Environmental Cycling of Cellulosic Thermal Insulation and Its Influence on Fire Performance.

Abstract

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.
