Absolutely! A quality built vinyl replacement window can increase your R-value from 1 up to 9 depending on the glass system you select. These ratings are determined by the National Fenestration Ratings Council (NFRC), a third party testing organization, to accurately rate windows so you compare and make a wise, energy saving decision.
