How insulation saves money in summer as well as winter
While you may associate insulation with the cool winter months, it can be just as effective at keeping you comfortable during the summer.
Insulation can stop chilled air from escaping, which may mean you see some savings on your electricity prices as you may not need to rely so heavily on your air conditioning unit.
The Department of Industry state households could save up to 40 per cent in heating and cooling costs through effective insulation.
What are the different types of insulation?
There are two different kinds of insulation you can choose from - bulk and reflective. You could even opt for a mix of the two.
When choosing the type, you will need to consider the climate of your location, the design of your home and its orientation.
If you live in one of Australia's cooler areas, this might be the way to go. Bulk insulation is made from batts, rolls and boards of glass wool, polyester, recycled paper or natural wool.
It works by creating a barrier that prevents heat from entering in the summer and escaping in winter.
This type of insulation may be better in the warmer months as it works by deflecting the sun's heat.
Usually made with shiny aluminium foil laminated onto paper or plastic, this type is best for households located in hotter climates.
Top two places to insulate: Roofs and walls
The most important part of your home to insulate is the ceiling. However, insulating the walls can also make a huge difference.
Draught-proofing is another important step to prevent cooled (or heated) air from escaping or leaking out from gaps and cracks around windows and doors.
This means you may see lower bills coming from your electricity suppliers as you use less power.
Roofs and ceilings
Your Mum may have told you to keep your head warm as you lose heat through the top of your head. This also goes for your house. Around 45 per cent of heating and cooling can escape through the roof, according to the Department of Industry.
If you live in in a hotter climate and have a verandah roof, this should also be insulated to reduce the heat from the sun warming up your house.
You can also insulate the sides of your house for a 20 per cent reduction on heating and cooling costs.
This is of value no matter what climate you live in, unless of course, your house is made from straw bale or autoclaved aerated concrete.
Wall insulation can be retrofitted if your house is not already insulated or if your current installment is not sufficient to keep your house cool in summer or warm in winter.
