Aluminium Version

Along with the classic UPVC version in white, the aluminium attachment clad version in all colours is also available.

I-tec Locking

Integrated locking flaps instead of locking pegs ensure the safe locking of the sash. Therefore, the standard hardware version already complies to RC2 N (without lockable handle) acc. to EN1627-1630, standard tested burglary protection.

I-tec Ventilation

Continuous fresh air for the whole room and your well being. Uncontrolled airing leads to energy losses. The I-tec ventilation is equipped with a heat exchanger. 86% heat recovery reduces the energy losses to a minimum.
