From innovate treatments that improve the durability of timber and timber products, to new products designed for specific applications and connections that reduce assembly time and costs, this is an invaluable resource.View
TITAN Wood/Accoya – Chemically modified wood
Acetylation protects wood by actually changing its chemical structure: wood technologists describe the effect of acetylation as being analogous to effectively creating a “new wood”. They argue that acetylated wood should be considered by consumers as an entirely new species, so different are its properties from the underlying species from which it is made. Durability can be “upgraded” to the durability of the most durable hardwoods, the swelling and shrinking due to the change in moisture content is reduced dramatically.
The principle benefits are the increase in natural durability and the reduction in shrinkage and swelling, which increases the lifetime of finishes and broadens the scope of appliaction of certain timber species.
Limitations are in the field of structural use. Limited research carried out on elements of structural sizes show some reduction in strength properties at the characteristic level.
Any product or system that can markedly improve the durability and stability of wood at an economical cost and without the need for 'preservative' chemicals, should have significant potential.
Structurecraft are a contractor specialising in the engineering, design detailing, supply and fabrication of complex, large and challenging timber structures. Though there is nothing especially groundbreaking about the panelized systems that they use, they occupy a worthwhile link in the supply chain that largely does not currently exist...
