160mm Soprema SOPRAXPS 700 SL ES XPS Board

The 160mm Soprema SOPRAXPS 700 SL ES is a rigid extruded polystyrene (XPS) insulation board engineered for demanding UK construction applications requiring superior thermal performance and durability. Manufactured using environmentally responsible CO₂ technology, this closed-cell XPS board delivers exceptional resistance to moisture and sustained thermal efficiency even in demanding environments.

Ideal for structural floors, basements, car parks, and inverted roofs, the 160mm Soprema XPS board achieves a minimum compressive strength of ≥700 kPa, enabling 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 reliable interlocking, minimises thermal bridging, and streamlines the installation process. Fully CE marked in accordance with BS EN 13164 and compatible with SOPREMA waterproofing systems, it satisfies rigorous UK and European construction requirements for dependability and performance.

Enhance your construction projects with 160mm Soprema SOPRAXPS 700 XPS insulation, built for load-bearing capability, thermal efficiency, and long-term reliability.
