The “Red Door of Truth” is the final test of how effective your air control layer really is.
I’m here in Burnaby for the final blower door test on a home where we tried a brand-new approach to our exterior air control layer. Credit to Dennis Froese from Elite Airtight Envelopes for recommending and executing this innovative approach. The result? 0.55 ACH50.
For perspective:
BC Step Code (Step 3) – 2.5 ACH50 or tighter
Net Zero – 1.5 ACH50 or tighter
Passive House – 0.60 ACH50 or tighter
This home – 0.55 ACH50 – Final Blower Door Test.
We’re very satisfied with the result. But ultimately, our clients are the winners. A tighter, more efficient home means better comfort, better performance, and a healthier indoor environment for the family living in it. Well done to the entire team!
