NEVIQ INFRATECH provides passive fire-protection and firestopping solutions for buildings, industrial facilities and infrastructure projects across India. Passive fire protection is built into the structure to slow the spread of fire, smoke and heat, protect load-bearing elements, and maintain fire compartmentation.
Unlike active fire systems such as sprinklers and extinguishers, passive fireproofing works without manual intervention. It includes structural steel fire protection, fire-rated boards, mineral-wool barriers, façade perimeter systems, and firestopping of service penetrations and joints.
The National Building Code of India, NBC 2016, addresses fire and life safety under Part 4, including compartmentation and fire-protection provisions. BIS—National Building Code of India
Passive fireproofing products used in India
Intumescent coatings for structural steel
Intumescent coatings expand under fire exposure to form an insulating char layer around steel. They are commonly used in commercial buildings, airports, malls, hotels, offices and exposed-steel architectural designs.
Key manufacturers and product ranges include:
- Jotun — SteelMaster 600WF, 900WF, 1200WF, 90SB and 1200HPE
- Carboline — Thermo-Lag and Pyroclad systems
- Promat — intumescent passive fire-protection materials
Jotun’s India-facing SteelMaster range includes water-based, solvent-based and epoxy intumescent coatings for structural steel.
Cementitious and spray-applied fireproofing
Cementitious fireproofing is a spray-applied material used for steel and concrete protection, particularly in industrial, oil and gas, petrochemical, warehouse and large-scale projects.
Key manufacturers and product ranges include:
- Promat — FENDOLITE® MII cementitious fireproofing spray
- Carboline — Pyrocrete® cementitious fireproofing
- Carboline — Thermo-Lag® 2000-P and 2000-SP
Promat's FENDOLITE® MII is used for steel and concrete structures in oil, gas and petrochemical environments.
Fire-rated boards, encasement and mineral-wool systems
Fire-rated boards and stone-wool systems create protective enclosures around steelwork, ducts, cable trays, shafts, partitions and façade interfaces.
Key manufacturers include:
- Promat — calcium silicate boards and panel systems
- ROCKWOOL — stone-wool fire barriers, curtain-wall and penetration systems
Promat boards provide fire, heat, smoke and gas barriers, while ROCKWOOL India offers passive fire-protection systems for perimeter containment and through penetrations.
Frequently specified firestopping products in India
Firestop sealants
Acrylic, silicone and intumescent sealants are widely used for construction joints, linear gaps, cable and pipe penetrations, mixed-service openings and blank openings.
Promat :PROMASEAL®-A Spray --> Flexible acrylic spray sealant for joint applications and movement accommodation
Promat : PROMASEAL®-AG --> Intumescent acrylic mastic for cables, cable bundles, conduits, combustible pipes and insulated pipes
Promat : PROMASEAL®-S --> Flexible silicone sealant for joints, including external applications
Promat : PyroPro® LST --> Acrylic ablative sealant for linear gaps, single- and multi-service penetrations, and blank openings
Hilti : CP 606 --> Flexible acrylic firestop sealant for joints and through penetrations
Hilti : CP 601S --> Silicone firestop sealant for movement joints and pipe penetrations
Hilti : FS-ONE MAX --> Intumescent sealant for a range of penetrations
PROMASEAL®-AGis used as an intumescent, single-component acrylic mastic for cables, conduits and combustible-pipe applications. PyroPro® LST is usedfor linear joints, penetrations and blank openings, with fire resistance dependent on the tested system.
Firestop collars and wrap strips
Intumescent collars and wrap strips are essential for combustible plastic-pipe penetrations. In a fire, they expand to help close the opening left when the pipe softens or melts.
Key manufacturers and products include:
- Hilti — CP 644 Firestop Collar and CP 648-E Endless Wrap Strip
- ROCKWOOL — Conlit® Pipe Collar
- Promat — intumescent firestopping materials and engineered seals
Firestop mortar and foam
Firestop mortars and foams are commonly selected for large, irregular and mixed-service openings containing cables, cable trays, metal pipes and plastic pipes.
Key manufacturers and products include:
- Hilti — CP 636 Firestop Mortar and CP 620 Firestop Foam
- ROCKWOOL — Conlit® LITE Firestop Compound
- Promat — PROMASTOP®-I liquid coating for penetration seals and coated batt systems
Re-enterable cable blocks, sleeves and transit systems
Data centers, telecom facilities, electrical rooms and risers often require re-enterable firestop solutions so that future cabling can be added without compromising compartmentation.
Key manufacturers and products include:
- Hilti — CFS-BL Firestop Blocks and CP 653 Firestop Speed Sleeves
- ROCKWOOL — firestop pillows, sleeves and cable firestops
- Promat — sealants and coatings for cable-penetration systems
Selecting the right firestop system
NEVIQ INFRATECH recommends selecting fireproofing and firestopping systems on the basis of:
- Required fire-resistance rating
- Fire-rated wall, floor, steel or façade assembly
- Service type: cable, cable tray, metal pipe, plastic pipe, duct or mixed services
- Opening size, annular gap and joint-movement requirement
- Indoor, outdoor, wet, corrosive or high-temperature environment
- Tested system documentation, installation requirements and inspection records
A firestop installation is not simply the application of a sealant or mortar. It must be a tested and documented system that matches the actual site condition. This is the right approach to help preserve compartmentation, limit fire and smoke spread, and support safer building performance.
