NEXA 6

Lower carbon, versatile performance

Guardian Nexa 6 has a reduced embodied carbon of more than 30% compared to standard 4mm Guardian ExtraClear™ float glass. This equates to an embodied carbon value of 6.38 kg CO2e/m2*. It can be laminated and/or used as a base glass for all Guardian Glass products, such as our SunGuard, ClimaGuard, or Bird1st Lami range of products to add features such as energy efficiency, bird deterrence, or sound reduction when laminated. 

*The embodied carbon reduction was calculated by comparing the estimated value for 4mm Guardian Nexa™ 6 glass produced at our Guadian Glass Goole plant in the UK, and the estimated average value for 4mm Guardian ExtraClear™ glass produced in our European plants. The average embodied carbon value for Europe is based on the product’s Embodied Carbon Factor (ECF) which was derived from the regional Life Cycle Assessment (LCA), using 2021 data from all Guardian Glass European plants, considered to be a representative average. The Guardian Nexa™ value and regional European average embodied carbon value are pending verification for conformance to ISO 14040/44, ISO 21930, and the Product Category Rules (PCR) through a program operator and independent reviewer. Numbers are subject to vary due to the critical review process. The new Guardian Nexa™ EPD and EU regional EPD are expected to be published by mid-2024.
The embodied carbon data is the CO2 equivalent in kg per square meter of glass (CO2 eq.), emitted during the glass production (A1-A3), and was calculated using a standard 4mm thickness, not the actual glass thickness. The A1 – A3 stages include the environmental impacts from the raw materials extraction and processing stage, raw materials transportation to the manufacturing site, and the manufacturing of the product.
