What material is commonly used as a thermal barrier?

Wood is commonly used as a thermal barrier due to its natural insulating properties. It has a low thermal conductivity, which means it resists the transfer of heat, helping to maintain temperature differences between environments. This property makes wood an effective choice in construction and insulation applications, where minimizing heat transfer is important for energy efficiency and maintaining comfortable indoor climates.

While other materials may have insulating characteristics, wood stands out for its combination of thermal insulation, structural integrity, and sustainability in many applications. For instance, in building construction, wood framing is frequently employed to help create energy-efficient structures by reducing heat loss in colder climates.
