Interior plantation shutters are usually made with slats or louvres which can be opened or closed. They are made in synthetic materials or a wide variety of woods. The material depends on the use or position of the shutters. For wet areas, like bathroom or near the kitchen sink, synthetic materials can be used as they won’t be affected by humidity and moisture. Aluminum isn’t a good option for the insides in Sydney as they are good conductors of heat.
