    Fire resistance

    We offer you the best flue solution for any application.

    Fire resistance

    Modular fire resistant flue and ventilation pipes

    The classifications of fire resistance in pipes are not based on the resistance of the pipe itself in case of fire but on maintaining the sectorization of fires in the buildings.

     

    The buildings are divided in different sectors of fire and depending on the level of risk of each sector its walls and ceilings must have different levels of fire resistance to prevent a fire in the risk sectors to get transmitted to the adjacent sectors. The ducts are installations that run through different sectors of fire, which is why they are potential elements of fire transmission between sectors.

     

    All standard twin wall insulated chimney systems of Jeremias are 4-hour fire rated under the BS 476 part 20 for chimneys

     

    Besides this 4-hour fire rating chimney systems Jeremias offers also three different fire rated ducting systems. The resistance to fire of the ducts is precisely the ability of these ducts to prevent such transmission of fire between various sectors through which they run, regardless of the fact that after the fire the duct itself may not be usable again. These fire resistances are measured in minutes, which is the time during which it is guaranteed that the ducts will not transmit the fire. A duct with classification EI30, means that for at least 30 minutes it is guaranteed that the duct will not transmit a fire produced inside it.

     

    Jeremias offers a complete range of pre-fabricated modular ducting systems to install for exhaust gas and extract that need to be fire rated in accordance with various international standards.

    • The DW-ECO EI 30 modular ducting system has 30 minutes fire rating and is specially designed for non-domestic kitchen extract, mainly in restaurants or convenience food factories. Accessories such as inspection doors for maintenance and cleaning purposes are included in this system.
    • The SV-EI 60 modular ducting system has  60 minutes fire rating and is normally used for the basement and enclosed car park ventilation systems. It is suitable for clearing smoke and fumes with natural or mechanical methods.
    • The SV-EI 120 modular ducting system has 120 minutes fire rating for high risk areas. The duct must retain fire rating for the same period of time as the compartment through which it passes.
