Tile trim flashings

Abstract

Three dimensional flashings suitable for association with buildings where at least part of the flashing is a shape retaining three dimensional form to render its association with an underlying three dimensional substrate of the building easier even should it not initially match the conformation thereof. Such a flashing in such three dimensional region is adhesively associable with the substrate and includes for shape retention purposes below a suitable flexible weather resistant layer (e.g.; EDPM) an underlying conformable three dimensionally conformed material such as aluminium sheeting (optionally in a mesh form).
