DuraGard is made with a high-quality paper that is saturated with phenolic resin solids and overlaid on our exterior-grade plywood panels. The specially selected veneer beneath the overlay provides a smooth surface ideal for painting. DuraGard is manufactured with waterproof resins that meet or exceed all veneer-grade, adhesion, and construction requirements of PS 1-09. DuraGard plywood is stronger, more rigid, and less subject to creep than composition products. Innerplies and backs are all “C” grade or better as outlined in PS 1-09. The overlay is bonded to the specially selected veneer for a smooth, paintable surface. DuraGard may be specified with paper overlay on one or two sides. Roseburg offers DuraGard MDO Premium, which has a thin layer of hardwood veneer directly under the fiber overlay.
