Page Content The BC Building Code Appeal Board (BCAB) issued a contentious ruling on December 16, 2010 that directly implies that no combustible insulation can be used in non-load bearing exterior wall assemblies of buildings required to be of non-combustible construction unless the wall assembly has been tested to CAN/ULC-S-134, "Fire Test of Exterior Wall Assemblies" (the test that was intended for use on EIFS cladding systems.) Furthermore, by extension, the logic used by BCAB for this ruling implies that other combustible components that are otherwise permitted by subsection 3.1.5 of the 2006 BCBC must also comply with Article 3.1.5.5 and therefore the S134 test. The ruling without more explanation or clarification of intent could have severe impact on common construction practices. Other related publications by Code Officials will also be discussed.
