In this video, we take a closer look at healthier insulation options that are rarely used in modern construction. We break down natural insulation materials like sheep wool insulation, hemp insulation, and wood fiber insulation, and explain where each one makes sense in real buildings. These materials can be used in wall cavities, attic spaces, loose-fill applications, and rigid exterior insulation systems, offering benefits beyond simple R-value. Unlike conventional insulation, natural materials such as sheep wool, hemp, and wood fiber help manage moisture, reduce chemical exposure, and support healthier indoor air quality. We also touch on how these options compare to common products like fiberglass and spray foam insulation, and why they’re often overlooked in typical residential construction. This video is for homeowners, builders, and designers who want to understand insulation choices beyond conventional materials and build healthier, more resilient homes.
