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.
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 MB-SR50 EI mullion and transom wall system is designed for the construction of lightweight flat fire curtain walls of a hanging and filling type, with a fire resistance of EI15, EI30, EI45 and EI60 according to PN-EN 1364-3. The system is classified as non fire-spreading (NRO).
The system design is based on the supporting frame construction comprised of vertical (mullions) and horizontal (transoms) aluminium box sections with a characteristic width of 50 mm.To obtain the fire resistance of aluminium sections, mullions and transoms are fitted with special fire-proof inserts. The insert consists of an aluminium section with a relevant shape, which acts as a reinforcement, covered by fire-proof plates.
The construction designed in such a way enables the use of standard mullion and transom sections used in the MB-SR50 system, which to a large extent has improved the cost-effectiveness of the whole construction
