Welcome back to The Risinger Build! Today, we’re tackling one of the most overlooked yet essential elements of high-performance home building—air tightness.

We break down how sealing a home improves comfort, energy efficiency, and indoor air quality, starting with key framing details like roof-to-wall transitions, truss layouts, and sill sealer applications.

You’ll see how we use products like Prosoco joint and seam filler to seal critical transitions, preventing unwanted air leakage and even pests.

We also review pre-blower door test results, achieving an impressive 0.39 ACH before drywall installation—demonstrating just how tight this build is.

Using a “one hole, one thing” approach from Jake Bruton, we detail how to properly manage penetrations for HVAC, plumbing, and electrical systems using fluid-applied sealing products.

Whether you’re a builder, homeowner, or construction enthusiast, this episode offers valuable insight into creating a tighter, healthier, and more energy-efficient home.

Let’s get into it!
