best wood CLT – CEILING Cross laminated timber for solid ceiling constructions
The best wood CLT is a solid wood element for load-bearing purposes. It consists of at least three layers of cross-glued solid wood panels. Due to its excellent structural-physical properties, it is suitable for any structural requirement.
The crosswise construction in combination with high-quality flank and surface gluing ensures a high degree of dimensional stability and only leads to minor swelling and shrinkage deformations in the case of moisture changes in the panel plane.
A high degree of prefabrication of the best wood CLT with downstream joinery as well as the simple connection of the best wood CLT elements ensures fast and economical assembly.
