Soprema SOPRAXPS 700 SL ES 80mm XPS Board

The 80mm Soprema SOPRAXPS 700 SL ES is a rigid extruded polystyrene (XPS) insulation board engineered for demanding UK construction applications where thermal efficiency and structural performance are essential. Manufactured using CO₂ technology, this board delivers superior moisture resistance and sustained thermal properties in harsh environments.

Ideal for structural floors, basement applications, car parks, and inverted roof systems, the 80mm 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.

The smooth surface and shiplap (SL) edge profile facilitate secure interlocking between boards, minimise thermal bridging, and streamline the installation process. Fully CE marked to BS EN 13164 and compatible with SOPREMA waterproofing systems, this product satisfies rigorous UK and European building standards.

Specify 80mm Soprema SOPRAXPS 700 XPS insulation for projects demanding strength, thermal performance, and long-term durability.
