    The MB-78EI fire partition system is characterized by both the tightness and the fire insulation properties. It meets the constantly toughening requirements of Polish and European standards as regards the constructions surrounding the zone of a safe evacuation for people and property in a burning building. It is intended for producing internal or external fire partition walls with single- or double-leaf doors featured by a fire resistance class of EI15, EI30, EI45 or EI60, according to the PN-B-02851-1:1997 and PN-EN 13501-2:2005 norm. To a great extent, it is compatible with the standard window/door systems of ALUPROF S.A.: MB-45, MB-60 and MB-70 (they have common sections, details, hardware, treatment processes, etc).

    The structure of the MB-78 EI system is based on the thermally-insulated aluminium profiles. The construction depth of the sections is equal to 78 mm. The profiles are characterized by a low overall heat transfer coefficient U, thanks to application of, among others, special profiled thermal breaks of the width of 34 mm. The system enables glazing with all types of fire-resistant glass panels of appropriate class (infill thickness from 8 to 49 mm). With this system, the smoke-proof structures in several production versions are also available. The tests carried out at the Building Technology Institute in Warsaw proved that the products manufactured with this system had also a very good acoustic insulation (up to 40 dB).
