Over 20 Years of DensDeck® Roof Boards – Proven Performance

Georgia-Pacific DensDeck products are designed to address four persistent challenges inherent in commercial roofing assemblies: fire resistance, moisture resistance, strength and dimensional stability. DensDeck is a patented fiberglass mat-faced, noncombustible, nonstructural, moisture resistant treated gypsum core panel.

  • Treated gypsum core for moisture resistance and sound insulation
  • Fire, rot and hail resistant
  • Holds up well under normal foot traffic while stiffening and stabilizing roof decks
  • Easy to install in all types of roof systems
  • Ideal product for direct membrane application

With billions of square feet installed in a complete range of roofing systems and climate extremes, DensDeck roof boards have proven their toughness and versatility. The unique construction has been shown to withstand delamination, deterioration, warping and job site damage far more effectively than paper-faced gypsum board and other conventional roofing products such as wood fiberboard and perlite.

DensDeck® Prime combines all the features of standard DensDeck with an enhanced surface treatment. The green surface coating allows uniform spreading of adhesives, which results in a stronger, more consistent bond. For cold mastic and torch applied modified bitumen as well as all fully adhered single-ply systems, DensDeck Prime provides a stronger, more economical installation by reducing the amount of mastic or adhesive, eliminating the field primer and reducing the number of fasteners required to achieve high wind uplift values.

DensDeck® DuraGuard provides a durable low perm, integrated coating with all the features of DensDeck roof board. Additionally, the DuraGuard coating provides an ideal substrate for a wide variety of adhered roofing systems, including self-adhered and hot-mopped membranes. Field primer that is typically used to prepare the substrates for self-adhesive membranes can be eliminated by using DensDeck DuraGuard. Also, DensDeck DuraGuard roof board can be used as a substrate under commercial metal and roof tile applications as a substrate for self-adhesive secondary water barriers.
