Benjamin Obdyke’s HydroGap SA self-adhered drainable weather-resistive barrier has a continuous acrylic adhesive that seals around fasteners and penetrations, while 1mm spacers create a drainage path for bulk water. Benjamin Obdyke says the adhesive also contributes to tear resistance and diminishes the chance for ballooning and blow-off. The new WRB has a perm rating of 12, is UV-resistant for 120 days, and comes in 80-foot rolls. Contact local distributor for pricing.
