why smoke seal is compulsory on fire doors

Smoke seals are compulsory for fire rated doors because they help prevent the spread of smoke during a fire. Fire rated doors are designed to resist the passage of fire and smoke for a specified period of time, typically 30 minutes to 360 minutes. However, without a smoke seal, smoke can still pass through the gaps around the door, reducing the effectiveness of the fire rated door and putting people's safety at risk.

In addition, smoke is a major cause of death and injury in fires, as it can quickly fill a room and reduce visibility, making it difficult for people to escape. By preventing the spread of smoke, smoke seals can help give people more time to evacuate and reduce the risk of smoke inhalation.

Building codes and fire safety regulations often require the use of fire rated doors in certain areas of a building, such as staircase and corridors, to provide safe means of escape during a fire. These codes also require that fire rated doors be equipped with smoke seals to ensure their effectiveness in preventing the spread of smoke.

Smoke seal can be used on fire metal doors and wooden fire rated doors and metal acoustic doors etc.

Smoke seal is a mandatory part for fire doors but still few companies ignore this due to increasing cost of product but we suggest its should be applicable on every door to reduce big disasters.For more blog click on
