Modern homes embrace natural light, yet nobody enjoys glare on the TV, faded furniture, or feeling exposed when the sun goes down. As smart window‑treatment pioneers at Beasen, we constantly hear from people who want the perfect balance of daylight, privacy and efficiency.
Should you opt for light‑filtering fabrics that bathe rooms in a soft glow, or the enveloping darkness of blackout shades?
What does “light filtering” mean?
When we talk about light‑filtering curtains or shades, we are referring to fabrics that allow a portion of sunlight to pass through while diffusing glare. Unlike sheer curtains, which barely soften light, light‑filtering fabrics are tightly woven or have a subtle texture that cuts brightness. At Beasen, our light‑filtering shades come in different levels of opacity - 50 %, 70 %, or 85 % - so you can choose how much glow you want.
What are light‑filtering curtains or shades made from?
Typical light‑filtering shades use woven polyester, linen blends or bamboo. The weave creates tiny gaps that diffuse harsh sunlight but maintain a bright ambience. For example, our Smart Motorized Light Filtering Roller Shades (50 % blackout - Sierra Translucent) are made from a textured fabric that filters half of the incoming light while offering privacy. Light‑filtering cellular shades (also called honeycomb shades) have pleated cells that trap air for insulation; you can select fabrics that are sheer, semi‑opaque, or room-darkening.
Benefits of light‑filtering window treatments
- Soft natural light: Light‑filtering shades gently diffuse sunlight so your space feels warm and inviting without harsh glare.
- UV protection: Filtering fabrics block a portion of UV rays, protecting carpets and artwork from fading. Our solar shades are specially woven to block up to 99 % of UV radiation while still allowing daylight.
- Energy efficiency: Sunlight that enters through standard double‑pane windows becomes heat; the U.S. Department of Energy estimates about 76 % of sunlight that strikes a window turns into heat inside. Light‑filtering shades reduce solar heat gain, keeping your home cooler and reducing air‑conditioning use.
- Daytime privacy: Semi‑opaque fabrics obscure views from outside during the day, giving you privacy without darkening the room. According to North Solar Screen, transparent mesh solar shades provide daytime privacy but less at night.
Can you see through light‑filtering shades at night?
It depends on the fabric’s opacity. Highly transparent materials like sheers and many solar shades provide little privacy when interior lights are on. To keep prying eyes out after dark:
- Layer a light‑filtering shade with blackout drapes or curtains.
- Choose a tighter weave: A lower openness factor (1 %–3 %) in solar shades reduces visibility.
- Opt for dual or day‑night shades: Our Smart Motorized Dual Shades - Light Filtering & Blackout combine both fabrics on one headrail so you can switch between open view and privacy.
What are blackout shades?
Blackout shades are designed to block almost all light. By using dense fabric and light‑blocking liners, blackout shades create a dark environment regardless of the time of day.
Benefits of blackout shades
- Improved sleep quality: WebMD highlights that blackout curtains allow shift workers and people sensitive to light to rest in darkness, improving sleep quality.
- Total privacy: Blocking light means blocking the view. Blackout materials offer the best coverage for privacy, day or night.
- Reduced glare: Eliminating sunlight makes them ideal for media rooms or home theatres.
- Enhanced insulation: Thick fabrics and liners help control heat flow. Insulated cellular shades can reduce heat loss by 40 % or more and cut solar heat gain by up to 60 %.
Light‑filtering vs blackout: what’s the difference?
The key distinction is how much light passes through. Light‑filtering treatments allow soft illumination and preserve views, whereas blackout shades create near total darkness. The table below summarises the differences:

Do you need room‑darkening or light filtering? What about “room darkening” shades?
You’ll often see a third term - room darkening. These shades fall between light‑filtering and blackout. They block more light than semi‑opaque fabrics yet don’t achieve complete darkness. They are ideal if you want to dim a room without turning it into a cave, for example, in a home office or a child’s playroom. Many of our motorized zebra shades offer 80–85 % blackout while still letting slivers of light through for ambiance.
Room function and time of day
Choosing between light‑filtering and blackout depends on how you use each room. Bedrooms and nurseries benefit from blackout for better sleep, while kitchens and living rooms thrive with soft natural light. If you often nap in the afternoon or have a media room, blackout is the clear winner. For morning spaces like breakfast nooks, light‑filtering shades soften harsh early sun.
Orientation and window exposure
Think about where your windows face. West‑facing rooms receive intense afternoon sun, which can overheat a space. Light‑filtering solar shades with a low openness factor (1 %–3 %) cut glare and heat. East‑facing bedrooms catch early morning sun, so blackout shades help extend sleep. North‑facing windows often need insulation more than shading; honeycomb blackout shades provide both.
Light filtering vs solar shades: are they the same?
Light‑filtering shades are not the same as solar shades. Solar shades use a screen‑like fabric woven from vinyl, polyester or fibreglass that lets you see out while blocking UV rays. Their openness factor (1 %, 3 %, 5 %, etc.) determines how much light and view you retain. Light‑filtering roller shades, by contrast, use opaque fabric to diffuse light and usually provide more privacy. If preserving your view is important, solar shades may be a better fit; if you want a cozy glow and better nighttime privacy, choose light‑filtering fabrics.
How do different shade styles handle light filtering and blackout?
Roller shades
Motorized Roller shades are simple and versatile. At Beasen, you can choose from light‑filtering, room‑darkening or 100 % blackout fabrics. Our Smart Motorized Roller Shades - 100 % Blackout Meridian create total darkness with a sleek cassette valance and remote control options.
If you love a gentle glow, our Smart Motorized Light Filtering Roller Shades (70 % blackout - Linen Translucent) filter sunlight while maintaining privacy. You can even select the roll orientation - standard roll keeps fabric close to the glass, while reverse roll hides the roller for a clean look.
Cellular or honeycomb shades
Cellular shades combine insulation and light control. According to Beasen’s guide on honeycomb shades, about 30 % of a home’s heat can escape through windows in winter and 76 % of sunlight becomes heat in summer. Cellular shades use pleated cells to trap air and slow heat transfer.
They come in sheer, light‑filtering, room‑darkening and blackout fabrics. Double‑cell designs increase insulation and noise reduction. You can even choose top‑down/bottom‑up operation for flexible light control. Check out our Motorized Light Filtering Cellular Shades Hex and Motorized Blackout Cellular Shades to compare.
Zebra or dual shades
Motorized Zebra shades (also called dual or combi shades) use alternating bands of sheer and opaque fabric. As you roll them, the bands overlap to create either an open view or a closed, room‑darkening effect. This makes them perfect if you’re torn between light filtering vs blackout shades. Our Smart Motorized Dual Shades - Light Filtering & Blackout offer both fabrics on one shade, so you can align the bands for soft daylight or rotate them for privacy and darkness.
Woven wood shades
Woven wood shades bring natural texture into your home using bamboo, grasses and reeds. The weave’s density determines how much light passes through. We offer 50 % and 70 % light‑filtering woven woods as well as blackout linings, and even Tessa and Lume series where you can pick 50 %, 70 % or 100 % blackout. Pair them with a motorized headrail and a fabric valance to add elegance.
Drapery and curtains
Curtains often require lining to achieve blackout. At Beasen, our Motorized Dual Drapery - Sheer & Blackout combines a sheer layer and a blackout curtain on one track. Motorization means you can open and close them with a remote or voice command. We also offer fabrics that range from 50 % to 100 % blackout so you can tailor them to each room.
Why energy efficiency matters
Windows are often the weakest point in your home’s thermal envelope. The U.S. Department of Energy highlights that about 30 % of home heating energy is lost through windows and 76 % of incoming sunlight turns into heat. Insulated shades help by reducing heat transfer.
Cellular shades trap air pockets, while blackout fabrics with thermal linings provide another barrier. Properly timing when you lower shades also affects comfort and costs; Beasen’s guide notes that lowering blinds at the right time blocks unwanted heat in summer and traps warmth in winter.
Which rooms benefit from each type of shade?
- Bedrooms & nurseries: Blackout shades or room‑darkening cellular shades support restful sleep and daytime naps.
- Living rooms & kitchens: Light‑filtering shades create a bright, welcoming atmosphere. Solar shades with 3 %–5 % openness maintain your view while cutting glare.
- Home offices: Consider light‑filtering cellular or roller shades to reduce screen glare. Dual shades let you switch to blackout during video calls.
- Media rooms: Blackout roller or dual shades eliminate glare for movie nights. If you have large glass doors, choose blackout drapery or motorized dual drapery.
- Bathrooms: Privacy is paramount. Blackout cellular shades resist moisture and provide insulation.
- Street‑facing windows: Blackout or room‑darkening shades prevent passers‑by from seeing in. For daytime use, pair with a sheer curtain for versatility.
Hybrid solutions: Do you have to choose?
Sometimes you want the best of both worlds. That’s where dual or day‑night shades shine. At Beasen, our Motorized Day/Night Skylight Cellular Shades let you transition between light filtering and blackout on skylights. Dual roller shades pair a solar screen with a blackout layer so you can enjoy views during the day and privacy at night. These options are perfect for spaces that double as work areas and guest rooms.
Final thoughts: finding your perfect balance
Choosing between light-filtering and blackout shades comes down to how you want each room to feel. Light-filtering shades bring in a soft glow, while blackout shades give you privacy, darkness and better comfort for sleep or screen time.
At Beasen, we make it simple with smart motorized shades, blackout roller shades, light-filtering options, dual shades and swatch samples, so you can choose the right level of light, privacy and style for every space.
