Reducing Heat: How Roller Shutters Work:

Now, let’s address the burning question: Do roller shutters reduce heat? The answer is a resounding YES

Roller shutters are excellent at minimizing the impact of the scorching Australian sun on your home’s interior. Here’s how they work:

1. Solar Heat Reflection:

Roller shutters have reflective surfaces that bounce off the sun’s rays, preventing a big part of solar heat from entering your home. This feature is especially beneficial in regions with extreme heat, such as Adelaide and Perth, where summers can be brutal.

2. Insulation Properties:

Window shutters create a barrier between your windows and the outside environment. This barrier acts as an insulator, reducing heat transfer. 

This means that during summer, the cool air inside your home stays put, and the oppressive heat outside is kept at bay. Likewise, in the winter, window roller shutters help retain warmth, resulting in energy savings all year round.

3. UV Ray Protection:

In addition to reducing heat, roller shutters also protect your home’s interiors from harmful UV rays. Prolonged exposure to UV rays can lead to the fading of furniture and upholstery. By blocking these rays, roller shutters help maintain the longevity and vibrancy of your indoor furnishings.

External Roller Shutters FAQ:

Here are most of the common questions from our customers about the performance of external roller shutters during the scorching Australian summer:


Yes, by adding roller shutters to your window you significantly reduce the airflow that can enter and escape your home.

You can have the roller shutters halfway up or down or anywhere in between to adjust how much airflow you want in the home.


Yes, your room will be very cool when you have the roller shutters down.

They eliminate sunlight coming through the window, which is the reason why your room will get very hot in the Australian climate.

Window roller shutters will eliminate the root cause of the problem with rooms not staying cool, which is especially good if you sleep during the day, have a newborn at home or just need a way to cope with the unbearable heat of the day coming through a particular window in the house.


Yes, because of the added insulation that roller shutters have on a window you get the bonus impact of keeping cold air out of your home, and in turn, reducing heating bills.

For example, if you run your hand near a window, it may feel colder than other places in the house. That is the exchange of thermal energy happening. However, the exchange of heat is reduced when you have roller shutters at home.

The insulation foam inside the roller shutter slats is especially good for added insulation, which many roller shutter companies do not include in their roller shutter product.


Yes, by ensuring you keep your home insulated, your home becomes much warmer and you rely less on heating and rising energy bills to keep your home warm.

Keep in mind that a window is the number one area of a house where heat will escape. So installing roller shutters is key to keeping your home warmer throughout the year.


Roller blinds, much like roller shutters, will keep heat inside your home by reducing the easiest route for airflow to escape the home.

Think about this: Airflow is similar to water in the fact that it is the easiest route to take. Air will flow in and out of the house and exit through the windows.

You will notice this effect if you have the front door open and the back door open, and the airflow going through the house can ensure your house stays cool in the summer.

By adding roller blinds, you are making that route harder for the air to escape. It may take a different route, but the air will have a much less optimum route to escape by installing roller blinds.


In a similar way to roller shutters, plantation shutters are a type of window shutter that blocks light coming into the home and warms up a room.

By eliminating the light coming into your property, you stop the heat at the source and heat from building up and making you uncomfortable.
