Extruded polystyrene (XPS) thermal insulation designed for high loadbearing floors.
Provides a suitable thermal insulation with its closed cell structure is a perfect solution for heavy-duty inverted roofs and floor structures.
Ravatherm XPS X 500 SL thermal insulation with its closed cell structure is a perfect solution for the thermal insulation of heavy-duty inverted roofs, floor structures and load-bearing base slabs.
Features and benefits:
Smooth surface skin (extrusion skin).
Homogeneous, closed-cell material structure comprised of extruded polystyrene (XPS), a rigid form of insulation.

To BS EN 13164.
Third party product certification
BRE, BBA, CE 13164.
To BS EN 13501-1.
Products contain an ecologically safe flame-retardant additive.
Compressive strength (minimum) at 10% compression
To EN 826. To plan the reinforcement steel requirements of floor slab used as a load-distribution structure over the thermal insulation layer, please consult a structural engineer.
Thermal conductivity (maximum)
Thickness dependent on required U-value and application.
Face size (length x width)
1250 x 600 mm.
The maximum installation depth of the thermal insulation is determined by the load: the horizontal pressure must not exceed the compressive strength of the boards, taking into account the value of the permanent load.
Smooth surface skin (extrusion skin). PE film separating and sliding layer between the thermal insulation and the concrete screed for installation on floor applications.
A grooved edge allowing boards to overlap, minimizing gaps.
Compressive creep (design load) maximum 2% deflection after 50 years
To EN 1606.
-50°C to +75°C maximum.
Provides the permanent application temperature of Ravatherm XPS X products. At higher temperatures, the boards will start to soften and suffer permanent deformation.
Thermal resistance (R-value)
(Rd m2 .K/W)
Country of product manufacture
Ravatherm XPS X uses carbon dioxide as a blowing agent, which gives it an ozone-depleting potential (ODP) of zero and a Global Warming Potential (GWP) of less than five.
