PRODUCT DATA SHEET QuietR Duct Board Description Owens Corning QuietR Duct Board is a rigid, resin bonded fibrous glass board with a tough, damage-resistant, flame retardant, reinforced aluminum foil (FRK) facing; with a durable mat air stream surface. Features Absorbs noise and reduces popping noises caused by expansion, contraction and vibration Assured thermal R-value performance Bacterial and fungal growth resistant with an EPA registered biocide that helps protect the air stream surface from microbial growth Thermal/acoustical insulation board plus jacket forms a single component duct system, thus reducing inspection time Lightweight boards are easier to transport and handle than insulated sheet metal ducts Virtually eliminates air leakage thus saving energy and removing the need for system overdesign Physical Properties Property Test Method Value Maximum Operating Temperature Limits UL 181/ULC S110 Internal: 250F (121C) External: 150F (66C) Maximum Air Velocity UL 181/ULC S110 Erosion Test 6,000 fpm (30.5 m/s) Static Pressure Limit UL 181/ULC S110 2 in. w.g.

The surface burning characteristics of these products have been determined in accordance with UL 723/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. Availability Type Thickness Density, pcf (kg/m3) Type 475 1" (25mm) 4.4 (70) Type 800 1" (38mm) 3.8 (61) Type 1400 2" (51mm) 3.8 (61) Type designates board stiffness defined by flexural rigidity. Type selection depends on duct size, pressure and reinforcement schedule. The 1" (38mm) and 2" (51mm) thickness provides superior thermal value.

Therefore, reason- able tolerances must be applied. Tests were conducted in accordance with ASTM C423, Mounting A (material applied against a solid backing.) Applications QuietR Duct Board may be used to fabricate components for indoor commercial and residential heating, ventilating and air conditioning duct systems operating at static pressures to 2 in. w.g. (500 Pa), internal air temperatures 40F (4C) to 250F (121C), and air velocities to 6,000 fpm (30.5 m/s). Straight duct sections, elbows, tees, offsets and other system elements can quickly and easily be fabricated at the shop or on the job and assembled into a complete air distribution system using these lightweight, thermally efficient boards. Technical Information National Fire Protection Association Standards NFPA 90A and 90B for air conditioning and ventilating systems require air ducts to be Class 0 or 1. The tests set stringent requirements on fire safety as well as ruggedness. To meet Class 1 air duct requirements, the system must withstand UL 181/ULC S110 tests such as erosion, pressure loss, impact, collapse, puncture, static load and fire retardancy (30 minute flame penetration test). Also, to qualify as a Class 1 Air Duct System, the following UL 723/ULC S102 fire testing requirements must be met: Flame Spread, 25; Smoke Developed, 50.
