How delivery works

We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.

Delivery areas

Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.

If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.

What to expect on delivery day

  • Deliveries are typically kerbside.
  • Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
  • Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.

Why delivery can cost more than typical parcel delivery

Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.

Returns

Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.

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.
