Introduction 1 7 / 8 " 1" This publication provides dimensional data required for accurate fabrication of insulated duct systems using 2" (R-8.7) fibrous glass duct board. General fabrication principles for 2" fibrous glass duct board are basically the same as for 1" and 1 1 / 2 " duct board. For complete detailed duct board fabrication guidelines, refer to NIM Fibrous Glass uct onstruction Standard, 5 th Edition (2002), Publication H 116. Thermal Performance Thermal resistance (R-value) of 2" fibrous glass duct board is 8.7, which enables it to comply with energy codes requiring duct system R-values of at least 8.0. Male Shiplap Tool: uts male slip joint to mate with female slip joint to connect two duct sections. 1 7 / 8" 7 / 8 " 1 7 / 8" 15 / 16 " Modified Shiplap Tool: Removes insulation for shiplap corner folds. Reversing tool allows both left and right hand cuts to be made. Fabrication oth hand and machine grooving tools are available for fabricating 2 fibrous glass duct board. grooving tools are shown at right. orrect tool blade settings are very important in assuring accurate fabrication, tight joints, and an air-tight duct system that performs to specifications. imensions shown are nominal and may vary among tool manufacturers. 3 3 / 4 " 1 7 / 8 " V-Groove Tool: uts 90 V-grooves for corner folds when modified shiplap grooving method is not used. losure losure of longitudinal and transverse joints using 2" fibrous glass duct board is the same as with 1" or 1 1 / 2 " duct board, except that UL 181/P pressure-sensitive closure tapes must be 3" wide. 1 3 / 4" 2 1 / 8 " 1 3 / 4" 1" Shiplap / End utoff Tool: uts shiplap on end of board for longitudinal corner closure plus staple flap. 2

Its role is to promote energy efficiency and environmental preservation through the use of fiber glass, rock wool, and slag wool insulation, and to encourage the safe production and use of these materials. In May 1999, NIM began implementing a comprehensive voluntary work practice partnership with the U.S. Occupational Safety and Health dministration (OSH). The program, known as the Health and Safety Partnership Program, or HSPP, promotes the safe handling and use of insulation materials and incorporates education and training for the manufacture, fabrication, installation and removal of fiber glass, rock wool and slag wool insulation products.
