Product Reference | RAVATHERM XPS X 300 SLPrimarily used for inverted flat roofing application. |
Third party product certification | BRE, BBA, CE 13164 |
Fire performance | Euroclass ETo BS EN 13501-1. Products contain an ecologically safe flame-retardant additive. |
Compressive strength (minimum) at 10% compression | 300 kPaTo EN 826. |
Compressive creep (design load) maximum 2% deflection after 50 years | 130 kPaTo EN 1606. |
Thermal conductivity (maximum) | <60 mm - 0.030 W/m·KTypical thickness 50 mm to EN 13164. ≥60 mm- 0.031 W/m·KTypical thickness ranges between 80–205 mm to EN 13164. |
Thickness | Insert requirements. 50–200 mm thickness dependent on required U-value and application. |
Face Size (length x width) | 1250 x 600 mmThe 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. |
Recycled content | 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 |
Facing | SmoothSmooth surface skin (extrusion skin). |
Edges | Ship lapA grooved edge allowing boards to overlap, minimizing gaps. |
TemperatureRange | -50–75°C maximumProvides the permanent application temperature of Ravatherm XPS X products. At higher temperatures, the boards will start to soften and suffer permanent deformation. |
Standard product features | Colour: Grey. Features: Environmental friendly and a cost efficient solution. Finish: Smooth surface skin (extrusion skin). Material: Homogeneous, closed-cell material structure comprised of extruded polystyrene (XPS), a rigid form of insulation. Shape: Rectangular boards. Size: 1250 x 600 mm - Overall length x width per board. |

- BS EN 13501-1 - Fire classification of construction products and building elements. Classification using data from reaction to fire tests : Once the insulation is placed in the inverted roof, if the finishing used is that covered by the European Commission Decision EC 2000/553/EC, the designation of the roof is Broof(t4) hence complying with Requirement B4 (External Fire spread) of Approved Document B of the Building Regulations
