Marine plywood manufactured under the EWPAA Quality Control and Product Certification scheme to Australian/New Zealand Standard AS/NZS 2272 Plywood – Marine has been designed specifically for structural applications where high impact resistance and high quality face finishes are required (which is why it is very popular in applications such as boat hulls). Marine plywood possesses the following characteristics: Bond Type A (phenol formaldehyde) which is dark in colour. The A bond is completely durable under a marine environment. Stress Grade F14. Marine plywood has known structural performance. Species are chosen on the basis of bending strength and stiffness, impact resistance, density, dimensional stability, glueability and paintability. The arrangement of veneers in the plywood is limited also to provide two way panel strength, stability and impact resistance. Face Grade Marine plywood is manufactured with A grade veneer on both the face and back. The natural wood characteristics are limited by both structural and aesthetic considerations. Marine plywood can be painted or clear finished on both surfaces.
We also source BS 1088 Marine Plywood which is the British Standard specification for marine plywood that applies to plywood produced with untreated tropical hardwood veneers that have a set level of resistance to fungal attack. The plies are bonded with Weather Boil Proof (WBP) glue.
Although this is a British Standard, the finished product does not have to be made in Britain, just manufactured to meet the standard. The standard is associated with Lloyd's Register since it performs testing of products to this standard. It does not follow that it is a structural plywood.
WBP Glue Line-- BS 1088 plywood must use an adhesive, which has been proven to be highly resistant to weather, micro-organisms, cold and boiling water, steam and dry heat. The product's bonding must pass a series of British Standard tests.
