How can a fire-rated door help during a fire?

A fire-rated door — or fire-resistant door — is specially constructed to slow or prevent the spread of fire and smoke, more commonly in commercial buildings than in residential structures.

Fire-rated doors can help slow or prevent the spread of fire and smoke, but  they are not designed to be completely fireproof. These doors are made of combustible materials and will eventually burn through in a fire. However, they will resist the penetration of heat and flames to slow the fire for a specified time period.

And by containing the fire and smoke, they provide additional time for you to exit the structure. Most people focus on the element of fire, and they don’t underestimate the significance of reducing smoke inhalation. However, the majority of people who die in residential fires do so as a result of smoke inhalation.

Fire-rated doors may also help to protect property and personal assets while firefighters work to extinguish the fire.
