CDX Grade comes from US voluntary plywood Standard PS1-95 for Construction and Industrial Plywood established by APA – The Engineered Wood Association.
“CDX” is not the name of a plywood grade . CDX stands for “C-D Exposure 1 plywood” . C-D means that one side of the plywood is rated “C” grade and the other side is rated “D” grade . The letter “X” means the glue of the plywood is exterior glue . But CDX plywood is not exterior plywood . Because usually the core veneers for CDX plywood are not as good as exterior plywood. CDX plywood is moisture resistant but can not be exposed to water or weather for long time .
CDX plywood is a kind of economical plywood . Usually CDX plywood are sanded but not polished . So the face/back of CDX plywood is rough . Some knots and knot holes exist in the face/back .
