A Fire Door Drop Seal is an advanced safety and performance accessory designed to provide effective sealing at the base of fire-rated doors. It works automatically by lowering a concealed or surface-mounted seal to close the gap beneath the door once it is shut, and retracting when the door opens to allow smooth movement without friction. This intelligent mechanism ensures consistent protection without compromising the door’s usability. The primary purpose of a fire door drop seal is to prevent the passage of smoke, flames, and hot gases during a fire, thereby maintaining the door’s fire-resistance rating and contributing to the overall compartmentalization of a building. By sealing the critical threshold gap, it slows down the spread of fire and toxic fumes, allowing valuable time for safe evacuation and minimizing property damage. In addition to fire protection, these seals are also highly effective in blocking sound, dust, drafts, insects, and light penetration, making them a versatile solution for modern buildings. Constructed from durable aluminium housing and equipped with intumescent and elastomer sealing components, fire door drop seals offer long-lasting reliability under demanding conditions. They are available in both face-fixed and concealed models, allowing seamless integration with a wide variety of wooden, metal, and composite fire doors. Their sleek design ensures they blend discreetly with the door structure while maintaining full compliance with international fire and acoustic standards. Widely used in commercial complexes, residential apartments, healthcare facilities, educational institutions, cleanrooms, and hospitality spaces, fire door drop seals enhance both safety and comfort. By combining fire resistance, acoustic insulation, and environmental sealing in a single solution, they are an indispensable component
