YES – All types of external wall insulation, including Insulmax and common household name insulation products require an application to council for building consent or an excemption even when installed in a home that has been built for many years.  Some local councils have given Insulmax an exemption to this requirement and your local independent Insulmax license holder will be able to advise you of your local situation. Insulmax is fully compliant with the applicable New Zealand building code clauses and demonstrates compliance using the CodeMark Certification Scheme. The Insulmax wall insulation method has held CodeMark Certification since 2016 Don’t worry about the consent process, as all paper work and consent applications are made by your Insulmax representative.
