Installing ceiling insulation can reduce your annual power bill by over $120 and lowers your household's carbon pollution by 500kg.
Ceiling insulation keeps your home cooler in summer and warmer in winter. It helps your heating and cooling systems run more efficiently, saving you money and reducing our impact on the environment.
How much insulation you need depends on where you live.
To get the most from your insulation:
- consider is its R-value – the higher the R or thermal value, the better it insulates
- choose the right type of insulation for your needs – reflective insulation (shiny foil) reflects sunlight away from the home, while bulk insulation (batts, blankets, rolls or boards) has good soundproofing qualities
- follow the manufacturers' installation instructions – if bulk insulation is flattened it won't work as well and reflective insulation needs an air gap next to the shiny surface
- make sure corners of ceilings, walls and floors are properly insulated – this is often where heat leaks are found
- avoid gaps - even a small gap can reduce insulating benefits by 50 per cent
- combine with effective window shading – keep your blinds down in summer on north-facing windows and leave them up in winter
- consider wall insulation for the cavities of exterior walls – where there is an opportunity during home building or renovation
