1.1 This specification covers the classification, composition, and physical properties of flexible glass fiber insulation for use as interior surface of walls and roofs of metal buildings.
1.2 The basic insulation blanket is designed to be post-processed by a laminating process that applies an adhesive bonded facing to provide the interior finish and vapor retarder requirements for the building envelope.
1.3 The thermal values measured in accordance with this specification for both pre-processed and post-processed insulation are for the insulation only and do not include the effects of air-film surface resistance, changes in mean temperature, or compression of insulation at the framing members of the building, through metal conductance of fasteners and other parallel heat-transfer paths due to design or installation techniques.
1.4 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.
