Vinyl window frames are made from polyvinyl chloride, commonly known as PVC, the same plastic used in plumbing and electrical pipes. Several chemicals, fillers, plasticizers and pigments comprise PVC, all of which are available in different grades of quality. Better vinyl window replacement costs more. One indicator of quality is color. If the vinyl has a bluish tint to it, chances are the vinyl window does not have sufficient quantities of titanium dioxide and organic tin. Some vinyl window manufacturers add a bluish tint to their vinyl window frames, which some people think is more aesthetically pleasing. The best indicator of quality vinyl window manufactures is certification from the American Architectural Manufacturers Association.
