Abstract: This invention is a new and unique acoustical board formed of fire retardant materials which board has the unique qualities of being fire retardant, sound absorbing, heat insulating, and decorative, and may be formed virtually in any desired size and shape. It is composed of fiberglass reinforced melamine resin panels or the like having one grooved surface covered by fiberglass cloth with perforations suitable to admit sound waves into the grooved areas of the underlying board in such manner as to trap, and debilitate such sound waves therein, and, it has been particularly formed so as to be oil impervious, while retaining the sound deadening qualities by the insertion of a thin membrane of oil impervious material between the fiberglass cloth and the melamine panel.
