One-Step Tape Solves Window Frame Leaks
 DuPont™ FlexWrap™, a moldable Tyvek® flashing tape for window sills and custom shapes, was recently chosen by Newsday journalist Gary Dymski as one of the 10 new items that could be a hit in the housing industry sometime soon.
E.I. Dupont De Nemours & Co., Inc. is a member of the National Council of the Housing Industry — The Supplier 100 of NAHB.
Dymski notes that the company’s housewrap has already taken off. “Ever since Tyvek was introduced in the early 1990s, every new house and every new addition is wrapped with a protective barrier to reduce air infiltration and the chances for trapped moisture.”
Part of the DuPont Flashing System, which has been designed to provide homes with comprehensive protection from water leaks, FlexWrap is uniquely engineered to address the issues of flashing the vulnerable bottom corners at the window sill where damage is most likely to occur, according to the manufacturer.
FlexWrap is wrapped into the still rough opening before the window is installed, making one step, seamless protection possible.
The product also flashes round-top or custom-shaped windows in one seamless step and eliminates the need to slowly cut and place individual pieces of conventional flashing to an arched window.
Dymski writes that products like FlexWrap flashing tape make more sense to him because they are “materials with more substance than style” that “can save money for both home owners and contractors.”
Tyvek is an elastic material, a polyolefin film and a highly adhesive butyl sealant that provides high-performance protection for construction and a wide range of other applications.
