REHAU Geneo PHZ is an improved, high-tech PVC profile system for windows, designed specifically for buildings with the highest requirements for energy efficiency, in particular for passive houses. It is based on the innovative Geneo system and uses high-tech RAU-FIPRO X material, which provides exceptional strength and stability without the need for steel reinforcement, which is critical for achieving maximum thermal insulation. Thanks to an installation depth of 86 mm and optimized multi-chamber construction, the Geneo PHZ system achieves outstanding thermal insulation indicators corresponding to passive house standards.
Windows made from Geneo PHZ profile provide excellent sound insulation, effectively protecting the room from external noise, and offer a high level of burglary protection. The absence of steel reinforcement makes the profile lighter, which simplifies installation and handling. The smooth surface of the profiles facilitates maintenance. REHAU Geneo PHZ provides wide opportunities for architectural design thanks to the variety of shapes, colors and finishes, allowing the creation of elegant and functional solutions that fully meet the strict requirements of modern energy-efficient construction.

FAQs
This is a version of Geneo for passive houses: 86 mm depth, RAU-FIPRO X composite and special thermal modules for maximum thermal insulation.
In energy-efficient configurations, Uw can drop to ≈0.72 W/m²·K and below, which meets passive house requirements.
Glass units up to 53 mm with warm spacer; sound insulation with proper selection - around up to 50 dB (Rw).
As in Geneo, composite provides rigidity without steel in most cases. This reduces "cold bridges" and structure weight.
Yes, to achieve passive house parameters, warm installation nodes, perimeter sealing and thoughtful room ventilation are important.
Yes, the system was developed for minimal heat loss, so it is effective in cold regions and energy-strict projects.
Yes, configurations up to RC2/RC3, concealed hinges, designer handles and a wide palette of KALEIDO laminations are available.
Geneo PHZ is chosen when maximum thermal efficiency is needed (passive house). If the tasks are simpler, standard Geneo is enough.
