These 15mm marine-grade plywood sheets are built in line with British Standard BS1088. They are pressed from untreated tropical hardwood veneers and bonded with Weather and Boil Proof (WBP) adhesive, giving them long-lasting durability and reliable resistance against moisture and challenging weather conditions.
Our range covers sizes from 12"x12" through to full 8'x4' (approx. 300 x 300mm to 2440 x 1220mm). This flexibility makes ordering straightforward whether you need small cut panels or full-size boards for marine, exterior, or structural projects.
Marine Plywood Features
Manufactured to BS1088 with WBP adhesive for strong moisture resistance.
Multi-layered hardwood veneer build with a smooth face and stable core.
Void-free interior for improved load-bearing and reduced risk of delamination.
Sustainably sourced hardwood from managed forestry resources.
Performs well in wet or humid conditions with repeated exposure to moisture.
Standard 8′x4′ sheet provides approx. 2.98m² coverage.
Average board weight approx. 27kg depending on species.
Note: final sheet dimensions may vary slightly due to saw blade cutting loss.
How does marine plywood differ from standard plywood?
Marine plywood is engineered with many thin hardwood layers for strength and uniformity. Standard plywood often uses fewer, thicker softwood layers such as pine or Douglas fir. This difference makes marine plywood denser, harder, and more suitable for outdoor or structural use where resistance to moisture and strength are critical.
Is marine plywood fully waterproof?
The sheets themselves are not waterproof, but the WBP adhesive prevents the veneers from separating in damp or wet environments. This quality allows marine plywood to be used in exterior joinery, marine construction, outdoor furniture, and in coastal settings with high natural humidity.
Should marine plywood be treated?
Yes. While the adhesive is waterproof, sealing the faces and edges will extend the service life. Treatment ensures the sheet resists decay and maintains stability during long-term use.

FAQ
All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
Most orders arrive within 3-4 days, the maximum is 7 days. Please get in touch before you order if you need a specifc delivery date.
Delivery charges vary by postcode. To find out the delivery charge, add the item(s) you require to your basket and select CALCULATE SHIPPING at the bottom of the page.
Some orders are delivered on our own vehicles based in Leicestershire and Cheshire. We also use carriers including Yodel and Tuffnells. For some sizes and locations we use regional distributors.
If you'd prefer crane offloading rather than tail lift vehicle offloading for your brick order then this service is available for the majority of bricks that we sell. Charges are shown at checkout.
For deliveries of less than 6 packs then Taillift offloading is normally a more cost effective option
