Fire Rated Doors – Certified Fire Doors for Commercial & Residential
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.
- Best for: Architects, PMC consultants, builders, hotels, hospitals, factories, and housing societies
- Use when: NBC 2016 fire NOC or compliance with stairwell compartmentation or insurance regulations is needed
- Rating range: From FD 30 to FD 180 minutes, with options for steel and timber
We also make wooden fire doors and wooden acoustic doors for hotels, hospitals and offices that need fire safety and sound control in a single door.
Our team surveys the opening, recommends the right rating and core, and installs each door set with its certified hardware so it passes inspection the first time.

What Is a Fire Rated Door?
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.
Who Needs a Fire Rated Door and When
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.
Types of Fire Rated Doors We Manufacture
- Fire Rated Steel Doors – Fire rated steel doors combine pressed galvanized steel skins with a rock wool or ceramic wool core, especially for use in the walls of plant, electrical, and warehouse rooms to provide both impact and fire resistance.
- Fire Rated Sliding Doors – Sliding doors are used in tight corridors where swing clearance is not possible, as well as in applications where openings have been previously constructed and are not easily retrofitted. Fire rated sliding doors utilize a fusible link or self-closing mechanism triggered by a heat or smoke detection device.
- Industrial Fire Rated Doors – Fire rated doors for industrial applications in high fire-load environments such as factories, warehouses, and data centers are built to withstand a high fire rating from FD 90 to FD 120 and have reinforced frames to resist high impact as well as high-traffic and forklift openings.
- Wooden and Acoustic Fire Rated Doors – Finish and sound control are as important as fire safety for hotels, hospitals, and offices. For these particular markets Ecotone has developed a certified timber fire rated door system, which provides fire protection as per IS 3614, and acoustic attenuation up to STC 55 in a single assembly.

How Do You Choose Reliable Fire Rated Doors Manufacturers?
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.
Checklist before ordering:
- Ask for the test certificate and confirm the lab and date
- Confirm the tested assembly matches leaf, frame, seals, and hardware
- Ask for project references in your specific sector
- Confirm availability of replacement seals after 5 to 10 years
According to the Bureau of Indian Standards, <cite index=”2-1″>BIS mark compliance on fire doors signifies adherence to IS 3614 standards, confirming the product’s readiness for emergency use.</cite> Buyers should always cross-check this certification before procurement.
Wooden Fire Doors and Wooden Acoustic Doors
Wooden fire doors use a solid timber frame, a fire resistant core, intumescent seals and fire rated hardware, tested together as one assembly under IS 3614. They are the usual choice for hotel rooms, hospital corridors, apartment entrances and offices, where a steel door would look out of place.
Wooden acoustic doors take the same build a step further with a denser core and perimeter sound seals, so the door holds back noise as well as fire. Many projects need both in one leaf, for example a hotel room next to a busy corridor or a doctor’s consultation room. Tell us the fire rating and the sound level you need, and we will match the core and seals. For doors that only need sound control, read our acoustic wooden doors guide.

Frequently Asked Questions for Fire Rated Doors
Yes, NBC 2016 mandates FD 60-90 doors on stairwells above 15-30 metres.
No, incorrect installation voids the certification; use a trained installer.
Yes, self-closing is mandatory; propping the door open removes all protection.
FD 30 resists fire 30 minutes; FD 60 resists it twice as long.
Yes, if IS 3614 certified; timber doors match steel on tested performance.
Test certificates are typically valid three years; recheck before major renovations.
Yes, they suit tight industrial corridors needing automatic fire-triggered closing.
Yes, annual inspection of seals, gaps, and hardware is code-required.
Only acoustic fire rated doors offer both; standard fire doors give minimal sound control.
