We discussed several easy measures to improve the performance of existing windows in the Window Improvements page but there is also a product called window film that is professionally applied to existing windows in homes and buildings that cuts infrared radiation by 99%. This eliminates fading from the sun and tempers indoor temperatures better. This product can significantly reduce your cooling load in the summer, and improve the R value of double-paned windows to Low E, triple-paned windows.
