Insulation and air sealing is essential for high performance homes and buildings. Smith & McClain works with general contractors and homeowners on insulation system design, specifications, and cost estimates for new construction and renovation projects. Our insulation technicians are trained to install dense pack and loose fill cellulose, as well as other thermal and vapor barrier products used to improve the building envelope. These technicians have vast experience with energy retrofits, renovations and new construction projects that result in an improved quality of life and reduced energy consumption for many clients.
