• Design rules for DECI-TEX family product are
  similar although for different applications there
  are specific acoustic materials
• DECI-TEX P10 - acoustic fabric for architectural
  applications
• DECI-TEX P41 - low frequency enhancer for mineral
  wool polyester
• DECI-TEX P44 - acoustic fabric for perforated
  slotted panels
• DECI-TEX P52 - acoustic fabric for acoustic
  panels, acoustic baffles and underbonnet
  insulator
• DECI-TEX P70 - acoustic board for specific
  automotive applications
• DECI-TEX PB DECI-TEX WL - pinnable acoustic
  wall lining
• DECI-TEX Sound Baffle

CONCLUSIONS

• Unlimited application scope
• High acoustic performance across wide frequency
  range, in particular at small air gaps
• Environmental friendly product, 100 polyester
• Light weight, important in particular in the
  automotive industry
• Conversion of standard fabrics into acoustic
  materials
• Enhancement of the acoustic performance on
  traditional bulk materials
