Flashing (flash'-ing)

1. Light gauge materials used to close and finish roof transitions, roof openings, window and door installations and external seams for masonry veneers.

Butyl flashing tape is a non-asphaltic, waterproof butyl adhesive backed with a UV stable conformable white polyethylene film backing. It provides a watertight, puncture proof membrane around exterior door and window installations to ensure they don't leak and prevent long-term water damage to your home. Our flashing tapes are available in 1-1/4", 4" and 6" wide.

Our Butyl Flashing Tape is ideal for use as a window and door flashing tape and as a moisture barrier used in joints where stucco or other exterior masonry veneers are used. It also serves well for joint sealing in roof transitions and in exterior construction joints. Product can also be die-cut for use as a top-sealant for mulled door and window joints.

Butyl Flashing Tape works anywhere joints or spaces threaten to let water, vapor or moisture enter your home and cause damage.

The UV stable film can be applied and left exposed for up to 120 days with no UV damage, and requires no special primers to work as specified if applied within the recommended application temperatures of 35°F to 110°F.

Step 1: Cut your rough opening.
Step 2: Install the window (or door).
Step 3: Run a strip of flashing along the bottom fin.
Step 4: Run a strip of flashing down both sides, overlapping the bottom strip.
Step 5: Run a strip of flashing over the top, overlapping the two side strips. Now you're ready for your siding or outside surface treatment.
