Quick Answer: Fire Rated Doors are sets of doors with a leaf, frame, seals, and hardware that are tested to stand up to fire, heat, and smoke for a certain amount of time (30, 60, 90, or 120 minutes) as defined in IS 3614. Fire rated steel doors, sliding doors, and industrial fire rated doors for use in commercial, residential, and institutional construction in India from Ecotone (Packsound) are made to this standard, and each comes with a valid fire rated door label and a complete hardware set that is tested as one assembly.

A fire-rated door is a door constructed and lab-tested to seal in fire, bar smoke, and slow the spread of heat for a particular amount of time. Unlike a normal door with a fire-resistant design, a genuine fire rated door has a test certificate given after that specific door leaf, frame, seal, and hardware are tested in a furnace. This is important at the time of specification, since a door that “looks” fire rated but has no matching test report provides no actual protection during a real fire scenario.
Fire rated doors are used in compartmentalized areas as required by building codes, insurance underwriters, and/or fire NOC authorities in stairwells, lift lobbies, server rooms, kitchens, and industrial fire zones. Architects design them; PMC consultants check them at the ordering step; and facility managers keep them in service throughout a building’s life. At Ecotone, we provide fire rated steel doors and fire rated wood doors for high-risk occupancies as per the NBC 2016 rating, such as hotels, hospitals, IT parks, warehouses, pharmaceutical plants, and high-rise residential buildings.

| Myth | Reality |
|---|---|
| Any heavy steel door is fireproof | Only a tested, certified assembly is fire rated |
| Fire doors can stay open with a wedge | A wedged fire door provides zero protection |
| Hardware brand does not matter | Substituted hardware voids the fire certification |
| One test covers all door sizes | Each size and configuration needs its own test scope |
Make sure the manufacturer has a latest IS 3614 Part 2 test report from a NABL-accredited lab or CBRI, that the report matches the exact assembly you are purchasing, and that they provide installation and after-sales support, not just supply only.
