Great Lakes Window^® makes a variety of different window styles, from the popular double-hung, vertically sliding windows to dramatic bay and bow windows.

Every style features the innovative technology and quality craftsmanship that is the hallmark of our window.  Features that include:  

• Pinch fusion-welding at the frame corners for superior strength and weathertight construction.

• Heavy-duty fin and pile weatherstripping to provide a barrier to air and water.

• Mainframes filled with patented R-Core^® insulation for maximum thermal performance (and to virtually eliminate frost or condensation on the inside of the frames!).  Optional sash R-Core is also available to further enhance energy savings.

• Warm-edge Intercept^® insulated glass to reduce thermal transfer around the glass perimeter.

• Maintenance-free New Generation Vinyl construction.

• Optional low-emissivity (Low-E) glass systems to reduce energy costs.
