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 up to 0.75 αw and sound attenuation of 40 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 (except Vector: 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 grids, by edge detail. To be specified separately; consult manufacturer for details.

Acoustic absorption (weighted sound absorption coefficient):

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.

  • Board, Tegular, MicroLook 90 and Finesse αw = 0.70 (H).
  • Vector:0.75 (H).
  • SL2: 0.75 (H).

Acoustic attenuation (weighted suspended ceiling normalized level difference):

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.

  • Board, Tegular, MicroLook 90 Dnfw = 36 dB.
  • Vector: 33 dB.
  • Finesse: 39 dB.
  • SL2: 40 dB.
