1. Stand up to the abuse of the construction process, eliminating your need to replace or repair them.
2. Perform as intended under the harshest environments for many years with little or no maintenance cost.
X Vent Box vents and sleeves also prevent water and sand intrusion. By using our box along with proper construction sealant (like Sika Flex, Dymeric 112) installed in a properly sized rough opening directly on the CMU or PIP surface, water will not enter the building at the box location. We have a monolithic box cavity design that eliminates the seam between the box cavity and the louver. This location, which has and continues to be a direct source of water intrusion and also contributes to mold and mildew, is now completely protected.
