A study was conducted on climatological data for eleven
cities located throughout the United States. Findings
from this environmental study were used to develop
conditioning cycles for a research project on the
influence of environments on the fire performance of
loose-fill cellulosic thermal insulation. Six
cellulosic insulation materials containing 25 percent by
weight of fire retardant chemical add-on of different
compositions were specially manufactured for this study.
These materials were tested to establish a baseline.
After the materials were exposed to the various
environmental cycles, they were tested for fire
performance. Results from these tests show that
environmental exposure can have a significant effect on
the fire performance of cellulosic insulation materials
and indicates that long term fire protection provided by
fire retardant compounds may be limited.
