Statement of proposal: Foil insulation PDF Document 425kb


The Ministry of Business, Innovation and Employment is consulting on a proposal to issue a ban that will prevent people retrofitting residential buildings with foil insulation.

The proposed ban follows safety concerns raised by submitters during consultation on the regulations needed to implement changes to the Residential Tenancies Act (RTA) requiring insulation and smoke alarms in rental properties.
The risk with retrofitting this form of insulation occurs when the foil becomes live, for example from accidental stapling into wiring, and has resulted in deaths in New Zealand and Australia.

In conjunction with the ban, the RTA regulations will also not allow foil insulation to be retrofitted in rental properties. MBIE estimate that 180,000 rental properties will need to be retrofitted with insulation by 1 July 2019 in order to comply with the new regulations.

The ban would relate to the installation of foil in existing residential buildings only – not to new builds where electrical wiring has not typically been installed before foil insulation is fitted.
