Every window we produce is custom made for each opening. A reputable contractor can advise you on what product is suitable for your home and climate. Many of the mass produced mega-store windows are inexpensively built with lower grade raw materials, parts, and hardware. Often times, these windows are designed for multiple uses, such as single-family homes and multi-family dwellings. Our windows are specifically designed and engineered for longevity and efficiency in single family homes.
