A wide range of glues is permissible for use in cross laminated timber. Nowadays, however, gluing of cross laminated timber elements available on the market is carried out exclusively using two glue types (PUR, MUF). The advantages of these gluing systems can be found in the rapid hardening times and transparent glued joints.
The glued joints are extremely thin (between 0.1 and 0.3 mm), and the glue is extremely insensitive to chemical influences. Cross laminated timber manufacturers usually only use one type of glue for surface gluing.
