Bow windows: following a curve with straight panels

A bow window is a gentle curve made of four, five or six narrow lights. It is one of the nicest features a house can have and one of the trickiest to dress, because every product on the market is made flat.

The trick is segmentation: enough narrow panels, angled to each other, that the eye reads a curve rather than a series of facets.

Shutters on a bow

Each light gets its own frame, and the frames are joined with angled posts calculated from the measured internal angle at every mullion. A five-light bow becomes five panel sets, and the run follows the curve.

Because the panels are narrow, we usually drop to a smaller louvre size so the proportions look right rather than stubby.

The blind alternatives

Where a shutter is not the right budget or look, two systems handle a curve.

  • Vertical blinds on a bendable curved track — a continuous sweep, still the most practical for a large bow
  • Individual roller blinds per light — clean and modest, but the mullion gaps are visible
  • Perfect-fit blinds — excellent on a UPVC bow, one per pane, no visible brackets

Coastal bows

Bow windows on seafront properties in Hythe, Sandgate and Folkestone take direct salt air and strong low sun off the water. We steer toward moisture-stable shutter ranges and UV-stable fabrics for those frontages rather than standard timber.

Window shapes - your questions

Normally one panel set per glazed light, so a five-light bow gets five. We confirm the exact layout at survey and show you the set-out before ordering.

Only with a vertical blind on a curved track — that is the one system that genuinely bends. Everything else has to be segmented.

Per square metre they are similar, but a bow has more frames, more posts and a longer survey, so the total is higher than a flat window of the same area. Your quote itemises it.

Yes, each panel is hinged and swings clear so you can reach the window to clean or open it. On very tight bows we can specify a tilt-only fixed panel instead.
