What Plywood To Use For Floor?

What type of plywood is used for flooring?

In my experience as a custom home builder, traditional plywood is the best for flooring followed by CDX and then OSB. A strong subfloor is a very important part of building a strong house.

What thickness plywood should I use for flooring?

The recommended thickness of the plywood subfloor is governed by the spacing of the joists. Some experts suggest that 15/32-inch plywood should be standard if the underlying floor joists are spaced 16 inches apart or less, but slightly thicker 3/4-inch plywood should be used for joists spaced further apart.

What kind of plywood do you use for subfloor?

Standard plywood can be used for subfloors, but a better material is 3/4-inch tongue-and-groove plywood subflooring. The tongue-and-groove edges interlock to resist movement along the panel edges and create an overall stiffer floor.
