Soprema SOPRAXPS 300 SL FN 260mm XPS Board

260mm Soprema SOPRAXPS 300 SL FN insulation board delivers high-performance rigid extruded polystyrene (XPS) thermal protection for demanding UK construction projects requiring robust compressive strength and superior moisture resistance. Offering 300kPa compressive strength, this board provides reliable, long-term thermal insulation for areas exposed to substantial structural loads.

Manufactured to 1250mm x 600mm x 260mm dimensions, Soprema XPS 300 SL suits diverse commercial, industrial and specialist applications. Common uses encompass solid floor systems, underground structures, basement spaces, vehicle parks, swimming pools, refrigerated storage, and both flat and sloped roof configurations.

In contrast to conventional EPS (expanded polystyrene) insulation, which typically achieves around 70kPa compressive strength, Soprema SOPRAXPS 300 SL FN delivers substantially superior load-bearing capacity. This positions it as an excellent choice for high-footfall zones and load-bearing applications where performance and durability matter most.

Key Features

• Moisture-Resistant
• Shiplap (SL) Edges
• High Compressive Strength
• Closed-Cell XPS Foam Core

The board incorporates a rebated edge profile that enhances thermal continuity and minimises thermal bridging. Its closed-cell XPS structure delivers excellent water, moisture and frost resistance, maintaining consistent thermal performance in wet or subterranean environments. This 260mm Soprema XPS insulation is manufactured using climate-friendly CO₂ technology, promoting sustainable construction methods across the UK.

For inverted roof applications, including zero-fall and flat roof systems, 260mm Soprema SOPRAXPS must be secured with ballast to guarantee stability and sustained performance.

Engineered to comply with current UK building standards, 260mm Soprema SOPRAXPS 300 SL FN insulation boards deliver exceptional load capacity, longevity and thermal performance across numerous construction and civil engineering applications.
