Installation shall be in strict accordance with
manufacturer’s written instructions. The product shall
be classified by Underwriter’s Laboratory, Inc. as a
Fill, Void and Cavity Material. When installed in
accordance with systems outlined in the current UL
Fire Resistance Directory and tested in accordance

6. Installation Techniques
1. Install 3M Fire Barrier Pillows so the 9 in. (22,8 cm)
dimension travels through the wall, or floor.
2. One of the large faces of the 3M Fire Barrier Pillow
shall face the framing of the penetration.
3. A mixture of following pillows may be necessary to
obtain the correct compression (20% - 25%
compression).
FB 249: 2 in. x 4 in. x 9 in.
(50,8 mm x 101,6 mm x 228,6 mm)
FB 269: 2 in. x 6 in. x 9 in.
(50,8 mm x 152,4 mm x 228,6 mm)
FB 369: 3 in. x 6 in. x 9 in.
(76,2 mm x 152,4 mm x 228,6 mm)
4. Begin by installing as many FB 369 pillows, as
possible. Then install additional FB 269 and
FB 249, as needed, to complete the installation.
Storage
The 3M Fire Barrier Pillows must be stored in a dry
warehouse environment. Pallets should not be
stacked.
Methods:
1. Choose the appropriate firestop system in the 3M
Fire Protection Products Applications and
Specifiers Guide, or the UL Fire Resistance
Directory.
2. Starting in the bottom corners of the penetration,
install 3M Fire Barrier Pillows vertically so that the
large faces of the pillows are facing the framing.
See picture.
3. Fill in the space between vertical pillows with
pillows installed horizontally in rows.
4. Repeat steps 2 and 3 until the penetration is
completely full. See Figure 2.
5. If required, apply a minimum 1 in. (25,4 mm) depth
of 3M Moldable Putty+ in all four corners between
the vertical pillow and framing.
6. Check for any openings between pillows (and
penetrating items) greater than 1/16 in. (1,5 mm)
Fill any openings between 1/16 in. (1,5 mm) and
1-1/2 in. (38 mm) with a minimum 1 in. ( 25,4 mm)
depth of 3M Moldable Putty+.
Calculating Pillow Requirement:
Measure the opening, in inches, and multiply the
length by the width to get the total area. Estimate the
area occupied by the penetrating items and subtract it
from the area of the opening. This is the amount of
area to be firestopped.
For example, an opening through a gypsum wall
measures 30 in. x 18 in. (76 cm x 45 cm).
The openings area 30 in. x 18 in. (76 cm x 45 cm) is
540 sq. in. (3483 sq. cm). A 24 in. x 4 in. (60,9 cm x
10 cm) cable tray which is 40% full of cables is
running through the opening. The tray occupies an
area 0.4 in. x 24 in. x 4 in. (10,1 mm x 60,9 cm x
10 cm) of 38.4 sq. in. (247,7 sq, cm). The amount of

area to be firestopped 540 sq. in. – 38.4 sq. in.
(3483 sq. cm - 247 sq. cm) is 501.6 sq. in.
After calculating the amount of area to be firestopped
determine the number of each size pillow needed to
firestop the penetration. In most penetrations you will
need to use some of each of three sizes of pillows.
Determine the number of each pillow by dividing the
total area by the pillows Estimating Number and
round up the nearest whole pillow. See Table1.
In this example it should take approximately
twenty-five FB 369 pillows, eleven FB 269 pillows,
and three FB 249 pillows to properly firestop this
penetration.
7. Maintenance
Inspection: Installations should be inspected periodi-
cally for subsequent damage. Damaged pillows shall
be replaced.
Retrofit: Cables may be added or replaced by simply
removing and replacing pillows and putty as required.
