The best blackout and thermal curtains depend on how much light you need to block, your window size, and how you want to hang them. Joydeco is the strongest choice for shoppers seeking a stated 100% blackout liner, while Hiasan emphasizes thermal insulation and included tiebacks. COSVIYA and NICETOWN offer darkening options in specific panel sizes. Compare the listed dimensions and hanging styles before choosing: curtains that are too narrow or short may leave gaps around the window.
| Product | Best For | Notable Feature |
|---|---|---|
| Joydeco Nature Linen | Maximum stated light blocking | 100% blackout liner and two hanging options |
| Hiasan Dark Grey | Thermal comfort and flexible styling | Thermal claims and sewn-on tiebacks |
| COSVIYA Navy Blue | Wider windows and longer drop | Two 52-by-84-inch panels |
| NICETOWN Grey | Shorter windows and TV rooms | Triple-weave fabric and two panels |
| NICETOWN Black | Dark-colored room-darkening panels | Two 42-by-63-inch panels |
Joydeco Nature Linen Blackout Curtains
These 84-inch curtains are best for bedrooms or living rooms where strong light blocking and a textured linen-style appearance are priorities. The product description states that a dedicated liner blocks 100% of sunlight and UV rays. It also describes the panels as thermal insulating, privacy-enhancing, and noise reducing.
The set has two panels and offers both rod-pocket and back-tab hanging options. Choose this pair if you want more flexibility in how the curtains sit on a standard rod. The heavyweight faux-linen fabric is intended to provide a soft drape and a more substantial look.
Consider: The listed length is 84 inches, so check your window and desired hem position before ordering. Full blackout results also depend on how completely the curtains cover the window.
Hiasan Dark Grey Thermal Curtains
Hiasan is best for buyers who want curtains described as thermal, with a practical way to hold them open. The 42-by-63-inch dark grey panels are marketed as blocking light and helping keep out winter chill and summer heat. The listing also says they can help reduce distracting outside noise and provide privacy.
Two tiebacks are sewn onto the curtain sides, so the panels can be held open without separate hardware or drilling. This makes the set a useful choice for a bedroom, office, or entertainment room where adjustable light and privacy matter.
Consider: The product description does not state a specific percentage of light blocked. Choose it for its stated features, but do not assume it provides total blackout.
COSVIYA Navy Blue Grommet Curtains
COSVIYA is best for shoppers needing longer panels or broader combined coverage. The set includes two 52-by-84-inch panels, for a stated total width of 104 inches. Each panel has eight silver metal grommets with a 1.6-inch inner diameter, and the listing says they slide smoothly on rods.
The unlined polyester fabric is described as soft, lightweight, and smooth. COSVIYA states that the curtains block 85% to 99% of sunlight and UV rays, with darker colors performing better. The navy color and room-darkening claim make these a reasonable choice for a bedroom where some light reduction is sufficient.
Consider: These are unlined panels, and the listed light reduction is not a promise of complete darkness. Check that your rod fits the grommets.
NICETOWN Grey Triple-Weave Curtains
These grey NICETOWN curtains are best for shorter windows, television rooms, or shoppers seeking a two-panel set with grommet tops. Each 42-by-63-inch polyester panel has six grommets. The product description says the unlined fabric feels soft and heavy and uses triple-weave technology.
The listing claims 85% to 99% light and UV-ray reduction, with darker colors working better. It also describes the panels as noise reducing and helpful for better TV viewing. Choose this option if the dimensions fit your window and you want grey curtains with room-darkening features.
Consider: The listed light reduction is a range, not total blackout. Grey may not block as much light as darker shades according to the product details.
NICETOWN Black Grommet Curtains
This black NICETOWN set is best for buyers who want dark-colored, shorter panels for a bedroom or TV room. It includes two 42-by-63-inch polyester panels, each with six grommets. The unlined fabric is described as soft and heavy, with triple-weave construction.
NICETOWN states that the curtains impede 85% to 99% of light and UV rays. The listing also identifies noise reduction and improved TV viewing as benefits. Choose black if you prefer a darker color and the dimensions suit your window.
Consider: These panels are not described as 100% blackout. Their 63-inch length may not cover taller windows.
Buying Guide: How To Choose Blackout And Thermal Curtains
What level of light blocking do you need?
Check whether a listing describes room darkening or total blackout. COSVIYA and both NICETOWN options state 85% to 99% light reduction, while Joydeco claims 100% blocking from its dedicated liner. These are product claims, and light can still enter around uncovered edges. For a darker room, measure for enough width and length to cover the window.
Which size and hanging style fit your window?
Compare each panel’s width and length with your window, then consider how much overlap you want. COSVIYA provides two 52-by-84-inch panels; the NICETOWN sets are two 42-by-63-inch panels. Joydeco offers rod pockets and back tabs, while COSVIYA and NICETOWN use grommets. Hiasan includes sewn-on tiebacks.
How should you compare thermal features?
Look for explicit insulation language rather than assuming every blackout curtain provides the same thermal performance. Hiasan says its panels help keep out cold in winter and heat in summer. Joydeco describes its lined curtains as helping regulate room temperature year-round. The supplied product details do not provide measured energy savings.
Do color and fabric matter?
Color can affect light reduction: COSVIYA and NICETOWN specifically say darker colors work better. Fabric construction also differs. Joydeco has a dedicated liner and faux-linen texture, while COSVIYA and NICETOWN describe unlined polyester panels. Match the look and construction to your room as well as your light-control needs.
Frequently Asked Questions
Do blackout curtains block all light?
Not always. The listed products make different claims, and light may enter around the sides, top, or bottom if the panels do not fully cover the window.
Are thermal curtains useful in both summer and winter?
Some product descriptions say they help limit heat transfer in both seasons. Hiasan states that its curtains help keep out winter chill and summer heat, but the listing provides no measured energy savings.
How many panels come in these sets?
All five listed options are described as two-panel sets. Check the dimensions because their panel widths and lengths differ.
What is the difference between grommets and rod pockets?
Grommets are openings set into the top of a curtain for a rod to pass through. A rod pocket is a sewn channel, while Joydeco also offers back tabs as another hanging option.
Which option is described as blocking 100% of sunlight?
Joydeco claims that its dedicated liner blocks 100% of sunlight and UV rays. The other products listed describe partial light reduction or room-darkening performance.
