ASTM C36/C36M
Standard Specification for Gypsum Wallboard
What it measures
Specifies gypsum wallboard: thickness, edge profile, core type and the physical properties each must meet.
Why it matters for a panel envelope
For a Shield™ wall the drywall layer is not just a finish, it is part of the fire rating.
Guardian Shield™
Half-inch or five-eighths-inch drywall provides the rating required by the uniform building codes.
