<p>The covering system is used for conducting rain water in a roof construction and employs an under roof of strip material construction which is securely braced and fixed. At the same time, no material must be cut away from the rafters or any underlay fixed between them. The covering system, at least on one side, must be structured with a fixed underlay, at least on one side is also a first strip acting as an underlay profile, an under-roof and a covering profile. A preferred variant involves a second edge strip known as a bracing profile, placed over the under roof and beneath the covering profile. The covering profile or the bracing profile are fitted above the underlay profile and both act to brace and fix the under roof.</p> |
