140mm Soprema SOPRAXPS 700 SL XPS Board

The 140mm Soprema SOPRAXPS 700 SL ES is a rigid extruded polystyrene (XPS) insulation board engineered for demanding UK construction applications requiring superior thermal performance and structural resilience. Manufactured with environmentally conscious CO₂ technology, this closed-cell XPS board delivers exceptional water resistance and sustained thermal efficiency even in harsh environments.

Ideal for structural floors, basement installations, car parks, and inverted roof systems, the 140mm Soprema XPS board achieves a minimum compressive strength of ≥700 kPa, allowing it to support substantial loads whilst preserving structural integrity throughout its service life.

With a smooth finish and shiplap (SL) edge configuration, this XPS insulation board enables secure interlocking between boards, minimises thermal bridging, and streamlines the installation process. Certified to BS EN 13164 and fully compatible with SOPREMA waterproofing solutions, it satisfies rigorous UK and European building standards.

Enhance your construction projects with 140mm Soprema SOPRAXPS 700 XPS insulation, delivering proven strength, thermal efficiency, and long-term durability.
