Need Help Choosing a PFC Corofil System?
The correct PFC Corofil product depends on whether the cavity is ventilated or full-fill, together with the joint or cavity dimensions, orientation, supporting construction and fixing arrangement. Always match the installation to the applicable tested detail before ordering.

PASSIVE FIRE PROTECTION
PFC Corofil Cavity Barriers and Linear Gap Fire Stopping Systems
PFC Corofil is a UK manufacturer of passive fire protection products and forms part of the Tenmat Group. The Fire Protection Direct range focuses on products for cavity barriers, linear gap sealing and associated fire stopping applications, including open-state barriers, full-fill cavity barriers, linear gap seals and acoustic intumescent sealant.
Open-state cavity barriers are used where a ventilated façade cavity needs to retain an air gap during normal conditions, with the intumescent component designed to close that opening when exposed to fire. Full-fill cavity barriers perform a different function by filling the cavity where normal ventilation through that location is not required. These product types should not be treated as interchangeable.
Linear gap products are selected around factors such as joint position, width, orientation, supporting construction and movement requirement. Product-specific tested ranges and installation arrangements must be checked individually rather than applying one product's tested configuration to another.

APPLICATION GUIDANCE
PFC Corofil Cavity Barrier and Linear Gap Applications
PFC Corofil products are selected as part of tested systems. Open-state cavity barriers, full-fill barriers and linear gap seals perform different functions and must be matched to the relevant cavity, joint, supporting construction, orientation and fixing arrangement.
The table summarises common applications and product families that may be relevant. It is general guidance only and is not a project specification.
Always verify the current PFC Corofil tested detail, technical documentation and installation instructions before installation.
| Application | Typical requirement | Relevant PFC Corofil products |
|---|---|---|
| Ventilated façade with a specified 25mm open air gap | Use only where the current tested configuration matches the cavity, substrate and fixing arrangement. | COSB-25 |
| Ventilated façade with a specified 44mm open air gap | Use only where the current COSB-44 tested configuration matches the cavity, supporting construction and fixing arrangement. | COSB-44 |
| Closed / full-fill cavity barrier | Match cavity size, orientation and supporting construction to the tested detail. | Cavity Fire Stop CCFS |
| Rigid-wall / rigid-floor linear joints | Select the documented joint arrangement according to joint width, orientation, supporting construction and movement requirement. | Linear Gap Seal Strip CLGS |
| Profiled-deck / head-of-wall or specified beam-related voids | Use only within documented CLGB configurations and the applicable supporting construction and fixing arrangement. | Linear Gap Seal Block CLGB |
| Linear joints and specified penetration-seal applications | Use with the applicable substrate, joint or system arrangement in accordance with the relevant tested detail. | Acoustic Intumescent Sealant CAIS |
TECHNICAL RESOURCES
PFC Corofil Tested Details & Technical Resources
PFC Corofil provides technical support, product documentation and selection resources for cavity barriers, linear gaps and associated passive fire protection systems. Always use the latest manufacturer information for the exact cavity or joint configuration, supporting construction, orientation and fixing arrangement.
The PFC Corofil Cavity Barrier Specifier can assist with identifying potentially relevant products and system information, but it does not replace project specification, technical review or verification that the selected tested detail applies to the site condition.
TECHNICAL GUIDANCE
PFC Corofil Tested Systems and Installation Guidance
PFC Corofil passive fire protection products form tested systems. The cavity or joint type, dimensions, supporting construction, orientation, product selection, fixing arrangement and installation method all affect whether the tested detail applies.
- Identify whether the cavity is ventilated / open-state or requires a full-fill cavity barrier.
- Confirm the cavity or joint dimensions and the supporting construction.
- Identify the horizontal or vertical orientation and the required fixing arrangement.
- Select the current certified detail and follow the applicable installation instructions.
- Obtain technical support where the site condition falls outside the documented standard details rather than modifying the arrangement by assumption.
What Information Should I Provide?
For product guidance, it helps to provide the main details of the cavity, joint and supporting construction:
- Open-state / ventilated or full-fill requirement
- Cavity or joint dimensions
- Supporting construction
- Horizontal or vertical orientation
- Façade or wall build-up where relevant
- Joint movement requirement where relevant
- Proposed fixing arrangement
- Required fire performance
- Existing tested-detail reference if known
FREQUENTLY ASKED QUESTIONS
PFC Corofil Fire Protection FAQs
PFC Corofil cavity barriers are used within tested passive fire protection systems to restrict the spread of fire and smoke through concealed cavities. The correct product depends on whether the cavity is ventilated or full-fill, together with the cavity dimensions, orientation, supporting construction, fixing arrangement and applicable tested detail.
An open-state cavity barrier is designed for applications where a ventilation gap is maintained during normal service and an intumescent component closes the opening when exposed to fire. A full-fill cavity barrier fills the cavity where normal ventilation through that location is not required. Product selection must follow the applicable tested system.
COSB-25 and COSB-44 are different PFC Corofil open-state cavity barrier products intended for different documented open-gap configurations. COSB-25 should only be selected where the applicable tested detail requires that product and gap arrangement, while COSB-44 should only be used where its own tested configuration applies.
PFC Corofil linear gap seals are used in tested passive fire protection systems for specified linear joints and construction gaps. Selection depends on factors including joint position, width, orientation, supporting construction, movement requirement and the applicable tested detail.
