Atrium Chimneys & Fire & Smoke Curtains

There are numerous office blocks and department stores that have impressive open atria designs spanning over many floors. To prevent the spread of smoke and fire from one floor to another and to facilitate the rapid extraction of smoke many of these use a roof level access system complemented by an inlet make up air facility and deployment of BLE Curtains around the perimeter edge. Sophisticated control systems allow for the curtains to facilitate these strategies by employing staged and separate deployments, level by level or even curtain by curtain, with multiple alarm inputs being reacted to.

Can Fire & Smoke Curtains Be Used In Elevator Lobbies?

While BLE Smoke & Fire can offer a smoke sealed curtain for the immediate face of any elevator door this may not suit the building fire strategy. It may be required to create a protected lobby in front of a bank of elevator doors. Where this would previously have required the construction of a physical fire and smoke rated partition, a three sided lobby can now be produced using curtains. Again, when not in use there is not physical impediment or restriction but once required a full integrity and, if required, smoke sealed lobby can be created.
