DictionarySeethermal barrierThermal break
thermal break[¦thər·məl ¦brāk] (building construction) A component that is a poor conductor of heat and is placed in an assembly containing highly conducting materials in order to reduce or prevent the flow of heat. Also known as thermal barrier. Thermal breakMethod of increasing the thermal performance of a material or assembly by reducing conductive heat loss. By inserting a less thermally conductive material in a material or assembly that bridges conditioned and unconditioned space, the conductive path is reduced or broken. An example is the thermal break featured in aluminum-framed windows.thermal break, thermal barrierAn element of low heat conductivity placed in an assembly to reduce or prevent the flow of heat between highly conductive materials; used in some metal window or curtain wall designs intended for installation in cold climates. |
