This specification covers the composition and physical properties of nodulated mineral fiber thermal insulation for use in attics or enclosed spaces in housing and other framed buildings. The nodulated mineral fiber thermal insulation shall be of the following types: Type I and Type II. The basic material shall be fibers made from mineral substances such as rock, slag, or glass processed from the molten state into an incombustible fibrous form. The fibers shall be mechanically processed into nodules, and are permitted to be treated to provide improved processing and handling characteristics suitable for installation by pouring or pneumatic applications. The following test methods shall be performed for purposes of initial material product requirements: thermal resistance; critical radiant flux; combustion characteristics; water vapor sorption; odor emission; corrosiveness; and fungi resistance.

1.1 This specification covers the composition and physical properties of nodulated mineral fiber thermal insulation for use in attics or enclosed spaces in housing and other framed buildings.

1.2 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.

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.
