I replaced 28 windows in my house with replacement vinyl windows by Ideal Window Manufacturers. This is the 4500 series, low-e, argon filled, double pane glass. Well, we are really cold in this house now. Colder then when we had our 50 year old windows. I've had the manufacturer in twice. The first time he had the installer caulk. The second time he put inch cube styrofoam in the tracks and said the windows are doing what they should be and are good. I've since put up plastic on all the windows and it is bellowing out with air. It is so blown up that it looks like the plastic will burst. This was an expensive job and I can't afford to just redo my windows yet I feel like I am heating the house more then before plus buying portable heaters to supplement. What can I do? Getting a lawyer and suing will cost too much. Help please . . . thanks.
