Smoke and sound barrier for a building joint system

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).

Method of firestopping a through-penetration using a fusible inorganic blended-fiber web

Herein is disclosed a sleeve system and methods of using the system. The system uses an elongated open-ended sleeve, and mounting plate parts which mate with each other to form a mounting plate and which are securable to each other and to a wall. The mounting plate thus formed comprises a collar which, when the mounting plates parts are secured together, presses against portions of the outer surface of the sleeve to hold the sleeve in place.
