French Window- GU brand
In this French window, two sashes are positioned side by side, and when opened, no mullion (vertical frame) is visible in the middle of the window. This creates a more complete and aesthetically pleasing view. It should be noted that in this type of French window, the main sash opens as a double-leaf (casement) and the secondary sash opens as a single-action (casement).
