Standard product features

Technical characteristics:

  • Thickness: 19 mm.
  • Colour: White.
  • Light reflectance value (LRV): 85%.
  • Weight: 7.9 kg/m².
  • Thermal conductivity: 0.067 W/m·K.
  • Reaction to fire: Euroclass A2-s1, d0.
  • Recycled content to ISO 14021 (maximum): 37%.
  • Acoustic absorption (weighted sound absorption coefficient) αw = 0.60.
  • Acoustic attenuation (weighted suspended ceiling normalized level difference) Dnfw = 39 dB.

Acoustic absorption:

Weighted sound absorption coefficient (alpha w). Rating for random incidence sound absorption determined in accordance with EN ISO 11654. Measured values obtained in accordance with EN ISO 20354 are converted into octave bands, plotted on a graph and compared to a standard reference curve until a 'best fit' is obtained. The derived αw will vary between 0.00 and 1.00.

Acoustic attenuation:

Dnfw rating derived from laboratory measurement of room-to-room airborne sound insulation of suspended ceiling with plenum above. Rating determined in accordance with EN ISO 717-1 from measurements made in accordance with EN IS0 10848-2 over the third-octave band frequency range 100–3150 Hz.
