DZ4246 Energy efficiency – installing bulk thermal insulation in residential buildings

Public comment is from 6 May – 3 June 2016

NZS 4246:2016 Energy efficiency – Installing bulk thermal insulation in residential buildings provides guidance for the correct installation of quality insulation products by installers and consumers to achieve the intended thermal performance in buildings without compromising the durability and safety of insulation or building elements and the health and safety of installers and building occupants.

The 2006 standard has been fully restructured for better readability, updated, and extended to provide guidance on installing insulation in steel-framed constructions and for concrete slabs on ground.

This standard is presented in sections and has been developed with the intention that each section can be read as a stand-alone set of guidance principles, with reference to other sections as required. As such, there is some repetition between the sections to ensure that no details are overlooked.

Reflective pliable membranes continue to be excluded from the scope of this standard due to concerns about electrical safety risks, in situ thermal performance, and durability. There are now better alternative insulation products, making the further use of reflective pliable membranes unnecessary.

Initial public comment was undertaken in late 2014, and this is the second round of public comment, which will be open for a four week period until 3 June.
