Moistop E-Z Seal is a high-performance flashing with a self-adhered 3"" backing strip that provides secure installation on the inside of the rough opening. The remaining width of the flashing is mechanically attached for easy integration with the weather-resistive barrier. Moistop E-Z Seal provides a strong, tear-resistant barrier to protect windows, doors, and through-wall penetrations from moisture intrusion. When used as part of the Henry 1-2-3 Moisture Control System™, Moistop E-Z Seal is backed by an industry-leading 15-year warranty. Repairs are covered for both materials and labor with a single point of contact.
