MB-86 EI
The MB-86 EI system is used for the production of opening windows with EI 30 fire resistance, in accordance with EN 13501-2 + A1. The construction is based on the MB-86N system, which ensures high thermal and acoustic insulation, as well as excellent resistance to water penetration and air infiltration.

Advantages of the MB-86 EI system:
- three-chamber profile structure, where the central chamber serves as an insulating zone between thermal breaks with a width of 42 or 43 mm
- fire-resistant insulation elements located inside the internal chambers of the aluminium profiles, as well as dedicated accessories and materials operating in the space between the aluminium sections and the insulated glass unit
- a wide range of glazing thicknesses, allowing the use of various types of thermally insulated glass units, including double-chamber units
- hardware used in the MB-86 EI system meets the RC2 burglary-resistance class as standard, increasing the overall security of the construction
