3/4" - Interior Fire-Treated CDX Plywood

The 3/4-inch interior fire-treated CDX panel adds stiffness for rated interior assemblies that specifically call for a thicker structural panel. Fire performance belongs to the tested assembly, not the panel alone. Verify the required rating, listing, span, fasteners, and local code before purchase.
