ARLINGTON, Va. — The Polyisocyanurate Insulation Manufacturers Association (PIMA) has expanded its voluntary QualityMark^CM certification program for Canadian and U.S. manufacturers of polyisocyanurate (polyiso) roof insulation. The program enables participants to obtain third-party certification of long-term thermal resistance (LTTR) values for insulation products independently selected from manufacturing locations.

The expanded program now includes third-party verification of thermal resistance values (R-values) for full thickness products independently selected from distribution locations. Results from the expanded program criteria will be published starting in 2023.

“PIMA began implementing QualityMark’s new program requirements in Q2 2021,” said PIMA President Justin Koscher. “While the pandemic presented early challenges that included travel restrictions for independent agencies involved in product selection, we are encouraged by the program’s success as we hit the one-year mark of the implementation phase. The past year has enabled PIMA to verify that the expanded program will provide end users with valuable information on performance by selecting and testing products on a more frequent basis.

“We will continue to work with program participants, testing laboratories and our third-party program administrator Intertek throughout the second half of 2022 and look forward to sharing additional program details including program results in 2023."

The QualityMark program was first launched in 2004 to enable polyiso manufacturers to obtain third-party certified LTTR-values for permeable faced polyiso roof insulation products manufactured in Canada and the U.S. 

“Polyiso is the only insulation product to publish LTTR values certified under a third-party program,” said Marcin Pazera, PIMA technical director. “Our QualityMark Program is a valuable and credible tool for end users of polyiso, and will provide the construction industry with the confidence that selecting polyiso insulation means selecting the best insulation for roofing projects.”
