Choose blackout shades when darkness and reliable privacy matter most. Choose solar shades when you want to cut glare and strong sunlight while keeping natural light and the outside view. If you need both, a layered setup can give you daytime sun control and nighttime privacy.
Key Takeaways
- Blackout shades are usually the better choice for bedrooms, nurseries, media rooms, and other spaces where darkness or nighttime privacy matters most.
- Solar shades are usually better for living rooms, home offices, large windows, and sliding glass doors where you want glare control without losing the view.
- Solar shades can provide useful daytime privacy, but they aren’t reliable for nighttime privacy when interior lights are on.
- Blackout fabric can block light through the material, but light may still leak around the edges depending on how the shade is mounted.
- With solar shades, a lower openness percentage means stronger sun and glare control; a higher percentage means more daylight and a clearer outside view.
- If one room needs both filtered daylight during the day and full privacy or darkness at night, consider layering solar and blackout treatments.
Blackout Shades vs. Solar Shades: The Quick Difference
The simplest way to think about the difference is this: blackout shades block light, while solar shades filter it. Neither is automatically better. The right choice depends on what you need the window covering to do.
| Priority | Blackout Shades | Solar Shades |
| Maximum darkness | Best choice | Not designed for blackout |
| Daytime privacy | Yes | Usually good |
| Nighttime privacy | Yes | Limited when lights are on |
| Outside view | Blocked when closed | Preserved |
| Glare reduction | Excellent | Excellent |
| Natural daylight | Blocked | Filtered |
| UV protection | Excellent | Excellent |
| Best fit | Bedrooms, nurseries, media rooms | Living rooms, offices, large windows |
Choose Blackout Shades When Darkness Matters Most
Blackout shades are designed for rooms where light control is the priority. When lowered, the fabric itself prevents visible light from passing through, making them a strong fit for spaces used for sleeping, naps, or watching a screen without reflections.
They’re especially useful for primary and guest bedrooms, nurseries and children’s rooms, shift workers or anyone who sleeps during the day, media rooms and home theaters, and rooms where dependable nighttime privacy is important. Best rule of thumb: if you’d be unhappy seeing daylight through the window covering, start with blackout rather than solar.
Are blackout shades really 100% blackout? The fabric can be fully opaque, but the finished window may not be completely dark. Light can still enter around the sides, top, or bottom of a roller shade, especially with an inside mount. If you need the room as dark as possible, an outside mount that overlaps the window opening can reduce edge light, and side channels, a cassette, or blackout-lined drapery can also help where maximum darkness is important. We cover motorized and roller-specific options in more depth in our guide to roller and solar shades.
Choose Solar Shades When You Want Sun Control Without Losing the View
Solar shades are made to soften strong sunlight rather than eliminate it. They reduce glare, filter UV exposure, and can make sunny rooms more comfortable while still allowing daylight and an outside view, which makes them a practical choice for living and family rooms, home offices with screen glare, sunrooms, large picture windows, sliding glass doors, and south- or west-facing rooms that receive strong sun.
For a living area with a great view, this is the main advantage: you can lower the shade during bright parts of the day without turning the window into an opaque wall.
The Biggest Privacy Difference to Know
Privacy is one of the most important differences between these two options. When closed, blackout shades create a solid visual barrier, making them the safer choice when you need dependable privacy both during the day and at night.
Solar shades can provide useful privacy during daylight because it’s brighter outside than inside. After dark, that advantage can reverse. If the interior lights are on, people outside may be able to see through the shade. Important: don’t rely on a solar shade alone for nighttime privacy in a bedroom, bathroom, or ground-floor room where privacy is essential.
What Solar Shade Openness Percentage Should You Choose?
The openness factor tells you how open the solar fabric is. You don’t need the technical details to use it: lower numbers give you stronger sun control, and higher numbers give you a clearer view.
| Openness | Best For | Main Trade-Off |
| 1% | Very strong sun, heavy glare, maximum UV control | Least outside visibility |
| 3% | West-facing windows, bright offices, strong glare | Balanced view and control |
| 5% | Living rooms and general daytime spaces | More daylight and view |
| 10% | Shaded or north-facing windows where view matters most | Less glare and sun control |
For many general living spaces, 5% is a common middle ground. If the window takes hard afternoon sun or creates screen glare, 1% to 3% may make more sense.
Which One Is Better for Heat and Strong Sun?
Both can help reduce the impact of direct sun, but they fit different priorities. Solar shades are useful when you want to control glare and solar exposure while continuing to use natural daylight. blackout shades are useful when you’re comfortable blocking the light and view completely.
West-facing windows deserve extra attention because late-afternoon sun can be especially intense. In a living room or office, a tighter solar shade can reduce harsh glare without closing off the room. In a bedroom or media room, blackout may be the better fit because darkness matters more than preserving the view. Neither standard roller option should be treated as a high-performance insulation system. Their main benefit is managing sunlight at the window rather than adding major insulation value.
Which One Helps Protect Furniture and Flooring?
Sunlight can contribute to fading and discoloration in hardwood floors, rugs, upholstery, artwork, and other furnishings. Both blackout and solar shades reduce exposure when they’re lowered.
Solar shades have a useful advantage in daytime living spaces: they can block a large share of UV exposure while still letting you keep natural light and an outside view. The relationship is fairly direct: a 1% openness fabric blocks roughly 99% of UV rays, while a 10% openness fabric blocks roughly 90%, so common solar fabrics generally block somewhere between 90% and 99% of UV depending on the openness level you choose.
What About Large Windows and Sliding Glass Doors?
Solar shades are often a natural fit for large areas of glass because they control glare and sun without making the room feel closed off. They can work well on patio doors, picture windows, and walls of glass where preserving the outdoor connection matters.
Very wide openings may need more than one shade instead of a single oversized roller. Custom sizing or professional installation can be worthwhile when you’re covering large sliders, tall windows, or several adjacent windows.
Sometimes the Best Answer Is Both
Some rooms need two different things at different times of day. A bedroom may get harsh afternoon sun but still need complete privacy and darkness at night. A ground-floor living room may benefit from daytime glare control but need a solid privacy layer after dark.
A layered setup solves that problem: use a solar shade during the day to reduce glare, UV exposure, and strong sunlight while preserving the view, and close blackout drapery or a second blackout shade at night for privacy and darkness. Dual-roller systems can also combine a solar fabric and a blackout fabric at the same window if you want both functions in one installation.
Choose Blackout Shades If
You want the room as dark as possible, you need dependable nighttime privacy, the room is mainly used for sleeping, you’re covering a nursery or media room, or you don’t need to preserve the outside view while the shade is down.
Choose Solar Shades If
You want to reduce glare without making the room dark, you want to keep natural daylight, you want to preserve the outside view, the room receives strong daytime or afternoon sun, or you want UV protection for floors and furnishings while keeping the space open and bright.
Consider Both If
You want filtered daylight and views during the day but full privacy at night, the same room needs strong sun control and sleep-level darkness, or a solar shade alone wouldn’t meet your nighttime privacy needs.
Frequently Asked Questions
Are blackout shades completely dark when closed?
The fabric itself blocks light, but light can still leak around the edges depending on the mount. An outside mount or side channels can reduce edge light if maximum darkness matters.
Do solar shades provide privacy at night?
Not reliably. They offer good daytime privacy because it’s brighter outside than inside, but that reverses after dark when interior lights are on.
What openness percentage should I choose for a living room?
5% is a common middle ground for general living spaces, balancing daylight and view with reasonable glare control. Go tighter, 1% to 3%, for windows with especially strong afternoon sun.
Can I combine blackout and solar shades in the same room?
Yes. A layered setup, a solar shade for daytime glare control plus blackout drapery or a second shade for nighttime privacy, or a dual-roller system combining both fabrics, works well when a room needs both functions.
Do solar shades block UV rays?
Yes. Depending on the openness percentage, solar shades typically block somewhere between 90% and 99% of UV rays, with tighter weaves providing stronger protection.
Choosing Between Blackout Shades and Solar Shades With Lee’s Blinds and Shades
If you’re still deciding, use the room itself to make the choice. Bedrooms, nurseries, and media rooms usually call for blackout. Living rooms, offices, and view-focused spaces usually call for solar shades. And when a room genuinely needs both, layering is a real, practical option, not a compromise.
A professional can help you compare fabric openness, privacy needs, window orientation, and mounting options so the finished shade performs the way you expect. Schedule a consultation and we’ll help you match the right treatment to each room.
