How it's made
How a roller blind works
Tap a number to see what each part does, and what you'll be choosing at your appointment.

1. Roller and brackets
The fabric winds onto a tube held by two small brackets, inside the recess or on the wall above it. Which one suits your window is settled when it's measured.
Your advisor brings samples of every option to your window, so you can see and feel them before you choose.
Why this range
What Cassio does well
Built as blackout blinds
Cut and finished as blackout blinds for your exact window, rather than trimmed down from a stock size. The mechanism is sized to the drop, so it hangs straight and stays that way.
5 colourways to compare
Colour behaves differently in north light, in the evening and against your walls. Pick the ones you like here and your advisor brings those exact swatches to the visit.
Measured and fitted by us
One team measures, makes and installs. If something isn't right, there's nobody to pass you on to — we come back and sort it.
Style notes
What Cassio is like, and where it works
Cassio is a plain-woven roller blind range with a fine horizontal texture that gives it more depth than a flat fabric. It comes in blackout-backed colourways from soft neutrals through to charcoal, and is available as an electric option for windows and doors that are awkward to reach.
A textured, subtly striated weave that reads as plain from a distance, shown here in a soft blush-toned neutral and a charcoal grey with a slight linen-like grain running horizontally.

Ideas for your home
Made-to-measure roller blinds for a pair of French doors
A living room with French doors flanked by narrow side panels, grey velvet seating and a glass coffee table, where matching blinds across all three openings keep the look uniform.
The blackout backing means the panels look consistent whether raised or lowered, which matters when several blinds sit side by side.
Made-to-measure roller blinds for a home office
A small desk area by a window, with plants, books and a lamp on the sill, suited to a darker textured tone that doesn't compete with a busy desktop.
A textured charcoal blind adds a bit of depth to a plain window without introducing pattern or colour to distract from the workspace.
- Blackout backing is included across the range's colourways, so all of them block light rather than just filter it.
- An electric version is available for this range, useful for doors, high windows or multiple blinds operated together.
- The horizontal texture is fine and subtle in person; the close-up swatch shows it more clearly than the room photos.
