The sturdy cladding that a wolf couldn't blow through – but a winter chill can...

Solid and striking, "you can’t go wrong" investing in an older brick home. But for all its dependability, there’s something fundamental missing in your older brick home… wall insulation.

Why insulate the walls of your brick home?

Insulation reduces heat loss from your home allowing it to retain more heat making it warmer and easier to heat.  Heating bills can be reduced and your home will feel drier, quieter and generally a more comfortable and healthy place to live.  When you’re in a newer home, you’ll notice how easy it is to maintain a comfortable, dry and healthy indoor environment. Insulmax® can make this a reality in your older home as we increase your home's insulation to modern standards.

How we insulate your brick / block walls

Assessment

Comprehensive pre-assessment report of your home to ensure you and your family get the full benefit of Insulmax®.

Assessment

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. poorly sealed window/masonry joint. 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.

Installation

Wall cavities are accessed and filled with Insulmax® mineral fibre insulation, generally within a day. Leave a cold home in the morning and get back to an insulated one after work!

Installation

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. Each cavity is accessed by a small install hole made in the "T' joint formed where three bricks meet.
  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

Finishing your Install

Thermal imaging equipment is used to ensure all areas are insulated before install holes are filled and finished. Your install is covered by a written 50 year Insulmax® guarantee* to accompany the approved council application.

Finishing your Install

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 colour matched mortar and pointed to matched the existing mortar.  The small 16mm installation hole makes filling straightforward and the finished hole difficult to spot.
  2. Once the mortar is dry the entire wall is surface sealed with a surface sealer as an added level of insurance against water entering the bricks. Alternatively if the exisiting cladding is painted the filled install holes are painted with a primer and top coat** paint system to provide a weathertight and durable finish.
  3. 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 4.0 to the walls of a typical brick 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

What other brick/block home owners have to say about Insulmax®

We purchased a 1970s house in Tauranga and found the children's bedrooms (formerly a garage) were ice boxes in winter. We chose Insulmax® for wall insulation, and enjoyed a hassle-free, quick and professional service - and the team even installed an extra smoke alarm! The insulation significantly improved heat retention in the rooms. Insulmax® was a straightforward and cost-effective solution, adding considerable value to our home.

Battling extreme temperatures in our 60s brick home, we found the perfect solution with Tauranga Insulmax®. The results were immediate and impressive. We noticed that we didn't have to turn on the heat pump as often, and even when we did, we could set it at a lower temperature - an investment worth every penny! A game-changer and we highly recommend Barrie and the team for a hassle-free, renovation-free home upgrade

I just wanted to say that the wall insulation I got installed did everything you said it was going to do, and I am glad I got it done. I ended up doing the heating capacity requirements myself and realized that the wall insulation hadn't been added into the calculations, and that when it was added, my heating was compliant. The double glazing of the windows (or not) did not change anything compared to the walls. So wall insulation is cheaper and does better to keep you warm!

Our house definitely holds the heat in better since Insulmax®, it was still tee shirt weather inside with single digits outside this morning. We let the fire burn out early with all the internal doors open.

Having our walls insulated was absolutely the best money we've spent on our house so far. We thought the double glazing was going to make a big difference to us but it really didn't have much of an impact. Now we've had our walls insulated we can really feel and hear the difference.

So we went ahead and got Insulmax® put in the walls and that first night was an eye-opener what a difference it made, for the first time in the twenty years of living in this house my wife said the room got too hot and had to turn off the electric fire. We have also redecorated. So having Insulmax® in our walls has given us smaller power bills and a house that is now a lovely warm and cosy home.

After installation, we often get up in the morning after a cold night and have no idea of the cool temperature outside because the house was so warm. The surprising benefit is Insulmax® insulation blocks a lot of noise from nearby roads. After nine months we still can’t believe it’s made that much of a difference.
