- About PIMA
PIMA Performance Bulletins provide technical and industry information on key topics related to insulation performance. The resources provide the public with information that can be used to evaluate polyiso insulation products and compare their performance to other common insulation types. Industry professional should review individual polyiso manufacturer resources for product-specific information.
Effect of Roof Traffic and Moisture on Thermal Roof Insulation
Demonstrates how roofing systems constructed using mineral fiber insulation and flexible single-ply roofing membranes may experience significant degradation and eventual failure when subjected to water vapor intrusion, especially when combined with roof traffic.
Foil-Faced Polyiso and Mineral Wool Board in Wall Applications
Demonstrates that foil-faced polyiso wall insulation – one of the most thermally efficient rigid board insulations – exceeds most functional performance criteria when compared to mineral wool board.

Polyiso and Unfaced Mineral Wool Board Insulation in Commercial Roof Applications
Demonstrates that polyiso insulation – one of the most thermally efficient rigid board insulations – exceeds most functional performance criteria when compared to mineral wool board in commercial roofing applications.
Polyiso Insulation’s Low-GWP Blowing Agent Solution
Provides information on the environmental performance of the blowing agents used to manufacture polyiso and how their low-GWP impact compares to other insulation products.
Regulations for the Manufacture of Insulation with Low-GWP Blowing Agents
Describes Canadian and United States regulations that prohibit the manufacture and use of foam building insulation products produced with HFC blowing agents and provides information on the effective dates of the regulations.
