No compromises
on performance
Maintains the transparency and aesthetics of standard glass and can be combined with glass technologies that provide thermal insulation, solar control, or noise reduction
*The cradle-to-gate (i.e. from the sourcing of raw materials to the manufacturing site gate) embodied carbon value of Guardian NEXA 9 is 8.58 kg CO2eq/m2 per 4 mm glass. This represents a reduction of ~10% compared to Guardian ExtraClear™ standard float glass, which has an embodied carbon value of 9.64 kg CO2eq/m2 for 4 mm glass. These values are derived from third party verified Environmental Product Declarations.
