Does your home feel like it could always be warmer or cooler?  Are you cranking the thermostat, have you serviced your appliances and still feel that 30degrees isn’t keeping your home warm?  Before you rush out and buy and new electric heater or split system air-conditioner have a look around your home, is it properly insulated?

Why is insulating your home so important?  Around 40% of your cool or warm air can leak out your home through gaps and cracks if your home is not properly insulated.  Insulating your home will help you reduce those heating and cooling energy bills.  By insulating your home, it will prevent you having to over work you heating and cooling appliances by preventing heat gain in summer and heat loss in winter.

When you have air leakage you’ll find you will be relying more and more on your electric heaters or reverse cycle air-conditioners with up to 40% of that lovely cool and warm air disappearing through your poorly insulated home.  Not only will this be increasing your energy bills it will also be shortening the life span of your appliances as they will be getting over worked to over compensate for the air leaking out throughout your home.

Before you rush out keep in mind that you don’t have to insulate your whole home to save on your energy bills if you’re on a tight budget, you can start small and work your way around the home.  A great first step would be to seal up gaps and cracks around doors and windows.  Start with the room you use most and ensure when you have your appliances running you have the room closed from the rest of the house.

Sealing gaps and cracks has never been easier if you’re unsure where to begin visit your local hard ware store and get some advice from them.  When you have seal off your main living area work your way around the home until you have done all your rooms and hallways.

Invest in appropriate window treatments such as blinds or curtains and use these to trap in that cool/warm air each day.
