Abstract:
1. A head-of-wall firestopping construction positionable in a head-of-wall area defined between a ceiling thereabove and a wall construction therebelow wherein the ceiling includes a fluted ceiling deck which defines at least one ceiling runner channel therein with recessed areas defined therein facing downwardly toward the head-of-wall area therebelow with the at least one ceiling runner channel including an upper recess panel extending generally horizontally and including a first recess side panel engaging the upper recess panel and extending downwardly and outwardly therefrom and including a second recess side panel engaging the upper recess panel at a position spatially disposed from the first recess side panel and extending downwardly and outwardly from the upper recess panel in a direction extending away from the first recess side panel, the head-of-wall firestopping construction also being for use with a wall construction extending generally vertically and positioned below the head-of-wall area which includes a plurality of wall studs with a first gypsum board construction attached thereto and a second gypsum board construction attached thereto at a position spatially disposed from the first gypsum board construction, said head-of-wall firestopping construction including: A. a first insulation member of fire insulating material positioned extending into one of said recessed areas defined in the ceiling and being in frictional engagement with respect to the fluted ceiling deck and extending downwardly therefrom into the head-of-wall area, said first insulation member comprising: B. a second insulation member of fire insulating material positioned extending into one of said recessed areas defined in the ceiling and being in frictional engagement with respect to the fluted ceiling deck and extending downwardly therefrom into the head-of-wall area, said second insulation member comprising: C. a first cover attached to said first insulation member and positioned extending at least partially across said first upper insulation exterior surface and at least partially across said first lower insulation exterior surface for enhancing firestopping of said first insulation member; and D. a second cover attached to said second insulation member and positioned extending at least partially across said second upper insulation exterior surface and at least partially across said second lower insulation exterior surface for enhancing firestopping of said second insulation member.
