Just like an esky in summer or a warm coat in winter, insulation works by slowing down the transfer of heat from inside to outside and vice-versa. It does this either by trapping air using bulk insulation, or by reflecting heat using foil insulation. By slowing down the transfer of heat you don’t have to use heaters and air conditioners as much. And when you do, you can use them for a shorter time and with greater effect. It’s just like a tea cosy for your house!

Most homes don’t have enough insulation

Most homes built prior to 1990 don’t have wall insulation and over 40% of Victorian homes lack adequate ceiling insulation. If you have some old existing insulation it is not usually necessary to remove it – you can simply add more on top.

A lot of homes have insulation but it has been moved by tradespeople, when they have gone in the roof space to do work such as electrical work, NBN installation, air cons, solar etc. If you can access your roof space to take a look you might be able to move the insulation back to where it belongs, to decrease gaps.

Ceiling insulation is the most important but don’t forget walls and floors! You wouldn’t go out in winter wearing only a hat, so insulating your walls and under your floor is like adding a good coat and warm boots to your home’s beanie!

Insulating your ceiling, floors and walls can save you up to 65% on the heating and cooling energy costs of your home. In addition, insulation may reduce condensation and can also make your home more soundproof.

Here’s a handy video to help explain the benefit of insulation (with some help from some coffee cups!).

Is ceiling insulation safe? I’ve heard it can cause fires.

Ceiling insulation is safe, but it is important to have it installed by trained professionals to avoid any risks. Positive Charge has carefully selected expert suppliers, who can assess your situation and take any action needed to protect your home, such as ensuring that downlights are properly covered.

Is it a good investment?

Definitely! As well as improving the comfort of your home in winter and summer, improving the thermal performance of your home will save you money on your bills.

Making your home cheaper and easier to keep at a comfortable temperature can also improve health outcomes, especially for vulnerable households. According to a recent study published in medical journal The Lancet, cold contributed to about 3.9 per cent of deaths in Sweden, but 6.5 per cent in Australia. The reason for this is that it’s not the extreme events like blizzards that cause the most deaths from cold but medical issues like increased blood pressure from constant exposure to low temperatures.
