Guardian Glass has published six new Environmental Product Declarations (EPDs) for its flat, unprocessed, sputter (vacuum) coated and laminated glass products produced in Europe.
The six EPDs cover the following products:
- Guardian NEX 6 lower carbon glass;
- Guardian NEX 9 lower carbon glass;
- Guardian UltraClear low-iron float glass;
- Guardian ExtraClear float glass;
- Guardian LamiGlass and Guardian Bird1st Lami laminated glass product ranges; and
- Coated glass, including SunGuard, ClimaGuard and Guardian Sun products.
“By publishing EPDs, we support architects and designers who strive to understand the environmental impacts of the buildings they design through the products they specify,” says Jonathan Brunette, ESG and Certification manager. “The goal is to give them the information they need to calculate their building’s Whole Life Carbon emissions and make informed decisions.”
Guardian Glass officials say 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 of 9.64 kg CO2eq/m2 for 4 mm glass. A new EPD for Guardian UltraClear low-iron float glass produced at the Guardian Glass Bascharage, Luxembourg, plant is expected in mid-2025.
Officials add that 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.
Brunette explains that the EPD data is “helpful for companies working to attain their carbon emissions reduction objectives, whether these targets are voluntary or driven by local regulations such as the Building Whole Life Carbon regulations that are in effect across several countries in Europe, including Denmark, Sweden, France and The Netherlands. The data can also help achieve credits in building environmental certification assessment methods such as LEED or BREEAM.”
Guardian Glass also added a new feature to its Performance Calculator tool, which allows glass processors and specifiers to estimate the embodied carbon equivalent for various glazing combinations.
