SR324 The potential for over-cladding: A scoping study (2019)

This report summarises the findings of a scoping study into the potential for over-cladding as a solution for overcoming the stigma associated with leaky type houses that do not leak. It highlights the financial/economic arguments that suggest there may be sufficient motive for the home owner to undertake an over-clad.

It points out some of the technical challenges of the approach at a headline level. It further comments on the assurances building consent authorities will need to permit over-cladding on a regular rather than ad hoc basis. It concludes with the recommendation that the Stage Two study should proceed. That study would place a dollar value on the stigma of being a leaky type home and the costs of recladding and over-cladding.
