Round 1 Bowling and Amusement 12/09/2024 Paradigm Design <br />Main Place Mall Expansion Grand Rapids, MI <br />Santa Ana, California <br />Project #2309147GR <br />HVAC INSULATION 23 0700 - 19 <br />1.Comply with requirements in Division 07 Section "Penetration Firestopping" and fire- <br />resistive joint sealers. <br />F.Insulation Installation at Floor Penetrations: <br />1.Duct: Install insulation continuously through floor penetrations that are not fire rated. <br />For penetrations through fire-rated assemblies, terminate insulation at fire damper sleeves <br />and externally insulate damper sleeve beyond floor to match adjacent duct insulation. <br />Overlap damper sleeve and duct insulation at least 2 inches. <br />2.Pipe: Install insulation continuously through floor penetrations. <br />3.Seal penetrations through fire-rated assemblies. Comply with requirements in <br />Division 07 Section "Penetration Firestopping." <br />3.5 MINERAL-FIBER INSULATION INSTALLATION <br />A.Blanket Insulation Installation on Ducts and Plenums: Secure with adhesive and insulation <br />pins. <br />1.Apply adhesives according to manufacturer's recommended coverage rates per unit area, <br />for 100 percent coverage of duct and plenum surfaces. <br />2.Apply adhesive to entire circumference of ducts and to all surfaces of fittings and <br />transitions. <br />3.Install either capacitor-discharge-weld pins and speed washers or cupped-head, capacitor- <br />discharge-weld pins on sides and bottom of horizontal ducts and sides of vertical ducts as <br />follows: <br />a.On duct sides with dimensions 18 inches and smaller, place pins along longitudinal <br />centerline of duct. Space 3 inches maximum from insulation end joints, and 16 <br />inches o.c. <br />b.On duct sides with dimensions larger than 18 inches, place pins 16 inches o.c. each <br />way, and 3 inches maximum from insulation joints. Install additional pins to hold <br />insulation tightly against surface at cross bracing. <br />c.Pins may be omitted from top surface of horizontal, rectangular ducts and plenums. <br />d.Do not overcompress insulation during installation. <br />e.Impale insulation over pins and attach speed washers. <br />f.Cut excess portion of pins extending beyond speed washers or bend parallel with <br />insulation surface. Cover exposed pins and washers with tape matching insulation <br />facing. <br />4.For ducts and plenums with surface temperatures below ambient, install a continuous <br />unbroken vapor barrier. Create a facing lap for longitudinal seams and end joints with <br />insulation by removing 2 inches from 1 edge and 1 end of insulation segment. Secure <br />laps to adjacent insulation section with 1/2-inch outward-clinching staples, 1 inch o.c. <br />Install vapor barrier consisting of factory- or field-applied jacket, adhesive, vapor-barrier <br />mastic, and sealant at joints, seams, and protrusions. <br />a.Repair punctures, tears, and penetrations with tape or mastic to maintain vapor- <br />barrier seal.
