This specification covers the standard for composition, size, dimensions, and physical properties of flexible glass blanket, ductwrap intended for use to insulate HVAC ducts. The basic materials shall be fibers manufacture from glass processed from the molten state into fibrous form. Bonded fibers formed into flexible blank rolls shall consist the insulation. Materials shall conform to physical requirements such as thermal resistance, surface burning characteristics, hot surface performance, water vapor permeance, water vapor sorption, odor emission, corrosiveness, and fungi resistance.

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. Scope

1.1 This specification covers the composition, size, dimensions, and physical properties of flexible fiber glass blanket, ductwrap, used to externally insulate HVAC ducts used for the distribution of condition air within the temperature range of 35°F (1.7°C) and 250°F (121°C).

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.

1.3 When the installation and use of thermal insulation materials, accessories, and systems may pose safety and 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.

1.4 The following safety hazards caveat pertains only to the test methods, Section 13, in this specification. 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.
