A blockout roller reads as dark only when it is wider than the reveal — the overlap matters more than the fabric.
A roller blind is the simplest thing we make and, done properly, one of the hardest to beat. A single flat sheet of fabric winds onto a tube behind a neat headbox or cassette. There are no folds to gather dust, no slats to dust individually, and nothing to go out of alignment.
Blockout fabric has a coated back that stops light rather than filtering it. In Sandhurst that puts it in bedrooms, guest suites, media rooms and any room where a projector or a late sleeper is involved. The fabric itself is only half the job: light escapes around the edges long before it comes through the cloth, so the honest fix is a generous overlap onto the wall, or side channels where the room needs to be genuinely black.
On tall Sandhurst openings — and there are plenty — we spec a heavier tube so the fabric hangs dead flat, and past roughly 2.4m wide we would normally motorise. A blockout blind at that size is more weight than anyone wants to pull twice a day.
Practical notes
- Coated blockout fabrics in a range of neutral tones; samples brought to the measure.
- Side channels or a deep overlap where the room must be properly dark.
- Double brackets let a blockout and a sunscreen share one window.
- Child-safe chain tensioners as standard; cordless and motorised options for nurseries.
