A Clear Transmission

Guardian Sunguard Snx 70 glass offers light, comfort and energy efficiency.

Guardian Glass Europe has launched the latest product in its SunGuard eXtraSelective range – Guardian SunGuard SNX 70 which is a triple silver-coated glass that ramps up solar control and light transmission to almost 70%.

The glass also offers high thermal insulation.

It has a clean, natural appearance and a subtle reflective quality that achieves a uniform aesthetic across design contours and different viewing angles.

This means SunGuard SNX 70 offers architects the opportunity to introduce more natural light and improvements in energy efficiency and comfort for inhabitants, that can lead to enhanced wellbeing for occupants – particularly relevant for office, healthcare and educational buildings.



The glass is especially effective when combined with Guardian UltraClear as a base – available as SunGuard SNX 70 Ultra. In standard double insulating units this provides 68% light transmission, 32% solar factor, and a Ug value of 1.0 W/m2K. In standard triple glazed units it offers 62% light transmission, 30% solar factor and a Ug value of 0.5 W/m2K.

The glass’ transparency also means that views from both inside and out are truer in colour.


Environmental Product Declaration

SunGuard SNX 70 can also assist environmental certification. As part of the SunGuard range in Europe and Russia, SunGuard SNX 70 has an EPD (Environmental Product Declaration) and has been independently assessed under the Cradle to Cradle Certified Products programme, where it is certified Bronze.
