FortiFlash Butyl provides a strong, tear-resistant, self-sealing barrier to protect windows, doors, and through-wall penetrations from moisture intrusion. It can also be used for non-roofing horizontal applications such as pot shelves, parapets, still pans, and recessed windows. Made with advanced adhesive, FortiFlash Butyl can be installed in temperatures as low as 25° F and can withstand extreme temperatures up to 250° F. It is compatible with most sealants and the split-back release liner allows for easy integration with weather-resistive barriers.

When used as part of the Henry^® 1-2-3 Moisture Control System™, FortiFlash Butyl backed by an industry-leading 15-year warranty. Repairs are covered for both materials and labor with a single point of contact.
