Long lasting Plywood Types of Plywood like Hardwood Plywood and Veneer Associations (HPVA) defines Hardwood plywood as a manufactured panel made up of three or more thin plies of hardwood (ie. red oak), laid on top of each other, with the grain of each ply running perpendicular to the one on either side of it. Plywood offers a strong, inexpensive, and environmentally responsible alternative to its solid wood counterparts.
Long lasting Plywood like substrate such as Veneer Core, MDF, or Particleboard are typically faced with hardwood species, including cherry, walnut, ash, white oak, red oak, birch, maple, mahogany, rosewood, teak, and a large number of other species. Decorative hardwood plywood is generally used for cabinets, wall-paneling, furniture, and mill-work.
Marine plywood is manufactured from durable face and core veneers, with few defects; so it performs longer in both humid and wet conditions and resists delaminating and fungal attack. Its construction is such that it can be used in environments where it is exposed to moisture for long periods. Each wood veneer will be the same species throughout (Fir, Okoume, and Meranti), and have minimal core gap, limiting the chance of trapping water in the plywood and hence providing a solid and stable glue bond. It uses an exterior Water and Boil Proof (WBP) glue.
Okoumé and Meranti Marine plywood can be graded as being compliant with BS-1088 or BS-6566, which is a British Standard for marine plywood. Some marine plywood has a Lloyd’s of London stamp that certifies it to be BS 1088 or 6566 complia
Marine Fir AB is marine-grade plywood that is produced entirely of Fir veneers. The Panel is sanded on both faces. The maximum core-gap size permitted is 1/8 inch. Its exposure durability rating is EXTERIOR and the glue used is a water resistant structural adhesive. It is considered a premium grade panel for use in situations where these characteristics are required.
Marine plywood is frequently used in the construction of boats, docks, outdoor signs, counter top underlayment, and anywhere that requires prolonged exposure to outdoor elements.
