Spruce (CSP) &Fir (DFP) Plywood

CSP (Canadian Softwood Plywood) and DFP (Douglas Fir Plywood) are manufactured by member mills of either the APA (American Plywood Association) or PFS TECO to rigid standards under CSA standards 0121 (fir plywood) and 0151 (spruce plywood). This is your assurance that the panels purchased meet or exceed performance requirements.

Spruce and fir plywood panels are available for a wide range of end-uses: un-sanded sheathing for general structural applications, sanded panels where a smooth finish is desired; plywood panels are also available pressure-treated or fire retardant-treated for specific applications. All panels are composed with waterproof adhesives for exterior use. From structural sheathing applications to jobsite hoarding, there is a panel which will appropriately suit the end purpose.
