Re: fire stopping
Go to the this UL site.
If you are working off of a set of prints or specs there should be an assembly or assemblies called for.
You can put these assemblies into the seach window for the specifics.
For an example put this "w-l-3024" in and you see the following.
System No. W-L-3024
August 06, 2003
F Ratings ? 1 and 2 Hr (See Items 2 and 2A)
T Ratings ? 0, 1/2, 1 and 2 Hr (See Items 2 and 2A)
L Rating At Ambient ? Less Than 1 CFM/sq ft
L Rating At 400 F ? Less Than 1 CFM/sq ft
1. Wall Assembly ? The 1 or 2 hr fire rated gypsum board/stud wall assembly shall be constructed of the materials and in the manner specified in the individual U300 or U400 Series Wall and Partition Designs in the UL Fire Resistance Directory and shall include the following construction features:
A. Studs ? Wall framing may consist of either wood studs or steel channel studs. Wood studs to consist of nom 2 by 4 in. lumber spaced 16 in. OC. Steel studs to be min 2-1/2 in. wide and spaced max 24 in. OC.
B. Gypsum Board* ? 5/8 in. thick, 4 ft wide with square or tapered edges. The gypsum board type, thickness, number of layers, fastener type and sheet orientation shall be as specified in the individual U300 or U400 Series Design in the UL Fire Resistance Directory. Max diam of opening is 2-1/2 in.
The hourly F Rating of the firestop system is equal to the hourly fire rating of the wall assembly in which it is installed.
2. Cables ? One cable to be installed either concentrically or eccentricity within the firestop system. The annular space within the firestop system shall be a min 0 in. (point contact) to a max 1/4 in. Cable to be rigidly supported on both sides of wall assembly. The following types and sizes of cables may be used:
A. Max 200 pair No. 24 AWG (or smaller) copper conductor cable with polyvinyl chloride (PVC) jacketing and insulation. When 200 pair No. 24 AWG telephone cable is used, T Rating is 0 hr. When 50 pair No. 24 AWG telephone cable is used, T Rating is equal to the F rating of the firestop system.
B. Max 3/C No. 2/0 AWG (or smaller) aluminum conductor service entrance cable with PVC insulation and jacketing. When service entrance cable is used, the T Rating is equal to the F Rating of the firestop system.
C. Max 1/C-750 kcmil copper conductor power cable with cross-linked polyethylene (XLPE) insulation and jacketing. When 1/C-750 kcmil cable is used, the T Rating is equal to the F Rating of the firestop system.
D. Max 3/C No. 8 AWG (or smaller) PVC insulated and jacketed nonmetallic sheathed (Romex) cable. When Romex is used, the T Rating is equal to the F Rating of the firestop system.
E. Max RG59/U (or smaller) coaxial cable with fluorinated ethylene insulation and jacketing. When coaxial cable is used, the T Rating is equal to the F Rating of the firestop system.
F. Max 62.5/125 micron fiber optic cable with PVC insulation and jacketing. When fiber optic cable is used, the T Rating is equal to the F Rating of the firestop system.
G. Max 4 pair No. 24 AWG (or smaller) copper conductor data cable with Hylar insulation and jacketing. When data cable is used, the T Rating is equal to the F Rating of the firestop system.
2A. Through-Penetrating Product* ? As an alternate to Item 2, max one through-penetrating product to be installed either concentrically or eccentrically within the firestop system. Through-penetrating product to be rigidly supported on both sides of wall assembly. The following types of through-penetrating products may be used:
A. Max four copper conductors No. 4/0 AWG (or smaller) aluminum or steel Armored Cable+ or Metal-Clad Cable+. When armored or metal-clad cable is used, the T Rating is 1/2 hr.
AFC CABLE SYSTEMS INC
B. Two or more twisted copper conductors No. 6 AWG (or smaller) Power Limited Circuit Cable+ with or without a jacket under a metal armor. When Power Limited Circuit Cable+ is used, the T Rating is 1/2 hr.
AFC CABLE SYSTEMS INC
C. Two or more twisted copper conductors No. 10 AWG (or smaller) Power Limited Fire Alarm Cable+ with or without a jacket under a metal armor. When Power Limited Fire Alarm Cable+ is used, the T Rating is equal to the F Rating of the firestop system.
AFC CABLE SYSTEMS INC
D. Two or more twisted copper conductors No. 12 AWG (or smaller) Non Power Limited Fire Alarm Cable+ with or without a jacket under a metal armor. When Non Power Limited Fire Alarm Cable+ is the T Rating is equal to the F Rating of the firestop system.
AFC CABLE SYSTEMS INC
3. Fill Void or Cavity Material* ? Sealant or Putty ? Min 5/8 in. thickness of fill material installed within annulus, flush with both surfaces of wall assembly. Additional fill material installed such that a min 1/4 in. diam crown is formed around the through-penetrant on both sides of the wall.
SPECIFIED TECHNOLOGIES INC ? SpecSeal Series 100 Sealant or SpecSeal Putty
