MB-78EI

Technical description:

MB-78EI fire resistant partition walls with doors in class range EI15 do EI90

The MB-78 EI system is designed for indoor or outdoor fire resistant partition walls with single or double leaf doors with fire resistance class EI 15, EI 30, EI 45, EI 60 or EI 90, according to PN-EN 13501-2: 2010. Numerous studies and calculations have also proved that the products made of this system have very good thermal insulation (Uf from 1.60 W / m2K) and acoustic values (up to 40 dB). Due to its properties, optimized technology and production costs, compatibility with other ALUPROF window and door systems and consistent technical development it is a very popular and widely used product in the construction market.

The design of the MB-78EI system is based on thermally insulated aluminum profiles with the depth of 78 mm. They are characterized by low value of heat transfer coefficient due to the application of, among others, special profiled thermal inserts with a width of 34 mm in their construction. The construction’s resistance to high temperature is provided by special GKF or CI fire insulation elements introduced into the inner chamber of the profiles and in the insulation spaces between the profiles and steel fittings and connectors.

The thickness of the fillings in the MB-78EI system is between 6mm and 49 mm. The fillings can be all typical fireproof glass panes, as well as layered non-transparent elements made of sheet metal and suitable plates to provide the required fire protection. Within this system you can also obtain smoke-tight structures.

The system also provides angular wall connectors, the possibility to bend profiles and obtain arch constructions, as well as the use of angled batten plates and ornamental mullions glued onto glass which are the characteristics that affect the shape and aesthetics of the entire building.

The range of permissible dimensions of the structure include fixed partition walls up to 4 m high and sliding doors with leaf dimensions up to 1.4 x 2.5 m. The MB-78EI door system can be installed individually, within larger glazed walls and fire resistant facades of MB-SR50EI and MB-SR50N EI systems. Wide construction possibilities, freedom of choice of various hinges, locks, automatic door locks and other fittings as well as optimized production technology are not the only advantages of this system. It also allows the application of automatic MB-78EI DPA fire resistant doors with fire resistance class EI15 or EI30, it is the basis for the construction of MB-78EI
all-glass walls with no mullions, MB-118EI walls which provide fire resistance in the EI120 class.

The MB-78EI system is subject to ATB Technical Approval No. AT-15-6006 / 2012 and the UK CERTIFIRE Certificate CF 5138.
