That ‘70s Remodel: Episode 3 - Updating Comfort: Interior Insulation
In Episode 3 of That '70s Remodel Stephanie showcases a comprehensive energy efficiency renovation of a 1969 vacation home in Sandy, Utah. The house had severe performance issues, including excessive air leakage (7.2 air changes per hour) and inadequate insulation (only 70% of walls properly insulated). The renovation used a dual insulation approach: 3-3.5 inches of closed cell spray foam inside wall cavities combined with continuous R6 exterior insulation panels. This strategy was designed for an exterior-only remodel and provided excellent air sealing, moisture protection, and thermal performance while potentially strengthening the aging structure. Additional improvements included a complete HVAC system replacement with modern equipment and air recovery ventilation to handle the now-tighter building envelope. The project demonstrates how strategic upgrades can dramatically improve energy efficiency, comfort, and structural integrity in older homes while keeping costs under $200,000, serving as a model for sustainable renovation practices.
