Wall insulation for 
your fibre cement board home

A trained and licensed Insulmax^® building assessor completes an assessment of your home to ensure the most efficient install process. We may also identify small areas of maintenance e.g. badly damaged boards. The thirty two point property assessment is free of charge and can be carried out without accepting a quotation. 

During the assessment a quotation can be prepared and options for your install discussed. Because Insulmax^® is certified to be installed via all common external claddings or internal linings the choice is largely down to customer preference.

Upon acceptance of your quotation, your Insulmax^® representative will prepare and lodge (on your behalf), an application with your local council* for a Building Consent or Sch1 Sec2 Exemption.  We strongly advise that you keep a copy of the council approved application or council letter advising widespread exemption for your records. This  is particularly valuable when the time comes to sell your property.

* Since 2010 all forms of external wall insulation have required an application to your local council for either Building Consent or Exemption, although some councils offer a more widespread exemption. Your local Insulmax^® representative can advise you of your councils requirements.

The installation of Insulmax^® is carried out by trained, licensed and audited Insulmax^® installers to the standards of Insulmax^® NZ Ltd. We absolutely pride ourselves on the professional knowledge of our staff and the quality of our installs.

The process involves :

1. All wall cavities are located by various techniques including the use of high resolution thermal imaging equipment.
2. A 16mm (smaller than a 10 cent coin) hole is used to access each cavity.
3. Install machinery is proprietry to Insulmax^® and is calibrated on each install to achieve the optimum density. A sample box is filled and weighed to ensure complete cavity fill and correct density. At correct density Insulmax^® will not settle or slump.
4. All wall cavities are filled with Insulmax^® mineral fibre insulation. Insulmax^® is installed dry with no binders, glues, formaldehyde or volatile compounds so it's safe to stay home during the install.
5. High resolution thermal imaging equipment is used during the install to ensure that all wall cavities have been filled with Insulmax^® insulation

Our aim is to leave your home with negligible sign that it's been insulated and we pride ourselves in finishing your home as if it were ours!

The process involves :

1. Each install hole is filled with a two part filler. The small 16mm installation hole makes filling straightforward and the finished hole difficult to spot.
2. Filler is sanded flush.
3. Smooth filler is painted with a primer and top coat** paint system to provide a weathertight and durable finish.
4. Seven to fourteen days after completion you will receive a written "Insulmax^® Certificate of Completion" guaranteeing your install for 50 years which we recommend you keep with your council consent paperwork.

Insulmax^® insulation contributes an R value of 2.8 to the walls of a typical fibre cement board home - you’ll want to adjust your heating settings accordingly!

* Each install is accompanied by a 50 year guarantee except external paint systems which are guaranteed for 7 years

** Top coat can be provided by the customer or by your installers, by prior agreement with your Insulmax^® representative
