What is the primary purpose of using insulation in buildings?

The primary purpose of using insulation in buildings is to improve energy efficiency. Insulation works by reducing the rate of heat transfer between the interior and exterior of a building, which helps maintain a consistent indoor temperature regardless of outside conditions. This temperature stability leads to reduced energy consumption for heating and cooling systems, ultimately lowering energy bills and contributing to environmental sustainability.

When insulation is properly installed, it contributes significantly to the overall energy performance of a structure, making it a critical component of modern building practices aimed at minimizing energy use and maximizing comfort. The effectiveness of insulation in preventing heat loss in winter and heat gain in summer plays a vital role in enhancing a building's energy efficiency.
