Placing plywood in attic.

Plywood or chipboard is the least expensive option for storage flooring. Plywood serves capably as ceiling material in garages shops and rec rooms when aesthetic design is not an issue. While this is not the optimal setup it is acceptable to have ceiling joists covered with plywood or osb to use for light attic storage of dead loads. Plywood is viable as a ceiling material particularly in the basement.

I assume 3 4 inch but there are many types brands to choose from. Cut the plywood into manageable strips about 10 inches wide to make the job easier. If necessary block around them with plywood or corrugated cardboard to prevent the insulation from piling up on the vent. The wood should be at least 5 8 inch thick to handle a heavy load.

Install two by four blocking between joists or wherever needed to support edges of the plywood that do not have support from the bottom. Maneuvering heavy 4 x 8 sheets of plywood or osb oriented strand board up to an unfinished attic is sometimes like trying to fit a square peg into a round hole. Since the boards are sold in 4 foot by 8 foot sheets you may need to cut them into 2 foot wide strips to get them into the attic space. 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.

It might seem impossible to haul it up to the attic. To give yourself enough space to ensure adequate insulation under the flooring construct a riser of 2 x 4 s in the attic over the existing joists. Place the insulation back and prepare for the top layering of the attic floor.

In attics built purely for storage purposes you may find 2x6 ceiling joists or in some cases even 2x4 joists. Ensuring adequate insulation under the flooring. The finished subfloor should look like a grid. Start off by measuring the panel to be placed as a layer.
