The MB-78EI fire partition system is intended for producing internal or external fire partition walls with single- or double-leaf doors with a fire resistance class of EI 15, EI 30, EI 45 or EI 60, according to the PN-EN 13501-2+A1:2010 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 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 Uf, which results, in part, thanks to the use of special profiled thermal breaks of the width of 34 mm. The system enables the application of all types of fire-resistant glass panels of appropriate class (infill thickness from 6 to 49.5 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). In 2011, the MB-78EI system was modernized and gained new possibilities with regard to admissible structure dimensions and other construction solutions. The MB-78 EI system achieved the Technical Approvals ITB no. AT-15-6006/2006 and AT-15-6006/2011.
