Wood protection

Cross laminated timber elements may only be utilised in the use-class (UCL) 1 or 2 ≤. With the wood moisture u 20% to be expected in the UCL 1 and 2 an infestation from wood destroying fungi can be excluded.
Recent findings concerning basic insect insensitivity to technologically seasoned glue laminated timber in the UCL 1 and 2 are, on the basis of the similar manufacturing process, also applicable to cross laminated timber. It can be assumed that the revised DIN 68800-1 "Wood protection for cross laminated timber", to be completed in the near future, will exclude an insect threat in the UCL 1 and 2.
