PMA Fire Barrier Solutions
PMA can now offer a number of different solutions allowing cables and wires within a cable protection system to be fed through a firewall without loss of integrity.
- Full Description
PMA and Roxtec have cooperated to design a system allowing cables and wires within a cable protection system to be fed through a firewall without loss of integrity.
The system must seal all openings and joints preventing the spread of fire and dangerous gases for a sufficiently long period of time to allow evacuation.
In the combined solutions PMA conduits, fittings and specially designed wall transit adapters are combined with a Roxtec sealing module to provide a system offering protection against the spread of fire from one compartment or room to the next.
The PMA fire barrier adapters use an intumescent material fixed within the adapter to block the transport of fire, heat and fumes in the event of a fire. The material expanding to fill the cavities between the cables within the adapter.
Intumescent materials (typically sodium silicate or graphite) swell as a result of heat exposure to many times their original volume. This characteristic can be used very effectively to seal cavities preventing heat, fire and gases from passing through.
