Mansard truss structures are suited for both new builds and renovation sites.

Use of mansard trusses in small houses is cost-efficient and provides additional space for living and other practical use. The length of the bottom chord can be a maximum of 11 metres. The building must have one or two loadbearing intermediate walls.

In buildings with a mansard-truss roof structure, the main structural engineer must ensure that together with the truss, the surface structure of the floor complies with the vibration requirements of RIL 120, the Finnish design code for timber structures. In these issues, the design engineer can always contact our technical assistance service.

When placing an order for a mansard truss, we will require the truss diagrams drawn by the structural design engineer, a floor plan and any elevation drawings available.
