Plenum Ceilings & Ceiling Bulkheads

Durasteel plenum ceilings combine high performance horizontal fire separation and a naturally or mechanically forced ventilation space in one single system, ensuring either supply of air or extraction of smoke remains fully functional even during a fire.

Fireproof Ceiling

Durasteel plenum ceiling systems are tested and certified for up to 4 hours fire resistance to fire attack from both above and below. The high strength and load-bearing capacity of the system permits internal loads, such as maintenance foot traffic and ventilation fans, and external service loads up to 15kN/m².

Each plenum system is designed bespoke according to performance requirements and site conditions. Typically, the system comprises 9.5mm Durasteel boards fixed to an 80mm deep steel channel framework, maintaining the overall depth of the system to less than 90mm and a weight of less than 35kg/m².

The systems are ideal as a fire-rated ceiling in power/transformer rooms and service corridors, or for the formation of smoke extraction plenums as part of a larger ventilation system, for example in underground metro systems.
