Kelyfos Rooftile

Kelyfos Rooftile is a composite thermal insulation tile (dimensions 30x60 cm) comprising a thermal insulation layer of extruded polystyrene (Xenergy) and a surface finish of a white protective layer of cement mortar of 2cm thickness.

The extrusion process gives Xenergy its distinctive closed cell structure and the following physical properties:

  • Low modulus of thermal conductivity
  • Low water absorption
  • High compressive strength

Also Kelyfos Rooftile is designed to offer the greatest possible advantage in inverted insulation of flat roofs, as its edges have a tongue and groove profile that ensures the extinction of thermal bridges and the excellent walkability of the final surface.

Advantages

  1. Reducing thermal bridges, due to TG configuration
  2. Protection of structure from weathering
  3. Protection of the water insulation layer from ageing
  4. Ease and speed of installation
  5. Lightweight (46kg/m²) appropriate for flat roofs requiring light weight surface covering
  6. Possibility to re-use the material in cases of extensions or new floors addition.
