The PIMA Quality Mark cm Program establishes a third-party certification procedure for Long Term Thermal Resistance (LTTR) R-values of permeable faced polyiso roof insulation.
FM Global, one of the world's largest independent commercial and industrial property insurance and risk management organizations, is the administrator of the program. FM Global, or an approved independent third-party selector, takes random polyiso roof insulation samples from each plant of a participating manufacturer, in accordance with the program's guidelines. An accredited testing laboratory then applies the ASTM International-approved techniques to establish and certify the 15-year LTTR-value. To assure continued compliance with the stated LTTR-values, each polyiso insulation plant must have a third-party quality assurance program in place and is subject to unannounced LTTR-value verification. Only those manufacturers that choose to participate in the program will be permitted to use the PIMA Quality Mark logo on their certified products.
