Abstract
Fire retardant chemicals are designed to lower the temperature at which thermal degradation occurs. When these chemicals are used for roof sheathing, the combination of chemicals, elevated temperatures, and moisture can sometimes permaturely activate the fire retardant mechanism. The objectives of this study were to determine what kind of fire retardant chemicals are most susceptible to accelerating thermal degradation and at what temperature(s) this acceleration occurs.
