Product Overview
BS1088-certified marine-grade plywood sheet, measuring 2440mm x 1220mm (8' x 4') with a 25mm thickness.
Made from durable tropical hardwood veneers and bonded with waterproof adhesive, it resists swelling, warping, delamination, and rot even under prolonged moisture exposure.
Unlike standard plywood, it contains no core voids, preventing water entrapment and improving overall strength.
Widely used for structural floors, bulkheads, and high-load marine or outdoor projects, the solid hardwood face is pre-sanded and can be left natural, stained, or varnished.

- Rot resistance: Designed for extended service life in damp or wet environments.
- Impact resistance: Strong veneer lay-up withstands heavy use and knocks.
- Workability: Easy to cut, drill, and shape with woodworking tools.
- Standard sheet size (2440mm x 1220mm): Covers 2.98m² per sheet, minimises waste.
- Thickness 25mm: Heavy-duty board for structural floors, bulkheads, and high-load marine applications.
Please Note: Colour and finish are representative only and may vary slightly as this is a natural product.
