Continuous production may require periodic pauses to allow sealing iron to recover to 650ƒF (343ƒC). f. Allow joint to cool before stressing. 3. Mastic and Glass Fabric Any mastic and glass fabric closure system listed and labeled under UL 181, Part III (M). a. All longitudinal and circumferential joints must be stapled with outward fl aring ‡ "(13mm) (min.) staples, 2" (50mm) (approx.) O.C. b. Brush mastic onto joint and embed glass fabric in mastic. c. Brush second coat of mastic over fabric until completely fi lled. d. Allow joints to dry in accordance with mastic manufacturerís recommendation before pressurizing system. Description Owens Corning EnDuraGold FIBERGLAS Duct Board is a rigid, resin bonded fi brous glass board with a tough, damageresistant, fl ame retardant, reinforced aluminum foil (FRK) facing. When fabricated into duct systems, it combines excellent thermal and acoustical insulating properties with substantially airtight transmission of air when all joints are sealed with UL 181A listed closures. EnDuraGold FIBERGLAS Duct Board features a durable mat air stream surface that isolates the glass fi ber substrate from the airstream and inhibits penetration of the insulation by dirt, dust and other pollutants. This durable air stream surface makes it easy to clean the duct system using methods and equipment described in North American Insulation Manufacturers Association (NAIMA) Publication AH122, Cleaning Fibrous Glass Insulated Duct Systems, Recommended Practice. Uses EnDuraGold FIBERGLAS 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 40ƒF (4ƒC) to 250ƒF (121ƒC), 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 transmission system using these lightweight, thermally effi cient boards. Product Attributes Bacterial and Fungal Growth Resistance A durable air stream surface includes an EPA registered biocide that protects the air stream surface from microbial growth and meets requirements of ASTM C 1338, ASTM G 21 (fungi test) and ASTM G 22 (bacteria test). Tips to Avoid Mold Growth in Ducts Mold in duct systems occurs when moisture comes into contact with dirt or dust collected on the duct system surfaces. Proper fi lters will minimize the collection of dust and dirt, but care needs to be exercised to prevent water formation in the duct. A properly sized and operated air conditioning unit will minimize the likelihood of water formation. The system must be maintained and operated to insure that suffi cient dehumidifi cation is occurring and that fi lters are installed and changed as recommended by the equipment manufacturer. Assured Thermal Performance R-values as published for EnDuraGold FIBERGLAS Duct Board are superior to those of compressible insulation of equal thickness. Factory control of thickness assures that installed R-values will be as published for Typical Physical Properties Property Test Method Value Maximum Operating Temperature Limits UL 181 Internal: 250ƒF (121ƒC) External: 150ƒF (66ƒC) Maximum Air Velocity UL 181 Erosion Test 6,000 fpm (30.5 m/s) Static Pressure Limit UL 181 2 in. w.g.

This standard should be used to measure and describe the properties of materials, products or assemblies in response to heat and fl ame under controlled laboratory conditions and should not be used to describe or appraise the fi re hazard or fi re risk of materials, products or assemblies under actual fi re conditions. However, results of this test may be used as elements of a fi re risk assessment which takes into account all of the factors which are pertinent to an assessment of the fi re hazard of a particular end use.
