polyisocyanurate; testing; compliance; ASTM C1289

In late 2015, NRCA conducted physical property testing on a limited number of samples of new (uninstalled) faced, rigid board polyisocyanurate insulation used as components of low-slope roof systems. The purpose was to determine the samples’ compliances with the U.S. product standard for polyisocyanurate insulation, ASTM C1289, “Standard Specification for Faced Rigid Cellular Polyisocyanurate Thermal Insulation.” The results also provide a basis for comparison with previous testing conducted by NRCA in 2002 and 2009.
