Exterior glass-mat sheathing can be used as an underlayment for exterior siding materials such as wood, metal, or vinyl. It is available with a regular or Type X fire-rated gypsum core. The gypsum core is treated for mold/mildew-resistance and is surrounded by a specially designed and coated fiberglass mat. As a result, glass-mat sheathing panels provide more weather protection, mold-resistance, and fire-resistance.
Whether it’s commercial or residential, you’ll find what you need to complete your project’s exterior with our selection of glass-mat sheathing.
