Deconovo Pencil Pleat Blackout Curtains (Black) – Thermal Insulated Energy Saving, 66 x 84 Inch, Two Panels
Product description
If you’re fed up with early-morning light sneaking in, pencil pleat blackout curtains are one of the simplest upgrades you can make. This Deconovo set is aimed at proper light blocking, with an energy-saving angle for day-to-day comfort.
Key features and what they’re meant to do
On paper, these Deconovo Pencil Pleat Blackout Curtains Bedroom are built for two jobs: helping you sleep more uninterrupted and taking the edge off temperature swings. The blackout claim sits at a high efficiency range (95%–99%), designed to block early morning light, street lamps, and car headlights. That’s the kind of detail that matters if you’re a light sleeper, work shifts, or you just want a darker room for a lie-in.
They’re also described as thermally insulated and “energy saving”. The idea is fairly straightforward: reduce heat loss in winter and block heat in summer so the room feels more stable through the year. You won’t turn a bedroom into a sealed greenhouse, but if your curtains are currently doing very little, this is the sort of upgrade that can make the everyday difference feel noticeable.
What to expect from the blackout performance

The selling point here is the fabric’s ability to block light, plus the thicker, dense build that’s also positioned as improving privacy. The curtains are meant to limit outside views, which is handy if you’re facing neighbours, busy streets, or just want a calmer, more private feel in the bedroom.
A practical way to think about it: imagine it’s 6am and the streetlight is still glaring through your current curtains. With this kind of blackout construction, you should expect far less spill than you’d get from lighter, decorative curtains.
It’s worth keeping expectations sensible though. “Blackout” can vary in real rooms depending on window fit, gaps around the frame, and how the curtain sits on the rail—so if you’re very sensitive to any stray light, you may still want to consider how well you can close off the sides.
Thermal insulation and energy-saving claims


These curtains are described as thermal insulated and energy saving, with the goal of improving indoor temperature comfort year-round. The language focuses on reducing heat loss in winter and limiting heat gain in summer.

If you’re shopping with energy bills in mind, it helps to frame these as a support system rather than a miracle fix. Curtains can reduce drafts and heat transfer, but other factors (window type, insulation, room layout) still play a bigger role. Still, as part of a broader “make the room more comfortable” approach, this is a credible direction.
Fabric, comfort and everyday care
The curtains are made from 100% polyester and are OEKO-TEX certified, with a soft-to-touch feel mentioned alongside durability. That blend matters because it’s not just about blocking light, it’s also about living with the curtains day to day.
For maintenance, they’re machine washable. That’s a practical win in a bedroom or nursery where you want an option that doesn’t require special handling.
Installation and fit considerations (where people often trip up)

They use a pencil pleat heading, which—according to the description—is intended to suit both poles and tracks. That should make installation feel reasonably straightforward, but fitting accuracy still matters.
You’ll want to get the width right: the guidance is to choose a curtain width around 1.5–2 times your pole, and measure the drop from pole to your desired length. This isn’t just “nice advice”—it’s often the difference between curtains that sit properly with a full look and curtains that feel oddly slack.
Also, a small note: this listing is for curtains only, with accessories not included.


Who it suits best (and who might want to look elsewhere)
It makes sense if you’re looking for blackout bedroom curtains that focus on stronger light control, plus a thermally insulating angle. They’re also positioned as a good fit for shift workers, light sleepers, and anyone who values privacy.

It might not be the best match if your main priority is maximum thermal control above everything else, or if you need a very specific mounting setup and don’t want to buy the rail/track parts separately. If you can’t achieve a decent curtain spread (or you’re expecting perfect darkness with no side gaps), you may find the results fall short of your personal “complete blackout” standard.

Is it worth it?
Buy these if you want a straightforward blackout upgrade for a bedroom (or similar room) where early light, street lamps, or car headlights are a problem—and you like the added idea of thermal insulation for year-round comfort. The pencil pleat styling is classic, and the machine-washable, soft-to-touch polyester should suit everyday living.


Skip or look closer at alternatives if your window setup is likely to leave unavoidable side gaps, because blackout performance in the real world depends heavily on fit. And if you already have a good curtain layout and you’re only after a tiny improvement, the difference may feel more incremental than transformative.
