What the salt air actually does
The Hinges Go First
A marine atmosphere does not stop at the beachfront. The Gold Coast has several hundred kilometres of constructed canals threading salt water through Hope Island, Sovereign Islands, Mermaid Waters and Broadbeach Waters, which is why a house eight kilometres inland can sit in the same corrosive air as one at Main Beach. In a timber shutter the blades take up that moisture, swell against the frame and stop closing flush. The paint film lifts before the timber does.
The part people forget is the hardware. A shutter is blades, a frame, and a set of small metal components — hinges, pins, tension screws, magnetic catches — and those pit long before anything visible goes wrong. A panel that will not sit shut has failed, however good the blades still look from the driveway.
Add the aspect. East-facing glass on this coast takes direct sun from first light through most of the morning, and a shutter is the one furnishing you can leave closed against the heat while still tilting the blades for air. That is the argument for them here, and it is a better one than the showroom photograph. Where a shutter is not the right call, the rest of our blinds on the Gold Coast usually is.
A shutter you re-hang every third summer is not a window furnishing. It is a subscription.
