Soprema Sopratherm XR4110 2400x1200x110mm

SOPRATHERM XR4000 (previously Celotex XRA4000) is an easy to install polyisocyanurate (PIR) insulation board with thermal performance, featuring a low emissivity foil facing. Available in thicknesses from 110mm to 200mm, it can be considered for roof, wall and floor applications.

  • Thermal Performance - Good thermal performance with a thermal conductivity of 0.022 W/m.K, reducing the thickness of insulation required to hit the target U-value.
  • Low emissivity Foil Facing - Provides improved thermal performance in sealed cavity air spaces, improving the achievable U-value.
  • Easy to Install - SOPREMA boards are light and rigid assisting with ease of transportation, handling and fitting.
  • BBA Certified - SOPRATHERM XR4000 has been assessed by the BBA as fit for use in defined roof, wall and floor applications if installed, used and maintained as set out in the certificate. Please read the BBA certification page for full details and restrictions.

SOPRATHERM XR4000 should not be used in the external walls of buildings over 11 metres in height. Recent changes to Building Regulations mean that only non-combustible insulation or insulation of limited combustibility should be used in buildings of that height.
