SOPREMA SOPRA-XPS 60 Extruded Polystyrene Insulation Board, 2 in. or 3 in. x 2 ft. x 8 ft., 60 psi
Soprema SOPRA-XPS 60 is a rigid extruded polystyrene closed-cell foam insulation board rated at 60 psi, supplied in 2 ft. x 8 ft. boards in 2 in. and 3 in. thicknesses. It is used under slabs, in inverted protected-membrane roofing, parking decks, plaza decks and civil engineering applications.
Key Features:
- Closed-cell XPS: Rigid insulation board made of extruded polystyrene closed-cell foam.
- 60 psi compressive strength: Rated for 60 psi applications such as under slabs and traffic decks.
- Two thicknesses: Offered in 2 in. and 3 in. x 2 ft. x 8 ft. board sizes.
- Inverted roof ready: Used in protected-membrane (inverted) roofing systems over the membrane.
- Below-grade capable: Suited for SOPREMA foundation systems under slabs and civil engineering work.

Expert Verdict — Reviewed by the SuperArbor Pro Desk
SOPRA-XPS 60 balances thermal performance with the compressive strength needed for plaza and parking deck assemblies. In inverted roof designs, board thickness drives the R-value, so the 3 in. board suits higher thermal targets, while the 2 in. pack offers an economical option for standard under-slab work. Keep boards flat and protected from UV and jobsite traffic before installation.
Follow the project specification and roof-safety plan; protect boards from damage and use care when cutting XPS insulation.
Order Soprema SOPRA-XPS 60 insulation boards for your inverted roof or under-slab project.
