We recently had Plantation Shutters installed on our sliding door. We are very happy with the quality and look. This room was both hot and cold. The shutters have made a huge difference. Cooler room when hot outside and warmer when it is cold. Last year we had Plantations put in our family room. Danmer makes a high quality product. Service is top notch and installation is fast and they do a great job at cleaning up when they finish. I would use them again and have told many people about Danmer.
