Ceiling Insulation for Kiwi Homes.

Up to 35% of heat is lost through the ceiling in winter if you have no insulation in your roof. Retrofitting ceiling insulation will keep you warmer in winter and cooler in summer and is a requirement for rental properties.
Ceiling insulation in your roof is usually the quickest, cheapest and easiest insulation to retrofit and will make a huge impact on your heating bills by limiting heat loss.

Ceiling Insulation Subsidies

Some homeowners are eligible* for 80%-100% insulation subsidies. Ceiling Insulation subsidies are region specific and T&Cs apply yet we make it easy. See if you're eligible today for ceiling insulation subsidies- no obligation.

Ceiling Insulation Interest Free

Making ceiling insulation affordable, we also help with a range of low/no interest payment options whether or not you're not eligible for subsidies.

Ceiling Insulation Reviews

Boys were efficient and hard working, they left with the place tidy and did a excellent job. As soon as I know someone that will benefit from this I will be recommending you.

Noella, Otago

The installers were quick and polite, house trained and professional. The telephone team/admin people were great too. Our house is so much warmer. We will definitely call up the team to do our next home.

Pip, Northland

All good at my end, the guy who did the job was excellent. Not only was he out of here in 3 hours but I checked the work after the fact and it was impeccable. Many Thanks.
