3、res for the installation ofcellulosic and mineral fiber loose-fill insulation in ceilings,attics, and floor and wall cavities of new or existing housingand other framed buildings.1.2 This practice applies only to the installation of dryloose-fill thermal insulation consisting of cellulosic materials
4、or mineral fiber by pneumatic or pouring application.1.3 This practice covers the installation process from pre-installation inspection through post-installation procedure. Itdoes not cover the production of the insulation materials.1.4 This practice is not intended to replace the manufactur-ers ins

This practice is not intended to super-sede local, state, or federal codes.1.5 This practice assumes that the installer possesses a goodworking knowledge of the applicable codes and regulations,safety practices, tools, e
6、quipment, and methods necessary forthe installation of thermal insulation materials. It also assumesthat the installer understands the fundamentals of residentialconstruction that affect the installation of insulation.1.6 The values stated in inch-pound units are to be regardedas standard. The value

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 Improper installation of insulation can reduce its ther-mal effectiveness, cau
21、se fire risks and other unsafe conditions,and promote deterioration for the structure in which it isinstalled. Specific hazards that can result from improperinstallation include fires caused by (1) heat build-up in recessedlighting fixtures; (2) deterioration or failure of electrical wiringcomponent
22、s; (3) heat build-up resulting from overcurrentprotection devices incorrectly matched to wiring; or (4) dete-rioration in wood structures and paint failure due to moistureaccumulation.4.3 This practice provides general procedures that will helpensure the installation of insulation in a safe and effe
23、ctivemanner. It must be noted that actual conditions in existingbuildings vary greatly, and in some cases substantial additionalcare and precaution must be taken to ensure effective and safeinstallation.5. Safety Precautions5.1 All pneumatic equipment shall be operated in accor-dance with the recomm
24、ended operating and safety proceduresof the equipment manufacturer and the insulation manufac-turer.5.2 The installer shall wear proper clothing and equipmentas recommended by the insulation manufacturer. If in doubt ofthe effects of the insulation, wear protective clothing, gloves,eye and breathing
25、 protection.NOTE 1For breathing protection use a NIOSH approved N95 orhigher disposable or reusable particulate respirator.5.3 In areas where insulation will be installed, componentsof the electrical system shall be in good condition. If theelectrical system is faulty, proper inspection and repair m
26、ust benone.NOTE 2The Consumer Product Safety Commission6has identified thefollowing signs of potential electrical deficiencies: Lights dimming, fusesblowing, circuit breakers tripping frequently, electrical sparks and glowingfrom receptacles, lights flickering, and coverplates on switches and outlet
27、sthat are warm or hot to the touch.6. Pre-Installation Preparation6.1 In the areas where insulation will be installed, theinstaller shall locate and plan for subsequent blocking aroundrecessed lighting fixtures, motors, fans, blowers, heaters, flues,chimneys, and other heat-producing electrical or m
28、echanicaldevices.6.1.1 Install blocking, such as wood, metal, or unfacedmineral wool batts, securely fastened in place around allheat-producing devices to exclude loose fill insulation andpermanently maintain the clearances specified in 6.1.2 and6.1.3, or the exception in 6.1.5. Install all required
29、 blocking atleast as high as the height of the finished insulation and in amanner that ensures that all devices that require maintenance orservicing remain accessible after the insulation is installed.6.1.2 Install blocking to provide a 3-in. (75-mm) minimumclearance around all sides of recessed lig
30、hting fixtures, unlesssuch fixtures are approved for installation in direct contact withinsulation (IC rated), including fixture wiring compartmentsand ballasts, and other heat-producing devices not covered in6.1.3. The open area above these devices must not be covered,in order to allow free air cir
31、culation unless they are specificallyapproved devices for operation when covered with thermalinsulation (see 410-66, NFPA 70, National Electric Code).6.1.3 Do not place insulation in air spaces surroundingmetal flues, chimneys or fireplaces. Provide the minimumclearances specified in NFPA 31, NFPA 5
32、4 or NFPA 211 or asrequired by local building codes.6.1.4 Install depth markers to measure the insulation depth.The markers shall have lines labeled in inches (millimetres).The numbers shall not be less than 1 in. (25 mm) in height. Themarkers shall be installed at a minimum rate of one marker forev
33、ery 300 ft2(28 m2) throughout the attic space. The markersshall be attached to the trusses or joists and marked with aminimum initial installed thickness and the markers shall facethe attic access opening.6.1.5 Inspect the roof, walls, ceilings, and attic floors toidentify areas where previous or ex
34、isting moisture problem hascaused paint peeling, warpage, stain, visible fungus growth,rotting, or other structural damage. Notify the owner to correctthese conditions before installing insulation.6.1.6 The installer shall block all openings in ceilings,floors, and sidewalls through which it is poss
35、ible for theinsulating material to escape. Block all wall cavities that openinto a basement or crawl space before wall insulation isinstalled.6CPSC Product Safety Fact Sheet No. 518, “Guide to Home Electric Wiring,”available from the Consumer Product Safety Commission, 4330 East West HighwayBethesda
36、, MD 20814.C1015 1726.1.7 Proper attic ventilation, air sealing and vapor retardersshall be provided before installation in accordance with build-ing requirements, designers specifications, and applicablecodes.NOTE 3The International Residence Code, Section R806.2 states thefollowing attic ventilati
37、on requirements: The total net free ventilating areashall not be less than 1 to 150 of the area of the space ventilated exceptthat the total area is permitted to be reduced to 1 300, provided at least 50% and not more than 80 % of the required ventilating area is provided byventilators located in th
38、e upper portion of the space to be ventilated at least3 ft (914 mm) above the eave or cornice vents with the balance of therequired ventilation provided by eave or cornice vents. As an alternative,the net free cross-ventalation area may be reduced to 1 to 300 when avapor barrier having a transmissio
39、n rate not exceeding 1 perm (57.4 mg/sm2Pa) is installed on the warm side of the ceiling.When the attic has soffit vents at the eaves, install rigidblocking to restrain loose-fill insulation from clogging thevents, thus restricting attic ventilation. Blocking shall beinstalled to ensure free movemen
40、t of air through soffit ventsinto the attic.7. Procedure7.1 Installation:7.1.1 The insulation material shall be handled in accordancewith manufacturers instructions and should be kept free ofextraneous materials. Keep the materials dry and do not placein contact with the ground or other sources of w
41、ater.7.1.2 Apply the insulation uniformly covering all areas. Toattain the required R-value, install at least the minimumthickness and minimum square-foot weight in acordance withthe coverage chart supplied by the manufacturer.7.1.3 Fill enclosed cavities to rejection of the material toensure that c
42、avity is free of voids and that the proper amountis installed in accordance with the manufacturers coveragechart.7.1.4 For pneumatic installation, use only equipment com-patible with the insulation material, and operate the equipmentin accordance with the manufacturers instructions.7.1.5 In pouring
43、applications, install insulation in accor-dance with the manufacturers recommended coverage.7.2 Post-Installation:7.2.1 Inspect the coverage and depth of the insulation. Fillall pockets and voids in the insulation. Level insulation in amanner that will not damage wiring or any other items. Turnoff t
44、he electric power and clear all electric wall outlet boxesand switch boxes of any insulation material. Check all bafflesand vents for insulation accumulation. Remove all temporaryblockings that were installed over vent openings in attics.7.2.2 The installer must provide a signed and dated state-ment
45、 describing the insulation installed, stating thickness,coverage area, R-value, and number of bags used or poundsinstalled per FTC Rule 16 CFR 460.8.
