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 or 4 ft × 8 ft sizes.

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 preventing any uncontrolled movement of air through the assemblies.

  • Up to 70% recycled material for the entire product line
