C.4 · Fabric
Blockout, light-filter or sheer, explained once
Whatever style ends up on the schedule, a roller, a Roman, a curtain, the same three-way fabric decision sits underneath it: how much light should this opening pass? Get this one right per room and half the schedule writes itself.
The three transparencies
| Fabric | Light | Privacy | The view out |
|---|---|---|---|
| Blockout | None through the weave; the room can go properly dark | Total, day and night | None while down |
| Light-filter | Softened daylight comes through; shapes blur | Private by day; silhouettes show at night with lights on | Glow, not a view |
| Sheer / sunscreen | Most daylight passes; glare and UV are cut | Screened by day; near-transparent at night with lights on | Kept, slightly tinted |
The night-privacy catch
The bolded cells above are where fabric choices go wrong. Light-filter and sheer fabrics work by letting light through, and light does not care which direction it travels: after dark, with the room lit, the flow reverses and the street sees in. A sunscreen that made the kitchen private all day becomes a display case at 8pm.
That is not a reason to avoid them; it is a reason to pair them. The rooms you use at night either take a blockout layer behind the soft one, or they accept the trade knowingly (plenty of upstairs rooms and unoverlooked yards can).
Why the dual roller earns its run
The most-specified line on our schedules is two fabrics on one bracket: a sunscreen for the day, a blockout behind it for the night. Bedrooms that would otherwise be caves all day get their light back; living rooms that would otherwise glow after dark get their privacy back. One opening, both jobs. Layered curtains, a sheer with a blockout drape, are the same logic in fabric, and a zebra blind is the same logic in a single material.
Room by room, the usual calls
- Bedrooms: blockout, always, as the base layer. Add a sunscreen (dual roller) or sheer if the room lives a daytime life too. Shift workers and nurseries want the fit checked at the measure; darkness is made at the edges, not just in the fabric. The fit guide covers why.
- Living areas: sunscreen or sheer for the view and the glare, with a blockout or curtain layer where the room faces the street and runs late.
- Kitchens: light-filter holds privacy without dimming the working end of the house. Near the cooktop, think slats rather than fabric at all.
- Media rooms: blockout, face-fitted generously. The daytime case for a dual is stronger here than people expect.
- Home offices: light-filter for even light on the desk; a dark-weave sunscreen where the outlook deserves keeping.
- Bathrooms: privacy is non-negotiable and steam is constant; this is usually a materials question (PVC shutters, aluminium venetians) more than a fabric one.
Two grades of honesty about "blockout"
Blockout describes the fabric, not the room. A blockout roller hung loose in a bright window still leaks a frame of light at every edge; whether that matters depends on the sleeper. Where the brief is true darkness, the schedule says so and the answer involves fit, side channels or an overlapping drape, decided at the window. If a room must merely be dim and private, a standard blockout fit does fine. We write down which of the two you asked for.
