Thermal Break
1 Definitions

Thermal Break

• An element of low thermal conductivity placed in an assembly to reduce or prevent the flow of thermal energy between conductive materials.
• A typical example would be that found in a metal window frame to reduce the conduction of heat from the outside to the inside.
• (GreenSpec AEP ’09)

Thermal Break

• Unwanted heat loss or gain occurs due to conduction through a thermal bridge through thermal insulation and through thermaly conductive materials.
• To reduce or prevent this heat loss or gain a thermal break is included in the construction in place of the thermal bridge.
• Thermal breaks need to have greater thermal resistance or lower thermal conductivity than the thermal bridge and ideally by a considerable margin.
• Thermal breaks are used in window sections, external doors, curtain walling, at floor edges and between floors and cantilevered balconies.
• An extensive set of components are needed for external solid wall insulation with rendered finish to address the thermal bridges created around windows, doors, externally mounted services, gutters, pipes and many other abutments.
• See: Extrusion
• (NGS BRM ‘09 – GBE BRM ‘16)

Thermal Break

• Element of low thermal conductivity, space or vacuum placed in an assembly to reduce or prevent the flow of thermal energy between conductive materials.
