Overview
Delhi has adopted the National Building Code of Safety (NBCS) 2026 as law: exit and compartment fire doors need certified doorsets fitted with intumescent seals, and fire audits in Gurugram, Noida and Ghaziabad are following the same reference. Wedge Industries Limited supplies its INTUF-family intumescent strips, combined fire-and-smoke seals, intumescent putty and boards from Faridabad to fire-door OEMs, contractors and building owners — and fits the same seals to the fire-rated doors it assembles.
Passive fire protection is the fastest-growing Wedge line in NCR: hospitals, hotels, malls, data centres and high-rise residential towers are retrofitting exit doors to close audit findings, and door manufacturers in Faridabad, Ghaziabad and Bhiwadi need a local certified-seal supplier.

Installation and specification notes
Strips are pressed into a routed groove in the frame or leaf edge or surface-fixed with the self-adhesive backing on a clean, dry surface; mitre at corners and keep continuous. Pair the seal grade with the tested door design (WFD30/60/90/120 with FP1000, WedgeMAG or FP60/FP120 boards and HDRW 850 infill) — the seal is part of the tested assembly, not an accessory.

Frequently asked questions
What does NBCS 2026 require for fire doors in Delhi?
Exit and compartment doors must be certified doorsets with intumescent fire and smoke seals maintaining the door’s tested rating. Wedge supplies the seals, the door core boards and complete doorsets, and can survey existing doors for retrofit.
Which intumescent strip do I need for an FD60 door?
A 15 × 4 mm or 20 × 4 mm strip in the frame or leaf edge is usual for FD60, but the correct size and grade follow the tested door design; send the door specification and Wedge confirms.
Do the seals stop smoke as well as fire?
Combined fire-and-smoke seals add a brush or fin to the intumescent strip and are the normal choice for hospital and hotel corridors.
Are the seals certified?
The seals are tested to BS 476 and EN 1634 and referenced to IS 3614; test reports are supplied with the quotation and must be read with the door’s own test evidence.
Can you supply same day in Delhi NCR?
Standard sizes are stocked at Faridabad and usually reach Delhi, Gurugram, Noida and Ghaziabad within 24 hours.
