CosyWall Retrofit Wall Insulation

What is CosyWall Retrofit Wall Insulation?

CosyWall is a special dry fibre glass wool insulation. It's manufactured as a high-performance wall insulation product that's easily retrofitted into older New Zealand homes.

CosyWall is only available authorised installers like Pilkington Insulation. It's installed through the interior or exterior walls of the home. Once installed, the holes are repaired and painted over so you'll never know the job was done.

CosyWall has been installed in New Zealand homes for more than 20 years. It's a proven wall insulation product installed in thousands of Kiwi family homes. Wall insulation completes a home's thermal barrier, keeping it warm and dry all year round.
