The lower of number, the better insulating properties
You want a window with a U-Value under .40. There is a special glass called LowE that will lower that U-Value number. In fact, most quality windows include LowE as standard. Those are the main things to ask about when window shopping. On the opposite end of the quality spectrum, you can buy an economical replacement window that will not have the tilt-in feature.
The mechanism that holds the window open will consist of a block and tackle assembly made up of a spring and string. Another mechanism in lower quality windows is called a spiral tube balance. These lesser grade assemblies are notorious for failing after 5-10 years. The spacer material used on lower quality windows will be aluminum or something called swiggle seal.
And many times the U-Value of these lower grade windows will be up around .50. The thing to remember is that a window that uses a super spacer more than likely isnt going to use a block and tackle balance system. It would be like buying a new car with leather interior and no power window and door locks. Follow those guidelines and you will have a good idea what quality you are buying. Once you make the decision and purchase your windows, it's time to get them home and take out your old windows. In the next article I will tell you how to remove the old wood windows.
