We Insulate Your Home

Canterbury Insulation is a Christchurch based retrofit insulation company who specialise in insulating the existing walls and ceilings of your home. Insulation is the most important item you can fit to your home to create a warm, comfortable, healthy and energy efficient environment and our experienced team have been in the insulation retrofit business for over 15 years.

Insulating your home is a smart investment that will pay itself off relatively quickly, when you add up the savings to your energy bills.

Why should you insulate your home

While the recommended time to insulate is during the construction phase or a major renovation, here at Canterbury Insulation, our skilled team specialise in CosyWall Insulation, which is a high-performance wall insulation product that can easily be retrofitted into older homes. For the most beneficial experience, we recommend insulating all areas of your home, paying particular attention to the areas which lose the most heat in winter and gain the most heat in summer.

The roof and exterior walls are the biggest culprits for a home’s heat loss and gain. We also specialise in acoustic insulation in and around Christchurch and beyond, which will help to reduce noise transfer both inside and outside your home, creating a calming and welcoming environment.

To improve your comfort and create a more economical home environment today, call the leaders in insulation throughout the Canterbury region.
