What is the primary purpose of insulation in buildings?

The primary purpose of insulation in buildings is to maintain temperature and improve energy efficiency. Insulation works by slowing the transfer of heat between the interior of a building and the exterior environment. This means that in the winter, insulation helps keep the warmth generated by heating systems inside, while in the summer, it prevents external heat from infiltrating the living spaces. As a result, effective insulation reduces the demand on heating and cooling systems, leading to lower energy consumption and cost savings. Furthermore, proper insulation contributes to a more comfortable indoor environment by helping to regulate temperature and prevent drafts. This not only enhances comfort for occupants but also plays a significant role in lowering energy bills, making it a key component in energy-efficient building design.
