Firestopping products are essential passive fire protection materials used to reinstate the fire resistance of walls, floors and joints after they are penetrated or separated for building services. Pipes, cables, cable trays, ducts and construction joints can create openings through which fire, smoke and toxic gases may spread. A correctly selected and installed firestop system helps compartmentalize a building, giving occupants more time to evacuate and supporting the building’s overall fire-safety strategy.
At NEVIQ INFRATECH, we understand that effective firestopping is not simply about filling an opening. It is about selecting a suitable, tested system for the actual site condition.
Categories of Firestopping Products and Their Intended Applications
Firestop Sealants
Firestop sealants are used for small to medium openings, perimeter gaps and construction joints. Depending on the tested system, they can be applied around cables, metal pipes, service penetrations and linear joints.
Typical applications include:
- Gaps around cables and conduits
- Metal pipe penetrations
- Construction and control joints
- Head-of-wall and slab-edge joints
- Smoke-sealing requirements where included in the tested system
Intumescent Pipe Collars and Wrap Strips
Pipe collars and wrap strips are designed primarily for combustible plastic pipes. In a fire, the intumescent material expands to help close the opening left when the pipe softens or melts.
Typical applications include:
- uPVC, PVC, HDPE and similar combustible pipe penetrations
- Plastic pipes through fire-rated walls and floors
- Retrofit and new-construction pipe penetrations
- Pipes with specific annular-gap, insulation or orientation requirements
Firestop Mortar and Firestop Compounds
Firestop mortars and compounds are commonly used to seal larger openings, shaft penetrations and floor openings. They can form a robust firestop seal around permitted services when used as part of an approved system.
Typical applications include:
- Large slab openings
- Multi-service penetrations
- Service risers and shafts
- Floor penetrations requiring a rigid closure
Firestop Boards and Coated Panels
Firestop boards are used for larger or irregular openings, particularly where multiple cables, pipes or trays pass through a single opening. They can be cut and configured to suit the opening and service arrangement, in accordance with the tested system.
Typical applications include:
- Large MEP penetrations
- Cable-tray and mixed-service openings
- Complex openings in walls and floors
- Openings requiring future service additions, where the system permits
Firestop Putty Pads, Putty Sticks and Moldable Materials
These products are useful for electrical boxes, small cable openings and irregular gaps. Their flexibility makes them particularly valuable where service configurations are difficult to seal with rigid products.
Typical applications include:
- Back-to-back or individual electrical boxes
- Small cable and conduit penetrations
- Irregular gaps around services
- Localized sealing and service modifications
Firestop Blocks, Plugs and Pillows
Firestop blocks, plugs and pillows are selected where future re-entry is expected. They allow cables to be added or removed while maintaining a firestop solution when installed correctly.
Typical applications include:
- Data centers and telecom rooms
- Cable-tray openings
- Electrical rooms
- Frequently modified cable penetrations
Linear-Joint Firestop Systems
Linear-joint systems are designed for joints that may move due to thermal change, structural movement or deflection. The required movement capability and fire rating must be verified for every condition.
Typical applications include:
- Head-of-wall joints
- Curtain-wall perimeter and slab-edge joints
- Expansion joints
- Wall-to-floor and wall-to-wall movement joints
Cast-In Devices, Sleeves and Firestop Pathways
Cast-in devices and sleeves are installed before concrete is poured or during planned construction works. Firestop pathways can assist in organizing future cable routing through protected compartments.
Typical applications include:
- Planned slab penetrations
- New-build MEP coordination
- Repetitive service penetrations
- Controlled cable-routing locations
Does “One Product Fits All” Apply to Firestopping?
No. A “one-fits-all” approach does not apply to firestopping.
A sealant that is appropriate for a cable penetration may not be suitable for a plastic pipe, a large mixed-service opening or a movement joint. The performance of a firestop solution depends on the complete tested assembly—not only on the product selected. The wall or floor type, opening size, service arrangement, annular gap, pipe insulation, fire rating and installation details all affect the correct solution.
Using a generic product without matching it to a tested and approved system can compromise fire compartmentation. The right approach is to evaluate the actual condition and specify a compatible firestop system.
Information Required to Recommend the Correct Firestopping Product
Before selecting a firestop product, NEVIQ INFRATECH reviews the following details:
- Required fire-resistance rating and applicable project requirements
- Type of barrier: wall, floor, shaft wall, drywall, concrete or masonry
- Barrier thickness and construction details
- Size, shape and location of the opening
- Type of penetration: cable, conduit, metal pipe, plastic pipe, tray or mixed services
- Pipe material, outside diameter, wall thickness and insulation details
- Cable quantity, cable-tray dimensions and planned future additions
- Annular-gap dimensions around each service
- Whether the penetration is new, existing or likely to be modified later
- Whether movement, vibration, water, smoke, acoustic or environmental exposure must be addressed
- Access available for installation and inspection
- Relevant tested-system documentation, drawings and approval requirements
This assessment helps ensure that the specified system is technically appropriate, constructible and aligned with the project’s fire-safety objectives.
