Fastening system for fastening solar module to roof structure of building, has casing made of thermally insulating material, and screw whose shaft is guided through lower opening formed in casing

摘要

The system (1) has a carrier profile (100) arranged at a roof structure (2) for carrying a solar module, and a fastening element (40) for fastening the carrier profile to the roof structure. The fastening element exhibits a casing (41) made of a thermally insulating material such as plastic. The fastening element has a fastening screw (44) whose shaft is guided through a lower opening (45) formed in the casing. A side wall of the casing limits a cavity (42) that is accessible through an upper opening of the casing. An independent claim is also included for a roof system comprising an insulating layer.
