Fire doors are a critical component of passive fire protection systems in residential, commercial, and industrial buildings. Designed to prevent the spread of fire and smoke, fire doors help protect occupants, provide safe evacuation routes, and minimize property damage during a fire emergency.

What Is a Fire Door?

A fire door is a specially constructed door assembly that resists fire and smoke for a specified period, typically 30, 60, 90, or 120 minutes. Fire doors are manufactured using fire-resistant materials and are tested according to recognized safety standards.

Types of Fire Doors

Fire doors are available in various designs to meet different building requirements:

• Steel Fire Doors
  Commonly used in industrial and commercial buildings for high durability.
• Wooden Fire Doors
  Used in residential and office spaces with fire-rated cores.
• Glass Fire Doors
  Provide fire resistance while maintaining visibility and aesthetics.
• Single & Double Leaf Fire Doors
  Designed for different opening widths and traffic flow.

Key Components of Fire Doors

A complete fire door assembly includes:

• Fire-rated door leaf
• Fire-resistant frame
• Intumescent seals
• Smoke seals
• Fire-rated hinges and hardware

Each component works together to ensure effective fire resistance.

Importance of Fire Doors

Fire doors offer multiple safety benefits:

• Prevent the spread of fire and smoke
