4. Firestop System — The firestop system shall consist of the following:

A. Packing Material — Min 76 mm (3 in.) thickness of min 64 kg/m³ (4 pcf) mineral wool batt insulation compressed and tightly packed into opening. Packing material recessed from top surface of floor or both surfaces of wall or precast concrete units. When steel sleeve projects from top of floor or from both sides of wall, the thickness of mineral wool batt packing material should be increased by an amount equal to the distance that the sleeve extends past the floor or wall surface. When 25 mm (1 in.) of fill material (Item 4B) is used, mineral wool packing material thickness may be reduced to 38 mm (1-1/2 in.).

B. Fill, Void or Cavity Material* — Sealant — Min 12.7 mm (1/2 in.) thickness of fill material applied within annulus, flush with top surface of floor assembly or top edge of steel sleeve. In walls, min 12.7 mm (1/2 in.) thickness of fill material applied within annulus flush with both surfaces of wall assembly or both ends of steel sleeve. When thickness of concrete is less than 114 mm (4-1/2 in.), min 25 mm (1 in.) depth of sealant applied within annulus flush with top of floor/top edge of sleeve or both sides of wall/ ends of sleeve. In floors constructed of hollow-core precast concrete units, fill material installed symmetrically on both surface of floor. At point contact location, apply min 6.4 mm (1/4 in.) diam bead of fill material at cable/concrete or cable/steel sleeve interface on top surface of floor or on both surfaces of wall or precast concrete units.
