Abstract: In an embodiment of the disclosed principles, a fire barrier penetration sealer is disclosed for sealing an opening in a fire barrier, such as but not limited to a wall, at the location of penetration. The fire barrier penetration sealer may include an annular face plate having a front face and a back face. A continuous projection extends concentrically from the back face of the annular face plate. An inner intumescent strip covers the inner surface of the projection, and an outer intumescent strip covers the outer surface of the projection, such that the annular face plate and the connected continuous projection fit over the object penetrating the fire barrier when the fire barrier penetration sealer is placed over the opening in the fire barrier with its front face facing outward. In the event of a fire, the heat of the fire or hot gases will expand the intumescent materials, thereby sealing the penetration.

Abstract: A fire barrier box for placement within a fixture membrane in a fire barrier wall provides a metallic side panel box of multiple box sides, each side having a slot, and a selectively attached back panel. An intumescent liner attaches to the inner side panel walls and to the interior surface of the back panel. When a fixture is received within the side panel box, the intumescent liner, and the slots cooperatively receive fixture supply lines enabling their connection with the fixture. The selective attachment of the back panel occurs once rear access to the side panel box interior is no longer required. The completed fire barrier box attaches to the stud framing, maintaining the rating protection of the fire barrier wall.

Abstract: A fire barrier insert for placement within a framed out membrane penetration in a fire barrier wall is constructed of a central back member of a high-temperature drywall board and an attached flexible intumescent mat. The central back board is configured for placement against a drywall panel of similar configuration within the framed out membrane penetration. The flexible intumescent mat consists of separate panels, each attached to the central back board for extending along the frame members and to the outer edge of the framed out membrane penetration. A fixture cabinet is placed within the framed out membrane penetration after installation of the fire barrier insert.
