What is one benefit of insulating walls and ceilings?

Insulating walls and ceilings primarily serves to reduce energy loss, thereby lowering heating and cooling costs. This benefit arises because insulation acts as a barrier to heat flow, helping to maintain a comfortable indoor temperature regardless of external weather conditions. During winter, insulation prevents heat from escaping the living space, while in summer, it keeps outdoor heat from entering. As a result, homeowners experience reduced energy consumption, which translates to lower utility bills and increased comfort within their homes.

While increasing the resale value can be a secondary benefit of a well-insulated property, it is not the direct function of insulation itself. Additionally, insulation does not negate the need for key structural elements like roofs or windows, which are essential for a building's integrity and functionality.
