What goes between subfloor and hardwood?

Underlayment is the layer of material that sits between the subfloor and the new hardwood flooring. Subflooring is a layer of plywood or engineered wood that sits at the very bottom layer of the flooring.

Does plywood need expansion gap?

APA recommends a 1/8-inch space between panel edge and end joints. Plywood and oriented strand board (OSB), like all wood products, will expand or shrink slightly with changes in moisture content. If the wood structural panels are tightly butted, there is no room for expansion and buckling can occur.

How thick should plywood be for flooring?

Use building paper! Yep, put down an underlayment of 15-pound felt building paper between a wood subfloor and your hardwood planks, and you can reduce the chance of squeaky floors and control moisture.
