Our Story

Since 1960, Casco Industries has been a trusted name in high-quality windows, doors, and storm solutions, delivering exceptional customer service and long-term business partnerships. What began as a modest 50' x 100' facility near the historic Elgin National Watch District has grown into a state-of-the-art manufacturing operation. By the late 1980s, Casco expanded its offerings by partnering with leading manufacturers to distribute additional building materials, establishing itself as a premier window and door supplier in the greater Chicagoland area.

Casco Industries is one of the few manufacturers that design, extrude, fabricate, paint, and assemble aluminum-clad wood windows, patio doors, storm windows, storm doors, and porch enclosures entirely in-house. Operating from a 450,000-square-foot facility in South Elgin, IL, Casco maintains full control over quality, durability, and customization—ensuring precision and performance in every product. This vertically integrated approach allows for greater design flexibility, making Casco the preferred choice for homeowners, builders, and architects seeking premium energy-efficient windows, storm protection, and custom patio doors.
