Installation Method:

  • Suspend baffles using coated wire/ties and other fastener as required through grommets.
  • Installation is best done at the end of the construction project
  • Do not install material of unacceptable quality or pre-install suspension hardware (grommet locations may vary slightly)
  • All sizes are nominal and are subject to manufacturing tolerances that may vary +/- 1/8″. Due to the manufacturing process and the inclusion of recycled content, there may be color inconsistencies – including dye lot variations – flecks, specks, and other slight surface blemishes are unavoidable.
