Abstract:
A deformable roof flashing material for use in connection with skylight windows and the like roof penetrating structures, said roof flashing material comprising 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, wherein at least the intermediate layer/s (4; 5, 6) adjacent to the outer layers is/are made from a non-adhesive resilient material having a flexibility and elasticity such that the intermediate layer/s is/are deformable with the outer layers during mounting, and in that 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.
