| 摘要 |
The invention relates to all types of roofing by reducing its weight, increasing its insulation capacity and its mechanical resistance to impacts, while limiting the damage due to storms and to strong winds, in comparison to conventional materials. The multi-roofing consists of a waterproof material 1 resembling a slate, a tile ... in its shape and colour; held, without clamping, against the shingles 2 with a metal washer 3 housed in a hole 4 having a diameter which is greater than the fixing screw 5 and interlocking elements 6, a seal 7 and a covering 8 will be used to assemble the roofing. The multi-roofing may find particularly advantageous applications in the field of the building industry and of prefabricated construction while complying with style requirements. <IMAGE>
