For fire doors to function effectively, they must be installed correctly and maintained in accordance with fire doors regulations. Essential components such as intumescent seals, which expand in heat to seal gaps, and self-closing mechanisms must be in working order. Fire-rated hinges, intumescent hinge pads, door frames, and glazing must also meet fire resistance standards to ensure the doorset can provide the intended level of protection. Regular inspections help ensure these features remain intact and free from obstruction, preventing potential failures in an emergency.
