160mm Soprema SOPRAXPS 500 SL ES XPS Board

160mm Soprema SOPRAXPS 500 SL ES is a rigid extruded polystyrene (XPS) thermal insulation board designed for UK construction applications demanding superior compressive strength and extended durability. Built with climate-friendly CO₂ technology, this 160mm board provides outstanding thermal efficiency and moisture protection in challenging conditions.

Suited to structural floors, car parks, basements and inverted roofs, the 160mm Soprema SOPRAXPS 500 SL ES handles high load-bearing requirements with a minimum compressive strength of ≥500 kPa, ensuring structural integrity under sustained pressure and reliable long-term performance.

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 with CE marking to BS EN 13164 and compatible with SOPREMA waterproofing systems, it complies with UK and European standards for quality and longevity.
