88 mm systems Kömmerling 88 proStratoTec: Passive house windows in color certified by PHI Dr. Feist

With the proStratoTec sash profile, the 88 MD and 88 AD systems are supplemented by a versatile variant.

The glass-fiber reinforcement Ultradur®, which is firmly integrated into the profile during the extrusion process, ensures stability in the sash. This means that steel can be dispensed with, which improves the thermal insulation value enormously.

In connection with insertable insulating parts, insulated window sill connection and glass bonding, with the Uf = 0.79 W / (m²K) achieved in this way, passive house windows according to PHI Dr. Feist can be realized in color. Even in sizes that were previously not possible in color.
