Performances
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. 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.



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 (64% according to ISO 14021:1999) and renewable electricity. As a result, the new product offers the lowest carbon footprint on the market with a reduction of 42% 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.

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.

Applications

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.


REFERENCE PROJECTS

As an early demonstration of the market’s enthusiasm, four major real estate partners, Bouygues Immobilier, Icade Santé, Nexity and NCC 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)

• NCC chose it for a new office project Habitat 7 (Gothenburg, Sweden)



Product 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.

Performances

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


According to the verified EPD published in april 2023, the ORAÉ® substrate has a carbon footprint of only 6.64 kg CO2 eq./m2 (for a 4mm substrate), a reduction of 42% compared to our European standard product PLANICLEAR®.


Coated, processed and assembled in insulated glazing unit, the reduction is then around 30% to 40%.


According to EN673

According to EN410

Global Warming Potential (GWP A1-A3 stages) values with PLANICLEAR® and ORAÉ® are calculations made with Calumen® for each composition of IGU on the basis of the standard EN 15804+A2. Detailed environmental data are documented in the available Environmental Product Declarations (EPD) of PLANICLEAR® and ORAÉ®.

All panes of the DGU with the same substrate; first pane respectively annealed or tempered (II) with the same glass compositions; counter panes always annealed.
