Following successful pilot production runs, Guardian Glass is introducing a lower-carbon float glass to the European market. The new Guardian Nexa™ can also be used as a base or laminated glass for Guardian high performance products, including the Guardian SunGuard™ and Guardian ClimaGuard™ ranges of coated glass products.
Gardian Nexa glass, developed through research and development, technical innovation and manufacturing expertise, can be used in a wide range of building façade applications and will help to reduce the embodied carbon of the built environment. When compared to Guardian Glass’ standard float glass production, the benefits of Guardian Nexa glass include:
- Reduced embodied carbon by more than 30 percent to approximately 7.0 kg CO2e/m2 for 4 millimetre float glass
- Higher cullet content – from both internal and external sources
- No compromise on performance and aesthetics, similar to Guardian ExtraClear™ float glass
Environmental Stewardship
Guardian Glass strives to improve both the environmental performance and effectiveness of its manufacturing processes and of its products, while consuming fewer resources. This involves considering each stage of the process, including the sourcing of raw materials and the efficiency of our furnaces.
Guus Boekhoudt, Guardian Glass Executive Vice President, said, “This is a significant accomplishment by our R&D and operations teams, achieved through a combination of ongoing innovation in manufacturing processes and the optimization of cullet use. It reflects our dedication to our Environmental Stewardship priorities, including improving energy efficiency and air emissions, and managing resources responsibly.”
Environmental Product Declaration availability
Detailed environmental data on Guardian Nexa will be documented through an Environmental Product Declaration (EPD). This is currently under development and is expected to be available in Q2 2024. Since 2021, the scope of the EPDs for Guardian Glass products in Europe has been widened to consider CO2 emissions generated from production processes, increasing the level of transparency provided to customers.
