Should I Go Halfway Up My Window with Plantation Shutters? A half shutter allows 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 ideal look for a plantation shutter? In the end, 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 letting you close the bottom louvers for privacy while leaving the top louvers open for light. At night, you have the option of closing the top louvers as well for privacy and security. It’s also convenient during the day when the sun is hindering you from watching TV. And don’t worry about forfeiting any of your view. A 3.5" or 4.5" louver will almost disappear when opened flat and gives you abundant space to look through.
