About International Windows

OUR HISTORY

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). And we maintain a first-class customer service support network for regional product distribution. Lead times and back orders are significantly reduced through this streamlined micro-market philosophy.

OUR PEOPLE

Our dedicated people form the backbone of our organization, which means you receive more personalized service. Trained professionals, they possess a true passion for the business. Our fully staffed engineering department ensures you of market-leading designs that reflect cutting-edge technology and inspired aesthetics, with compliance to all code regulations. At every level, our staff maintains an atmosphere of friendly service.
