1 WORK INCLUDED

(1) Metal Cap Flashing

Fabricate and install in keeping with the Standards in Part 13 METAL FLASHINGS. Base membrane must extend across the top of the parapet (to waterproof the structure and separate the metal from moisture-susceptible substrates) and extend down the outside face of the parapet at least 50 mm (2”). Edges must be hemmed (1a), although a kicked-out drip edge is optional (see 13.3.2 (1) Fabrication).

(2) Fasteners

Select for compatibility with metal flashing, membrane and substrate (see 13.2.3 Fasteners).

(3) Clips

Install cap flashings using a continuous or discontinuous metal ‘wind’ clip affixed to the outside face of the parapet, or to the top of the parapet (see Alternate illustration). Fasten the clip following the standards in both 13.3.3 Securement and 13.3.5 Cap, Counter and Base Flashings.

(4) Seam

Must be either a Standing Seam (illustrated) or an S-lock (single or double – see inset illustrations). The use of acceptable seams allows for multi-directional expansion and contraction of sheet metal.
