Summary

This revision includes an additional supplier in Table 2 only.

The technology and market for cross-laminated timber (CLT) is changing rapidly. 2015 sees the introduction of CE marking of CLT panels according to the product Standard BS EN 16351 published in October 2015. This general revision includes an amended sections on durability and thermal performance.

Although cross-laminated timber (CLT) originated in Continental Europe, it is increasingly popular in the UK. CLT panel construction is now used with confidence to challenge concrete and steel frame construction in tall and long span applications where conventional timber framing was hitherto unsuitable or uneconomic.

This Wood Information Sheet (WIS) is an overview of the subject with signposts to more detailed sources that are listed at the end. It highlights all the design issues that specifiers should consider with the exception of structural aspects which are covered in the companion sheet WIS 2/3-62: Cross-laminated timber: structural principles.

Key Information

Cross-laminated timber is now being considered where masonry, concrete and steel have historically been the usual forms of construction.

These large solid structural panels form walls, roofs, floors, and even lift shafts and stairs.

Due to the large amount of CO2 absorbed and stored in the wood, CLT systems offer enhanced sustainability performance.
