EAP Vinyl Exterior Shutters: Decorative exterior shutters are an American display of openness and liberty. Today's modern shutters are made from a vinyl material called Polypropylene Copolymer that is maintenance free and lasts a virtual lifetime. Today's vinyl shutters have a wood like appearance and can weather any climate within the United States. As a matter of a fact, this special vinyl can withstand temperatures over 200 degrees. Other well known household items that are made of Polypropylene Copolymer are cutting boards that are used and abused with knifes and dishwashers. At EAP Shutters we guarantee that our Vinyl Shutters are made from the highest quality components of Polypropylene Copolymer.
