Fire-stopping products for Service Penetrations
Ensuring optimal fire safety within buildings is crucial, especially when fire-rated walls, floors, and other barriers are penetrated by services such as ducts, pipes and cables. Without effective fire stopping products in place, these openings can become pathways for fire and smoke to spread rapidly through a structure, putting both occupants and property at serious risk.
PFC Corofil offers a comprehensive range of fire stopping products for service penetrations, including intumescent pipe collars, pipe wraps, sealants, intumescent pillows, cable patches and the Coated Panel System. Whether you need fire stopping around pipes carrying water, gas, or drainage, or fire stopping around cables and cable bundles passing through fire-rated structures, our range provides a third-party certified solution for virtually every scenario. All of our penetration seal products are rigorously tested to European standards by independent third parties, guaranteeing their effectiveness in preventing the progression of fire and smoke through cable and pipe apertures in fire-resistant walls and floors. These intumescent fire stopping solutions work by expanding when exposed to elevated temperatures, sealing openings to halt the spread of fire between compartments and maintain the integrity of fire-rated construction.
Fire Stopping Around Pipes
When combustible plastic or insulated metallic pipework passes through fire-rated walls and floors, the pipe itself can melt in a fire, leaving an unprotected opening that allows flames and smoke to spread between compartments. Effective fire stopping around pipes is therefore essential to maintaining compartmentation integrity.
PFC Corofil offers several tested solutions for fire stopping around pipes, depending on the pipe material, diameter, and the construction type being penetrated:
The Intumescent Pipe Collar (CIPC) is designed for single plastic pipes and is available to suit pipe diameters from 32mm to 250mm. Tested to EN1366-3, it provides fire resistance periods of up to EI240. The collar is wrapped around the pipe at the point of penetration and, in the event of fire, the intumescent expands to close off the pipe opening. It is suitable for use with flexible walls, rigid walls, rigid floors and the PFC Corofil Coated Panel System, and is third-party certified.
The Intumescent Pipe Wrap (CIPW) also covers pipe diameters from 32mm to 250mm and provides fire resistance periods of up to 120 minutes when tested to EN1366-3. It features an integral self-adhesive strip to aid installation and requires no mechanical fixings.
The Universal Pipe Wrap (CUPW) provides a further option for fire stopping around pipes in walls and floors across a range of pipe types and construction configurations.
The Universal Pipe Wrap (CUPW) provides a further option for fire stopping around pipes where both plastic pipes and metallic pipes with insulation penetrate walls and floors. It is tested in conjunction with the PFC Corofil Coated Panel System and can be used in a variety of construction types.
The Insulated Fire Sleeves (CIFS) provide an alternative pipe closure solution for metal and plastic pipes penetrating non-load-bearing wall and floor constructions. Made from a flexible intumescent material consisting primarily of mineral fibres, intercalated graphite, and organic binders, they have been tested to EN1366-3:2009 and offer fire resistance periods of up to EI240. The sleeves also carry an acoustic rating of up to 49dB and are suitable for use with brick, block, masonry, and plasterboard constructions.
Fire Stopping Around Cables
Cables present a different challenge to pipes when it comes to service penetration fire stopping. Cable runs, bundles, and trunking passing through fire-rated walls and floors must be properly sealed to prevent the spread of fire and smoke, regardless of whether the cables themselves are combustible.
PFC Corofil offers a number of products specifically designed for fire stopping around cables:
The Cable Patch (CCPH) is made from intumescent putty and is used to reinstate the fire resistance of flexible or rigid walls penetrated by small cables, pipes, or conduits. Available as 60mm diameter discs for apertures up to 25mm x 25mm, and 100mm diameter discs for apertures up to 50mm x 50mm, cable patches are straightforward to install. Simply remove the backing and apply the patch around the service at the face of the wall. Third-party certified under UL-EU-01174-CPR.
The Intumescent Pillows (CIPI) are designed for fire stopping around cables in steel trunking and cable trays installed in block, masonry, or concrete walls, as well as directly around cables and single metallic pipes in masonry walls. Available in three sizes (Large 330 x 200 x 45mm, Medium 330 x 200 x 25mm, Small 330 x 50 x 20mm), they can be installed into openings up to 1100mm x 1100mm. Because they can be easily removed and reinstated, they are particularly well suited to applications where regular access to cables or services is required.
The Intumescent Putty Pad (CIPP) provides a further solution for fire stopping around cables in back boxes and similar applications.
Fire Stopping Products for Sealants and Compound Applications
Several products in the PFC Corofil range are specifically formulated for sealant and compound-based fire stopping of service penetrations, providing tested solutions where other closure devices may not be appropriate.
The Acoustic Intumescent Sealant (CAIS) is an acrylic-based sealant tested to both EN1366-3:2009 and EN1366-4:2006. It is used to reinstate the fire resistance of wall and floor constructions where they have been penetrated by cables or metallic pipes, and is also required to seal all joints and junctions when the Coated Panel System is installed. It is suitable for linear joints up to 60mm and is third-party certified.
The High Expansion Sealant (CHES) is an acrylic-based graphite sealant used for fire stopping of service penetrations containing single or multiple services. Supplied in 330ml cartridges, it provides fire resistance up to EI240 depending on application, and seals around combustible pipes up to 125mm including PVC, PE, PP, ABS, and PEX/MLC. It is also suitable for sealing around elastomeric foam and glass wool insulation on metallic pipes, and is Lubrizol FBC System Compatible, confirming chemical compatibility with FlowGuard Gold, BlazeMaster, and Corzan piping systems. It is third-party certified.
The Firestop Compound (CFSC) is a gypsum-based mortar containing perlite and fibres, mixed with water and either poured or trowelled into a prepared aperture around service penetrations. It is tested to BS476 part 20 and EN1366-3:2009, and provides up to 360 minutes of integrity and insulation fire resistance performance where there are no penetrations. It is suitable for floor openings up to 1200mm x 600mm, and around cable ladders, cable trays, and steel pipes up to 115mm. It is commonly specified for riser cupboards in high-rise buildings and is third-party certified.
Fire Stopping for Duct Penetrations
Where plastic vent ducts pass through fire-rated wall constructions, effective fire stopping is equally important. The Vent Duct Sleeve (CVDS) is a flexible intumescent closure device designed specifically for this application. Made from mineral fibres, intercalated graphite, and organic binders, and tested to EN1366-3:2009, it offers fire resistance periods of up to EI240 for PVC-U rectangular ducts. It also carries an acoustic rating of up to 49dB and is suitable for use with concrete, block, masonry, plasterboard, and PFC Corofil Coated Panel System constructions.
The Coated Panel System
The Coated Panel System (CCPS) is a coated mineral wool board used to reinstate the fire resistance of wall and floor constructions where apertures have been formed for the penetration of single or multiple services. Available in 1200mm x 600mm panels in 50mm (140kg/m³) and 60mm (160kg/m³) thicknesses, it accommodates apertures up to 730mm wide and 1200mm high depending on the application. It is suitable for use with plastic pipes, metallic pipes, cables, cable trays, and cable ladders, and is compatible with several other products in the PFC Corofil service penetrations range.
