StormFlash™ Self-Adhering Flashing
Protect Your Home From Wind-Driven Rain And Damaging Ice Dams With A Waterproof
Leak Barrier
Self-Adhering Flashing - Air & Moisture Barrier Will:
- Eliminate leaks caused by wind-driven rain, ice, and snow build-up
- Stop cold drafts
- Stop wasting energy by sealing around window and door openings, rooftop penetrations,
and roof deck joints
Some leaks aren’t detected until serious damage occurs. Protecting the vulnerable
areas of your home with the installation of window and door flashing will help avoid
the costly effects of dry rot, decay, and mildew.
StormFlash™ self-adhering flashing has earned the prestigious Good Housekeeping
Seal, which means that Good Housekeeping stands behind this product. (Refer to Good
Housekeeping Magazine for its consumer protection policy.)
