Drip
Edge: Complement a Flashing Detail for Cavity Wall Construction |

| BASIC
APPLICATION |
|
|
 |
|
Quality brick veneer cavity wall construction requires an
effective moisture control plan. The CT-Drip Edge is used
as durable and aesthetic extension of the cavity wall flashing
system. In lieu of a protruding flashing material, the CT-Drip
Edge is adhered and sealed to the edge of the flashing material
and extended slightly beyond the bricks edge to provide an
escapable means for water to drip away from the brick surface.
A properly installed drip edge will prevent the water and
return beneath the flashing and shelf angle.

INSTALLATION |
|
|
|
|
Place
CT-Drip Edge on steel shelf angle, consider separating dissimilar
materials with non-absorbent membrane (plastic sheet, flashing,
roof felt, etc). secure cavity wall flashing to drip edge with
sealant, mastic, or place peel and stick to the clean stainless
surface. Full drip edge surface contact is preferable (1”
(25mm) minimum). Avoid fish mouth or puckering of the flashing/drip
laminate materials. Lap CT-Drip Edge 4-6” (100-150mm)
and place sealant between lapped sections. Seal all penetrations
about the drip edge. |
