    Significance and Use

    4.1 This practice recognizes that effectiveness, safety, and durability of an IRCCS depends not only on the quality of the materials, but also on the proper installation.

    4.2 Improper installation of an IRCCS will reduce its thermal effectiveness, cause fire risks and other unsafe conditions, and promote deterioration of the structure in which it is installed. Improper installation has the potential to create specific hazards that include: heat buildup in recessed lighting fixtures, deterioration of failure of electrical wiring components, and deterioration of wood structures and paint failure due to moisture accumulation.

    4.3 This practice provides directions for the installation of IRCCS materials in a safe and effective manner. Actual conditions in existing buildings will vary greatly.

    4.4 Requirements that are presented in this practice are both general and specific in nature. They are not intended as specific instructions unless so indicated. The user shall consult the manufacturer for application and installation methods.

    1. Scope

    1.1 This practice has been prepared for use by the designer, specifier, and applicator of IRCCS (Interior Radiation Control Coating Systems) for use in building construction. The scope contains instructions related to the use and installation of IRCCS, including a surface(s) having a far-infrared emittance of 0.25 or less that is sprayed or painted.2 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 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 heating or cooling systems. See Fig. 1 and Fig. 2 for typical applications.

    Typical Residential Use
    Note 1Apply IRCCS to cover the exposed roof deck area. The low-emittance surface of the IRCCS must face the interior of the attic.
    FIG. 1 Typical Residential Use
    Typical Industrial, Commercial, and Agricultural Use
    Note 1Apply the IRCCS to cover the entire interior surface area. The low-emittance surface of the IRCCS must face the interior of the bldg.
    FIG. 2 Typical Industrial, Commercial, and Agricultural Use

    1.2 This practice covers the installation process from pre-installation inspection through post-installation. It does not cover the production of the Interior Radiation Control Coating Materials.

    1.3 This practice is not intended to replace the manufacturer's installation instructions, but it shall be used in conjunction with such instructions. This practice is not intended to supersede local, state, or federal codes.

    1.4 This practice 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 Interior Coating Materials. It also assumes that the installer understands the fundamentals of building construction that affect the installation of an IRCCS.

    1.5 When the installation or use of Interior Radiation Control Coating Materials, accessories, and systems pose safety or health problems, the manufacturer shall provide the user appropriate current information regarding any known problems associated with the intended use of the products and shall also provide direction on protective measures to be employed for safe utilization. The user shall establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.

    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. Specific precautionary statements are contained in Sections 5 and 7.
