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 non-roofing 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, all the while maintaining its protective properties at service temperatures up to 250 °F. Reinforced by a heavy duty multi-layered polyethylene 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.
