Thermal-breaks key for healthy, people-centric buildings and affordable living. 

Common misconceptions are that thermal-break systems are only useful in cold climates, double-glazing is the benchmark or they're too expensive. This is not the case...

These misconceptions are resulting in poor building design decisions that impact peoples cost of living, their health and the environment. 


As much as 49% of the heat lost in winter and as much as 87% of the heat gained in summer can come from the windows.


Thermal-break systems can actually reduce heat loss in a colder climate and reduce heat gain in a hotter climate.

Double-glazing may be an improvement, but the potential energy efficiency is greatly reduced when used with a standard non thermal-break aluminium frame, as our results show. 


Upfront costs of thermal-break systems may typically exceed standard systems, however, the lifetime cost savings on energy and health clearly make thermal-break systems, such as e2alu™ and e2tim™, the better decision. 

Benefits of thermal-break systems

  • Improve energy efficiency
  • Reduce heating and cooling costs
  • Improved health and well-being
  • Cost competitive with double-glazing
  • Australian manufactured

So what is a thermal break?

Thermal breaks are typically a polyamide strip positioned between the aluminium exterior and interior frames.


It creates a barrier to reduce the transfer of heat and cold through an aluminium window or door frame resulting in excellent insulation while maintaining the structural integrity of the system.


Thermal break strips are generally black in colour, but are represented in blue to identify them.

The results are clear...

It only takes 3 minutes for the double-glazed standard non thermal-break aluminium system to fail at stopping both hot and cold temperatures transferring from outside to inside.
