✅ During the Day:
When it’s brighter outside than inside, sheer or voile fabrics act like a soft screen. You can see out clearly, but people outside just see a blurred outline.
✘ At Night:
As soon as the light inside becomes brighter than outside — especially when lights go on — the effect reverses. People can now see in, because the fabric becomes translucent.
That’s why layering is essential for complete night-time privacy.

🪟 Blinds That Offer Daytime Privacy
(and Look Great Too)
There’s a wide range of blinds that provide partial or adjustable one-way privacy during the day.
Here’s a breakdown of the most effective:
🔹 Voile Roller Blinds – Clean, modern, and perfect for soft light during the day. To protect privacy in the evening, layer with a Roman blind or blackout roller.
🔹 Voile Roman Blinds – Elegant and soft-textured, Roman-style voiles offer daytime discretion with a more decorative feel.
🔹 Voile Vertical Blinds – By adjusting the louvres, you can control how much light comes in — but they may still become see-through at night. Commonly used on bifold doors.
🔹 Illusion Blinds – A cross between a sheer curtain and a vertical blind, these use voile strips suspended between louvres to provide a soft, stylish look and excellent light control.
🔹 Voile Curtains – Perfect for living areas and dining rooms. Use them on their own for light filtering during the day, or layer with lined curtains for evening privacy.

🌓 Duo, Vision & Zebra Roller Blinds
Adjustable Day & Night Control
These blinds go by several names — Duo Blinds, Vision Blinds, Zebra Blinds, or Day & Night Blinds — but all work on the same principle:
• Alternating bands of sheer and opaque fabric
• Slide past each other to allow light or provide privacy
• Easy to adjust for changing light throughout the day
They’re a fantastic choice if you want greater flexibility and are ideal for bifold doors, kitchens, or open-plan living areas.
🌗 Night and Day Pleated Blinds
Pleated blinds also come in sheer fabrics and can be fitted in standard or Perfect Fit systems. You can even go one step further:
🔸 Night & Day Pleated Blinds
These feature two pleated fabrics in one blind:
• A voile for soft light
• A blackout or dim-out for evening privacy
Available in standard and Perfect Fit versions — especially useful in conservatories or bifold doors.
Other Blinds That Offer Privacy Day and Night
Shutters: With adjustable louvres, you can tilt them to let in light and maintain privacy — and they’re incredibly stylish too.
Venetian Blinds: Similar to shutters, their moveable slats can be angled for light control and privacy.

Can people see through one-way blinds at night?
Yes — once the inside is brighter, sheer fabrics become see-through. That’s why we recommend layering or switching to dual-function blinds.
Are duo, vision, and zebra blinds the same thing?
Yes — they’re just different names for blinds with alternating sheer and opaque stripes, giving you adjustable control over light and privacy.
What’s the best blind for bifold doors with privacy control?
Vertical blinds, duo blinds, and Perfect Fit Pleated Night & Day blinds all work well, depending on the look and functionality you want.
Can I get a sheer blind with blackout built in?
Yes — our Pleated Night & Day Blinds have two layers of fabric, letting you switch between voile and blackout in one neat design.
What should I choose for front vs rear windows?
- Front-facing? Go for layered blinds or duo options for complete evening privacy
- Back-facing? Voile or verticals may offer enough coverage, especially in gardens
