Midland, Michigan - Dow Building Solutions has a spray polyurethane foam (SPF) insulation that meets the new, stricter flammability tests for attics and crawl spaces set by the International Code Council Evaluation Services (ICC-ES), Dow said 4 Nov.
Meeting ICC-ES AC377 Appendix X Room Corner fire test means Dow's Styrofoam SPF RS series insulation can be installed without an ignition barrier or intumescent coating in unoccupied attic and crawl spaces, the statement said.
"Spray foam insulation contractors are looking for practical ways to create energy efficient attics and crawl spaces and meet code without adding extra steps," said John Hammer, North America marketing manager for Dow Building Solutions.
Styrofoam SPF closed-cell PU foam serves as both insulation and air barrier, and helps prevent air leakage and heat transfer that can overwork a home's heating and cooling system and thus waste energy, Dow said. (RD)
