"Superior was founded in 1954 in Southern California as an aluminum window and door manufacturer. During the 1980’s when the country demanded a more energy efficient product Superior started manufacturing vinyl windows and doors. Today our primary products are energy efficient windows and doors. When aluminum is needed Superior still offers a full line of quality aluminum windows and doors.
A key to Superior’s success in California and the Southwest is that we not only manufacture locally but far more importantly, we engineer all of our products for the special needs of your climate.
Since the beginning Superior’s focus has been on quality products, an industry leading warranty and most importantly, customer service which is second to none."
