Where to Buy Georgia-Pacific (DensDeck)

Roof cover board is a rigid substrate installed over insulation to provide a durable surface for membrane attachment and resistance to impact, fire, and wind uplift. It is used in commercial low-slope roofing assemblies beneath single-ply and modified bitumen membranes.

Regular gypsum board is a panel of noncombustible gypsum core faced with paper, used for interior wall and ceiling surfaces. It is installed on wood or metal framing in commercial construction where fire-rated or moisture-resistant boards are not required.

Fire-resistant gypsum panel with a glass-fiber-reinforced core that provides increased fire resistance compared with standard board, typically 5/8 inch thick. Used in rated wall and ceiling assemblies to achieve required fire-resistance ratings in commercial construction.

Gypsum wallboard treated to resist moisture and mold growth, commonly identified by green or purple facing. Used in bathrooms, kitchens, and other high-humidity interior areas as a substrate for finishes.

Shaftliner panels are moisture- and fire-resistant gypsum boards with a specialized core, typically 1 inch thick, installed vertically between shaft framing. They are used in commercial construction to form fire-rated enclosures for elevator shafts, stairwells, and mechanical chases in area-separation and shaft wall systems.

Gypsum panels faced with glass-fiber mats in place of paper for moisture and mold resistance. Used as sheathing, tile backer, and interior board in areas exposed to humidity or weather during construction.

Rigid panel of cement and reinforcing fibers used as a substrate for tile, thin brick, and exterior finishes. Provides a stable, water-durable backer in wet areas such as showers, kitchens, and exterior cladding assemblies.
