Noble Co. has been awarded U.S. Patent No. 7.632.401 for its NobleFlex® Drain Flashing. It facilitates the use of a standard clamping ring drain with NobleSeal sheet membranes (and other ANSI A118.10 waterproofing membranes) and is an alternative to integrated bonding flange drains. The Flashing provides a “smooth transition between the TS and a clamping ring drain,” the company says.
