Blackout curtains in Bangkok: how to actually sleep past sunrise

There's a particular kind of Bangkok morning nobody warns you about. It's six o'clock, the sky is already the colour of a swimming pool, and a blade of sunlight is lying across your pillow as though it pays rent. If you've ever typed "blackout curtains Bangkok" into your phone at some ungodly hour — half awake, mildly furious — you're in good company. It's one of the most asked and least usefully answered questions among people who've recently moved here.

So let's answer it properly, for this city and this sun.

Why the tropical sun is a different problem

Bangkok sits close to the equator, which changes the maths of a morning. The sun comes up early and it comes up bright — a little after six, more or less all year, with none of the long, forgiving dawns you might be used to further north. There's no gentle grey hour to doze through. One minute it's dark; the next, your bedroom is lit like a shop window.

Then there's the heat. That same low morning sun pours straight through the glass of a sun-facing condo, and by the time you've given up on sleep, the room is already warming up and your air-conditioning is quietly working overtime. Blocking the light and blocking the heat, it turns out, are the same job.

Off-the-shelf curtains and the light-gap problem

Here's the thing most people discover the hard way: a ready-made "blackout" curtain rarely delivers a blacked-out room. The fabric itself might be perfectly opaque. The trouble is everything around the edges.

Off-the-shelf panels come in standard widths and drops, so they almost never match your actual window. That leaves a bright halo down each side, a glowing line along the top where light leaks over the rail, and a gap at the floor. You bought darkness and got a picture frame of daylight instead. In a bedroom, those side gaps are the real enemy — a single finger of sun at the edge is enough to wake you.

This is precisely why we don't sell curtains off a shelf. We measure the window on site, then make each pair to fit it: the right drop so they meet the floor, enough fullness so the fabric folds rather than stretches flat, and a heading — the top band that gathers the fabric — wide enough to close those side gaps for good. Our made-to-measure curtains and soft furnishings are cut, sewn and hung by our own team — the difference between a curtain that looks dark and a room that actually is.

Blackout, dim-out or sheer — what the lining really does

Most of the darkening happens in a layer you never see: the lining behind the face fabric. It's worth knowing the three you'll be choosing between.

• Blackout lining is the serious one. A tightly woven, light-tight backing that stops the sun cold — the right call for bedrooms, nurseries and anyone working nights who needs to sleep through a bright afternoon.
• Dim-out lining takes the edge off. It cuts most of the light without sealing the room into total darkness, which suits a living room or study where you want glare and heat controlled but not a cinema.
• Sheer fabric does the opposite on purpose — it filters the harsh midday sun into something soft and liveable while keeping your daytime view. Many homes layer a sheer with a blackout behind it, so one window can be gauzy by day and pitch dark by night.

There's no single right answer. There's a right answer for each room, and that's the honest conversation to have before anything is made.

More than darkness: heat, UV and the dust question

A good lining earns its keep long after sunrise. Blackout and dim-out linings come in energy-efficient weaves that hold heat out during the day, so a sun-facing room stays cooler and your aircon stops fighting the window. In a top-floor Bangkok condo that difference is not subtle.

The same fabric shields your furniture, floors and artwork from the UV that quietly fades everything it touches. And because Bangkok is a dusty city — anyone who's run a finger along a windowsill knows the feeling — we can specify anti-dust finishes across the range, so the curtains that darken your room aren't also collecting the street. Practical, not just pretty.

Curtains and walls, chosen together

Here's something a curtain-only shop can't do for you. Because we dress walls and windows both, we choose your curtains and your wallcovering as one decision — matching tone, texture and weight so the room reads as a whole, not a collection of good intentions. A heavy blackout drape against the wrong wall can feel like a barricade; against the right one, it grounds the whole scheme.

Our fabrics come through Ashley Wilde, whose contemporary weaves give you real range — the airy Arden voiles and textured plains for filtering light, the deeper Aubrey weaves when you want a curtain with presence. You can feel your way through the full fabric library with us, from ฿1,500–3,500 per square metre, in daylight and against your own walls, before committing to anything.

Quick answers

Do blackout curtains help with heat?

Yes — noticeably, when they're lined for it. An energy-efficient blackout or dim-out lining keeps the day's heat out of a sun-facing room and takes real load off your air-conditioning. Sealing the side gaps matters here too: trapped air behind a well-fitted curtain acts as its own quiet layer of insulation.

Blackout or dim-out for a bedroom?

For a bedroom, blackout — especially if you're sensitive to light or sleeping past a bright Bangkok sunrise. Dim-out is the friendlier choice for living rooms and studies, where you want glare tamed but not the room sealed shut.

Can you actually block the light at the sides?

That's the whole point of made-to-measure. By fitting the drop and fullness to your window and running the heading wide, we close the side and top gaps that ready-made panels leave open. It's the part that turns "dark-ish" into genuinely dark.

Ready for a proper night's sleep?

Every window is a little different, and the right answer usually starts with a measurement and a conversation. Tell us about the room that's been waking you up too early — or book a design consultation, in English or Thai — and we'll help you choose the fabric, the lining and the fit that finally let you sleep past sunrise.
