Description

Most blackout roller blinds only stop light passing through the material itself. They do not prevent light leakage around the edges. That’s why many bedrooms are still dim not dark.

This made‑to‑measure blackout system seals each potential gap individually, creating a genuinely dark room rather than a slightly dimmed one.

Designed for Better Sleep & Total Darkness

Ideal if you need uninterrupted, reliable darkness:

  • Bedrooms affected by early morning sunlight
  • Nurseries and baby rooms
  • Shift workers sleeping during the day
  • Gamers and media rooms
  • Home cinemas

If you need a true blackout blind for sleeping, this system is built for that purpose. You can also view our range of solar screens which block up to 80% of the sun’s heat and about 75% of the UV which keep heat out of rooms If you need to keep midges out please look at our fly screen section. Our 30 x 20 Genuine Midge Mesh also reduces heat from the sun by up to 65%.

How the Blackout System Works

In short it works like a roller blind, but with a fully sealed cassette and side guide system.

The System Explained

  • Blackout material is rolled onto a tube inside an aluminium head cassette
  • The cassette is fitted between the side walls or directly onto the window frame
  • Side guide channels are fixed beneath the cassette and run down both sides
  • An optional magnetic lower closing channel seals the bottom edge for 100% blackout
  • Feefo Platinum Trusted Service Award Winner

Simple Everyday Use

Using the blind is straightforward:

  • Pull the handlebar down over the window
  • The blind locks securely in place
  • Gently ease the handlebar backwards to release
  • The blind retracts smoothly into the cassette

You can also view our step‑by‑step installation and how it works video in the product image gallery.

Optional Intermediate Clips – Wake Naturally

Add intermediate clips to control how much light enters the room.

With clips installed, you can:

  • Set the blind to a pre‑determined position
  • Allow light to enter gradually
  • Introduce ventilation while maintaining privacy
  • Create a more natural waking routine

Perfect for children’s bedrooms or anyone who prefers gradual light instead of sudden brightness. 

Suitable for Windows, Roof Lights & Velux Windows

Made to measure for:

  • Standard vertical windows
  • Roof windows
  • Angled glazing
  • Velux‑style windows

Ideal for bedrooms, loft conversions and anywhere complete darkness is required.

Does this blackout blind block 100% of light?

Yes. When fully installed with the side guide channels and optional magnetic closing channel, the system blocks external light from all four sides of the window not just through the fabric. This creates a genuine total blackout environment.

What makes this different from a standard blackout roller blind?

Standard blackout blinds only prevent light passing through the material. They do not stop light leaking around the edges.

This system uses sealed side channels and a cassette enclosure to eliminate edge light gaps, making it a true blackout blind system rather than just blackout fabric.

Is it suitable for Velux or roof windows?

Yes. This blackout blind is suitable with each blind made to measure for a precise fit.

Is it easy to install?

Yes. The blind is supplied fully assembled with all fixings and printed instructions.

Most customers complete installation using basic household tools. No specialist experience is required. 

Or contact our customer service who will be happy to help.

Can I leave the window open with the blind fitted?

Yes. With optional intermediate clips, you can position the blind partially open to allow ventilation and controlled natural light while maintaining privacy, however we do not recommend leaving windows open when the blind is fully down.

How long does delivery take?

Each blind is made to measure in Buckinghamshire, so dispatch times are typically shorter than many made-to-measure alternatives. Free delivery to mainland UK addresses is included with every order.

Is this suitable for shift workers or nurseries?

Absolutely. This blackout blind system is ideal for:

  • Shift workers sleeping during daylight
  • Babies and young children
  • Bedrooms affected by early sunrise
  • Home cinema rooms

It creates reliable darkness at any time of day.

Does it come with a warranty?

Yes. Every blind includes a 2‑year warranty for peace of mind.
