QuietR Duct Liner Board Product Data Sheet Description QuietR Duct Liner Board is a bonded board of glass fibers designed to be installed inside sheet metal ductwork or plenums with metal fasteners and adhesives. The smooth, fire-resistant airstream surface resists damage during installation and in service. The product complies with the requirements of National Fire Protection Association Standards NFPA 90A and 90B, qualifying them under other model codes. It is ideal for use in large ducts and plenums where air velocities do not exceed 6,000 fpm (30.5 m/s). Key Features Outstanding thermal and acoustical performance. Absorbs noise within the duct that helps create quiet and comfortable environments. Tough, abuse-resistant surface which reduces installation costs because these products resist damage. Cleanable surface with a black mat facing that provides a smooth, durable surface making it easier to clean the duct liners using methods and equipment described in North American Insulation Manufacturers Association (NAIMA) Publication AH122, Cleaning Fibrous Glass Insulated Duct Systems: Recommended Practice. Bacterial and fungal growth resistant with an EPA registered biocide that protects the airstream surface from microbial growth. Product Applications QuietR Duct Liner Board enhances indoor environmental quality by absorbing noise within sheet metal ducts. The product also contributes to indoor comfort by lowering heat loss or gain through duct walls. QuietR Duct Liners should not be used where operating temperatures will exceed 250F (121C). To avoid contact with liquid water, duct liner should be protected with a sheet metal sleeve and drip pan adjacent to equipment such as evaporative coolers, humidifiers, cooling coils and outside intakes. When duct systems run through unconditioned space and are used for cooling only, register openings must be tightly sealed to prevent water vapor accumulation in the system during the heating season. When duct liners are used in systems supplying hospital Availability QuietR Duct Liners are available in the following combinations of thicknesses and types: R-values, hrft 2 F/Btu (RSI, m 2 C/W) at 75F (24C) mean temperature Product Type and Thickness Nominal Density pcf (kg/m 3 ) 1.0 in (25mm) 2.0 in (51mm) QuietR Duct Liner Board 3.0 (48) 4.3 (0.76) 8.7 (1.53) QuietR Duct Liner Board is available in the following standard sizes: 1" x 48" x 96" (26mm x 1219mm x 2438mm), 2" x 48" x 96" (51mm x 1219mm x 2438mm), 2" x 48" x 120" (51mm x 1219mm x 3048mm).

When wet, coated surfaces of QuietR Duct Liner Board 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, ASTM E 84, NFPA 255, and CAN/ULC-S102. These standards 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.
