Smoke Seal

Smoke Seal

A smoke seal is a crucial component of a fire-resistant door assembly that helps prevent the spread of smoke and fire between compartments or rooms. Its main function is to create a barrier that restricts the flow of smoke and other harmful gases in the event of a fire.

Below are the features and functions of a smoke seal that help prevent the spread of fire and smoke:

  • Material: Smoke seals are typically made of a fire-resistant material such as intumescent rubber or silicone. These materials expand when exposed to heat, creating a tight seal between the door and the frame.
  • Location: Smoke seals are located around the perimeter of the door, between the door and the frame. The seal may be in the form of a gasket, strip or brush, depending on the design of the door.
  • Compression: The seal is designed to compress when the door is closed, creating an airtight seal that prevents smoke and gases from passing through.
  • Smoke and Fire Resistance: Smoke seals are rated based on their ability to resist smoke and fire. They are tested under various conditions, including temperature, pressure, and smoke infiltration, to ensure that they provide adequate protection in the event of a fire.
  • Code Compliance: Smoke seals must comply with local building codes and standards to ensure that they meet the minimum requirements for fire and smoke resistance.

In summary, a smoke seal around a door serves as a vital barrier that restricts the spread of smoke and fire between compartments or rooms. Its features, including material, location, compression, smoke and fire resistance, and code compliance, are critical to its effectiveness in preventing the spread of fire and smoke.
