Acoustic Rotary Duct Liner 1/2″ x 47-1/2″ x 100′ Roll R2.2

Key Features:

• Absorbs fan and air turbulence noise and reduces popping noises within sheet metal ducts.
• Outstanding thermal and acoustical performance.
• Bacterial and fungal growth resistant with an EPA registered biocide that protects the airstream surface from microbial growth.

Product Applications/Installation:

• All portions of duct designated to receive QuietR Textile Duct Liner shall be completely covered with duct liner, adhered to the sheet metal with 90% coverage of adhesive complying with ASTM C 916. Transverse joints shall be neatly butted and there shall be no interruptions or gaps.
• All transverse joints shall be edge coated. Metal nosing on leading edges must be used where duct liner is preceded by unlined metal, and on all upstream edges when velocity exceeds 4,000 fpm (20.3 m/s). The black mat faced surface of the duct liner shall face the airstream.
• QuietR Textile Duct Liner shall also be secured with mechanical fasteners, either impact-driven or weld-secured, which shall compress the duct liner sufficiently to hold it firmly in place. Duct liner shall be cut to assure over-lapped and compressed longitudinal corner joints.
• For details, refer to NAIMA Publication AH124, Fibrous Glass Duct Liner Standard.

Limitations:

• Use of QuietR Textile Duct Liner is not recommended for the following applications:
  • With wood or coal fired equipment, or equipment of any type which does not include automatic maximum temperature controls and where operating temperatures of 250F (121C) may be exceeded.
  • In kitchen or fume exhaust ducts, or ducts conveying solids or corrosive gases.
  • In any application where the duct liner may come in direct contact with liquid water (such as cooling coils, humidifiers, and evaporative coolers) unless protected from the water source.
  • Inside fire damper sleeves.
  • Immediately adjacent to high temperature heating coils without radiation protection.
