Flipping of panels may be hazardous in regards to shear loading of lifting screws. Requires more individual lifts and time in regards to jointing. Wall height not exceeding 2,95 m ≤2,95m Transport limitations: Height: 3,0 m Width: 2,40 m Length: 13,5 m Panels can be transported vertically and requires no flipping during assembly. Using wall panel of ex. 2,95 m will result in reduced waste and work-flows in the factory and on site. CLT standard size table 1.1 Structural system

Analysis of sound performance requirements On the basis of experiences gained in solid timber project such as Limnologen, Sweden 2009, the acoustic climate showed to be challenged by sound waves under the normal frames of frequency. Provided the issues with light-buildings and transfer of sound, the building must fulfil sound class B which is added the spectral correlation Rw C 50-3150.
