ABSTRACT:
Preformed plastic chimney flashing includes a horizontal plate embedded in the mortar between two courses of bricks, and a lip extending downward from the outside edge of the plate. The plate, which extends across the full width of a brick, has holes for adhesion of mortar on either side of the plate. The lip is intended to cover ordinary metal flashing, which inserts between the lip and the brick wall. The lip includes a ridge on the lower inside edge to help seal against weather. The plastic is colored, weatherproof, and flexible. The flashing is preformed into several shapes adapted to cover runs, steps, corners, and cap bricks. No forming is required, only cutting to length for allow for some overlap.
