The MB-60E EI system is designed for creating fire-resistant single and double-leaf internal doors, as well as technical windows and fire-resistant partitions. These constructions comply with EI15 or EI30 classifications in accordance with the PN-EN 13501-2+A1:2010 standard and achieve self-locking performance rated as class C5 under EN 1191:2013-06. The system is certified as non-fire spreading (NRO).

This innovative solution utilizes aluminum profiles with a thermal break (MB-60E system), featuring a structural depth of 60 mm. The system’s fire resistance is achieved through specialized fire insulation materials placed inside the profile chambers. Additionally, intumescent tapes are incorporated to prevent the spread of fire by expanding under high temperatures to seal gaps effectively.

The system supports the use of standard fire-resistant glass classified as EI15 or EI30, with thicknesses ranging from 5 to 41 mm. The glass is secured on the interior side using glazing strips, while specialized steel reinforcements play a crucial role in keeping the glass intact and preventing it from falling out during a fire.

The MB-60E EI system enables the construction of doors with maximum leaf dimensions of 1.4 meters in width and 2.475 meters in height. For double-leaf doors, the total width can extend up to 2.58 meters. Its compatibility with other MB systems and its versatile design capabilities make this solution a top choice within its category, offering superior fire protection and outstanding functionality.
