Extruded polystyrene (XPS) thermal insulation for inverted flat roof construction.
Suitable use in a wide range of roofing and flooring applications including inverted roofs, green roofs, roof terraces and car park decks.
Ravatherm XPS X 300 SL is a high-performance, multi-purpose polystyrene for the thermal insulation and frost protection of inverted flat roofs, green and blue roofs.
Features and benefits:
Smooth surface skin (extrusion skin)
Homogeneous, closed-cell material structure comprised of extruded polystyrene (XPS), a rigid form of insulation
J21/440 Inverted roof insulation
J41/440 Inverted roof insulation
J42/440 Inverted roof insulation
P10/135 Insulation laid across ceiling ties/ joists
P10/148 Multilayer blanket insulation fixed under or above rafters
Q37/310 Inverted roof insulation
To BS EN 13164.
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.
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
A1-A3 (production stage) as defined in BS EN 15804
2.77 kg CO₂ eq/kg
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.
