ASTM C1743-12

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation:C1743–10 Designation:C1743–12
Standard Practice for
Installation and Use of Radiant Barrier Systems (RBS) in
1
Residential Building Construction
This standard is issued under the fixed designation C1743; 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 practice has been prepared for use by the designer, specifier, builder, and the installer of radiant barrier systems (RBS)
for use in (multi- and single-family) residential building construction, not otherwise restricted from use. The scope is limited to
recommendationsinstructions relative to the use and installation of RBS, including a surface(s) normally having an emittance of
0.1 or less, such as metallic foil or metallic foil deposits, mounted on substrates. Some examples that this practice is intended to
address include: (1) low-emittance surfaces in vented building envelope cavities intended to retard radiant transfer across the
airspace: (2)low-emittancesurfacesatinteriorbuildingsurfacesintendedtoretardradianttransferto,orfrom,buildinginhabitants;
and (3)low-emittancesurfaceatinteriorbuildingsurfacesintendedtoreduceradianttransferto,orfrom,radiantheatingorcooling
systems.
1.2 This practice covers the installation process from pre-installation inspection through the post-installation procedure. It does
not cover the production of the radiant barrier materials. (See Specification C1313.)
1.3 Thispracticeisnotintendedtoreplacethemanufacturer’sinstallationinstructionsbutshallbeusedinconjunctionwithsuch
instructions. This practice is not intended to supercede local, state, federal, or international codes.
1.4 This practice assumes that the installer possesses a good working knowledge of the applicable codes and regulations, safety
practices, tools, equipment, and methods necessary for installation of radiant barrier materials. It also assumes that the installer
understands the fundamentals of residential building construction that affect the installation of RBS.
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical
conversions to SI units that are provided for information only and are not considered standard.
1.6 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 7.
