Key Advantages

The system features a triple-glazed profile with the central section functioning as an insulation zone, set between thermal breaks measuring 43 or 42 mm. To provide fire insulation, specialized materials and custom-designed accessories are incorporated into the aluminum profiles, with additional components functioning in the space between the profiles and the glass.

One unique aspect is that EI2-rated doors do not require fire insulation materials within the aluminum profiles. This design simplifies the prefabrication process, reducing construction time and costs. However, inserts are necessary for frame and transom profiles to maintain fire resistance.

The MB-86 EI accommodates a wide range of glass thicknesses, allowing for the use of various glazing options, including double-glazing units. The standard hardware for MB-86 EI windows comes with an RC2 burglary resistance rating, offering both safety and security.

Technical Performance

• Air Infiltration: Class 4 (EN 12207) for both windows and doors
