Enhance your home’s personality with your choice of shaped windows. From half-round to trapezoid, our vinyl replacement windows come in a variety of shapes and sizes for a perfect fit.
Our energy-efficient vinyl shaped windows help reduce your energy bills while making your home more comfortable year-round. It’s the result of fusion-welded multi-chambered vinyl frames, high performance insulated glass units, state-of-the-art manufacturing processes and stringent quality standards.
Our extruded and integral co-extruded colors offer outstanding color retention and durability. Or if you prefer bolder shades — opt for our Signature paint colors.
Grilles recreate the look of traditional windowpanes and come in a variety of patterns. Create architectural interest with an archtop shaped window over a double hung when you add a Radius or Gothic grille pattern paired with a Classic Colonial pattern. Most Great Lakes vinyl replacement shaped windows are available with grilles-between-glass or simulated divided lites (on the outside of the glass).
Our window shapes come with various insulated glass options. Double and triple pane units are available with Low-E coatings suitable for any climate. You can improve the thermal performance of your shaped windows when you combine double-glazing with argon and Low-E. For ultimate performance in cold climates, consider upgrading to triple-glazed units with krypton and Low-E.
Great Lakes Windows provides just as much insulation against heat loss as it does sound. We can configure our replacement shaped windows with double- or triple-glazed glass that is thicker as well as laminated to help keep the noise outside where it belongs.
