A thermal break or thermal barrier is an element of low thermal conductivity placed in an assembly to reduce or prevent the flow of thermal energy between conductive materials. The opposite of a thermal barrier is a thermal bridge . In architecture and building construction some examples include the following: a thermal break is also a load-bearing thermal insulation system used in reinforced concrete structures to form a thermal break between cantilever structures and internal floor. insulated glazing – the air or gas between the panes stops the conductive thermal energy from passing through the glass. metal window or curtain wall framing – a separator material is used between the inner and outer frames to prevent the temperature transfer through the frame and condensation on the inside frame. concrete work – a single row of concrete masonry units (CMU block) is commonly set between the inner concrete slab and exterior concrete work to prevent the transfer of heat or cold through the slab. garage doors – in some doors that have high R-rating insulation, a vinyl thermal break is used along the edges of each segment instead of rolled steel. metal and wood-framed buildings - an insulation material installed on the roof, walls and floor prevents thermal short circuit creating the heat transfer through the framing material and controls when desired (winter/summer)resulting in energy savings.
