Top tier performance double glazing

PerformaTech™ is our range of double and triple silver high performance coatings that are designed to allow high levels of light transmittance in combination with low levels of solar heat gain and an excellent low U Value.

Particularly suited for medium to high rise facades and large glazed areas, the high performance characteristics of PerformaTech™ provide exceptional functionality and excellent design flexibility.

PerformaTech™ is the ideal solution for solar exposed elevations, where high levels of solar heat gain need to be addressed.

The spectrally selective coatings within PerformaTech™ maintain very high levels of light transmission.

With a clear to neutral aesthetic, PerformaTech™ includes a wide range of solar control levels to align with the stringent demands of regulatory requirements.
