  • For replacement windows, “air infiltration” (or, air leakage) refers to the amount of outside air that can sneak in through tiny gaps or openings in the newly installed windows. Minimizing air infiltration helps make your windows more energy-efficient by keeping the air you pay to heat or cool, IN. Plus, unlike solar coatings, tight windows improve your energy-efficiency 24 hours a day! One of the main reasons we recommend OKNA windows is that they are specifically designed to be air-tight. The OKNA EnviroStar Double Hung has an Air Infiltration rating of .01–the best rating on the market!
