Abstract:

The burning characteristics of various thermal insulation materials were investigated with a view to determining their comparative suitability for submarine hull insulation. The types of materials represented included 1 urethane foam constructed with a laminated barrier material an insulation system previously developed by the U. S. Naval Applied Science Laboratory, 2 corkboard, 3 expanded vinyl plastic, and 4 fibrous glass board. The fibrous glass board, although not used as submarine hull insulation, was included in this program for comparison purposes. The fire tests conducted were 1 NAVAPLSCIENLAB Large Scale Fire Tests, 2 Columbia Fire Tests, 3 NAVAPLSCIENLAB Decking Fire Tests, 4 ASTM Flammability Tests, and 5 Underwriters Laboratories Fire Tests. On the basis of the data and information obtained, it was concluded that the urethane foam constructed with a laminated barrier, was characterized by less hazardous factors than the corkboard or the expanded vinyl foam. None of the 5 tests were found completely satisfactory for evaluating the burning characteristics of a thermal insulation material for submarine hulls. Author
