Moistop E-Z Seal®

Innovative peel and stick flashing with non adhesive border for easy integration

Moistop E-Z Seal®

Moistop® E-Z Seal has set the benchmark for self-adhesive flashings. It is an ultra-high performance self-adhesive flashing that helps produce a perfect finished product. With a strong reinforced polymer membrane coated with a 3 inch self-adhesive strip, Moistop E-Z Seal provides a rock-solid barrier against rain-driven water intrusion – while resisting ripping and tearing in the toughest jobsite conditions. Its adhesive strip provides an incredibly strong bond – the strongest in the industry – ensuring solid integration of the windows and doors with plywood, OSB, aluminum, vinyl and weather-resistive barriers. The product is available pre-cut in 4, 6, 9, and 12 inch widths, to address virtually any vertical wall applications.

Part of the Fortifiber® 1-2-3 moisture control system, Moiststop® E-Z Seal is designed to withstand the rigors of the jobsite and the elements, and is backed by an industry-leading 15-year warranty.
