1. What is the purpose of a fire door?
The purpose of a fire door is to contain fire and smoke, preventing them from spreading between compartments of a building. It is essential for maintaining structural integrity during a fire, ensuring a safe evacuation, and safeguarding people and property. Certified fire doors are crucial components of any passive fire protection system.Tufwud Fire Doors go a step further—being fully insulated and ISI-marked, they offer certified protection with 120-minute fire resistance.
2.What is the difference between a fire door and a normal door?
A fire door is specifically designed to resist fire, smoke, and heat for a defined period—usually 30 to 120 minutes—allowing safe evacuation and containing the fire within a compartment. It makes use of ISI-certified parts, fire-rated core materials, and specialized hardware such as auto-closers and intumescent seals. In contrast, a normal door lacks these safety features and fails quickly during a fire. Fully insulated and ISI-marked, Tufwud Fire Doors guarantee guaranteed protection and unparalleled dependability in emergency scenarios.
4. What is the standard size of a fire door?
Depending on the type of building, a fire door’s conventional dimensions normally fall between 750 and 1200 mm in width and 2000 and 2400 mm in height. However, fire doors must also comply with clear opening width and height requirements for accessibility and evacuation. Sizes may vary for single or double-leaf configurations.
Tufwud Fire Doors are available in custom and standard sizes, tailored to meet project-specific safety and compliance needs.
5. How can I install my fire door
To guarantee performance and compliance, fire doors must be fitted by qualified personnel. Installation involves fixing the frame securely, using fire-rated anchors, followed by mounting the shutter with certified hinges, closers, and seals. In addition to properly positioning intumescent strips, gaps surrounding the door must fall within the specified bounds. Final inspection ensures full functionality.
Tufwud provides trained technicians and detailed installation manuals to guarantee certified fire door performance.
6. How much does a fire-rated door cost?
The price of a fire door varies based on its fire rating (FD30 to FD120), size, core material, finish, and required hardware. Factors like acoustic insulation or glass inserts can add to the cost. Competitively priced and completely customisable, Tufwud Fire Doors provide ISI-marked safety without sacrificing style or cost.

How do you prove a fire door?
What is a 2-hour fire-rated door? A 2-hour fire-rated door (FD120) is designed to withstand fire, smoke, and heat for up to 120 minutes, preventing spread between compartments and enabling safe evacuation. These doors are crucial for important fire zones because they are constructed with insulated cores, fire-rated hardware, and intumescent seals. They are commonly installed in hotels, hospitals, malls, high-rise buildings, institutions, and offices, where extended protection is crucial.
Tufwud’s ISI-marked FD120 doors are tested as per IS:3614, ensuring certified safety and compliance.
What is a 1-hour fire-rated door?
A 1-hour fire-rated door (FD60) is designed to resist fire, smoke, and heat for up to 60 minutes, helping to contain fire within a compartment and allow safe evacuation. These doors are constructed with fire-resistant cores, certified hardware, and intumescent seals that expand during a fire to block gaps.
They are widely used in residential buildings, hotel guest rooms, auditoriums, server rooms, bungalows, and mid-rise commercial spaces.
Tufwud’s ISI-marked FD60 doors ensure reliable, certified protection for medium-risk zones.
How to make a door acoustic?
To make a door acoustic, it must be designed to block or absorb sound transmission. This involves using a high-density core like solid wood, particleboard, or mineral wool, along with acoustic seals around the frame and drop-down door bottoms to prevent sound leakage. The door should be tightly fitted, and the frame must be sealed with gaskets or soundproofing strips. Laminates or composite layers can further enhance sound insulation.
Tufwud Acoustic Doors are lab-tested for STC ratings, offering both fire and sound protection—ideal for hotels, studios, theatres, auditoriums, offices, and premium residences.
What is lead lined used for?
Lead lined is used to provide radiation shielding in areas exposed to X-rays, gamma rays, or other harmful radiations. It is commonly applied in healthcare facilities, especially in X-ray rooms, CT scan suites, and radiation therapy units, to protect patients, staff, and the public from radiation exposure. Lead sheets or lead-lined boards are integrated into walls, doors, partitions, and ceilings to block or reduce radiation transmission, as mandated by regulatory standards like AERB.
Tufwud’s lead-lined doors combine certified radiation shielding with fire-rated and acoustic performance for complete safety in sensitive environments.
Can glazed doors be fire doors?
Yes, glazed doors can be fire doors—as long as the glass used is fire-rated and tested for the required duration (e.g., 30, 60, or 120 minutes). These doors combine fire-resistant core materials with special fire-rated glass, which can resist heat, flames, and smoke for a certified period. The glass is usually clear and toughened, often with intumescent interlayers that expand to block heat transfer during a fire.
Tufwud offers glazed fire doors that are ISI-marked, aesthetically pleasing, and fully compliant with fire safety regulations—ideal for hospitals, offices, and modern interiors.
What are the specifications of a fire door? Fire doors are built to meet specific safety standards. Key specifications include:
Fire rating: 60 minutes & 120 minutes
Fire Door Core material: steel, mineral wool, vermiculite, ceramic fiber, and honeycomb cores.
Tufwud Fire Doors are fully ISI-marked and customizable, combining certified safety with aesthetic and functional flexibility.
