FV050 Small Ventilated Cavity Barrier
Colour: Silver
Product Dimensions: 6 x 75 x 1000 mm (T x H x L)
FV050 Small Ventilated Cavity Barrier is suited to an open state cavity of up to 50 mm, manufactured from a directionally expansive intumescent material encapsulated in a foil barrier.
Usage:
FV050 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. In the event of a fire FV050 will expand to close the external wall cavity, providing effective fire resistance, for integrity and insulation for up to 120 minutes depending upon the construction of the external walls. FV050 is designed for use within a 50 mm cavity, and once installed will close the remaining free air gap (in front of the 6 mm thick cavity barrier) of 44 mm.
Safety data sheet must be read and understood before use.
Fixings / Application Instructions
- Affix the product using 5 mm Ø stainless steel screws or nails at a maximum spacing of 250 mm using a maximum countersunk head size of 16 mm. Position of first screw should be maximum 125 mm from one end, maximum 250 mm centres (4 screws per linear meter). When less than 1 meter, fixings should be positioned at maximum 125 mm centres. For lengths less than or equal to 250 mm in length, a minimum of 2 fixings are required.
- Tighten any fastenings until the head is just touching the product, it should not be overtightened as this may damage the strip.
- When attaching to a solid substrate ensure that the fixings are along the centre line of the fire barrier and the labelled side is facing out into the cavity. (So that you can read the label once the fire barrier is installed)
- If adding additional lengths, ensure they are tightly butted up against each other
