Common questions from architects, PMCs, fire consultants and purchase managers specifying fire-rated, acoustic and lead-lined doors. If your question is not answered here, our technical team responds within 24 hours.
What fire ratings do Tufwud fire doors carry?
Tufwud manufactures two ISI-marked insulated fire door lines: FD60ID, rated for 60 minutes, and FD120ID, rated for 120 minutes. Both are supplied with test and certification documentation for your project file.
What does a "fully insulated" fire door mean, and why does it matter?
A fire door can be rated for integrity alone (it holds back flame and smoke) or for integrity and insulation (it also limits the temperature rise on the side away from the fire). An insulated door keeps the escape route survivable for people passing it during evacuation. Tufwud was the first Indian manufacturer to carry an ISI mark for a fully insulated fire door.
Which Indian standard applies to fire doors, and do I need an ISI mark?
IS 3614 is the Indian Standard covering fire check doors. An ISI mark is third-party certification by the Bureau of Indian Standards that a product conforms to the relevant standard. Many PMCs, fire officers and government tenders ask for ISI-marked doors specifically - confirm the exact requirement with your fire consultant or the authority having jurisdiction for your building.
What acoustic performance can Tufwud doors achieve?
Tufwud acoustic and soundproof fire doors are engineered for sound insulation of up to 42 dB. Performance depends on the door leaf construction, frame, seals and the installation detail, so share your target dB rating with our technical team before finalising specs.
Do you supply lead-lined doors for X-ray and radiology rooms?
Yes. Tufwud lead-lined doors provide radiation shielding for X-ray rooms, CT and radiology suites, and can be combined with fire rating where the room also sits on a protected escape route.
What other door types does Tufwud manufacture?
Beyond the fire-rated range: glazed fire doors where visibility through the opening is required, Gatemet metal fire doors, acoustic and soundproof doors, lead-lined doors, and laminated, veneered and designer doors for interior applications.
Where does Tufwud supply, and where is the factory?

The company has served over 2,000 clients across more than 2,800 projects, with active supply across West Bengal, Maharashtra, Delhi, Karnataka, Gujarat and Sikkim.
