Avoidance of Thermal Bridging in Steel Construction

January 1, 2011 by NSC2 in Publications, Technical
Energy efficiency is becoming an increasingly important parameter in the design of buildings. The thermal insulation provided by the building envelope is key to energy efficiency but thermal bridges, weak spots in the insulation, lead to local heat losses that reduce the efficiency of a building.

This technical guidance illustrates how thermal bridging occurs in a number of design situations. It describes the methodologies for calculating energy performance in accordance with regulatory requirements and the control of condensation.  It describes the results of thermal modelling analyses of typical interface details such as beams penetrating the building envelope, balcony attachments and brickwork supports all used in steel construction. It also provides whole building modelling results with SAP ratings and target emissions rates.

The details described in the publication have not been designed to optimise thermal performance and in practice further thermal modelling analyses could be carried out to quantify the improvement in thermal performance that modifications to the details could deliver. However, the information can be used as general guidance on how to minimise thermal bridging in steel construction.
