Should I Go Halfway Up My Window with Plantation Shutters? A half shutter gives you 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 well-rounded look – and allowing you to close the bottom louvers for privacy while leaving the top louvers open for light. At night, you are able to close the top louvers as well for privacy and security. It’s also convenient during the day when the sun is stopping you from watching TV. And don’t worry about sacrificing any of your view. A 3.5" or 4.5" louver will almost disappear when opened flat and gives you a lot of room to look through.
