Welcome to the explanation page regarding the interior plantation shutter anatomy. All plantation shutters are not created equal. Plantation shutters are built to last a lifetime of home ownership. Being a hard window treatment allows them to be cleaned (you only need to use a dry dusting product or water to clean them) and the paint used to finish them has an additive that resists peeling, chipping, sun damage, cracking, and becoming brittle due to sun exposure. Additionally, plantation shutters add value to your home with regard to resale, utility cost savings, and reducing sun exposure to furnishings, flooring, etc.
