Flamro Mineral Fibre Board Pre-Coated with FLAMMOTECT-A

October 27, 2026

Effective passive fire protection is essential for helping prevent fire and smoke from spreading between compartments within a building. Where cables, pipes and other building services pass through fire-resisting walls and floors, suitable penetration seals are required to help maintain the intended fire performance of the construction.


The Flamro mineral fibre board pre-coated with FLAMMOTECT-A is a specialist fire protection board designed for use within approved cable, pipe and mixed penetration sealing systems.



At Blazeout, we supply passive fire protection products to contractors, firestopping installers and construction professionals, helping make it easier to source the materials required for their projects.


What is Flamro mineral fibre board pre-coated with FLAMMOTECT-A?

Flamro mineral fibre board pre-coated with FLAMMOTECTA-A is a pressure-resistant, water-repellant rock wool insulation board with a factory applied coating of FLAMMOTECT-A ablative fire protection compound.


The coating is applied to one or both sides of the board, depening on the product varient. This provides a ready-coated board for use in specified firestopping systems/


Rather than requiring the coating to be applied to the board on site, the product is supplied with its protective coating already in place. This can help simplify material preperation and support a more consistent installation process when used in accorfance with the relevant system instructions.


The board is designed to act as a system component, not as a standalone solution for every opening in a fire-resisting wall or floor. Its suitability depends on the complete penetration sealing system, including the supporting construction, services and installation details.


What is FLAMMOTECT-A?

FLAMMOTECT-A is an ablative fire protection coating used in Flamro firestopping systems.


Ablative coatings are designed to respond to fire exposure through a combination of physical and thermal processes that help protect the relevant system. The precise performance depends on the formulation and the tested configuration in which the coating is used.


When factory-applied to a mineral fibre board, FLAMMOTECT-A forms part of a fire protection system intended to help maintain compartmentation around service penetrations.


The pre-coated board is designed to be incorporated into approved systems alongside the appropriate sealing materials and other components specified by the manufacturer.


Where is Flamro pre-coated mineral fibre board used?

Flamro identifies three principle application categories for its mineral fibre board pre-coated with FLAMMOTECT-A.


  1. Cable penetration seals

Cables frequently pass through walls and floors to supply electrical power, communications and other building services.


Where these openings are located in fire-resisting construction, the penetration needs to be sealed using a suitable tested system.


Flamro pre-coated mineral fibre board can form part of an approved cable penetration sealing system, subject to the permitted cable types, opening dimensions, supporting construction and other installation requirements.


    2. Pipe penetration seals

Pipes may also pass through compartment walls and floors, creating openings that need suitable fire protection.


The pre-coated board can be used within specified pipe penetration sealing systems. The appropriate arrangement depends on the type of pipe, the supporting construction and the additional sealing components required by the system.


Not every pipe material or configuration is covered by every system, so the relevant technical documentation should always be checked before installation.


      3. Mixed penetration seals

Some service openings contain a combination of cables, pipes and other building services.


Mixed penetration sealing systems are designed for defined combinations of services passing through a shared opening. Flamro's pre-coated mineral fibre board is suitable for use in approced mixed penetration systems where the complete installation meets the applicable requirements.


This makes it important to assess the opening as a complete system rather than selecting the board in isolation.


At Blazeout, we understand the importance of sourcing suitable firestopping materials for construction projects.


As an approved distributor of Flamro products, we help contractors and firestopping professionals source passive fire protection products alongside a wider range of materials, fixings and site consumables.


Our single-source approach is designed to simplify purchasing, reduce the administration associated with coordinating multiple suppliers and help keep projects moving.
