Soprema Sopratherm TB4040 2400x1200x40mm

SOPRATHERM TB4000 (previously Celotex TB4000) is an easy to install polyisocyanurate (PIR) thermal insulation board, featuring a low emissivity foil facing. Available in thicknesses from 20mm to 40mm, it can be considered for floor, wall and roof 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 TB4000 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.
