PerformaTech™ Solar Control Low-E

Premium solar control low-e double glazing – for top-tier thermal insulation performance & light transmission.





We believe that light and comfort should go hand-in-hand. That’s why we created PerformaTech™ – giving you the opportunity to design beautiful, affordable and sustainable buildings.

PerformaTech™ balances high levels of light transmission with very low levels of solar heat gain to provide you with a brighter and more comfortable space.

Relax in Year-round Comfort

PerformaTech™ offers superior thermal insulation combined with solar control and light transparecy – keeping your space at an ideal temperature.

Create Beautiful Designs

PerformaTech™ offers a high level of design flexibility because of the high ratio of daylight to radiant heat.


PerformaTech™ can deliver other benefits when it is paired with other solutions including privacy glass or acoustic glass

Double Glazed Unit

PerformaTech™ offers exceptional thermal insulation combined with high light transmission through the use of low-e glass and inert gas filled as standard.

Low-E Coating

A premium double Low-e coating is applied to allow natural light through without emitting radiant heat, maximising light and energy efficiency.
