| 20110094759 | Self-adjusting firestopping sleeve apparatus with flexibly resilient supplemental constriction means - A firestopping sleeve positionable usually in walls which is self-adjusting and includes a sleeve defining an access corridor extending longitudinally therewithin with at least one firestopping pad positioned therein. The pad defines an access corridor extending therethrough for receiving wall penetrating cables which are firestopped therearound by the pad. A supplemental construction band is positioned extending around the pad for enhancing firestopping adjacent the penetrating wire for facilitating preventing the flow of heat, smoke or fire therepast. | 04-28-2011 |
| 20110011019 | Firestopping sealing means for use with gypsum wallboard in head-of-wall construction - A sealing gasket for use attached preferably to the topmost edge of gypsum board when used as construction wallboard. The gasket includes a support leg section capable of being mounted in engagement with preferably the uppermost edge of the gypsum board. The gasket includes a sealing leg extending outwardly from said leg section which includes an intumescent component to facilitate sealing between the edge of the gypsum board and the wall structure above. In one embodiment the sealing leg includes an intumescent impregnated paper material covered with a structurally enhancing layer. An adhesive layer can be included to attach the gasket to the gypsum wallboard. The sealing leg is in this embodiment is planar and will extend upwardly and inwardly over the upper edge of the gypsum board at an obtuse angle with respect to the support leg for sealing thereabove in the head-of-wall area. An alternative embodiment is extruded and has a sealing leg having an “A” or “P” profile with the lower portion adhered to the gypsum board. | 01-20-2011 |
