A durable sheathing solution that supports WRBs, insulation systems, and diverse exterior cladding options
Everyone wants a resilient building envelope that can maintain the highest standards of durability, fire resistance, and sound control. A home should do more than simply protect against the elements — it should also be a source of pride.
Glass Mat Gypsum Sheathing offers versatility in design and installation. Thanks to its gypsum core and water-resistant fiberglass facing, gypsum sheathing can be effectively paired with a wide range of exterior claddings, including EIFS, stucco, real brick and stone, and fiber-cement board.
A Reliable Component for Modern Walls
Glass Mat Gypsum Sheathing allows designers to maintain flat, even substrates for a range of cladding systems. Plus, it can be attached to wood and steel stud framing, making it suitable for all kinds of residential wall assemblies including those that incorporate rigid insulation materials.
Fully compatible with standard weather barriers, its surface also acts as a reliable foundation for fluid-applied or sheet-applied weather-resistive coverings, while its glass mat facing helps repel moisture. Together, these qualities allow the material to deliver performance behind most popular cladding choices, including those designed to shed bulk water while remaining vapor permeable for the drying of any moisture that does penetrate the system.
Easily Cut to Any Shape or Size
The easy-to-cut nature of Glass Mat Gypsum Sheathing allows installers to work with precision and efficiency around windows, doors, corners, penetrations, and transitions. Featuring the workability of traditional interior gypsum board, it allows construction crews to execute exacting field modifications without delaying installation or compromising performance.
Flexibility for Curved Surfaces
Using gypsum sheathing allows for flexibility in design. Unlike standard plywood or OSB, some Glass Mat Gypsum Panels are engineered with enough flexibility to bend to curved surfaces such as rounded exterior walls, archways, ceilings, and doorways — enabling more expressive designs when needed.
The fiberglass mat facers provide the necessary tensile strength to maintain the integrity of the gypsum core when the panel is flexed during installation. This contributes to dimensional stability and helps the material maintain its form even in hot or humid conditions.
A Proven Choice for Compatibility
Glass Mat Gypsum Sheathing provides a dependable, high-performance foundation for nearly any cladding system, giving builders a practical solution for a wide range of exterior wall assemblies.
The material’s light weight, durability, and easy-to-install nature makes it a practical, versatile solution for modern residential construction.
