*As of 21 December 2018, regulations were put into effect that ban combustible materials in the external wall systems of buildings over 18m high, stipulating that materials that form part of an external wall, or specified attachments, of a relevant building meet European Classification A2-s1, d0 or A1.
This means that timber construction systems, such as CLT, will need separation between the structure and the outer face of a building over six storeys high. A number of ways to achieve this can be considered, without compromising the integrity of the CLT structure. This does not affect timber frame systems, which are suitable for lower-rise buildings.
