About this detail

An audio-visual box is mounted on wood or metal backing within a framed partition wall, dimensioned relative to the conference table centerline and finish floor. A metallic pipe or conduit penetrates the wall assembly, which consists of a one-hour or two-hour partition with gypsum board layers as scheduled. The wall opening is packed tightly with a minimum four pounds per cubic foot mineral wool batt insulation equal in width to the wall thickness. An eighth-inch minimum fire sealant completely covers the mineral wool and overlaps the wall surface and penetrating pipes or conduits by a half-inch.
