Re: Is Cdx Particle Board Safe For Interior Use?
CDX is plywood, are you sure he's not using OSB? Both can be and are commonly used under hardwood floors, however staples should be used to nail down the hardwood on OSB and nails is on plywood.
CDX means the veneer on one side is rated "C" (defects plugged) , the other side rated "D" (defects not plugged). and exterior glue is used. Almost all plywood is made with exterior glue today. OSB means Oriented Strand Board.
