Henry HE018FFB929 FortiFlash Butyl Waterproof Membrane 20mil 4"x75'

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 job site.

FortiFlash Butyls proprietary compound delivers rock-solid adhesion at temperatures well below those where other self-adhesive flashing products just won't stick -  while maintaining their 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.
