Description

Fortiflash 40 mil self-adhered flashing tape roll

Fortiflash is a self-adhered waterproof flashing membrane designed to help protect openings and penetrations from water intrusion. Its rubberized-asphalt core self-seals around nails and fasteners, while strong adhesion helps keep the membrane in place for window, door, and wall applications.


Key Features:

  • Self-Adhered Installation: Peel-and-stick application with strong adhesion to help keep flashing positioned without mechanical fasteners.
  • Watertight Nail Seal: Rubberized-asphalt core self-seals around nails and fasteners for lasting water resistance.
  • Durable Reinforced Construction: Engineered to resist delamination and tearing in demanding conditions.
  • Code/Standard Compliance: AAMA 711 compliant for window/door flashing applications.
  • Sized for Detailing: 6 in. x 75 ft. roll is ideal for window/door perimeters and wall penetrations.

"Ordered the limited edition and it does exactly what it's supposed to do. Used it at the desk for video calls all month. Button is a bit stiff at first but loosens up with use. Five stars from me."
