PLEASE NOTE: Full size sheet materials (2440mm x 1220mm & 1525mm x 1525mm) are only available for local delivery or collection - as these are too large to be dispatched by courier.

This plywood panel is manufactured and assessed in accordance with recognised European Standards, providing excellent strength, durability, and moisture resistance for demanding construction environments.

The panel is produced to EN 636-3S (structural plywood for exterior conditions) and EN 314-2 Class 3, confirming suitability for use in high-moisture and exposed applications where long-term performance is required.

Standards & Compliance

• EN 636-3S – Structural plywood for use in exterior conditions
• EN 314-2 Class 3 – Bonding quality suitable for exterior and marine-type environments
• Phenol formaldehyde (WBP) bonding
• Formaldehyde emission class E1
• Assessed under EU Regulation No. 305/2011

These standards confirm a high-performance exterior plywood panel suitable for structural applications.

Structural Performance

• Bending strength
  o Major axis: Class F20
  o Minor axis: Class F25
• Bending stiffness (Modulus of Elasticity)
  o Major axis: Class E50
  o Minor axis: Class E60
• Strong bonding performance tested to EN requirements

This ensures reliable load-bearing capability and dimensional stability in construction use.

Durability & Environmental Performance

• Suitable for exterior conditions
• High resistance to moisture and environmental exposure
• Biological durability: Class 1 to 3
• Thermal conductivity: 0.13 W/m·K
• Airborne sound insulation: 24.12 dB

The panel is designed for long-term durability when correctly installed and protected. 

Recommended Uses

This plywood panel is best suited for:

• Boat interiors and non-certified marine applications
• Exterior wall sheathing
• Roofing and decking sub-structures
• Flooring and mezzanine decks
• Agricultural buildings
• Sheds, workshops, and outbuildings
• General structural construction where moisture resistance is required

Note: While suitable for demanding exterior environments, this product is not certified to BS 1088.

Installation & Edge Sealing (Important)

For external or high-moisture applications, all exposed edges must be sealed prior to final installation.

• Seal edges with an appropriate edge sealer, paint, resin, or waterproof coating
• This significantly improves moisture resistance and extends service life
• Failure to seal edges may compromise long-term performance
