Third party product certification
BRE, BBA, CE 13164.
Euro class E, to BS EN 13501-1.
Compressive strength (minimum) at 10% compression
To EN 826.
Thermal conductivity (maximum)
Typical thickness 50 mm to EN 13164.
50–200 mm 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).
A grooved edge allowing boards to overlap, minimizing gaps.
RAVATHERM XPS X 300 SL
Primarily used for inverted flat roofing application.
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.
