All of our plywood has exterior glue and can be used outside. CDX is standard plywood for roofing and sheathing. AC is nice looking sanded plywood. OSB (Oriented Strand Board) is an engineered sheathing product that many people refer to as wafer board, and can be used in place of plywood in many situations. T-111 is plywood with a rough sawn face used for siding. Particle board, peg board, and masonite are for inside use only. All sheets are 4ft x 8ft unless otherwise stated.
We also carry and can order a wide variety of James Hardie Brand fiber-cement siding products as well as beveled and shake cedar siding.
