Grilles define style

Grilles define style

Grilles recreate the look of traditional windowpanes and come in a variety of patterns. Add a Colonial pattern to the window units in your replacement bow windows for a traditional look, or a Three-Over-One pattern compliments Craftsman styling. All Great Lakes windows are available with grilles-between-glass or simulated divided lites (on the outside of the glass).

Glass Options

A clear advantage.

Our bow windows 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 vinyl replacement bow 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.
