When it comes to window treatments, fabric choice matter more than just aesthetics. We also want to control light, privacy, and ambience in your space. Here’s a simple breakdown of the three main curtain fabric types, and where they work best:
Sheer: Soft Light, Gentle Privacy

Sheer fabrics filter natural light gently, creating a soft, airy atmosphere. They offer daytime privacy while still connecting your space to the outdoors — perfect for rooms where you want to maintain a light and open feel.
Best for:
- Living rooms
- Dining areas
- Layering under heavier curtains
Pros:
✓ Soft natural light
✓ Daytime privacy
✓ Elegant, relaxed look
Cons:
✕ Not ideal for nighttime privacy
✕ Doesn’t block heat or sunlight
Dimout: Balanced Light Control
Dimout fabrics offer more privacy and light reduction than sheers, but without going fully dark. They strike a balance, making them great for rooms that need flexibility across day and night.

Best for:
- Bedrooms
- Home offices
- TV/media rooms
Pros:
✓ Soft ambient light
✓ Moderate heat and glare reduction
✓ Greater privacy than sheers
Cons:
✕ Doesn’t fully darken a room
✕ Light that enters may take on the colour of the curtain fabric
Blackout: Total Darkness, Maximum Privacy

Blackout fabrics are designed to block nearly all outside light, providing full privacy and a restful environment — especially important for sleep and focus. High-quality blackout materials also help with insulation and noise reduction.
Best for:
- Bedrooms
- Nurseries
- Guest rooms
- Home cinemas
Pros:
✓ Complete light block
✓ Excellent privacy
✓ Energy-efficient
Cons:
✕ Can feel heavy or dark if not styled well
✕ Less natural light in daytime
Final Thoughts
Choosing the right fabric depends on how you use the space — and how you want it to feel. Many homes layer sheers and heavier curtains to enjoy the best of both worlds: soft light during the day, full privacy at night.
At Cava Curtains, we offer all three fabric types in a wide range of textures and colours — so whether you’re dressing a sunlit studio or a moody bedroom retreat, we’ll help you get the light just right.
