Cell vents are installed in the bottom vertical mortar joint of a brick veneer wall. It consists of many small adjacent passageways, which allows moisture to vent from the cavity to the exterior of the building while restricting ingress of insects. The cellular composition provides easy drainage for moisture along the full height of the head joint. Cell vents are UV resistant and tested in conformance to ASTM D2240, D790B, D638 and D 1238B.
