Soprema SOPRAXPS 500 SL ES 80mm XPS Board

80mm Soprema SOPRAXPS 500 SL ES is a rigid extruded polystyrene (XPS) thermal insulation board designed for UK construction applications where high compressive strength and durability are critical. Manufactured with climate-friendly CO₂ technology, this 80mm board provides excellent thermal efficiency and moisture resistance in challenging conditions.

Suited to structural floors, car parks, basements and inverted roofs, the 80mm Soprema SOPRAXPS 500 SL ES withstands high load-bearing demands with a minimum compressive strength of ≥500 kPa, ensuring structural integrity and reliable long-term performance.

This XPS insulation board features a smooth finish with shiplap (SL) edge profile for secure interlocking joints, minimising thermal bridging and streamlining the installation process. Certified to BS EN 13164 with CE marking and fully compatible with SOPREMA waterproofing systems, it satisfies UK and European standards for performance and longevity.
