Guardian Glass has published six new Environmental Product Declarations for its flat unprocessed glass, sputter (vacuum) coated glass, and laminated glass products produced in Europe. One of the new EPDs covers Guardian ExtraClear float glass.
The six EPDs cover the following products:
- Guardian Nexa 6 lower carbon glass
- Guardian Nexa 9 lower carbon glass
- Guardian UltraClear low-iron float glass
- Guardian ExtraClear float glass
- Guardian LamiGlass and Guardian Bird1st Lami laminated glass product ranges
- Coated glass, including (but not limited to) SunGuard, ClimaGuard and Guardian Sun products.
The new unprocessed flat glass EPD, which covers Guardian ExtraClear standard float glass produced in Europe, has a cradle-to-gate (A1-A3) embodied carbon value (2) of 9.64 kilograms carbon dioxide equivalent emitted per square meter (CO2eq/m2) for 4 millimeter glass. A new EPD for Guardian UltraClear low-iron float glass—produced at the Guardian Glass Bascharage, Luxembourg plant, in Guardian Glass’ most energy-efficient furnace—is anticipated to be available in mid 2025.
EPDs are also now available for the new lower carbon glass range of products. Guardian Nexa 6 and Guardian Nexa 9 each have their own EPD, with embodied carbon values for 4 mm glass of 6.38 kg CO2eq/m2 and 8.58 kg CO2eq/m2, respectively. Compared to the average European float glass dataset, this represents a reduction in embodied carbon of more than 40% for Guardian Nexa 6 and 20% for Guardian Nexa 9.
