I-tec Ventilation


Fresh air and energy saving are the main advantages of the directly integrated ventilation in the window. With I-tec ventilation the rooms are aired automatically, energy effi ciently and according to the requirements.

Fresh air ensures wellbeing, good sleep, high concentration and high performance. Even allergy sufferers can breathe again – the optional fi tting of fi lters prevents fine dusts and flower pollen from entering. Through the regulated I-tec ventilation also mould formation is prevented.

Energy saving

Uncontrolled quick maximum air exchange or permanant airing can lead to high energy losses. The I-tec ventilator is equipped with an integrated heat exchanger with high efficiency. Energy losses are reduced to a minimum through the achieved 86 % heat recovery.


The I-tec ventilator is completely integrated into the new home pure window system KF 500. On the outside and inside of the window only narrow ventilation grids are visible. Contrary to conventional ventilation systems, there is neither interference with the interior or exterior architecture, nor high energy losses resulting from uncontrolled quick maximum air exchange or permanent airing. Fitting the ventilator is carried out in the same process as installing the window.

Windows with integrated I-tec ventilation supply the rooms permanently with fresh, clean air. At the same time damp and used air, unpleasant smells and pollutants are automatically exchanged for fresh air. The control element is fitted directly on the window, thus enabling convenient operation of the ventilator.


The I-tec ventilation system also increases security as the window remains closed for the air exchange and therefore, the burglary protection remains intact. When leaving the house there is no uncertainty if the windows were closed after airing.
