In addition to their core fire-resistant properties, fire doors are equipped with multiple functional components that enhance safety and usability. Intumescent seals are installed around the door edges and expand when exposed to heat, effectively sealing gaps to prevent smoke infiltration. Self-closing devices, heavy-duty hinges, and secure locking systems ensure the door remains closed during a fire event. Many models also feature fire-rated vision panels, acoustic insulation, and durable surface finishes, making them suitable for both commercial and residential applications while maintaining long-term durability and safety compliance.
