CE FIBRANxps

All FIBRANxps extruded polystyrene insulation products conform to the European Regulation (CPR) 305/2011, which replaced the European Directive 89/106/EEC.  In compliance with CPR, all types of FIBRANxps are in conformity with the European DIrective 99/91/ECC, they are assessed for the verification of performance stability using system 3 / 2+ and bear the CE marking, in accordance with the European Standard EN 13164, which pertains to extruded polystyrene products for building insulation. In accordance with the European Νorm EN 13164, every insulation product acquires a designation code, which declares its technical characteristics.

For example:

XPS- EN 13164-Ti- DS(TH)- CS(10)i- TRi- WL(T)i-WD(V)i- MUi

• XPS – Extruded polystyrene foam boards with closed-cell structure
• EN 13164 – The European Standard number.
• Ti – Thickness Tolerances. Classes for thickness tolerances from the nominal thickness (e.g. Class Τ1: -2mm +2/3mm, Τ3: -1mm +1mm).
• DS(70,90)– Dimensional stability under specified temperature and humidity conditions (70°C, 90%).
• CS(10)i – Minimum compressive stress at 10% thickness deformation (kPa).
• TRi – Minimum tensile strength perpendicular to faces (kPa).
• WL(Τ) – Long-term water absorption (Vol.%) by total Immersion for 28 days
• WD(V) – Water absorption (Vol.%) diffusion.
• MUi – Water Vapour Transmission. The maximum ratio (factor μ) of water vapour diffusion resistance of the material to the resistance of an equal thickness of air.

Note:

The thermal conductivity λ₀ and the thermal resistance R_D, as well as the fire classification should also be declared.

• λ₀ - eclared Thermal Conductivity (W/mK). The maximum expected nominal thermal conductivity during the material’s working life, at mean temperature 10 °C (greater than the test results), in accordance with EN 13162. Thermal conductivity λ (W/mK) is the heat amount transmitted through a layer of material, with 1 m² surface area and 1 m thickness, when a constant temperature difference of 1 K is maintained between the layer’s faces.
• R_D - Declared Thermal Resistance (m²K/W). The minimum expected nominal thermal resistance during the material’s working life, at a mean temperature of 10 C (less than the test results), in accordance with EN 13162. Thermal resistance R (m²K/W) is the ratio of the material’s thickness d to the material’s thermal conductivity λ.
• Fire Classification – Building materials are classified depending on their reaction to fire in Classes A1 (non-combustible), A2, B, C, D, E to F (no performance determined), in accordance with EN 13501-1.
