In Australian homes, heating and cooling make up about 38% of energy usage. Without proper insulation, much of this energy is wasted through walls and ceilings, forcing heating and cooling systems to work harder.

Insulation traps air, slowing heat transfer through convection and conduction.

Earthwool insulation, for example, prevents air movement, while advanced technologies like those from Knauf Insulation enhance air entrapment for greater energy savings.

By reducing reliance on heating and cooling, significant savings—up to 48%—can be achieved compared to uninsulated homes.

This applies to both residential and commercial buildings.

Higher R-values are necessary for insulation effectiveness, especially in environments with large temperature differences between indoors and outdoors.

Incorporating high-quality insulation above minimum standards enhances energy efficiency and indoor environmental quality in homes and businesses.
