Product Overview
Exterior Grade Class 3 Hardwood Plywood with a 12mm thickness. A premium, high-performance sheet material designed for outdoor and high-moisture environments.
Manufactured from selected hardwood veneers and bonded with a Class 3 weather- and boil-proof adhesive, it provides exceptional durability, dimensional stability, and resistance to fungal decay. This plywood maintains structural integrity under prolonged exposure to moisture and fluctuating weather conditions, making it ideal for light to medium-duty exterior and semi-exposed applications.
The smooth, even surface accepts paints, stains, and protective coatings, ensuring both functionality and aesthetic quality. The 12mm board thickness offers a lighter, easier-to-handle sheet suited to general-purpose linings, sheathing, and protective panelling rather than heavy load-bearing structures.
Features & Benefits
- Exterior-grade construction: Engineered with Class 3 adhesive for superior resistance to weather and humidity.
- High-strength hardwood core: Provides outstanding mechanical performance and dimensional stability.
- Weatherproof durability: Withstands continuous exposure to moisture without swelling, delaminating, or warping.
- Smooth surface finish: Ideal for paint, stain, or laminate applications where a clean, uniform appearance is required.
- Fungal and moisture resistance: Prevents decay and surface degradation in damp or outdoor conditions.
- Lightweight versatility: Reduced board thickness makes handling and installation easier while maintaining strength.
- Board thickness 12mm: Best suited to wall sheathing, general construction, and protective or non-structural uses.
Applications
- Flooring: Provides a robust and moisture-resistant base for both permanent and temporary floor structures.
- Roof decking: Suitable for lighter roof structures or small-span coverings.
- Floor overlays: Appropriate for non-structural or secondary flooring layers where reduced thickness is required.
- Site hoardings: Reliable choice for durable, reusable site barriers and screening panels.
- Temporary protection: Effective for safeguarding floors and structures during construction or refurbishment.
Installation Guidance
- Panel conditioning: Allow sheets to acclimatise to site temperature and humidity before installation.
- Fixing method: Secure with corrosion-resistant screws or nails at recommended centres for exterior-grade boards.
- Joint spacing: Leave small expansion gaps between sheets to accommodate natural timber movement.
- Edge treatment: Seal cut edges and faces with a waterproof coating or paint for extended durability.
- Surface finishing: Apply appropriate protective or decorative finishes depending on exposure level and application.
Compliance & Performance
- Material specification: Multi-ply hardwood veneers bonded with Class 3 (EN 314-2) weather and boil-proof adhesive.
- Durability rating: Certified for exterior use under EN 636 Class 3 performance standards.
- Weather and moisture resistance: Suitable for continuous exposure to outdoor conditions.
- Fungal resistance: Designed to prevent biological degradation under damp or humid environments.
- Important note: Ensure all edges and penetrations are sealed to maintain full exterior-grade performance.
