United States13.2.3 Interior Radiation Control Coating Systems(IRCCS)a building construction consisting of a low emit-tance (0.25 or less) surface bounded by an open air space. AnIRCCS is
17、used for the sole purpose of limiting heat transfer byradiation and is not specifically intended to reduce heat transferby convection or conduction.3.2.4 open air spacea vented building cavity (forexample, a vented attic) or a large conditioned or uncondi-tioned building space.3.2.5 DiscussionA larg
18、e building space is defined as onewhose minimum dimension exceeds two feet.3.2.6 ownerthe person, partnership, corporation, agency,or other entity who owns the building in which the IRCCS isto be applied whether such ownership is by virtue of deed,contract, or any other instrument for acquiring lega
19、l title underthe laws of the state in which the building is located.4. Significance and Use4.1 This practice recognizes that effectiveness, safety, anddurability of an IRCCS depends not only on the quality of thematerials, but also on the proper installation.4.2 Improper installation of an IRCCS wil
20、l reduce itsthermal effectiveness, cause fire risks and other unsafeconditions, and promote deterioration of the structure in whichit is installed. Improper installation has the potential to createspecific hazards that include: heat buildup in recessed lightingfixtures, deterioration of failure of e
21、lectrical wiringcomponents, and deterioration of wood structures and paintfailure due to moisture accumulation.4.3 This practice provides directions for the installation ofIRCCS materials in a safe and effective manner. Actualconditions in existing buildings will vary greatly.4.4 The user shall cons
22、ult the manufacturer for applicationand installation methods.5. Safety Precautions5.1 The applicator shall meet all of the requirements of themanufacturer, code, and their contract for safety.5.2 Ventilation shall be provided to ensure that mist andoverspray are immediately dispersed from the applic
23、ation area.When natural ventilation is not adequate, place OSHA ap-proved fans in windows or doors adjacent to the applicationarea to improve ventilation. Warnings shall be provided forareas where ventilation is exhausted. Ventilation of the areas ofapplication shall meet all of the requirements of
24、themanufacturer, code, and the installation contract.5.3 The instructions provided by the manufacturer shall beconsulted for all applicable handling and safety requirements.6. Pre-Installation Inspection and Preparation6.1 Inspections:6.1.1 Inspect the roof, walls, ceilings, and floors to identifyar
25、eas where previous or existing moisture problems havecaused paint peeling, warpage, stain, visible fungus growth,rotting, or other structural damage. Do not apply IRCCS insuch areas until the owner has been informed and has certifiedthese conditions have been corrected and the source(s) elimi-nated.
26、6.1.2 In areas where the IRCCS is to be applied, compo-nents of the electrical system shall be in good condition. Whenthere is reason to believe the electrical system is faulty, do notapply the IRCCS in such areas until the owner has beeninformed and qualified inspection and repair have been per-for
27、med.NOTE 1The CPSC Guide to Home Wiring Hazards has identified thefollowing signs of potential electrical deficiencies: lights dimming, fusesblowing, circuit breakers tripping frequently, electrical sparks and glowingfrom receptacles, light flickering, and cover plates on switches and outletsthat ar
28、e warm or hot to the touch. Useful safety information is alsocontained in the NFPA 54 and NFPA 211.6.1.3 In areas where an IRCCS is to be applied, theapplicator shall locate and plan the application around venti-lation openings. The applicator shall not apply the IRCCS in away that will plug or othe
29、rwise obstruct existing ventilationopenings.6.1.4 All inspections for wood grade stamps must be com-plete before application of the product.6.2 Preparations:6.2.1 All electrical wiring at or near the IRCCS applicationsurfaces shall be protected to ensure that the IRCCS materialcannot contact the ele
30、ctrical wiring system.6.2.2 Where attic ventilation is compromised by the instal-lation of an IRCCS or the subsequent application of fibrousinsulation, vent baffles shall be installed at the soffits of theattic such that attic ventilation airflows are maintained inaccordance with applicable building
31、 codes.NOTE 1Apply IRCCS to cover the exposed roof deck area includingsupport structure directly connected to the roof deck (such as purlins,rafters, and top chord of the trusses). The low-emittance surface of theIRCCS must face the interior of the attic.FIG. 1 Typical Residential UseNOTE 1Apply the
32、 IRCCS to cover the entire interior surface area. Thelow-emittance surface of the IRCCS must face the interior of the building.FIG. 2 Typical Industrial, Commercial, and Agricultural UseC1321 1526.2.3 All materials shall be mixed for at least 2 minimmediately before spraying.
