Insulation for ceilings is usually the cheapest and easiest form of insulation, and will make the biggest difference to home heating bills because approximately 30% to 35% of heat loss is through the roof.
For best results, it is important to use a quality product, as well made ceiling insulation is more likely to do its job and remain effective for years to come.
There is a wide variety of ceiling insulation products available on the market that are safe to use and extremely effective.
Different homes require different products
Different homes suit different products, so it is important to find the best appropriate product. It is also essential that the insulation is installed correctly because any gaps or folds will allow heat to escape.
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 mask during installation.
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 non-itch and 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 homes warmer.
