INSULATION REQUIREMENTS FOR LANDLORDS

PinkFit® team can help assess your property to determine if it meets the new insulation standards under HHS. Book your assessment here.
Installing new insulation- what are the insulation levels changing to ‘R’ stands for resistance- how well insulation resists heat flow. A rental property must have ceiling and underfloor insulation that meets R-value requirements except where an exemption applies. R-value requirements are different depending on which climate zone the rental property is located in.
Your PinkFit® insulation installer can discuss the requirements depending on your location and building type.
What has changed – increased insulation requirements for existing insulation in ceilings and underfloor The HHS increases the minimum requirements for existing insulation. This means that some homes that did not require new insulation under the 2016 standards may now require a ceiling insulation upgrade or new underfloor insulation.
Existing ceiling insulation must be at least 120mm thick in all areas, except for where safety clearances are required. It needs to be in reasonable condition. If a home has less than 120mm of ceiling insulation, then this must be topped up to meet the minimum R-value requirements in the table above.
Existing insulation should have minimum R-value of 1.3 and must be in reasonable condition. R-value can be determined by using existing records or through assessment by an insulation professional. Book assessment here.
Domestic living spaces with suspended floors must have underfloor insulation
Foil needs to be replaced with new underfloor insulation (not foil) where foil is not in reasonable condition or it does not meet the criteria for exemption (the home owner needs to provide a copy of a compliance document for exemption).

Mandatory ground moisture barrier for enclosed subfloor cavity
If the subfloor space is enclosed and accessible, it is mandatory to install a ground moisture barrier under the Healthy Homes Standards for moisture ingress and drainage . The other requirements are efficient drainage for removal of surface/ground water and gutters, downpipes and drains for removal of roof water.
The PinkFit® team can help you by quoting for the install of a ground moisture barrier.
