Description

Mineral, lay-in ceiling tiles with a finely textured and durable surface with a brighter ‘blue-white’ colour and high light reflectance which offers high levels of sound absorption and sound attenuation.

Features and benefits:

  • Balanced acoustic sound absorption of 0.70 αw and sound attenuation of 39 dB.
  • Bright 'blue-white' colour with a high light reflectance.
  • Reinforced scratch resistant surface.
  • Hard edge treatment.
  • Low volatile organic compound (VOC) emissions, A+ rating.
  • 100% recyclable.
  • Manufactured using 37% (maximum) recycled material.
  • Cradle to Cradle™ certified.
  • 30-year system guarantee.

Load capacity:

  • Varies with layout, grid type, tile selected and hanger spacing. Consult manufacturer's technical sales department for details. info@armstrongceilingsolutions.co.uk
  • Fittings exceeding the load capacity or with dynamic characteristics (such as air diffusers) will need independent suspension.

Grids:

Compatible grid: System Z-L-Bar. To be specified separately; consult manufacturer for details.

Applications:

  • Meeting rooms and waiting areas.
  • Open areas and corridors.

Acoustic absorption:

Weighted sound absorption coefficient (alpha w). Rating for random incidence sound absorption determined in accordance with BS EN ISO 11654. Measured values obtained in accordance with BS 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.
