Textile fire barriers or curtains are made of a fireproof material that spreads itself in case of fire simply by gravity thanks to a counterweight. Normally they are fully hidden in a galvanized steel case.<\/p>\n

Unlike smoke containment barriers<\/a>, which we talked about in a previous post<\/a>, these textile fire curtains completely close the space we want to sectorize. Lateral guides on both sides of the textile prevent it from moving off its tracks when submitted to the pressure generated by a fire and guarantee the textile to remain smoke and flame proof during a specified period of time.<\/p>\n

Although, for safety reasons in case of a lack of light, the deployment of the curtain is only happening thanks to a counterweight attached to the bottom part of the textile, the curtain is equipped with a motor allowing it to be easily put back up in its steel case in case of a false alert or a test.<\/p>\n

Fire curtains are required to meet precise standards of integrity<\/strong> \u201cE\u201d<\/strong> during a period of time determined by standard tests, and of insulation \u201cI\u201d<\/strong> given that, during a fire, the textile becomes incandescent and emits thermal radiations on the other side of the sectorization.<\/p>\n

CURTAIN COMPONENTS :<\/strong><\/p>\n

    \n
  • GCP<\/strong>: Control box in charge of receiving the fire signal coming from the detection system and, consequently, activate the barrier. The control box allows us to know the system status and assess the needs for maintenance. It counts with a system of batteries able to maintain the curtain and the electro valves in rest position if the electrical supply were to fail<\/li>\n
  • MCC<\/strong>: Motor control module. Located next to the motor, it ensures the stability of the curtain in rest position, synchronises its speed when putting it back in its case and limits its speed when going down.<\/li>\n
  • Case<\/strong>: The case contains the fire barrier. It is made of 1,5mm thick galvanised steel. It counts with several configurations and several support systems to adapt to the architectural conditions of each project.<\/li>\n
  • Lateral guides<\/strong>: Made of 2mm thick galvanised steel, they fix the curtain laterally so that it maintains its compartmentalisation function despite the pressure generated by the fire.<\/li>\n
  • Closing profile: <\/strong>Located on the bottom part of the textile, it ensures the stability of the curtain and serves as closing element for the steel case when the curtain is in rest position.<\/li>\n
  • Textile<\/strong>: Fabric made of fibreglass. It is conceived to resist to high temperatures up to 1000\u00baC.<\/li>\n
  • <\/li>\n<\/ul>\n

    mercor tecresa\u00ae <\/span><\/strong>manufactures two types of curtains:<\/span><\/p>\n

      \n
    • The FC 2<\/strong> type with a classification of EW 60<\/strong>.<\/li>\n
    • The FC 4 type with an aluminium foil and a classification of EW 120<\/strong>.<\/li>\n<\/ul>\n

      \"\"Standard test for FC 4 sectorizing curtains.<\/strong><\/span><\/p>\n

       <\/p>\n

      These curtains are tested according to the European standards and their classification depends mostly on their dimensions. The letters EW<\/strong> mean that the fire curtain is required to remain intact without passage of flames or smoke, and its thermal radiation must be inferior to 15 KW\/m2<\/sup><\/strong>.<\/p>\n

      In the next graph, we see the distance the evacuation ways and flammable objects need to be at, so that the thermal radiation they undergo does not go over 180 \u00baC <\/strong>in the case of our FC 2 type <\/strong>fire curtain:<\/p>\n

      \"\"<\/p>\n

       <\/p>\n

       <\/p>\n

      By maintaining these distances, which also depend on the curtain size, we can precisely determine the installation required to respect the current regulations.<\/p>\n","protected":false},"excerpt":{"rendered":"
