Episode 46: Update to the 2021 International Residential Code on Under-slab Vapor Barriers

Tune in each month to ICC Pulse Podcast for a direct line to the conversations shaping our built environment. Produced by the non-profit International Code Council, this series goes beyond the technical text of building codes to explore the people, policies, and innovations driving safety forward. You’ll hear unscripted discussions with engineers, researchers, and policymakers who are on the ground, tackling everything from adapting structures for climate resilience to integrating smart city technologies. Rather than dry regulations, the podcast focuses on the practical impact of these standards on communities and the future of construction. It’s a resource for anyone in government, technology, or the non-profit sector who wants to understand the why behind the rules. Each episode aims to connect the dots between current events, emerging tools, and the code development process, offering a genuine insider’s perspective you won’t find elsewhere. By listening, you gain context on how building safety evolves and how it touches every aspect of modern life.
