Retrofitting your wall insulation is key for a warmer, drier home

Homes lose up to 40% of their heat through the walls so after your ceiling insulation, wall insulation is the next thing you should look at installing.

Insultech Insulation supplies and installs blow in CosyWall insulation, which can be installed as part of renovations or retrofitted to existing homes throughout Waikato and the Bay of Plenty. We've been using CosyWall since it first came onto the market and we know what a difference it makes.

CosyWall has been the insulation of choice in New Zealand for more than two decades

CosyWall has been installed in New Zealand homes for more than 20 years, and over time the product has been refined and improved.

It provides excellent thermal and acoustical insulation which can be added to existing wall cavities without the need to remove the internal wall linings. Instead, the insulation is blown in through small holes made in the external cladding or the internal linings.

CosyWall products are Codemark certified and regularly audited for quality.

Frequently asked questions

Does the insulation shrink or slump?
No. CosyWall is installed to a very high density so it won't slump or shrink. The high-quality product is long-lasting and doesn't deteriorate over time.
Can you install into brick houses?
Yes. CosyWall is made in Europe and designed for the double brick cavity homes found in Europe. It can be installed against damp or wet surfaces and has specially designed water-repellent fibres.
Can I install from the interior and exterior?
CosyWall Insulation can be installed from the inside and the outside of your home. However, internal installations are best done if you are already renovating or redecorating the inside of your home. Exterior installation is easier and can be done at any time.
How long does it take to install?
You'll be surprised by how quickly we can install CozyWall in your home. In most cases, it can be done in a couple of days, but that depends on the size and layout of your home. Get in touch to get started.
