Guide · Choosing well
Light and privacy, explained properly
Almost every regret we hear about window treatments traces back to one of two misunderstandings. Both are on this page, and both take two minutes to avoid.
Misunderstanding one
Privacy is directional, and it flips at night.
Any treatment you can see through works by contrast. In daylight the outside is brighter than the inside, so you see out and nobody sees in. After dark, with your lights on, that reverses exactly — and a sheer, a solar shade or an offset layered shade that gave you total privacy at two in the afternoon gives you none at nine in the evening.
This is the single most common source of disappointment in this trade, and it is entirely avoidable. If a room needs privacy after dark — bedrooms, bathrooms, any ground-floor room facing a street — it needs a treatment that is opaque, or a second layer that is. We will always ask what a room is used for before recommending anything see-through in it.
Misunderstanding two
Blackout fabric does not make a blackout room.
Blackout describes the cloth, not the installation. A blackout shade mounted inside the window opening still leaks a rim of daylight around all four edges, because there is a gap between the fabric and the frame. In most bedrooms that is completely fine and people are happy. In a nursery, or for somebody sleeping during the day, it is not.
Getting to genuinely dark needs side channels that trap the edges, or an outside mount that overlaps the opening generously. Both are available and neither is expensive; what matters is deciding which room actually needs it, because a blackout fabric in a living room makes the space read closed even when the shade is up.
Room by room
What we usually recommend.
Starting points rather than rules — your house gets the final say.
- Living roomLight-filtering, almost always. Cellular or Roman for warmth; add a solar shade if a west elevation is making the room unusable in the afternoon.
- Primary bedroomRoom-darkening or blackout, with side channels only if you are sensitive to light. Sheer shades if the light quality matters more than total darkness.
- NurseryBlackout with channels, cordless without exception. This is the one room where we push hard on the specification.
- Kitchen & bathComposite shutters or a wipeable roller. Avoid natural fibres and unlined fabric where there is steam and grease.
- Home officeLow-openness solar shade behind the desk, on whichever elevation is putting sun onto your screen. This is the most reliably satisfying recommendation on the whole list.
- Street-facing ground floorSomething that is opaque after dark, or a top-down configuration that lets light over the top while staying closed at eye level.
Questions
Asked and answered.
What is the difference between room-darkening and blackout?
Blackout fabric passes essentially no light through the cloth. Room-darkening substantially reduces it but is not total. Both still leak around the edges when mounted inside the opening — the fabric name describes the cloth, not the finished darkness of the room.
Can one treatment give me privacy and keep the view?
In daylight, yes — a solar shade does exactly that. After dark, no treatment can do both at once, because privacy after dark requires opacity. Rooms that need both usually get two layers.
What is the most common mistake people make?
Choosing blackout everywhere. It seems like the safe option and it makes living spaces feel closed in, because the fabric reads as solid even when the shade is raised. Blackout in bedrooms, light-filtering nearly everywhere else.
