Cross-laminated timber construction - an introduction
www.structuraltimber.co.ukconstruction. Table 1 indicates some typical characteristics of different forms of large-volume engineered wood panel products. Large-volume timber structures, such as CLT, are a natural choice of construction where low-embodied-carbon materials are required for where the aesthetic requirements for a dimensionally stable exposed timber finish are
CROSS-LAMINATED TIMBER - BRE
www.bre.co.ukAs an engineered timber product, with the cross-grain movement controlled by the cross-lamination, it is broadly dimensionally stable and shrinks less than standard solid timber construction. While it is usable on small projects, it is more often used on larger schemes where offsite manufacture and speed of construction can reduce costs.
