Yakamok Thermal Blackout Curtains Review (2026)
Last updated July 2026
For sleepers who want a dark room and lower energy bills in one purchase, the Yakamok Thermal Blackout Curtains stand out with triple-weave, thermally backed faux-linen panels. At $38 (MSRP $58) they earn an exceptional 9.5/10 temperature score and a 4.5 rating from nearly 68,000 buyers. Best for anyone in a hot or cold climate who wants strong light blocking with a premium fabric look. Check price on Amazon.
Overview
Blackout curtains are one of the highest-impact, lowest-cost upgrades you can make to a bedroom, and Yakamok’s thermal panels aim to do double duty: block light for better sleep and insulate the window to save on heating and cooling. They use a two-layer, triple-weave construction with a thermal backing, which is what enables both the light blocking and the insulation. The fabric itself has a soft faux-linen texture, giving it a more upscale look than the flat, rubbery blackout panels many people picture.
The performance claims are grounded and specific. The curtains block 95 to 99 percent of light depending on the color you choose, carry an R-2.5 equivalent thermal rating, and come in a range of sizes from 42 inches wide by 63 inches long up to 52 by 108 inches. They hang from 1.6-inch inner grommets with a silver backing. The honest framing is that these are thermal-first curtains that block most, but not necessarily all, light, and how much light they block depends heavily on the color. At $38 with a huge, positive review base, they are a strong value in the category.
Specifications
| Spec | Detail |
|---|---|
| Material | Faux linen with thermal backing |
| Light Blocking | 95-99% (color dependent) |
| Sizes | Multiple (42”W x 63”L to 52”W x 108”L) |
| Header | Grommet (1.6” inner) |

How It Scored
| Dimension | Score |
|---|---|
| Comfort | 8.5 / 10 |
| Support | 7 / 10 |
| Durability | 8 / 10 |
| Value | 9 / 10 |
| Temperature Regulation | 9.5 / 10 |
| Motion Isolation | 7 / 10 |
Temperature regulation leads at 9.5, the headline strength and the reason to choose these over a plain blackout panel. Value at 9 is close behind, reflecting a lot of fabric and performance for $38. Comfort at 8.5 speaks to the soft faux-linen hand feel and the darker, quieter room they create. Durability at 8 indicates well-made panels that hold up to regular use. The support and motion scores are less meaningful for curtains and mostly round out the profile, though the dense fabric does dampen some outside noise.
Thermal Insulation
This is the standout, and the 9.5 score is the highest across this entire batch for any dimension. The triple-weave thermal backing turns the curtain into an insulating barrier at the window, which is where a huge share of a room’s heat is lost in winter and gained in summer. The R-2.5 equivalent rating means the panels meaningfully slow heat transfer, keeping warm air in during cold months and blocking radiant heat during hot ones. The practical payoff is twofold: a more stable, comfortable bedroom temperature for sleeping, and lower energy bills. The insulation effect is most dramatic on single-pane windows, where there is the least existing insulation to begin with.
Light Blocking
Blocking 95 to 99 percent of light is excellent, but the honest detail is in the phrase color dependent. Darker colors absorb more light and get you toward that 99 percent figure, delivering a genuinely dark room ideal for shift workers, light-sensitive sleepers and daytime nappers. Lighter and lighter-toned colors, while still blocking a strong majority of light, let a bit more through and will not achieve true blackout. If a pitch-dark room is your top priority, choose a darker shade; if you want a bright, airy color, accept that you are trading a few percentage points of light blocking for the aesthetic. This is the single most important buying decision with these curtains. Check the current price and color options on Amazon.
Fabric, Look and Feel
The faux-linen texture is a real differentiator. Many blackout curtains achieve their darkness with a stiff, plasticky coating that looks cheap up close; Yakamok instead uses a soft, woven-look fabric with the thermal layer built in behind it, so the room-facing side looks like an upscale linen drape. The silver grommet backing is a nice touch that adds to the tailored look. Two honest caveats come with the fabric: the panels can feel slightly stiff when brand new, and they tend to arrive with packing wrinkles that need steaming or hanging out to relax. Both settle with a little time and are typical of dense thermal curtains.
Installation and Fit
The curtains use a grommet header with 1.6-inch inner grommets, which slide directly onto a standard curtain rod for quick, no-hardware hanging and a clean, evenly pleated look. The honest limitation is that grommets are the only mounting style; there is no rod-pocket option, so if you specifically want the gathered, rod-pocket look or need to mount on a track, these will not fit that plan. With multiple sizes from 63 up to 108 inches long, most standard and tall windows are covered. For the best light blocking and thermal seal, size the panels wider than your window and mount the rod a few inches above and beyond the frame so light cannot spill around the edges.
Who Should Buy It
These curtains suit comfort-and-savings-minded sleepers. Buy them if:
- You want energy savings on heating and cooling.
- You live in a climate with hot summers or cold winters.

Who Should Skip It
Skip them if:
- You need 100 percent blackout and only want a light color.
- You want a rod-pocket header instead of grommets.

Frequently Asked Questions
How much can I save on energy bills?
Depending on your climate and energy costs, thermal blackout curtains can reduce heating and cooling costs by 10 to 25 percent. The insulation effect is most noticeable on single-pane windows, which lose and gain the most heat.
Do these fully block all light?
They block 95 to 99 percent of light depending on color. Darker shades get closest to full blackout, while lighter colors let a little more light through, so choose a darker color if a pitch-dark room is your priority.
How do I get the wrinkles out?
Hang the panels and let them relax, or steam them lightly. Dense thermal curtains commonly arrive with packing creases that ease out within a few days of hanging.
Will they fit my curtain rod?
They use a grommet header with 1.6-inch inner grommets that fit most standard curtain rods. For the best light seal, choose panels wider than your window and mount the rod above and beyond the frame edges. Note there is no rod-pocket option.
Bottom Line
The Yakamok Thermal Blackout Curtains are a smart dual-purpose upgrade: a darker room for better sleep and real insulation that trims energy bills. Their one true limitation is that light blocking depends on color, so committed blackout seekers should pick a dark shade, and rod-pocket fans should look elsewhere. For soft faux-linen panels that carry a category-leading 9.5/10 temperature score at $38, the value is excellent. Check the latest price on Amazon.
