Fire ResistantDuct Work

One of the most important factors taken into consideration when designing and constructing a building is effective compartmentation to limit fire spread throughout the building. Under normal circumstances compartmentation is maintained by fire dampers within ductwork systems. Ductwork systems which do not normally contain fire dampers are as follows:

  1. Smoke Extract Ducts.
  2. Pressurization Ducts.
  3. Car Park Extract Ducts.
  4. Kitchen Extract Ducts.

FLAME BAR Fire Duct is constructed from galvanized sheet steel manu- factured to an enhanced standard, then degreased and factory fire sprayed with FLAME BAR which is a specially formulated water based com- pound. This contains selected mineral filters in a low permeability elastomeric binder to a thickness of approximately 0.7 to 1 mm to give a finished product which has been successfully tested for international use under Cellulosic Fire Conditions in excess of 4 hours duration.

The unique properties of FLAME BAR has enabled us to design a low density, highly durable material which accommodates induced stress arising from extreme and varying conditions e.g. Climatic Moisture and Structural Loading Variations, and the effect of thermal shock during a fire.
