  • Patent number: 10711924
    Abstract: The fire and smoke containment services transit unit includes a casing constructed from a material such as plastic or timber having a thermal conductivity of less than 5 watts per meter per Kelvin. The casing defines a first opening at a first end and a second opening at a second end. Intermediate the first and second ends is an internal volume encased by the casing. The internal volume and each of the openings and are sized to allow services such as cables, pipes, etc., to be threaded through the services transit unit. An intumescent material is housed within the internal volume. Prior to exposure to the heat of a fire, the intumescent material maintains a slim profile. When exposed to the heat associated with a building fire, the intumescent material swells and seals the internal volume against the passage of fire, smoke or heated gases through the transit unit.

The internal volume and each of the openings are sized to allow services such as cables, pipes, etc. to be threaded through the services transit unit. An intumescent material is housed centrally within the internal volume. Prior to exposure to the heat of a fire, the intumescent material maintains a slim profile. However, when the transit unit is exposed to the heat associated with a building fire, it swells and thereby seals the internal volume against the passage of fire, smoke or heated gases through the transit unit.
