Types of Drywall
Drywall sheets come in 4'x8', and 4'x12', (We do not stock 4X10 or larger sizes). We recommend 4'x8' sheets for do-it-yourselfers; they're a little easier to work with.

For ceilings and walls with 16" on-center framing use standard 1/2" drywall. For 24" on-center framing, use 5/8" drywall.

For curved walls you want to use either 3/8" or 1/4" drywall. It usually requires wetting before forming on a curved wall. 1/4" drywall shouldn't be used as a single layer, but should be used over an existing surface.


Water-resistant drywall or "greenboard" has the same gypsum core as drywall, but it has a water-resistant facing. It is typically used in wet areas such as a bathtub or shower surround. It's not water-proof, however, and will deteriorate from moisture penetration.


Concrete backerboard, often called by the brand names "Durock" and "Wonder Board", is used as backing for ceramic tile. It has a solid concrete core and is faced on both sides with fiberglass. It's ideal for wet areas like shower walls and bathtub surrounds
