Where Are Your Shutters Made? The majority the shutters that Sunburst Shutters Boston offers are built here in the USA. Our premier Polywood® plantation shutters are our most popular product and they are extruded, finished, and assembled in the USA. Studio™ shutters and our reclaimed wood shutters are also made right here in America. Our Ovation® real wood shutters are built in several factories, a few of which are located outside the US.
