New research has shown that Accoya modified wood is more durable than teak and CCA-treated wood.
Scion, formerly known as the New Zealand Forest Research Institute, conducted several fungus decay chamber and exterior ground tests on Accoya, merbau, cedar, teak and cypress, as well as CCA-treated timbers.
It found that after five years’ exposure in the chambers and in the ground, Accoya was in much better condition than the other samples.
After 60 months, all Accoya stakelets were in good condition, with just two showing signs of minor decay, while three of the CCA-treated samples had failed and the remaining were in poor condition.
Cypress scored 3 out of 10, cedar 5, and Accoya 9.8.
Accsys Technologies, which owns the Accoya business, said the research shows that the product can be used for a wider range of applications than the current joinery, cladding, decking and external beam uses.
