HydroGap® Drainable Housewrap is among the best-performing moisture management products on the market. This product combines the water-resistive layer of a traditional housewrap with a proper gap to facilitate water drainage from behind the exterior siding. Using this product inspires construction professionals to Build Better™ by effectively eliminating excess moisture, preventing long-term damage caused by mold and rot.  

The standout feature of this product is the patent-pending one-millimeter spacer that is strategically spread across the exterior surface of the weather-resistive barrier. The spacer function allows at least 100X more bulk water to drain from a wall compared to standard housewraps. It’s not just about how much gets out; it’s how fast it does. The technology behind HydroGap immediately starts draining water as soon as it enters the building envelope.
