Flashing Tips To Avoid Window Leak Paths

Flashing Tips To Avoid Window Leak Paths

Even if you've done it hundreds of times, flashing tricky curves and corners in order to achieve the best watertight and energy-efficient seal can be a challenge.

Huber Engineered Woods, has an advanced line of flashing solutions that include a variety of tapes and a liquid flashing material.

ZIP System® Sheathing and Tape are a sheathing innovation that replaces the need for house wrap with a built-in water-resistive barrier.

Below are Ben's best practices for window flashing using ZIP System™ tapes.

One and Done Sill Pan Solution

Applying individual tape segments to corners to ensure a continuously sealed surface can be tedious.

Ben recommends 6- or 10-inch ZIP System™ stretch tape for the job.

All proper application requires to easily flash the entire pan, is a single piece of tape.

Like all ZIP System tapes, ZIP System™ stretch tape is pressure activated.

For best adhesion, roll over the tape with a J-roller for a tight bond.

Proper Shingling

Then flash over the nail flanges with Zip System® straight flashing tape.

Make sure that the jamb flashings overlap the sill flashing at the bottom of the window, to achieve a correct shingling pattern and avoid creating a window leak path.

ZIP System straight tape also comes in 6-inch width that will give the best adhesion surface area and makes it easy to properly cover at least 2-inches above where the window flashing ends.

Make sure this header flashing also extends at least 1-inch horizontally past your jamb flashing on either side.

Again, rolling the tape with a J-roller helps activate the powerful acrylic bond and smooth out any wrinkles where leaks could occur during application.

ZIP System sheathing and tape products provide efficiency and ease of application on the job site.
