Plywood & OSB at A&P Supply
OSB sheathing and cement backer board in stock, with plywood in the common thicknesses and finishes.
OSB is our workhorse panel — wall and roof sheathing and subfloor, stocked in the standard sheet size. Cement backer board is confirmed stock for tile floors, tub surrounds, and any wet-area substrate.
Plywood covers cabinet and finish work, including raw, UV1, and UV2 finishes. UV1 is finished on one face, UV2 on both — the difference matters when a panel's back side will be visible.
Common plywood sizes are shown on this page, but panel availability moves. Call to confirm what is on the floor before you plan around a specific thickness.
