Insulmax® Through
Your Interior Lining

Did you know we can also Insulmax® your walls from the inside ?

We can easily insulate the walls of your home through the interior plasterboard linings. This is particularly useful if you are planning on redecorating, as we can insulate before you prep walls for paint or wallpaper.

Whilst some homeowners undertake the daunting task of removing plasterboard or sarking to add segment insulation, this is an expensive, inconvenient and obtrusive option and often strips older homes of their character. It's also worth considering that sarking was intended as a structural bracing element and shouldn't be removed unless remedial bracing has been considered.

Insulmax® retrofit wall insulation is the perfect way to finish you home's insulation and bring it to closer to a new home standards.

Why insulate your walls?

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 confortable 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 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. damaged wall linings. 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. 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

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 neat and tidy with minimum sign that it's been insulated.

The process involves :

  1. Each install hole is filled with a plaster based filler during the install. The small 16mm installation hole makes filling straightforward and finishing straitforward. Holes made in interior linings will be filled with plaster and left proud to be finished when the plaster is completely dry by the customer or their agent.
  2. 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 weatherboard home - you’ll want to adjust your heating settings accordingly!

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

We already had insulation in the roof and floor but thought we could add the extra warmth by insulating the walls. It absolutely added warmth to the house and made a huge difference.

Ellyn's 100 Year Old Villa

Otago and South Canterbury

This is the very BEST money I’ve spent on my 100+ year old villa. The difference was instant. My home doesn’t get to 5-6 degrees anymore. My home doesn’t take long to heat, also the heat is retained and there have have been days during winter when I didn’t light the fire.

Debbie's Quiet Dry Home

Auckland and Northland

Almost two weeks on and I no longer have any traces of condensation on my windows. I can honestly say that my house feels warmer and drier inside and the road noise is reduced. The finishing to my weatherboards have been left in a ready to paint stage which is better than what they were prior to installation and your installers cleaned up after themselves.

I have been amazed by the difference it has made. My home is retaining the heat this winter. My power bill has significantly reduced and in fact since having the insulation installed I am saving nearly $100 a month on electricity costs! So pleased I invested in this.

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.
