Designation:C 1158 05Standard Practice forInstallation and Use of Radiant Barrier Systems(RBS)inBuilding Construction1This standard is issued under the fixed designation C 1158;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.1.Scope1.1 This standard has been prepared for use by the designer,specifier,and installer of RBS(radiant barrier systems)for usein building construction.The scope is limited to recommenda-tions relative to the use and installation of RBS including asurface(s)normally having a far-infrared emittance of 0.12orless,such as metallic foil or metallic deposits unmounted ormounted on substrates.Some examples that this standard isintended to address include:(1)low emittance surfaces invented or unvented building envelope cavities intended toretard radiant transfer across the airspace;(2)low emittancesurfaces at interior building surfaces intended to retard radianttransfer to or from building inhabitants;and(3)low emittancesurfaces at interior building surfaces intended to reduce radianttransfer to or from radiant heating or cooling systems.See Figs.1-4 for typical examples of use.1.2 This standard covers the installation process from pre-installation inspection through post-installation procedure.Itdoes not cover the production of the radiant barrier materials.(See Specification C 1313.)1.3 This standard is not intended to replace the manufactur-ers installation instructions,but shall be used in conjunctionwith such instructions.This practice is not intended to super-cede local,state,or federal codes.1.4 This standard assumes that the installer possesses a goodworking knowledge of the application codes and regulations,safety practices,tools,equipment,and methods necessary forthe installation of radiant barrier materials.It also assumes thatthe installer understands the fundamentals of building con-struction that affect the installation of RBS.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.For specificprecautionary statements,see Sections 5 and 7.1.6 When the installation or use of radiant barrier materials,accessories and systems,may pose safety or health problems,the manufacturer shall provide the user appropriate currentinformation regarding any known problems associated with therecommended use of the companys products and shall alsorecommend protective measures to be employed in their safeutilization.The user shall establish appropriate safety andhealth practices and determine the applicability of regulatoryrequirements prior to use.2.Referenced Documents2.1 ASTM Standards:3C 168 Terminology Relating to Thermal InsulationC 1313 Specification for Sheet Radiant Barriers for Build-ing Construction Applications2.2NFPA Standards:4NFPA 54 National Fuel Gas CodeNFPA 211 Standard for Chimneys,Fireplaces and Vents2.3Other Documents:CPSC Product Safety Fact Sheet No.18“The Home Elec-trical System”53.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this standard practicerefer to Terminology C 168.3.2 Definitions of Terms Specific to This Standard:3.2.1 applicatorthe person or persons who apply radiantbarrier materials in buildings.3.2.2 conditioned spaceany space in a building that isserved by a heating or cooling system.3.2.3 open air spacea vented building cavity(for ex-ample,a vented attic)or a large conditioned or unconditionedbuilding space.NOTE1A large building space is defined as a one whose minimum1This practice is under the jurisdiction of ASTM Committee C16 on ThermalInsulation and is the direct responsibility of Subcommittee C16.21 on ReflectiveInsulation.Current edition approved Nov.1,2005.Published November 2005.Originallyapproved in 1990.Last previous edition approved in 2001 as C 1158 01.2The as manufactured emittance of a radiant barrier product should be stated onthe label.3For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.4Available from National Fire Protection Association,Batterymarch Park,Quincy,MA 02269.5Available from U.S.Consumer Product Safety Commission,Washington,DC20207.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.Copyright by ASTM Intl(all rights reserved);Thu Apr 16 08:29:09 EDT 2009Downloaded/printed byLaurentian University pursuant to License Agreement.No further reproductions authorized.dimension exceeds two feet.3.2.4 radiant barrier sy
