Manufacturer of aluminum, vinyl and wood windows and doors. International Window has been a leading window and door manufacturer in the industry for forty years. Established in 1957 in the heart of Los Angeles, International Window began as an aluminum window manufacturer specializing in Jalousie style windows. Strategically adapting to a then growing and changing market, IWC became a diversified manufacturer of windows and doors. With quality and customer service the focus of a rapidly rising company, International Window has continued the trend of maintaining a strategic growth initiative. Today three production facilities exist in Southern California, Northern California and Arizona. The three geographically located facilities create a customer service support network for product distribution. Lead times and back logs are drastically reduced through this micro market philosophy in contrast to today's centrally located mass shipping distribution centers. As a diversified manufacturer, International Window offers products in aluminum and vinyl construction. Windows range from fixed to casement, bay and bow, sliding and hinged to single hung to double hung just naming a few styles. International Window will produce virtually any window style on the market and entertains custom style windows as well. Our fully staffed engineering department ensures market leading designs utilizing cutting edge technology. Yet, code compliance regulations are never compromised.
