This fully sealed blackout system blocks light from all four sides of your window creating a genuinely dark room at any time of day.
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.

Specifications
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.
