Standard | To BS EN 13164. |
Third-party certification | BRE, BBA, CE 13164. |
Fire performance | Euro class E, to BS EN 13501-1. |
Compressive strength (minimum) at 10% compression | 300 kPa.To EN 826. |
Thermal conductivity (maximum) | 0.030 W/m·K.Typical thickness 50 mm to EN 13164. |
Thickness50–200 mm thickness dependent on required U-value and application. | 50 mm. |
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. |
Facing | Smooth.Smooth surface skin (extrusion skin). |
Edges | Ship lap.A grooved edge allowing boards to overlap, minimizing gaps. |
Compressive creep (design load) maximum 2% deflection after 50 years | 130 kPa. To EN 1606. |
TemperatureRange | -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) | 1.65. |
Country of product manufacture | United Kingdom |
Embodied carbonA1-A3 (production stage) as defined in BS EN 15804 | 2.77 kg CO₂ eq/kg |
Recyclability | 100% |
Recycled contentRavatherm 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. | - |
