Because they are delivered with a low moisture content, structural elements in cross laminated timber (CLT) can be enclosed immediately. Elements in other materials may need to dry out before being enclosed. The moisture issue always needs to be addressed, but the method varies for different construction materials.

It is going to rain and maybe even snow during the construction process. The CLT elements are going to be exposed to moisture. But with the right handling, this needn’t be a problem.

The publication focuses on various parts of the building, critical details and connections. It gives examples of how these can be damp-proofed an d how the structural design can contribute to efficient construction in CLT.
