Abstract
This technical bulletin was issued to advise its members of new technical information regarding polyisocyanurate roof insulation. Recent changes in the blowing agents and manufacturing process of polyiso foam roof insulation urged WSRCA to commission laboratory testing to examine the thermal resistance (R-value) of the current generation of polyiso. The bulletin explains general background information, the natue of the testing WSRCA has undertaken, the results of the testing, and offers recommendations to designers and roofing contractors that practice in the western region of the United States.
