Innovative Geneo PHZ system fulfills the highest requirements in the field of heat protection and is certified by Passive House Institute in Darmstadt.

Certified windows for passive buildings

Geneo PHZ system represents unique energy-saving windows technology. Reduction of the heat transfer coefficient to Uf = 0,75 W/m2*K has made Geneo PHZ perfect application for passive buildings. Energy effectiveness is achieved through warm, 6-chamber, 86-mm installation depth profile. The window offers 3mm thick walls (A class window), chambers equipped with warming inserts and special sealing unit containing internal gasket made of durable EPDM rubber .The profile is made of RAU-FIPRO material. This innovative material containing fiberglass offers very good static qualities and is resistant to deformation. RAU-FIPRO profiles do not require steel reinforcements to be used.  Steel sections were reasons for occurrence of thermal bridges. Through elimination of steel reinforcements the heat transfer coefficient values have been significantly lowered.

Stylish and functional windows

Rich palette of colours and wide choice of additional profiles ensures this upvc Rehau window is easily customizable to individual requirements or installation and architectural needs.

Solidity and security

Galvanized steel reinforcements of 1.5-2 mm thickness provide excellent statics of the windows and protection against burglary. High quality hardware and deep mounting of the glazing unit ensure windows are extremely robust and resistant to mechanical damage and various weather conditions.

Durable and easy-to-maintain windows

REHAU profiles are made of the best quality granulated uPVC which is environmentally friendly and can be recycled. Smooth surface of the profile - High Definition Finishing - allows easy maintenance and cleaning. Angled base of the frame rebate is considered as additional advantage of the profile. This allows facilitating water drainage and helps keeping the windows clean.

Windows with arches, triangular windows, trapezoids, circles

The Rehau system allows the making of windows in unusual shapes.  We have experience in the production of windows with arches and triangular, trapezoidal and round windows.
