Independent tests have confirmed that products built in system have very good thermal insulation properties (Uf from 1.60 W/m2K) and acoustic properties (up to 40). The construction of the system is based on and insulated aluminium profile with a thickness of 78 mm. This effect is ensured by, among others, specially profiled 34 mm wide thermal joints with low thermal conductivity.

Allowable construction sizes include permanent partitions of up to 4 m and swing doors with a leaf of up to 1.4 m x 2.5 m. MB-78 EI doors can be installed individually or as part of a larger glazed construction, as well as in the anti-fire facades of compatible systems. Angle joints of the walls are also available in this system, and profiles can be bent or given arch shapes. Additional decorative bars can improve the appearance of the doors.

Also available in a wondow version.
