Grilles define style

Grilles define style.

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).

Glass Options

A clear advantage.

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.

Glass Options


Sound Resistant

Keep outside noise out.

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.
