Soprema Sopratherm CW4100 1200x450x100mm

SOPRATHERM CW4000 (previously Celotex CW4000) is an easy to install polyisocyanurate (PIR) thermal insulation board, featuring a low emissivity foil facing. Available in thicknesses from 40mm to 100mm, it is suitable for use in partial fill cavity wall 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 - The boards are light and rigid assisting with ease of transportation, handling and fitting. They are sized to fit standard wall tie spacing for ease of installation
  • BBA Certified - SOPRATHERM CW4000 has been assessed by the BBA as fit for use in defined partial fill cavity wall applications if installed, used and maintained as set out in the certificate. Please read the BBA certification page for full details and restrictions.

When using SOPRATHERM CW4000, you need to satisfy yourself that use of the product meets all relevant national Building Regulations and guidance as well as local, national and other applicable standards relevant for your construction or application, including requirements in relation to fire and applicable height restrictions.
