Georgia-Pacific's DensDeck StormX Prime Roof Board is a high-performance gypsum roof coverboard that helps prepare commercial rooftops to withstand the impact and puncture caused by very severe hail.

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.

Roofers can trust this coverboard for attached single-ply and adhered single-ply roofing systems thanks to its closed-cell polyisocyanurate foam core.

Georgia-Pacific Gypsum unveiled the latest development in its ongoing 30-year tradition of market-driven innovation at IRE 2018: DensDeck® Prime Roof Board with EONIC™ Technology.

Designed for direct application to combustible decks. 

 SOPRASMART Laminated Boards combine the SOPRALENE SBS-modified bitumen membrane and cover board into one installation layer.
