Do you have honeycomb shades that run in a track up and down on the sides?
Cellular shades with side tracks—also known as side channel shades or cellular blinds with side rails—are designed to significantly reduce light gaps and improve privacy. By adding vertical side channels along the edges of the window, these shades create a tighter seal compared to standard cellular shades.
This makes them a popular solution for bedrooms, media rooms, and any space where better light control and insulation are important.

What Are Side Tracks on Cellular Shades?
Side tracks are narrow channels installed along both sides of the window frame. When the shade is lowered, the edges of the fabric sit inside these channels, helping to block light from leaking in around the sides.
Unlike standard shades, which leave small gaps between the fabric and window frame, cellular window shades with side tracks create a more enclosed fit for improved performance.
Benefits of Cellular Shades With Side Tracks
- Reduced light gaps: Helps block unwanted light along the edges of the window
- Improved blackout performance: Ideal for bedrooms and home theaters
- Better privacy: Limits visibility from outside
- Enhanced insulation: Reduces air leakage and improves energy efficiency
- Cleaner appearance: Creates a more fitted, custom look
Are Cellular Shades With Side Tracks Truly Blackout?
Blackout cellular shades with side tracks provide one of the best solutions for minimizing light in a room. While no window treatment can guarantee 100% total darkness in all conditions, adding side channels dramatically reduces the light gaps that are common with standard shades.
For most applications, this combination offers near-blackout performance and is ideal for sleeping areas or rooms where light control is critical. Blackout side tracks help reduce light gaps along the edges of honeycomb shades, making them ideal for bedrooms and media rooms.
Common Uses for Side Track Shades
- Bedrooms: Improve sleep by reducing early morning light
- Media rooms: Enhance screen visibility by minimizing glare
- Home offices: Reduce distractions from outside light
- RVs and motorhomes: Improve insulation and privacy in compact spaces
- Street-facing windows: Increase privacy and light control
Side Tracks vs Standard Cellular Shades
Standard cellular shades provide excellent insulation, but they leave small gaps along the sides of the window. These gaps can allow light to enter and reduce overall privacy.
By comparison, cellular shades with side channels are designed to minimize these gaps, offering better performance in both light control and insulation.
- Standard shades: Small light gaps on the sides
- Shades with side tracks: Reduced light gaps and improved privacy
Are Side Tracks Available on All Cellular Shades?
Side track systems are typically offered as an upgrade option on select cellular shade products. Availability can vary depending on the specific product, size, and mounting requirements.
To see if this feature is available, look for upgrade options when customizing your shade or explore products that offer enhanced privacy and light control features.
