SECUROCK® Glass-Mat Sheathing Panels
SECUROCK glass-mat sheathing is a quality non-combustible, moisture and mold resistant panel 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. They score and snap easily and accept fasteners well.
The panels feature a moisture and mold resistant gypsum core encased in a glass-mat facer on both sides and achieve a 10 rating on the ASTM test for mold resistance.
SECUROCK glass-mat sheathing panels are compliant with ASTM C1177 standards (Standard Specification for Glass-Mat Gypsum Substrate for Use as Sheathing), UL Designs U305 and U423, and are approved for use by leading EIFS companies. They can be exposed to the elements for up to 12 months and are guaranteed for five years against manufacturing defects.
SECUROCK glass-mat sheathing panels are available in both 1/2" and 5/8" FIRECODE Type X.
