Timbeco delivered a retirement home in Sweden, constructed of a combination of CLT (cross-laminated timber) and prefab timber frame elements.
The greatest difference between designing a CLT building compared to designing a prefab timber frame element building was the need to take into consideration the manufacturing capacity of the CLT manufacturer. The surface finishing options, possible dimensions and number of layers of CLT elements are largely dependent on the CLT manufacturer. Based on this, Timbeco’s designers performed their strength calculations and designed the junctions.
Openings for windows, doors and vent pipes were cut into the CLT wall elements in the factory. Since one side of the CLT wall elements remained visible, the quality of the visible side had to meet high standards even after the CLT boards were packed, transported and mounted. Using CLT elements for the lift shaft can also be highlighted as an interesting solution. Usually, lift shafts are made of concrete to ensure fire resistance. In this project, however, fire resistance was achieved by using CLT boards.
