Nullifire FV060 Ventilated Facade Cavity Closer fire barrier provides fire protection for cavities in a rain-screen cladding system, maintaining compartment lines to the exterior of a building. The design leaves a gap for free airflow movement and the drainage of moisture, preventing mould growth and dampness within the cavity, with a polymeric encapsulation ensuring pooling water does not remain on the face of the Rainbar.
Made from a high pressure graphite-manipulated intumescent composite contained within a waterproof seal, the Rainbar cavity barrier expands across a cavity when attacked by fire, sealing up gaps and maintaining fire integrity for up to 60 minutes. By slowing down the spread of fire more time may be allowed for evacuation, potentially saving lives, and preventing further cosmetic or structural damage to buildings.
The simple fixing system allows for speedy installation on site. Rainbar is both lightweight and durable and requires no further maintenance and requires no further sealing.
- Ultra-slim design ensures easy installation in awkward situations
- Fully tested at Exova BM TRADA up to 60 minutes integrity
- Lightweight and durable
- No maintenance, no further sealing required
Fixing centres may not exceed 400 mm. Joint to joint fixing centres may not exceed 400 mm and may not be less than 100 mm from the joint.
All pieces exceeding 600 mm require a minimum of 3 fixings.
Minimum fixings cut pieces 300 mm - 600 mm = 2 (100 mm from joints). Smaller pieces always require two fixings at equal distance from the centre line.
Fixings should be located centrally through the depth of the product +/- 5mm to the centre line.
