The load-bearing rafter system, floor beams, insulation materials and the main roof material are installed.
The rafter system is the "foundation" of any sloping roof.
The aesthetic appearance, as well as the reliability and durability of the entire structure depend on the installation technique of this system.
A number of requirements must be strictly adhered to when installing the rafter system.
The main of these requirements is the rigidity of each part, light weight of the structure and high quality of the material.
