What type of drywall is fire resistant?

Type X drywall
Fireproof drywall is the common term; its industry name is Type X drywall. The thickness of this drywall is 5/8-inch, including all layers. Glass fibers are added to the board to help it retard fire. Also, because it is denser than normal gypsum-and-paper drywall, it takes longer for the fire to degrade it.

How do you make drywall fire resistant?

Double the number of Type X sheets on the wall for a simple system installed over fire-resistant fiberglass insulation; each sheet of 5/8-inch Type X drywall is rated to resist fire for one hour, so two layers will produce a two-hour firewall. Put two sheets together on one side or use one sheet on each side of a wall.

How long can a sheet of drywall survive a fire?

For this reason, fire-rated drywall is sometimes called one-hour fire wallboard.
