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.
Insulation for your ceiling is usually the quickest, 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. So insulation is the logical first step. Ask us about what subsidies and finance options are available.
We only use proven ceiling insulation products that we are confident will last and are backed by significant manufacturer warranties.
Mammoth Ceiling Insulation: Our first choice for ceiling insulation is Mammoth polyester insulation. We favour it because it is NZ made, non-irritant, safe & easy to use, and the polyester fibres have a permanent heat bond that is long lasting.
Pink Batts Ceiling Insulation: Pink Batts glasswool insulation is also made in New Zealand. It is a familiar building material from a trusted manufacturer. Pink Batts has an excellent reputation and has been keeping New Zealand homes warm for over 50 years.

6 questions & answers about this product
How much insulation do you need in Ceilings?
The thermal effectiveness of insulation is measured by its thermal resistance or R-Value. The New Zealand Building Code specifies minimum R-Values for ceiling insulation in different regions reflecting the climate.
- Northland, Auckland, Coromandel: R-Value 2.9
- Central Plateau: R-Value 3.3
- Rest of the North Island: R-Value 2.9
- 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. Request a quote on the minimum plus a higher R-Value and make the call for what your budget can afford.
What insulation material is best for Ceilings?
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 Warmer Kiwi Homes insulation programme for homeowners. The two most used ceiling insulation materials are polyester and fibreglass (glasswool) insulation.
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 Pink Batts and Bradford Gold glasswool insulation - both are trusted brands for ceilings and walls.

Are there types of insulation are there for ceilings?
Ceiling insulation is available is blanket rolls, sections/segments and loose-fill insulation.
Insulation 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.
Insulation Segments: The insulation is pre-cut into rectangles that sit between the timber framing in your ceiling. These are effective although heat can be lost between the segments.
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 if your insulation was installed before 2005 it may not have been enough. In addition some forms of ceiling insulation settle over time becoming less effective.
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. Contact us to get a free home assessment.
Should LEDs be upgraded at the same time as insulating?
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.
Can all ceilings have insulation retrofitted?
If your home has a roof space sufficient that our installers can crawl around - then yes your ceiling can be insulated with ceiling blanket. We can also help fit a manhole for access if that is the only issue.
If your ceiling is too small for people to crawl around in - then in most regions we can assist with a blown-in insulation solution. Blown-in ceiling insulation can settle over time but it is better than no insulation at all.
