Henry FortiFlash Waterproof Flashing Membrane (25 mil) 6 in. x 75 in.

FortiFlash is a self-adhesive waterproof flashing membrane for windows that provides lasting protection against water intrusion in the most demanding environmental conditions. It can also be used for flashing non-roofing horizontal conditions such as pot shelves, parapets, sill pans and recessed windows. The strong adhesion makes it effective in sealing around common through-wall penetrations such as hose bibs, vents, electrical boxes and exterior lights.

• Superior waterproofing – seals out water for lasting protection
• Durable and reliable – self-seals around nails and resists tears
• Easy, self-adhesive install – no fasteners needed
