Abstract
Gravity-laid inorganic fiber webs and methods of making and using are disclosed. The gravity-laying process comprises mechanically separating inorganic fibers and collecting the fibers as a web, and may comprise blending of multiple types of inorganic fibers and/or blending of inorganic particulate additives with the fibers.
Claims22
A method of enhancing the fire-protecting of a through-penetrating opening in a partition, the method comprising:
- inserting at least one article comprising a gravity-laid inorganic fiber web at least partially into the through-penetrating opening.
A method of enhancing the fire-protecting of an elongated object or a collection of elongated generally-aligned objects, the method comprising:
- wrapping at least one an article comprising a gravity-laid inorganic fiber web at least partially circumferentially around the object or collection of objects, along at least a portion of the elongated length of the object or collection of objects.
