Polaris Windows

The Polaris Double Hung Window is a versatile, high-quality vinyl window featuring two independently operable sashes (top and bottom) which allow for flexible airflow and easy inward tilt-in cleaning. Crafted with fusion-welded corners, continuous over/under interlocks, and a sloped one-piece sill for positive water drainage, it offers both durability and weather resistance. Beyond the standard build, Polaris offers upgraded options — like foam-filled extrusions, warm-edge spacer systems, and rigid thermal reinforcements — to enhance energy performance and insulation.
