Another air test – 0.37ACH

After a full on week filling the narrowest of gaps underneath all the external door thresholds with silicon, more taping and more filling (the edge where the concrete slab meets the threshold), today we had our second air test.

Calculating internal volumes of the house is pretty complex. Thanks to our Passivhaus consultant Rod, who carefully calculated the whole house volume to be 613.47 m3. Our air test result achieved 0.37 ACH.

This now means we can say with more confidence that we are hoping to achieve the certified Passivhaus standards.
