The Real Cost of Doing Nothing

Uninsulated Walls
Will Cost You

01

Your Heat Is Escaping

Up to 40% of the heat you pay for walks straight out through your walls. Your heat pump is working overtime — and you're footing the bill every month.

02

Power Bills Keep Rising

Heating an uninsulated home in Christchurch winter is like leaving a window open. Your walls are the single biggest upgrade you can make to reduce running costs.

03

Cold Rooms Affect Health

Cold, damp homes are linked to respiratory illness, poor sleep, and worse wellbeing — especially for young children and the elderly. Insulation isn't just comfort, it's health.

04

Summer Is The Time To Act

Most people wait until they're already freezing. Book now while the weather is fine — installation is faster, easier, and you'll be fully warm by the time winter hits.
