The following is an excerpt from a report (Number 02-02) that was released by the Structural Insulated Panel Association on April 4, 2002: New Oak Ridge Tests Verify SIP Performance Advantage Test Room With Four-Inch SIPs Blows Away 2x6 Fiberglass Construction in Controlled Side-By-Side Lab Test "SIP room 15 times less leaky" - Oak Ridge Report "A SIP test room has significantly outperformed a 2x6 stick-framed and fiberglass insulated wall in controlled testing under identical laboratory conditions at the government's Oak Ridge National Laboratories (ORNL). Results from a carefully monitored and instrumented study1 in Oak Ridge's climate simulation laboratory showed the SIP construction can be far more airtight than stick-frame construction. " We can put a number on it", says SIPA Executive Director Bill Wachtler. "When it comes to stopping air infiltration and exfiltration, a properly sealed SIP building is 15 times better that the competition." NOTE: Glenville Timberwrights uses 6" EPS wall panels and 8" roof panels. Imagine the energy savings!
