An Ingredient for Climate Innovation

99.92% less GHG emissions than its previous formula

The SOPRA-XPS line of extruded polystyrene insulation panels is evolving for the better by being more environmentally sustainable. Get the power to reduce greenhouse gas emissions (GHG) from products used in the construction of your building by offering a low Global Warming Potential (GWP) solution of 1.


With Our SOPRA-XPS That Emits 99.92% Less GHGs Than the Old Formula

The new formula of the SOPRA-XPS product line mainly replaces the use of HFC-134a and CO2 with a Global Warming Potential (GWP) of 1,300 with a formula made of HFO and CO2 with a GWP of 1. This represents a reduction of the GWP of the products of at least 99.92% compared to the previous formula.

See the impact of a low carbon footprint architecture:

For a hypothetical case of a 20,000 sq. ft commercial building, the use of 1,870 panels with the previous formula would produce an industry average of 63.97 Mt CO2 eq. compared to 0.08 Mt CO2 eq. for SOPRA-XPS panels with the new formula.
Read this article to learn more about how we reduced the carbon footprint of the SOPRA-XPS line of insulation products, a new generation of products that combine performance and respect for the environment.


For SOPREMA Canada, October 2020 marked the culmination of major changes to its SOPRA-XPS insulation product line. These changes have made it possible to considerably reduce greenhouse gas (GHG) emissions associated with the manufacturing process (Scope 1) and the product (Scope 3).

Overall, for SOPREMA, the reduction in GWP makes it possible to decrease total GHG emissions by 98.71%, which represents more than 110,340 Mt CO2 eq. avoided.

The new generation of SOPRA-XPS demonstrates SOPREMA Canada’s commitment to the fight against climate change, namely by reducing its GHG emissions and improving the carbon footprint of its building products.

For SOPREMA, being involved in sustainable development by investing in innovation is a necessity. Our transition to Solstice GBA for XPS production and products is just one example of our commitment to adopt materials and good practices that are synonymous with value creation to move society forward and guarantee the sustainability of our planet.

The evolution of the SOPRA-XPS line opens the way to a whole new generation of eco-friendlier products, both in terms of supply and the end of their useful life. While keeping the same properties regarding the performance of the products, these major changes in the formula specifically relate to the carbon footprint and recycled content of the line.

SOPRA-XPS is the product line with the highest recycled content on the market, an outstanding reduction at the source with 70% recycled and recovered content.
The new formula of the extruded polystyrene (XPS) foam product line offers a 99.92% reduction of the Global Warming Potential (GWP) while maintaining product performance.


SOPREMA has chosen Honeywell’s low Global Warming Potential Solstice® Gas Blowing Agent (GBA) for production of the SOPRA-XPS product line. SOPREMA replaced HFC-134a with Solstice GBA in its entire SOPRA-XPS panel production at its manufacturing site in Sherbrooke, Québec.

By replacing hydrofluorocarbon (HFC) blowing agents with low-GWP solutions, SOPREMA meets changing environmental regulations calling for a global phase down of HFCs. Solstice GBA provides energy efficiency performance similar to that of HFC-134a, and superior to that of carbon dioxide. Based on hydrofluoroolefin (HFO) technology, Solstice GBA has a GWP of less than 1 (more than 99.9% lower than HFCs and lower than carbon dioxide).

SOPRA-XPS meets performance requirements while staying ahead of changing environmental regulations requiring a transition to low-GWP blowing agents. With proven reliable performance, thanks to the Solstice GBA, SOPRA-XPS offers the most innovative, sustainable, and safe solutions for insulation in its category!
