ARLINGTON, Va. – The Polyisocyanurate Insulation Manufacturers Association (PIMA) announced that it has issued new technical and performance bulletins as well as updated versions of previously issued bulletins.

New Resources:

• Technical Bulletin 204, “Comparing Fire Performance of Polyiso and Competitive Board Insulation Products,” compares certain fire performance advantages for polyiso, mineral wool board, XPS and EPS insulations.
• Performance Bulletin, “Comparing the GWP of Common Exterior Wall Insulation Materials: An Overview of Global Warming Potential,” assesses the global warming potential (GWP) impact of polyiso wall insulation versus other common insulation products used for exterior walls across the products’ full life cycles.

Updated Resources:

• Technical Bulletin 112, “Moisture Generated During Construction,” highlights how moisture generated during construction can affect the roof system and the construction practices that can be implemented to reduce problems associated with moisture in systems.
• Technical Bulletin 108, “Tapered Insulation Systems,” offers performance details about polyiso tapered roof insulation products and systems, why tapered insulation is used and design considerations for installing tapered insulation systems.

“PIMA strives to be a go-to resource for the roofing, building envelope and general construction industries for technical information on the performance of polyiso insulation products,” said PIMA Technical Director Marcin Pazera. “Maintaining a current library of bulletins is a key part of our strategy to serve the industry and its stakeholders.”
