Ravatherm™ XPS X has been formulated with the addition of infra-red ‘blockers’ or particles which are finely dispersed and incorporated into the extruded cell walls. The particles scatter and reflect heat radiation resulting in reduced heat transfer during winter to keep a building warm, as well as in summer to keep it cool. Designed specifically for roofing applications.

Ravatherm™ Attributes:

  • Up to 11% better insulation performance than other CO2 blown XPS foams
  • Flame retarded, enhancing safety and protection on construction sites - free of HBCD (bio persistent) fire retardants
  • Proven features - durability, reliability and strength
  • Incorporates infra-red ‘blockers’ which improve thermal resistance by scattering and reflecting heat radiation
