What are S-Fold curtains, and how do they work?

Those soft, even waves you see in new homes are S-Fold curtains. Here's how they work and whether they suit your place.

The short answer

S-Fold curtains (also called wave curtains) hang from a special track with carriers spaced evenly along it, so the fabric falls into soft, even S-shaped folds. They look clean and modern, stack neatly to the side when open, and come in both sheer and room-darkening fabrics. Compared with pinch pleat curtains, they're simpler and more contemporary.

If you've walked through a new display home lately, you've seen S-Fold curtains: floor-to-ceiling fabric falling in soft, even waves. Here's how they work and where they make sense.

How they work

The secret is the track. S-Fold curtains run on a special track with carriers spaced evenly along it, joined so they stay at a set distance from each other. The curtain fabric attaches to those carriers, and because the spacing is always the same, the fabric falls into the same soft S-shaped wave all the way along.

That's why they look so tidy, open or closed. There are no bunched-up gathers or uneven pleats.

Sheer or room-darkening?

  • Sheers soften harsh light and glare, give daytime privacy and keep the view. Lovely in living rooms, especially in Townsville's bright afternoon light.
  • Room-darkening fabrics block much more light, and suit bedrooms and media rooms.
  • Both. Many people run a sheer and a room-darkening curtain on a double track, so they can choose by the time of day.

S-Fold vs other curtain styles

  • Pinch pleat: stitched pleats gathered at the top. More traditional and more formal.
  • Eyelet: rings punched into the fabric slide along a rod. Casual, and the folds are less even.
  • S-Fold: clean, modern and even. The most contemporary look of the three.

Where they work best

  • Living rooms and big windows, where they soften all that glass.
  • Sliding doors, because they stack neatly to one side.
  • Bedrooms, in room-darkening fabric or layered.
  • With shutters. S-Fold sheers alongside plantation shutters is a popular mix.

Common questions

Are S-Fold and wave curtains the same thing?

Yes, they're two names for the same style: curtains that hang from a special track and fall into even S-shaped folds.

Can S-Fold curtains block out light?

Yes. S-Fold curtains come in room-darkening fabrics as well as sheers. For a dark bedroom, you can layer a sheer and a room-darkening curtain, or pair a curtain with a blockout blind.

Do S-Fold curtains work on sliding doors?

Yes, they're a great choice for sliding doors and wide windows because they stack neatly to one side and are easy to open.
