In the past decade, the polyiso industry created and shipped enough board feet of insulation that it would rise to 14.7 miles into the sky if installed to cover a football field.

Designed for direct application to combustible decks. 

National Gypsum has launched DEXcellTM: a new family of high-performance roof boards for commercial roofing systems.
