MRTREES Sky Blue blackout thermal curtains with eyelets (2 panels, 52x84 inch)

What these curtains are for

If your room feels too bright in the afternoon or a bit too drafty when the weather turns, blackout thermal curtains are one of those fixes that can actually make day-to-day life more comfortable. The MRTREES Sky Blue blackout thermal curtains come as room divider-style panels with eyelets, aimed at bedrooms and living rooms where you want both light control and temperature help.

On paper, they’re designed to tackle two common issues at once: blocking a meaningful amount of light and reducing temperature loss/gain by limiting air movement around the window. They’re not marketed as “soundproof” or anything like that, so it’s worth keeping expectations realistic: this is about light and insulation, not turning your home into a sealed bunker.

Key points

You get two thermal blackout panels in a sky blue tone, each with eyelets for easier hanging on a curtain pole (the inner diameter of each ring is roughly 4 cm, which should suit most typical poles). The fabric is described as a three-layer construction, and it’s designed to block around 65% of light—more so with darker colours, though this one is a lighter blue.

For energy bills, the selling angle is prevention of temperature leaks in both summer and winter. In real terms, that usually means fewer noticeable drafts and less heat escaping through gaps around the window—especially if the curtains sit neatly when closed.

What to know before buying

There are a few practical details worth checking so you don’t end up disappointed.

First, the coverage: you’re buying 2 panels, each listed as 132 cm wide and around 213–214 cm long (the naming includes 52x84 inch and the description states 132x213 cm). Depending on how wide your window is and whether you like curtains to overlap, you may find you need more panels for full coverage.

Second, light blocking isn’t described as absolute blackout. Around 65% is decent for reducing brightness, but if you’re specifically trying to create a “proper dark room” for daytime sleeping, you may still notice ambient light.

Finally, colour and packaging quirks happen: the colour may look slightly different depending on screens, and after long transport the curtains could have a mild odour when first unboxed. That should fade after you hang them for a while.

The fabric and light/temperature performance

The curtains use a three-layer fabric technology. The manufacturer claims this can block about 65% of light, and the darker the colour, the more light it can block. Since this set is sky blue, it’s likely to be better at softening daylight than fully eliminating it.

On temperature control, the idea is that thermal curtains can help prevent heat leaks in summer and winter. Thermal curtains typically work best when they hang close to the window and reduce gaps—so if your poles or fittings leave space around the edges, the insulation effect may feel less dramatic than expected.

Everyday use and practicality

These are “easy-care” curtains. The care instructions are straightforward: machine wash under 30 degrees with a neutral detergent, no bleaching, and if there are creases you can either hang them for a while or iron on a low temperature until they relax.

In day-to-day terms, the eyelet design makes them simpler to slide onto a pole and adjust. A quick micro-scenario: if you pull the curtains across in the evening to reduce glare on the TV, you’ll likely notice the room feels calmer and less washed-out, in colder weather, closing them at night may reduce the chill near the window.

That said, they can’t fix everything—if the window has big gaps, broken seals, or poor insulation, curtains are an assist, not a full replacement.

Pros

• Two-panel set, with a sky blue colourway suited to bedrooms and living rooms
• Thermal, three-layer construction is aimed at reducing temperature leaks
• Eyelet rings for straightforward hanging on a curtain pole
• Practical care: machine washable under 30 degrees and no bleaching
• Light blocking is described as around 65%, which should help with glare

Cons / where it may fall short

• “Blackout” here sounds more like “significantly reduces light” rather than full darkness (around 65% is stated)
• The shade is lighter blue, so compared with darker curtains it may block less light
• Coverage depends on your window width and overlap preference, two panels might be enough or might not
• Mild shipping odour and slight colour differences due to screens are possible

Tech specs

• Care instructions: machine wash below 30 degrees, neutral detergent, no bleaching, steam/hang to release creases or iron on low

What it suits (and who should avoid it)

It makes sense if you want a simple curtain solution for bedrooms and living rooms that can soften incoming light and help reduce heat loss/gain around the window.

It might not suit you if you’re chasing near-total darkness for shift work, babies’ daytime naps, or very light-sensitive sleep. Also, if you need guaranteed full coverage across a wide window, you should double-check how your window width compares to 2 panels and whether you want overlap.

Should you buy it?

Worth considering if you’re after thermal blackout-style curtains that are easy to hang and care for, with a fabric build aimed at cutting light glare (around 65%) and helping with temperature leaks. You’ll get the most out of them when they hang close to the window and you like a lighter sky blue look.

Better avoided if you need true blackout levels of darkness or you know your window is wider than what two panels with your desired overlap can cover.

Mini FAQ

Will these curtains completely block out light?

The description states they can block around 65% of light, so they should reduce brightness and glare, but they’re unlikely to create full darkness.

What size are the panels?

Each panel is listed as 132 cm wide and about 213–214 cm long (also shown as 52x84 inch in the product name).

Are the eyelets compatible with most curtain poles?

Each eyelet’s inner diameter is roughly 4 cm, which is described as suitable for most curtain poles—still, it’s sensible to compare with your pole before ordering.

How do you wash them?

Machine wash below 30 degrees with a neutral detergent and no bleaching. Creases can be reduced by hanging after washing or ironing on a low setting.

Why does mine smell when I open the pack?

The description mentions a slight odour after long transport. It should fade after hanging the curtains for a while.
