One of the most important decisions when ordering custom blinds is choosing the right opacity level. The three main categories — sunscreen (light filtering), semi-blackout, and full blackout — serve very different purposes. Understanding the differences will help you make the right choice for each room.

Sunscreen / Light Filtering

Sunscreen fabrics are woven mesh materials with tiny openings that filter sunlight while maintaining your view of the outdoors. The openness factor (typically 1-5%) indicates how much light passes through. A 1% openness blocks more light and provides better daytime privacy, while 5% openness maintains a clearer view but less privacy.

Best for: Living rooms, kitchens, home offices, and any room where you want to reduce glare and UV damage while staying connected to the outdoors. Sunscreen roller shades are particularly popular for rooms with screens (TVs, computers) where glare reduction matters.

Privacy note: Sunscreen fabrics provide good daytime privacy (people outside cannot see in when it is brighter outside than inside). However, at night when interior lights are on, silhouettes may be visible from outside.

Semi-Blackout

Semi-blackout fabrics block most light while allowing a soft, diffused glow. They provide complete privacy at all times — day and night — without creating total darkness. The room remains bright enough to navigate without artificial lighting during the day.

Best for: Living rooms, dining rooms, guest bedrooms, and any space where you want privacy and light reduction without complete darkness. Semi-blackout is the most versatile option and works well in most rooms. Available in honeycomb, zebra, and roller shade collections.

Full Blackout

Full blackout fabrics block 99-100% of light using an opaque backing (often aluminium-coated). When properly installed with inside mount, the room becomes essentially dark even in direct sunlight. This is achieved through the fabric construction — no light passes through the material itself.

Best for: Master bedrooms, nurseries, home theatres, shift workers who sleep during the day, and anyone who needs complete darkness for quality sleep. Full blackout honeycomb blinds add insulation benefits on top of light blocking.

Important note: Even with blackout fabric, some light may enter around the edges of inside-mounted blinds. For absolute darkness, consider outside mount with overlap, or add side channels.

Can You Mix Opacity Levels?

Absolutely. Most homeowners use different opacity levels in different rooms based on function. A common combination: blackout in bedrooms, semi-blackout in living areas, and sunscreen in kitchens and offices. You can even install dual systems (sunscreen + blackout on the same window) for maximum flexibility.
