Abstract
The coating of shredded paper insulation with a powdered or particulate fire retardant agent mixed with an anti-static agent to enhance coating is further improved by applying a precoat of a mixture of fire retardant agent and anti-static agent, the precoat mixture containing only a relatively minor portion of the final fire retardant coating, and subsequently coating the paper particles with the remaining fire retardant agent.
