Installing insulation can lower your bills

Insulation is a brilliant way of keeping heat in during winter months as well as ensuring your house does not overheat during hot Australian summers. By insulating your house properly, you can reduce your energy bills by up to 40%.  There are multiple types of insulation to choose from, whether it is roof insulation or installing double or triple glazed windows.

When installing insulation, it is important to go with a construction company or independent builder that is licensed to install insulation, as it is a costly process and you want to make sure that it is being done correctly.  Your home can lose up to 40% of its heat if you do not have the right type of insulation installed in the home, so make sure that you consult a professional who will advise you on what the most effective type should be put into the home.

For example, if you live in a property that has large windows that are constantly exposed during summer, heat will seep into the property and will make your air conditioning work twice as hard to keep rooms cool. A simple solution would be upgrading to double or triple glazed windows and installing blackout blinds that will block the sun’s rays and enable the property to be cooled down quickly. Investing in other types of insulation may not be as effective, as the large windows are the biggest contributor to heat and cold air being lost.

Another example is when heating the home, if you have draughty doors or thin cold walls, heat will escape much quicker than if you have insulation put in the walls and the doors replaced. It is all relative to the type of property that you are living in.


There are four key factors to consider when installing insulation:


Age of the home: Older homes are going to be more expensive to insulate, as they were built differently and are less likely to have insulated walls and double-glazing. Make sure before you have insulation put into the home that you see whether it is going to make a difference to the property you are in due to its age.


Climate: There are different types of insulation materials that can be used depending on the type of climate you are living in. For example, colder countries that experience winter weather more will have different types of insulation to someone who lives in a country where there is a lot of humidity and heat. It is all relative to the type of climate you are living in.


Budget: Do not invest in cheap insulation because you are unable to afford something that will do a better job in the long term. You will end up spending more money on energy and also getting the insulation replaced. You are better off saving up for the best insulation for your property so you are not wasting money in the long term


Type of property: Whether you are in a block of flats, or a detached four-bedroom house, the type of insulation for either property will vary. Make sure you get a consultation to see what kind would be best for you.
