Wowza, time is flying! And construction on the Maple Bay Passive House is coming along nicely. The envelope is made airtight with taped 3/4” plywood, Siga Majrex air barrier membrane for the roof, and windows installed. The blower-door test proved an air tightness of 0.28 arch was achieved (that’s less than 1/2 of the required 0.6 act for a Certified Passive House)!
