Blackout Shutters — Enhanced Darkness with an Integrated Cellular Blind
Blackout Shutters combine our interior shutter panels with an integrated cellular blockout blind, fitted within the shutter frame for substantially enhanced darkness and greater light reduction than shutters alone. This is not a Total Blackout solution, and some residual light may remain depending on the installation.
Blackout Shutters combine our interior shutter panels with an integrated cellular blockout blind, fitted within the shutter frame to give substantially enhanced light reduction and greater darkness than shutters alone. This is not a Total Blackout solution — some residual light may still remain, depending on the installation and configuration.
On one of our verified shutter systems, the blockout blind is a 25mm white cellular fabric fitted behind the shutter panels within a four-sided shutter frame. The cellular fabric blocks light passing through the material itself and has an internal foil wrap, and its honeycomb structure also supports thermal insulation — though a small clearance around the blind relative to the frame means the system should never be described as sealed or gap-free.
At Blinds Kingdom we supply and fit Blackout Shutters across Milton Keynes, Bedford and Luton. Every installation begins with a free home visit, where we bring samples, take accurate measurements and confirm exactly what your chosen shutter material and range can achieve.
Why Choose Blackout Shutters?
Enhanced Darkness for Light-Sensitive Rooms
The integrated cellular blockout blind sits behind the shutter panels, working alongside them to substantially reduce light beyond what shutters alone can achieve.
The Elegance of Shutters, Unchanged
The blind is fitted within the shutter frame, so the shutter panels keep their usual look and operation when extra darkness isn't needed.
Independent Control
The shutter louvres and the cellular blind can be adjusted separately, giving you daylight control and darkness as two distinct options rather than one compromise.
An Added Thermal Benefit
The honeycomb structure of the cellular blind traps air within its cells, which can help with thermal insulation alongside its light-reducing role.
Available on Selected Materials
The integrated blackout option is confirmed on selected Composite, Paulownia wood, Wood Grain Paulownia and ABS-coated Paulownia ranges, with exact availability confirmed during survey.
How Blackout Shutters Work

Blackout Shutters bring together two separate elements, working as one system within a single four-sided frame. The shutter panels operate exactly as a standard shutter, with louvres that tilt open and closed to control daylight and privacy in the usual way.
Behind the shutter panels, within the same frame, sits the integrated cellular blind. It can be lowered independently of the louvres for substantially enhanced darkness — the two elements are operated separately, working together rather than as a single mechanism. As set out below, this is not a Total Blackout solution.
The exact frame and blind configuration depends on the shutter material and range selected — confirmed during survey.
How it works
Blackout Shutters Are Not Total Blackout
It's an important distinction, and one we want to be upfront about before you order.
Standard Shutters
Shutter louvres and panels control daylight and privacy, but are not designed to exclude light when closed — light passes around and between louvres in the usual way.
Blackout Shutters
Adding the integrated cellular blockout blind behind the shutter panels substantially increases light reduction and creates enhanced darkness. A small clearance around the blind means some residual light can still remain, depending on the installation and configuration.
Total Blackout Blind
A separate, purpose-designed framed screen product. On qualifying dark grey or black configurations, correctly surveyed and installed, it can achieve full blackout — genuine total blackout is supported on that product, not on shutters.

The Integrated Cellular Blockout Blind

One of our verified shutter systems uses a 25mm white cellular blockout blind, fitted behind the shutter panels within the shutter frame. The honeycomb cells block light passing through the fabric itself and include an internal foil wrap, and the same honeycomb structure supports thermal insulation.
A small clearance remains around the blind relative to the shutter frame, which is why the system is described as substantially enhanced darkness rather than a sealed or gap-free installation. Other verified shutter systems may vary in their exact blind construction and clearance — your surveyor will confirm the specification that applies to your chosen range.
Well Suited to Bedrooms and Light-Sensitive Rooms

Blackout Shutters are well suited to rooms where reducing incoming light matters — bedrooms, nurseries, home cinema and media rooms, and rooms used for daytime rest such as shift-work sleep.
The shutter louvres and the integrated cellular blind work together to give you daylight control and enhanced darkness in the same system, without needing a separate blind fitted alongside your shutters.
Available Materials
The integrated blackout option is confirmed on selected ranges within these materials. Availability depends on the specific range, dimensions and configuration — confirmed during survey.
Wooden→
Selected Paulownia wood ranges support a dedicated blackout blind frame, subject to the configuration and dimensions selected.
Composite→
Selected Composite ranges can be combined with an integrated blackout blind behind the shutter panels, subject to survey.
Wood Grain→
Selected Wood Grain Paulownia ranges also support the integrated blackout option — availability confirmed during survey.
ABS-Coated Paulownia→
Selected ABS-coated Paulownia ranges support the integrated blackout option. This is a coated finish within our wooden shutter range — availability confirmed during survey.
Frame and Window Divisions Matter
Blackout Shutters always require a four-sided shutter frame, so the blind can be housed and guided correctly within it — this differs from some standard shutter installations that don't need a frame on every side.
On the verified system described here, a single blind opening is supported up to 1600mm wide. Wider openings require a T-post — a vertical divider that splits the window into separate blind openings, each with its own blind — up to a maximum overall width of 3500mm with T-posts fitted. Minimum blind width is 300mm, minimum height is 300mm, and maximum height is 2000mm.
These figures are specific to the verified system described here — other shutter ranges and materials may have different size and configuration limits. Your surveyor will confirm the exact frame layout, T-post requirement and size limits that apply to your windows.
Louvre sizes
Louvre Sizes
63mm, 76mm and 89mm louvres are available with the integrated blackout option. 114mm louvres are not currently available with this option.
63mm louvres
A smaller louvre giving a more traditional shutter appearance while still supporting the integrated blackout blind.
76mm louvres
A mid-size louvre giving a good balance between view-through when open and coverage when closed.
89mm louvres
A larger louvre giving fewer, wider slats and a bolder appearance.
What We Check During Survey
Your surveyor measures each window opening and confirms whether a single blind or a T-post split configuration is needed, based on the verified width limits for your chosen system.
We confirm which of your selected shutter material and range supports the integrated blackout option, the available louvre sizes, the frame requirements, and whether manual or electric operation is available for your configuration.
If you need the strongest possible light exclusion — beyond what an integrated cellular blind can offer — your surveyor can also talk you through our dedicated Total Blackout Blind system as an alternative.
What Level of Darkness Should You Expect?
Blackout Shutters are designed to substantially reduce light and give you a noticeably darker room than shutters alone — but as set out above, this is not a Total Blackout solution. A small clearance around the integrated blind means some residual light can remain, particularly around the edges of the frame.
How dark your room becomes depends on your specific installation — the shutter material and range, the window size and configuration, and whether a T-post split is required. Your surveyor will give you an honest assessment during your home visit, and will point you towards our Total Blackout Blind system if genuine total blackout is what you need.
