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. Join us as we break down the concept of sealing your home for optimal comfort, energy efficiency, and indoor air quality. We’ll start by discussing the framing process that sets the foundation for air tightness, focusing on roof-to-wall transitions, truss configurations, and sill sealer applications. You’ll see first-hand how we use products like Prosoco’s joint and seam filler to seal critical transitions, ensuring no air (or bugs!) can sneak in. We also walk through our pre-blower door test results, where we achieved an impressive 0.39 ACH, showing just how tight this home is before any drywall is even up. With a “one hole, one thing” mantra from Jake Bruton, we show how to manage penetrations, from HVAC lines to electrical wiring, using fluid-applied products that ensure long-lasting seals. Whether you’re a builder, homeowner, or just a construction enthusiast, this episode will give you key insights into how to achieve a more energy-efficient, healthier, and tighter home. Let’s get into it!
