Flamro Cable Tubes

October 26, 2026

Cables and electrical services frequently pass through walls, floors and other building elements. Where these elements form part of a fire compartment, the openings must be appropriately sealed to help maintain the required fire resistance.


Flamro Cable Tubes provide a specialist solution for certain cable penetration sealing applications.


What are Flamro Cable Tubes?

Flamro cable tubes are fire protection devices designed to seal suitable openings containing cables, cable bundles or electrical installation conduits.



The tubes incorporate an intumescent lining. When exposed to fire, the material expands to help close the opening in accordance with the performance of the relevant tested system.


Some designs comprise two halves, allowing installation around existing services where the applicable system permits this arrangement.


Where are Flamro Cable Tubes used?

Depending on the particular product and appoved configuration, cable tubes can be used in specified penetration sealing systems in walls and floors, including certain raised access floor applications.


They can be useful where electrical services need to pass through a fire-resisting element while allowing for an organised service installation.


Before selecting a cable tube, check the cable types, opening dimensions, supporting construction and required fire-resistance performance against the relevant documentation.


What should installers consider?

Correct selection and installation are essential. Check the permitted service occupanyc, substrate, tube dimensions, installation orientation and any requirements for complementary sealing materials.

Choosing the right fire protection coating is an important consideration for projects where building services and structural elements require protection as part of a specified passive fire protection system. Flamro provides a range of fire protection products, including specialist coatings and fillers designed for defined applications. At Blazeout, we help contractors and firestopping professionals source products to meet their project requirements.  What are Flamro fire protection coatings? Fire protection coatings are specialist materials used within particular fire protection systems. Their purpose and performance depend on the formulation, the substrate being protected and the system in which they are installed. Flamro's product portfolio includes a fire protection coating, which is used in specified fire protection applications, including certain cable protection systems. It is important to distinguish between coatings intended for cable installations, coatings used with mineral fibre boards and products designed for other applications. These products should not be treated as interchangeable. Where can Flamro coatings be used? Depending on the specific product and tested system, applications may include: Fire protection for suitable cable installations Coating components of specified firestopping systems Use with compatible mineral fibre board systems Selected passive fire protection applications in buildings and infrastructure The exact permitted uses, application thicknesses, drying requirements and performance ratings must be confirmed from the manufacturer's documentation. Why specify the correct coating? A coating must be compatible with the substrate and the intended fire protection system. Application method, coverage, thickness and installation conditions can all affect the final result. Installers should always follow the relevant technical data sheet and installation instructions rather than relying on a generic description of a fire protective paint.
