Blackout Blinds

If sunlight is affecting your sleep our blackout blinds are just the ticket! 

Unlike standard blackout blinds for windows that only darken a room, our made to measure blackout blinds use a fully sealed system to eliminate edge light gaps and create complete darkness at any time of day. 

Each blind is made to your exact window size and uses a fitted frame with side channels, a head cassette blackout fabric and optional closing channel to limit brightness around the full window opening. The result is a neater finish and a noticeably darker space ideal for bedrooms, nurseries, shift workers, home cinemas, media rooms and any space where controlling daylight matters.

Made to Measure Roller Blackout Blinds

Many blackout roller blinds rely mainly on the fabric. While blackout material stops light passing directly through the blind, brightness can still appear around the sides, above the roll or beneath the bottom bar.

Streme blackout roller blinds are built differently. The fabric runs within the frame to give a closer fit and better room darkening than an ordinary off-the-shelf blind.

This helps tackle common problems such as:

• brightness around the edge of the blind
• daylight above the roller tube
• light showing below the bottom bar
• poor fit on unusual window sizes
• glare in bedrooms, nurseries and media rooms

For customers who want a more effective alternative to a basic room-darkening blind, a fitted blackout roller blind offers a cleaner and more practical solution.

Because this is a made-to-measure product, please read our measuring guides carefully before placing your order. Accurate measurements are essential to achieve the best blackout performance.

White Blackout Blinds with Side Tracks

Side tracks are one of the key features that separate a specialist blackout blind from a standard roller blind.

Instead of the fabric hanging freely in front of the window, it is guided down both sides to help control brightness where ordinary blinds often struggle. This is especially useful when the sun is low, when streetlights shine directly at the window, or when a room needs to stay dark during the day.

If you are searching for blackout blinds with side tracks, cassette blackout blinds or framed blackout blinds, you are usually looking for the same type of product: a roller blind with extra components designed to improve performance around the edges.

Depending on the design, this may include:

• an enclosed aluminium head cassette
• vertical guide channels
• brush seals
• a lower closing channel
• precision-cut blackout fabric
• a custom fit for your window

Together, these details help deliver a more controlled finish than standard blackout roller blinds.

Total Blackout Roller Blinds 

For total blackout performance, the blind must be sealed on all four edges: top, left side, right side and bottom. To achieve the best possible blackout result, a closing channel can be added to the bottom of the blind. This is an optional paid extra and is designed to receive the bottom bar when the blind is fully closed.

The closing channel helps create a sealed system around all four sides of the blind. This makes it especially useful for bedrooms, nurseries, shift-worker rooms, home cinemas and any room where maximum light control is required.

If you are looking for a total blackout, we recommend selecting the optional closing channel when placing your order. Without the closing channel, the blind will still provide excellent room darkening, but a small amount of light may remain visible at the bottom depending on the window, recess and installation.

Blackout Blinds for Bedrooms

Bedrooms are one of the most popular places to install blackout blinds. Early sunrises, street lighting and long summer evenings can all disturb sleep. A fitted blackout blind can help make the room feel calmer and more restful by limiting unwanted brightness at the window. 

You can also choose to add intermediate clips to control how much light enters the room. Rather than using the blind only fully open or fully closed, the clips can be moved and positioned where required on the side channels. Once set, they allow the blind to rest at your chosen height, so you can partially cover the window while still letting in daylight, perfect for anyone who prefers gradual light instead of sudden brightness or to combat urban light pollution. 

Blackout Blinds for Nurseries and Children’s Rooms

Daytime naps and early bedtimes can be difficult when a child’s room is still bright outside. This is especially common during spring and summer.

A made-to-size white, blackout blind can help create a more consistent sleep setting for babies, toddlers and young children. By keeping the room darker, it can support nap times, bedtime routines and early mornings.

Blackout Blinds for Home Cinemas, Gaming and Media Rooms 

In home cinemas, gaming rooms and media spaces, excess light can affect the viewing experience. Reflections and glare can make screens harder to see and reduce picture quality. Streme blackout blinds help control daylight entering the room, making it easier to create a more immersive space for films, gaming and TV. They are also useful in home offices where glare on monitors can become distracting during the day.

Blackout Blind FAQs

How does the blind fit around the window?

A closer fit usually means better room darkening and a neater appearance.

What are intermediate clips and how do they help with light control?

Intermediate clips allow you to position your blackout blind at different heights, giving you flexible control over natural light throughout the day. The clips can be moved and set within the side channels, allowing the blind to stop at your chosen point rather than only being fully open or fully closed. This makes it easy to reduce glare, improve privacy and block direct sunlight while still allowing daylight into the room. Intermediate clips are ideal for bedrooms, nurseries, home offices and media rooms where adjustable light control is useful.

What is the total blackout system and do I need the closing channel?

Our total blackout system is designed to reduce light entering around all four edges of the blind. The head cassette helps seal the top, the side channels help control light along the left and right edges, and the optional closing channel seals the bottom when the blind is fully closed. The closing channel is available as a paid extra and is recommended if you want the highest level of blackout performance. Without the closing channel, the blind will still provide excellent room darkening, but some light may be visible at the bottom edge.

Does it use side channels?

Side channels help guide the fabric and control brightness along the vertical edges.

Is there a blackout blind cassette at the top?

A cassette covers the roller mechanism and improves the finish at the top of the blind.

Is it made to your exact size?

A custom-made blind is better suited to unusual windows and rooms where light control is important.

Can a blackout blind be used for all room types?

Bedrooms, nurseries, shift-worker rooms and home cinemas often need a more specialist solution than a standard roller blind.
