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
- Available Dimensions
Dimensions 4/4, 5/4, 6/4, 8/4, 10/4, and 12/4 Lengths 7’10”, 9’10”, 11’9”, 13’9” and 15’9”
- 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
- Effective Barrier to Attack Against Insects and Pests
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
High-performance wood: equilibrium moisture content is significantly lower, hardness is increased, bending strength and stiffness are 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
Low moisture content, kiln-dried material that is harder than the original wood species. Machines more like hardwood and requires no special tools for cross-cutting, ripping, planing, routing, or drilling
- Disposal
Non-toxic, can be reused when no longer needed or can be disposed of like regular wood
- Gluing
Any 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
