Lower carbon, versatile performance

Guardian NEXA 6 lower carbon glass has an embodied carbon value of 6.38 kg CO2e/m2 for a 4 mm glass thickness. This represents a reduction of more than 40%* when compared to the average EU float glass dataset, and more than 30% when compared to standard 4mm Guardian ExtraClear^™ float glass. Guardian NEXA 6 can be laminated and/or used as a base glass for all Guardian Glass range of products – such as the Guardian SunGuard™, Guardian Bird1st^™ Lami or Guardian ClimaGuard™ – to add features such as energy efficiency, bird deterrence, or sound reduction when laminated.

*When comparing A1-A3 GWP (Global Warming Potential) value of Nexa6 vs Sphera Database 2022 Dataset for EU-28 Float flat glass (valid as of December 2024), reduction calculated is -41.5%. A1-A3 embodied carbon value derived from the LCAs and pending verification for conformance to ISO 14040/44, EN 15804, and the Product Category Rules (PCR) through a program operator and independent reviewer.
