Should I Go Halfway Up My Window with Plantation Shutters? A half shutter lets you have privacy on the bottom and leaves the top open for light and view. It’s called a café style shutter. But is it the appropriate look for a plantation shutter? Ultimately, it’s a style choice – whether you like the look of a half shutter or that of a plantation shutter with a divider rail. A full length shutter with a divider rail “completes” your window, giving it a fully finished look – and giving you the option to close the bottom louvers for privacy while leaving the top louvers open for light. At night, you can close the top louvers as well for privacy and security. It’s also convenient during the day when the sun is preventing you from watching TV. And don’t worry about forgoing any of your view. A 3.5" or 4.5" louver will almost disappear when opened flat and gives you more than enough space to look through.
