The Insulmax®
Retrofit Process
Pre-assessment of your home to ensure you get the full benefit of Insulmax® insulation
Step One
Step Two
All wall cavities are located and accessed through holes smaller than a 10 cent piece, then completely filled with Insulmax® blown fibre insulation
Exterior cladding is finished and left durable and weathertight
Step Three
A final check with infra-red thermal imaging ensures the wall is completely insulated
Step Four
Yes – Insulmax® is Certified to insulate the walls of older New Zealand homes!
The Insulmax® Retrofit Wall Insulation Method is CodeMark certified. CodeMark Certification is administered by the New Zealand Government and is the highest form of product assurance in New Zealand. External auditing by Bureau Veritas ensures that our high levels of quality are always met.
YES – Insulmax® insulation can be installed in wall structures with or without building paper. Insulmax® insulation is highly resistant to absorbing or wicking liquid water so it does not require the additional protection from water that conventional insulation products require.
Most homes in N.Z are composed of vertical, horizontal, and diagonal timber framing called studs or bracing. We use a variety of techniques to find the cavities formed by these timbers, including high resolution thermal imaging which some customers compare to an X-ray of their walls.
Our installation machinery is designed to fill wall cavities and works in a similar way as a petrol pump turning off when your fuel tank is full. We also use thermal imaging cameras as a final check to assure that no cold areas of wall have been left uninsulated.
YES – most brick homes are built as a masonry cladding over a conventional timber framing although some are a double brick construction. We can insulate masonry clad homes through small holes made in the “T” joint of the exterior brick cladding. Alternatively, we can install via the internal lining, which works well if the plan is to redecorate.
NO – Insulmax® mineral fibre insulation is installed under slight pressure and is packed into the wall cavity so it cannot slump, settle, or shrink. The product has an E.U. Standard rating of S1 in relation to settling. This rating corresponds to settling measured below 1% or unmeasurable.
The installed density of Insulmax® is over 50% denser than most conventional segmented fiberglass insulation products which contributes to its stability and high thermal and acoustic insulation properties.

The benefits are incredible! Our winter power bill has gone from $300 to around $150 a month. The house is super quiet. No mould on walls! No wet walls in our bedroom! This was the best thing we have done to our house. We now have a healthy home for our young family!

Insulmax estimated a 5-degree improvement. We achieved 7! I’ve found I don’t need the heat pump on until early evening even then it doesn’t run full output like it used to, the house warms up and stays warm.
Jess
Having our walls insulated was the best money we have spent on our house so far, we thought the double glazing would make the difference, but to us it didn’t really have much of an impact. Now that we have had our walls insulated, we can really feel the difference.
