The vinyl mainframes of Great lakes Window®
windows are filled with patented† R-Core® insulation (pre-expanded high-density solid-polyurethane), the same type used in many refrigerator/freezer doors. It prevents voids and settling, resulting in even distribution for the maximum insulating barrier.
Your investment in ENERGY STAR windows will pay for itself over time, and then the savings is money in the bank every year!
