The windows for the apartment perform several important functions, among which the air exchange function between the premises and the outside world is not the last value. Old wood windows could cope with this function even in a closed position, thanks to natural slots in wood. Plastic windows are much more sealed, which is not their minus, but causes a need to regularly ventilate the room.
If this is not done, there may be a problem of fogging windows, stuffiness, the humidity of the room will increase. As a rule, plastic windows do not have the usual windows, and the ventilation function is ensured by other systems, the most effective of which is the “comb” system. In the cool times of the year, especially in frost, the window cannot be left ajar for a long time. But you can’t ventilate the room.
There is a way out of the situation, namely the establishment of a comb. This function of regular ventilation creates the most favorable and comfortable conditions for room and air exchange, relieves us of health problems associated with insufficient ventilation or cold in the room.
“Grebenka” got its name for similarity with a similar type of comb. Due to the teeth, the comb allows you to adjust the required distance to which the window sash will open. The technology is very simple and effective, and is also most common among plastic windows. When fixing the sash on a certain version, you can provide an optimal influx of fresh air at any time or day.
The establishment of a comb is not costly, so this function does not affect the cost of plastic windows. As a rule, plastic windows are already sold with this function, but you can also purchase and install a comb on already installed plastic windows.
