Insulating exterior walls is crucial for improving your home’s energy efficiency and comfort in Aurora, CO. Exterior walls are a major source of heat loss in the winter and heat gain in the summer, making proper insulation essential for year-round comfort. Popular insulation materials for exterior walls include fiberglass batt, spray foam, and cellulose. Fiberglass batt insulation is affordable and effective for standard wall cavities but may leave gaps around fixtures or framing. Spray foam insulation, on the other hand, offers superior air sealing and thermal resistance, expanding to fill every crack and gap, making it ideal for irregular wall spaces. Blown-in cellulose provides excellent coverage and is perfect for retrofitting existing walls without disrupting the interior. It is made from recycled materials, making it an eco-friendly choice. Insulating exterior walls helps prevent drafts, reduce energy bills, and improve indoor temperature regulation. Additionally, insulation protects your home from moisture and condensation issues, reducing the risk of mold growth and structural damage. An experienced Aurora insulation contractor can help determine the best insulation type for your exterior walls, ensuring optimal performance and long-term energy savings.
