Passive house


The standard THERM+ system can easily be upgraded to passive house certified standard with minimal additional components. Passive house projects can therefore be fitted with energy saving glazing in a generous, cost effective way, independent of their supporting projects.


  • Certified by the European passive house Institute Dr. Feist in Darmstadt for curtain walls and glass roofs
  • Installations achieve high levels of air tightness (Blower Door Test)
  • Certified with triple glazing, argon gas filling and acrylic spacer
  • Specific accessories (sealing membranes and connection panel profiles) maintain integral passive house quality
  • All pressure and cover profiles from the standard systems can be applied
