Treated Plywood. We stock an F14 structural and ACQ (Alkaline Copper Quaternary) treated ply, similar to CCA but free of arsenic. It offers protection against insect attack, fungi, termites and wood boring insects. The H3 level indicates that this product is suitable for outdoor, above ground use.
Our H3 ACQ treated plywood is all veneer treated not envelope treated. Veneer treated is the superior method as it allows the panel to be cut yet still retain its preservative properties. Envelope treated plywood, when cut, must have the preservative re-applied to the cut edge.
