Substructure
The mounting of the basic substructure must be carried out according to project-specific, static calculation. The general approval Z-33.1-1175 of the construction supervisory authority serves as basis.
The profiles of the basic substructure have to be mounted perpendicularly and in a flush way.
The system rails have to be precisely aligned horizontally and fastened at the provided holes by means of screws or rivets.
The distance of the rails in horizontal direction must correspond to the longitudinal grid of the panels.
The length of the vertical profiles must be divisible by the height of the panel format and should not exceed the height of a storey of the building.
For further information, see the standard technical details of the system K20, which we will make available to you on request.
