64 Designation: C Standard Practice for Installation and Use of Radiant Barrier Systems (RBS) in Building Construction 1 This standard is issued under the fixed designation C 1158; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (~) indicates an editorial change since the last revision or reapproval. 1 Scope 1.1 This standard has been prepared for use by the designer, specifier, and installer of RBS (radiant barrier systems) for use in building construction. The scope is limited to recommendations relative to the use and installation of RBS including a surface(s) normally having a air-infrared emittance of 0.12 or less, such as metallic foil or metallic deposits unmounted or mounted on substrates. Some examples that this standard is intended to address Include: (1) low emittance surfaces in vented building envelope cavities intended to retard radiant transfer across the vented airspace; (2) low emittance surfaces at interior building surfaces intended to retard radiant transfer to or from building inhabitants; and (3) low emittance surfaces at interior building surfaces intended to reduce radiant transfer to or from radiant heating or cooling systems. See Figs. 1, 2, 3. and 4 for typical examples of use. 1.2 This standard covers the installation process from pre-installation inspection through post-installation procedure. It does not cover the production of the radiant barrier materials. 1.3 This standard is not intended to replace the manufacturer s installation instructions, but shall be used in conjunction with such instructions. This practice is not intended to supercede local, state, or federal codes. 1.4 This standard assumes that the installer possesses a good working knowledge of the application codes and regulations, safety practices, tools, equipment, and methods necessary for the installation of radiant barrier materials. It also assumes that the installer understands the fundamentals of building construction that affect the installation of RBS. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Sections 5 and 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 current information regarding any known problems associated with the recommended use of the company s This practice is under the jurisdiction of ASTM Committee C-l6 on Thermal insulation and is the direct responsibility of Subcommittee C16.21 on Reflective insulation Current edition approved March 10, Published June Originally - publish as C (~. Last previous edition C The as manufactured emittance of a radiant barrier product should be stated in the label products and shall also recommend protective measures to be employed in their safe utilization. The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use. 2.

NOTE 1 A large building space is defined as a one whose minimum dimension exceeds two feet owner the person, partnership, corporation, agency, or other entity who owns the building in which the RBS is to be installed whether such ownership is by virtue of deed, contract, or any other instrument for acquiring legal title under the laws of the state in which the building is located radiant barrier system (RBS) a building construc- 3 Annual Book of ASTM Standards, Vol Annual Book of ASTM Standards, vol Available from National Fire Protection Association, Batterymarch Park, Quinc), MA Available from U.S. Consumer Product Safety Commission, washington, DC ASTM C Standard Practice for Installation of Radiant Barrier Systems (RBS) in Building Construction

66 HEAT SHIELD PERFORMS BETTER THAN OTHER RADIANT BARRIERS 1. TECNOLOGICAL SUPERIORITY OF CREATING FIRE RETARDANT PE WEAVE AND ADHESIVE LAYERS, GLOBALLY ACCLAIMED - BEST. 2. FLEXIBLE & FOLDABLE! TO MAKE RETRACTABLE CURTAINS 3. EXCELLENT ANTI-TEAR PROPERTIES MAKES INSTALLATION EASY 4. VERY HIGH DUARABILITY & INSULATING PEFORMANCE 5. HIGHLY ECONOMIC - VALUE FOR MONEY FOR END USERS
