During an inspection, what is the significance of checking for insulation in the attic?

Checking for insulation in the attic is significant primarily because it helps maintain energy efficiency and prevents heat loss. Proper insulation in the attic is crucial for regulating a home’s internal temperature. It acts as a barrier that slows the transfer of heat between the conditioned interior of the home and the outside environment.

When attics are properly insulated, they can effectively retain heat during the winter months, reducing the need for excessive heating and leading to lower energy bills. Conversely, in the summer, good insulation helps keep the cool air inside, preventing it from escaping and reducing the work that air conditioning systems must do. This not only contributes to lower energy costs but also enhances the overall comfort of a home.

While other aspects are important — such as ensuring safe temperatures, proper ventilation, and even pest control — they are not the primary role of insulation itself. The primary purpose is focused on the energy efficiency and thermal performance of the home.
