USG Securock® Brand Glass-Mat Sheathing Regular is moisture- and mold-resistant panel designed for use in high wet areas and under exterior claddings where conventional gypsum sheathing products have traditionally been used, such as brick veneer, properly detailed Exterior Insulation Finish Systems (EIFS), Direct-applied Exterior Finishing System (DEFS), metal panel finishing, clapboard siding, shingle siding, shake siding and conventional stucco 

Regular glass-mat sheathing panels with mold and moisture protection are known as Securock® Brand Glass-Mat Sheathing. To maximize coverage of air/water barrier systems, the panels have a non-combustible, moisture-resistant gypsum core that is encased in a coated fiberglass facer mat.
