Spray-on fireproofing is a method used to enhance the fire resistance of buildings and structures. This technique involves applying a special fire-resistant material, often made from fiberglass or mineral wool, directly onto surfaces like steel beams and concrete. The spray creates a protective layer that helps prevent flames from spreading and reduces heat transfer. This fireproofing method is commonly used in commercial and industrial settings, where safety regulations require structures to withstand high temperatures. It is valued for its ease of application and effectiveness, making it a popular choice for construction projects aiming to improve fire safety.
