The extremely selective solar control product family COOL-LITE® XTREME is now available on ORAÉ® substrate, the new low carbon glass of Saint-Gobain Glass.

With ORAÉ®, Saint-Gobain Glass has achieved a landmark technical breakthrough enabling it to offer the first glass with the lowest embodied carbon on the façade market thanks to a substantial R&D effort and the excellence of our industrial teams. This innovation will help to significantly reduce the carbon footprint of construction and accelerate the development of the circular economy.

Intended for use in the glazed parts of a facade, COOL-LITE® XTREME ORAÉ® is a perfect response to the stricter sustainability requirements of the building industry without any compromise on technical or aesthetic performance.

SUSTAINABILITY

COOL-LITE® XTREME ORAÉ® provides the best of both embodied and operational carbon levels, thanks to:

  • The exceptionally low carbon footprint of ORAÉ®, produced by combining high recycled glass content (around 70% of cullet, of which 55% of external cullet) and renewable energy. As a result, the new product offers the lowest carbon footprint on the market with a reduction of around 40% compared to our regular product.
  • The excellent energy performances of the COOL-LITE® XTREME coatings, which already drastically reduce carbon emissions generated by energy consumption, when using the building thanks to its high performance in terms of daylight intake, solar control and thermal insulation.

AESTHETICS

ORAÉ® is offering exactly the same aesthetics than the regular clear float glass PLANICLEAR®.

Combined with COOL-LITE® XTREME, the low external reflection as well as the extremely colour-neutral external appearance creates an excellent combination of function and aesthetics.

RANGE

COOL-LITE® XTREME ORAÉ® is available in standard sizes and thicknesses (4, 6, 8 and 10mm).

In complementarity to COOL-LITE® XTREME ORAÉ® assembled in double or triple glazing, the uncoated ORAÉ® as well as our low-e PLANITHERM® ORAÉ® and ECLAZ® ORAÉ® are also available for the counter panes.

REFERENCE PROJECTS

As an early demonstration of the market’s enthusiasm, three major real estate partners, Bouygues Immobilier, Icade Santé and Nexity, have already committed to use low carbon COOL-LITE® XTREME glass in their projects:

  • Bouygues Immobilier will implement it on its office building operation Kalifornia (Hauts-de-Seine, France)
  • Icade Santé will install it on the Elsan Group Polyclinique du Parc in Caen (Calvados, France) 
  • Nexity will use it on the Carré Invalides rehabilitation (Paris, France).

PERFORMANCES

COOL-LITE® XTREME ORAÉ® provides the same performances and quality as COOL-LITE® XTREME PLANICLEAR®, with a much lower carbon footprint.

The new ORAÉ® substrate has an estimated carbon footprint of only 7 kg CO2 eq/m2 (for a 4mm substrate), bringing a reduction of the carbon footprint around 40% compared to our European standard product PLANICLEAR®.

Coated, processed and assembled in insulated glazing unit, the reduction is then around 25% to 30%.

 
  1. According to EN673
  2. According to EN410
  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 will be documented through third party-verified environmental product declarations – EPDs (or FDES in France) – which are currently under development and scheduled for availability in early 2023. Calculation of GWP with ORAÉ® will be available on www.calumenlive.com early 2023, after the publication of the verified EPD.
  4. Global Warming Potential (GWP A1-A3 Stages) values with PLANICLEAR® are calculations made with CalumenLive 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.calumenlive.com.
