EPA Door Blower Test Washington

Gig Harbor, Wash. — Builders using structural insulated panels (SIPs) will find it easier to achieve an ENERGY STAR rating with EPA’s release of the SIP Visual Inspection Form.  The Visual Inspection Form replaces the blower door test and energy modeling calculations normally required to meet ENERGY STAR qualifications for homes built with SIP walls and a SIP roof. Conventional wood frame construction does not have this advantage and requires a pressurized blower door test to check the airtightness of the home.
