Celotex SL4000

Celotex SL4000 is a high performance thermal insulation board combining premium performance PIR insulation bonded to 6mm calcium silicate. SL4000 is specifically targeted at concrete soffit floor applications.

SL4000 is manufactured from rigid polyisocyanurate (PIR) using a blend of blowing agents that have a zero ozone depletion potential (ODP) and low global warming potential (GWP).

With Celotex SL4000, you are specifying an insulation board that:

  • Utilises the unrivalled insulation properties of premium Celotex FR4000 with calcium silicate providing additional fire performance
  • Reduces installation times due to the insulation and calcium silicate being supplied as one product
  • Delivers greater impact resistance compared to exposed insulation systems
  • Provides a decorative finish with no need for on-site decorating
  • Is a lighter weight solution that other insulation options
  • Offers enhanced thermal performance and even lower U-values
  • Provides long term energy savings for buildings

Applications
Celotex SL4000 is specifically targeted at concrete soffit floor applications such as underground car parks situated beneath habitable buildings e.g. offices or residential apartments
