MB-78EI Fire-Rated Partitions with Fire-Rated Doors

Fire-Rated Partitions with EI15 to EI90 Doors

The MB-78EI fire-rated partition system is designed for creating internal or external fire-rated partitions with single or double-leaf doors, providing fire-resistance classes EI15, EI30, EI45, or EI60 in accordance with PN-EN 13501-2+A1:2016 standard. The system is based on thermally insulated aluminum profiles with a construction depth of 78 mm and utilizes special 34 mm wide thermal breaks that ensure a low overall heat transfer coefficient Uf. The system is compatible with Aluprof SA standard window/door systems MB-45, MB-60, and MB-70, utilizing common sections, components, and hardware. It provides the ability to use all types of fire-rated glass panels with fill thicknesses from 6 to 65 mm, and offers smoke-tight constructions in several execution variants. In 2011, the system was modernized, gaining new possibilities regarding permissible construction dimensions and other structural solutions.
