Description

100mm Soprema SOPRAXPS 300 SL FN is a premium rigid extruded polystyrene (XPS) insulation board engineered for demanding UK construction projects requiring superior compressive strength and water resistance. Delivering 300kPa compressive strength, it provides robust thermal insulation performance under substantial loading conditions.

Manufactured to 1250mm x 600mm x 100mm dimensions, this Soprema XPS board suits diverse commercial, industrial and specialist applications. Common uses encompass solid ground floors, underground structures, basements, car parks, swimming pools, refrigerated storage, and both flat and pitched roof systems.

In comparison to conventional EPS (expanded polystyrene) insulation, which typically achieves around 70kPa compressive strength, Soprema SOPRAXPS 300 SL FN provides substantially superior load-bearing capability. This positions it as the preferred insulation board for high-footfall zones and structural applications demanding proven strength and performance.

Key Features

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

The rebated edge design enhances thermal continuity and minimises thermal bridging. Its closed-cell XPS composition delivers exceptional water, moisture and frost resistance, maintaining consistent thermal performance in wet or subterranean environments. This 100mm Soprema XPS board is manufactured using climate-friendly CO₂ technology, supporting environmentally responsible UK construction.

For inverted roof applications, including zero-fall and flat roofs, 100mm Soprema SOPRAXPS must be installed with ballast to guarantee stability and sustained performance.

Engineered to satisfy current UK building regulations, 100mm Soprema SOPRAXPS 300 SL FN insulation boards deliver exceptional strength, longevity and thermal efficiency for diverse construction and civil engineering applications.
