Insulation Standards in Australia

Insulation is an important aspect of any building project, helping to improve energy efficiency, reduce heating and cooling costs, and enhance occupant comfort. However, insulation installation is not simply a matter of filling a cavity with any old material. In Australia, there are strict regulations and compliance requirements that must be followed to ensure that insulation is installed safely, effectively, and in accordance with building codes and Australian standards. In addition, builders and installers must consider a range of factors when selecting insulation materials, including environmental impacts, durability, and cost-effectiveness.


While there are some national standards and regulations for insulation installation in Australia, the specific requirements and governing bodies can vary between different states and territories. However, the overall aim is to ensure that insulation installation is carried out safely and effectively, and that the insulation meets the required standards. Insulation installers in any state or territory should be familiar with the relevant regulations and standards to ensure compliance.

In New South Wales (NSW), the relevant governing body is NSW Fair Trading, which regulates the building industry and provides licences. Insulation installers are not required to hold a specific licence or insulation certificate in NSW for insulation installation work. However, in some cases they must hold a Contractor Licence issued by NSW Fair Trading if they are carrying out building works costing over $5,000.

In addition to this licence, NSW Fair Trading also may require insulation installers to hold a White Card, which is a nationally recognised construction induction training certificate. The White Card demonstrates that the installer has completed the necessary safety training to work on construction sites. However, the white card is only required for workers working on a construction site, allowing retrofit insulation in an existing home to be carried out without an official licence.

NSW Insulation Installation Requirements

NSW also has specific requirements for insulation installation in residential buildings, which are set out in the Residential Tenancies Regulation 2019. These requirements include:

Minimum R-value (NSW): All new and replacement insulation installed in residential rental properties must meet a minimum thermal resistance (R-value) of at least R2.5 in the ceiling.

Installation standards (NSW): The insulation must be installed in accordance with the manufacturer’s specifications and the Australian Standard AS 3999:2015 Thermal insulation of dwellings – Bulk insulation – Installation requirements.

Safety (NSW): Installers must take all reasonable steps to ensure that the installation of insulation does not create a health or safety risk to any person, including the installer.

Insulation Certificate (NSW): Installers are encouraged to provide the property owner with a certificate of compliance after completing the installation. The insulation certificate should include information such as the type and R-value of the insulation installed, the date of installation, and the installer’s details.


In the Australian Capital Territory (ACT), the relevant governing body is the Environment, Planning and Sustainable Development Directorate, which regulates building and construction activities. Insulation installation in the ACT is also subject to specific requirements, which are set out in the ACT Building Code. These requirements include:

Minimum R-value (ACT): As discussed in a recent seminar for landlords in Canberra, all new and replacement insulation installed in residential buildings must meet a minimum thermal resistance (R-value) of at least R2.5 in the ceiling. Note that as of 1 April 2023, there will be a new standard requiring ACT rental properties with no insulation or existing ceiling insulation below an R-value of R2.0 to upgrade their insulation to a minimum R-value of R5.0.

Certification (ACT): In compliance with the new minimum insulation standard, ceiling insulation installations must be carried out by a certified and trained installer under the Energy Efficiency Council’s Professional Certifications Program, with at least one certified installer present on-site during installation to ensure safety and efficacy.

Installation Standards (ACT): The insulation must be installed in accordance with the manufacturer’s specifications and the Australian Standard AS 3999:2015 Thermal insulation of dwellings – Bulk insulation – Installation requirements.

Safety (ACT): Installers must take all reasonable steps to ensure that the installation of insulation does not create a health or safety risk to any person, including the installer.

Insulation Certificate (ACT): Under the new regulation, rental property owners are required to provide evidence of insulation compliance to the ACT Government. Evidence can be:

  • a receipt for insulation installation services that includes the R-value of the ceiling insulation
  • an inspection report from a professional insulation installer
  • an Energy Efficiency Rating report from a building assessor
  • if the property was built in 1997 or afterwards, a statutory declaration that there is insulation and it has not been disturbed
  • a statutory declaration that ceiling insulation with an R-value of R2 or more has been installed.

Assessment of Existing Insulation (ACT): If a residential building is undergoing renovation or alteration work, the Building Code requires an assessment of the existing insulation to determine whether it is fit for purpose. If the existing insulation is found to be inadequate, it must be replaced with insulation that meets the Building Code requirements.


The Building Code of Australia (BCA): The BCA is a national code that sets out the minimum requirements for the design and construction of new buildings, as well as alterations and additions to existing buildings. The BCA insulation requirements includes specific requirements for insulation, such as minimum R-values (thermal resistance) for different climate zones in Australia. However the BCA does not specify the type of insulation that must be used, leaving it up to individual builders and installers to select the most appropriate material for the specific project. This might be glasswool insulation from Knauf Earthwool or Bradford Gold, or a polyester insulation.

Australian Standards (AS): There are several Australian Standards related to insulation installation, including AS 3999-1992 Thermal insulation of dwellings – Bulk insulation – Installation requirements, and AS 4876.1-2012 Domestic external timber-framed and light masonry veneer construction – Design.


Currently, the ACT is the only state where certification is required to install insulation. However, it is only mandatory for those installing ceiling insulation under the new Ceiling Insulation Minimum Energy Efficiency Standard in residential rental properties.

The Certified Insulation Installer certification is held by the Energy Efficiency Council (EEC) and certifies that individuals have the knowledge and skills to deliver safe and effective insulation installation.

In order to apply for EEC full certification, an installer must complete the relevant training to present a Statement of Attainment from a registered TAFE or RTO, hold a valid White Card for the state or territory in which he/she wishes to operate, and hold a Certificate of Currency for Public Liability Insurance (coverage for $5 million+). There are also requirements to maintain and upgrade certification if an installer wishes to remain actively engaged in the delivery of insulation installations.


Certificate of Compliance
This is a document that is issued by insulation installers upon completion of work. The certificate confirms that the insulation has been installed in accordance with the relevant standards and regulations. The certificate is typically required by building certifiers and insurers as proof that the work has been carried out to a high standard.

Safety standards
Insulation installation can be hazardous work, so it’s important that installers follow the relevant safety standards. This might include using personal protective equipment such as gloves, safety glasses, and respirators, as well as ensuring that electrical wiring is not disturbed during installation.

Environmental standards
In addition to safety and building standards, insulation installers may need to comply with environmental regulations. For example, some insulation materials may be classified as hazardous waste and require special disposal procedures.

Quality assurance
Insulation installation is an important investment in a property, so it’s important to ensure that the work is carried out to a high standard. Some insulation installers may have quality assurance programs in place to ensure that their work meets the required standards.

Energy efficiency
Now more than ever, people are asking themselves, “why are energy prices rising?” and, “what can I do to reduce energy bills?” Insulation plays a key role in improving the energy efficiency of a building, so it’s important to choose an insulation installer who understands the importance of energy efficiency. This might include providing advice on the best insulation materials for a particular building, as well as ensuring that insulation is installed correctly to maximise its effectiveness. This applies to all insulation installations, including ceilings and underfloors

Finally, it’s important to consider the cost-effectiveness of insulation installation. While insulation can help to reduce energy bills and improve the comfort of a property, it’s important to ensure that the cost of installation is reasonable and that the expected savings are realistic. Insulation installers may be able to provide advice on the most cost-effective insulation options for a particular property.
