FV065 Small Ventilated Cavity Barrier Roll is a fire rated product designed to be used as a cavity barrier up to 65 mm cavity within external walls. The product is encapsulated in a polythene barrier and made from a flexible intumescent material allowing it to be provided in a roll format.

Fire Rating: 60 Minutes

Usage/purpose

FV065 is used within external wall cavity, to reinstate fire resistance performance, of ventilated cavities, for up to 60 minutes for cavity widths of up to 65 mm, in fire conditions. The product will 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. In the event of a fire FV065’s intumescent material will expand to close the external
wall cavity, providing effective fire resistance, for integrity and insulation
for up to 60 minutes depending upon the construction of the external walls. FV065 is designed to close off a total cavity of 65 mm which allows for building tolerances of up to 15 mm (above the typical maximum cavity ventilation requirements of 50 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.

Safety data sheet must be read and understood before use.
