About the system
MB-86N is a window and door system offered in ST and SI versions with different thermal performance. Wide thermal breaks make room for an extra barrier in the insulation zone, and a two-component central gasket seals the gap between sash and frame.
It covers tilt-and-turn, side-hung and hopper windows as well as inward- and outward-opening doors, with burglar-resistant versions up to class RC4.
