Regular drywall

The standard gray/white board. Fine for bedrooms, living rooms, hallways — anywhere dry. The workhorse; most of your house.

Moisture-resistant ("green board")

Handles humidity better than standard board. Belongs in bathrooms, laundry rooms, and basements. Not waterproof — just more forgiving. Using standard board in a bathroom to save a few dollars is a classic false economy.

Mold-resistant ("purple board")

A step up: paperless or treated facings that resist mold growth. Good for damp-prone areas. Costs more; worth it where moisture is a recurring fact of life.

Fire-rated (Type X)

Thicker, with glass fibers for fire resistance. Required by code between garages and living space, in furnace rooms, and in many commercial assemblies. We hang it where the plans or code call for it.

Soundproof / quiet board

Denser board (sometimes with damping layers) that cuts sound transfer. Bedrooms, home offices, nurseries, media rooms. It helps — paired with insulation and sealing, it helps a lot.

Cement backer board

Not drywall at all, but it belongs here: the substrate behind tile in showers and tub surrounds. Tile over regular drywall in a wet area will fail. Cement board will not.

Thicknesses

Half-inch is the standard for walls. Five-eighth inch for ceilings (resists sagging) and fire-rated assemblies. Quarter-inch for curving or layering over existing walls.

The wrong-board hall of fame

Part of our job on the free visit is specifying the right board for each spot. See basement drywall and bathroom drywall.

Questions homeowners ask us

What is green board drywall?

Moisture-resistant drywall with a green facing. It handles humidity better than standard board — for bathrooms, laundry rooms, and basements. It is not waterproof.

Do I need fire-rated drywall?

Where code requires it: garage-to-house walls, furnace rooms, and many commercial spaces. We hang Type X wherever the plans or code call for it.

Is soundproof drywall worth it?

For bedrooms, offices, and media rooms, yes — especially paired with insulation. It will not make a room silent, but it takes the edge off meaningfully.
