Inquiry (采购产品): Energy Star Tax Credit We just had your replacement windows installed last week 24 June 2010. It is our understanding that they include argon gas. Do these windows qualify for the Energy Tax Credit? I searced the internet and it says to qualify for the credit the windows' U factor must be less or equal to 0 to .30. Do our windows meet the requirement. They were installed by Ray Construction Co. 212 Whitesville St. LaGrange, GA 30240 Johnny R. & Janis M.
