Specifications

Marine Plywood, as the name suggests, is a highly durable structured board heavily used in the marine and boat industries due to its high moisture resistant core. This core makes this particular Plywood extremely resistant to expansion and rotting, further backed up by the fact that these boards are BS 1088 certified. These boards are manufactured from bonded veneers and the edges are glued with Phenolic Resin, ensuring ultimate durability and moisture resistance.
Aside from its use in the marine industry, Marine Plywood is also ideal for use in external joinery, shelving and temporary structures.
