Marine Plywood Wikipedia

Marine plywood is a very wide definition of a plywood range. There are many types of ply in the market but there is a specific type of plywood that can be defined as marine grade. The definition can be different.

Marine Plywood By ‘Waterproof’

When we say a plywood is marine grade means it is weather and boiling proof. In this case, marine plywood = wbp plywood. The wood panel can stay in exterior under rain for long time. Even the weather becomes dry and wet again, the plywood won’t delaminate.

Even the film faced plywood can be marine plywood. Why? Because many film faced plywood are produced with wbp melamine or wbp phenolic glue. The middle east countries usually name their film-faced plywood as marine plywood or marineplex.

Maritime Marine Plywood

When we talk about plywood used for maritime, the plywood narrowed to a very small range. In short words, maritime marine plywood is void-free plywood with thick face veneers. Of course, WBP phenolic glue are used for its production.

BS 1088

BS 1088 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.

BS 6566

BS 6566 is very similar to BS 1088 with a somewhat reduced quality. It is a marine plywood standard using the same glues but has a lower requirement for the quality of the veneers. The face veneers are often of slightly lower grade and thinner. There are no voids and requirements for joins are similar. It is generally considered an excellent material if not as pretty as the higher grade. Bright finishes are not necessarily as successful as with the BS 1088.

AS/NZS 2272

This is an Australia / New Zealand standard. Marine Plywood manufactured to AS/NZS 2272 standard, is a structural plywood intended for hulls of boats and other marine applications. It has a Type A (wbp) phenolic bond glue and is manufactured from woods based on density, bending strength, impact resistance and surface finishing characteristics. None of the marine species are naturally durable and preservative treatment will be required. Hoop pine is often used in Australia.

Marine Plywood Material

The marine plywood is rarely left unfinished. It very often has an epoxy coating, often with glass cloth as well. Gaboon Okoume is a prime example of a widely used plywood wood which is not particularly resistant to rot and fungus. You may not always need the best grade of plywood. Often a high-end exterior ply will do as well particularly in areas.

What is the main difference between marine plywood and ordinary plywood?

Marine plywood has no core voids.

Is marine plywood waterproof?

No plywood is waterproof. But marine plywood can resist the humid very well thanks to its phenolic glue and great core.
