Passive-house curtain walls

THERM+ aluminium, steel and timber

The THERM+ Basic System can be updated to a certified passive-house curtain wall by minimal adjustments. Passive houses can thus be equipped with an energy-saving fixed glazing in a generous, cost-effective way – independent from their supporting structure.


Passive-house certification based on the newest criteria

The complete curtain wall system THERM+ is certified according to the newest criteria by Passive-House Institute Dr. Wolfgang Feist. The comfort criterion in passive-house of UCW = 0.80 W/(m²K) is fulfilled by the mullion-transom curtain wall systems THERM+ A-V and THERM+ S-I coming in system widths 50 and 56 mm, as well as by THERM+ H-V with system widths 50, 56 and 76 mm. All certifications consider the influence of srewing using RAICO’s standard pessure plate srews and RAICO’s special glass carriers made of synthetic.
