Brick Veneer Ties

The 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.
