International Window

More than 50 years ago, International Window Corporation began as an aluminum window manufacturer specializing in Jalousie-style windows. As the market changed and diversified, we strategically adapted to meet those expanded needs. Our services grew to also include vinyl windows and sliding and hinged patio doors. Through those years of change and invention, we have maintained a focus of quality and superior customer service for you. Today, we operate two thriving production facilities in Fullerton (Southern California) and Hayward (Northern California).
