Fire-Resistant Drywall: When and Why It's Needed in Your Home

What Is Type X Drywall?

Type X drywall is a type of fire-rated gypsum board that contains glass fibers and other non-combustible materials mixed into the core. When exposed to fire, the fibers help hold the board together and resist the passage of heat and flames. A standard 5/8 inch Type X panel provides a one-hour fire rating when installed correctly on each side of a wood-framed wall assembly. It looks identical to regular drywall once painted, so you can't tell the difference visually after installation.

Where Building Code Requires Fire-Rated Drywall

Under California building code, Type X drywall is required in:

• Walls and ceilings between attached garages and living spaces
• Multi-family dwelling unit separations — between apartments, townhomes, or duplexes
• Utility rooms and furnace rooms
• Exit corridors and stairwells in commercial and multi-family buildings

Why Bakersfield Homeowners Should Care

If you're finishing your garage, remodeling to add an attached garage, or converting a raw space into a rental unit, you need to meet fire code requirements. But even when code doesn't strictly require it, some homeowners choose Type X for added peace of mind — particularly on bedroom walls, near the furnace, or in homes with older electrical systems. The material costs a few dollars more per sheet, but the fire protection is well worth the small premium.
