What is the primary purpose of using a thermal barrier in construction?

The primary purpose of using a thermal barrier in construction is to provide insulation. Thermal barriers are materials or systems that limit the transfer of heat between two spaces, which is essential for maintaining energy efficiency within buildings. By reducing heat loss in winter and minimizing heat gain in summer, these barriers help regulate indoor temperatures, leading to significant energy savings and increased comfort for occupants. Insulation also plays a critical role in meeting building codes and energy efficiency standards.

While other options may have their own advantages, such as aesthetic improvements or noise reduction, they do not capture the primary intent of a thermal barrier, which is fundamentally aimed at controlling heat transfer and enhancing thermal performance in a building's envelope.
