Sunlight entering a room creates multiple problems simultaneously: it heats the space, causes glare on screens and eyes, and accelerates fading in furniture, flooring, and artwork. The right curtain or shade does not just make a room darker - it actively blocks the UV and infrared components of sunlight that do the most damage.
These five picks cover the spectrum from view-preserving solar shades to complete blackout solutions, all optimised for maximum sun blocking.
| Panel | UV Block | View Preserved | Best Room |
|---|---|---|---|
| Coolaroo Indoor UV Blocking Shade | 90% | Yes | Living room / sunroom |
| NICETOWN 100% Blackout UV | 100% | No | Bedroom / nursery |
| Solar Shade 90% UV Block | 90% | Yes | Home office |
| White Reflective UV Curtain | 95%+ | No | South/west facing |
| Eclipse UV Blackout Curtain | 99% | No | Any room |
1. Coolaroo Indoor UV Blocking Sun Shade
Coolaroo’s indoor sun shade takes a different approach to sun blocking - a knitted screen fabric that filters UV and reduces glare while maintaining a partial outward view. Rated at 90% UV blockage, these shades reduce solar heat gain significantly while keeping the room from feeling sealed off. They are ideal in sunrooms, home offices, and living rooms where you want daylight without direct sun exposure.
Pros: Maintains partial view to outside while blocking 90% of UV, reduces glare dramatically without full darkness, cooler appearance than heavy drapes, easy to clean, available in multiple widths.
Cons: Does not provide complete darkness or privacy at night when interior is lit, knitted construction is not soft-draping like traditional curtains, aesthetic is functional rather than decorative.
2. NICETOWN 100% Blackout UV-Blocking Curtain
For rooms that need complete sun elimination - nurseries, bedrooms for night-shift workers, home theatres - NICETOWN’s 100% blackout panel is the definitive solution. The triple-weave construction achieves genuine 100% light and UV blockage with no pinhole light transmission. It also significantly reduces solar heat gain and UV-driven fading of interior furnishings.
Pros: True 100% blackout - no light, no UV, no glare, also provides thermal and noise reduction benefits, available in sophisticated neutral colours that do not look institutional, machine washable and wrinkle-resistant.
Cons: Complete darkness eliminates natural light entirely - not for rooms where some daylight is desired, triple-weave construction feels less natural than linen or cotton alternatives.
3. Solar Shade 90% UV Block Curtain
Solar shades designed specifically for 90% UV blocking occupy the sweet spot between total blackout and unprotected glass. The woven screen material blocks UV and infrared heat while allowing diffused daylight to create a comfortable, glare-free environment. These are particularly effective in home offices where screen glare is the primary problem.
Pros: Optimised specifically for UV reduction, allows comfortable working light without direct sun exposure, significantly reduces solar heat gain compared to standard curtains, available in custom lengths.
Cons: Woven screen fabric does not provide privacy at night, functional aesthetic may not suit all interiors, lower privacy than opaque curtain alternatives.
4. White Reflective UV Curtain Panel
White fabric with a reflective or metallic backing takes a different technical approach: rather than absorbing solar radiation, it reflects it back through the glass before it can enter the room. These panels are most effective on south- and west-facing windows where afternoon sun is most intense. The white face keeps rooms bright and airy while the backing deflects solar energy.
Pros: Reflects rather than absorbs solar radiation - the most efficient heat and UV blocking mechanism, keeps room appearance bright and light, significantly reduces surface temperature of windows and surrounding walls, double-duty: sun blocking in summer, cold barrier in winter.
Cons: Reflective backing faces the window - exterior appearance can be stark, limited decorative colour range due to the reflective coating requirement, may need replacement more often in intense sun exposure.
5. Eclipse UV Blackout Curtain
Eclipse is one of the original blackout curtain brands and their UV-focused blackout line represents decades of refinement. The foam-backed construction provides 99% UV blocking along with full light blackout, and the brand’s wide size range and colour palette make it one of the most versatile sun-blocking options across different room aesthetics.
Pros: Established brand with consistent quality, 99% UV block alongside full light blackout, foam backing adds thermal insulation, wide colour and size range for decorative flexibility, machine washable.
Cons: Foam backing can degrade over time with heavy sun exposure (ironic for a sun-blocking curtain), slightly stiff drape compared to unlined alternatives, heavier than standard panels.
What to Look For
UV block percentage: Look for specific percentages rather than marketing terms like “UV resistant.” 90% UV block is good for most applications; 99-100% is required for nurseries, media rooms, or serious furniture protection.
Coverage without gaps: A sun-blocking curtain with light leaking around the edges provides significantly less UV protection than the fabric rating suggests. Overlap panels at the centre, mount rods wide, and use a return bracket to bring panels flush against the wall.
Solar vs. total blackout: Solar shades (90% UV) preserve your view and create a pleasant working environment. Total blackout panels eliminate all light and UV. Choose based on whether you need daylight or complete sun exclusion.
Final Thoughts
The scale from solar shade to total blackout covers a wide range of sun-blocking needs. For home offices and living rooms, the Coolaroo or solar shade 90% options maintain liveable light levels while eliminating glare and UV damage. For bedrooms, nurseries, or media rooms, NICETOWN’s 100% blackout panel is the definitive solution. Whichever you choose, mount it wide and high for maximum coverage - a curtain’s rating only applies to the area it actually covers.
Frequently asked questions
What percentage of UV does a blackout curtain block?+
A true blackout curtain with a dense opaque lining blocks 99-100% of UV radiation - because there is simply no light passing through the fabric. Solar shades rated at 90% UV block are more nuanced: they significantly reduce UV while maintaining an outward view. For maximum UV protection, full blackout panels are the most effective window treatment.
Do white curtains reflect more sunlight than dark curtains?+
Yes. White and light-coloured curtains reflect solar radiation rather than absorbing it. Dark curtains absorb solar energy, which can warm the curtain itself and then re-radiate heat into the room. For sun and heat blocking, white or silver-backed reflective panels outperform dark-coloured panels of equivalent fabric weight.
Will UV-blocking curtains protect my furniture from fading?+
Yes, significantly. UV radiation is the primary driver of dye degradation in upholstery, wood finishes, and artwork. A 90%+ UV-blocking curtain or solar shade reduces fading dramatically. A 100% blackout panel eliminates it entirely during closed hours. Even partial-day use (closing curtains during peak sun hours) extends furniture life considerably.
