The Build Show Podcast

Matt Risinger, Founder of The Build Show, sits down with architect Steve Baczek and Author/Builder Mark Wille for a preview of the Build Science 501 series, covering building science concepts for builders, architects, and homeowners. They explain double wall construction and its role in thermal bridging, exterior insulation, and framing practicality in cold climates. The conversation moves to vapor control layers, why water and air control come before vapor concerns, and how that approach reduces mold risk. They also discuss air tightness, blower door testing, and why more insulation alone doesn’t make a better wall, using coolers and windows as comparisons, along with common mistakes in northern homes.

In part two of their insulation series on the Build Show podcast, Matt Risinger, Founder, The Build Show and Travis Brungardt dig into board insulation, with a focus on basements and foundations. They compare rigid foam, polyiso, and mineral wool boards, covering water management, vapor-open assemblies, and thermal continuity. The conversation weighs interior against exterior placement below grade, including pest pressure, inspection access, and drainage. They also cover insulating slabs, offsetting joints in multiple layers, and how compressibility and labor affect installation. Durability and moisture control come up throughout, tied to the BUILD HD standard.

In this episode of the Build Show Podcast, Matt Risinger and special guest Jake Bruton discuss lessons they’ve learned from building homes for their own families and how those experiences have influenced their approach to clients. They talk about communicating plans more clearly, using 3D models and physical mockups to help clients understand spaces, and setting realistic expectations around construction schedules. The conversation also explores HVAC design, comfort, zoning, ventilation rates, and the importance of monitoring indoor air quality in high-performance homes. Matt and Jake share experiences with tight building envelopes, air sealing, pest control, and the realities of completing work themselves.

On this episode of the Build Show Podcast, host Matt Risinger talks with architect Steve Baczek and builder Mark Willie about Joe Lstiburek's well-known list, "Top 10 Dumb Things to Do in the South." The three work through building science missteps common to hot, humid climates — vented attics, duct leakage, vapor barriers in the wrong place, painted brick, and carpet over concrete slabs — explaining why practices that work fine up north can cause moisture problems and mold growth in Texas. Risinger draws on his own remodeling experience, describing how negative air pressure and impermeable wall coverings trap humidity inside southern homes.
