Tilt Against The Water
Glare on the Gold Coast often doesn’t come out of the sky. It comes up off a canal, a pool or the ocean, and on a canal-front house in the afternoon it arrives at an angle no roller blind can do much about: a roller is either down or it isn’t.
A venetian can be aimed. Tilt the slats so the edge nearest the glass sits higher than the edge nearest the room, and light coming up off the water hits the underside of each slat and goes back out. You still see the sky and the trees, and nobody on the path below can see in. Reverse the tilt at night, close them flat, and the room is private.
The trade-off is salt. Venetians have more working parts than any other blind we fit — a ladder on every slat, a tilt mechanism, a cord lock — and salty air gets at all of them. Ladder and tilt wear first, long before the slats do, which is why the venetian blind guide spends a section on humidity and salt air. Near the water, aluminium and PVC handle it; timber is happier a few streets back, in rooms that stay dry.
It is still the only blind on the wall that lets you choose which direction the daylight goes. Most people only ever use two settings. That’s fine — they’re the two that matter.
