KELYFOS ROOFTILE
XPS roof insulation over existing screeds (kontrabejt)
Kelyfos Rooftile is a composite thermal insulation tile (dimensions 60 x 30cm) 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:
- 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.
