The Best Window Treatments for Blocking Light

Whether you are a light sleeper, a shift worker, or trying to eliminate glare in a media room, finding window treatments that truly block out the sun is a top priority. Many homeowners buy "blackout" curtains from a store only to find that light still bleeds through the fabric or around the edges. What are the best window treatments for achieving true darkness?

To effectively block light, you need the right materials and the right installation method. The best options include:

Option	Light Blocking Level	Best For
Blackout Roller Shades (outside mount w/ side channels)	Excellent	Bedrooms, media rooms
Blackout Cellular Shades	Excellent	Bedrooms; also provides insulation
Blackout-Lined Custom Drapery	Excellent	Primary bedrooms, formal rooms
Layered Blackout Shade + Lined Drapery	Maximum	Home theaters, nurseries, shift workers
Light-Filtering Shades	Moderate	Living rooms, kitchens

Designer Insight

True blackout is about more than just the fabric; it's about the fit," explains the Avabelle Interiors team. "When we design for a primary bedroom or a home theater, we meticulously measure to ensure the treatments overlap the window casing perfectly. We often recommend a layered approach—a motorized blackout shade for easy daily use, paired with stationary drapery panels to absorb any residual light bleed at the edges, creating a dark, restful sanctuary."
