DensGlass Sheathing

DensGlass® Sheathing helps add performance and durability to a wide range of fire-rated and non-fire-rated building assemblies. The #1 architecturally specified fiberglass mat gypsum sheathing1 for more than two decades, DensGlass is built to stay strong and provide superior moisture and mold* resistance.

Widely recognized by the GOLD color, DensGlass Sheathing is the ideal choice for the high-performance built environment:

  • Ideal behind brick, siding, EIFS, stucco and other permanent claddings
  • Provides a rigid substrate for a wide variety of air or water-resistive barrier systems
  • Helps maintain flexibility with construction schedules despite bad weather
  • Backed by a limited warranty against delamination and deterioration for up to 12 months of exposure to normal weather conditions.
Mold-Resistance Testing

*DensGlass® sheathing panels have scored a 10, the highest level of performance for mold resistance under the ASTM D 3273 test method. When tested, as manufactured, in accordance with ASTM D 3273, the score of 10, in the ASTM D 3273 test, indicates no mold growth in a 4-week controlled laboratory test. The mold resistance of any building product when used in actual job site conditions may not produce the same results as were achieved in the controlled, laboratory setting. No material can be considered mold proof. When properly used with good design, handling and construction practices, DensGlass sheathing provides increased mold resistance compared to standard paper-faced wallboard products.
