Our Picks
True Blackout vs Room-Darkening
Marketing labels are vague. The honest definitions:
- True blackout: 99-100% light block. Triple-weave fabric with foam or rubber backing. Rooms feel like 2 AM at noon.
- Room-darkening: 80-95% light block. Lighter weight fabric, no backing. Sleep but with morning light visible.
- Sheer/light-filtering: 50-70% light block. Decorative more than functional.
Eliminating Side Gaps
Even true blackout fabric fails if light pours around the sides or top. The fix: curtain rod that extends 8-12 inches past the window on each side, plus mounted ceiling-to-floor (or as close to ceiling as possible).
For total blackout: pair curtains with a roller blackout shade. The roller blocks the window plane; curtains absorb side bleed. Combined system gets to true 100%.
Insulation Bonus
Blackout curtains aren't just light-blocking. The triple-weave fabric also insulates. Cuts heat gain in summer 25-30% on west-facing windows. R-value bonus comes free.

Do blackout curtains really block 100%?
Triple-weave with backing: yes. Single-layer "blackout" curtains: 80-95%. Read the spec.
Why do I still see light at the edges?
Side gaps. Mount the rod 8-12" wider than the window on each side. Or pair with roller blackout shade for full coverage.
Will they reduce my AC bill?
Yes, blackout curtains reduce heat gain 25-30% on west-facing windows in California.
Curtain rod or curtain track?
Rod for most installs (cheaper, easier). Track for ceiling-to-floor or wraparound bay-window installs.
How much for install?
$99-$199/window including rod mounting and curtain hanging. Whole bedroom: $199-$399.
