Beschreibung
Zusammenfassung:	An article for fire protecting a duct includes a first layer of a first material including a noncombustible fibrous material and a second layer of a second material including an intumescent material. The first layer is adjacent the second layer. The article is non-self-supporting and has an initial thickness of less than about three inches when in a first application condition, and an expanded thickness when in a second heated condition. The expanded thickness is greater than the initial thickness. At the expanded thickness, the article meets Section 5.5 of AC101 Acceptance Criteria for Grease Duct Enclosure Assemblies, as specified in April 2001 by the International Council of Building Officials (ICBO-ES).
