The resistance of high acetyl WPG solid timber (Accoya®) and medium density fibreboard (Tricoya®) to attack by wood-destroying fungi and termites was investigated under both laboratory and field conditions. Laboratory decay studies were conducted in Australia and New Zealand. Field studies were conducted in Australia, Japan, New Zealand, Thailand and USA. The results of the laboratory and field studies against decay fungi support previously published work showing that high acetyl WPG timber materials are highly resistant to attack by wood destroying fungi. The field studies against termites have further enhanced knowledge of the resistance of acetylated timber materials to attack by termites; it has been demonstrated that Accoya® and Tricoya® are resistant to attack by the highly destructive Australian subterranean termite species Mastotermes darwiniensis. It would be expected that Accoya® and Tricoya® would exhibit excellent long-term performance against wood destroying fungi and termites in most regions in the world.
