Third party product certification
Euro class E, Class A1, 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)
<60 mm - 0.030 W/m·K.
Typical thickness 50 mm to EN 13164.
Face size (length x width)
1200 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.
6 mm fibre cement flat sheet.
Fibre cement topping on external face Ravatherm XPS X 300 SB.
This product must be laid with no gaps between the boards in structures with contact to soil. For gluing, solvent-free adhesives must be used. Follow the supplier’s guidance.
RAVATHERM XPS X UB300
Primarily used for parapets and upstands.
-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.
