<p>The covering consists of a corrugated supporting panel (3) with ribs (6), an insulating layer (9) and a waterproof covering material. The insulating layer is connected to the supporting panel by fixings (13). The fixings are joined to insert strips (14) adapted to the shape and dimensions of the ribs (6) and joined to them by fixings (18). Alternatively, the insert strips can be of different shapes, either with lengthwise folds or tongues to attach them to the ribs. They can have up-turned lower edges to join them to the fixings between the supporting panel and roof girders (2) below them.</p> |
