Window coverings seem simple until you realise how much they change a room. The right fabric shifts glare, temperature, privacy and mood in one move. At Circle Curtains, we’re asked the same question every week: sunscreen, light filtering or blockout fabric, what’s right for my space? Here’s a clear guide you can trust.
The quick summary: what each blind does
Sunscreen: lets daylight in, preserves your view and reduces glare and UV. Great for daytime living areas where you want a connection to the outside and heat reduction without losing the view.
Light filtering: diffuses light to create a soft, even glow indoors. It keeps privacy during the day while offering a warmer, cozier ambience which is popular for dining rooms, studies and bathrooms.
Blockout: stops nearly all daylight and provides full privacy. Use it in bedrooms, media rooms, or anywhere you need darkness like home cinemas or rooms that face the morning sun.
If you remember nothing else:
sunscreen = view + glare control
light filtering = soft light + privacy
blockout = darkness + privacy
How each option actually behaves
Openness & view-through
Sunscreen fabrics are rated by openness (1%, 3%, 5%). Lower numbers mean tighter weave and stronger glare control, but less view. Light-filtering fabrics don’t use openness ratings, they diffuse light so you can’t see outside clearly, but rooms feel bright and calm. Blockout is effectively 0% which means no light through the fabric.
UV, heat and comfort
Sunscreen cuts UV and reduces heat gain, especially handy on west-facing glass. Light filtering helps with glare and protects furnishings better than bare windows, but won’t cool a room like sunscreen. Blockout with thermal backing is best for insulation: cooler in summer, warmer in winter.
Where to use each type — practical room-by-room advice
Living rooms & kitchens
If you’ve got a view and want daylight without the squint, sunscreen is the daytime choice. For cozy, glare-free light and a bit more privacy, light filtering creates that soft, welcoming feel. Many homes pair sunscreen by day with curtains or a second roller for nights.
Bedrooms
We recommend blockout fabric, especially for early sunrise, street lighting. If you still want gentle daytime light, layer a sheer or translucent fabric and drop the blockout only when you need it.
Home office
Go with sunscreen with 1–3% openness to keep the view and tame reflections if you stare at the screen for long time. If your office doubles as a guest room, add a blockout curtain or dual roller to switch gears.
Bathrooms & hallways
Bathrooms (non-shower windows) and hallways benefit from light-filtering fabrics that provide daytime privacy and a soft, flattering light with minimal maintenance.
Layering: the fastest way to get the best of every world
You don’t have to pick one fabric and be stuck. Layering is the most flexible approach: mount a sunscreen for daytime heat and glare control, add a blockout behind it for nighttime privacy, or combine a light-filtering roller with side-drapes. Layering improves thermal insulation, gives more control over light, and helps achieve the exact look you want without compromising function.
How to choose: a short checklist to make the right decision
What matters most? View, privacy or darkness? If view and glare control: sunscreen. If soft daylight and privacy: light filtering. If darkness and privacy: blockout.
Which room and what time of day is the room used most? Choose based on peak usage (morning sun, evening TV, daytime work).
Do you need thermal help? For heat-prone rooms, sunscreen + reflective backing or blockout with thermal lining is better.
Do you want one solution or layering? Layering gives flexibility. Consider dual roller systems for convenience.
Budget and upgrade path: Sunscreen and light-filtering tend to be cost-effective; blockout and thermal-backed fabrics cost more but provide functional benefits. Plan upgrades room by room.
Final thoughts: pick the fabric that fits your life, not the trend
Choosing blinds shouldn’t be about following a modern trend, it’s about matching how you live. If you entertain in your living room and value a view, a low-openness sunscreen with an occasional blockout layer is a smart, long-term choice. If you work shifts or love to sleep in, invest in quality blockout. And if you love soft, warm daylight for reading and dining, light-filtering fabrics will create that calm glow you’ll enjoy every day.
