How do Fire doors work?
Fire doors must be installed according to a particular set of instructions for them to do their job. Firstly, intumescent strips must be used when installing a door because these intumescent strips expand when exposed to heat, effectively sealing gaps between the door edges and the frame. This helps in keeping smoke out, which is one of the main reasons for deaths during a fire.
The door frame should also adhere to safety restrictions allowing the door to stand in case of fire, and not crumbling under heat.
Why do you need Fire doors?
Fire doors are a passive form of protection and battling against fire. It is one of the best features you can invest in for your house or office. Fire doors can be helpful to keep possessions and personnel safe until an escape route is created from a burning building. These doors are not entirely fireproof, which is why they can be used for momentary protection only as they will burn eventually. They will only slow down a fire for a specific period. But in most cases, even that is enough, contained fire and smoke allows time to escape safely.
