2440 X 1220 Plywood (Softwood)

When your project demands the highest level of performance in damp or high-humidity environments, our Marine Plywood is the professional’s choice. Marine Plywood is a premium-grade structural board engineered to perform where standard plywood might fail. While it shares the cross-laminated construction of our hardwood plywood, Marine Plywood is manufactured to a much stricter standard. It is built with high-quality veneers that have minimal core gaps, significantly reducing the risk of “delamination” (the layers peeling apart) and ensuring a solid, void-free structure throughout the entire sheet. Each 2440mm x 1220mm (8ft x 4ft) sheet is bonded with high-performance weather and boil-proof (WBP) adhesives. This makes it ideal for use in areas prone to moisture, such as bathrooms, kitchens, and external applications where a superior, stable finish is required. Available in 12mm and 18mm thicknesses, this is the toughest plywood in our range. Key Benefits of Marine Plywood Superior Resistance to Delamination: Thanks to the use of high-grade veneers and a void-free core, Marine Plywood maintains its structural integrity even in humid conditions. This prevents the moisture ingress that causes standard boards to swell or split over time. Exceptional Surface Quality: Marine Plywood features a smooth, high-quality face on both sides. This uniform surface is perfect for applications where the wood will be visible, providing a professional base for high-gloss paints, varnishes, or specialised coatings. Targeted Thickness Options for Structural Success: At AG Fencing, we stock Marine Plywood in 12mm and 18mm thicknesses. This allows you to choose the exact level of rigidity needed—the 12mm is excellent for wall linings and lighter joinery, while the 18mm provides the heavy-duty strength required for high-traffic flooring, roofing, and external structural builds. Enhanced Strength and Stability: Compared to OSB or standard softwood boards, Marine Plywood offers superior screw-holding power and much greater resistance to bending. Its cross-grained construction ensures it remains dimensionally stable, refusing to warp or twist when the temperature changes.
