Standards & Codes

This section contains information on timber design and construction compliance related to fire, acoustics, building classes, environmental impact, thermal performance and quality assurance. Additionally, it specifically covers MRTFC (Multi-Residential Timber Framed Construction) and AS 1684, a four-part Australian Standard covering compliance for timber framing.


  • Environmental timber housing

    Environmentally friendly housing design principles using traditional timber construction aid informed decision making by designers, architects, builders, developers, home buyers and building authorities.

  • Machine proof-grading

    Proof-grading begins with the preliminary sorting of ungraded timber being produced by the mill. Machine proof-grading then will further test every piece of sorted timber by the application of a predetermined bending load, known as the proof load.

  • Environmental benefits of building with timber

    Construction design can contribute greatly to maximising comfort and to minimising non-renewable energy consumption. Timber frame buildings are now being designed to meet low energy construction standards, as timber has a high standard of thermal comfort while consuming minimal non-renewable energy.

  • Environmental considerations for timber design - Overview

    A look at some of the environmental requirements, guidelines and considerations for designing and building with timber.

  • Fire Hazard Properties

    The Building Code of Australia (BCA) regulates materials that are used in construction of Class 2 to 9 buildings (not single family homes). These are stipulated by "Specification C1.10".

  • AS 1684 User Guide no. 10 - Distribution of racking forces

    AS 1684 User Guide 10 - Distribution of racking forces via diaphragms and bracing walls

  • AS 1684 - Code Compliance Overview

    AS 1684 Residential Timber Framed Construction is a four-part Australian Standard covering design criteria, building practices, tie-downs, bracing and span tables for timber framing members. By complying with this Standard, users are Deemed to Satisfy the requirements of the Building Code of Australia.

  • AS 1684 Part 1 - Design criteria

    AS 1684 Part 1 sets out the basis for calculating timber sizes and forces to be resisted by tie-down and bracing. It provides a standard reference for designers and product manufacturers to produce compatible engineering solutions.

  • AS 1684 Part 2 - Non cyclonic areas

    AS 1684 Part 2 covers design and construction details for non-cyclonic areas. Four wind classifications are covered: N1, N2, N3 and N4 (previously 28, 33, 41 and 50 m/s).

  • AS 1684 Part 3 - Cyclonic areas

    AS 1684 Part 3 is similar to Part 2 except that it covers design and construction details for cyclonic areas. Wind classifications covered are C1, C2 and C3 (previously 41C, 50C and 60C).
