Flag Windows

Within the overarching theme of joined windows, you will find numerous different window designs including flag windows. This design consists of three windows with one wide frame fixed in between two slimmer frames. Windows featured in a flag will usually include sliding sash windows carrying all the heritage elements found on traditional timber frames including Georgian bars and run-through sash horns to maintain the association with historic windows.

Types of Flag Windows

Material

Flag windows are available in the sliding sash window style. With our 15+ years’ experience, we’re experts in making windows in PVCu. PVCu is great for heritage applications where bay or other coupled windows may be required; it is easy to maintain and can quite easily be welded and joined. PVC is durable and is a very popular choice for medium and long-term applications because of its long lifespan and resistance to weathering.

Design

Flag windows are also known as triple windows because the unit consist of 3 separate frames coupled together into one. Generally, flag windows or triple windows will feature a middle section that is around twice the width of the frames sitting beside it. The configuration of sliding sash windows can’t be modified, and multiple frames coupled together e.g. flag windows or double windows is often required for wide openings.

Side by Side Windows

Windows are joined using something called a coupler. These are available in different sizes depending on your requirements. The coupler we use to join the sash windows together is one that has been designed for frame to frame coupling with reduced sightlines. With Quickslide’s slim coupler you can couple windows that feature the slimmest horizontal frame sections possible giving you a window solution that isn’t completely obstructed by frame sections. Generally, any double or triple windows will be joined in our factory and no additional assembly will be required.

Doors with Side Windows

To cope with apertures that are oversize, it is common practice to use side or top panels to make up the difference in height or width. Same height fixed glass panels are also known as side lights. For added natural light, you can even couple a window on either side of your door as illustrated. Doors coupled with windows can be scaled to fit your aperture.
