In particular, Ravatherm XPS S has:

  • Very low f thermal conductivity (for material thicknesses from 20-50 mm λ = 0.030 W / mK and from 60-120 mm λ = 0.031 W / mK)
  • High resistance to compression
  • Low water absorption
  • Ease of use
  • Hygiene


Ravatherm XPS S covers the range of applications of the well-known blue thermal insulation  boards and is available in various thicknesses and types, designed to meet the performance requirements of specialized applications. More specifically:



  • Thermal insulation of simple and planted roofs
  • Thermal insulation of inclined roofs
  • Thermal insulation of concrete elements
  • Thermal insulation of masonry
  • External Thermal Insulation
  • Thermal insulation of basements
  • Thermal insulation of refrigerators



* Ravago Building Solutions (RBS) by incorporating all the brand names of extruded polystyrene products under the new brand name "Ravatherm XPS", expands its potential and strengthens its identity on a pan-European level.
