Plywood for marine and humid interiors
True marine plywood (BS 1088, etc.) is a certification and glue-line category—not a generic export description. For humid interiors, specify WBP glue, acceptable species, and test evidence appropriate to your class society or building code.
Due diligence
Do not assume all “marine plywood” claims are interchangeable. Request mill certificates and, where required, third-party test reports.

▶What thickness of plywood is used for marine interior?
Thickness depends on span, finish system, and local code or OEM requirements. Browse our thickness-specific spec pages or use calculators with your engineer’s design values.
▶How do I estimate container loads for a project?
Start from sheet count and thickness, then use the container packing calculator with your core density and panel size.
