Do exterior doors need to be fire rated

Yes, exterior doors need to be fire rated. Fire ratings are a safety measure that ensures your door will not only withstand fire but also protect you and your family from the flames.

The reason for this is that fire-rated doors will last longer than non-fire-rated doors. They are more resistant to heat, flame, and smoke, and can withstand more stress than non-fire-rated doors.

If you have an older home or one that was not built with fire protection in mind (like a new-construction home), you may want to consider replacing your old exterior doors with new ones that are fire rated.

A good way to check if your door is fire rated is by looking at the label on the inside of the door frame. If it says “Fire Protection Required,” then it’s likely that your door is not fire-rated.

Residential fire-rated door requirements

Do exterior doors need to be fire rated

Residential fire-rated doors are designed to withstand a fire for up to 30 minutes before the door is compromised. The door must be able to maintain its integrity under the effects of heat, smoke, and flames.

Also, the door should not bulge outwards when subjected to heat and pressure from flames, which could cause it to collapse. Furthermore, residential fire-rated doors are designed to withstand fire in the home. They have been tested by Underwriters Laboratories (UL) and meet specific requirements that ensure they can keep out burning debris, flames, and smoke.

Fire-rated doors are made with a minimum of three layers of material:

  1. An outer layer that is fire-resistant (such as vinyl or polyurethane). This protects the door from damage and helps prevent heat transfer from the door to the frame or other nearby materials.
  2. A core layer composed of one or more core materials, such as steel or aluminum, which provide structural support for the door assembly and protect against fire.
  3. A middle layer composed of two or more middle materials, such as fiberglass mats (for example) that provide a smooth surface for filling gaps between the core and outer layers during fabrication processes such as molding and extrusion operations.

Are residential doors fire rated?

Residential doors should come fire rated but unfortunately, not all of them are fire rated. Fire-rated doors are a requirement for most new homes, and they’re particularly important in places like high-rise apartment buildings or schools that require additional safety measures.

In these environments, it’s important that the door can withstand an external fire while keeping occupants safe inside the building.

The testing process is quite extensive, but it involves subjecting the door to extreme temperatures and pressure. The manufacturer must ensure that the door can withstand both external forces and internal fires simultaneously without sustaining any structural damage.

In addition to meeting fire-rated standards, residential doors should also have a minimum rating for wind protection in order to keep smoke out of your home during an emergency situation.
