Ceiling Insulation: Best Advice, Quotes and Installation

The best place to start insulating your home is in your ceiling as most heat is lost through your roof. Fitting quality ceiling insulation will keep you warmer this winter.

Ceiling Insulation: the best way to warm homes

Up to 35% of heat is lost through the ceiling if you have no insulation in your roof.

Insulation for your ceiling is usually the cheapest and easiest form of insulation and will make a huge impact on your heating bills. Adding more heat without preventing heat loss is an expensive way to address the comfort of your home.

Smart Energy Solutions has a range of insulation products for ceilings available and are experts - having installed insulation in ceilings and underfloors of over 34,000 NZ homes.  

We can give you free advice and help you choose from the best brands of polyester and fibreglass ceiling insulation. As an approved provider in EECA's Warm Up New Zealand: Healthy homes programme we have subsidies available for ceiling insulation in eligible rental properties. Don't hesitate - contact us today.

Ceiling Insulation Types in NZ

There's a variety of ceiling insulation product types available in New Zealand now. For best results choose quality ceiling insulation that won't settle or degrade over time. We only use ceiling insulation that has been approved for use in EECA's Warm Up New Zealand: Healthy Homes insulation programme.

Polyester insulation: A more modern insulation material is polyester which is the same sort of fibre as used in clothing, pillows and duvets. It's safe to touch, non-itch, non-irritant and also has no glues, resins, pesticides or formaldehyde. The polyester fibres are heat-bonded together for a long-lasting bond to keep your home warmer. Mammoth Modern Insulation is a polyester product and uses fibres from recycled plastic bottles in its manufacture as well.

Fibreglass (Glasswool) insulation: This is the traditional insulation that New Zealanders know and is made from spun glass fibres that are held together by glues and resins. Greater care must be taken when handling fibreglass or glasswool as it can cause irritations to the skin, eyes, throat and nasal passages. You need to wear goggles, gloves, overalls and a face ask during installation. We use Bradford Gold fibreglass insulation which is a trusted brand for ceilings and walls.

Ceiling Insulation Formats

Sections:  The insulation is pre-cut into rectangles that sit between the timber framing in your ceiling.

Blanket: This is a long roll of insulation that literally blankets your ceiling. It has the benefit of less joins that heat can escape through and covers the timber to avoid thermal bridging.

Loose-fill insulation: This is a form of ceiling insulation we only recommend for difficult to access roof areas. Loose-fill insulation is blown into the roof using a machine. It can be messy and can blow around in roof spaces after installation or settle with time.

Do I have enough Ceiling Insulation?

You may already have ceiling insulation in your roof space but is it enough? Standards have changed and some forms of ceiling insulation settle over time becoming less effective. The Energy Efficiency and Conservation Authority has prepared this handy video so you can check whether you have enough. If you don't have sufficient we can help you with top-up ceiling insulation to lay over what you already have to improve efficiency.

Better still, we install it for you to current New Zealand standards and we audit the installation of your ceiling insulation as well for complete confidence. It is essential that your insulation is installed correctly in your ceiling because any gaps or folds will allow heat to escape and poor installation around chimneys and downlights can be a fire hazard.

Our installation service covers Northland, Auckland, Waikato, Bay of Plenty, Taranaki, Hawkes Bay, Manawatu, Wellington, Canterbury and Otago.

Finance & funding for ceiling insulation

Because ceiling insulation increases the energy efficiency of your home so much there are a variety of options to help make purchasing ceiling (and underfloor) insulation easier. Some people can virtually pay for their insulation with the energy savings they make.* And importantly insulation contributes to the health of your family to keep the cost of sick days and doctors' visits lower.

Some finance and funding options are:

  • EECA subsidies for eligible rental properties,
  • interest-free mortgage top-ups
  • interest free finance offers
  • council targeted rates programmes in Auckland, South Waikato, Hawkes Bay, New Plymouth, South Taranaki, Wellington, and Dunedin

We can provide information and assist with some of the paperwork at your free home assessment.

* Dept of Building & Housing, Your Guide to Smarter Insulation estimated an energy saving of approximately $760 per year.


LED downlights: Best added with Ceiling Insulation

Insulating your ceiling is also a great time to consider switching to energy efficient LED downlights. In addition to having lower energy consumption you can reduce heat loss through the light fitting and reduce or eliminate the air space required in your insulation around traditional downlights. Read more about LED lighting.
