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.
