Patent number: 7550187Abstract: An exemplary moisture barrier membrane 10 comprises a waterproof adhesive layer, (14) a carrier support, (12) and a release liner (16) composite having a paper sheet, (20) cutting strings, (22) a polyolefin (24) coating or film for holding the strings against the paper and apart from the waterproof adhesive layer, and a release agent (26) such as silicone or wax over the polyolefin coating or film. This construction allows for relatively thin paper and strings to be used, such that tear resistance is conferred upon the release liner composite as a whole.Type: GrantFiled: January 16, 2004Date of Patent: June 23, 2009Assignee: W.

Patent number: 7201820Abstract: The invention pertains to a novel method for flashing a door, window, ductwork or other rough opening in a building surface. The method involves the use of a tape strip having a continuous, non-perforated, machine-direction-splittable plastic release sheet liner which is selectively removed in controlled portions without the need for cutting strings. Anisotropic tear-resistance properties of the release liner facilitate a careful, controlled, and progressive installation of the tape strip while avoiding unwanted transverse tearing that could block or foul the adhesive.Type: GrantFiled: October 11, 2005Date of Patent: April 10, 2007Assignee: W.
