Soprema SOPRAXPS 500 SL ES 180mm XPS Board

180mm Soprema Sopraxps 500 SL ES is a rigid extruded polystyrene (XPS) thermal insulation board designed for UK construction applications requiring high compressive strength and extended durability. Produced using climate-friendly CO₂ technology, this 180mm board provides outstanding thermal efficiency and moisture resistance in challenging conditions.

Suited to structural floors, car parks, basements and inverted roofs, the 180mm Soprema SOPRAXPS 500 SL ES handles high load-bearing requirements with a minimum compressive strength of ≥500 kPa, preserving structural integrity under load and delivering consistent performance throughout its lifespan.

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