When people shop for S-Fold or Wave Fold curtains, the focus is usually on fabric. But the way curtains hang, move, and form waves depends mainly on the track system behind them.
There are three common systems:
- Standard curtain tracks
- S-Fold tracks
- Wave Fold tracks
Each system controls curtain movement differently, which affects the final appearance.
1. The three curtain track systems
Standard curtain tracks
Standard tracks are widely used in Australian homes and are designed for traditional curtain styles.
They work well with:
- Pinch pleat curtains
- Pencil pleat curtains
- Pull pleated curtains
- Hook top curtains (with 4-prong hooks)
These systems are designed for classic curtain headings rather than wave-style curtains.
- Gliders are not linked
- Spacing is flexible and manual
- Best suited for traditional curtain styles
- Not designed for wave formation
S-Fold curtain tracks (key-shaped carrier system + button snap system)
S-Fold systems use key-shaped carriers that are linked by cord.
Curtains attach using a button snap system that connects into these carriers.
A key detail is compatibility between the curtain and the track system. S-Fold curtains usually have a back tape with integrated buttons, which must match the key-shaped carrier openings.
It is important to check:
- Button diameter on the curtain
- Inner diameter of the key-shaped carrier
Because different suppliers use slightly different systems, S-Fold components are not always universally compatible.
When matched correctly, the result is a structured and consistent S-shaped wave with controlled spacing.
Wave Fold curtain tracks (O-shaped carrier system)
Wave Fold systems use O-shaped carriers linked by cord.
Curtains attach using small hooks (snail hooks), which connect into the carrier system.
- Smoother wave movement
- Flexible spacing
- Adjustable wave depth
- Softer modern appearance
From soft, refined waves to deeper, more dramatic waves, all styles maintain a structured and consistent appearance.
2. What most customers choose
Wave Fold systems are becoming one of the most popular choices for modern homes and new curtain installations.
One reason is flexibility. The wave spacing can be adjusted more easily, and the overall depth of the fold can be fine-tuned depending on the look you want — from soft, refined waves to deeper, more dramatic waves, all styles maintain a structured and consistent appearance.
In the market, Wave Fold systems are also sometimes referred to as “S-Fold” by different suppliers, even though the hardware and attachment methods can vary slightly. In this guide, we refer to it as Wave Fold to stay consistent with our products.
3. Why wave curtains sometimes don’t look right
- Gliders are not linked
- Spacing is not evenly controlled
- Wave rhythm becomes inconsistent
This is why wave curtains can look different even when using the same fabric.
4. If you already have a standard track
S-Wave butterfly hooks
These hooks help improve wave formation by improving spacing consistency on standard tracks and upgrading existing curtain systems.
- Improved wave definition compared to standard hooks
- Better fold consistency
- Noticeable visual upgrade
Limitations:
- Wave depth is not perfectly symmetrical
- Front wave is usually deeper than back return
- Not as precise as a full wave track system
5. Best option for new installations

6. Simple decision guide
Keep your current track if:
- It runs smoothly
- You are using traditional curtain styles
- You are not aiming for wave styling
Use S-Wave butterfly hooks if:
- You want a wave look without replacing your track
- You are upgrading existing curtains
Choose a Wave Fold track system if:
- You want a relaxed, modern and premium finish
- You are installing new curtains
- You want the most consistent wave result
Watch how it works
Final takeaway
Standard tracks are designed for traditional curtain styles such as pinch pleat, pencil pleat, and hook top curtains.
S-Fold systems require correct matching between curtain buttons and key-shaped carriers, and compatibility is not always universal across suppliers.
Wave systems are designed specifically for modern wave curtains, offering flexible spacing, adjustable wave depth, and a relaxed but structured finish.
Depending on your situation:
- S-Wave butterfly hooks improve existing standard tracks
- Extendable Wave Fold systems deliver the most consistent result for new installations
