Cellular blinds

Cellular and honeycomb blinds

Pleated fabric folded into honeycomb cells that trap a layer of air against the glass — the quiet insulator of the range.

Look at a cellular blind from the side and you can see how it works. The fabric is pleated and joined so that each pleat forms a closed hexagonal cell, and every one of those cells holds still air between the room and the glass. Still air is a poor conductor — which is the whole trick.

In practice that means two things in a Rivonia house. On a cold highveld night, a bedroom with a big single-glazed window loses a lot of its warmth straight through the glass; a cellular blind slows that down noticeably. On a hot afternoon it works the other way, holding some of the heat at the window instead of letting it roll into the room.

They are also the tidiest blind we fit when raised. The pleats collapse into a very shallow stack, so a cellular blind takes up less of the window than almost anything else — useful on a smaller complex window where every centimetre of view counts.

Fabrics run from light-filtering to blockout, and a top-down/bottom-up configuration is available where you want the top of the window open for light and the bottom closed for privacy — a genuinely clever answer for a bathroom or a ground-floor bedroom facing a walkway.

Honest expectation. A cellular blind improves a window; it does not turn single glazing into double glazing. It is a real, measurable improvement, not a miracle — and it is the best you can do to a window without replacing it.

The practical detail

How we specify it here

Small decisions that decide whether you like the blind in two years’ time, not just on installation day.

  • Cell size — smaller cells for narrow windows, larger cells where the window is generous and insulation is the point
  • Blockout backing — available where the room is a bedroom first and an insulation problem second
  • Top-down / bottom-up — light in at the top, privacy at the bottom — the answer for bathrooms and walkway-facing rooms
  • Cordless lift — no loose cord at all, which makes them a natural choice in a nursery
  • Tight reveal fit — the closer to the glass, the better the insulating cell performs

Not sure which fabric or which room? That is exactly the conversation the free measure is for — samples held against your own light beat any swatch on a screen.

Questions

Asked most often

Straight answers, including where the answer is “it depends on the room”.

Do they really make a difference to the temperature?

Yes, and most noticeably on the windows that are worst: large panes, single glazing, a room that gets cold overnight or hot by mid-afternoon. It is an improvement you feel rather than a number we are going to invent for you.

Are they suitable for a bathroom?

They are, particularly in the top-down/bottom-up configuration. In a room with heavy steam and no extraction, aluminium venetians remain the more forgiving choice.

How do you clean them?

Gently. A vacuum on the lowest setting with a soft brush head along the pleats, and a hairdryer on cool to blow dust out of the cells. They do not take kindly to scrubbing.
