Modern designs isolate the room from street noise and retain heat, but paralyze the normal functioning of ventilation. As a result, the microclimate worsens - the air becomes stale, humidity increases, people experience a lack of oxygen, black mold appears.

Old, imperfect structures effectively coped with the task, providing sufficient air flow even in winter. The disadvantage of wooden frames is poor noise and heat insulation

Trying to restore air circulation by opening a venezuela mobile database in ventilation mode cannot be considered a successful solution for the following reasons:

the advantages of “plastic” are reduced to zero – the efficiency of the thermal insulation of the room is reduced;
ventilation only works when the window is open, which is especially problematic to organize in cold weather or in windy weather;
the air flow is uneven and uncontrolled – drafts appear.
Some manufacturers of window systems have taken into account the consequences of complete tightness and have improved metal-plastic structures.

Violation of air exchange negatively affects the health and life of people. Condensation appears on the windows, slopes and walls become covered with mold - the concentration of toxic substances increases


ventilated profiles;
opening limiters;
partially breathable seals;
glazing beads with an adjustable valve.
To ensure air flow through a previously installed window, a supply valve is used.
