DensDeck® Prime Roof Board

An exceptional fire barrier, thermal barrier, and re-cover board with a pre-primed surface to make the bond even stronger. The patented DensDeck® design employs glass mat facings front and back that are embedded into a water resistant and moisture resistant treated gypsum core, providing excellent fire resistance, moisture resistance, and wind uplift properties.

The unique construction of DensDeck® Prime Roof Boards provides excellent flute spanning and will help stiffen and stabilize the roof deck. Additionally, DensDeck® Prime has been shown to withstand de-lamination, deterioration, warping, and jobsite damage more effectively than roofing membrane substrates such as paper-faced gypsum board, fiberboard, and perlite insulation.
