acoustics

In order to improve interior sound control, the Luxalon® multi-panel closed ceiling panels can be perforated and also fitted with non-woven acoustic tissue.




 

• curve 1 (75C):
  

  75C panels with Ø 1 mm holes. The reverse side of the panels is provided with black non-woven tissue glued over the whole perforated area. Plenum depth is 200 mm. The sound absorption curve has been taken from test report nr. 124.022 of TNO Delft.

• curve 2 (150C/225C):
  
  150C panels with Ø 2 mm holes. The reverse side of the panels is provided with black non-woven tissue glued over the whole perforated area. Plenum depth is 200 mm. The sound absorption curve has been taken from test report nr. 124.022 of TNO Delft.

The sound absorption curve for 225C panels with Ø 2 mm holes and non-woven tissue will resemble curve 2.

• curve 3 (75C):
  
  Perforated 75C panels with Ø 1 mm holes. Between the carriers a 25mm thick mineral wool pad with a density of approx. 22 kg/m3, plenum depth 200 mm. The sound absorption curve has been taken from test report no. 823.066 of TNO Delft.

• curve 4 (225C):
  
  300C panels with Ø 1,5 mm holes. The reverse side of the panels is provided with black non-woven tissue glued over the whole perforated area. Plenum depth is 400 mm. The sound absorption curve has been taken from test report nr. TPD-HAG-RPT-94-0037 of TNO Delft.

The sound absorption curve for 225C panels with Ø 1,5 mm holes and non-woven tissue will resemble curve 4.
