Data Sheets
DensDeck® Roof Board
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.
- Tested in accordance with ASTM E84, its surface burning characteristics are Flame Spread-0 and Smoke Developed-0. 5/8"
