Fire Protection and Fire Partitioning Insulation Solutions
A fire in a building can lead to serious loss of life and property. Insurance companies pay about half their annual payments for fire damage. Water damage amounts to about 30 % and burglary to 20 % of annual claims. Buildings as well as their contents contribute to the spreading of fire. With the right fire protection, the risk of fire can be considerably reduced.
Fire protection in a building is divided into two types: active and passive. Active fire protection operates when a fire breaks out, and includes detection and alarm systems, automatic sprinklers, fusible link doors and shutters, emergency lighting and smoke ventilation systems. Rendering this system inoperative is relatively easy: vandalism of the water feed mechanism, damage to the operating valves, or simply ignorance will all harm it. A building with truly effective fire defence therefore needs more than one fire protection system.
Passive fire protection is generally built into the structure so that the building can withstand fire for a specified period. Passive fire protection protects the structure and the lives of people inside the building in a fire by reducing or preventing the fire from spreading internally and externally fire, thereby maintaining the stability of the building and the safety and escape routes for the occupants.
Passive fire protection includes compartmentalisation and structural fire protection, good access to buildings for firefighters, and safe and effective means of escape.
What building materials you choose and how you use them to provide the required level of passive fire protection depends on two factors: their reaction to fire and their fire resistance.
With its high melting point, we provide an ideal material for fire protection applications that retains its properties even at temperatures as high as 1000ºC. We have excellent fire solutions for all different kind of buildings and applications.
Fire partitioning walls are typically constructed of plaster board partitions. Fire-rated partitions are internal walls that provide vertical fire separation in structures such as dividing walls. These walls are typically non-load bearing. A fire-rated partition is a partition for which the fire resistance performance has been determined according to the appropriate Singapore standards. Similarly, the reaction to fire performance of the exposed surfaces is also determined by the appropriate fire test standards. The requirement to determine the fire resistance and the reaction to fire performance of a partition is stated in current building regulations.
Partitions may be constructed in a variety of ways and the designer’s specification will depend on the intended use, performance levels and the standards of finish and appearance required. Partitions may be formed from various types of sheet materials, supported by and concealing timber or metal stud framework, with or without expressed/ featured joints. They may also be constructed by using composite panels supported by an exposed framework, or prefabricated panels, butted together in floor and head tracks, with or without a supporting frame.
Once a fire has become fully developed it attacks the structure of the compartment and tries to spread beyond the compartment of origin. A fire-rated (fire-resisting) partition prevents this by creating a structure (i.e., a compartment) which does not collapse and contains the fire for a given period of time. It is necessary to determine the fire resistance of the partition by assessing the behaviour when subjected to defined heating and pressure conditions, which may be encountered in a fully developed fire.
Fire resistance tests employ a standard temperature/time curve, and pressure distribution for this purpose. The fire resistance of such partitions ranges from 30 to 240 minutes (or more).
Encapsulated with a pink lining paper, FireLine® gypsum boards are built with a specially formulated core ingredient that allows the boards to stay integrated despite high temperatures. A mixture of gypsum compound, fibreglass and micro silica, FireLine® is also used as protection for structural steel.
FireLine® is designed to withstand high levels of fire exposure in critical areas within a building. It is universally used in wall and ceiling systems that form a fire compartment element providing the required fire resistance limit.
