MB-86N is a modernised version of the popular MB-86 aluminium window and door system. Static strength and thermal insulation of the construction have been improved.

The system is available in a standard version MB-86N ST and MB-86N SI, designed to maximise heat conservation.

The refreshed version of the windows includes new thermal separators allowing the use of a gasket in the thermal insulation area, and its improved kinematics make it possible to create larger windows.

Along with the new solutions come more customisation options for MB-86N. These include the possibility of using a double-sided handle on window sashes, choosing FIX glazing from the outside or selecting a Nail Fin frame for the US market.
