Perla OP dB

Application

  • Suitable for specific flexible environments.
  • Libraries.
  • Language rooms.

Description

Perla OP dB combines smooth Perla laminated appearance with the highest levels of sound absorption and sound attenuation in one tile, providing a solution for flexible working spaces.

Features and benefits:

  • Offers an acoustical combination of high sound absorption and high sound attenuation properties.
  • Low volatile organic compound (VOC) emissions, A+ rating.
  • 100% recyclable and uses 36% recycled material.
  • 15-year product guarantee.
  • 30-year system guarantee.

Load capacity:

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

Standard product features

Technical characteristics:

  • Thickness: 40 mm.
  • Weight: 6.2 kg/m².
  • Light reflectance value (LRV): 85%.
  • Clean room classification ISO 5.
  • Reaction to fire to EN 13501-1: Euroclass A2-s1, d0.
  • Thermal conductivity 0.037 W/m·K.
  • Sound absorption NRC: 0.85.
  • Humidity resistance (RH): 95%.
  • Acoustic absorption (weighted sound absorption coefficient): αw = 0.90.
  • Acoustic attenuation (weighted suspended ceiling normalized level difference): Dnfw = 40 dB.

Sound 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.

Sound reduction index:

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.
