ORAÉ® – Fully EPD Verified, Low-Carbon Glass

As the world’s first EPD-verified low-carbon glass, ORAÉ® has been developed with a sustainability-first perspective, reducing carbon emissions, and helping to advance the circular economy without compromising on aesthetics or technical standards.

Achieving a remarkably low carbon footprint of 6.64 kg of CO2 eq./m2 for a 4 mm glass, as an energy efficient glass, ORAÉ® owes its eco-friendly credentials to a robust combination of factors. Notably, it incorporates an impressive 64% recycled content alongside the utilisation of renewable electricity sources.

The COOL-LITE® XTREME ORAÉ® stands out for its dual excellence in both embodied and operational carbon levels, owing to two key factors:

  • ORAÉ® achieves its exceptionally low carbon footprint through a strategic blend of high recycled glass content, comprising approximately 70% of cullet, including 55% external cullet, and the utilisation of renewable energy sources. This innovative approach favourably positions ORAÉ® in the market, as it boasts a remarkable 40% reduction in carbon footprint compared to our standard products.
  • The COOL-LITE® XTREME coatings contribute significantly to energy efficiency, further minimising carbon emissions generated by energy consumption during the building’s usage. With its outstanding performance in terms of daylight intake, solar control, and thermal insulation, COOL-LITE® XTREME® enhances the overall sustainability profile of ORAÉ®, offering a comprehensive solution for sustainability conscious projects.

ORAÉ® for Balustrades and Balconies
ORAÉ® low carbon glass is an ideal choice for both internal and external balustrades and balcony applications, delivering high levels of sustainability, clarity, and performance. Its low-carbon composition makes it the perfect solution for projects striving to meet ambitious environmental targets without compromising on design aesthetics. Manufactured in the UK using renewable energy and high levels of recycled content, each pane contributes to lowering embodied carbon while supporting certifications such as BREEAM and LEED. ORAÉ®’s – visual transparency enhances natural light transmission – essential for open, contemporary designs – allowing architects and specifiers to create striking, light-filled spaces that combine beauty, safety, and sustainability. For these applications, ORAÉ® should be specified as laminated toughened glass to ensure impact resistance and continued protection in the event of breakage, in line with relevant safety standards

3 Global Warming Potential (GWP) A1-A3 Stages: The GWP values with ORAÉ®, are estimations based on our Life Cycle Assessment model. Data were collected during the 4 ORAÉ® campaigns made in 2022. The detailed environmental data is documented through third party-verified environmental product declarations – EPDs – which are available at www.calumen.com.
4 Global Warming Potential (GWP A1-A3 Stages) values with PLANICLEAR® are calculations made with Calumen regarding the composition computed based on the standard EN 15804+A2. Estimations
based on the Life Cycle Analysis (LCA) of our products. Only complete Environmental Product Declaration (EPD) can be verified by an external third party. GWP calculations of any glazing configuration with PLANICLEAR® can already be made on www.calumen.com.
