Building professionals expect products to deliver the performance required to meet increasingly stringent standards for the construction of high-performance buildings and homes. No matter the performance metrics (e.g., structural considerations, energy efficiency, system performance, etc.) that drive the decision for material selection, products that use third-party certification programs to measure properties can provide an increased level of confidence to a building professional that they are making the right decision for their next project.<\/p>\n\n\n\n
The Polyisocyanurate Insulation Manufacturers Association (PIMA) operates a voluntary program \u2014 the QualityMark Certification Program \u2014 for Canadian and U.S. manufacturers of polyisocyanurate (polyiso) roof insulation (ASTM C1289, Type II, Class I, Grade 2). The program enables participants to obtain third-party certification of long-term thermal resistance values (LTTR-values) for insulation products independently selected from manufacturing locations. Additionally, the program provides third-party verification of thermal resistance values (R-values) for full thickness products independently selected from distribution locations. PIMA partners with Intertek as the program\u2019s independent administrator. Polyiso is the only insulation product to publish certified LTTR-values under an industrywide, third-party program.<\/p>\n\n\n\n
