Accoya® Wood for Shutters and Louvres | Accoya

Accoya® wood is the result of decades of research and development that has brought together a long-established, extensively proven wood modification technique and leading-edge patented technology – acetylation to create a high-performance wood, ideal for outdoor use and challenging applications.

SPECIFICATIONS

• Durability: EN 113 Class 1 (the highest rating; comparable to the best teak). Accoya® Wood acts as an effective barrier against a broad spectrum of fungi including cellar, wet rot, dry rot, soft rot, white, brown and pore fungi. Verified by the American Wood Protection Association (AWPA) E10 test.
  
  
• Lifespan: Accoya® wood is warranted against rot and decay for 50-years above ground; 25-years in-ground/freshwater.
  
  
• Effective barrier to attack against insects and pests: Accoya® wood is indigestible by a wide range of pests and insects (including termites), resulting in an effective barrier to attack. Verified by AWPA E1 test.
  
  
• Physical Properties: Accoya® wood is high performance wood: equilibrium moisture content is significantly lower, hardness is increased, bending strength and stiffness is retained, and the thermal conductivity is reduced resulting in improved insulation characteristics: - Equilibrium Moisture Content: 3-5% - Density: 32 lb/cu ft - Shrink/Swell: 0.7% Radial / 1.5% Tangential- Janka Hardness: 922 lbf side / 1484 lbf end- Bending Strength: 12,144 psi- Bending Stiffness: 1,297,492 psi
  
  
• Fire Rating: Class C (ASTM E84) as with most woods; can be fire-retardant-treated to meet higher requirements.
  
  
• Machinability: Accoya® wood has a low moisture content, kiln-dried material that is harder than the original wood species. Accoya® wood machines more like hardwood and requires no special tools for cross-cutting, ripping, planing, routing, or drilling.
  
  
• Disposal: Accoya® wood is non-toxic, can be reused when no longer needed or can be disposed of like regular wood.
  
  
• Gluing: Accoya® wood can be glued using many commonly used wood adhesive systems. Particularly good results are obtained with polyurethane (PU), emulsion polymer isocyanate (EPI), epoxy and phenol resorcinol formaldehyde (PRF) adhesives.
  
  
• Fasteners & other Hardware: Corrosion-resistant, high-quality 304 or 316 stainless steel or naval brass fasteners are recommended. Chrome-plated, aircraft anodized aluminum or proprietary epoxy or ceramic-coated fasteners may be a suitable alternative. Zinc plated or galvanized steel is not recommended.
  
  
• Coatings: Many high quality outdoor approved wood coating systems are compatible with Accoya® wood. Leading coating manufacturers have found that the extraordinary dimensional stability of Accoya® wood allows their wood coatings to last three or more times longer.
