Although the wood technology is popular in Europe for building, it has only recently begun to gain acceptance in Britain.
Cross-laminated timber may be a mouthful to say, but it is a fast-becoming a much talked about material in professional construction circles.
CLT is produced from industrially dried, quick growing spruce (larch or pine are alternatives) boards, stacked at right angles and glued together over their entire surface in generally 3, 5, 7 or more board or panel layers. The majority of CLT is manufactured in Austria and imported to the UK.
The panels are used as large external and internal wall, floor, ceiling and roof elements. They are factory manufactured with precision cut-outs for doors, windows and building services. Delivered to site in prefabricated form, they are slotted into place in situ.
