THE STORY of fire retardant lumber is as old as man. Since the day that he learned to make a fire, man has endeavored to learn how to control it. Wood is one of man's oldest building materials. History has recorded the uses that he has made of wood, as well as the conflagrations that have caused him to investigate the possibilities of reducing the combustibility of wood.
