The world’s first low-carbon glass ORAÉ® combined with the best in class coatings.

PRODUCT DESCRIPTION

With ORAÉ®, Saint-Gobain Glass has achieved a landmark technical breakthrough enabling it to offer the first glass with a low embodied carbon 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.

BENEFITS & APPLICATIONS

Combined with our best-in-class coatings,  ORAÉ® provides the best of both embodied and operational carbon levels, thanks to:
The low carbon footprint of ORAÉ® (6.64 kg of CO2 eq./m2 for a 4 mm glass), produced by combining high recycled glass content (64% according to ISO 14021:1999) and renewable electricity. 
The excellent energy performances of the COOL-LITE®, ECLAZ® LUMI and PLANITHERM® coating families.

ORAÉ® can be used for new buildings or renovation, residential or non-residential. ORAÉ® can replace standard clear glass of the same thickness, whatever the application:

  • Building envelope: insulating glazing for windows, facade elements or glass roofs.
  • Other external or internal applications (e.g., balustrades, doors, partitions...): upon request.

Cradle to Cradle Certified® version 4.0 certification

ORAÉ® is Cradle to Cradle Certified® Bronze. Cradle to Cradle Certified® V4.0 assesses products based on five rigorous categories: material health, product circularity, climate air & climate protection, water & soil stewardship, and social fairness. 

As part of achieving certification, it received a Platinum rating for Product circularity thanks to its high recycled glass content.

APPEARANCE

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

 

TECHNICAL INFORMATION

RANGE

ORAÉ® is available as:

  • Monolithic clear float glass (in 3, 4, 6, 8 and 10 mm)
  • Assembled in STADIP® or STADIP SILENCE® for safety or reinforced acoustic insulation
  • Combined with the highly selective solar control product families COOL-LITE® XTREME and COOL-LITE® SKN
  • Combined with COOL-LITE® ST for spandrels or double-skin façades.
  • Combined with summer comfort coatings of the product family PLANISTAR®
  • Combined with Low-e coatings of the product families ECLAZ® LUMI AND PLANITHERM®.

Please contact your local sales or specification teams to know the available offer in your country. 

DETAILED RANGE OF COATED ORAÉ®
 
Our coated ORAÉ® products are available in standard sizes and thicknesses (3, 4, 5, 6, 8 and 10 mm).
ORAÉ® is produced in 7 plants in Spain, France, Germany (2), UK, Italy and India.
They provide the same aesthetics, performances and quality as on PLANICLEAR®, with a much lower carbon footprint.
For double or triple glazing units, all panes should be made with ORAÉ® to minimize the carbon footprint.


COATED ORAÉ® FOR FAÇADE APPLICATIONS

 

COOL_LITE_LOGOS

Intended for use in the glazed parts of a façade (e.g., curtain wall, double skin façade, skylight...), COOL-LITE® ORAÉ® is a perfect response to the stricter sustainability requirements of the building industry without any compromise on technical or aesthetic performance.

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

  • The glass substrate ORAÉ®, with its low carbon footprint verified by an Environmental Product Declaration (EPD)
  • The excellent energy performances of the COOL-LITE® XTREME and COOL-LITE® SKN 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.

For opaque parts of buildings (spandrels) and double-skin façades, ORAÉ® can also be combined with COOL-LITE® ST for more flexibility, offering thus fully glazed facade with reduced carbon footprint.
 

COATED ORAÉ® FOR WINDOW APPLICATIONS
 

planistar& eclaz orae

For windows dedicated to non-residential or residential applications, ORAÉ® is available with a complete range of summer comfort or low-e coatings, offering at the same time:

  • Low embodied carbon footprint of the glass substrate ORAÉ®
  • High thermal performances of the products from the PLANISTAR® or ECLAZ® families for wiser energy consumption and a reduced operational carbon footprint.

 
As the windows offer is country defined, please contact your local sales team to confirm the low-e or summer comfort offer availability

PERFORMANCE

ORAÉ® provides the same performances and quality as PLANICLEAR®, with a lower carbon footprint.

According to its verified EPD:

  • The ORAÉ® substrate has a carbon footprint of only 6.64 kg CO2 eq./m2 (for a 4mm substrate),bringing a reduction of  42% compared to our European standard product PLANICLEAR® (publication of the EPD in April 2023).
  • The magnetron COOL-LITE® coatings on ORAÉ® have a carbon footprint of only 10.26 kg CO2 eq./m2 (for a 6 mm substrate), bringing a reduction of 43% compared to our European standard product magnetron coating on PLANICLEAR® (publication of the EPD in November 2023).
  • According to its verified EPD, coated ORAÉ® has a carbon footprint of only 10.71 kg CO2 eq./m2 (for a 6mm substrate), bringing a reduction of 43% compared to our European standard product coated PLANICLEAR®.

Coated, processed and assembled in insulated glazing unit, the carbon footprint reduction is then around 30% to 40%, depending on the exact IGU composition.

Oraé_Products_Schema
  1. According to EN673
  2. According to EN410
  3. Global Warming Potential (GWP A1-A3 stages) values with PLANICLEAR® and ORAÉ®, are calculations made with Calumen®  for each composition of insulated glazing unit (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®. Only complete EPD can be verified by an external third party.
  4. 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. 

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 has implemented it on its office building operation Kalifornia (Hauts-de-Seine, France)
Icade Santé has installed it on the Elsan Group Polyclinique du Parc in Caen (Calvados, France) 
Nexity has used it on the Carré Invalides rehabilitation (Paris, France)
NCC chose it for a new office project Habitat 7 (Gothenburg, Sweden)
