PIMA disagrees

Abstract
In April, the Polyisocyanurate Insulation Manufacturers Association (PIMA) issued a performance bulletin titled “Measuring the R-value of Polyiso Roof Insulation,” which attempts to refute NRCA’s recommendation that designers use an in-service R-value of 5.0 per inch when specifying polyisocyanurate insulation.
