System Description

The NORDWIN aluminium system can be installed without alteration of the wood cross

  • Additional time-consuming and expensive processing of glazing strips is omitted
    because the aluminium sash profile replaces the glazing strip.
  • Aluminium frames are installed bay by bay in a multipart window, which permits rational
    assembly of the aluminium windows.
  • Mullions, transoms, fixed glazing, double rebate and element linkage can be carried out
  • With small radii on the visible edge, the profiles display clear lines.
  • GUTMANN NORDWIN can be processed with the accessory range from the GUTMANN
    MIRA system without restriction.
