In this episode of The Build Show, Travis dives into best practices for taping exterior openings for air control — and why he’s doing things a little differently this time. He walks through how mid-wall window and door installations change the approach, comparing ZIP System flashing tapes with SIGA’s Fentrim products.

Travis explains when and why to mix systems, the benefits of split-back tapes for cleaner application, and the importance of proper surface prep for long-term performance. Along the way, he shares insights learned from builders like Jake Bruton and Steve Baczek, shows real-world details (including a few “not perfect” moments), and demonstrates how to back up your air-sealing system with fluid-applied products for a true belt-and-suspenders approach.

If you’re serious about airtightness, mid-wall installs, or just want a deeper look at professional window and door taping, this episode is packed with practical takeaways. To see more of Travis episodes check the links below.
