Ventilation for window consists of hollow chambered profiled sections, seal, turbulator in blind frame

摘要

The window or door consists of hollow-chambered (HK) profiled sections with a seal (D) between the blind frame (B) and casement. (F). Fresh air is supplied through the blind frame via at least one ventilator seal (VD) to the interior of the building. At least one turbulator (T) is incorporated in the window's blind frame into the fresh-air current (L) from the outside inwards. The turbulator restricts the air-inflow when a set air pressure is exceeded.
