BLOWER DOOR TEST AT A RENOVATION

Renovation of a big house of 400m² in Sakskobing (Denmark).
The customer opted for ALUTHERMO QUATTRO because of its high thermal performance which also guarantees a perfect air tightness.
This air tightness is proved by the Blower Door test (following the standard EN 13829) which was made after the renovation with a result of 0,26 liter/second/m².
