The MB-78EI and MB-118EI fire rated walls are used to make fire partitions with fire resistance class of EI30 to EI120. The systems are classified as non-fire spreading (NRO). It’s design & construction is such that, it provides a technical connection with the MB-78EI door, which means a number of common components (such as glazing beads, cooling inserts, expanding tapes, seals and most accessories) and also similar to the basic system, production and installation technology.
The systems have been developed on the basis of 3 and 5 five chamber insulated aluminium profile. The inner chamber profiles, as well as insulating space between them, are filled with fire insulation elements. On the outer surfaces there are expanding tapes which are additionally mounted, and the whole structure is completed by steel accessories components, joining both sides of the profiles. |

MB-78EI system-based solution for transparent fire-resisting walls, the so-called “silicone joined glazed walls”. It enables the fabrication of internal partitions without the visible vertical profiles that separate the individual modules of the wall, whilst preserving the full fire resistance. The gap between the glass panes is only 4 mm and is filled with fire-stop intumescent material and non-flammable silicone. The silicone is available in three colours (black, grey, or white). That way, fire-resisting partitions can be up to 3.6 m high, with modules’ width of up to 1.8 m. Fire tests carried out at the Building Research Institute (ITB) included a “free edge” model, so there is no limit as to the maximum length of this type of wall.
MB-78EI brings virtually unlimited design and construction possibilities of very large internal partition walling. Thanks to the transparent modules, all the constructions fabricated using this system make the interiors optically bigger. The system also provides security by allowing the arrangement of the building’s fire zones and this ensuring appropriate conditions for the evacuation of building occupants. |
