Fresh air valve means fresh air in your home

Ventilation is an important component of comfortable life of a modern man. Emergence of airtight windows caused many problems due to violation of the natural air exchange indoors. It is hard to breathe in a stuffy room, condensate is constantly forming on the windows, and the stale air is a perfect breeding ground for viruses and bacteria. Such microclimate can cause headaches, fatigue, drowsiness. Room airing the room by opening the window sashes brings all of their advantages to nought: noise insulation, energy saving, protection from ultraviolet rays, while preventing a comfortable indoor microclimate. In addition, there are draughts that can adversely affect the health of all family members.

A variety of different devices have been invented to provide good ventilation, but perhaps the most efficient, is the fresh air valve normalizing microclimate in the room. It provides a natural inflow of fresh air with an airtight window. That’s why the fresh air valves are widely used in the design of modern buildings and structures.

Continuous dust penetration into the apartment

Noise from the street
