WeepVent™ | Keep Weep Holes Open, Insects and Debris Out

WeepVent for masonry cavity walls helps ensure that moisture can migrate out and air can circulate into the cavity, and that insects can’t enter the cavity through the weep holes.  The product’s compressibility means it can completely fill the weep holes, and “prickly adhesion” holds the WeepVent in place without fasteners or adhesives.
