Your home needs insulation because heat moves naturally away from warmer areas to colder areas.
On hot days heat tries to get inside your house and on cold days the heat tries to escape.
Adequate insulation in the ceiling, underfloor or walls of your home will minimise the transfer of heat.
So, your house will be warmer in winter and cooler in summer.
Installing sufficient insulation is the single most effective action that you can take to increase your comfort levels, save energy and lower your power bills. Full home insulation may lead to a 50% saving on heating requirements.
