SOPRA-XPS.

EXTRUDED POLYSTYRENE
INSULATION PANELS

Versatile and robust, SOPRA-XPS is designed to perform in all applications.

OVERVIEW OF SOPRA-XPS

Made of cellular foam, SOPRA-XPS extruded polystyrene thermal insulation panels are primarily used as thermal insulation for foundations, walls, and inverted roof systems, including plaza decks, green roofs, and parking decks.

WHAT MAKES SOPRA-XPS UNIQUE

Thanks to the density of their closed-cell composition, SOPRA-XPS panels have exceptional resistance to water and water vapour and they prevent voids in the insulation. This prevents any uncontrolled movement of air through the assemblies.

RESISTANT IN ALL OF ITS ASPECTS

In addition to being resistant to water and water vapour, SOPRA-XPS panels are versatile and capable of withstanding extreme temperature changes and freeze-thaw cycles without permanent damage. Moreover, even when exposed to moisture, SOPRA-XPS resists mould and bacteria.

TOUGHNESS AND SUSTAINABILITY

Rigid and non-friable, SOPRA-XPS panels are suitable for a variety of applications. Sharp and clean cuts are easy to make and do not generate dust. Lightweight and easy to install, SOPRA-XPS panels are offered with various compressive strengths to meet all needs. Moreover, they provide one of the highest compressive strengths on the market, whether against heavy or dynamic loads.

CONSTANT PERFORMANCE

SOPRA-XPS panels are compliant with the CAN ULC S701.1 standard thanks to the following four features: good compressive strength, high R-value (R-5/inch), dimensional stability and very low water absorption. Moreover, they provide a constant long-term R-value (LTTR) of R-5 per inch, even at low temperatures. They maintain their thermal and mechanical performance throughout the life of the building.

VARIETY OF THE OFFERING

SOPREMA offers high-quality extruded polystyrene thermal insulation panels. 
SOPRA-XPS panels are available with either straight or shiplap edges, and in
2 ft × 8 ft and 4 ft × 8 ft sizes.

SOPRA-XPS 20

SOPRA-XPS 20 panels with shiplap edges are designed for the insulation of above-grade exterior walls.

SOPRA-XPS 20 panels with grooved edges are perfect for the insulation of above-grade exterior walls and on the inside of foundation walls. The grooved edges are specially designed to accommodate 1 × 3 inch wood furring.

SOPRA-XPS 25 CW

Perfect for cavity wall insulation. Thanks to their practical dimensions, they fit perfectly between the rows of wall ties.

SOPRA-XPS 30

Designed for the insulation of exterior foundation walls and under foundation slabs.

SOPRA-XPS 35

Ideal for the insulation of new or refurbished inverted roofs to improve their thermal resistance.

SOPRA-XPS 40, 60 et 100

Designed for heavy-duty applications requiring high-density insulation. Their applications include inverted roofs, such as green roofs and plaza decks. They can also be used under foundation slabs that support dead or very heavy live loads.
