Product Data Sheet QuietR Rotary Duct Liner Description QuietR Rotary Duct Liner enhances indoor quality by absorbing noise within sheet metal ducts, and contributes to indoor comfort by lowering heat loss or gain through duct walls. 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 helps protect 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. 1501 rolls are rolled with the veil to the outside. 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.

When wet, coated surfaces of QuietR Rotary Duct Liner in contact with galvanized steel may cause discoloration of the sheet metal. 2. The surface burning characteristics of these products have been determined in accordance with UL 723 or CAN/ULC-S102. This standard should be used to measure and describe the properties of materials, products or assemblies in response to heat and flame under controlled laboratory conditions and should not be used to describe or appraise the fire hazard or fire risk of materials, products or assemblies under actual fire conditions. However, results of this test may be used as elements of a fire risk assessment which takes into account all of the factors which are pertinent to an assessment of the fire hazard of a particular end use. Values are reported to the nearest 5 rating. UL 723 and ASTM E84 are the same test methods.
