What kind of plywood for attic floor.

11 32 plywood attic dek attic flooring panel attic dek plywood subflooring 3 8 plywood 1 2 plywood 4x8. I assume 3 4 inch but there are many types brands to choose from. Some screwed others not. Install two by four blocking between joists or wherever needed to support edges of the plywood that do not have support from the bottom.

The recommended thickness of the plywood subfloor is governed by the spacing of the joists. The decision regarding the thickness of plywood to use for the subfloor in the attic has a lot to do with how you intend to use the attic and it also depends on the spacing of the ceiling joists. Cut the plywood into manageable strips about 10 inches wide to make the job easier. Select 2 to 4 items to compare.

It might seem impossible to haul it up to the attic. 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. Plywood comes in large sheets. My attic is located above my garage and currently the former owner had random pieces of plywood placed up there.
