User Guide

The 3M Fire Barrier Pillow is a self-contained,
highly intumescent product designed to firestop a
wide variety of through-penetrations including cable
trays (up to two per opening), conduit and blank
openings, which penetrate fire-rated construction.
During a fire, 3M Fire Barrier Pillow intumesces
(expands) and locks itself into place, completely
surrounding the penetrant(s) stopping smoke, fire
and toxic gases from spreading to the next room or
next floor for the rated time period. They are easy to
install and great for retrofit projects. Just remove and
replace pillows as needed.
3M Fire Barrier Pillows have been tested to the
ASTM E 814 test criteria and have been designed to
meet the intent of NEC, NFPA, SBCCI, BOCA and
ICBO building codes.
