Soprema bought Celotex from Saint-Gobain and rebranded the range, so the Celotex XR4000 boards you know are now Sopratherm XR4000 (sometimes searched for as Sopretherm or Supertherm). It is a thicker PIR board for pitched roofs, floors and walls where you need a low U-value from a single layer. The board has a PIR foam core with low-emissivity composite foil facings on both sides, a declared thermal conductivity of 0.022 W\/mK and, at 120mm, a thermal resistance of 5.45 m²K\/W according to Soprema's datasheet.
