Drywall Materials: Types and When to Use Them

Not all drywall is the same. Choosing the right product for the application prevents callbacks and code issues.

USG Sheetrock 5/8" Type X
Used for: Fire-rated assemblies

Required at garage-to-living-space separations and per California residential code in specific applications.

USG Mold Tough (MR board)
Used for: Bathrooms, kitchens

Fiberglass mat face won't support mold growth. Required behind tile backer in wet areas.

Georgia-Pacific Dens-Armor
Used for: High-moisture areas

No paper facing — nothing for mold to feed on. Specify in bathrooms without tile on walls.

USG Sheetrock 1/2" standard
Used for: Standard walls and ceilings

Our go-to for most interior applications — consistent manufacturing, widely available, and takes finish well.

We explain every material choice in our proposals. You know what's going into your home and why before any work starts.
