Benjamin Obdyke introduced HydroGap™ Drainable Housewrap, it combines a water-resistant barrier and drainage system into one application. The housewrap comprises a tri-laminate substrate, with the moisture barrier protected between two non-woven layers. This composition creates a product with superior strength and water hold out. The unique design also allows for the housewrap to be installed in any direction while maintaining its positive drainage capability. HydroGap drains at 93 percent, meeting ASTM E2273, the standard test method for determining drainage efficiency of wall assemblies. It also exceeds AC38 for water-resistive barriers, including the new drainage provision. For more information, visit www.benjaminobdyke.com.
