A fire-protection apparatus contains a housing with a passage, and an insert containing a plurality of sections made of a flexible material.

Air, acoustic and/or fire sealing sleeve insert and air, acoustic and/or fire sealing device

A method includes coupling a platform to a sheet metal having alternating peaks and Valleys. The platform includes a block-out component configured to conform to a valley of the sheet metal. The method further includes coupling a lead-sleeve to a mounting region of the platform. The method further includes pouring concrete around the platform and lead-sleeve, where the block-out component blocks a flow of the concrete from below the platform. The method also includes inserting a cutting tool through the lead-sleeve to remove one or more portions of the sheet metal to form a through-penetration.

Method for firestop through-penetrations

An air, acoustic and/or fire sealing device comprising an air, acoustic and/or fire sealing insert body comprising molded foam material, the body having a first end and a second end and a bulk continuous with the first end and the second end; wherein the body has an outer diameter, and the body is adapted to allow one or more pipes, fibers and/or cables to pass through the first and second ends and the bulk; and, a flexible hollow sleeve having an inner diameter, a first open end and a second open end, the ends being axially arranged; wherein the outer diameter of the air, acoustic and/or fire sealing insert body is greater than, equal to, or less than, the inner diameter of the flexible hollow sleeve; and, the air, acoustic and/or fire sealing insert body is arranged in the sleeve, is disclosed.
