How does insulation contribute to energy efficiency?

Insulation plays a crucial role in energy efficiency primarily by reducing heat loss or gain in a building. When buildings are insulated effectively, they prevent warm air from escaping during colder months and inhibit hot air from entering during warmer months. This thermal resistance means that the heating and cooling systems do not have to work as hard to maintain a comfortable temperature, leading to reduced energy consumption and lower utility bills.

By limiting the amount of heat that transfers through walls, roofs, and floors, insulation helps to stabilize indoor temperatures and reduces the need for artificial heating and cooling. This not only conserves energy but also enhances the comfort of occupants within the space. Effective insulation can lead to better energy performance ratings for a building and can contribute to sustainability goals.

While it might seem that attracting external heat sources could be beneficial, insulation's primary function is to create a barrier against unwanted heat influx, ensuring that the building remains energy efficient and comfortable throughout the year.
