A DEFORMABLE ROOF FLASHING MATERIAL AND A METHOD FOR THE MANUFACTURE OF A FLASHING RAIL WITH A SKIRT MADE FROM THE ROOF FLASHING MATERIAL

摘要

The roof flashing material is intended for use in connection with skylight windows and the like roof penetrating structures and comprises a sandwich construction with two outer layers (2, 3) of metal foil and at least one intermediate layer (4; 5-7) positioned between the outer layers, said material having at least in one direction a continuous waveform. The intermediate layer(s) (4; 5, 6) adjacent to the outer layers is/are made from a non-adhesive resilient material, and said waveform is formed in such a manner that it maintains the mutual positioning between the outer layers and the adjacent intermediate layer(s) by friction.
