Standard Specification for Glass Mat Gypsum Panels
ABSTRACT
This specification covers the glass mat gypsum panels. Glass mat interior gypsum panel, designed for use on walls, ceilings, or partitions and that affords a surface suitable to receive decoration. Glass mat coreboard gypsum panel, and glass mat shaftliner gypsum panel, designed for use as a base in multilayer systems or as gypsum studs or cores in semisolid or solid gypsum board partitions, or in shaftwall assemblies. Glass mat water-resistant gypsum panel, designed to be used as a base for the application of ceramic or plastic tile on walls or ceilings. Glass mat gypsum panel shall consist of a noncombustible core, gypsum, surfaced with glass mat partially or completely embedded in the core. Flexural strength, humidified deflection, null pull resistance, water resistance, and surface water absorption and shall conform to the physical property requirements of the materials specified.
