DensGlass® Shaftliner
DensGlass® Shaftliner is a premium 1" Type X gypsum panel (per ASTM C 1658) backed on both faces with coated fiberglass mat. This architecturally specified product is an ideal substitute for heavy masonry construction in fire-rated assemblies for shaftwalls, stairwells and area separation walls.
DensGlass Shafliner is highly mold-resistant* making it ideal for use in moisture-prone vertical and horizontal shaftwall assemblies, stairwell applications and area separation walls in commercial and multi-family construction.
Superior moisture resistance significantly reduces or eliminates callbacks due to moisture-related problems. The inherent moisture resistance of the fiberglass mat shaftwall panels provides leverage in managing construction schedules. Mechanical work such as HVAC system installation can start during the pre-rock phase of construction, helping mitigate risk caused by construction delays.
Georgia-Pacific backs the product with a limited warranty against delamination and deterioration for up to 12 months of exposure to normal weather conditions.
