Why install an elevator shaft smoke guard?
When a fire breaks out in a building, the main priority is to prevent loss of life and the biggest life-threatening danger is smoke, not the actual fire. More fire deaths are attributed to smoke than fire burns each year.
One of the biggest concerns in stopping the spread of smoke
The International Building Code (IBC) is the most widely adopted building code in the US. The IBC, as well as the NFPA elevator code, specifies safety requirements for keeping buildings safer during a fire. Their requirements specify an elevator lobby, an area around the elevator opening that can be sealed off with elevator smoke doors.
Elevator lobby pros and cons
Elevator lobbies not only help save lives, but they are required in all buildings where an elevator shaft enclosure connects more than three stories. An elevator lobby must be constructed with one-hour rated firewalls and doors with a minimum of a 20-minute fire rating.
- Helped provide a fire barrier and smoke guard
- Take up valuable building space
- Add additional building costs
Most architects find designing elevator lobbies with bulky elevator smoke doors far from ideal. Architects would rather use that dead space to add more room to the overall floor plan, which in term could provide more revenue to a building owner.

Other fire and smoke guard alternatives
The IBC code allows for seven different exemptions to the fire lobby requirements.
Some of those exemptions include:
- Automatic sprinklers
- Unenclosed elevators
- Magnetically released fire swing doors
- Pressurized elevator shafts
- Automatically deploying smoke curtains
Every possible alternative means of having to incorporate an elevator lobby room is not covered in the code, yet one of the most effective alternatives is to provide an automatically deploying smoke curtain. A smoke curtain provides a sealed smoke guard to prevent smoke and soot from entering the elevator shaft. Our SmokeShield Elevator Smoke Curtain provides such a smoke guard in only 10” of headroom as opposed to the couple hundred square feet a hotel lobby occupies.
SmokeShield Elevator is the perfect smoke protection for buildings
With nearly 100 years of life safety and fire protection product experience, our hoistway smoke guard curtain makes is possible to eliminate the IBC elevator lobby requirement, allowing architects and designers additional room for a more spacious layout.
First and foremost, keeping a tight seal is paramount to prevent smoke from migrating up the elevator shaft to other floors. Magnetic seals can fail if the smoke curtain is pulled too aggressively from the elevator door perimeter once deployed into position. Only SmokeShield Elevator has the patented GuideLock™ technology that positively re-seals the hoistway after the smoke guard curtain is in position.
