AS 4440 - Installation of nailplated timber roof trusses

An overview of Australian Standard AS 4440 which provides designers, builders, carpenters and truss manufacturers with the requirements and specifications for the installation, bracing and connection of nailplated timber trusses.
Thursday, 13th January 2022

Overview of the Standard

The purpose of AS 4440 is to prescribe the requirements and specifications for the installation, bracing and connection of nail plated timber trusses.

This Australian Standard applies to residential structures (Classes 1, 2, 3 and 10) and light commercial but may include other classes of buildings if the design, loadings and other parameters are applicable.

What does it include?

AS 4440 is broken into 6 sections consisting of:

  • Section 1 deals with what the standard covers and the terms and definitions in the standard.
  • Section 2 deals with the supporting structures of trusses such as the walls.
  • Section 3 deals with the truss installation. 
  • Section 4 deals with the permanent bracing requirements for roof trusses.
  • Section 5 deals with the minimum requirements for truss-to-truss connections.
  • Section 6 deals with the two general types of truss-overhangs i.e. raking-eaves overhangs and boxed-eaves overhangs.

This standard also contains 7 informative appendices consisting of:

  • Appendix A provides detail on any documentation at approval stage and on delivery.
  • Appendix B gives some recommended practices for the installation of nailplated timber trusses.
  • Appendix C provides temporary bracing details recommended for gable, hip and Dutch-hip end roof trusses.
  • Appendix D gives detailed recommendations for the fixing of intermediate ceiling joists and hangers as part of the roof truss system.
  • Appendix E provides recommendations for the transport, storage, lifting and handling of timber nailplated trusses.
  • Appendix F mentions a typical example of a steel brace.
  • Appendix G provides typical fixing details for girder brackets (truss boots).

Is the Standard referenced in NCC or other legislation?

Yes, this standard is a secondary reference through the timber framing standard AS 1684.

Who is the Standard for?

This standard’s primary users are truss manufacturers, builders, carpenters and building certifiers and surveyors.
