2440 x 1220 x 18mm Brazilian Elliottis Structural Pine Plywood CE2+ Class 3 C+/C EN314-2 EN636-2S EN13986EN13986
What this product is and who needs it
This is structural plywood designed for load-bearing applications where strength and stability matter. The CE2+ classification and EN636-2S standard indicate it is suitable for use in humid conditions and structural roles. It is ideal for builders, contractors, and serious DIY customers working on house extensions, new builds, roof decking, floor joists, and wall sheathing. The E1 glue specification means low formaldehyde emission, making it suitable for internal and external use.
- 18mm thickness provides good strength-to-weight ratio for most structural applications
- 2440 x 1220mm sheet dimensions are standard metric sizes compatible with UK building practices
- Suitable for walls, floors, roofs, and general structural work
- Low emission E1 glue meets modern environmental standards
Compatibility and sizing
Each sheet measures 2440mm long by 1220mm wide, which aligns with standard stud spacing (typically 400mm, 600mm, or 1200mm centres). The 18mm thickness is commonly used for structural applications where deflection control and load capacity are important. Check your design specification or building control requirements to confirm 18mm is appropriate for your application; thinner sheets (9mm or 12mm) suit non-structural uses, whilst thicker sheets (21mm or 25mm) are needed for heavy-load applications. Ensure your supporting structure (joists, studs, or rafters) is properly spaced and sized to support plywood loads.
- Verify sheet thickness matches your structural design and building control approval
- Confirm supporting frame spacing is compatible with 2440 x 1220mm sheet dimensions
- Check moisture conditions at the site; this product is rated for humid environments but should not be left exposed to weather before installation
- Allow sheets to acclimatise to site conditions for 24-48 hours before fixing
Pre-installation checks and preparation
Before you fix the plywood, inspect each sheet for damage, warping, or delamination. Store sheets flat and dry on site, protected from rain and direct sunlight. Ensure the supporting structure is square, level, and properly braced. Check that all fixings (nails, screws, or adhesive) are specified for plywood and suitable for the intended application. If the plywood will be exposed to weather or high moisture (such as on a roof before weatherproofing), plan your installation schedule to minimise exposure time.
- Inspect sheets on delivery for damage or moisture ingress
- Store flat, dry, and protected from weather until installation
- Confirm supporting frame is square, level, and adequately braced
- Use fixings specified for plywood structural applications
- Plan installation to avoid prolonged weather exposure
Pack contents and ordering
This product is sold as individual sheets measuring 2440 x 1220 x 18mm. Calculate the number of sheets needed by dividing your total coverage area by the sheet area (approximately 2.98 square metres per sheet). Add 5-10 percent extra for cutting waste and site damage. If you are ordering multiple sheets, confirm delivery arrangements as plywood is heavy and requires appropriate handling equipment.
- Each sheet covers approximately 2.98 square metres
- Order whole sheets; partial sheets must be cut on site
- Add 5-10 percent waste allowance to your calculation
- Arrange suitable delivery and handling for heavy loads
