Fixing and buying guide
12mm x 2440mm x 1220mm Marine Plywood
Measuring and calculating sheet requirements
Marine plywood sheets measure 2440mm long by 1220mm wide. Measure your project area and plan cuts to minimise waste. For rectangular panels, divide your total area by the sheet area (2.98 m²) and round up. Account for saw kerf loss (typically 3-4mm per cut) when planning multiple pieces from one sheet.
- Each sheet covers approximately 2.98 m²
- Standard sheet dimensions: 2440 x 1220mm
- Plan cuts before purchase to reduce waste
- Allow for saw kerf when cutting multiple pieces
Thickness selection and structural use
The 12mm thickness provides good structural rigidity for boat building, external cladding, and moisture-prone applications. It is thicker than standard 9mm plywood, offering greater load-bearing capacity and resistance to deflection. Confirm thickness requirements with your project specification or structural engineer if load-bearing performance is critical.
- 12mm thickness suitable for structural and non-structural applications
- Provides rigidity for boat building and external cladding
- Greater deflection resistance than thinner grades
- Verify thickness requirements for your specific application
Storage and handling before use
Store marine plywood flat and off the ground in a dry location. Protect sheets from direct rain and prolonged exposure to damp air before installation. Although marine plywood resists moisture, the cut edges and face surfaces can absorb water if left unprotected for extended periods. Stack sheets horizontally with spacers between them to allow air circulation.
- Store flat and off the ground
- Keep in a dry location until installation
- Protect from rain and prolonged damp exposure
- Use spacers between stacked sheets for air circulation
