Silver Line by Andersen was a brand of affordable, ENERGY STAR® certified vinyl windows and patio doors, known for their energy efficiency and durability. While originally an Andersen brand, the company divested its vinyl window business, including Silver Line, to Ply Gem in 2018. The windows are available for both new construction and replacement projects, featuring low-maintenance vinyl construction in various styles, colors, and sizes designed for different climates and homeowner needs.
