The fuels utilized for his or her experiments included a pure fuel burner, gasoline pool fire and polyurethane foam. The wall building was diversified between one sheet of gypsum wallboard with Wooden framing, a gypsum wallboard back and front with wood framing and gypsum wallboard front and back with fiberglass batt insulation from the voids from the wood framing.
