Firemen wear hats made of fiberglass because fiberglass is lightweight, durable, and provides excellent insulation against heat. Unlike metal, which can become extremely hot and potentially cause burns, fiberglass retains its shape and protective qualities under high temperatures. Additionally, fiberglass helmets can be designed to include ventilation and impact resistance, enhancing safety and comfort for firefighters in challenging environments.
