Weather-resistant panels are a stable foundation for many exterior finishes. Fiberglass-Faced Gypsum Sheathing helps exterior walls resist air, water and noise infiltration. Gypsum Sheathing is well established as a cost-efficient exterior substrate in commercial construction.

Is gypsum board fire resistant?

Fire rated gypsum drywall is more fire resistant because it contains glass fiber reinforcement and other additives within its specially formulated gypsum core to help it hold up longer to a fire exposure.

Does Gypsum catch fire?

Does Gypsum catch fire? Gypsum (calcium sulfate dihydrate) does not burn so a continuous wall of gypsum board with the seams filled correctly offers a physical barrier to flame.
