A thermal break, is an insulating material that is strategically placed between highly conductive components within the building envelope, acting as a thermal barrier to interrupt the flow of thermal energy. Materials such as aluminum, steel, and concrete are examples of conductive structural components that can be efficiently thermally broken. By reducing the transfer of heat from one side of the to the other, the thermal break acting as a thermal barrier can significantly enhance the energy efficiency of a glass wall, window, or door design. Therefore, cutting down on your energy costs.
