PIMA’s Expanded QualityMark Certification Program Achieves Milestones in First Year of Implementation
ARLINGTON, Va. — The Polyisocyanurate Insulation Manufacturers Association (PIMA) has expanded its voluntary QualityMarkCM 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.
