This specification covers the composition and physical properties of spray-applied cellulosic fiber stabilized thermal insulation applied to open or closed ceiling spaces, regardless of slope. The basic material shall be recycled cellulosic fiber made from selected paper or paperboard stock. Stabilized cellulosic fiber thermal insulation is produced by the addition of adhesive(s) to loose-fill cellulosic fiber insulation. Additives are introduced to provide properties such as flame resistance, processing and handling characteristics. An adhesive is added to the insulation product to resist long-term settling of the insulation after installation and curing. Different test methods shall be performed in order to determine the following properties of thermal insulation: density, corrosiveness, critical radiant flux, fungi resistance, water vapor sorption, odor emission, smoldering combustion, thermal resistance, flame resistance permanency, shrinkage, and settling.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 This specification covers the composition and physical properties of spray-applied cellulosic fiber stabilized thermal insulation applied to open or closed ceiling spaces, regardless of slope, where temperatures range from –49 to 194°F (–45 to 90°C).
1.2 Stabilized cellulosic fiber thermal insulation is produced by the addition of adhesive(s) to loose-fill cellulosic fiber insulation. The adhesive(s) are either added to the insulation at time of manufacture and, if necessary, activated by the addition of water when installed or the adhesive(s) are otherwise added to the insulation at the time of installation.
1.3 This is a material specification that is not intended to deal with methods of application that are supplied by the manufacturer.
1.4 The values stated in inch-pound units are to be regarded as standard. The SI units given in parentheses are for information only.
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 and health practices and determine the applicability of regulatory limitations prior to use.
