The short answer: sheer curtains filter daylight and give you daytime privacy without darkening a room. Blackout curtains block light almost completely and cut the heat coming through the glass. In most Dubai homes the right answer is not one or the other — it is both, on a double track.
That sounds like a sales line until you have lived through a Dubai August. A west-facing window here takes direct sun from about three in the afternoon until sunset, on a day that may touch 45°C. A single sheer will not help you sleep at 6am in June, and a single blackout panel means choosing between a dark room and a hot one.
In most Dubai homes the right answer is not one or the other. It is both, on a double track, so you can choose room by room and hour by hour.
What a sheer curtain actually does
A sheer is a lightweight, open-weave fabric — voile, linen sheer, or a textured polyester — hung in front of the glass. It does three things.
It diffuses the glare. Direct Gulf sunlight is harsh. A sheer spreads it so the room is bright without hot spots on a screen or a sofa.
It gives daytime privacy. From outside in daylight, a sheer reads as opaque. After dark, with the lights on, it does not — which is the part people discover too late.
It softens the window. A bare window in a tall villa room looks unfinished. Sheers add height and fall.
What a sheer does not do is stop heat. Light passes through, and so does a good part of the solar gain. If your AC runs hard in the afternoon, sheers alone are not the answer.
Fabric note: pure linen sheers drape beautifully and look expensive, but they move with humidity and can hang slightly longer in summer. Polyester and linen-blend sheers hold their length and colour better against UV, which matters on a window that takes six hours of sun a day.
What a blackout curtain actually does
Blackout is not a fabric. It is a lining — a dense, usually three-pass coated backing sewn behind your face fabric. That means you can have blackout performance in almost any fabric you like, including a pale linen that looks nothing like a hotel curtain.
A properly made blackout curtain darkens the room so you can sleep past sunrise, which in Dubai is before 5:30am in June. It cuts heat transfer through the glass, because the lining is a second barrier between the window and the room. And it deadens sound slightly, which is useful on Sheikh Zayed Road and less so in a quiet villa compound.
Where blackout goes wrong. Most complaints that blackout curtains do not work are not about the fabric. They are about light leaking around the edges. The curtain is too narrow and stops at the reveal instead of extending well past the window. The track is fixed above the frame instead of at the ceiling, so there is a glow at the top. Or there is not enough fullness, and a flat panel leaks at the folds — the fabric should be two to two and a half times the track width.
These are fitting decisions, not fabric decisions. A ready-made panel cannot make them for you.
The Dubai problem is heat, not just light
In a cooler climate the curtain conversation is about darkness and draughts. Here the window is the hottest surface in the room for much of the year. Single glazing in older Dubai buildings makes this worse, and so does a large sliding door onto a balcony.
This is why the two-layer approach is not a luxury here. In the daytime you close the sheers and leave the blackout open: soft light, privacy, glare controlled. At the afternoon peak you close both on the sun-facing windows, and the room stays usable while the AC stops fighting the glass. At night you close the blackout for a dark room and a cooler morning.
One track, two layers, three different settings. You cannot do that with a single curtain.
Room by room
Bedrooms — blackout, no debate. If there is one room to get right, it is this one. Blackout lining, ceiling-fixed track, generous overlap at the centre and at both ends. Add a sheer in front if the room is also used during the day. For children, the same applies with one addition: cordless or motorised operation, so there is no looped cord within reach.
Living room — sheers in front, blackout behind. The living room is used across the whole day, so it benefits most from the double layer. A pale sheer keeps the room bright and private in the afternoon; a heavier lined curtain behind handles evening glare and the hot hours.
Majlis — weight and presence. A majlis is usually a formal room with tall windows, and the curtain is part of the architecture. Heavier fabrics work here, in pinch pleat or goblet pleat headings that hold a deep fold. Blackout lining is worth it even if the room is used mostly in the evening, because it protects the fabric and the furniture from the sun during the day.
Kitchen — neither, usually. Full-length curtains in a kitchen collect cooking oil and smell. A Roman blind or a roller in a wipeable fabric is the better answer, and it leaves the counter clear.
Home office — glare first. The enemy here is reflection on a screen, not darkness. A good sheer or a light-filtering roller usually beats a heavy curtain. If the room faces west, add blackout so afternoon video calls are possible.
Bathrooms — moisture rules. Avoid natural fibres. A synthetic sheer or a moisture-tolerant blind lasts far longer in a room that gets steam twice a day.
If you can only have one layer
Sometimes the budget or the window only allows one. A rough guide.
Cannot sleep past sunrise — blackout. Neighbours can see in during the day — sheer. Room too hot in the afternoon — blackout, with lining. Screen glare — sheer, or a light-filtering roller. Room feels bare and cold — sheer, floor length. Baby napping — blackout, cordless.
The two measurements people get wrong
Two numbers decide whether a curtain looks made to measure or made elsewhere.
Track width, not window width. The track should run well past the glass on both sides so the curtain stacks clear of the window when open. A curtain that sits over the glass when open is stealing your light and your view.
Drop from the track, not from the frame. Fix at or near the ceiling and let the fabric fall to just off the floor. Starting at the top of the window frame makes the whole room look shorter.
For wave and S-fold headings a ceiling-recessed track is close to essential, because the look depends on an uninterrupted line. For pinch pleat, a decorative pole can be the better choice in a traditional room.
What it costs
Curtain pricing in Dubai varies more than people expect, and almost all of it comes down to three things: the fabric, the fullness, and the lining. The same window can differ by several times over depending on whether you choose a basic polyester at minimum fullness or a linen at full fullness with blackout lining and a motorised track.
Anyone quoting a single price per window before seeing the window is guessing. We measure on site first, then quote, and there is no charge for the visit or the measurement.
Frequently asked questions
Do sheer curtains give privacy at night?
No. In daylight a sheer reads as opaque from outside, but once it is dark outside and your lights are on, the effect reverses and the room is visible. If the window faces a walkway or a neighbouring villa, you need a second layer.
Can I get blackout in a light-coloured fabric?
Yes. Blackout is a lining sewn behind the face fabric, so a pale linen or a soft beige can be fully blackout. The lining blocks the light, not the colour you see.
What is the difference between blackout and dimout?
Blackout lining stops effectively all light. Dimout, sometimes called room-darkening, reduces it substantially but leaves a soft glow. Dimout is often enough for a living room; bedrooms are usually worth full blackout.
How much fabric do I need for a good fold?
Between two and two and a half times the track width for most headings. Less than that and the curtain hangs flat and looks thin, whatever the fabric cost.
Will blackout curtains reduce my AC bill?
They reduce heat coming through the glass, which helps most on windows that take direct afternoon sun. How much you notice depends on your glazing, the orientation and the size of the opening. It is a real effect, not a dramatic one.
Can sheer and blackout curtains hang on the same track?
Yes. A double track is the standard way to do it, with the sheer in front and the lined curtain behind. It can be manual, or motorised so both layers move independently.
Where to go next
We make custom made curtains to the exact size of your windows in our own Dubai workshop, including double tracks for sheer plus blackout and motorised systems. For a room that needs light control rather than darkness, see wooden Venetian blinds or Roman blinds. For a formal room with tall windows, see majlis curtains.
