To do this, a slot with dimensions corresponding to the length and width of the valve is drilled in its upper part, it is mounted as indicated in the instructions, and a visor designed to protect it from the rain is installed externally.

Airbox devices

The ventilation valve for plastic windows, the photo of which is presented below, has even more miniature dimensions. This model Air-Box Comfort, characterized by a mass of positive performance properties. In particular, such ventilators, which provide a change of air in the room with closed window sashes:

• Can be installed on a profile of any design;
• Equipped with a regulator of the volume of supplied air;
• With winds at a speed of 5-6 meters per second (average in the temperate climatic zone), the valves slam shut spontaneously;
• Their installation does not require changes in the window profile; The windows do not suffer at all.

In addition, the ventilation valve for plastic windows Air-Box does not violate the thermal and sound insulation of the room. To ensure that such a system works more efficiently, experts recommend using it in conjunction with conventional electric fans installed in exhaust chambers.

Air-Box Comfort (ventilation valve for plastic windows): installation

Installation of ventilation for double-glazed windows is made in two ways:

• Installation without milling the profile. With this method, good noise protection is provided, and the valve capacity is up to 20 cu. M / h. For its installation, the standard sealant on the frame is replaced with a special gasket included in the vent kit. In this case, a distance of 0.5 cm should remain to the inner bottom corner of the insulating glass unit. Then, on the upper part of the leaf, the place where the ventilation valve for the plastic windows will be installed is selected, and a regular seal of 3.5 cm is cut out. The last step is to remove the protective film from the product, it is installed according to the attached instructions and fixed with screws that are present in the kit.

• Installation with profile milling. The given method provides the raised productivity (a pass in a premise of air from street in volume to 40 cubic meter per hour). To install a ventilator with milling on the upper part of the sash, the window is chosen for its installation and the regular seal is removed. Milled to a depth of 1.5 cm. Remove the protective film from the seal on the product, install the vent according to the instructions and fix it with screws.

Advantages of air inlets with respect to split systems

Conventional air-conditioners have the following principle of operation: they take air from the room, cool it, clean it in filters and return it back to the room. At the same time saturation of air in the room with oxygen "from the street" does not occur. Of course, there are split-systems equipped with a device providing supply ventilation, but they are quite expensive. In particular, in models that cost less than 30,000 rubles, they are generally absent. In addition, the installation of air conditioning, which provides free air access from the street, will require the laying of air ducts, and they themselves consume electricity, while the valves for the windows are autonomous. Thus, these ventilators are also economical.
