Glass-Mat Sheathing Panels
From USGUnited States Gypsum Company’s Securock™ glass-mat sheathing can help weather-protect your buildings.
Securock glass-mat sheathing panels have a noncombustible, moisture- and mold-resistant gypsum core that achieves an ATSM 10 rating. The panels are encased in a double sided, green-colored fiberglass facer and are easy to score and snap without tools.
Securock glass-mat sheathing is suited for use under exterior claddings where conventional gypsum sheathing products have traditionally been used. The glass-mat sheathing accommodates adhesives well, and can be attached to framing with hot-dipped galvanized roofing nails or corrosion-resistant screws.
The sheathing is compliant with ASTM C1177 requirements, UL fire resistance and surface-burning standards, and is approved for use by leading EIFS companies. Available in 1/2" or 5/8" thicknesses, it carries a 5-year warranty.
