Insulation

Homes built prior to 1978 are unlikely to have insulation, which is why they are colder and more expensive to heat than new homes.

Heat loss through the walls, floors and the ceilings in older homes can be reduced by installing additional or higher performing insulation such as Pink® Batts® Ultra™.

Ceiling Insulation
It is wise to insulate the roof space first because this is where the greatest heat loss occurs.

Wall Insulation
When renovating or redecorating, install insulation in exterior wall cavities to help prevent the walls becoming a weak point for heat loss.

Underfloor Insulation
Suspended timber floors can be insulated from underneath (provided there is sufficient crawl space). Wool carpet on floors also reduces heat loss.

Why it’s important to insulate your walls
Because it’s easier to gain access into the ceiling cavity of a home, it’s relatively simple to install ceiling insulation. However, insulating only the ceiling and not the walls leaves the walls as a weak point for heat to escape. Simulations show that insulating the walls and floor as well as the ceiling can more than double the benefit of insulation in terms of comfort and energy savings compared to insulating the ceilings alone. Installing insulation in the ceiling, walls and under the floors can reduce heating costs by as much as 50%.
