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.

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. Specific hazards that can result from improper installation 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.

This practice provides recommendations for the installation of IRCCS materials in a safe and effective manner. Actual conditions in existing buildings will vary greatly.In some cases additional care should be taken to ensure safe and effective installation.

This practice presents requirements that are general in nature and considered practical. They are not intended as specific recommendations. The user should consult the manufacturer for recommended application methods.

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 is limited to recommendations 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. 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.

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 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 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.

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.
