  • A wide range of window functions for the users to choose from.
  • Profiles can be bent to fabricate arched windows.
  • Various finish versions possible with concealed sash windows, plus the Industrial “steel-look” version and three types of glazing beads: Standard, Prestige and Style.
  • Doors available with 1 or 2 sashes, outswing or inswing, and also with a soft-close function.
  • Designs adapted for various types of fixtures, including concealed window hinges or roller hinges in doors.

An advantage of MB-70 is an extremely low heat transfer coefficient, or the U-value — a feature provided by dedicated thermal breaks and weatherstrips. The advantage is very important in our times of growing demands for environmental protection and energy conservation.
