Aluminum single hung windows are a sleek and practical window solution known for their strength, durability, and modern appearance. In this design, the bottom sash slides vertically while the top sash remains fixed, offering controlled ventilation and a secure closure. The lightweight yet strong aluminum frame resists rust, corrosion, and warping, making it ideal for both residential and commercial buildings. With minimal maintenance and excellent thermal performance when paired with insulated glass, these windows offer long-term energy efficiency.
