Standard Guide for Development of Coverage Charts for Loose-Fill Thermal Building Insulations
SIGNIFICANCE AND USE
5.1 Coverage charts list the required installed and product in-service parameters of minimum thickness, maximum net coverage per package, and minimum mass per unit area to achieve each listed thermal performance (R-value) level. Chart information corresponds to numerous standard R-value levels representing common building codes, industry standards, or legislated requirements (see example in the Appendix X1) and therefore additional chart columns may be required, that is, number of packages per 1 000 ft2 (100m2), and initial installed thickness.
5.2 This guide applies to coverage charts for installations in open, horizontal attic floor spaces. Chart maximum net coverages are based upon net floor area; framing area deducted. Sloped ceilings, HVAC equipment and ductwork, and other factors can significantly influence product coverage and are to be considered by the manufacturer.
SCOPE
1.1 This guide provides information to manufacturers for the development of a loose-fill thermal insulation product coverage chart. This guide is limited to developing a coverage chart from density versus thickness, apparent thermal conductivity versus density, and thickness versus area mass relationships obtained through product testing.
1.2 This guide applies to a wide variety of loose-fill thermal insulation products including mineral fiber (Specification C764), or cellulosic fiber (Specification C739) materials; granular types including vermiculite (Specification C516) and perlite (Specification C549); pelletized products; and any other insulation materials that are installed pneumatically or poured in place.
1.3 Coverage charts for loose-fill insulation products are required by regulation under the United States Federal Trade Commission’s 16 CFR Part 460. Other countries or local governing agencies may have coverage chart requirements in addition to, or that differ from, those presented in this guide; see the Appendix for examples.
1.4 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.
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

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
