  • Thickness: 9 mm
  • Dimension: 1200 mm X 2400 mm
  • Density: 237 kg/m3 (Testing method: ASTM D 1752)
  • Polysorb Acoustic Wall Panel is lightweight and flexible along with excellent
  • tension/compression stiffness.
  • The tile maintains its dimensions in high humidity and temperature.
  • The color of the tile maintained even in long term exposure to sunlight (over 4th grade in 240
  • his at 100°C).
  • The surface of the tile is resistant to surface wetting (rate of resistance to surface wetting: 99.6%)
  • therefore inhabitation of various germs and molds is inhibited.
  • Furthermore, the panel can be easily cut into any desired shape.


The Polysorb Acoustic Wall Panel can attain a maximum NRC of up to 0.60

The absorption coefficient over important speech frequencies are as follows

Frequency (Hz) 250 500 1000 2000
NRC 0.18 0.54 0.83 0.81


The Polysorb Acoustic Wall Panel offers robust fire performance and does not generate any toxic gases on combustion.
