From The Build Show.
In this episode of That ’70s Remodel, Stephanie takes us inside a pivotal stage of the home transformation, where energy efficiency meets real-world construction challenges. This mid-century house started with outdated insulation, leaky walls, and inadequate HVAC—but Stephanie and the team are on a mission to turn it into a high-performance home. Viewers follow along as they implement Zip System® R Sheathing for a continuous exterior insulation and water-resistant barrier, dramatically improving the building envelope. A mid-construction blower door test reveals dramatic progress, dropping air changes per hour from over 8 to just about 2. Despite mechanical rooms still open and the attic yet to be insulated, the improvements are already clear. Stephanie discusses the importance of adding an ERV system to ensure fresh indoor air in a tightly sealed house, and shares insights on solving unexpected issues during renovation. It’s an inside look at how modern building science revitalizes a ’70s structure for today’s standards. Huge thanks to our series sponsor, Huber. See the link below.
