  • The material it is built from
  • The fire-resistance rating it provides
  • The overall product design
  • The manufacturer

Typically, the higher fire-rated doors cost more as they give better protection and last longer. However, any given manufacturer can set a higher price if they think their doors have additional features or use a specific combination of materials, or have a more appealing design.

To give you a better understanding of cost range here are couple of examples:

  • Solid Steel door with 1.5 hour rating: $400
  • Solid Timber door with 30 Minutes rating: $140

Don’t forget that fireproof doors also require proper installation. If done wrong the fire rating stated for the product may be compromised and cannot be fully relied on. The installation is usually done by a carpenter or a trained specialist. So you should add the cost of installation as well. The price tag normally starts at $500.

USA and EU have their own fire test standards, which must be met by certified manufacturers. This certification is the direct indication of what you can expect from the specific door.

Heavy duty steel doors normally provide higher fire rating – up to 4 hours. Timber doors bear lower ratings: usually 20-60 minutes.

Important note: The door itself and its connected parts (an intumescent strip for example) have independent ratings as they are made of different materials.
