PIMA & Polyiso Insulation

Polyiso is a closed-cell, rigid foam board insulation used in roof and wall assemblies within commercial and residential buildings of all types. Because of its high thermal performance, it is the product of choice for energy-aware architects, specifiers, builders, building owners, contractors and consumers.

As one of North America’s most widely used, most readily available and most cost-effective insulation products, Polyiso has been cited by the U.S. Environmental Protection Agency for its responsible impact on the environment. (Health & Environment page)

For over 25 years, the Polyisocyanurate Insulation Manufacturers Association (PIMA) has served as the unified voice of the rigid polyiso industry, proactively advocating for safe, cost-effective, sustainable, and energy-efficient construction. PIMA is a widely respected, multidimensional trade association whose members strenuously advocate for energy-code development and adoption, and invest numerous hours developing technical standards to improve overall building performance.

PIMA’s members, who first came together in 1987, include a synergistic partnership of polyiso manufacturers and industry suppliers. To learn more, visit
