SlenderWall Meets Demanding 2012 IECC Thermal Requirements

Recently, fabricated SlenderWall panels completed a series of rigorous ASTM C1363-11, Thermal Performance using a Hot Box, tests. The objective of this test program was to investigate how standard SlenderWall panels could meet the 2012 IECC thermal performance requirements for all climatic zones within the United States and parts of Canada A series of tests were performed on SlenderWall panels containing varying depths of different closed cell foam insulations and gap "spacings" (the gap between the precast concrete exterior skin and the steel stud frame). These separate tests provided the foundation for developing a methodology to ensure that the panel's thermal performance (U-value and continuous insulation) will meet varying customer requirements.


SlenderWall exterior cladding panels will meet 2012 IECC Thermal Requirements from Zone 1 through Zone 8.
