Performance Bulletins

 

Performance Bulletin: "Polyiso and Unfaced Mineral Wool Board Insulation in Commercial Roof Applications."
This Performance Bulletin 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. 

Performance Bulletin: "Measuring the R-value of Polyiso Roof Insulation."
This Performance Bulletin
 

supports and validates the use of PIMA member published LTTR values as the most reliable measure of polyiso thermal value for building owners, designers, specifiers, and contractors. 



Performance Bulletin: "Foil-Faced Polyiso and Mineral Wool Board in Wall Applications."
This Performance Bulletin 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 - also known as mineral fiber board, stone wool and rock wool.

Performance Bulletin: "The Effect of Roof Traffic and Moisture on Thermal Roof Insulation."
This Performance Bulletin shows roofing systems constructed using mineral fiber insulation (also known as mineral wool or rock wool) 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.

Performance Bulletin: "Thermal Resistance and Mean Temperature: A Report for Building Professionals."
This Performance Bulletin shows that polyiso roof insulation R-value shows no significant variation at difference climate zones.

Performance Bulletin: "Polyiso and Flame Retardants"
This Performance Bulletin outlines the fire performance of polyiso insulation.  

Performance Bulletin: "Foil-Faced Polyiso and XPS in Wall Applications"
This Performance Bulletin compares the performance of foil-faced polyiso and XPS insulation in wall applications.
