Also to achieve the same fire resistance in terms of integrity, and if required insulation, as required for the compartment walls or floors.
  • Smoke duct systems - to prevent the transmission of smoke and combustion products from a fire zone, and to control the pressurising and excess air relief within pressurisation systems.
  • Smoke curtains - to create a smoke reservoir by containing and limiting the travel of smoke; to channel smoke in a predetermined direction and to prevent or retard smoke entry to another area or void.
