FortiFlash® Butyl

FortiFlash Butyl delivers in the most demanding environments, providing a strong self-sealing barrier to protect windows, doors and through-wall penetrations – as well as nonroofing conditions such as recessed windows, sill pans, pot shelves and parapets. The product’s chemical compatibility with most standard sealants – as well as EPDM and flexible vinyl, makes it the ideal choice on the jobsite.

FortiFlash Butyl’s proprietary compound delivers rock solid adhesion at temperatures well below those where other self-adhesive flashing products just won’t stick — while maintaining its protective properties at service temperatures up to 250° F. An engineered polypropylene facer, the product can be easily worked around protrusions and into tight corners without delaminating or tearing. And the split release sheet makes integration with weather-resistive barriers a snap.

Available in 20 and 30 mil versions.

Part of the Henry® 1-2-3 moisture control system, FortiFlash® Butyl is designed to withstand the rigors of the jobsite and the elements, and is backed by an industry-leading 15-year warranty.
