Smoke Stratification occurs when a layer of warm air (a Stratus) collects at roof level. As smoke from a fire low-energy fire rises, it reaches this thermal barrier and lacks the energy to rise further. This causes the smoke to build up below the level of the stratus, creating a smoke plateau (see diagram below).
Stratification generally effects high-level buildings such as Atriums, Aircraft Hangers, Warehouses and Waste Management Facilities. Click Here to view our recent website blog on Stratification.
