Description

SOPRATHERM PIR XR4000 – High-Performance PIR Thermal Insulation Board

SOPRATHERM is a premium polyisocyanurate (PIR) insulation board engineered for superior thermal performance and versatility across a wide range of construction applications. Previously known as Celotex XR4000, this rigid insulation solution combines excellent insulation efficiency with practical installation benefits to help meet modern building regulations and improve overall energy performance.

Key Features & Benefits

  • Excellent Thermal Efficiency: With a low thermal conductivity of 0.022 W/m·K, SOPRATHERM XR4000 PIR provides outstanding insulation performance, helping to achieve target U-values with reduced board thickness.

  • Low-Emissivity Foil Facing: Foil-faced on both sides to enhance thermal performance, particularly when used in sealed cavity air spaces.

  • Lightweight & Easy to Install: Rigid yet lightweight boards allow for easier handling, cutting and installation, helping to reduce labour time on site.

  • Certified Performance: Independently certified for use in defined roof, wall and floor applications when installed in accordance with technical guidance.
