FV025 Small Ventilated Cavity Barrier

FV025 Small Ventilated Cavity Barrier is suited to an open state cavity of up to 25 mm, manufactured from a directionally expansive intumescent material encapsulated in a foil barrier.

Usage/purpose

FV025 is a fire rated product designed to act as an external wall cavity barrier at the required locations such as compartment
floors, around windows, doors, etc. and within uninsulated cavities requiring permanent (open-state) ventilation, to reinstate fire resistance performance. In the event of a fire FV025 will expand to close the external wall cavity, providing effective fire resistance, for integrity and insulation for up to 60 minutes depending upon the performance ability of the external walls. FV025 is designed for use within a 25 mm cavity, and once installed will close the remaining free air gap (in front of the 4 mm thick cavity barrier) of 21 mm.

Always read SDS, pre-application guidance and relevant application detail prior to application. Ensure the latest documents are downloaded prior to every project commencement.

Intumescent cavity barriers are tested and designed to expand outwards, from the face of the intumescent material only, additional design details will be required to account for external corners.
The cavity barrier should not be penetrated by anything other than the mechanical fixings which are used to fix the cavity barrier to the building.
The cavity barrier should be installed onto a flat surface, with no gaps behind the cavity barrier, the maximum space in front of the cavity barrier should not be greater than 21 mm.
Our technical support should be consulted in any instance where the principal designer is uncertain as to any issues which may impede the ability of the cavity barrier to perform as expected.

Safety data sheet must be read and understood before use.
