after 5 years installed
had our windows installed by stormtight in August of 2015. very pleased with the investment. 5 years of electricity bills being about $100/ month less than before . and during the February freeze it was 17 outside but only got down to 57 inside. no power for 3 days. but the windows helped keep the cold outside. the longer you own them the more impressed you will be with their efficiency
