Abstract
Fire resistant safety glasses are provided that included wire glasses having another layer of fire resistant material. In certain embodiments, a piece of wire glass has a sheet of fire resistant film adhered thereto. Such glasses have improved impact resistance compared to conventional wire glasses. Fire resistant safety glasses are also provided that combine improved impact resistance and fire protection and in some embodiments, improved thermal insulation, improved reflectivity and shielding against ionizing radiation. Safety glasses of this invention can be made using non-tempered or tempered glass, fire resistant plastics, fire resistant fiberglass, ceramics and other fire resistant glazing materials, and can be made in multiple layers, having one or more pieces of wire glass or fire resistant glazing materials. Fire resistant safety glasses of this invention can be made inexpensively and can have improved properties compared to conventional wire glass. By providing increased mechanical strength, the glasses of this invention can remain intact even if broken, thereby decreasing the risk of personal or property damage caused by glass shards.
