Product description best wood CLT – CEILING

Best wood CLT is a load-bearing solid wood element, consisting of at least three layers of crossways glued solid wood boards, which is suitable for all building requirements thanks to its excellent construction characteristics. The crosswise structure of high-quality raw material in combination with high-quality of gluing of edges and sides guarantees a high degree of dimensional stability, and leads to only small deformations from swelling and shrinking in the event of moisture changes in the panel level. A high degree of prefabrication of the best wood CLT with downstream cut-off and the simplicity of joining the best wood CLT elements ensures swift and cheap installation and guarantees dry construction. It is simple to produce building element constructions with increased fire resistance with evidence from the best wood STATICS software.
