In this video, Matt Risinger delves into the three non-negotiable principles of a well-built home that ensure longevity, safety, and comfort. He starts by emphasizing water management, the cornerstone of durability, detailing the essential control layers behind your home’s exterior. From proper sheathing materials to best practices for sealing windows, doors, and penetrations, Matt outlines how to prevent water intrusion and avoid costly issues like mold and rot. Next, he tackles HVAC placement, explaining why all equipment and ductwork must remain within the conditioned envelope of the house. By avoiding mistakes like running ducts through unconditioned attics or placing furnaces in garages, you can maintain efficiency, improve air quality, and ensure a healthier living environment. Finally, he highlights the importance of air sealing and blower door testing, advocating for tight construction to control airflow and moisture. Matt offers achievable air-tightness goals for Southern and Northern builders, while debunking the myth that houses can be “too tight.” Throughout the video, Matt provides actionable tips, material recommendations, and references to related educational content. Builders, remodelers, and homeowners alike will gain valuable insights to elevate their projects and meet modern standards for high-performance homes.
