MB-79N
MB-79N is a three-chamber window system with thermal insulation, designed for windows with high thermal parameters, very good durability and tightness.
An economical, functional system that meets all technical requirements.
There are three thermal versions: MB-79N E, MB-79N ST and MB-79N SI.
Based on the MB-79N system, it is possible to manufacture windows with a hidden sash MB-79N US and outward-tilting windows MB79N Casement.
