1. Wall assembly – The 1 and 2 hr fire rated gypsum board/stud wall assemblies shall be constructed of the materials and in the manner
specified in the individual U300, U400 or V400 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. (51 by 102 mm)
lumber spaced 16 in. (406 mm) OC. Steel studs to be min 3-1/2 in. (89 mm) wide and spaced max 24 in. (610 mm) OC.
B. Gypsum board* – Thickness, type, number of layers and fasteners as required in the individual Wall and Partition Design. Diameter of
opening shall be 1-1/2 in. (38 mm) larger than the outside diam of tubing (Items 2).
The hourly F Rating of the firestop system is equal to the hourly fire rating of the wall assembly in which it is installed. The hourly T
Rating is 0 and 1-3/4 hr for 1 and 2 hr rated assemblies, respectively.
2. Crosslink polyethylene (PEX) tubing – Nom 2 in. (51 mm) diam (or smaller) SDR 9 PEX tubing for use in closed (process or supply)
piping system. Tubing installed concentrically or eccentrically within opening. Annular space between tubing and edge of opening to be min
0 in. to max 1-1/2 in. (38 mm). Tubing to be rigidly supported on both sides of wall assembly.
3. Fill, void or cavity materials* – caulk or sealant – Min 5/8 in. (16 mm) thickness of fill material applied within the annulus, flush with
both surfaces of wall assembly. An additional min 1/2 in. (13 mm) bead of fill material applied at the tubing/gypsum board interface at point
contact location on both surfaces of wall assembly.

Step four
Ensure the selected re
assembly document matches:
• Type of construction
• F rating of assembly
• Through penetrant dened
as crosslinked polyethylene
pipe or PEX pipe
• Range of pipe size being
installed
• Penetration hole size and
shape
• Firestop solution availability
(See Figures 3-14, 3-15 and
3-16.)
Note: It may be desirable to
select a restop product that
can be used for other MEP
system penetrations, such as
drain, waste and vent (DWV)
and conduit applications. This
can help ease coordination on
the jobsite during the restop
installation.
Refer to the respective
restop manufacturer for
more information pertaining
to the appropriate application
of their products. Be mindful
of information stated in the
published listings to ensure
compliance during installation.
Note: Ensure the required
restop material dened in the
assembly (i.e., sealant) does
not come into contact with
Uponor EP ttings. Assemblies
dene the penetrating item
as “PEX pipe” and therefore
only PEX pipe shall come
into contact with the required
restopping material.
