Abstract
Monolithic gravity-laid inorganic fiber webs that are greater than about 5 cm in thickness are disclosed. Methods of making and using such webs are also disclosed. The gravity-laying process comprises mechanically separating inorganic fibers and collecting the fibers as a monolithic thick web, and may comprise blending of multiple types of inorganic fibers and/or blending of inorganic particulate additives with the fibers.
