A fire door is a fire resistant entrance to a flat that leads to shared or communal areas within a building. Fire doors are installed to prevent a fire inside of a flat spreading to the communal areas and escape routes within the building. Fire doors can also stop a fire in the communal area of the building spreading into individual flats.
A fire door is usually the front entrance to a flat, however some internal doors such as a kitchen door can also be a fire door.
The current Building Regulations, Approved Document B, specify that front doors of purpose built flats should be fire doors that offer a minimum of 30 minutes’ fire resistance.
