The solid wood cross section of CLT in wall and ceiling has great advantages compared to light construction methods such as frame walls or beamed ceilings in terms of fire and sound protection and allows for high-quality visible wood surfaces. Because the calculated production waste, which can vary anywhere from 10 to 20 percent, increases production costs, the reuse of large amounts of production waste offers great potential to improve the efficiency, competitiveness, and environmental performance of the material. The usual thermal utilization with minimal added value simply cannot compensate for this. The aim of this particular project is to develop a structural system of elements specifically tailored for their intended use only. At present, work is being done on two possible standardized ceiling constructions and a standardized wall construction. Both concepts make use of the compressional strength of CLT combined with the tension strength of natural or glue-laminated timber. The basic module of the standardized components is interlocking CLT panels with loose tenons made of beech veneer plywood. The difference between ceiling and wall elements is the load transfer. Both ceiling constructions as components of high bending load use the CLT panels as pressure zone and glulam beams or board layers as tensile zone.
