Insulation is a hot topic in New Zealand.  If 'cold' or 'damp' are words you’d use to describe your home or if you’re tired of high heating bills, insulation is a major part of the solution.

The Insulmax® Retrofit Wall Insulation System is designed to insulate the walls of all styles of New Zealand homes without renovation or removing wall linings. Installation uses the smallest holes made in the exterior or interior wall lining. The exterior cladding is left weathertight. Our aim is to leave no sign that your walls have been insulated.

Here's why we think Insulmax® wall insulation is a great choice for your home!

Insulmax offers affordable, hassle-free installation.

There’s no need for a full renovation!  The cost, mess and hassle of removing cladding is enough to put most people off the idea of insulating their home.  However, Insulmax® installation uses holes as small as a 10 cent coin in the exterior or interior cladding.

Installation usually only takes a couple of days, and your exterior cladding is left weathertight.  Holes are reinstated using a polyester filler, sanded and then primed / top coated.  Masonry claddings are reinstated with mortar – Insulmax aim to leave your property spotless with no sign that your walls have been insulated.

Insulmax is a warm and effective solution.

With Insulmax® installed, the ability of your home to hold heat will be a lot higher. You’ll notice your home is generally warmer and after a warm day it will hold its heat longer into the evening. When you turn on heaters the temperature will rise faster and the heaters will turn off sooner. You’ll notice that your heatpump operates at a lower level to keep the same temperature. When you wake up in the morning your home will be warmer and you might be surprised when you step outside and realise how cold it is.
