Teknologisk Institut (DTI) has published a summary report consolidating and summarizing tests and documentation on Superwood. Read the report here
In order to investigate the woods resistance to biodegradation, Teknologisk Institut (DTI) exposed differently untreated and treated wood for an accelerated process in the tropical climate in Malaysia.
The test results from Malaysia indicate that fully impregnated spruce from Superwood will survive at least 30 years in temperate climates such as Denmark, if the tree is not in contact with the ground. Unprotected spruce has in comparison a lifetime of 5-10 years with the same implications.
