  • Finish: Pregalvanized. Electrostatically applied polyester powder coating. Thickness (minimum): 55 µ. Choice of colour.
  • Choice of size.
  • Reaction to fire: Euroclass A2-s1, d0.
  • Suitable for environments up to 95% relative humidity, as standard. Selected model available painted front-and-back for environments up to 100% RH.
  • Suitable for incorporation of air diffusers, sprinklers and luminaires – consult Armstrong. Factory cut openings can be provided. Compatible air diffusers and luminaires are available, supplied by others – consult Armstrong.
  • 15 year guarantee.

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 value will vary between 0.00 and 1.

Acoustic attenuation:

Dncw 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 20140-9 over the third-octave band frequency range 100–3150 Hz.

Load capacity:

  • Varies with layout, grid range, panel range, hanger spacing. Consult Armstrong. Load capacity tables are available.
  • Fittings exceeding the load capacity or with dynamic characteristics (such as air diffusers) may need independent suspension.

Grid (specified elsewhere):

  • System 3000 with spring A bar - For Q Clip / Q Clip F / R Clip and S Clip F.
  • C Channel with Spring T - For T Clip F 5 mm bevel edge tiles.
