The highest percentage of internal air temperature escapes through the ceiling, making this the ideal place to begin upgrading insulation levels. Ceiling insulation will act as a blanket, trapping the transfer of air coming in and out of the home. With almost 35%1 internal temperature escaping through the ceiling, installing insulation will not only improve the comfort of the home but also save up to 30%1 on heating and cooling energy bills.
Glasswool insulation is the most common insulation used in ceiling spaces. Made using recycled glass, it is non-combustible and is one of the most sustainable insulation products on the market. Developments in insulation manufacture have also contributed to improving the handling of glasswool, and products such as Earthwool® glasswool are softer and less itchy than traditional glasswool products, making it much easier to handle and install. Also, look out for insulation with no added formaldehyde for further peace of mind.
Ceiling insulation is easy to install and can be done as a DIY project. For guidance on installation in New Zealand reference NZS4246:2006 and our installation instructions before carrying out any work.
