MB-60E EI is an economical system for creating internal fire partitions and doors with a fire resistance class up to EI30, with the possibility of meeting smoke-tightness (Sa, S200) and self-closing (C5) requirements. The construction, based on aluminum profiles with additional insulation elements, combines lightness and aesthetics with the required fire protection. The system allows for the design of large glazed walls, including mullion-free versions with a narrow 3–5 mm joint, as well as single- and double-leaf doors with leaf dimensions up to 1400 x 2475 mm. It can be used on escape routes, in aeration zones, or in facilities requiring additional burglary protection. Thanks to compatibility with other Aluprof systems, easy fabrication, and a favorable quality-to-price ratio, MB-60E EI constitutes an attractive solution wherever fire safety, aesthetics, and an optimal investment budget matter.
