What is CDX plywood?
CDX plywood is used under shingles and roofing felt, on walls (just behind the siding and insulation). CDX refers to the grade of the sheet, one side is "C" while other Is "D" meaning it will have imperfections and knots visible with football shaped plugs. "X" refers to the glue used which is stronger and may be exposed to weathering for short periods during repairs.
