FIBRANgeo Designation Code
Print

All FIBRANgeo stonewool insulation products conform to the European Directive 89/106/EEC since 2004. In compliance with the above Construction Products Directive, all types of FIBRANgeo stonewool products hold the CE marking. Further, they are in conformity with the European Norm EN 13162, which refers to mineral wool insulation products used in building applications. In accordance with the aforementioned European Standard, every insulation product acquires a designation code which declares its technical characteristics.

For example:

MW - EN 13162 – Ti - CS(10)i – Tri - PL(5)i – CPi – WS - WL(P) – MUi – SDi - AFri - Awi

 

• MW –Factory made mineral wool insulation material, manufactured from molten rock, slag or glass.

• EN 13162 – The European Standard number

• Ti – Thickness Tolerances. Classes for thickness tolerances from the nominal thickness (e.g. Class T4 :  - 3mm + 5mm).

• CS(10)i – Compressive stress at 10% thickness deformation (kPa). The compressive stress measurement should be greater than the declared value.

• TRi – Tensile strength perpendicular to faces (kPa). Tensile strength is measured perpendicular to the surface of the board and should be greater than the declared value.

• PL (5)i – Point Load (N). Compressive force (applied on a small area of 50 cm²) at 5 mm thickness deformation. The measurement should be greater than the declared value.

•CPi – Compressibility (mm). The difference between the unloaded thickness dLand the loaded thickness dB.  The measured difference should be less than the declared value.

• WS – Short Term Water Absorption (kg/m²).  Partial immersion of the material in water for 24 hours.  The water absorption should be less than 1 kg/m².

• WL(P) – Long Term Water Absorption (kg/m²). Partial immersion of the material in water for 28 days.  The water absorption should be less than 3 kg/m².

• MUi – Water Vapour Transmission.  Measured as theratio ‘μ’ of water vapour diffusion resistance of the material to the resistance of an equal thickness of air.  The measured coefficient ‘μ’ should be less than the declared.  

• SDi – Dynamic Stiffness (MN/m³) at a particular thickness. Measured as the ratio s’ of dynamic compressive stress to dynamic change in thickness, and should be less than the declared value.

• AFri – Air flow resistivity (kPa s/m²). Measured as the air flow resistance of the material and should be greater than 5 kPa s/m².

• AWi -Weighted Sound Absorption Coefficient. The value of the sound absorption coefficient ‘αw’ in the frequency of 500Hz, measured on the standard weighted sound absorption curve.

NOTE :

The thermal conductivity λD and the thermal resistance RD, as well as the fire classification, are also declared on the insulation product’s label.
