Rehau Geneo

GENEO is the best energy-efficient window profile system currently available for installation depth of 86 mm. GENEO is unique because of the RAU-FIPRO High-tech material. It is a composite material reinforced with fibers, which makes the profile extremely stable.

Otherwise necessary steel reinforcement is not required in 90% of cases of application. GENEO thus achieves the best values of thermal insulation because thermal bridges, due to, steel no longer occur. GENEO meets the requirements of the Energy Conservation Regulation (EnEV) even surpasses them significantly. At the same time, this window system offers optimal design and comfort prerequisites, without compromising on thermal insulation.


  • Installation depth: 80mm / middle gasket;
  • number of chambers: 6 chambers;
  • thermal insulation: Uf up to 0,86 W/m²K;
  • energy savings: up to 76%
  • material: composite material reinforced with RAU-FIPRO fibers, the entire length of co-extruded outer surface of high-quality RAU-PVC for the best surface quality;
  • sound insulation: without steel reinforcement up to RwP = 47 dB (with glazing Rw = 50 dB)
  • burglary resistance: up to resistance class 3, up to resistance class 2 without steel reinforcement;
  • air permeability: 4 (EN 12207)
  • protection from heavy rain 9A (EN12208)

Reduce energy losses by replacing old wooden / PVC windows from the 1980s (Uf = 1.9, Ug = 3.0) by installing GENEO windows (Uf = 0.86, Ug = 0.5, window dimensions 123×148 cm)

U-value is the heat transfer coefficient. It serves for the evaluation the thermal insulation of a window and is an indicator of the amount of energy that flows through an area of 1 m² in one hour. The lower the value, the better thermal insulation.
