I ordered 18 of the 40mm Soprema PIR Insulation Boards (1200 x 2400mm), and I couldn’t be happier with the service. Delivery was super fast, and everything was delivered with great care. The online ordering process was easy and straightforward, and the communication afterwards was absolutely fantastic. I honestly cannot fault anything. Excellent service, great communication and a smooth, hassle-free experience from beginning to end. Highly recommended! I would definitely order from them again.

Outstanding service from Trade Insulations. Ordered Rockwool slabs for a floor/ceiling project, and the delivery was bang on schedule. ​The insulation density is so impressive I’m tempted to line my entire life with it. James messaged to check in on the delivery, proving they care as much about customer satisfaction as they do about acoustic decibel reduction. Absolute legends. Don't bother looking anywhere else

18mm Marine Plywood

When it comes to strength and exceptional resistance to moisture, 18mm Marine Plywood is the top choice. This robust structural sheet material is specifically designed to withstand water damage, making it highly popular for boat building applications. Its core, which boasts high moisture resistance, sets Marine Plywood apart as a premium load-bearing solution. While it earned its name from its widespread use in shipbuilding, Marine Plywood also proves its worth in various construction applications where rigidity and stability are vital, such as flooring, roofing, and wall applications. Unlike regular plywood, Marine Plywood is crafted with waterproof glue, significantly reducing the risk of swelling or delamination when exposed to moisture.

18mm Marine Grade Plywood Applications

When you require impeccable moisture resistance for both interior and exterior applications, including flooring, roofing, walls, general joinery, and external joinery, rely on 18mm Marine Grade Plywood. This outstanding product is built to endure, delivering unwavering performance even in damp weather conditions. Unlike moisture-resistant MDF, Marine Plywood is designed to withstand immersion in water without compromising its performance.

While it excels in structural use within properly protected specifications, conforming to BS1088 (the British standard specification for Marine Plywood), this plywood is also suitable for the following applications:

  • Shop fitting
  • Storage boxes
  • Bathrooms
  • Sheds
  • Walkways
  • Kitchens
  • Patios
  • Indoor vehicle storage areas
  • Roof supports
  • Cold frames

For aesthetic applications like shelving, we recommend sanding and applying a layer of varnish to enhance its appearance.

Key Features of 18mm Marine Plywood (2440mm x 1220mm)

18mm Marine Grade Plywood offers numerous benefits by utilising highly durable timber species that resist decay in water-based applications. This structural composition makes Marine Plywood highly regarded in the boatbuilding and marine insurance industries, as it provides unbeatable weatherproofing and maintains its structural integrity over extended periods in wet conditions. While naturally resistant to moisture, you can further increase the service life of Marine Plywood by sealing both the edges and faces of the sheets.

Let’s explore the key specifications:

  • Moisture resistant: Retains its integrity when in contact with water
  • Suitable for flooring, roofing, and wall applications
  • Holds laminate, paint, and polish well
  • Pliable design: Can bend without cracking or compromising structural integrity
  • Offers superior impact resistance
  • Void-free structure enhances structural soundness

Marine Plywood is made from solid veneer wood, resulting in a finished surface with a natural wooden appearance. Thus, actual product images may slightly differ due to variations in colour and grain.

18mm Marine Grade Plywood Size

18mm Marine Grade Plywood comes in a sheet size of 2440mm x 1220mm x 18mm, covering an area of approximately 2.98m2.

Manufacturing Process of 18mm Marine Grade Plywood

While standard plywood sheets consist of layers of softwood and hardwood, Marine Plywood is manufactured using multiple layers of water-resistant tropical hardwood bonded together with waterproof glue.

Unlike standard plywood, Marine Plywood is free from air pockets and core voids, significantly reducing the likelihood of water seepage between the layers. If you were to cut through a regular plywood sheet, you would notice holes and voids within the layers. By avoiding these gaps, Marine Plywood exhibits greater structural integrity and resistance to rot, making it ideal for demanding applications where exposure to the elements is expected.

Both the quality and lay-up of the veneers in Marine Plywood contribute to its exceptional strength and resilience.

How to Cut Marine Plywood

Despite its strength, cutting Marine Plywood is a straightforward process. Simply use a jigsaw and cut along the grain lines to achieve a smoother cut.

Colour and Finish Disclaimer

Please note that the colour and finish of Marine Plywood may slightly vary as it is a natural product.
