• Free of HBCD (bio persistent) fire retardants
  • Low thermal conductivity - minimising the board thickness needed to achieve a specific U-value, thus allowing the designer greater flexibility
  • High compressive strength - in load-bearing applications, the closed cell structure gives the foam greater rigidity and makes it highly resistant to compression
  • Low water absorption - Ravatherm X-Energy XPS ™ SL has natural resistance to rain, snow, frost and water vapour which makes it an exceptionally stable material, which retains its initial insulation performance and physical integrity in exposed conditions over the very long term. It was this unusual property that made the inverted warm flat roof concept possible, an idea pioneered by Ravago Building Solutions
  • User-friendliness - Ravatherm X-Energy XPS™ SL is easily worked with normal hand tools
  • Hygiene - Ravatherm X-Energy XPS ™ SL boards have low susceptibility to rot, meaning mould or fungal growth is minimised. They are clean, odourless and free from irritating dust.
