USG Securock® Brand Glass-Mat Sheathing is a noncombustible, moisture- and mold-resistant panel that offers an improved coated fiberglass facer mat to maximize coverage of air/water barrier systems. Designed 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, shingle siding, shake siding, and conventional stucco.
