We had PGT windows installed in throughout our house in 2010. In 2015 several windows started getting foggy. We contacted PGT windows immediately and they gave the ok to have them replaced at no cost. However, the company that originally installed them is no longer in business. PGT industries said we should find a new installer and the windows would be sent to them for installation. However, each installer they have given us claims to not be able to get the windows from PGT.
After 3 years of back and forth with PGT representatives we still have foggy windows. My advise, NEVER use PGT windows no matter who installs them.
