Dens deck installation instructions

The patented DensDeck ® design employs glass mat facings front and back that are embedded into a water-resistant gypsum core providing excellent fire resistance, moisture resistance, and wind uplift properties.

The unique construction of DensDeck ® provides excellent flute spanning that stiffens and provides increased foot traffic resistance to the roof deck. Additionally, DensDeck ® has been shown to withstand de-lamination, deterioration, warping, and jobsite damage more effectively than other roofing membrane substrates such as paper-faced gypsum board, fiber board, and perlite insulation.
