QuietR Duct Liner Board Product Data Sheet 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. Installation All portions of duct designated to receive duct liner shall be completely covered with QuietR Duct Liner Board, 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 faced surface of the duct liner shall face the airstream. QuietR Duct Liner Board 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. QuietR Duct Liner Board shall be cut to assure tight, overlapped corner joints. The top pieces shall be supported at the edges by the side pieces. 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 leading edges with metal nosings to prevent separation of the two layers. 4. Use mechanical fasteners of the proper length for double layers. Technical Information Mold in duct systems occurs when moisture comes into contact with dirt or dust collected on the duct system surfaces. Proper filters will minimize the collection of dust and dirt, but care needs to be exercised to prevent water formation in the duct. A properly sized, installed and operated air conditioning unit will minimize the likelihood of water formation. The system must be maintained and operated to insure that sufficient dehumidification is occurring and that filters are installed and changed as recommended by the equipment manufacturer.
