Thermal break | Garaga

Thermal break


A thermal break is an element of low thermal conductivity placed in an assembly to reduce or prevent the flow of thermal energy between conductive materials. InterlockTM triple-contact interlocking joints create a thermal break to completely seal gaps, block cold air between door sections, and prevent cold or heat transfer. Wood end blocks are also the most effective thermal break of all.
