MB-118EI Fireproof wall partitions of EI120

The system of fireproof walls MB-118EI is intended for execution of internal or external fireproof partitions of the fire resistance class EI120. The system has been classified as non-fire propagating. It is based on the system of fireproof partitions with the door MB-78EI, which provides most components, e.g. glazing beads, cooling inserts, expanding tapes, gaskets and most accessories. The MB-118EI system has been developed on the basis of a five chamber insulated aluminium profile, with a front to back depth of 118 mm. 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. The MB-118EI system can accommodate glazing units, panels or other similar glazing substrates of a thickness 31-35 mm or 48- 84mm. Thanks to its symmetrical composition, the structures that are made of it remain fire resistant in EI 120 class, both exposed to fire from the outside and the inside. An important feature affecting the functionality of the division of these partitions is the possibility to install the MB-78EI doors.
