Product Overview
Exterior Grade Class 3 Hardwood Plywood with a 9mm thickness. A high-quality, weather-resistant sheet material designed for light exterior, semi-exposed, and general-purpose applications.
Manufactured from selected hardwood veneers and bonded with a Class 3 weather- and boil-proof adhesive, it provides durable resistance to moisture, temperature variation, and fungal growth. The thinner profile offers excellent flexibility and easier handling, making it well-suited to protective cladding, sheathing, and decorative outdoor uses rather than heavy structural installations.
Its smooth, uniform surface allows high-quality paint, stain, or laminate finishes. The 9mm board thickness delivers stability and resilience where reduced weight and adaptability are key performance factors.
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 9mm: Optimised for light-duty construction, panelling, and temporary or non-load-bearing installations.
Applications
- Wall and ceiling linings: Provides a neat, stable surface for finishing or protective use in damp environments.
- External cladding: Suitable for light cladding or fascia panels exposed to weather intermittently.
- Soffits and eaves: Ideal for undersides of roof overhangs requiring moisture resistance and low weight.
- Hoardings and barriers: Effective for short-term or transportable protection structures.
- Decorative or functional panelling: Used in garden buildings, sheds, or interior fit-out projects.
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.
