Aluprof offers the MB-78EI system-based transparent, fire-rated wall solution, the so-called muntin-free walls. This allows for the construction of internal partitions walls without the visible vertical wall profiles that separate the individual modules of the wall, while preserving their full fire resistance.
The joint between the glass panes is only 4 mm and is filled with fireproofing, intumescent material, and with non-inflammable silicone. The silicone is available in three colours (black, grey or white). The partition walls can thus have a height up to 3,6 m with modules’ width up to 1.8 m. Fire tests performed on these partition walls by the Poland’s Building Research Institute (ITB) included the so-called “free-edge model”, so there is no limit on the maximum length of this type of walls.
