Sheer Roller Blinds

Your lounge has the view, and by three the sun has turned it into a furnace. A sheer roller keeps the daylight and the garden, and loses the heat and the glare.

What are sheer roller blinds?

  1. A finely woven, translucent roller fabric that filters sunlight, cuts glare and most UV, and keeps the view through the window
  2. Two openness factors from Custom Blinds Shutters & Awnings: 3% for stronger heat and glare control, 5% for more view and light
  3. Daytime privacy: you see out, passers-by see little in while it is brighter outside than in. At night with the lights on, that reverses
  4. For a room that needs both, a duo-roller puts a sheer and a blockout on one bracket
  5. Coulisse and Hunter Douglas fabrics, made to measure, priced instantly online with free delivery nationwide; fitted on the Garden Route

  • Sheer roller blinds in a street-facing bathroom

    See-through at night with the light on; a plaswood venetian or honeycomb instead.

    Not alone

04   Privacy at night

The optics reverse after dark.

By day the outside is brighter than the room, so the fabric reads as a screen from the street. At night the room is the bright side and the fabric shows what is behind it. If night privacy matters in that room, fit a duo-roller, sheer in front of blockout, or choose a different blind.

“People think they need blockout blinds for every window. They do not. In a living room with a beautiful garden view, a sheer is the right answer. You keep the light, you keep the view, and you stop the sun cooking your furniture.”
Duncan Kane Founder, Custom Blinds Shutters & Awnings

Questions buyers ask about sheer roller blinds

Do sheer roller blinds provide privacy at night?

No. By day the fabric reads as opaque from outside; at night with interior lights on, people can see in. For night privacy pair a sheer with a blockout on a duo-roller bracket.

What openness factor should I choose for sheer blinds in South Africa?

3% for west-facing windows with harsh afternoon sun and for TV rooms; 5% for east-facing rooms, kitchens and home offices where more light and a clearer view matter. A darker fabric sees through more clearly.

Can sheer roller blinds be motorised?

Yes. Somfy and MotionBlinds by Coulisse motors run them by remote, app or schedule; battery motors need no wiring. Custom Blinds Shutters & Awnings fits and programmes motorised blinds on the Garden Route.

What is the difference between sheer roller blinds and outdoor Sheerweave blinds?

Sheer rollers are indoor blinds in or over the recess. Sheerweave and Sunworker outdoor blinds mount outside the glass in heavier weather fabrics and stop the heat before it reaches the window. Both keep the view.

Are sheer roller blinds suitable for coastal homes on the Garden Route?

Yes. The Coulisse and Hunter Douglas fabrics resist moisture, salt air and UV on powder-coated aluminium headrails; Custom Blinds Shutters & Awnings fits them from Mossel Bay to Plettenberg Bay.
