METHOD OF FIRESTOPPING A THROUGH-PENETRATION USING A FUSIBLE INORGANIC BLENDED-FIBER WEB |
摘要 |
A method of firestopping a through-penetration is disclosed, which makes use of a fusible inorganic blended-fiber web. The fusible inorganic blended-fiber web can provide a fire-stopped through-penetration without the use of sealants, intumescent materials, and the like. The fusible inorganic blended-fiber web may comprise a blend of at least first, low melting inorganic fibers and second, high melting inorganic fibers. The fusible inorganic blended-fiber web comprises a bulk density of at least about 7 pounds per cubic foot (0.112 grams/cc). |
