Rainbar

Accessories

Use Firetherm Rainbar Pro within rain screen cladding for up to 60 minutes of fire protection in cavities. This cavity fire barrier helps maintain compartment lines to the exterior of the building envelope, lying dormant until attacked by fire, when its intumescent-coated facing expands to seal up gaps, preventing the spread of smoke and fire to up to an hour.

Comprising of an engineered, powder-coated and galvanized steel carrier, the carrier retains a high-pressure graphite manipulated intumescent composite that expands in a fire to seal a maximum 100mm gap. Rainbar Pro is quick and easy to install on-site and is extremely durable, giving a service life equal to that of the building with no requirement for maintenance, unless physically damaged. The simple fixing system allows for free-flow air movement and the drainage of moisture, preventing mould growth and dampness within the cavity.
