DensGlass Sheathing: What You Need to Know

DensGlass, also known as fiberglass mat sheathing or exterior gypsum board, is a durable and weather-resistant construction panel widely used in commercial and residential building projects. It is designed for superior mold, fire, and moisture resistance, making it ideal for exterior wall assemblies, soffits, and roof applications. Available in standard thicknesses and panel dimensions, DensGlass offers a versatile solution for various construction needs without compromising durability.

Applications & Best Uses:

• Exterior Wall Sheathing: DensGlass is commonly used as an underlayment for exterior cladding systems, including brick, stone, stucco, and siding. Its fiberglass-reinforced core enhances moisture and mold resistance, ensuring long-term structural integrity in high-humidity or heavy-rainfall environments.
• Roof & Soffit Applications: Designed to withstand prolonged exposure to the elements, DensGlass is a reliable choice for soffits, overhangs, and roofline protection. It resists delamination, sagging, and warping, making it an optimal solution for open-framed installations before the final roofing or finishing materials are applied.

Material Benefits:

• Fiberglass-Reinforced Gypsum Core: Unlike traditional paper-faced gypsum, DensGlass features a fiberglass mat surface, offering exceptional durability and resistance to moisture-related damage. This makes it ideal for high-performance building envelopes where mold and mildew prevention is a priority.
• Fire-Rated & Code-Compliant: With a 5/8 in. fire-rated core, DensGlass provides enhanced fire resistance, meeting stringent building codes for commercial and multi-story construction. It is frequently used in fire-rated exterior wall assemblies to improve safety and structural performance.
