Mansard truss

Mansard truss roofs suit well both for new buildings and for reconstructions.  

Mansard truss is traditionally used in small houses to give additional space economically for living and other practical use.
The length of the bottom chord can be maximum 11 metres. It should be noted that the building must have 1 to 2 supporting partition walls.

In mansard truss buildings, the main building design engineer must ensure that the floor surface construction together with the truss complies with the RIL120 vibration requirements.

For an offer request you can fill in the required measurement data on our offer request form. When doing your final attic frame truss order we will need the truss diagrams, the base plan and also the exterior drawings if possible, drawn by the structure design engineer (contact particulars at the bottom of base, on the left).
