Home » PIMA Releases Research Report on Roof Insulation R-Value and Temperature
WASHINGTON — The Polyisocyanurate Insulation Manufacturers Association (PIMA) has announced the release of a research report demonstrating that the R-value of polyiso roof insulation shows no significant variation within the average winter and summer temperature ranges across North America.
The PIMA report, titled “Thermal Resistance and Mean Temperature: A Report for Building Owners and Design Professionals,” was developed as a comprehensive response to recent articles that questioned the thermal performance of polyiso roof insulation in colder climates.
