Rapid response and enhanced performance

The Extended Corridor System aids fire-fighters by allowing the corridor to be cleared of smoke rapidly, even during the later stages of a fire, when a conventional system might well be overwhelmed.

It allows safe escape conditions to be maintained in the corridor, even when the travel distance is extended by a factor of 2 or 3 in one direction. This can remove the need for an additional staircase, freeing up typically as much as 38m² of additional saleable or lettable space per floor.

The Extended Corridor System out-performs the conventional solution for both evacuation and fire-fighting.

The Extended Corridor System is generally unaffected by external wind pressures, so is inherently more reliable than a natural system.

The Extended Corridor System achieves exceptional smoke extraction performance by utilising a corridor extraction system (corridor ventilation system) at one end of the corridor and a dedicated air inlet system at the other.

There are four types of Extended Corridor System:

(a) Pull system – mechanical extract / natural inlet – outlet

(b) Push system - mechanical extract / natural inlet

(d) Push-pull reversible - balanced system but with added flexibility.
