Standard Specification for Glass Mat Gypsum Substrate for Use as Sheathing
Also Known As:
The ASTM C1177/C1177M-17 standard specifies the requirements for glass mat gypsum substrates that are intended for use as sheathing or exterior substrate for weather barriers. These substrates have a noncombustible water-resistant gypsum core, with glass mat partially or completely embedded in the core.
The standard covers various physical and dimensional properties that the materials must comply with. The physical properties include flexural strength, humidified deflection, nail pull resistance, water resistance, and core, end, and edge hardness. The dimensional properties include thickness, width, length, end squareness, and edges.
The standard also includes references to explanatory notes and footnotes, which should be considered for clarification purposes. However, these notes and footnotes, excluding those in tables and figures, are not considered as requirements of the standard.
