Founded in 1952, St. Cloud Window designs and manufactures high-performance aluminum fenestration for historically significant and architecturally demanding buildings. The company specializes in narrow-line historic replication windows that preserve original sightlines, profiles, and proportions while meeting contemporary requirements for energy efficiency, acoustics, structural performance, and accessibility. Systems are approved for use on National Park Service–reviewed projects and support federal historic tax credit compliance. St. Cloud’s capabilities extend to acoustically rated windows, terrace and sliding doors, storefronts, and curtain wall systems engineered for urban, coastal, and high-exposure environments. Precision fabrication, customizable muntins and trims, extensive finish options, and rigorous testing ensure durability, longevity, and visual authenticity. The result is advanced fenestration that protects historic character without compromise.
