What Are Blackout Curtains?
Blackout curtains are designed with tightly woven, multi-layered fabrics—often with an additional lining—to block up to 100% of incoming light.
They’re ideal if you need complete darkness, whether for better sleep, nursery naps, or a home theater experience.
Key Benefits:
-
95%–100% light block for a pitch-dark room
-
Superior day and night privacy
-
Reduces heat transfer by up to 33% (U.S. Department of Energy data)
-
Great for bedrooms, nurseries, and media rooms
What Are Room Darkening Curtains?
Room darkening curtains block 75%–90% of light, making the room significantly dimmer without achieving total blackout.
These are perfect when you want privacy and glare reduction but don’t mind some natural light.
Best Uses:
-
Living rooms and offices where some light is welcome
-
Dining areas where ambiance matters
-
Great for layering with sheers for a stylish effect
What Are Sheer Curtains?
Sheer curtains allow natural daylight to filter in while softening harsh sunlight.
While they provide minimal privacy, they are essential for layering and adding depth to your décor.
Layering Tip:
Combine EZcurtain Privacy Sheers with blackout panels to enjoy natural light during the day and complete privacy at night.
Which Curtains Are Best for Each Room?
| Room | Best Choice | Why It Works |
|---|---|---|
| Bedroom | Blackout Curtains | Promotes better sleep & full privacy |
| Nursery | Double-Lined Blackout | Blocks 100% light for daytime naps |
| Living Room | Room Darkening + Sheers | Balance natural light & privacy |
| Home Office | Light Filtering | Reduces glare while keeping brightness |
| Home Theater | Blackout Curtains | Optimal for screen clarity |
Layering Techniques for Maximum Control
The most luxurious window treatments often involve layering:
-
Start with Privacy Sheers for soft daylight diffusion.
-
Add Blackout Panels on a double curtain rod for total control.
-
Pair with a decorative valance or side drapes for added texture.
This approach combines style + functionality, letting you adjust light, privacy, and energy efficiency throughout the day.
How to Measure for Perfect Curtains
