Where the greatest heat loss occurs


Did you know that your home can lose as much as 30% of its warmth through the ceiling?  And up to 10% through the floor?  As registered installers, we can carry out home evaluations and subsequent insulation installations.

We guarantee our work and materials.  Our customers receive a compliance certificate on work completion.

Did you know you can lose up to a whopping 35% of heat through your ceiling? Having ceiling insulation helps to keep your home warm in winter, but also cooler in summer, how cool is that!  It also helps to make heating your home more cost effective.  Ceiling insulation can also help reduce noise and your power bill!

How much ceiling insulation will I need?

You need to meet the energy efficiency requirements set out in the Building Code, whether you are building a new home or making additions or alterations to an existing home.

The requirements vary for different parts of the country, to ensure New Zealand homes are fit for purpose. More insulation is needed for houses in colder climates.

  • Zone 1 – Northland, Auckland, Coromandel: R-Value 2.9
  • Zone 2 – Rest of the North Island except Central Plateau: R-Value 2.9
  • Zone 3 – North Island Central Plateau and all of the South Island: R-Value 3.3

Remember that these are the minimum levels of ceiling insulation when retrofitting to an existing house and it is often worthwhile to install at a level above the very minimum. We recommend asking for a quote on the minimum level plus a higher R-Value and then make a call for what your budget can afford.

“It’s been a pleasure working with you [Sandra] and Chris. You’re a dynamic team.”

Rob, Builderscrack 

I have been on the phone with Chris a couple of times concerning issues regarding the installation and he was really helpful, taking the time to explain what was the issue and what needs to be resolved before he can complete the job. It has been easy to reschedule jobs with you and I’m really thankful for your flexibility.
