A fire door is a door with a fire-resistance rating used as part of a fire protection system to reduce the spread of fire or smoke between compartments and to enable safe exit from a building or structure.
As well as ensuring the door is hung properly, it is also very important that where a fire door is installed, any gaps left in the opening between the wall and the door frame must be properly filled with an intumescent strips or seal. Fire doors should only be installed by a qualified carpenter or building contractor.
Fire stopping and penetration sealing is the process of preserving the fire resisting performance of walls, floors and roofs where voids exist or services have been installed.
Fire Stopping is vital to the stability and integrity of a building or structure in case of fire. A building is separated into manageable areas of risk (Fire Compartments) by the use of passive fire protection measures which have proven fire performance properties. These fire stopping measures are designed to restrain the growth and spread of fire, allowing the building occupants time to escape safely. It is paramount that any gaps in these fire resisting constructions are sealed to ensure the system works to it's maximum ability. Such gaps are typically at service penetrations through walls and floors
This fire protection for penetrations passing through floors, walls, ductwork etc., can provide up to four hours fire resistance.
