Insulating the walls of an older home is crucial for improving energy efficiency, comfort, and overall home performance. Many older homes were built with little or no wall insulation, which allows heat to escape in the winter and enter in the summer. By adding insulation, you create a thermal barrier that helps maintain a consistent indoor temperature, reducing the need for constant heating or cooling and lowering energy bills. Wall insulation also helps reduce drafts and cold spots, making the home more comfortable year-round. Additionally, it can dampen outside noise and increase the home’s resale value. In some cases, it may even help prevent moisture buildup inside walls, which can protect against mold and structural damage. Overall, insulating walls is a smart upgrade that brings modern efficiency to older construction.
