1/2 in x 4 ft x 8 ft USG Securock Brand Ultralight Glass-Mat Sheathing

Securock® Brand UltraLight Glass-Mat Sheathing are 1/2 in. (12.7 mm) lightweight glass-mat sheathing panels with moisture and mold resistance—up to 15% lighter than other glass-mat sheathings. The panels feature a noncombustible, moisture-resistant gypsum core that is encased in a coated fiberglass facer mat to maximize coverage of fluid-applied air/water barrier systems. When tested in accordance with ASTM D3273, Standard Test Method for Resistance to Growth of Mold on the Surface of Interior Coatings in an Environmental Chamber, the panels score a "10." These sheathing panels are intended for use under exterior claddings where conventional gypsum sheathing products have traditionally been used, such as brick veneer, properly detailed Exterior Insulation Finish Systems (EIFS), clapboard siding, panel siding and conventional siding.
