FortiFlash® FortiFlash is engineered to deliver lasting protection against water intrusion in the most demanding environmental conditions. It is the premium self-adhesive waterproof flashing membrane for windows. It is also ideally suited for flashing non-roofing horizontal conditions such as pot shelves, parapets, sill pans and recessed windows. Its strong adhesion makes it a perfect choice for sealing around common through-wall penetrations such as hose bibs, vents, electrical boxes and exterior lights. Yet, its price makes FortiFlash the price/performance solution for the most challenging construction requirements. Reinforced by a strong cross-laminated high-density polyethylene film, FortiFlash can be installed around protrusions and into the tightest corners without delaminating or tearing. Its self-sealing rubberized asphalt core stays in place in the most punishing weather conditions. This is a 25 mil product. 75' Roll x 4"   Qty: $18.49

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 won’t just stick — while maintaining its protective properties at temperatures in excess of 225° 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.FortiFlash Butyl’s proprietary compound delivers rock solid adhesion at temperatures well below those where other self-adhesive flashing products won’t just stick — while maintaining its protective properties at temperatures in excess of 225° F.
