It is vital to find smart use for cut-offs from the CLT-production, which is typically 5-10% ofthe volume, due to e.g. window and door openings. One application is to make CLT-boards anduse them in timber frame walls as horizontal rails. The cross layers have fibres in the loadingdirection which enhance the load-bearing capacity. This pilot study indicates that the short termstrength and stiffness of a rail made of 5 ply CLT is 4 times higher compared to that of structuraltimber. Long-term tests showed that CLT-rails (45x95 mm) hardly deformed at all with time,while rails from structural timber deformed substantially, after 6 months of loading with 20kN
