E. Mortar net: high-density polypropylene (HDPE) or nylon strands woven into a 90% open mesh; 1" thick; designed to trap and suspend mortar in the cavity to keep weeps open.
Brick Veneer TiesThe key requirement for brick-ties used with an exterior wall insulation application is the length of the leg.
The one shown in the illustration above has a leg length of 4 inches. This is usually sufficient to allow for the thickness of the foam and the air space between the foam and the brick veneer.
FOAM-TECH has had success using the Dur-O-Wall D/A 213 product with the 4" leg. | |||||
