ACCOYA - Wood without compromise Guarenteed to last 30+ years
Accoya is the world's leading high technology long life wood. Created via acetylated wood modification, using sustainably grown timber, the Accoya process is non-toxic. It enables nature and creates a modified wood that matches or exceeds the durability, stability and beauty of the best tropical hardwoods.
The Accoya wood production process takes sustainably-sourced, fast growing softwood and in a non toxic process that 'enables nature', creates a new durable, stable and beautiful product, a 'treated timber' that has the very best environmental credentials.
A new world of high performance wood, sustainable, low maintenance products - including windows, doors, decking, cladding and glulam structural beams - is opened up by Accoya wood. The exceptional properties of durability, stability, strength and beauty have even led to Accoya wood being used as the main construction material in a heavy traffic road bridge with highly original design.
Accoya is helping to protect the worlds precious hardwood resources and is guaranteed for 50 years in exterior use and 25 years when used in the ground. Yhis long life also provides an added benefit - helping to reduce carbon emissions.
Accoya is ideal for windows, doors, cladding, decking, structural and much more.
For window frames, Accoya wood is the material of choice. Not only does it have extremely low thermal conductivity but it matches or exceeds the durability and dimensionally stability of the best hardwoods. It can be opaque coated, or for those wishing to enjoy the natural look of wood, translucent coated. Accoya's low maintenance requirements add to its cost effectiveness and environmental credentials.
Exterior doors and shutters should be durable, dimensionally stable(to prevent doors jamming and becoming difficult to open and close in bad weather) and easy to maintain. Accoya wood meets these criteria and may be used to create simple or complex designs with a choice of coating finishes with typically greatly improved lifetimes.
Accoya wood is a perfect solution for exterior cladding, siding and facades where aesthetics, less frequent maintenance, durability and insulation value are key factors. Accoya's versatility makes it ideal for use in residential, commercial and industrial structures.
In specifying decking, beauty, strength and all weather performance are important. A material that is durable, stable and beautiful is desirable. It is also crucial that the wood is non-toxic and therefore totally safe for people and pets. Accoya wood meets these requirements.
Accoya wood has been modified right through to the core and this non-toxic process doea not weaken the origianal wood - in fact, its hardness is improved - nor does it compromise its bending strength. Therefore combined with exceptional durability and stability Accoya wood can be an ideal material for structural requirements and has been used in bridges and other large structures around the world.
Against a backdrop of growing concern about the environmental impacts of the things we do and the materials we use the popularity of wood - a versatile, beautiful material that's easy to use and to live with - is set to increase. It's not just good looks and charm that will ensure that wood plays a leading role in our future, but a number of other factors too:
- ~ Wood is a non-toxic, recyclable raw material.
- ~ Wood is light yet strong and easily worked.
- ~ Wood offers good sound absorbtion.
- ~ Wood can be used as a bio fuel at the end of its product life.
- ~ Wood is our only truly sustainable resource for construction.
- ~ Wood is a natural insulator and, as such, reduces energy used for heating.
- ~ Wood reduces the effect of global warming as trees and wood products act as carbon sinks.
- ~ Wood is sustainable and healthy: every cubic meter used saves tonnes of CO2.
By using sustainably grown wood and improving its properties without adding toxins, Accoya helps protect threatened species, rainforests and the environment.
OUTSTANDING PERFORMANCE
Extensive laboratory and field testing by leading institutes around the world (including New Zealand, USA, UK, Sweden, Malaysia, Indonesia, Russia, the Netherlands and Japan) has shown the performance of acetylated wood is extremely reliable.
Accoya wood has been thoroughly tested for dimensional stability, durability, UV resistance, paint retention and in-ground conditions to ensure optimal performance. Indeed, it is so reliable that for many years it has been, and continues to be, used by scientists as the bench mark against which other treatments and modifications are measured.
