Airflow control is one of the most important features to keep in mind when buying windows.
The Regel-air vents mounted only in the top area of the window will meet our client’s expectations, solving the problem of airflow in an intelligent way. 

Ventilation flaps are made of different counterweights thanks to which individual vents react efficiently to blowing wind and air comes out in a controlled manner. First fresh air is brought to the space between the sash and frame where it warms up.

The warmed air rises upwards and via the vent comes in below the ceiling where it mixes with the warmer air in the room.
If condensation forms, it is taken out of the building by the moisture expelling system.



Vent positioning


It can be said that our vents are:
IDEAL for controlling air exchange
IDEAL  for safely dehumidifying  air
IDEAL  for maintenance and easy cleaning
IDEAL for sound and heat insulation
IDEAL for quick installation

Installation of vents does not require special drilling and cutting. Vents can be fitted to new or existing windows.

We recommend the use of vents for improvement of air quality and for the protection against mould.
