Explore impacts, Performance Requirements and more in the Thermal bridging in residential buildings resource, part of the ABCB’s Understanding the NCC (UtNCC) series.

What is thermal bridging?

Thermal bridging is an unintended path of heat flow between the outside and inside of the building. Thermal bridges can reduce the effectiveness of insulation and can have a significant effect on the energy efficiency of buildings. Requirements to reduce the impact of thermal bridging are contained in the energy efficiency Deemed to Satisfy (DTS) provisions in NCC Volumes One and Two. 

Help is at hand with our resource

In our Thermal bridging in residential buildings resource, you’ll find information about Performance Requirements and DTS solutions regarding thermal bridging in Class 1 buildings (houses) and Class 2 buildings (apartments and common areas). 

This Understanding the NCC resource includes information on: 

  • impacts of thermal bridging
  • DTS Provisions for thermal bridging in houses, apartments, and common areas of apartment buildings
  • fixing thermal bridging.

This resource complements the UtNCC Thermal bridging in commercial buildings resource, which contains links to case studies showing the impact of thermal bridging in various types of commercial buildings using different materials. 

The information in these resources is useful for architects, building designers, façade engineers, builders, and environmentally sustainable design (ESD) consultants.
