The Sun Zero Barrow is the budget room-darkening pick, a classic rod-pocket panel that reduces light and noise for better sleep at often under $20. It is honest about what it is: Sun Zero rates it as room darkening rather than full blackout, so some light will show through, especially in lighter colors. For a shopper who wants to soften daylight and add privacy and energy efficiency cheaply, it delivers, but those needing total darkness should choose a true blackout panel.
Full review
Real-World Light Blocking
The Sun Zero Barrow is honest about its category: it is a room-darkening panel rather than a full blackout one. Sun Zero's own description is that its room-darkening technology 'reduces light and considerably darkens the room, though some light will show through,' and that performance 'varies based on panel color; the darker the curtain panel, the more light blocking it will be.' This is the key distinction that places it last on a list specifically about blackout.
That said, reviewers find it does its more modest job well. Reviewed.com noted 'the Sun Zero blackout curtains do a good job blocking light,' and the Barrow 'reduces light and noise for better sleep.' If your goal is to take the edge off bright daylight, add privacy, and dim a room rather than make it pitch black, the Barrow delivers, especially in a darker color.
Construction and Feel
The Barrow uses a woven-solid polyester fabric with a classic look, and Sun Zero's panels in this family are noted for a 'plush velvety feel' that drapes nicely, softer and more decorative than a stiff theater-grade blackout panel. It hangs from a rod pocket that fits a rod up to 1.5 inches in diameter, giving a clean gathered appearance.
The fabric is washable and the panels come in a wide range of colors and sizes. The construction is geared toward everyday room darkening and a pleasant hand rather than maximum density, which is consistent with its room-darkening (not blackout) rating, you get a nicer-feeling, more affordable curtain that dims rather than eliminates light.
Noise and Energy Benefits
Even as a room-darkening panel, the Barrow adds practical benefits beyond light. Sun Zero markets it as 'energy efficient,' meaning the fabric helps insulate the window and reduce heat transfer, which can modestly lower energy costs, and it reduces noise for better sleep.
These benefits are more limited than the dense triple-weave blackout panels higher on this list, but they are real, and combined with the low price they make the Barrow a sensible upgrade over a thin, uncoated curtain. For a living room, home office, or any space where total darkness is not required, the noise and energy benefits are a welcome bonus.
Value and Everyday Use
Value is the Barrow's whole story. It is frequently available for well under $20 per panel, making it by far the cheapest option on this list, and for a shopper who simply wants to dim a room and add privacy without spending much, it is an easy yes. Sun Zero is also a widely stocked, well-reviewed brand, so the panels are easy to find and replace.
The rod-pocket header is the main daily-use consideration: it gives a clean look and helps the panel sit flat, but it is less convenient than grommets for frequently opening and closing the curtains. For a window you mostly keep covered, that is a non-issue; for one you open every morning, grommet panels are easier.
How It Compares to Alternatives
The Barrow is the clear value pick but also the clear performance laggard on a blackout list, because it is room-darkening rather than true blackout. The NICETOWN Contemporary Lined Blackout, Amazon Basics Room Darkening Blackout, Eclipse Fresno, and Best Home Fashion Premium Blackout all block 99% to 100% of light, while the Barrow lets 'some light show through' by design.
Its rod-pocket header is similar to the Eclipse Fresno's rather than the grab-and-go grommets on the NICETOWN and Amazon Basics. Where it wins outright is price, it is the cheapest panel here, often less than half the cost of the budget blackout leaders. The honest framing: the Barrow is the right tool for room darkening, the wrong tool for true blackout.
Where It Falls Short
The Barrow's defining limitation is that it is not a true blackout curtain. Some light will always show through, and the amount depends heavily on color, so a light-colored Barrow will let in noticeably more light than a dark one. For a nursery, a shift worker's bedroom, or any space that needs to be genuinely dark, it is the wrong choice.
The rod-pocket header is also less convenient than grommets for daily operation, and the noise and energy benefits, while real, are more modest than the dense blackout panels offer. These are expected trade-offs for the lowest price on the list, but they keep it firmly in last place on a blackout-specific ranking.
Who It's Best For
The Sun Zero Barrow is the right pick for budget shoppers who want to soften daylight, add privacy, and cut some noise cheaply, in a living room, home office, or any space where dimming rather than total darkness is the goal. At often under $20 a panel, it is the most affordable way to upgrade a bare window.
It is the wrong pick for anyone who needs a genuinely dark room, nursery owners, shift workers, or light-sensitive sleepers, who should step up to the true-blackout NICETOWN Contemporary Lined Blackout, Amazon Basics Room Darkening Blackout, or Eclipse Fresno instead.
