Passive Fire Insulation

Minimum loss, maximum protection...

Carrying out the Passive Fire insulation, has an aim to create fire barriers in order to endure the building with mechanical pressures to the possible high heat during the fire and the required functionality ensured in various areas depending on the changing details. In particular, the vertical openings (electrical and mechanical shafts) in the building passages act as natural chimneys during the fire, causing the fire to spread within seconds. Therefore, in order these openings to be isolated fire barriers must be created using special mastic, paint and mortars.

Before the construction of fire barriers, the structure should be allocated to fire zones in horizontal and vertical areas in accordance with the fire action plan of it. If no zoning is realized, the whole structure is taken as a single fire zone, so there is a possibility that the entire structure will be damaged in the event of a fire hazard. Regions, also described as fire zones or compartments, can be defined as spaces in which smoke and flame are trapped during a fire. Thanks to
These zones created using passive fire stopping products will only place the fire area at risk and stop the spread of flame and smoke for a certain period of time, rather than the entire building during the fire.

The fire is divided into two classes as hydrocarbon and cellulosic in terms of formation. Although steel surfaces offer many structural and architectural advantages, they carry risks in terms of fires that can occur in structures used as carriers. To delay reaching the temperature at which the steel starts to lose its strength is possible with intumescent and spray applications.
