What is a fire rated garage door?

A fire rated garage door is a commercially engineered door that has been rated and UL listed to not let fire breach through for up to 4 hours. In the event of a fire, fire doors are triggered to close and prevent fire and smoke from spreading. They are designed to protect the means of egress, which is a specifically designed continuous unobstructed path of exit. The means of egress are specifically designed, usually by the architect or designer to have a plan of escape in the case of a fire event. At least two separate means of egress or exit paths are required. Fire rated garage doors are one solution to prevent fire or smoke from blocking or preventing the exit route.

Why use fire rated doors?

In today’s business world, many flammable products, materials, solvents and more are used and stored in buildings and facilities. Additionally, many processes and manufacturing techniques can have flammable properties. Even accidents, poor craftsmanship or carelessness can lead to a fire event. When a fire event happens, it is important to protect fire and smoke from intruding upon the evacuation route, or means of egress, so that everyone can exit safely. To do this, rooms and areas that have higher chances of fire events will have fire rated garage doors, fire rated shutters and other means of containing fire installed.
