AS/NZS 4859.1 Materials for the thermal insulation of buildings Part 1: General criteria and technical provisions

1.1 SCOPE

This Standard specifies requirements and methods of test for materials that are added to, or incorporated in, opaque envelopes of buildings and building services, including ductwork and pipework, to provide thermal insulation by moderating the flow of heat through these envelopes and building services.This Standard does not cover materials for the insulation of windows or other glazing.
Although this Standard covers thermal performance of insulation, there may be requirements in the Building Code of Australia, or elsewhere, for the same material to have other properties such as for acoustic isolation or fire properties. Further, in a regulatory situation, a requirement for thermal performance cannot compromise any other required
performance.

Specific requirements for individual materials or insulation types are given in Sections 5 to 9 of this Standard and in the following Standards:

(a) Rigid cellular polyurethane (RC/PUR) …………………………………………….. AS 1366.1.

(b) Rigid cellular polyisocyanurate (RC/PIR)…………………………………………. AS 1366.2.

(c) Rigid cellular polystyrene Moulded (RC/PS-M)…………………………………. AS 1366.3.

(d) Rigid cellular polystyrene Extruded (RC/PS-E) …………………………………. AS 1366.4.

(e) Urea-formaldehyde foam thermal insulation—In situ set foam ………………… AS 4073.

The scope of this Standard does not cover requirements for fire performance.

1.2 APPLICATION

This Standard is applicable to the full range of climatic and environmental conditions that exist under normal  ircumstances. It is intended for use by regulatory and specifying authorities, insulation manufacturers, developers, architects, builders, building engineers,property managers and commercial and residential building owners.
In order to comply with this Standard, a material or assembly that falls within the scope of AS 1366.1, AS 1366.2, AS 1366.3, AS 1366.4 or AS 4073 shall, apart from fireperformance, comply with the requirements of that standard unless overridden by this Standard.

Materials or assemblies that do not fall within the scope of one of the above Standards or Sections 5 to 9 of this Standard, need only comply with Sections 1 to 4 of this Standard.

NOTE: Alternative means for demonstrating compliance with this Standard are given in Appendix A.
