A thermal break is a non-conductive material or element placed between two conductive materials to reduce the transfer of heat. It is used in building and construction to prevent thermal bridging, where heat can flow through a building’s structure and cause energy loss or condensation. Thermal breaks can be made from different materials, including plastics, fiberglass, or rubber, and are typically installed in windows, doors, and curtain wall systems. They improve energy efficiency, reduce condensation, and enhance the overall performance and durability of a building.
