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.
Guidelines and resources to assist with compliance for the BCA sound insulation provisions. Information covers the acceptable levels of sound insulation within design, construction, development, certification and approval of timber-framed construction.
By following some basic acoustic design elements, better sound control can be provided for timber framed construction.
By understanding sound transmission, adequate resistance to the passage of sound can be incorporated into building design.
Free design guide on acoustic requirements and guidelines for designing and building with timber.
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 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 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 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).
AS 1684 Part 4 provides simpler design procedures than those contained in Part 2, for N1/N2 wind classifications only. The scope of Part 4, including house geometry and range of stress grades is also more limited.
