It is used to make internal fire doors single
and double-sash fire doors. The system also makes it possible to the
construction of so-called technical windows and fire protection partitions.
Constructions made on the basis of the MB-60E EI system are characterised by the fire resistance class EI15 or EI30 according to PN-EN 13501-2+A1, the doors can additionally meet the requirements of smoke tightness in the S200, Sa class according to PN-EN 13501-2+A1 and self-locking in the C5 class according to PN-EN 1191:2013-06. The system is classified as non fire-spreading (NRO).
The system allows for the use of all typical fireproof glass of EI15 and EI30 classes with a thickness of 5 to 41mm. In MB-60E EI, the glass is fixed with glazing beads on the internal side. Special steel accessories are used to prevent the glass from falling out during a fire.
The structural depth of the sections is 60mm. The fire resistance of the structure is ensured by fire insulation elements which are installed in the internal chambers of the sections. The structures are additionally equipped with intumescent strips, which are an impenetrable barrier to fire.
System MB-78 EI
The MB-78EI system is used to make internal or external fire partitions with single and double-leaf doors of fire resistance class EI 15, EI 30, EI 45, EI 60 or EI 90, according to the PN-EN 13501-2:2016 standard. Numerous tests and calculations have also proven that products made of this system have very good thermal insulation (Uf from 1.60 W/(m2K)) and acoustic insulation (up to 40 dB) for single pane EI30. The doors can additionally meet the requirements of smoke tightness in class S200, Sa according to PN-EN 13501-2+A1, and self-locking in class C5 according to PN-EN 1191:2013-06.
The MB-78EI system construction is based on thermally insulated aluminium profiles with a depth of 78 mm. They are characterised by a low heat transfer coefficient due to the use of, among other things, special profiled thermal breaks 34 mm wide in their construction. The structure's resistance to high temperatures is ensured by special GKF or CI fire insulation elements inserted into the chambers inside the profiles and in the insulation spaces between the profiles, as well as steel accessories and connectors.
The thickness of fillings in the MB-78EI system ranges from 6 to 65 mm. The fillings may be all typical fireproof panes, as well as as well as opaque layered elements composed of sheet metal and appropriate panels providing the required fire protection. Smoke-proof structures can also be achieved with this system.
The MB-78EI system is covered by numerous approval documents in the European and Middle Eastern markets.
System MB-86 EI
Profiles with a three-chamber structure, where the central part is the insulation chamber between the thermal breaks with a width of 43 or 42 mm.
Fire insulation components in the internal chambers of aluminium sections and special accessories and materials operating in the space between the aluminium sections and the glass.
In EI2 class doors, no fire insulation elements are required in the internal chambers of the sections aluminium sections, which results in faster prefabrication and lower price of the structure. construction. In shopfronts, inserts are required in door frame profiles and crossbars.
The wide range of glass thicknesses that can be used makes it possible to use different types of insulating glass, including double-glazed units.
The fittings used in the MB-86 EI windows are, as standard, in the RC2 anti-burglary class.
System MB-119 EI
The MB-118EI fire wall system is used to make for making internal and external fire partitions of fire resistance class EI120. The system is classified as non fire-spreading (NRO).
The construction is technically related to the fire wall system with MB-78EI doors, which means many common components (including glazing beads, cooling inserts, intumescent strips, gaskets and most accessories), as well as production and assembly technology analogous to the base system.
The MB-118EI system is based on thermally insulated five-chamber aluminium profiles with a construction depth of 118 mm. Fire insulation elements are inserted in the internal chambers of the profiles as well as in the insulation spaces between the profiles. Intumescent strips are additionally installed on the external surfaces, and the entire structure is completed with steel accessories connecting both parts of the profiles.
The fillings in the MB-118EI system partitions can be between 48 and 84 mm thick.
Through to its symmetrical structure, structures made of it maintain fire resistance in the EI120 class, both in the situation ofthe impact of fire from the outside and inside. An important feature, affecting the functionality of these fire partitions, is the possibility of mounting MB-78EI doors in them.
