The purpose of a thermal barrier in roofing is to protect against heat transfer and improve energy efficiency. Thermal barriers are designed to reflect heat away from the building during the hotter months and retain heat indoors during the colder months. This function is crucial for maintaining a consistent internal temperature, which can lead to reduced energy consumption for heating and cooling systems. The effectiveness of a thermal barrier contributes significantly to energy efficiency, thereby lowering utility bills and increasing comfort levels within the building.

While moisture release is essential in roofing systems to prevent issues such as mold and mildew, it is not the primary function of a thermal barrier. Similarly, the durability of the roof is important, but thermal barriers primarily focus on regulating temperature rather than enhancing the physical longevity of roofing materials. Lastly, while aesthetics can be a consideration in roofing design, the primary role of a thermal barrier is more functional, targeting heat management rather than appearance.
