Tested under UNE EN 1366-1<\/strong> standard. Fire resistance tests in service facilities. Part 1. Ducts. Classification according to UNE EN 13501-3<\/strong>: EI- 120 (ve, ho i\u2194o) S (Type A and B horizontal and vertical configuration).<\/div>\n
<\/div>\n
Tested under UNE EN 1366-8<\/strong> standard. Fire resistance tests in service facilities. Part 18. Smoke extraction ducts (multi compartment) classification according to UNE EN 13501-4<\/strong>: EI-120 S 1500 (Type C).<\/div>\n
<\/div>\n
The regulatory requirements demand the compartment of elements when traversed by installations, such as pipes or extraction and ventilation ducts.<\/p>\n
\"\"<\/p>\n
The Technical Building Code states in its Basis Document in case of fire SI 1, Interior Propagation, Section 3, Point 3:<\/div>\n
    \n
  • Fire resistance required to the fire compartment elements must be kept on the points where such elements are traversed by installation materials, such as cables, pipes, ducts, ventilation ducts, etc. To that end, a choice can be made between the following alternatives:\n
      \n
    • Put an element which, in case of a fire, automatically blocks the cross section and guarantees in such point a fire resistance at least equal to that of the traversed element, for example, an automatic firewall dumper. The t (i\u2194o) being the fire resistance time required to the traversed compartment element, or a blocking intumescent device.<\/li>\n
    • Crossing elements which provide a resistance at least equal to that of the traversed element, for example, EI ventilation ducts t (i\u2194o)
      \nbeing t the fire resistance time required to the traversed compartment element<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n
      From the previous paragraph follows that the fire resistant ducts which pass through fire compartments must have the compartments from within and from the outside to it.<\/p>\n
      RSCIEI describes in its annex II Article 5.7:<\/p>\n
      \n
      \u201cSystems including ducts, both verticals and horizontal, which traverse compartment elements and whose function doesn\u2019t allow the use of dampers (smoke exhaust, ventilation of evacuation routes, etc.), must be fire resistant or adequately protected throughout its route with the same level of fire resistance than the traversed elements, and tested according to the applicable UNE-EN
      \nstandards\u201d.<\/p>\n<\/blockquote>\n
      UNE EN applicable standards, as they appear in Annex DB SI G of the TBC are:<\/p>\n
        \n
      • UNE EN 1366 Part 1 for ventilation ducts.<\/li>\n
      • UNE EN 1366 Part 8 for multi-sector extraction ducts.<\/li>\n<\/ul>\n

        Description of Assembly<\/h2>
        <\/div><\/div>[vc_column_text]<\/p>\n
        Duct composition:<\/strong><\/p>\n
        Duct consisting of Tecbor\u00ae boards 30 mm thick.<\/p>\n
        Fixings between sections:<\/p>\n
        Longitudinally, the boards are joined with Tecsel\u00ae adhesive.<\/p>\n
        Transversally, duct sections are joined with perimeter joint covers formed by Tecbor\u00ae boards of 30 mm thick and 250 mm wide.<\/p>\n
        The joint covers are fixed to the section with 2 lines of 5 x 60 mm threaded wood screws, screwed every 250 mm on the long sides and 200 mm on the short ones. Lines distanced between each other 160 mm.<\/p>\n
        Duct support method:<\/strong><\/p>\n
        The duct is supported by an auxiliary structure made up of M16 threaded rods and 50 mm x 50 mm and 5 mm thick L-shaped upon which the duct rests. Maximum distance between the hangs will be 1200 mm.<\/p>\n
        Sealing of the penetration point through the support work. Sealing will be carried out with the following elements:<\/p>\n
          \n
        • Tecbor\u00ae boards 30 mm thick.<\/li>\n
        • Rock wool 50 mm thick and density 145 Kg\/m3.<\/li>\n<\/ul>\n
