Energy Efficiency

Sunergy® Low-E Coated Glass

Sunergy® glass is a toned low-E coated glass, combining improved solar control and thermal insulation over standard clear glass.

No need to sacrifice natural daylight

Sunergy’s unique coating acts like a filter, blocking out the sun’s direct energy whilst maintaining a high level of natural daylight. The same coating helps to reflect heat back into the building on cold days.

This means better energy control with lower cooling and heating costs. Sunergy® glass also has a low visual reflectance with a lower level of haze compared to other low-E coated glass products on the market.
