Two Blinds. One Bracket. Total Control.
Most windows only need one blind. But some rooms ask for a bit more. Maybe you want to let the morning light in gently without losing privacy. Maybe you need the room properly dark at night but bright and airy during the day. That’s exactly what a double roller blind is built for.
A double roller blind puts two separate roller blinds into a single cassette. One fabric at the front, one at the back — each with its own chain, each working completely independently. You choose when to use each one and how much of each you want down at any given time. During the day, you lower the sheer or light-filtering layer and enjoy soft, diffused daylight while keeping the room feeling open and private at the same time. At night — or whenever you want total darkness — you bring down the blackout layer and shut it all out.
It’s a proper dual-purpose solution in one neat, tidy system. No faffing with two sets of brackets, no cluttered window frame, no compromise on how the room looks. Just one clean, well-designed blind that does both jobs.
At Perfect Blinds UK, our double roller blinds are made to measure for your exact windows. We come out to measure up for free, and our team fits everything for you at no extra charge. All you need to do is pick your fabrics — and we’ll bring samples with us to help you do exactly that.
Why Choose Double Roller Blinds
You get two blinds in one
The whole point of a double roller blind is flexibility. Most window coverings make you choose — either you’ve got something that lets light in, or something that blocks it out. A double roller blind doesn’t ask you to choose. The sheer fabric at the front softens daylight and gives you daytime privacy from neighbours or passers-by, while the blackout layer behind it can be pulled down whenever you want genuine darkness. You use one, the other, or both together depending on what the room needs at that moment.
Brilliant for bedrooms
This is probably where double roller blinds earn their reputation most. During the day you want the room to feel light and pleasant. At night you want proper darkness for a decent sleep. A single standard blind struggles to do both — a blackout blind makes the room feel gloomy during the day, and a light-filtering blind doesn’t do much for darkness at night. A double roller blind solves that straight away. It’s one of the most practical things you can do for a bedroom window.
Great for living rooms too
Living rooms get used at all sorts of times, and the light changes throughout the day. A double roller blind lets you control that properly. In the morning you might want the sheer down to reduce glare on the telly without losing daylight. In the evening you might want the blackout layer down for a bit more privacy. You’re in control of how the room feels at any point, without needing to fiddle with multiple window coverings.
Reduces glare on screens
If you work from home or spend a fair amount of time in front of a screen, glare is a genuine annoyance. A sheer or screen fabric layer on a double roller blind takes the edge off harsh sunlight without plunging the room into darkness. It’s a much more practical solution than trying to juggle curtains or constantly adjusting a single blind throughout the day.
Looks clean and smart
Despite doing the job of two separate blinds, a double roller blind looks neat and tidy. Everything is contained within one bracket system above the window. There are no extra fixings on the wall, no visible brackets from the second blind, and no messy layering. When both blinds are fully raised, it sits at the top of the window just like a standard roller blind. Clean lines, minimal fuss.
Made to fit your windows exactly
Off-the-shelf double roller blinds are even more of a compromise than standard ones, because the two-fabric system leaves even less room for error. Having yours made to measure means both layers fit your window properly, with no awkward gaps at the sides and no overlap that catches on the frame. We take care of all the measuring when we visit, so you don’t need to worry about getting it wrong.
Things Worth Knowing
Each blind has its own chain
The two fabric layers are controlled by two separate chains or motors — one for the front blind and one for the back. It’s worth being aware of this before you order so you can think about which side you’d like chains on — we’ll talk you through it when we come out to measure up.
The bracket sits slightly further out from the window
Because two roller tubes need to sit one behind the other, the cassette’s brackets and endcaps are a deeper than a standard single bracket. This is worth knowing if you’re planning to fit face-fix above a narrow recess, or if you’ve got any obstacles like curtain poles, handles, or trickle vents close to the top of the window frame. It’s rarely a problem, but it’s something we check for during the measuring visit.
Light can still come in at the sides
Just like a standard free hanging roller blind, a double roller blind won’t create a completely sealed blackout. There will be small gaps at the sides, particularly in a recess fitting. For most bedrooms and living rooms this is absolutely fine — the blackout layer will do a proper job. But if you need total darkness, let us know and we can talk through the options.
Fabric colour matching varies slightly between layers
Because the two fabrics have different light properties — one is sheer or semi-transparent, the other is blackout — the same colour can look slightly different on each layer. This is completely normal and something every manufacturer acknowledges. When you choose your fabrics, we’ll make sure you pick a pairing that works well together in your room.
They’re easy to keep clean
Both layers clean the same way as any roller blind fabric — a light vacuum with a brush attachment for dust, and a damp cloth for any marks or spills. There’s no complex mechanism to clean around, and the fabrics don’t need any special products. Just let them dry fully before rolling them back up and they’ll stay looking good.
Not suited to unusual window shapes
Like all roller blinds, the double roller system works on standard rectangular windows. Sloped, curved, or unusually shaped windows won’t be a good match.

Common Questions (FAQ)
What's the difference between a double roller blind and a Day and Night blind?
A Day and Night blind — sometimes called a zebra blind — uses one piece of fabric with alternating solid and sheer stripes that shift as the blind is adjusted, giving you a spectrum of light control in a single layer. A double roller blind uses two completely separate fabrics on two separate tubes, so you can use each one fully or independently. They’re both great options — it really comes down to how you prefer to control the light in a room.
Can I use two different fabrics for my double roller blind?
Yes, and that’s the whole point. The front layer is typically a sheer, voile, or light-filtering fabric, while the back layer is a blackout or dim-out fabric. We’ll show you fabric combinations that work well together when we visit for the measuring appointment.
Are double roller blinds suitable for bathrooms and kitchens?
They can be, but you do need to choose moisture-resistant fabrics for both layers. We stock appropriate options, so it’s worth mentioning it when you get in touch so we can make sure we bring the right samples.
Will a double roller blind fit in my window recess?
In most cases, yes — but the double bracket is slightly deeper than a standard roller bracket, so we always check for any obstacles or tight fits during the measuring visit. It’s one of those things that’s best confirmed in person before anything is ordered.
Do you fit double roller blinds across South Yorkshire?
Yes. We cover Barnsley, Sheffield, Rotherham, Wakefield, Leeds, Bradford, Halifax, Huddersfield, Pontefract, and the surrounding areas. Free measuring and free fitting are included as standard.
Can the blinds be motorised on one layer only?
It’s possible to motorise both layers independently, giving each one its own remote or smart control. It’s more common to motorise both at the same time for the best experience, but we can discuss what suits your situation best when we come out to see the windows.
Make Them Even Better
Motorisation
Motorising a double roller blind is one of the best upgrades you can make. Instead of two separate chains to manage, you get two blinds that operate at the touch of a button — or a voice command if you’ve got a smart home setup at home. Each blind can be set to raise and lower independently, so you can programme the sheer to come down in the morning and the blackout to drop at night without lifting a finger.
It’s especially useful for windows that are a bit awkward to reach — above a sofa, over a kitchen worktop, or higher up on a wall. It also makes a real difference for anyone who finds operating chains difficult, whether that’s down to mobility, age, or simply personal preference. Our motorised roller blinds are compatible with remote controls, wall switches, and smart home systems including Alexa and Google Home.
Cassette headrail
Adding a cassette to the top of a double roller blind conceals both roller tubes and the bracket mechanism completely, leaving just a clean, flat face at the top of your window. It gives the whole thing a much more polished, built-in look — particularly noticeable in living rooms or bedrooms where you want the finished result to look genuinely considered rather than just functional. Available in several colours to match your window frames or room décor.
