best wood CLT BOX Wooden box element for large spans
best wood CLT BOX consists of best wood CLT with three glued-on glulam ribs and a CLT cover panel.
The hollow box element is a statically effective and at the same time space-creating wooden element, which is suitable for any ceiling requirement thanks to its flexible dimensions and excellent structural-physical properties. By exploiting the advantages of solid timber and timber post and beam construction, an efficient and versatile building product is created.
The combination of CLT and ribbed timber results in a high static load-bearing capacity with comparatively low weight. The crosswise construction of high-quality raw material in combination with high-quality flank and surface bonding ensures a high degree of dimensional stability. A high degree of prefabrication of the best wood CLT BOX with downstream joinery and the simple connection of the best wood CLT BOX elements ensures fast and economical assembly and guarantees a dry construction method.
Advantages:
- high static load-bearing capacity with low weight
- large spans and thus column-free rooms possible
- high degree of prefabrication and simple connection of the ceiling elements for fast and economical assembly
- utilisation of advantages of solid timber and timber post and beam construction methods
