Improved jamb flashing with acute angle at the free edge

摘要

A jamb flashing 10 includes a first plate 11, a flange 12 and a second plate 13. The first and second plates 11, 13 are co-planar, and the plane of the flange 12 is substantially perpendicular to the plane of the plates 11, 13. The free edge 14 of the first plate 11 is turned up to lie at an acute angle X to the plane of the plate 11. The free edge 15 of the plate 13 is upturned. The free edge 16 of the flange 12 is formed as a rounded bead.
