As part of our Custom Requests function, we offer Dutch In-swing windows in wood and wood clad. These windows are seldom seen in North America but we offer them because they fill a special niche as replacement units for traditional single/double-hung windows that have to be matched for exterior appearance, but where the clients does not want the vertical sliding operation. In a single-sash configuration, the Dutch In-swing window is very similar to a standard In-swing window that is either Tilt Only, Turn Only, or Tilt&Turn. The difference is that the Dutch window has a much wider depth and the sash is positioned on the inside face of the frame. Where the Dutch In-swing can simulate the look of a single/double-hung, is when the window has a top fixed sash that is positioned on the outside face of the frame...in this instance, the bottom operable sash can be Tilt Only, Turn Only, or Tilt&Turn which uses the bottom of the top sash as part of the "frame" that it closes against. As a result these Dutch units are more energy efficient but look almost identical to S/D-Hung units.
