Installation Instructions 

 

Large Room Ceiling or Hidden Absorption

  • Go with the 2" thick version of EcoVerb rolls. The 2" EcoVerb™ is the most absorptive and is the best bang for your buck when rolling out a large amount of material on a ceiling or hiding material behind an architectural feature (wood slats, perforated acoustic panels).
  • Apply the EcoVerb™ Roll liner with the black finish facing outwards to give a blackout look.
  • Recommended Install Method: Stick Pins (ceiling), P329 Spray Adhesive (hidden absorption)

 

HVAC

  • Choose the correct thickness! If the liner is too thick, acoustics material will impede airflow. Small ducts (less than 10") should use the 1/2" thick liner. Larger ducts (12" x 12" or more) should use the 1" thick version. Commercial ducts (18" x 18" or more) use the 2" thickness.
  • For additional sound absorption, oversize your ducts (no more than 30%) to allow space for a thicker liner.
  • Install the EcoVerb™ Roll acoustic liner with the cotton side facing the inside wall of the duct. The black liner faces out towards where air is flowing. The facing protects the absorptive cotton fibers from airflow.
  • Recommended Adhesive: P329 Spray Adhesive, 3M Super 77, or equivalent

 

 

Common Product Uses

  • Line HVAC ducts with acoustical liner for air duct noise reduction and reduce heat gain/loss.
  • If you do not have full access to the HVAC duct, installing EcoVerb Roll Liner as far down as your arm can reach in each duct will still reduce noise by at least several decibels. If additional sound reduction is needed, contact us for details on how to build a baffle.
  • Roll EcoVerb™ Roll Liner out onto a wall or ceiling in a large room for a "blackout" look that blends well and adds excellent sound absorption (gyms, churches, bars, nightclubs, gun range soundproofing)
  • Commonly used behind perforated metal panels and perforated wood panels as "hidden absorption"
  • Line cargo area of Sprinter Van conversions with 2" EcoVerb™ Roll Liner for excellent sound and heat insulation
  • Vocal booths and voice over rooms
  • Garages
  • Mechanical rooms
  • Basements
