39 STANDARDS & CODES COMPLIANCE NFPA 90A and 90B ASTM C1290, Flexible Fibrous Glass Blanket Insulation Used to Externally Insulate HVAC Ducts, Type III ASTM C1136, Flexible Low Permeance Vapor Retarders for Thermal Insulation, Type II (facing only) ASTM C553* Mineral Fiber Thermal Insulation: Type I - Fiberglas Duct Wrap Type 75; Type II - SOFTR Duct Wrap FRK Types 100 and 150. (Operating temperatures to 250F (121C) and thermal values to 150F (66C) mean. *Preferred specification is ASTM C1290. NOTE TO SPECIFIERS - Federal Specification HH-I-558B (Amendment 3), Form B (covering the duct wrap), and Federal Specification HH-B-100B (Covering the facing and CAN/CGSB-51.11), are obsolete. These are replaced by the above referenced ASTM specifications. CERTIFICATIONS & SUSTAINABILITY Certified by SCS Global Services to contain a minimum of 53% recycled glass content, 31% pre-consumer and 22% post-consumer. Certified to meet indoor air quality standards under the stringent GREENGUARD Indoor Air Quality Certification Program, and the GREENGUARD Gold Certification. Nominal duct wrap thickness to prevent surface condensation The above chart is based on indoor conditions so far as wind and other factors are concerned. Thermal conductivity Apparent thermal conductivity curve determined in accordance with ASTM Practice C1045 with data obtained by ASTM Test Method C177. Values are nominal, subject to normal testing and manufacturing tolerances. SoftR Duct Wrap Installation instructions 1. Ensure that ducts are clean, dry and tightly sealed at joints and seams. 2. Cut to stretch-out dimensions and remove 2" of insulation from facing. 3. Install duct wrap tightly butted with facing outside. (Make sure to not excessively compress at duct corners). 4. Adjacent sections should have the 2" tape flap overlapping 5. Seams should be stapled 6" on center with outward clinching staples. 6. Seal all seams and joints with matching pressure sensitive tape or with glass fabric and mastic. 7. On rectangular ducts 24" or wider, SoftR Duct Wrap should be secured at the bottom of the duct with mechanical fasteners to prevent sagging of insulation. 8. Where a vapor retarder is required, cover and repair any facing tears/punctures with matching vapor sealing, pressure-sensitive patches/tape. Product should be kept dry during shipping, storage and installation. It should not be used on the inside of ducts.
