Ancon Thermal Breaks Minimise heat loss while maintaining structural integrity Thermal bridging occurs where the insulation layer is penetrated by a material with a relatively high thermal conductivity. Although heat loss through a stainless steel support bracket may not be significant, it should be considered as part of the overall thermal performance of the building. Brick support systems from Ancon can now be supplied with Thermal Breaks to minimise heat loss through cold bridging, and improve the energy efficiency of your building project. Ancon Thermal Breaks work by inserting a material with a lower thermal conductivity between the brackets and the frame. Shaped like a standard Ancon key-hole shim, these Thermal Breaks are designed to locate quickly and easily. They are manufactured from a durable fibre-reinforced thermoset plastic, which has a thermal conductivity of just 0.3W/mK*. Ancon Thermal Breaks Low thermal conductivity, 0.3W/mK High compressive strength Proven through thermal modelling to reduce heat loss Typically enables details to comply with BRE IP1/06 floor junction (0.07W/mK) Standard, available from stock Water- and flame-resistant Quick and easy to install In the document SCI P380 ‘Avoidance of Thermal Bridging in Steel Construction’, the Steel Construction Institute suggests “for bracket spacings less than 600mm, thermal spacers between the bracket and the edge beam may need to be considered”. Ancon Thermal Break, ref. BK03 * For comparative purposes, stainless steel and carbon/galvanised steel have a thermal conductivity of 17W/mK and 50W/mK respectively.

Ancon Thermal Breaks Maximum Shimming Allowance The maximum thickness of shims should not exceed the outside diameter of the fixing or 16mm, whichever is less. The 3mm thickness of an Ancon Thermal Break should be taken into account when calculating the maximum shimming allowance for a system. Installation Guidance Ancon Thermal Breaks can be used singularly or as part of a shim pack. When used in conjunction with stainless steel shims, the Thermal Break should be located against the structure. Care should be taken not to exceed the maximum shimming allowance.
