Passive house


The climatic change and the energy transition represent comprehensive challenges, in particular to energetic building and renovation. Our passive house-certified window system fulfils these requirements, thus achieving maximum energy-saving potential.


  • Consistent thermal optimization
  • Maximum energy savings with variable adjustment of the insulation values down to Uf = 0.7 W/(m²K)
  • Innovative system components, such as THERMORIT insulation bars featuring distinctly reduced heat transmission values
