FlameSafe® Pillows are a durable firestop
product allowing easy access to cables and
cable trays for through-penetration in firerated floors and walls.
Easy to install, firestop pillows allow for
multiple re-entry. They function through a
unique phase reaction to intumesce and seal
out fire and smoke. They are an ideal alternative to firestop large openings and are
approved for multiple cable tray applications.
Applications
FlameSafe Pillows are used as a firestop to
maintain fire ratings up to 3 hours wherever
penetration occurs through fire-rated walls
and floor assemblies. They may be used
during the construction phase as a temporary
firestop or left in place as a permanent
firestop. These pillows have been tested in

1. Figure square inches (mm) of opening to be firestopped (W x H).
(Approximations based on blank opening, subtract area occupied by penetrants from total area of opening.)
2. Using the chart above for each pillow size, multiply total square inches (mm) of opening by the percentage of opening
each pillow size will fill. Next divide this sum by the square inch (mm) coverage given or each pillow size.
Round all answers up to the nearest whole number. This number is the total number of each pillow size to order.
3. Example:
12 in. x 12 in. opening = 144 in.2 (305 mm x 305 mm opening = 93025 mm2)
FSPIL4
144 in.2 x .70 = 101 in.2 (93025 mm2 x .70 = 65118 mm2)
101 in.2 ÷ 27 in.2 = 3.7 = 4 FSPIL4 (65118 mm2 ÷ 17420 mm2 = 3.7 = 4 FSPIL4)
FSPIL2
144 in.2 x .15 = 22 in.2 (93025 mm2 x .15 = 13954 mm2)
22 in.2 ÷ 13.5 in.2 = 1.6 = 2 FSPIL2 (13954 mm2 ÷ 8710 mm2 = 1.6 = 2 FSPIL2)
FSPIL1
144 in.2 x .15 = 22 in.2 (93025 mm2 x .15 = 13954 mm2)
22 in.2 ÷ 6.75 in.2 = 3.2 = 4 FSPIL1 (13954 mm2 ÷ 4355 mm2 = 3.2 = 4 FSPIL1)
Therefore, four FSPIL4, two FSPIL2 and four FSPIL1 pillows are required.
