MB-86N is a window and door system with excellent parameters, capable of meeting the diverse requirements of users. The profile structure is available in two variants, depending on the needs for thermal energy saving: ST and SI. The system is distinguished by its excellent thermal and airtightness properties.

The strengths of the MB-86N system also include the high strength of the profiles, which makes it possible to create structures of large size and weight. There are versions of windows with a concealed sash MB-86US, as well as an outward opening window system with a thermal barrier MB-86 Casement. MB-86B was developed to meet the requirements of the Belgian market.
