Guardian Glass has published Environmental Product Declarations (EPDs) for its glass products produced in North America.
Products covered include its range of float glass (clear, low-iron and tinted), sputter-coated glass (Guardian SunGuard architectural glass and Guardian ClimaGuard residential glass), wet coated glass, and heat-treated glass products.
Its North America unprocessed flat glass EPD has a cradle-to-gate (A1-A3) embodied carbon value of approximately 1102 kg CO2e/ton (TRACI 2.1 Method).
This new value is:
Approx. 23% lower than National Glass Association’s 2019 EPD value of 1430 kg CO2e/ton.
Approx. 24% lower than Guardian Glass’ 2018 EPD value of 1455 kg CO2e/ton.
The unprocessed flat glass value will help customers meet the top 20% limit in the US General Service Administration’s 'Low Embodied Carbon Material Standard'.
In parallel, Guardian Glass has introduced an additional feature to its current Performance Calculator tool, which allows users to calculate the embodied carbon for the glazing configurations they select.
This online tool (part of Glass Analytics) enables the modelling of the thermal and optical properties of glass substrates, coatings and interlayers.
The new Performance Calculator feature provides an estimate of the embodied carbon equivalent for a wide number of glazing combinations, as it is available for most float glass and sputter-coated glass products produced by Guardian Glass in North America, South America, Europe and Africa Middle East (AME).
Access to Glass Analytics and the embodied carbon calculator feature is available via the Resource Hub on the Guardian Glass website: guardianglass.com/resource-hub
