MB-79N SI Window 1-sash Fix with Vienna Muntins

The MB-79N is the latest product to join ALUPROF’s family of economic window and door systems. The successor to our highly popular MB-70 system, which has found wide use in the construction industry, it has been introduced with a view to meeting heightened thermal insulation requirements.
It is employed for a broad range of structures, including fixed, turn, tilt, and tilt-and-slide windows, exterior doors, both single and double, and shop window-type solutions with doors.

Three thermal construction variants:

• the MB-79N E; the most economic, central gasket for windows,
• the MB-79N ST; a two-component, central gasket for windows, designed to provide high thermal insulation,
• the MB-79N SI; providing the best thermal insulation. The profiles are fitted with insulating inserts produced using expanded polystyrene (EPS) and a two-component, central gasket.
