Description

This Standard specifies the procedures for installing bulk thermal insulation in dwellings. The requirements were compiled from a wide range of procedures used in Australia and considered as consistent with good building practice in the installation of bulk thermal insulation.

The Committee has recognized the risk of certain electrical cables and equipment overheating when operating for extended periods when partially or completely surrounded by thermal insulation. To minimize this possibility a pre-installation inspection has been
called for in order to identify whether this potential problem may occur where the thermal insulation is to be placed. The procedure to be adopted as a result of the inspection is set out in this Standard.

The Standard does not attempt to specify requirements for every method of installation of insulation. Rather, it provides general requirements, together with a number of common methods.

The various sub-structures that may be insulated with bulk insulation are dealt with in Section 5 with cross-references where necessary.

It is recommended that users of this Standard read the document as a whole rather than only referring to information on the specific building sub-structure to be insulated.

Installation of bulk thermal insulation, using the requirements and methods given in this Standard, will lead to reduction of heat gain in summer and of heat loss in winter. Bulk insulation and membranes work together to control heat, air and moisture, therefore the properties of membranes should always be considered. This Standard may also be read in conjunction with AS/NZS 4200.2, Pliable building membranes and underlays, Part 2: Installation requirements.

Originated as AS 3999-1992.

Scope

The Standard sets out requirements on installing insulation in both new dwellings during construction and the retrofitting of insulation in existing buildings.

This Standard is intended for residential-type construction; however, the methods may be appropriate to other forms of construction.

This Standard includes requirements for electrical safety and guidance on Work Health and Safety.

This Standard is not intended to apply to the insulation of building services and equipment or materials with structural and/or external cladding or internal lining purposes.

This Standard does not deal with insulation that is foamed in situ nor the installation of pliable building membranes except when forming part of a bulk insulation product.

Insulation installed for the sole purpose of reverberation control is excluded from this Standard.

For the purposes of this Standard, bulk insulation also includes products which create multiple airspaces with a total installed product thickness greater than 20 mm.
