Significance and Use4.1 This practice recognizes that effectiveness, safety, anddurability of insulation depend not only on the quality of theinsulating materials but also on their proper installation.4.2 This practice provides general

18、 procedures that will helpto ensure installation of insulation in a safe and effectivemanner. It shall be noted that actual conditions in existingbuildings vary greatly and in some cases additional care shallbe taken to ensure effective and safe installation.5. Safety Precautions5.1 The installer sh

19、all wear proper clothing and equipmentas recommended by the insulation manufacturer.5.2 In areas where insulation is to be installed, componentsof the electrical system shall be in good condition. If there isreason to believe the electrical system is faulty, do not installinsulation in such areas un

20、til the owner has been informed andrepair has been accomplished.NOTE 1The CPSC Product Safety Fact Sheet No. 518 has identifiedthe following signs of electrical deficiencies: lights dimming, fusesblowing, circuit breakers tripping frequently, electrical sparks and “glow-ing” from receptacles, light

21、flickering, and coverplates on switches andoutlets that are warm or hot to the touch.6. Pre-installation Inspection and Preparation6.1 Inspect the roof, walls, ceilings, and attic floors toidentify areas where previous or existing moisture problemshave caused paint peeling, warpage, staining, visibl

22、e fungusgrowth, rotting, or other structural damage. Do not installinsulation in such areas until the owner has been informed andhas certified that these conditions have been corrected and theirsource(s) of moisture eliminated.6.2 Provide proper attic ventilation in accordance with localbuilding req

23、uirements or practices, such as the ICC Interna-tional Residential Code.6.3 When the attic has soffit vents at the eaves, makeprovisions to prevent insulation from blocking the vents andrestricting attic ventilation.6.4 Where insulation is to be installed beneath floors overcrawl spaces or on crawl

24、space walls, cover the ground surfacewith a vapor retarder.6.5 Provide proper crawl space ventilation in accordancewith local building requirements or practices, such as the ICCInternational Residential Code.6.6 Inspect attic floors for openings that might permitentrance of air from conditioned spac

25、es below. Do not installinsulation in such areas until the owner has been informed andhas certified that these conditions have been corrected.7. Installation Procedures7.1 General:7.1.1 Handle the insulation material in accordance with themanufacturers instructions and keep free of extraneous mate-r

26、ials. Keep materials dry, off the ground, and protected fromwater.7.1.2 It is difficult to describe every situation that will beencountered by the insulation installer. In general, however, theinstaller shall be guided by the need to reduce heat flow aroundor through obstructions and to protect mech

27、anical systems.Wherever insulation is installed in a building, it is veryimportant that it fit snugly on all sides. If the insulation is toolong for a space, cut it to the correct size. If it is too short, cuta piece to fill the void.7.1.3 Install the insulation in such a way that the thicknessspeci

28、fied by the manufacturer is met or exceeded. Avoidcompression of the insulation where ever possible. Failure toachieve the manufacturers labeled thickness will reduce theR-value.7.1.4 When a vapor retarder facing is provided with theinsulation, it can be pressure fit with no stapling or face stapled

29、or inset stapled. Both inset and face staple methods are widelyused and are acceptable procedures. Inset stapling is usuallypreferred by the wall finish trades because it allows adhesiveapplication of the wall board. Some areas require face stapling.Always check the local code requirements.7.1.4.1 P

30、osition the vapor retarder toward the winter-warmside, except in a hot, humid climate where local requirementsor practices differ regarding the placement of vapor retarders.7.1.4.2 Friction fit batts such as R13, R15, R21, R22, R30C,or R38C as well as kraft faced batts without attached staplingflang

31、es do not have to be stapled in place. The higher densityor increased glass batt width of these products helps hold themin place without a measurable loss in the moisture protection ofthe vapor retarder. Make sure the insulation facing is flush withthe face of the stud. The insulation shall fit snug

32、ly at the sidesand ends.7.1.4.3 When inset stapling, gently press the insulation atthe sides of the framing cavity, usually about34 in. (19 mm),until the outside of the flange is flush with the face of theframing. When inset stapling between inclined or verticalframing members, as in cathedral ceili

33、ngs or walls, startstapling at the top and work down. Use enough staples to holdthe insulation firmly in place and avoid gaps or fishmouthsbetween flanges and framing.7.1.4.4 When face stapling, place the insulation betweenframing members and check to be sure it fits the cavity at bothends. With fac

34、ing material flush with the face of the framing,the flanges will overlap the framing. Staple the flanges to theface of the framing, using enough staples to hold the insulationfirmly in place and avoid gaps and fishmouths. The flange ofthe faced insulation placed in the next cavity will overlap thepr

35、eviously stapled flange. When more than one batt is used,pieces shall be snugly butted.7.1.5 Building insulations faced with kraft or standard foilhaving a flame spread index greater than 25 shall never be leftexposed as stated on the facing of the product. The facing shallbe covered and in substant

36、ial contact with an approved ceiling,C1320 10 (2016)2wall, or floor construction material as required by the buildingcodes. When supplied with stapling flanges inset and facestapling of these products are acceptable procedures. Alter-nately a separate vapor retarder installed over the unfaced battso

37、r blanket attached directly to the framing member in thelocation described in 7.1.4.1 is acceptable.7.1.5.1 Install the vapor retarder either parallel or perpen-dicular to framing members.7.1.5.2 In installations where there is a light stress on thevapor retarder, attach to wood framing with staples

38、 oradhesive, and to steel framing with adhesive or double sidedtape.7.1.5.3 In installations where there is a significant load onthe vapor retarder due to application conditions, support withfurring strips and screws or strapping. Consult the vaporretarder supplier for further instructions in such c

39、ases.7.1.5.4 Overlap the adjacent runs by at least one inch(25mm).7.1.5.5 When required by building codes or architecturalspecifications tape over overlap seams.7.1.6 Maintain a 3-in. (75-mm) minimum air space aroundmotors, fans, blowers, heaters, other heat-producing devices,flues and chimneys, as

40、specified by NFPA-31, NFPA-54, andNFPA-211.7.1.7 Maintain a 3-in. (75-mm) minimum air space aroundall sides of recessed lighting fixtures, unless such fixtures areapproved for installation in direct contact with insulation, ICrated, as specified in NFPA-70. This includes fixture wiringcompartments a

41、nd ballasts, and other heat-producing devices.Do not cover open areas above these devices; allow free aircirculation, unless they are specifically approved for operationwhen covered with thermal insulation.Allow devices that havethe potential to require periodic servicing to remain accessibleafter t

42、he insulation is installed.7.2 Walls:7.2.1 Carefully fill any small spaces remaining aroundwindows, doors, or wall cavity obstructions with insulation.Patch the vapor retarder with vapor retarder tape where it hasbeen interrupted in these areas, including any remaining fishmouths or gaps between fla

43、nges and framing.7.2.2 Caulk, gasket, or otherwise seal around all otherpenetrations of the interior wall, including plumbing, electrical,heat registers, and grills.7.2.3 Insulate junction boxes for wall switches and conve-nience outlets at outside walls between the rear of the box andthe sheathing.

44、 Place insulation behind the junction box, and ifnecessary, cut insulation to fit snugly around it. Where electri-cal wiring passes through a stud cavity and is located close tothe inside wall surface, insulation shall be pressed behind thewiring. When the wiring is in the center of the cavity, eith

45、ermake a shallow cut in the insulation to allow the wiring to passthrough the insulation or split the insulation lengthwise andsandwiched the wiring within.7.2.4 Place insulation between the piping in exterior wallsand the exterior wall sheathing. Sidewalls where plumbingfixtures are to be placed sh

46、all be insulated before the fixturesare installed. To guard against pipes freezing, insulation shallnever be placed between piping and the warm side of the wall.7.3 Attics, Ceilings, and Floors:7.3.1 When installing insulation around trusses or crossbracing of ceiling or floor joists, care shall be

47、taken to ensurethat the insulation material is of the proper width, fits tightlyaround these obstructions, and that there are no gaps in theinsulation.7.3.2 Use only full width (typically 16 or 24 in. wide) battsor blankets when insulating between attic trusses and ceilingjoists below open attic spa

48、ces. When insulating with twolayers, the first layer of insulation shall be at least the sameheight as the bottom structural member.Apply the second layercrosswise to the joists. For single layer applications, useinsulation thicker than the bottom structural member and makesure the tops of adjacent

49、batts or blankets meet and cover thestructural members where unobstructed.7.3.3 Install floor insulation between floor joists to fit snuglyin the joist areas in contact with the floor and support with suchthings as wire fasteners, screening, or nylon mesh held in placeby stapling or nailing.7.3.4 Install insulation around air vents in a manner that willensure free movement of air through the vents into the attic orcrawl space.7.3.5 Fit the attic side of access doors or panels with aninsulation batt (or equivalent material) except where there is aretractable lad
