Window Treatments

Blackout Liner

Blackout liners are specialized light-blocking layers that transform any curtain or shade into a room-darkening treatment. Made from tightly woven or coated fabric that prevents light transmission, blackout liners are essential for bedrooms, nurseries, media rooms, and shift workers needing daytime darkness. The liner can be sewn into curtain construction or installed separately on a track behind decorative curtains. Separate installation allows removing the blackout function seasonally or when total darkness is not needed.

Placement & Usage Tips

For complete blackout, liners must extend beyond window edges and prevent light gaps. Consider ceiling-mounted tracks for continuous coverage. Wrap returns around to walls for edge blocking.

💡 Pro Tip

Even with blackout liners, light sneaks through gaps at edges and top. For nurseries and critical applications, combine blackout curtains with blackout roller shades for layered protection.
