Longitudinal joints sealed withmetal fasteners or factory-applied SSL tape. Transverse joints secured with metal fasteners or with butt tape supplied withthe product. Annular space between pipe covering and periphery of opening to be min 0 in. (0 mm, point contact) to max1-7/8 in. (48 mm).

See Pipe and Equipment Covering-Materials (BRGU) category in the Building Materials Directoryfor names of manufacturers. Any pipe covering material meeting the above specifications andbearing the UL Classification Marking with a Flame Spread Index of 25 or less and a SmokeDeveloped Index of 50 or less may be used.

The hourly T Rating is 1-1/4 Hr for pipe coverings of nom 1 in. and 1-1/2 in. (25 mm and 38 mm) thick for 2 Hrrated assemblies. The hourly T Rating is 1-1/2 Hr for pipe coverings of nom 2 in. (51 mm) thick for 2 Hr ratedassemblies. The hourly T Rating is 1/2 Hr for pipe coverings of nom 1 in. and 1-1/2 in. (25 mm and 38 mm)thick for 1 Hr rated assemblies. The hourly T Rating is 3/4 Hr for pipe coverings of nom 2 in. (51 mm) thick for 1Hr rated assemblies.

4. Fill, Void or Cavity Material* - Caulk or Sealant — Min 5/8 in. (16 mm) thickness of caulk applied within annulus, flushwith both surfaces of wall. Min 1/4 in. (6 mm) diam bead of caulk applied to gypsum board/pipe covering interface at pointcontact location on both sides of wall.

1. Wall Assembly — The 1 and 2 hr fire rated gypsum wallboard/stud wall assembly shall be constructed of the materialsand in the manner specified in the individual U400 Series Wall and Partition Designs in the UL Fire Resistance Directory andshall include the following construction features:

A. Studs — Wall framing shall consist of steel channel studs to be min 3-1/2 in. (89 mm) wide andspaced max 24 in. (610 mm) OC. Additional 3-1/2 in. (89 mm) wide steel studs shall be used tocompletely frame opening.

B. Gypsum Board* — Thickness, type, number of layers and fasteners as required in the individualWall and Partition Design. Max size of opening to be 1216 sq in. (189 cm2) with a max dimensionof 38 in. (965 mm).

The hourly F Rating of the firestop system is equal to the hourly fire rating of the wallassembly in which it is installed.

2. Through-Penetrant — Nom 36 by 30 (914 by 762 mm) (or smaller) No. 24 gauge (or heavier) galv steel duct to beinstalled either concentrically or eccentrically within the firestop system. An annular space of min 0 in. (0 mm, point contact)to max 2 in. (51 mm) is required within the firestop system. Steel duct to be rigidly supported on both sides of floor or wallassembly.


A. Packing Material (Optional) — Polyethylene backer rod, mineral wool batt insulation orfiberglass batt insulation friction-fit into annular space for 2 hr rated wall assemblies only. Packingmaterial to be recessed from both surfaces of wall to accommodate the required thickness of fillmaterial (Item 3B).

B. Fill, Void or Cavity Material* — Caulk or Sealant — Min 5/8 in. (16 mm) thickness of fillmaterial applied within annulus, flush with both surfaces of wall assembly. At the point contactlocation between duct and wallboard, a min 1/4 in. (6 mm) diam bead of sealant shall be applied atthe wallboard/duct interface on both surfaces of wall assembly.

3M COMPANY — CP-25 WB+ or FB-3000 WT
