Abstract
A deformable sheet material at least partly comprising a sheet metal or metal foil which is corrugated, e.g. by rolling, in continuous waveform in two directions (A, B) substantially orthogonal to each other. The sheet material can comprise aluminum foil with a thickness between 0.005-0.4 mm designed as a ribbon or a strip which prior to the rolling is folded in the longitudinal direction where an intermediate layer, e.g. of aluminum, can be placed between the two material layers.
Claims13
A deformable roof flashing member for use in connection with roof windows and similar roof penetrating building structures, comprising a ribbon or strip, one long side of which is intended for connection with the roof penetrating building structure, said ribbon or strip comprising at least partly a manually deformable metal sheet or foil corrugated in a continuous waveform, characterized in that the ribbon or strip comprises at least two overlying layers of said metal sheet or foil, each of which is corrugated in a continuous waveform in two directions substantially orthogonal to each other.
