best wood CLT – CEILING XL Cross laminated timber for solid ceiling constructions
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 layer structure of high-quality raw material provides a high degree of dimensional stability, and leads to only small amounts of swelling and shrinking in the panel level in the event of moisture changes.
A high degree of prefabrication of the best wood CLT with downstream joinery and the simplicity of joining the best wood CLT elements ensures swift and cheap installation and guarantees dry construction.
Static and fire protection verification can be easily produced using the best wood STATICS software.
