Kelyfos Rooftile is a composite thermal insulation tile (dimensions 30x60 cm) comprising a thermal insulation layer of extruded polystyrene (Ravatherm XPS X) and a surface finish of a white protective layer of cement mortar of 2cm thickness.
The extrusion process gives Ravatherm XPS X its distinctive closed cell structure and the following physical properties:
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.
