- 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.
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.
Measuring the R-value of Polyiso Roof Insulation
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.
The 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.
