Building Science 101: Understanding Vapor Control

Matt Risinger explores one of the most misunderstood topics in building science: vapor control. Sponsored by Huber Engineered Woods, the episode explains why managing moisture is less about stopping vapor and more about preventing condensation inside building assemblies. Using a replay from the Building Science 101 series with Steve Baczek, Matt breaks down how vapor moves through walls, roofs, and floors, why climate and material selection matter, and how builders can make smarter decisions about vapor retarders and air barriers. The conversation focuses on practical building science principles that improve durability, moisture management, and long-term building performance rather than relying on outdated rules of thumb.
