Colour Is Not Just A Pretty Thing, It Really Works

Colour has a big impact on the internal comfort of your home and in particular, we are discussing the external colour of your home.

As an example, we show you an image of a standard Melbourne rendered brick veneer home. The front is painted one half in a dark grey, the other half in a much lighter grey. Using an infrared thermometer, we took the temperature of those two different colours. The darker colour showing the temperature to be 56 degrees whilst the lighter colour showed 46 degrees.

This means that the dark wall conducted 22% more heat into the home then the lighter shade. This is particularly important to remember going into summertime, as the hotter the weather gets the more heat that can be conducted into the home just based on the colour of the walls.

In conjunction with this, we have also found that dark coloured roofs increase attic temperatures by 20 degrees. Even if a home has R4 insulation, the heat that is conducted is equivalent as having a blow heater on half blast.

When you are choosing new roofing or external paint for your home, it is important to bear in mind the impact that colour will have on the temperature of your home.
