In Denver, insulation costs can vary significantly based on the type and installation method. For example, attic cellulose insulation (R-60) costs approximately $1.70 per square foot installed, while wall fiberglass (R-23) is around $2.25 per square foot. Rim joist spray foam (3”) can cost about $5.60 per linear foot installed. Total project costs for a typical 1,800 ft² ranch can reach $7,950, including materials, labor, and permits.
Denver's climate, with its extreme temperature fluctuations, demands high-quality insulation. Proper insulation reduces energy bills and enhances comfort. Up to 40% of heat loss in homes occurs through under-insulated areas, making professional insulation a priority.
