Why Gypsum Sheathing for Residential Construction?

For more than 30 years, architects, contractors, and code officials have embraced the use of Glass Mat Gypsum Sheathing for commercial construction.

What is Glass Mat Gypsum Sheathing?

Innovated more than three decades ago to enhance the fire safety and moisture resistance of commercial buildings, today exterior Glass Mat Gypsum Sheathing is manufactured by multiple companies and is widely available throughout North America to meet the needs of the commercial and residential segments.

A) Glass Mat

A highly durable, UV-resistant, and vapor-permeable material. The glass mat is also resistant to the damaging effects of moisture. Some products include integrated weather barriers and accompanying tapes or sealants, eliminating the need for a separate weather barrier.

B) Gypsum Core

Strong, durable, noncombustible, and mold-resistant when tested in accordance with ASTM D3273. The gypsum core is what makes the product preferable when compared to traditional sheathings.
