This is the favoured system for new buildings and for the restoration of old roofs. Individual fabrication allows the system to be adapted to nearly every type of roof.
Aluminium cladding is fixed to roof lathes or roof boards instead of conventional tiling to create a watertight, completely closed substructure. This structure is equipped with joints to which the modules are connected. The joints can be adapted to the respective module types. A watertight conduit is included in the substructure.
