Richply D.Fir Marine AB is a high-grade sanded panel made entirely from Douglas Fir species. Panels are constructed using a premium A-face with B-or-better backs and inner plies; glued together under heat and pressure with a phenolic resin adhesive that once cured produces an Exterior bond which is thermally stable, chemically resistant, and suitable for exposure to extreme conditions of moisture and temperature.

Richply D.Fir Marine AB uses a premium A-face limited to a total of nine (9) patches or repairs in a 4’x8’ sheet which gives the panel a beautiful near-blemish-free appearance and surface. The solid core construction (which permits core gaps not exceeding 1/8” or 4 in number) also gives the panel structural integrity and makes the panel ideal for uses ranging from high-end furniture and cabinetry to boat hulls to applications where bending is involved.

Richply D.Fir Marine AB is produced to U.S. Voluntary Product Standard PS-1 Structural Plywood and is constructed using Group 1 Douglas Fir faces, backs, and inner plies.


Richply D.Fir Marine AB is suitable for interior and exterior applications including use in high moisture applications or where appearance of one exposed surface is important. A common misconception is that Marine plywood is waterproof. The glue bond is indeed waterproof; but wood is hygroscopic and will expand and contract as it gains and loses moisture. Corresponding movement-in-service can result in panel degradation. Therefore, Marine plywood used in a wet or outdoor environment should have the panel surfaces and edges finished or sealed to stop the elements from affecting the panels.

Richply D.Fir Marine AB combines the warmth and natural beauty of Douglas Fir wood grain appearance with the structural performance; lightweight, easy to handle, strong and durable. Typical end-use applications include commercial projects, furniture, cabinetry, countertop underlayment, laminate and overlay applications, boat hulls, docks, boat houses, outdoor signs, home projects, porch ceilings, soffits, fascia, and accent panels.

Key Advantages:

  • Attractive Appearance – the premium A-grade panel face captures the warmth and natural beauty of the real wood grain features contained within the Douglas Fir species.
  • Sanded Surface – smooth, solid surface that is consistent in thickness from panel to panel.
  • Solid Core – Marine AB’s panel construction with solid core offers superior structural integrity, resistance to elements, and improved long-term performance.
  • Light Weight and Workability – excellent strength-to-weight ratio; a 3/4” panel typically weighs less than 68 lbs, is easy to work with, and can be cut into almost any shape or size.
  • Dimensional Stability – plywood’s cross-laminated construction provides excellent two-way strength and stiffness properties, resistance to impact damage, and dimensional stability when gaining or losing moisture.
  • Fastener-Holding Ability – plywood’s cross-laminated construction provides excellent fastener-holding ability; nails and screws can be placed near panel edges without splitting the panel.
  • NAUF – manufactured with no added urea-formaldehyde.
