Owens Corning QuietR® Rotary Duct Liner

Manufacturer: Owens Corning
Product Description

Owens Corning QuietR® Rotary Duct Liner is an outstanding thermal and acoustic performance that absorbs noise from fans and air turbulence, as well as reduces popping noises within sheet metal ducts, to enhance indoor quality. Resistant to bacterial and fungal growth. You will be comfortable indoors by lowing heat loss or gain through duct walls.

Product is intended for professional installation in commercial and industrial applications only.


Standards, Code Compliance

  • ASTM C1071, Type I, Flexible (replaces obsolete Federal Specification HH-1-545B.)
  • NFPA 90A/90B
  • ICC Compliant
  • California Title 24
  • SMACNA Application Standard for Duct Liners
  • NAIMA Fibrous Glass Duct Liner Installation Standard
  • Conforms to ASHRAE 62-2001
  • 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® Rotary 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® Rotary 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. For fastener spacing, see Figure 1.

Duct Liner shall be cut to assure overlapped and compressed longitudinal corner joints. For details, refer to NAIMA Publication AH124, Fibrous Glass Duct Liner Standard.

Minor damage and small tears may be repaired by coating with adhesive.

After installation, and prior to occupancy, blow out duct system to remove any cutting scraps or foreign material remaining in the duct.

Installing two layers of material to meet a specific liner thickness is not recommended. If the specification forces the use of multiple layers, the following steps must be taken:

1. Adhere bottom layer of duct liner to duct in normal manner.

2. Adhere top layer to bottom layer of liner using a minimum of 90% adhesive coverage.

3. Treat all leading edges with metal nosings to prevent separation of the two layers.

4. Use mechanical fasteners of the proper length for double layer.
