How We Retrofit Wall Insulation Without Removing the Gib

Ceiling insulation is often the first place to start when you want a warmer home, and for good reason. Warm air rises, so a poorly insulated ceiling can let a lot of heat escape. But once your ceiling and underfloor insulation are sorted, the walls can still be a major source of heat loss. In many older New Zealand homes, wall insulation was never installed when the house was built. This can leave a large gap in the home’s thermal barrier, making it harder to keep warmth inside. The good news is that retrofit wall insulation is now a practical option, and we can install it without tearing your walls apart.

What is retrofit wall insulation

Retrofit wall insulation means adding insulation to the wall cavities of an existing home, without a full renovation. Older homes typically have a cavity between the internal lining and the external cladding. That space sits empty, doing nothing to keep heat in or cold out. Filling that cavity with insulation makes a big difference to the warmth and comfort of a home.

As an authorised CosyWall Insulation installer, we use a blown insulation system that is specifically designed for this purpose. It is one of the most effective retrofit wall insulation solutions available in New Zealand, and it has been installed in Kiwi homes since 2002.

How the CosyWall blown insulation process works

The CosyWall system uses blown insulation to fill wall cavities from within the home. Here is how the process works:

1. Small holes are drilled through the internal linings.
2. Insulation is blown in through the holes using specialist equipment. The material fills the wall cavity completely, getting into all the gaps and voids.
3. The holes are plugged and finished so that your walls are restored to their original appearance.

The entire process is designed to be as non-invasive as possible. There is no need to remove your gib board or deal with a major construction project inside your home.

Your home insulated in one day

One of the most practical benefits of this system is the speed of installation. Most homes can be fully insulated using the CosyWall blown insulation method within one day. You do not need to move out, and the disruption to your daily routine is minimal. Compare that to a full wall renovation, and the difference is considerable.

CosyWall Insulation delivers high installed R-values, which means the insulation performs well at reducing heat transfer through your walls. The result is a warmer home in winter, a cooler home in summer, and improved acoustic performance, which means less noise coming in from outside as well.

Who is retrofit wall insulation suitable for

The CosyWall system is suitable for most older New Zealand homes that were built without wall insulation. If your home was built before April 1978, there is a good chance your walls have no insulation.

It is also worth noting that wall insulation works best as part of a complete insulation package. Combining CosyWall with ceiling and underfloor insulation gives you the most complete thermal protection for your home.
