Glass Mat Gypsum Sheathing is used to enclose a structure and to enhance exterior walls’ resistance to moisture and fire.

No. Glass Mat Gypsum Sheathing was developed more than three decades ago for use in commercial construction, where it has proven its long-term performance.

Yes. It is manufactured throughout the United States and Canada. Always coordinate with your gypsum panel supplier for project fulfillment.

Glass Mat Gypsum Sheathing is ideal for hot and humid climate zones. Unlike traditional sheathings, the product is highly resistant to expansion and contraction when exposed to variable and extreme environments. Gypsum expands and contracts negligibly, per the National Research Council of Canada (NRCC), while OSB will expand 0.15% per 1% change in the moisture content of the material.

The average one- to two-story production home in non-seismic or non-high wind zones that’s built with Glass Mat Gypsum Sheathing generally does not require specialized bracing or designs. These homes can be designed using the prescriptive IRC methods to resist lateral forces. Larger and more complex homes may require supplemental engineered bracing. Contact the Gypsum Association or any member company for technical assistance.

There are some differences, but cutting is simple, and no formal training is required. For linear cutting, scoring and snapping can be handled with a utility knife. For more intricate, non-uniform cutting, Glass Mat Gypsum Sheathing is easily cut with a saw.

There are many reasons to switch, but we think the most compelling is Glass Mat Gypsum Sheathing’s ability to enhance fire- and moisture-resistance. Using Glass Mat Gypsum Sheathing differentiates your brand and sets your homes apart.

Glass Mat Gypsum Sheathing is prescriptive to the International Residential Code (IRC). The Gypsum Association can work with local code officials to provide relevant technical data. You can also reference our Residential Design Guide for Glass Mat Gypsum Sheathing.

No, Glass Mat Gypsum Sheathing can be designed with the same standard methods as typical gypsum panels or wood structural panels and will take the same amount of time to design as a lateral system using these methods.

Yes, Glass Mat Gypsum Sheathing can be used as an exterior wall sheathing instead of a wood structural panel, with lateral force resisting values comparable to standard gypsum wall panels. Consult a structural engineer. The gypsum lateral force resisting values can be found within the Glass Mat Gypsum Sheathing Design Guide and can be applied with the standard IRC prescriptive design method.

It can be used where fire-resistant construction is required, making it ideal for construction in areas governed by the International Wildland-Urban Interface Code (IWUIC) due to the risk of wildland fire. Glass Mat Gypsum Sheathing that is listed through a third-party agency can typically be used in one of the hundreds of partition assemblies in the GA-600 Fire Resistance and Sound Control Design Manual. Contact the Gypsum Association or any member company for information on an assembly and products that may be suitable.

Glass Mat Gypsum Sheathing performs well even when exposed to wet conditions or other harsh weather during the construction phase of a home. The glass fiber facer is inherently resistant to the elements because the material is naturally resistant to mold and moisture. It helps the panel keep its structural integrity when exposed to water before the home’s cladding or siding is installed. Contact a Gypsum Association member company for information on product warranties related to extended exposure to the elements. For information on job site storage, refer to GA-801, Handling and Storage of Gypsum Panel Products.

Between the fire-, mold-, and moisture-resistant properties and the long lifespan of the Glass Mat Gypsum Sheathing, your home will be secure and protected from the elements. Glass Mat Gypsum Sheathing is more fire-resistant than OSB, and should moisture infiltrate the wall assembly, Glass Mat Gypsum Sheathing will not expand, swell, or rot.

Yes. It can be used where fire-resistant construction is required, making it ideal for construction in areas governed by the International Wildland-Urban Interface Code (IWUIC) due to the risk of wildland fire.
