why choose steel


NASH represents the interests of steel frame fabricators for housing and low-rise framed construction, their customers and suppliers. Our members include specialist steel frame fabricators, builders as well as suppliers of products and services to the industry.


NASH has recently published a new  Technical Note NTN-006 – NCC 2022 Elemental Energy Efficiency Solutions for Class 1 Buildings.

NTN-006 provides a wealth of information for fabricators, detailers, designers, building surveyors/certifiers and builders working in the steel framed housing industry. It will help to answer questions for those looking for practical, cost-effective energy efficiency solutions.

Energy Efficiency solutions are presented in the Technical Note for a wide range of common construction cases for Class 1 buildings, using the DtS Elemental pathway to comply with the NCC 2022 requirements.

For any enquiries and to provide customer feedback, please contact NASH.

Thermal Breaks – Where Required

With the rollout of NCC 2022 continuing across Australia, including the move to NatHERS 7-star equivalent energy efficiency requirements, it is timely to remind certifiers, designers, builders and products installers of the correct application of thermal breaks in some forms of wall and roof construction.

NASH has recently published a new Technical Note outlining energy efficiency solutions using the Dts Elemental pathway. Technical Note NTN 006 includes the following explanation of thermal break requirements in steel framed construction:

  • The NCC requires that thermal breaks be used in specific situations. A thermal break, of minimum R-values 0.2, is required where lightweight cladding and lining are directly attached to the same member (eg stud, rafter) or the building is unlined. The presence of any secondary member (eg cladding batten or lining batten) made from any material negates the requirement for a thermal break. This applies to both walls and roofs of residential buildings and has been unchanged since BCA 2006.


National Association of Steel-framed Housing (NASH) has been working with the Australian Steel Institute (ASI) to develop a number of industry reference documents in areas that relate to changes in the NCC and/or provide guidance on good practice. For each topic you will find information, presentations and technical “how to” diagrams that relate to the design and installation of steel framing, steel roofing and walling.

Steel framing in bushfires

Report and video on steel framed and clad building subject to real bushfire attack by CSIRO

Rebuilding in bushfire areas with steel

The 2019/2020 summer bushfire season in Australia has seen the loss of human lives and residential properties, along with agricultural and commercial businesses, wildlife and forests. Given that approximately 3000 homes were destroyed by the bushfire, people rebuilding will be seeking better solutions to increase the robustness of their homes in future bushfires. The NASH Standard – Steel Framed Construction in Bushfire Areas provides simple, economical and robust solutions for building steel framed homes in bushfire areas.
