Cross Laminated Timber (CLT) is a wonderfully versatile building material, that can be used for external and internal walls, intermediate ceilings, and as roof panels in conjunction with other building materials. The number of CLT layers is always odd – 3, 5 or 7 layers (except some special cases - 9 layers).
Layers, with moisture content 12 +- 2%, provide a so-called locking effect, which ensures very good stability of the panel measurements, stability during changes in humidity and significantly reduces negative effects of wood drying. CLT has no architectural constraints, and because of this, more and more CLT is being used for building private houses, apartment buildings, as well as industrial and commercial buildings.
The use of CLT in bridge building has become more and more popular. Its large format elements accelerate the construction process greatly. Fixings between panels are made quickly for screws, bolts, and pins, and do not require any extra drying time.
