Guide on code requirements for retrofitting insulation
Published 31 August 2011
The Department of Building & Housing has published a guide on building code requirements for retrofitting insulation in external walls. It’s not a guide to retrofitting - NZ Standard 4246 covers the practical aspects of doing that.
The guide points out that retrofitting wall insulation requires a building consent, unless a council specifically exempts it: “The guide will help building consent authorities to decide whether wall insulation projects should be exempt from a building consent or to approve or decline applications for retrofitting wall insulation.”
