Alternative Flashing Designs

Designers should consider more alternatives for butt designs to provide weatherproof window flashings.

For example: If the opening is "panelised" the vertical jamb flashing can be extended from soffit to the ground for single storey buildings or to a module break in a multi-storey building as shown in drawing 6.4.5.

This alternative provides the opportunity to use the same or a different material at the head and sill areas, and a top hat flashing is used to obtain a module break.
