Fireproof systems
PRODUCTS
A wide range of systems offered by Aluprof facilitate a variety of structural elements that are responsible for “fire protection zones” in buildings, and provide the right conditions for evacuation of its occupants. These solutions include both a window wall & door system option, extending to a typical “stick assembly” curtain wall system solution. The fire resistance performance of these solutions, depending on the project requirements, are available in a variety of classes, from as low as EI 15 (15 minutes) up to a an EI class of 120 (2 hours) for vertical assemblies, and achieve a class of REI 20/ RE 30 for roof glazing.

System MB-78
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 tests carried out at the Building Technology Institute in Warsaw proved that the products manufactured with this system had also a very good acoustic insulation (up to 40 dB).
The following solutions, categorised by their common fire retardant properties, are responsible for the safety of a building’s occupants during a fire: MB-78EI internal & external partition walls & doors (classes EI 15 to EI 90), MB-78EI DPA automatic sliding doors (EI 30), MB-118E fire walls (EI 120), MB-SR50 EI and MB-SR50N EI curtain wall (classes EI 15 to EI 60), MB-SR50 EI EFEKT and MB-SR50N EI EFEKT curtain walls (classes EI60), glazed fire roofs (RE 120/ RE 30), MB-45D smoke-tight door & smoke exhaust windows & valves.
An important feature of the Aluprof fire rated solutions is their ability to interface with each other, one system to the next, whilst maintaining the necessary fire resistance. This is demonstrated with the integration of the MB-78EI door into the MB-SR50 EI and MB-SR50N EI curtain wall, enabling the whole structure to achieve a common EI 30 or EI 60 class performance. The same MB-78EI door possibility exists, with implementation into the MB-118EI wall system.
