What exactly is a fire-rated doorset?

Posted on March 5, 2020 at 1:56 pm

Fire-rated doors are extremely popular in commercial and industrial requirements where the risk of a fire is deemed high, such as a restaurant or food processing facility. They can, of course, be used in a wide variety of situations though, and they are most commonly manufactured of steel. In most cases, fire rated steel doorsets will offer many hours of fire protection (usually 4 hours), meaning they will deliver FD30, FD60, FD120, FD180 and FD240 certifications. 

As mentioned, these doors are ideal for applications in commercial and industrial premises; they can also be used as a connecting door from your garage into your home, but you must understand that such quality doors do come at a price. These are going to cost considerably more than your usual door, but the strength and durability they deliver is second to none. If you’re buying a top model that’s fully certified, you will, of course, have to pay a premium; however, there are many different manufacturers to choose from. You must always, however, make sure they are compliant with fire safety regulations, as required by UK law, and they should be specially designed to slow the spread of fire in an emergency. Like most doors, they are available in a wide range of styles, so whether you love a modern grey or a bold blue, you’ll quickly find a door of the right shade for your building. 

These doors are also used for high-security locations and settings, such as data centres, banks, cash handling, pharmaceutical entities and airports. Generally, the thicker the steel, the better protection you have for longer. When you consider the bond between fire safety and wall construction, there’s one main safety issue that these fire-rated doors can address. Normal wall construction usually incorporates elements that provide some protection; whether that’s drywall, plaster, or other sorts of insulation/material. These materials will retard the expansion of the hearth for a particular period of your time. Doors and windows are a different story altogether.

They are typically the smallest amount protected component of wall construction and act as expressways for the fire to spread throughout the structure. Fire-rated doors are therefore explicitly engineered and constructed to ensure adequate containment; thus, the fire (and the damage caused) stays contained rather than spreading. Most fire rated doors use steel, however, you will also come across glass, ceramic, or other insulated metals, or perhaps even a medley of all 3!
