Product information
Overview
What is ceiling insulation?
Insulation slows the transfer of heat. In winter it stops warmth escaping through your ceiling; in summer it stops the sun’s heat getting in. This helps your home stay comfortable all year round and reduces the need for heating and cooling.
It is a high impact upgrade for older or poorly insulated homes, and one of the upgrades you may be able to choose through Home Energy Saver. The higher the R value, the better it performs.
A higher R value performs better, and R5.0 is a good benchmark for ceilings. Foil insulation has been linked to fire and electrocution and is not recommended in Australia.
suitability
Is it right for your home?
