Which valve to choose?
To choose the optimal model of the ventilator for installation on plastic windows, it is necessary to decide on the method of its installation and the type of adjustment. The quality of the device largely depends on the manufacturer, and the efficiency of the device depends on the technical characteristics.

Supply valves for PVC windows are divided into three main groups according to their design features:

folded;
slotted;
overhead.
Seam models
Micro-ventilation of the room in this case is uruguay mobile database out by means of a slit in the frame. The window can be equipped with such a device without dismantling the glass unit.

Advantages of folded valves:

affordable cost;
maintaining the heat and sound insulation qualities of the window;
ease and speed of installation;
possibility of automation.
The downside is the low throughput (up to 5 cubic meters/hour). To increase the air flow, experts recommend installing two valves per window.

Seam "supply units" are often equipped with humidity sensors. Preference should be given to models where the sensor-drive is removed from the ventilation duct - this guarantees accurate operation of the valve
