Most vertical blind listings are exactly what they appear to be: a fabric, a fan of neutrals, a ladder of sizes. Cloud at Blinds By Post keeps its most interesting feature in the shade names. Read those rather than just the swatches and two product titles repeat across the range: plain Cloud, and Cloud Blockout Duo. That second title is the tell. Blackout-capable louvres are a genuine rarity in the vertical world, which mostly trades in light-filtering weaves, and here they sit inside an ordinary-looking range of 9 colourways from £13.19, flagged only by a Duo prefix on the shade name.
Who it suits
Verticals earn their keep on wide glass. Patio doors, sliding doors, full-height landing windows and long office runs are the spans where a single roller becomes unwieldy and curtains swallow the floor, and where louvres let you meter daylight by tilting rather than lifting. The standard Cloud shades suit exactly that brief in living rooms, dining rooms and home offices: tilt for privacy, swing the stack aside when you want the garden back.
The Duo shades change the audience. A blockout louvre makes a vertical a serious candidate for bedrooms behind sliding doors, for nurseries with wide windows and for anyone who sleeps in daylight hours - the jobs that normally force a choice between the practical blind and the dark room. Be realistic about the physics, though: louvres overlap rather than seal, so slivers of light can still find the joins and the edges. The cloth itself stops light passing; total cinema darkness needs more than any vertical can promise.
The colours
9 colours available
The palette splits into two camps that mirror the two cloths. The plain Cloud side keeps to soft window staples - White, Beige and Cream - shades that disappear politely into most schemes. The Duo side covers similar ground in blockout form with Duo White, Duo Cream and Duo Grey, then stretches further than most blackout palettes bother to: Duo Black for a properly dark louvre, and Duo Red, which is not a colour anyone expects to meet in a blockout vertical. The repeated names are useful rather than lazy. Because a cream and a white exist on both sides of the range, you can hang the standard cloth in the lounge and the Duo version in the bedroom next door, and the house reads as one scheme from the street while each room gets the light behaviour it needs.

Vertical pricing follows the glass: width drives the louvre count, drop drives the fabric length, so a patio-door span naturally costs more than a boxy landing window in the same shade. The from-price belongs to the smallest sizes, and the table above is the fastest route to an honest figure for your measurements - checked against the specific shade you want, since the standard and Duo cloths are listed as their own variants.
How it compares
Cloud is not exclusive to Blinds By Post. The same range name is sold at 1Click Blinds, Blinds Direct and Vertical Blinds Direct, and the pattern that follows every shared name applies here too: each shop makes up and prices the fabric independently, so the same window in the same shade can come to noticeably different totals depending on where you order. Our Cloud vertical comparison puts the current versions side by side, and it is the two-minute check this range deserves before you commit. Within Blinds By Post itself, Cloud's pitch is the pairing: plenty of verticals will dress a patio door and plenty of blackout rollers will darken a bedroom, but one range that does both while keeping its colours consistent is a shortcut to a coherent house.
A note on care
Louvres want little more than regular dusting: a soft brush, or the vacuum on its gentlest setting, run top to bottom with a hand behind the fabric. Marks lift with a barely damp cloth and patience - blot rather than scrub, and let the louvre dry hanging straight. If your louvres carry bottom weights and connecting chains, keep them linked so the vanes hang true, tilt with the wand or chain rather than by hand, and never fold a louvre back on itself; a crease in a stiffened fabric tends to be a permanent one.
Likely the same fabric, at other retailers
Cloud vertical blinds are sold under the same name by more than one UK retailer, and the price scales identically across window sizes - a strong sign it is the same fabric from the same supplier:
- Blinds By Post this page from £13.19
- Blinds Direct from £14.25
- Vertical Blinds Direct from £19.95
- Wilsons Blinds from £23.47
- 1Click Blinds from £45.26
We match these on the shared name and an identical price curve, not an independent inspection, so treat it as likely the same fabric rather than confirmed - and check the specification and colour at each retailer before buying.
