Improved Transparency for the SOPRA-XPS Product Line Thanks to Our New EPD

Our line of SOPRA-XPS extruded polystyrene panels is evolving by becoming more environmentally friendly. Now you can reduce greenhouse gas (GHG) emissions from materials employed in the construction of your buildings with SOPRA-XPS, which uses a blowing agent with a global warming potential (GWP) of less than 1.

CONSULT SOPRA-XPS EPD

Thanks to our environmental product declaration (EPD)1 , it is now easier to discover the environmental impact of SOPRA-XPS. This product also has the lowest carbon impact in its class on the market. Read our EPD that proves it!

This EPD shows the results of the life cycle assessment (LCA) of SOPRA-XPS insulation, including the stages of raw material supply, manufacturing, transportation, installation, use, and end of life (cradle to grave).

Why Is the Environmental Indicator for CO2 So Important?

Global warming is well-known worldwide and its effects (floods, forest fires, heat waves, storms, etc.) are getting more intense and frequent. International climate conferences have initiated many discussions and negotiations between countries on targets and objectives for reducing greenhouse gases. It is therefore now a global issue.

Global warming is largely due to the greenhouse effect, a phenomenon caused by the accumulation of gases in the atmosphere that form a barrier and trap solar radiation as well as heat. Greenhouse gases include CO2 and methane, to name just two.

Each gas has its own impact on global warming (known as global warming potential or GWP), which is expressed in relation to the impact of CO2. Methane has a GWP of 25, which means that for the same quantity of gas, the impact on global warming of methane is 25 times as high as that of CO2.

Dare to compare to make informed decisions

January 1, 2021 marked the entry into force of new regulations from Environment and Climate Change Canada (ECCC) which govern the use of halocarbons as blowing agents in plastic foams and set the maximum limit of their global warming potential (GWP) to 150.

Unfortunately, not all manufacturers comply with this new regulation. Some have also obtained exemptions from the Canadian government to circumvent it, and thus sell insulation with HFC emissions up to five times higher than the limit allowed. A reduced GWP does not necessarily mean that it is under 150. Accept no compromise for our planet: demand high standards now! Construction professionals who want to make a difference will understand the difference.

Base your actions on facts and ask manufacturers to provide the technical and environmental data related to their products. To help you make informed decisions, read the list of manufacturers that obtained a permit:

Reducing a building's carbon footprint with SOPRA-XPS

The construction industry is exerting more and more pressure on the environment due to the consumption of raw materials and the waste of residual materials. Concerned about this issue, SOPREMA has set up a new formula for its SOPRA-XPS line which replaces the HFC-134a blowing agent, having a GWP of 1,300, with a hydrofluoroolefin (HFO) blowing agent having a GWP of less than 1.

The new generation of SOPRA-XPS clearly demonstrates SOPREMA’s commitment to the fight against climate change, in particular by reducing greenhouse gas emissions and improving the carbon footprint of its products used in buildings.

SOPRA-XPS is the product line with the highest recycled content on the market, i.e. 70%6. This is a form of reduction at source by promoting recycling.

ASSESSMENT OF LIFE CYCLE IMPACT CATEGORIES

The Various Environmental Issues Assessed in the EPD

It should be noted that the life cycle impact assessment does not predict actual impacts, exceeding thresholds, safety margins, or risks associated with the targeted product. The results nevertheless provide a relevant theoretical overview to better understand the environmental impact of a product. In this case, six categories of life cycle impact assessment are addressed in the EPD, which is recognized as a Type III environmental declaration produced in accordance with EN 15804, ISO 14025, and ISO 21930 standards. With the advancement of scientific research, impact assessment methods are being refined and other impact categories are being developed. At this time, it is not recommended to use other impact categories for comparison purposes.
